Advancement in Computer Technology

[ad_1]

5 years ago we gathered around and marveled at the little specs moving at our commands, doing not much – except moving off course, we called these things games. Today the hardware in computers and other devices has changed significantly; we went from having a “spacious” 1mb hard drive to 250 GB of space. The graphics have also taken a giant leap for our computers, no longer are we confined to little dots but our 256mb graphic cards allow us to explore a virtual world in 3d. The sound has also changed from 4bit to 32 and pretty soon 64bit; we went from beeps to actually words. Finally the speed of our beloved computers has also increased from mere kilobytes to gigabytes of rams.

In such a short period of time we went from what we used to call “advanced” technology to today’s much superior devices. So if you guys are like I am, there is one question that strikes our mind, what’s next? Well I would love to say that we will be able to put on our virtual glasses that will allow us to explore the virtual world as if we were in it, but this is not likely, sorry guys; however, these sorts of glasses are being constructed but its unlikely they will come out any time soon. What we can expect to see is an improvement in our Text-to-speech and vise versa programs after the 64bit sound card is released allowing the computer to understand our voices much clearly, also we should soon be seeing more “dept” in our computer as you may know that the most our computers can run on 32bit resolution, it is expected that Microsoft is like to bring out a 64bit resolution with there next version of windows. Also the speed and graphics are to increase a lot more, already some games look as they are almost real, and soon they will look real.

I am not certain exactly what marvel the computer hardware’s will hold in the future, but one thing is certain it will be something to forward too, and once again the next generation will be mocking the so called advanced technology we have today.

Discovering Your Local Area Network

[ad_1]

In the late 1960’s as large college universities and several research labs gained an ever increasing amount of computers, the need for interconnections that worked at high-speed was great, and the pressure was on. It was not until the mid 1970’s that an answer to the demand was created, they called it LAN.

LAN stands for Local-Area Network, with the ability to cover small areas, such as a home or office or group of buildings (schools, warehouse, etc.), LANs have higher data-transfer rates, smaller range and do not require licensed telecommunication lines as opposed to WAN (Wide-Area Network). ARCNET and Token Ring were two LANs that were widely used in the past. Ethernet and Wi-Fi are two of today’s most common LANs.

A LAN is an important component to gamers. By setting up a LAN, gamers can link together their computers and play with or against their friends. Games, such as “Diablo II” and “S.O.C.O.M.”, allows gamers to cooperate together in a team while either on line or while their computers are connected by LAN.Games, such as “Unreal Tournament” and “Starcraft”, allow gamers connected by the internet or a LAN to work as a team or to compete against each other.computers are usually linked by what is known as a Cat-5 cable to a HUB; and the HUB acts like a mediator. The Cat-5 cable connects to the back of the computer through the Ethernet port on the Network card, network adapter, LAN adapter or NIC (Network Interface Card). A network card operates on both the physical layer and the data link layer; it allows a low-level addressing system, using Mac Addresses, also known as an IP address, and physical access to the networking medium (the HUB). Not all LANs are the same; some use cables while others are wireless.

While other network technology exists, since the mid 1990’s, the Ethernet network card has been leading the crowd, due to low cost and easy integration and use. A unique 48-bit serial number is on every Ethernet network card, stored in the ROM; the serial number is your computers Mac address. The Mac address for every computer must be unique; otherwise only one computer with a given Mac address could be on line and connected to the LAN at a time. The Institute of Electrical and Electronics Engineers is responsible for each unique Mac address getting assigned to vendors of interface controllers; this is so no two network cards share the same Mac address.

At one point network cards were expansion cards that had to be plugged into the motherboard. Most new computers have the network card built into the motherboard; some may even have two ports built in so the computer can be connected to multiple networks. Some companies have started using optical fiber instead of Cat-5 cables or USB cords, because optical fiber is immune to electromagnetic interference. Optical fibers are made of glass or plastic, instead of metal, and carry light along their full length. The electrical signals sent along the optical fiber degrade less during transfer than signals sent along metal wires (Cat-5 cables and USB cords).

How To Determine How Much Bandwidth Your Business Needs For Your Computer Network Infrastructure

[ad_1]

Could I suggest a path which is easier to say than to do? The first step is an inventory of what you have, the second step is a measure of the QoS you are getting in real terms… and if you can do one and two then three should be to figure out what you really need to improve or eliminate.

