Computer Science

EDSAC stands for Electronic Delay Storage Automatic Calculator. It was one of the earliest stored-program computers, developed by Maurice Wilkes in 1949, pioneering the use of stored programs in computing.

John von Neumann is known as the father of computer architecture because he developed the von Neumann architecture, which is the foundation for most modern computers. This architecture describes a system where the data and program are stored in the same memory.

Vacuum tubes were used as the main electronic component in the first generation of computers, which lasted from approximately 1946 to 1955. Later generations used transistors and integrated circuits instead.

Third generation computers used integrated circuits, which made them faster and smaller compared to earlier generations that used transistors or vacuum tubes. This improvement led to better performance and reduced size.

The fifth generation of computers is characterized by the use of artificial intelligence, natural language processing, and advanced technologies like bio chips. Therefore, all the options listed (use of natural language, artificial intelligence, and bio chips) are features of fifth-generation computers, making 'All of these' the correct answer.

The integrated circuit (IC) was independently invented in 1959 by Jack Kilby and Robert Noyce, making option B correct. Kilby demonstrated the first working IC at Texas Instruments, and Noyce developed a practical version at Fairchild Semiconductor.

First generation computers operated using machine language, which consists of binary code directly understood by the hardware. Assembly language was introduced later with second generation computers to simplify programming.

The first microprocessor, the Intel 4004, was invented in 1971 by a team at Intel led by Federico Faggin, Ted Hoff, and Stanley Mazor. This team developed the first commercially available microprocessor, marking the beginning of the fourth generation of computers.

Integrated circuits (ICs) were first used in the third generation of computers, which spanned from 1965 to 1971. This innovation allowed computers to become smaller, faster, and more reliable compared to earlier generations.

Procedural programming languages, which use procedures or routines to perform tasks, were primarily developed and used during the third generation of computers, characterized by the use of integrated circuits and high-level programming languages like COBOL and FORTRAN.
