These are :
1. Central Processing Unit (CPU). This is the brain of the computer and performs the basic logical, arithmetic , input & output operations of the computer system.
2. RAM. This is Random Access Memory. It is used by the CPU when the computer system is running to temporarily store information which needs to be used quickly and which would otherwise be lost when there is no power.
3. Motherboard. This is a crucial part that holds together the critical components of a computer including the CPU, memory and input/output connectors.
4.Hard drive. This is the component that stores data permanently.
5. Power supply unit. This is a component that converts mains AC power to DC power for use by the internal parts of the computer.
6. Cooling system. This consists mainly of fans attached to computer enclosures that maintain inflow of cool air and expelling of hot air out of the computer tower.
7. Frame. This is the hard casing that houses the computer parts protecting them and keeping them together.
ARPANET was the network that became the basis for the Internet. Based on a concept first published in 1967, ARPANET was developed under the direction of the U.S. Advanced Research Projects Agency (ARPA). In 1969, the idea became a modest reality with the interconnection of four university computers. The initial purpose was to communicate with and share computer resources among mainly scientific users at the connected institutions. ARPANET took advantage of the new idea of sending information in small units called packets that could be routed on different paths and reconstructed at their destination. The development of the TCP/IP protocols in the 1970s made it possible to expand the size of the network, which now had become a network of networks, in an orderly way.