I have noticed that throwing bandwidth at problems is a very typical NA approach whereas in Europe bandwidth has always been more expensive so enterprises have tended to be more efficient.

One area you may care to consider is that if you have T1, E2, fractional, DS3, OC3, MPLS etc (oh let’s throw in cellular, VoIP, TDM and any other part of the alphabet soup) …… you probably don’t have a network architecture and you certainly don’t have a central “entity” responsible for optimising it.

So, inventory, contract review, shorten/lengthen contracts to achieve co-termination and use this time to build a real solution and an effective competitive RFI (ask the vendors for their best ideas) an RFP (marry the best ideas of all vendors) and a final contract. Bearing in mind the 80:20 rule of using a “wild card” supplier to keep the main vendor under some degree of competitive control.

The other piece of the puzzle that has to be consider also is the use of WAN acceleration equipment at each branch office. For your private WAN infrastructure (VPN, MPLS or other), most companies are either evaluating, deploying or have already deployed WAN accelerator appliances. These appliances are really changing the IT landscape so they are a necessary technology for most IT environments these days.

So without getting off topic. In our experience, “most” businesses leveraging WAN acceleration technology with branch offices that have less than 60 users can get away with only installing a T1 private WAN connection. Even with VoIP and other big apps being pushed out to the edge. Most host locations or disaster recovery locations will usually require NxT1 or partial to full T3 connections.

Please understand that there are a ton of variables here that relate to:

-types of users

-applications

-backup

-replication etc.

To break it down just follow this checklist:

1 – Baseline your network so you know what is applications are running on it and how much bandwidth each is using.

2 – Identify critical applications and determine the bandwidth need for adequate performance for each.

3 – Identify the “trash” applications such as “Weather Bug”, internet radio, etc. which can be limited to little or no bandwidth.

4 – Filter your outgoing as well as your incoming traffic on all firewalls.

5 – Write ACLs for your routers or L3 MDFs and which log violations to you management console and analyze the results.

6 – Instigate QoS

7 – Build a Lab that represents the hardware and software infrastructure of you LAN/CAN/MAN/WAN/WLAN and test new applications to verify how they will effect you current bandwidth configuration.

8 – Be proactive as you monitor the bandwidth use and it is growing at a more or less constant rate recommend and add additional bandwidth before you create a bottle neck.

Armed the information above …. and with patience and focus ….. you should arrive at a solid answer for the best bandwidth solution for your network. If you would like free help with the process…..just let us know.

Take What You Need From the Cloud

[ad_1]

Since computers have become commonplace in business, business owners have purchased software and stored their data on machines in their offices. In larger companies, these machines are supported by IT departments made of a few to dozens of technology professionals. Data is sometimes backed up off site but, for the most part, the data has remained inside the walls of each individual office across the country.

In comes the “cloud.” A new revolution in data storage, management and service affording the individual and small business greater computing power than was previously available.

The concept of cloud computing is simple. Data is transferred to and from remote, independently managed servers through internet connections. These servers can be accessed from anywhere and are metaphorically referred to as a cloud hanging above all of its users. The cloud can store data or provide access to Software as a Service TFS.

In its simplest form, your mother might store photos in a cloud for the rest of the family to access from across the country. In its most powerful form, a business can employ the concept of Software as a Service TFS. Cloud computing could mark the end small business servers and the expense of certain retail software packages. Imagine just paying for what you need and when you use it.

The small businesses of America are struggling to grow in these hard economic times. Businesses are struggling to keep pace with the other technology developers. The ideas and the skilled professionals are there but the budget to obtain the needed resources is lacking. Cloud computing services are spreading rapidly.

Let’s not kid ourselves; software from the major manufacturers is expensive. Even if your budget can take the financial hit, there is often little money left to manage the data on local servers. What if you have brilliant employees working from different locations? There are technologies such as TFS web access which can be a remarkable change to the way you do business.

Cloud computing is a new approach to computing services that can give the smallest business the power of the big guys. Software and hardware is expensive, often out of the reach of growing businesses. Team Foundation Server hosting can make the cloud are a reality.

