Super computer
Mini computer
Mainframe computer
Micro computer E. None of the above

ILLIAC is a type of supercomputer. It was developed at the University of Illinois at Urbana-Champaign and was one of the first supercomputers to be built. ILLIAC was used for a variety of scientific and engineering applications, including weather forecasting, nuclear weapons design, and fluid dynamics.

A supercomputer is a computer that is designed to perform very complex calculations very quickly. Supercomputers are used for a variety of applications, including weather forecasting, climate modeling, nuclear weapons design, and fluid dynamics. Supercomputers are typically much more expensive than other types of computers, and they require a lot of power to operate.

A minicomputer is a type of computer that is smaller and less powerful than a mainframe computer, but larger and more powerful than a microcomputer. Minicomputers were popular in the 1970s and 1980s, but they have since been largely replaced by personal computers.

A mainframe computer is a large, powerful computer that is used for a variety of applications, including data processing, scientific computing, and business applications. Mainframe computers are typically used by large organizations, such as banks, insurance companies, and government agencies.

A microcomputer is a small, personal computer that is used for a variety of applications, including word processing, spreadsheets, and games. Microcomputers are also known as personal computers (PCs) or home computers.

The correct answer to the question “ILLIAC is a” is A. Super computer.
