ASCII codes has ____________ bits
Answer: A
Correct answer: 8

High level language includes
Answer: C
Correct answer: both (a) and (b)
COMAL and BASIC are both high level languages: each lets the programmer write in terms of the problem rather than of the machine, and each needs translating before it can run. Standard is not the name of a language.

A program which translates high level program into machine code is classified as
Answer: A

The time required for a pulse to change from 10 to 90 percent of its maximum value is called
Answer: A
Correct answer: Rise time
Rise time is defined as the interval in which a pulse climbs from 10 per cent to 90 per cent of its final value; the 10 and 90 per cent marks are used because the very beginning and end of the transition are hard to identify. Decay time is the corresponding measure for the fall.

Which programming language was designed chiefly for artificial intelligence and symbolic processing ?
Answer: C
Correct answer: LISP
LISP, created by John McCarthy in 1958, is built on list processing and treats code and data in the same form, which suits symbolic manipulation. FORTRAN was written for scientific computation and COBOL for business data processing.

Problem oriented language is
Answer: C
Correct answer: All of the above
