Correct Answer

(C) Scratchpad storage

Explanation

Solution: Scratchpad memory (SPM), also known as scratchpad, scratchpad RAM or local store in computer terminology, is a high-speed internal memory used for temporary storage of calculations, data, and other work in progress.

[#512] What is the name of the logic circuit which can add two binary digits?
Correct Answer

(B) Half adder

Explanation

Solution: The half adder is an example of a simple, functional digital circuit built from two logic gates. The half adder adds two one-bit binary numbers (AB). The output is the sum of the two bits (S) and the carry (C).

[#513] A small film-plate which is used for microfilming the output from a microcomputer screen is called
Correct Answer

(B) microfiche

Explanation

Solution: Computer Output Microfilm (COM) is a system that converts stored data directly to microfilm or microfiche.

[#514] The ALU and control unit of most of the microcomputers are combined and manufactured on a single silicon chip. What is it called?
Correct Answer

(B) Microprocessor

Explanation

Solution: A microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, clock driven, register based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary number system. Source : wikipedia.org

[#515] Continuous line drawing are produced using
Correct Answer

(C) Plotters

Explanation

Solution: The plotter is a computer printer for printing vector graphics. In the past, plotters were used in applications such as computer-aided design, though they have generally been replaced with wide-format conventional printers. A plotter gives a hard copy of the output. It draws pictures on a paper using a pen. Plotters are used to print designs of ships and machines, plans for buildings and so on.
