Question 10

When was the X window system born?
A)1984
B)1989
C)1988
D)1990

Accepted Answer

The X Window System, commonly known as X11 or X, was created in 1984 by the Massachusetts Institute of Technology (MIT) as a platform-independent windowing system for computers with bitmap displays.

Question 11

What is the first stage in software development?
A)specification and design
B)testing
C)system analysis
D)maintenance

Accepted Answer

The first stage in software development is system analysis. This phase involves understanding and documenting what the system needs to do, its requirements, and how it will interact with other systems or users. It sets the foundation for the subsequent stages of software development.

Question 12

Which of the following is valid statement?
A)data in itself is useless unless it is processed
B)the data that is processed is called a program
C)the data which is not yet processed is information
D)information is processed by computer to generate data.

Accepted Answer

Data becomes valuable only when it is processed to generate information, making statement A correct. Statement B is incorrect because processed data is referred to as information, not a program. A program is a set of instructions for processing data. Statement C is incorrect because unprocessed data is not considered information; it's the processing of data that generates information. Statement D is incorrect because it reverses the relationship between data and information; data is processed by computers to generate information, not the other way around.

Question 13

The Second Generation Computer was based on ________.
A)vacuum tube
B)silicon chips
C)transistor
D)bio chips

Accepted Answer

The Second Generation Computers were based on transistors, which replaced the vacuum tubes used in the First Generation Computers, offering smaller, more efficient, and reliable devices.

Question 14

EBCDIC stands for
A)extended binary coded decimal interchange code
B)extended bit code decimal interchange code
C)extended bit case decimal interchange code
D)extended binary case decimal interchange code

Accepted Answer

EBCDIC stands for Extended Binary Coded Decimal Interchange Code, which is a character encoding used mainly on IBM mainframe and IBM midrange computer operating systems.

Question 15

Personnel who design, program, operates and maintains computer equipment refers to
A)console-operator
B)programmer
C)peopleware
D)system analyst

Accepted Answer

Peopleware refers to the human aspect of computing, including personnel who design, program, operate, and maintain computer equipment.

Question 16

IBM System/360 is
A)mainframe computer
B)mini computers
C)micro computers
D)none of above

Accepted Answer

The IBM System/360 is a mainframe computer system family that was announced by IBM on April 7, 1964. It was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific.

Question 17

A system is
A)an integration of different units so as to achieve an objective
B)input unit
C)input and output unit
D)input, output and storage units

Accepted Answer

A system is defined as an integration of different units or components that work together to achieve a specific objective or set of objectives. This integration allows for the processing of inputs to produce outputs in an organized manner, often involving various processes and mechanisms to achieve the desired outcome. Choices B, C, and D describe components that might be part of a system, but they do not define what a system is as a whole.