This is a paradigm shift. Rather than buying software and storing data in your office, you can place your computer world in the hands of remote servers. Remote servers that are reliable and subject to regular backups. Instead of buying software, you can rent it for a fraction of the retail cost.

Internet Protocols: How does the Internet Work

[ad_1]

The Internet comprises a plurality of individual computers, each of which are connected to one network. Access protocol, however, apply to this connection. Internet protocols are essentially rules that facilitate communication between individual machines (computers) and the Internet. Applications, such as web browsers and search engines, use Internet access protocols to search for and download the information. But no one piece of software has access to every file, which is located on the Internet; thus, it is necessary to build an arsenal of web sites, subject directories, search engines, and Usenet and email groups to research needs.

Some of the more traditional protocols are HTTP (“The Web”), TELNET, FTP, Usenet, and email.

1. The World Wide Web

The World Wide Web (WWW) is oftentimes confused with “The Internet.” This is understandable, since the WWW represents a large portion of what is available on the Internet. However, the WWW is only one of many protocols Internet access.

Access protocol that forms the basis for the WWW is the HyperText Transfer Protocol, or HTTP. HTTP is a distinct protocol that also offers access to other protocols, such as telnet, ftp, and Usenet and email groups. This is one reason for its popularity – users can search and retrieve information from various protocols without having to learn and connect with each one. The Web is also adept at handling multimedia files and advanced programming language, and is relatively simple, boasting an easy-to-use interface. When conducting online research, you will probably turn to the WWW 99% of the time.

Internet Access Protocol The Web is called HTTP because the WWW uses hypertext to retrieve information. Hypertext is a way to link documents together of words (or graphics) called links. Each time a user clicks on the link, he is directed to another document, one specified by the author’s link. When you visit a website, you use hyperlinks to navigate from page to page within the site. Most sites contain links to other websites as well.

To browse the web, you need to use a piece of software called a web browser. Many browsers employ plug-ins so that they can show multimedia content such as pictures or audio / video files. Even if you are not sure what a web browser is, chances are you’ve used a few. Most popular browsers are Internet Explorer and Mozilla.

2. Telnet

Another Internet Access Protocol you might encounter is the TELNET protocol. Machines that are connected to the Internet sometimes use this program to enable other computers to connect to databases, catalogs and chat services. For example, I often made use of Telnet when taking online distance learning from the University of New Mexico a few years ago. In regular meetings of class, we were obliged to sign telnet once a week and discuss the reading week and homework with classmates virtual directory. Some university use Telnet, although many have moved online catalogs on the web.

In order to launch a telnet session, you first need to install software on your computer and then find a compatible browser. You probably will not work with Telnet very often – and in those cases you do, it will most likely be in your library, which will already have telnet installed on their machines. So, in other words, there is no reason to speed up your computer and install Telnet ASAP!

3. FTP

File Transfer Protocol, or FTP, is exactly what it sounds like – Internet Protocol for transferring files between machines. Users can choose to share files with specific individuals; this is common in the workplace, where colleagues can use FTP to share documents, videos, and other resources with one another. Users can also make their records available for all to download. Anonymous FTP allows users to download files from the host computer on their own machines; Kazaa, BearShare and LimeWire are some popular examples.

FTP search engines allow you to search the Web for files that can be downloaded using FTP programs.

Some (free!) Our search engines are:

File Searching – http://www.filesearching.com/

FileWatcher – http://www.filewatcher.com/

FTP search engines – http://www.ftpsearchengines.com/

FTPSearch – http://www.ftpsearch.net/

While all of the above machines are “generic” directory search engines, you can also use our search engines specifically search for images, audio, video, and new web page. Many of the popular search engines such as Google and AltaVista, with the option to search only for multimedia files, too.

4. Usenet and email discussion groups

Usenet is a system that uses Network News Transfer Protocol, or NNTP. Usenet groups, commonly referred to as forums, discussion groups are devoted to a specific topic. With thousands of forums available, each item of environmental protection Taco Bell is covered.

Email groups are another form of discussion. Instead of NNTP, they use email protocol called Simple Mail Transfer Protocol, or SMTP. As forums, email groups are also around certain subjects. The main difference between the two is that email discussion groups deliver messages that users post right on your computer (talk about convenient!). On the other hand, Newsgroup posts are stored on a central computer. To view the messages, users must connect to the machine that messages are stored and either read them online or download them to their computers.

