#1. A light sensitive device that converts drawing, printed text or other images into digital form is

Answer: Option C
No explanation is given for this question

#2. Which protocol provides e-mail facility among different hosts?

Answer: Option B
Solution: SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving e-mail. However, since it is limited in its ability to queue messages at the receiving end, it is usually used with one of two other protocols, POP3 or IMAP that let the user save messages in a server mailbox and download them periodically from the server. SMTP usually is implemented to operate over Internet port 25. Many mail servers now support Extended Simple Mail Transfer Protocol (ESMTP), which allows multimedia files to be delivered as e-mail.

#3. The basic architecture of computer was developed by

Answer: Option A
Solution: In 1945, Professor J. Von Neumann, who was then working at the Moore School of Engineering in Philadelphia, where the E.N.I.A.C. had been built, issued on behalf of a group of his co-workers, a report on the logical design of digital computers.

#4. In order to tell Excel that we are entering a formula in cell, we must begin with an operator such as

Answer: Option D
Solution: In MS Excel, formulas are equations that perform various calculations in your worksheets. Though Microsoft has introduced a handful of new functions over the years, the concept of Excel spreadsheet formulas is the same in all versions of Excel 2016, Excel 2013, Excel 2010, Excel 2007 and lower.

All Excel formulas begin with an equal sign (=).

#5. In how many generations a computer can be classified?

Answer: Option C
Solution: 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.

#6. Fifth generation computers are based on

Answer: Option A
Solution: 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.

#7. First generation of computer was based on which technology?

Answer: Option D
Solution: 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.

#8. Microprocessor was introduced in which generation of computer?

Answer: Option B
Solution: 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—from the Central processing Unit (CPU) and memory to input/output controls—on a single chip.

These small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIsthe mouse and handheld devices.

#9. Second generation computers are made of

Answer: Option B
Solution: 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.

#10. Which of the following memory is non-volatile?

Answer: Option C
Solution: Read Only Memory (ROM) is non-volatile memory.
