[#951] In computer terminology a compiler means
Correct Answer

(D) a program which translates source program into object program

Explanation

Solution: A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer's processor uses. Typically, a programmer writes language statements in a language such as Pascal or C one line at a time using an editor.

[#952] Which part of computer performs functions similar to the cerebrums of the above cardiac and nervous system of a human body.
Correct Answer

(C) CPU

Explanation

Solution: Central processing unit (CPU), principal part of any digital computer system, generally composed of the main memory, control unit, and arithmetic-logic unit. CPU is part of computer performs functions similar to the cerebrums of the above cardiac and nervous system of a human body.

[#953] A storage area used to store data to compensate for the difference in speed at which the different units can handle data is
Correct Answer

(B) Buffer

Explanation

Solution: A buffer, also called buffer memory, is a portion of a computer's memory that is set aside as a temporary holding place for data that is being sent to or received from an external device, such as a hard disk drive (HDD), keyboard or printer.

[#954] A memory that contains a fine pattern of data permanently defined is
Correct Answer

(C) ROM

Explanation

Solution: ROM are very small in memory size. These memory is non-volatile, in the sense, the program stored in ROM don't get erased with power shut down. ROM are used to store permanent programs, which are very essential your hardware to perform correctly.

[#955] What is the number of bits needed for an address in a 4K memory?
Correct Answer

(C) 12

Explanation

Solution: Unsourced material may be challenged and removed. In computer architecture, 12-bit integers, memory addresses, or other data units are those that are 12 bits (1.5 octets) wide. Hence, a microprocessor with 12-bit memory addresses can directly access 4096 words (4 KW) of word-addressable memory.
