A computer programmer

A. does all the thinking for a computer
B. Can enter input data quickly
C. Can operate all types of computer equipment
D. Can draws only flowchart

Correct Answer

A. A. does all the thinking for a computer

Explanation

A computer programmer is responsible for writing and designing the code that allows a computer to perform specific tasks. They use their knowledge of programming languages and algorithms to create instructions that the computer can understand and execute. This involves problem-solving, logical thinking, and the ability to break down complex problems into manageable steps. Therefore, the statement "does all the thinking for a computer" accurately describes the role of a computer programmer.

CD-ROM is a

A.Semiconductor memory
B. Magnetic Memory
C. Memory register
D. None of the above

Correct Answer

A. D. None of the above

Explanation

CD-ROM stands for Compact Disc Read-Only Memory. It is a type of optical disc that uses laser technology to read and store data. It is not a semiconductor memory or magnetic memory, as it does not use semiconductors or magnetic materials for data storage. It is also not a memory register, which is a small amount of high-speed memory used to store data temporarily during processing. Therefore, the correct answer is D. None of the above.

The octal equivalent of 111010 is

A. 81
B. 72
C. 71
D. None of the above

Correct Answer

A. B. 72

Explanation

The octal equivalent of a binary number is obtained by grouping the binary digits into groups of three, starting from the rightmost digit. In this case, the binary number 111010 can be grouped as 011 101 0. Converting each group to its decimal equivalent gives us 3 5 0. Therefore, the octal equivalent of 111010 is 350. However, none of the given options match this octal equivalent. Therefore, the correct answer is D. None of the above.

The third generatio of computers covers the period.

A. 1971 - 1982
B. 1982 - 1994
C. 1959 - 1964
D. 1964 - 1971

Correct Answer

A. D. 1964 - 1971

Explanation

The third generation of computers refers to the period from 1964 to 1971. This era was characterized by the development of integrated circuits, which allowed for smaller and more powerful computers. It also saw the introduction of time-sharing systems and the use of high-level programming languages. This period marked a significant advancement in computer technology and paved the way for further innovations in the following generations.

The first mechanical computer designed by Charles Babbage

A. Abacus
B. Processor
C. Calculator c. Calculator c.Calculator
D. Analytical Engine

Correct Answer

A. D. Analytical Engine

Explanation

The correct answer is d. Analytical Engine. The question is asking for the first mechanical computer designed by Charles Babbage. While the abacus is an ancient calculating tool and a processor is a component in modern computers, neither of these options were designed by Babbage. The calculator is also incorrect as Babbage did design a mechanical calculator called the Difference Engine, but it was not his first design. The correct answer, the Analytical Engine, was Babbage's most ambitious design and is considered to be the precursor to modern computers.

The CPU Chips used in a computer is partially made out of

A. Silica
B. Carbon
C. Copper
D. Gold

Correct Answer

A. A. Silica

Explanation

The correct answer is a. Silica. CPU chips, also known as microprocessors, are made using a semiconductor material called silicon, which is derived from silica. Silica is a compound commonly found in sand and quartz. It is used in the manufacturing of computer chips because it has unique electrical properties that allow it to function as a semiconductor, enabling the flow of electric current through the chip. The silicon wafers used in CPU chips are processed and layered with other materials to create transistors, which are the building blocks of the chip's circuitry.

Which of the following is used for serial access storage only?

A. RAM
B. Magnetic tape
C. Magnetic disk
D. Core memory

Correct Answer

A. B. Magnetic tape

Explanation

Magnetic tape is used for serial access storage only because it allows data to be read or written sequentially from one end of the tape to the other. Unlike random access storage devices like RAM, magnetic tape does not allow for direct access to specific data locations. Instead, it requires the tape to be rewound or fast-forwarded to reach the desired data. Magnetic tape is commonly used for long-term archival storage of large amounts of data, such as backups or historical records, where quick access is not a priority.

The memory which is programmed at the time it is manufactured

A. ROM
B. RAM
C. PROM
D. EPROM

Correct Answer

A. A. ROM

Explanation

ROM stands for Read-Only Memory. It is a type of memory that is programmed at the time it is manufactured and cannot be modified or erased by normal computer operations. It contains permanent instructions and data that are essential for the functioning of a computer system. Unlike RAM (Random Access Memory) which is volatile and loses its data when power is turned off, ROM retains its data even when the power is off. PROM (Programmable Read-Only Memory) and EPROM (Erasable Programmable Read-Only Memory) are also types of ROM, but they can be programmed or erased by the user.
