Answer 2

Answer:

1. Supercomputer- These huge computers are used to solve very complex science and engineering problems. Supercomputers get their processing power by taking advantage of parallel processing; they use lots of CPUs at the same time on one problem. A typical supercomputer can do up to ten trillion individual calculations every second. Example Supercomputers:

K Computer

Columbia

2. Mainframe - computers are similar to supercomputers in many aspects, the main difference between them is the fact that a supercomputer uses all its raw power to focus on very few tasks, while a mainframe perform thousands or millions of operations concurrently. Due to its nature, mainframes are often employed by large organizations for bulk data processing, such as census, industry and consumer statistics, enterprise resource planning and transaction processing.

3. Server computer - A server is a central computer that contains collections of data and programs. Also called a network server, this system allows all connected users to share and store electronic data and applications. Two important types of servers are file servers and application servers.

Servers are a step below supercomputers because they don't focus on trying to solve one very complex problem but try to solve many many similar smaller ones. An example of servers would be the computers that Wikipedia stores its encyclopedia on. Those computers have to go and find the page you're looking for and send it to you. In itself, it's not a big task, but it becomes a job for a server when the computers have to go and find lots of pages for a lot of people and send them to the right place. Some servers, like the ones Google uses for something like Google Documents, have applications on them instead of just files, like Wikipedia.

4. Personal computer - PC is an abbreviation for a Personal Computer, it is also known as a Microcomputer. Its physical characteristics and low cost are appealing and useful for its users. The capabilities of a personal computer have changed greatly since the introduction of electronic computers. By the early 1970s, people in academic or research institutions had the opportunity for single-person use of a computer system in interactive mode for extended durations, although these systems would still have been too expensive to be owned by a single individual. The introduction of the microprocessor, a single chip with all the circuitry that formerly occupied large cabinets, led to the proliferation of personal computers after about 1975. Early personal computers, generally called microcomputers, sold often in kit form and in limited volumes and were of interest mostly to hobbyists and technicians. By the late 1970s, mass-market pre-assembled computers allowed a wider range of people to use computers, focusing more on software applications and less on the development of the processor hardware. Throughout the 1970s and 1980s, home computers were developed for household use, offering some personal productivity, programming and games, while somewhat larger and more expensive systems (although still low-cost compared with minicomputers and mainframes) were aimed for office and small business use.

Today a personal computer is an all-around device that can be used as a productivity tool, a media server and a gaming machine. The modular construction of the personal computer allows components to be easily swapped out when broken or upgrading.
