Study Notes
How Computers Work: A Brief Overview
- The word "computer" was first used in the 1600s to describe people who did math problems.
- Inventors wanted to find a machine that could solve math problems more reliably.
- The first electronic computers were made possible by the binary system and vacuum tubes.
- The binary system uses only the digits 0 and 1 to represent numbers.
- Vacuum tubes were used as switches to represent the digits in the binary system.
- Transistors eventually replaced vacuum tubes, making computers smaller and faster.
- Computers take in information through input devices like a mouse, keyboard, or voice.
- The information is stored on a hard drive or flash memory card.
- The central processing unit (CPU) processes the information and provides output through a screen, speakers, or paper.
- The hardware of a computer includes the keyboard, mouse, and hard drive.
- Software refers to the programs or instructions given to the computer to perform tasks.
- Computers can be found in various devices and use networks to share information.
