Input, output and storage devices

Input Device - An input device is a device that can put information into a computer. An example of an input device is a keyboard. Every time you press a key on the keyboard, you see it on the computer screen.

Output Device - A device that can present information from a computer. For example, computer speakers. It can play music or let your hear the sounds to a video.

Storage Device - A device where memory can be inputted and outputted. An example of a storage device is a USB flash drive. It's small and can still hole up a lot of memory.

What is BIOS?

BIOS stands for basic input/output system. The BIOS makes sure that everything functions together so the computer system can work properly. It's also a BOOT system. When the computer is turned on, the BIOS has to make sure everything is working properly.

Expectations and Goals

What I expect from myself, is that I do all my work, try my best and ask for help if needed. What I expect from my peers, is to help me or asked to be helped. I expect my teacher for helping not only me, but the whole class. Also, I expect to learn many new things about computers that I have never learned before, and learn what each part of a computer does in-order for the whole computer system to function. I have three goals for this class and school this semester:
1. Learn more about computers.
2. Get a very good grade in every class.
3. Hoping this class will help me in the future.

Computer Technology

A computer to me is very important. I pretty much can't live without it. It helps me listen to music and keep in touch with my friends. To my parents, back then it really was nothing. But, these days, my parents both use computers for important things. Such as, doing taxes, paying bills and other things. Without the computer being invented life would be a lot boring.
