What do you mean by the simultaneous processing of two or more programs by multiple processors?
Answer: C
Correct answer: Multiprocessing
Multiprocessing means two or more processors executing programs at the same instant, which is what the question describes. Multiprogramming and time sharing keep several programs in memory but interleave them on a single processor, so only one instruction is executing at any moment.

In high level programming language BASIC, statements written with GOTO and IF commands are considered as
Answer: A
Correct answer: loop
IF combined with GOTO sends control back to an earlier line when a condition holds, which is a loop built by hand - the way repetition was written before FOR and WHILE were available. The condition is the part that decides when to stop; the construction as a whole is the loop.

Device used to translate programming language into machine code is classified as
Answer: D
Correct answer: assembler
An assembler translates assembly language into machine code, one mnemonic to one instruction. A compiler does the same job for a high level language; an operator and an inverter are not translators at all.

In programming language, 'identifier' can be
Answer: D
Correct answer: all of the above
An identifier is simply a name a programmer gives to something in the program, and arrays, variables and named constants all need names. What distinguishes an identifier from a keyword is that the programmer chooses it.

A name which has some special meaning and significance for programmer is called
Answer: C
Correct answer: reserved words
Words the language keeps for its own purposes - IF, THEN, FOR, PRINT - are reserved and may not be reused as names. It is because they carry a fixed meaning that they cannot be redefined.

Translation of assembly language into machine code is a task of
Answer: C
Correct answer: assembler
Translating assembly mnemonics into the binary codes the processor executes is the assembler's whole function. The programmer writes the assembly; the assembler converts it.
