A name applied by Intel corp. to high speed MOS technology is called
Answer: C
Correct answer: HMOS
HMOS - High-performance Metal Oxide Semiconductor - was Intel’s name for the scaled-down NMOS process it introduced in the 1970s, giving faster switching and greater density; the 8085 and 8086 were built with it. HDLC, LAP and SDLC are data-link communication protocols.

What difference does the 5th generation computer have from other generation computers?
Answer: A
Correct answer: Technological advancement
The first four generations are each marked by a change of switching technology, and the fifth is marked in the same way - by very large scale integration and parallel processing put to the service of artificial intelligence. Object-oriented programming is a software development and belongs to no generation of hardware.

_____________ contains specific rules and words that express the logical steps of an algorithm.
Answer: B
Correct answer: programming language
A programming language supplies the vocabulary and the grammatical rules in which an algorithm’s steps are written so that a machine can carry them out. Syntax is the set of rules alone, without the words; a flowchart shows the logic as a picture rather than as statements.

What is full form of IP ?
Answer: C
Correct answer: Internet Protocol
IP is the Internet Protocol, the network-layer protocol that gives every host an address and routes packets from one network to another. It promises only best-effort delivery; TCP, running above it, adds the acknowledgements and retransmissions that make a connection reliable.

Which is responsible for performing modulation/demodulation ?
Answer: C
Correct answer: Modem
Modulation impresses digital data on an analogue carrier and demodulation recovers it at the far end - the two operations a modem is named after. Fibre and coaxial cable are transmission media, and a router forwards packets between networks.

An operating system intended for use on microprocessor based systems that support a single user is
Answer: D
Correct answer: CP/M
CP/M - Control Program for Microcomputers, written by Gary Kildall in 1974 - was the first widely used operating system for 8-bit microprocessor machines, single-user and single-tasking. MS-DOS and PC-DOS came later for the IBM PC, and Unix is a multi-user system.

A number which is stored and processed but not in the standard exponential form is called
Answer: B
Correct answer: Fixed point number
In a fixed point representation the binary point is at an agreed position, so every value carries the same number of fractional digits and no exponent is stored. Floating point is the standard exponential form, holding a mantissa and an exponent so the point can move.

Which computer has been designed to be as compact as possible?
Answer: C
Correct answer: Micro computer
A microcomputer puts the whole processor on a single chip, which is what allows the entire machine to be built into a desktop or portable case. Minicomputers occupy a cabinet, and mainframes and supercomputers fill a room.

Which of the following computer language is used for artificial intelligence?
Answer: B
Correct answer: PROLOG
PROLOG - PROgramming in LOGic - states facts and rules and lets the system infer answers by resolution and backtracking, which suits the knowledge representation and inference that artificial intelligence work needs. FORTRAN is for numerical work, COBOL for business data processing, and C for systems programming.

Most important advantage of an IC is its
Answer: B
Correct answer: Extremely high reliability
Putting a whole circuit on one chip removes the soldered joints and connections between separate components, and it is those interconnections that fail most often. The result is a very large gain in reliability - and lower cost, smaller size and less power follow from the same integration, but they are consequences rather than the principal advantage.
