Computers Part 1

Just about anyone can recognize a computer. Computers are common enough now that even someone stomping through a junkyard and searching for the left front end of a 1988 Subaru would be able to recognize one. But, do you know what a PC really is? There’s more to a computer than just a consumer gadget that you can quickly assemble and “be up and running in
no time.” Despite advances in technology and strides toward making things “user-friendly,” the computer remains a highly technical device. If you’re going to get the most from your computer, you’ll have to be formally introduced. That’s what you’ll find in this blog.

Most gizmos are rather simple: A toaster heats bread; a microwave oven heats water or the water inside of things; a car provides transportation; a telephone allows you to talk with someone else, from across the globe to sitting across the table. The purpose of any device can be boiled down to the simplest description. But what about a computer? It has been said that computers defy description. At one time, the computer was considered the ultimate solution for which there was no problem. But that’s not quite correct. The computer is a simple beast. It doe basically one thing: It takes input and then modifies that input to create some form of output. The enormous potential of that simple activity, however, is what makes the computer seem like such a complex device.


To help you grasp the notion of what a computer does, you should understand
three basic computer concepts:
 I/O
 Processing
 Storage
We will be discussing about them in the subsequent posts one by one.