These panels are very useful for networking and connecting with other people, especially if you need to find experts on a particular subject.

When conducting research, it is useful to understand how the ‘Net functions. For example, files available on websites and messages posted to forums can both be useful to students studies. However, both governed by different protocols and sometimes require different technology research to unearth them.

How to declutter Your Computer

[ad_1]

Did you notice that your computer’s performance had deteriorated over a period of time since you bought? The reason is that your computer has been cluttered with unnecessary files that you’ll never use. Cleaning up your computer on a regular basis and defragmenting a scheduled basis will increase the rate to a considerable extend, if not fully.

I never realized that it happened to me. One day when I was giving a presentation and my head down and I explained my problem. My Desktop was almost cluttered with Excel and Word files icon. He politely asked me to pick it up and I was almost looking there for half an hour but in vain. He explained to me that my problem was that I have not planned or controlled my files properly on my computer and it also reflects the kind of personality I am. . I was really embarrassed by his observation

I decided to declutter my computer immediately and did the following:

I was the first to back up my hard disk to safety, so I do not lose any valuable file that I need to have.

Next I created a folder named Desktop and just blindly pulled all the files on my desktop and dropped it in my new folder. It was really glad to see my desktop so neat and clean. I realized that I was so lazy that I just keep living my files on the desktop and never bothered to register it properly, or scrap it if necessary.

Next I checked the temporary files created under both Windows folder and Internet temporary folder. I never realized that every email attachment I open and close creates a temporary file and it sits permanently until I delete it.

And I searched for files that are not used for more than one year, with advance option in the search panel and I got a long list of files that were never used, but I just kept it on my computer. I scroll just names, and decided that it is no longer necessary. I chose immediately all these files and delete them from your memory. There were countless number of duplicate files that have been created as photographs, many versions of the same file that will never be used by me.

I turned to see what all the programs I’ve been using. More than half of the programs on my Program options were used only once and were never recovered again. I’ve been setting up programs, but never bothered to remove if they no longer need. I went into the settings and my console and remove any unwanted programs from there. There were many games I used to play once upon a time, but were still on my computer. I simply deleted them.

After doing all this cleaning I opened my Recycle Bin and empty it, so I can get a little more space to breathe. I then disk cleanup and defragmentation on my computer. This exercise really did a thorough clean up my computer and restructured or rearranged my files completely. I estimated body defragmenting possibility weekly, so that I can run on its own without the intervention of my people. I decided me henceforth I shall keep records of where they should be, and not leave them on the desktop. I realized going file on the desktop is like going to file on the table.

I was surprised to see how much space I had gained by simply making these measures and also my system had begun to work faster.

How to speed up PC memory – Tips and tricks to speed Machine success

[ad_1]

Over time all computing devices tends to slow down and this leads us to buy modern hardware devices to keep up the up-to-date speed and performance of the computer. This update time can turn to be very expensive and this is why I would like to share with you some of the ways that you are able to speed up PC performance with a fraction of the cost.

First let me explain you why your PC is decelerating, I think it’s very important for you to recognize the cause behind the deceleration. You see the time your computer gets cluttered with their worthless data, what I mean is that the computer is to get littered with “junk”.

What I mean by “junk”

Every time you install and uninstall software files will always remain, primarily registry files. And these files will get cluttered over time, and this is what I mean by garbage.

This is the main cause of the problem so do what you have to send all the garbage registry left over files.

To do that you must take advantage of registry cleaner software, these types of software catch and send invalid, damaged and left over registry files.

additional way to speed up your computer is to send the startup programs you do not use often. To do this simply go home -> Run and type “msconfig” and the Startup tab, check the box last startup programs you do not use often (resume Windows may be necessary). By dispatching this startup programs you can download free computer memory by thirty percent.

effective way to take advantage of PC memory to perform disk defragmenter, this will orchestrate computer files and folders which makes it very easy for the computer to find relevant information. By doing this you will increase your PC speed by twenty percent.

