Understanding the definition Hardware, What is software, and a definition of Device Driver


In this article, I’ll explain three computer terms, as so many computer terms, do not understand very well with people. And in many cases, are not usually understand

Of course, as always, remember it is not a criticism -. If you do not understand this computer terms before this, it’s just because it was never explained to you properly before.

Let’s see what I can do to fix it.

First off, let me explain the difference between “hardware” and “software”, and just what the terms mean

It’s actually very simple -. “hardware” refers to all the physical pieces of equipment, such as the mouse, the computer’s screen (or screens), the hard drive, etc

“Software” is all parts of the computer that you can not actually see or touch. Software would include things like Microsoft Word, email program, Windows or Mac OS, as well as all the personal files such as letters, photos, music and more

One way to think about it is like .: mechanism is like the brain , the physical part of the body, but the software is like your mind or thoughts -. the non-physical part of you

Software runs on hardware, just as thoughts than your thoughts “run” the brain.

make sense? Now let’s talk specifically about one type of software :. Device driver

What is a device driver? Here’s an easy way to think about what a device driver is.

Imagine that every piece of hardware, including printers, mouse, and so on, speak a different language.

So one speaks French, one speaks Italian, another Cantonese etc.

So when you plug in a new printer and turns it on, the computer says “hi” and the printer answers in a foreign language computer does not understand.

So need an interpreter.

And when I say that outline, I mean just like in the real world, as if a foreign diplomat arrives in the country and not speak the language. They need an interpreter to help them communicate with the local

There, fundamentally speaking, it is a drive -. Interpreter that helps computers talk to a specific piece of equipment. And (generally) you need another interpreter for each piece of equipment that you hook up to your computer.

make sense?

Now, in some cases, the driver may be “content” on your computer (in other words, the computer has already interpreter ready and waiting if it is needed), and in other cases, it must be either insert a CD, or downloaded from the Internet, and then installed on the computer.

But either way, the computer needs a driver before it can talk to a printer, or any other type of device you might have hooked up to the computer.

Hope that makes sense.
