the act of working with a computer network
A site where you socialize with other people like facebook, etc.
google is better than facebook because it contains everything,though facebook is the best social ntworking site
If you are thinking about getting to work with computers then I would have say do both courses. Most companies that employ people to look after their computers expect you to know something about the hardward but at the same time there are very few businesses that don't use networking to connect their computers together. If you are just starting out perhaps do the hardware course first as that can help you when you come to do the networking side of things. In addition, i really recommend you to enroll both course in such computer hardware and computer network because this two course have a similar and relevant information when we say hardware it deals with assemble of each part inside of the system unit while networking it study about cabling and interconnection of each computer.