Backup Your Personal Computer to cloud -? A Sensible Strategy

[ad_1]

In today’s world, computers have become an integral part of our lives. Our music, movies, photos and documents are all stored on our computers, where we assume that they will stay at all times. But what about when the unthinkable happens; What will you do to protect your memories and personal documents become victims Law Murphy?

kind can happen that would cause the computer to lose data. A power surge could fry the electronics, rendering the hard drive as nothing more than a brick, metal, and all members of your photos would be history. Or maybe you get a bit overzealous when clean your computer of junk. The terrifying fact is that no data on the computer is safe. Anything and everything can be lost in the blink of an eye. That is where backing up your computer comes into play. The question is, how will you go about backing it up?

There are many options available to the backup computer. External hard drive, for example, are a popular option among many. After connecting the hard drive, behaves like a normal internal hard drive would make it simple to make copies of files you want to keep. However, these are still prone to electrical surges, magnetic field and physical trauma; solid state drives resolve physical injury problems, and boast a very high speed, but are still prone to magnets and power surges, as well as quite expensive. You can also use DVD to backup your data. This removes electrical issues, though DVDs are prone to get scratched, sometimes rendering the data unreadable. It also would require that you have a DVD burner and software to burn DVD.

So what other options are there? Well, one option is to backup files to the “cloud.” The cloud is a term used to describe a cluster server located elsewhere in the world that you can access through the network to either store or retrieve data. The word comes from a description of how networks are diagrammed on paper; when the connection is in the network from the local network, the connection is drawn not to a picture of a computer, hub or other network components, but the picture of, wait for it, a cloud. Backing up files to the cloud is probably one of the safest things you can do to protect your data as it transmits data on site, isolating it from any problems you might experience on the location of the computer. Also, data is sent to multiple servers and multiple copies are created, to ensure that it is always available should a server go down.

On that note, however, you should make sure that the company you use to backup data is reliable and stable, as data will be lost if they close up shop. Also, you need to have Internet access to restore any lost data on your computer, but it is becoming less of a problem these days with almost-ubiquitous broadband availability. In short, backing up your files to the cloud is definitely a sensible strategy compared to the choice.

How to set up a business VoIP system

[ad_1]

to set up a business VoIP system, you need a few things. A central tool for managing phone calls, in the same way and Private Branch Exchange (PBX) or Key System Unit (KSU) makes traditional phone systems is one of them.

This can be a dedicated piece of hardware such as IP PBX, a regular PBX that has been IP-enabled, or servers running specialized software. You also have phones and data networks. In many cases, you may be able to use your existing digital phones and a computer, although you may need to upgrade some of your networking hardware.

VoIP Benefit

The most visible benefit of IP PBX for companies with multiple locations. With the advantages of VoIP, all offices on a LAN or WAN can profit from having a common office phone system. Gains are -. Extension dialing, seamless call transfer, and other functions

In addition to making it easier to communicate, these visual features can increase co-workers in different locations can truly feel like they are part of the same structure. Plus, if they are on the company network, calls are free – even if the offices are located thousands of miles apart. It is possible to collect the money spend on the job between the two branches of the same office

VoIP Conversations

Computer networks are designed to handle messy data :. Kits come out of order and some have even lost, but in most cases the data being sent can easily be reconstructed when needed. Voice conversations, however, are not as tolerant of these types of interference. Each package of sound must be in the correct order because they are sent in real time – if the package is lost; conversation sounds distorted, choppy, or fall off all together. This is why VoIP services that rely on the Internet to transmit calls can be uneven quality phones.

Selecting a business VoIP solution is a big decision. Voice service is important to the company’s operations, so no one wants to implement technology that will compromise the quality or reliability in any way. On the other hand, cost savings and value-added functionality available with VoIP makes it a compelling investment.

LANs & WANs

The VoIP phone system is useful for companies that have multiple locations branches, telecommuters and remote sales offices. Standard are associated with the company’s Local Area Network (LAN) or Wide Area Network (WAN). In that case, companies are suitable to use VoIP systems.

You can share the full features of your phone system at all positions. Besides, even if you have one office in one place and one second place, VoIP allows calls between the extension dialing, making it a zero cost call. For companies with hefty monthly long distance charges for calls between far away places, is an attractive reason to upgrade.

VoIP Process

A VoIP sound process requires regular phones, adapters, broadband Internet access, and subscription to VoIP service. When you place a call, it is sent via the Internet and data access to the destination recipient.

Then, the call is translated back to a more traditional format and ends go over standard phone lines. Also known as Internet telephony, this allows for very cheap long-distance and international calls.

