A computer is an electronic device which works under human instruction. A computer can make our day-to-day work easier and faster. The main advantage of using a computer is fast access. A computer can perform thousands and millions of commands per second. Some other examples are flexibility, reliability and storage capacity.
Unfortunately, there are some disadvantages. The main one is that it causes environmental pollution due to the nonstop use. If we use it for a long time, it may cause repetitive strain injuries such as back pain, neck pain and headaches. We should use computers for a short time for our own health.
