HW:
If you like most people, computers are becoming a part of your life, and it helps to know how they work. They seem complicated inside, but by understanding just a few parts, you can see a simpler side of computers. This is computer hardware in plain English.
You see them, they come in all shapes and sizes, but word pretty much in the same ways. In fact, if you could look inside these computers, they have the same basic parts. It's these parts, the hardware, that do a lot of work in computers. To explain, let's look at something you already know, a house.
One of the great things about living in house is you have room for all of your stuff. In fact, many houses has basement that become the perfect place for storing things that you want to use later. And the bigger the basement, the more you can store. The same thing is true for computers. Instead of boxes and bicycles, we need a place to store things like photos, music, documents and software. In a computer, it's not the basement, but a hard drive.
A computer's hard drive is where you keep all the things you want to use later. And like basements, the bigger the hard drive, the more you can store. The basements aren't perfect, going to the basement takes too much time whenever you need something. Closet on the main floor can help. They are small and made things easier to access when you need them. You don't need to go all the way down stares.
It's the same with computers. Some of the information stored in our computers is hard for the computer to open quickly, because it needs to take a long way. To solve this problem, computers use ram or a random access memory. It makes information easier for computer to access. This means ram makes computers faster. Plus this kind of close gets cleaned up every time you restart your computer.
Of course, houses have all kinds of parts that need to work together. They would help to has someone like a bartlar in the house, making sure the house is always in working order. If it is too hot, maybe the air-condition is adjustmat. When it's dark, lights are needed. Computers need these, too. Something has to make sure all the parts run smoothly. And computers, this is called the processor. It's a tiny part just like the bartlar of the computer. It's sense receives information, completes tasks and puts the software to work.
And the faster it can complete tasks, the faster your computer will be. So, let's review, the hard drive is like a basement, it stores all the things you need for later. Ram is like a closet on the main floor, it make some information quick and easy to access. And the processor is like having a barrel around, always completing tasks and making things work together.
The next time when you use a computer, take about what's happening under the hurt. Computer hardware is working together to help you get things done. |