VoIP drawbacks

The main drawback of VoIP systems is network requirements.

The VoIP telephony greatest challenge is bandwidth. It requires high bandwidth for a clear message.

Voice Activated Technology

[ad_1]

In the last two years, many software vendors have been working on voice activated technology. We remember 2001 A Space Odyssey with the HAL computer. I was fascinated by the ability to talk to the computer and the artificial mind talking back to us. The next time I came across computers was while watching Star Trek. We could talk to the machine and with only our voice commands that take us to the bridge or make an entire meal appear out of thin air. It seemed like a great idea at the time but no one believed that you would ever really be able to experience this wonder, at least not in our lifetimes.

However, today we are much closer to those fantasies. I’m dictating this article with voice activated software. In a word, I will be saving time in the future to prepare for upcoming articles with this new technology. For now I am learning along with my trusty laptop.

I tried older versions of voice activated software a few years ago and found it frustrating from the point of view of accuracy and difficult to use the document I was working on. This latest version is much better to navigate through the computer and it is also faster and fairly accurate. Say the word ‘Vista’ and looking at the screen and the computer hears your command and you really start to save the document has odd combination of amazement and joy.

However, the price to pay for this thrill. Study selection of new orders and in some cases to deal with the computer as it misinterprets what you’re saying bear frustration level different from existing technologies anxiety. After all this is the answer we have been waiting for, the last step to make computers accessible to everyone including the infamous two-fingered typist. On the plus side when you speak a complete sentence and watch the computer typing it out in front of your eyes with no mistakes and it’s pretty hard to believe.

But how does this new technology, apply to marketing? Marketing is a lot of thinking and writing and rewriting. No sit down to write a marketing plan in a single pass or create the perfect copy for their website, an advertisement or a brochure with a first draft. So, in theory, if the technology helped you to do some of the things you usually spend enough time then maybe you would be able to provide them with valuable marketing materials in less time and get them to customers more efficiently.

We all have good intentions when it comes to answering e-mail, send a follow-up thank you letter in a timely manner and create proposals all require a fair bit of time parked in front of the computer.

Some will use their unfamiliarity or discomfort at the computer to prevent this project. Unfortunately, the computer is not going to perform these functions completely without assistance, but used properly can make tasks easier.

I’ve benefited from the voice activated technology to input large copy. For example, I wanted to use the information from the previous brochure client has provided. I have in the past had two options. I could input the information yourself or have my assistant do it. Now I have a third choice, I put on my headset with integrated microphone and order copies directly into your computer saving hours of two-fingered typing.

When I read through the literature and get more familiar with this software I realize that I can use it to fill my inner forms automatically tabbing from field to field by processing customer orders reduced rate. One of the major improvements, the sales and marketing point of view, which has helped many modern fast-rising companies build their business has been able to process orders much more effective and timely than its competitors. When a client requests within or makes calls for services they are not willing to wait two weeks after birth or they will wait a week or even 48 hours in most cases when someone needs something they need it immediately. The more efficient you are getting the order from the beginning customers request the account may decide how long you stay in business.

Leaving presentation of new features or existing customers and returned to the office with rough notes is standard procedure for many business today. Take the rough notes and inputting them into a computer and turn them into the next step helps keep you organized and reduces the amount of things that might fall through the cracks.

Voice activated technology is about speed and volume. The more you can do and the faster you can do that will help to make you more competitive. As technology improves you will be able to dictate memos, letters, invoices, orders and other correspondence with ease and efficiency that has never been seen before. Those who pride themselves on their lack of computer capabilities will be left behind.

I’m often asked how small businesses compete against large companies. If you can do the same kind of work, at the same time as larger competitors and at approximately the same price it is a good chance to win this opportunity.

There have always been innovators and followers of the company. By adopting new technology at the beginning of the innovation level you can be one of the first to reap the rewards after the service your customers better than the competition.

Every so often I hear the phrase from the small businessperson “I’m so busy ‘when asked how their business is doing. The” busy “does not always equate to profit. I’ve written in the past about to turn down work or project if they are not the right ones for your business. Modern technology can help you service more good projects and turn engaged in profits. There is nothing worse than take a chance because you do not have time. Customers can catch the first time you turn them down but rarely take another.

And under 2 Eric
