How Computers Work
Do you know how computers work???
Basics of computers
What a computer mostly needs is hardware,software, input, and output.
what things mean
Motherboard- it is where u find the main processing chips. the chips are made up of central processing unit which is also called CPU.
Hardware- is the monitor, keyboard, printer, mouse, and speakers.
Software- any operating information used by the computer like programs. Its tells the hardware what to do.
Input- telling the computer what to do by clicking anything or typing.
Output- It's where power or information leaves the system.
Computer Systems and network
Networking computers share their power by linking 2 or more computers together. To link 2 or more computer together they use something called '' the server''. They share there power so they can exchange applications and exchange data files and information.
Printer
If u want to print a page you click the print icon which tells the computer what to do. The software determines if there is a printer attached to the computer and if its turned on. If your computer is not turned on it will send a message saying to turn on the printer.
Most Computers are classified as :
- Mainframe Computers
- Mini computers
- Micro Computers
- Palm Top Computer
- Embedded Computers
These are computer parts
1 generation
The main features were:
- Vacuum tube technology
- Unreliable
- Supported machine language only
- Very costly
- Generated lot of heat
- Slow input and output devices
- Huge size
- Need of A.C.
- Non-portable
- Consumed lot of electricity
2 Generation
The main features were:
- Use of transistors
- Reliable in comparison to first generation computers
- Smaller size as compared to first generation computers
- Generated less heat as compared to first generation computers
- Consumed less electricity as compared to first generation computers
- Faster than first generation computers
- Still very costly
- A.C. needed
- Supported machine and assembly languages
3 Generation
The main features were:
- IC used
- More reliable in comparison to previous two generations
- Smaller size
- Generated less heat
- Faster
- Lesser maintenance
- Still costly
- A.C needed
- Consumed lesser electricity
- Supported high-level language
4 Generation
The main features were:
- ULSI technology
- Development of true artificial intelligence
- Development of Natural language processing
- Advancement in Parallel Processing
- Advancement in Superconductor technology
- More user friendly interfaces with multimedia features
- Availability of very powerful and compact computers at cheaper rates
