ExaMocks - History and Generations MCQ With Solution

Explanation

Answer is : C
There is 5 generation of computer available till now. 1st Generation of Computer = The period of first generation: 1946-1959. Vacuum tube based. 2nd Generation of Computer = The period of second generation: 1959-1965. Transistor based. 3rd Generation of Computer = The period of third generation: 1965-1971. Integrated Circuit based. 4th Generation of Computer = The period of fourth generation: 1971-1980. VLSI microprocessor based. 5th Generation of Computer = The period of fifth generation: 1980-onwards. ULSI microprocessor based.

Explanation

Answer is : A
Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.

Explanation

Answer is : D
The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts. The UNIVAC and ENIAC computers are examples of first-generation computing devices.

Explanation

Answer is : B
The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer

Explanation

Answer is : B
Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output. Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN.

Explanation

Answer is : C
ENIAC was designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania, U.S.

7. The ............ operating system was initially created in the early 1970s at AT & T's Bell Labs.

None of these

Explanation

Answer is : B
International Business Machines Corporation, perhaps better known by its acronym IBM, is called the Big Blue.

Explanation

Answer is : B
