The computer is a wonderful scientific invention. It is a modern electronic device that can store, organize and find information, do calculation and control other machines. Though it works according to the command of an operator, it performs everything skillfully and accurately. They are an analog, digital and hybrid computer. According to size computer can be classified into four classes. They are a supercomputer, mainframe computer,mini-computer, and microcomputer. A micro computer is also called PC (personal computer). We can communicate with others, send and receive email, arrange a video conference, use different social media and so on. Nowadays, one can get admitted to a foreign university and achieve a higher degree throught the internet. Therefore, I think that it is important to achieve knowledge on computer and internet along with studying the textbooks.
