The users can avoid health risks by using the computer in proper position. They must also take regular breaks while using the computer for longer period of time. It is recommended to take a couple of minutes break after 30 minutes of computer usage.
Impact on Environment
The computer manufacturing processes and computer waste are polluting the environment. The wasted parts of computer can release dangerous toxic materials. Green computer is a method to reduce the electricity consumed and environmental waste generated when using a computer. It includes recycling and regulating manufacturing processes. The used computers must be donated or disposed off properly . Charles Babbage is called the "Grand Father" of the computer. The First mechanical computer designed by Charles Babbage was called Analytical Engine. It uses read-only memory in the form of punch cards.
Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculatio
Computer
------------------
Computer is an electronic device which is mainly used for calculations, browsing, and computing. We have to give commands to run any kind of computer. for running computer we have to just, give some instructions to the computer and it will give us results.
Computer runs in digital computing. Because of which are able to compute the computer. When we given instructions to computer, then computer instruction is went in OS of that computer. After that, it went in processor and processor send it to display and display shows us.
Computers are faster than our imagination.computer processes so many advanced and high level information in just miliseconds.
There are some many important parts of computers and because of them computer works properly. Processor is one of the most important part of any computer device. Because of processor, that device can be able to perform functions and do work. Computer processors are generally made by Intel and Amd.
RAM is also one of the most important part of computer. Because of which computer is able to show us information in real time. More ram means more efficiency.
OS. Operating system is most important part of any computer. Because UI of our computer is dependent upon OS we are using. If no OS, then no work of that computer.
