Which of the following languages is often translated to pseudo code?

A)

BASIC

B)

PASCAL

C)

FORTRAN

D)

Assembly

Correct Answer : PASCAL

PASCAL languages is often translated to pseudo code

Pseudocode is an informal high-level description of the operating principle of a computer program or other algorithm. It uses the structural conventions of a normal programming language, but is intended for human reading rather than machine reading. Pseudocode typically omits details that are essential for machine understanding of the algorithm, such as variable declarations, system-specific code and some subroutines. The programming language is augmented with natural language description details, where convenient, or with compact mathematical notation. The purpose of using pseudocode is that it is easier for people to understand than conventional programming language code,

A device mounted on a communication satellite which receives, amplifies and re-transmits signals from earth station is

A)

Transponder

B)

Transistor

C)

Terminal

D)

Track

Correct Answer : Transponder

A device mounted on a communication satellite which receives, amplifies and re-transmits signals from earth station is Transponder.

A communications satellite’s channels are called transponders because each is a separate transceiver or repeater. With digital video data compression and multiplexing, several video and audio channels may travel through a single transponder on a single wideband carrier. Original analog video only has one channel per transponder, with subcarriers for audio and automatic transmission identification service (ATIS). Non-multiplexed radio stations can also travel in single channel per carrier (SCPC) mode, with multiple carriers (analog or digital) per transponder. This allows each station to transmit directly to the satellite, rather than paying for a whole transponder, or using landlines to send it to an earth station for multiplexing with other stations.

3 .

A technique for processing jobs on a first-come, first-served basis is known as

A)

GIGO cable

B)

Optical mark reader

C)

FIFO

D)

FAX

Correct Answer : FIFO

* A technique for processing jobs on a first-come, first-served basis is known as FIFO.

* The phrase is often but erroneously stated as "first come, first serve" (instead of "served"). ...

* FIFO is the acronym for First-In, First-Out.

4 .

The two basic types of record-access methods are:

A)

Sequential and Indexed

B)

Sequential and Random

C)

On-line and Realtime

D)

Direct and Immediate

Correct Answer : Sequential and Random

* The two basic types of record-access methods are sequential and random.

* The terms random access and sequential access are often used to describe data files.

* Comparing random versus sequential operations is one way of assessing application efficiency in terms of disk use.

5 .

B)

Outsized character reader

C)

Operational character reader

D)

Optical character recognition

Correct Answer : Optical character recognition

OCR stands for "Optical Character Recognition." It is a technology that recognizes text within a digital image. It is commonly used to recognize text in scanned documents and images.

The OCR program which will recognize the text and convert the document to an editable text file.

6 .

MODULA is a

A)

Machine language

B)

Assembly language

C)

Programming language

D)

Low-level language

Correct Answer : Programming language

The Modula programming language is a descendant of the Pascal language. It was developed in Switzerland, at ETH Zurich, in the mid-1970s by Niklaus Wirth, the same person who designed Pascal.

The main innovation of Modula over Pascal is a module system, used for grouping sets of related declarations into program units; hence the name Modula. The language is defined in a report by Wirth called Modula. A language for modular multiprogramming published 1976.

millions of instructions per second

B)

multiple instructions per second

C)
