A) A Supercomputer
B) A PC
C) A Minicomputer
D) A Workstation
E) A Mainframe

Accepted Answer

A mainframe is best suited for handling the computing needs of multiple users, such as 75 workers, as it is designed to manage large amounts of data and support numerous simultaneous users efficiently.

Question 9

Which of these is NOT one of the key computer hardware components?
A) Central Control Unit
B) The Primary Storage
C) The Secondary Storage
D) Inputting Devices
E) Outputting Devices

Accepted Answer

The correct term is "Central Processing Unit" (CPU), not "Central Control Unit." The other options are indeed key computer hardware components.

Question 10

What is the main advantage of an ink-jet printer over a laser printer?
A) its lower cost
B) its greater speed
C) both of the above
D) it looks better
E) none of the above

Accepted Answer

Ink-jet printers are generally less expensive than laser printers, making their lower cost the main advantage.

Question 11

Which of the following is not normally a means of transforming data into information?
A) Sorting
B) Summarising
C) Classifying
D) Retrieving
E) Inputting

Accepted Answer

Inputting is the process of entering data into a system, not transforming data into information.

Question 12

Which one of the following functions is NOT performed by a transaction processing system?
A) Edit all inputs to ensure that it is accurate and complete
B) Access files of basic information to edit and input transactions
C) Enable users to access strategic external information sources
D) Generates the necessary transactions to communicate to higher level systems in a summarised form
E) Has to be accurate at all times

Accepted Answer

A transaction processing system is primarily concerned with processing business transactions efficiently and accurately. It does not typically enable users to access strategic external information sources, which is more characteristic of decision support systems or executive information systems.

Question 13

All of the following are types of tangible software except:
A) systems software
B) operating software
C) management decision making software
D) application software
E) cyberspace software

Accepted Answer

Cyberspace software is not a recognized category of tangible software. The other options are types of software that can be physically installed and used on a computer system.

Question 14

Which language is the hardest for humans to write and understand
A) machine code (Binary)
B) assembly language
C) COBOL
D) BASIC
E) PASCAL

Accepted Answer

Machine code (Binary) is the hardest for humans to write and understand because it is a low-level language that is directly executed by the computer's processor.

Question 15

Which of the following has limited facilities for mathematical notation but
has excellent facilities for character data processing and business use?
A) FORTRAN
B) COBOL
C) PASCAL
D) ADA
E) VORGON

Accepted Answer

COBOL is a programming language specifically designed for business use, and it has excellent facilities for character data processing.

Question 16

What is the essence of object-oriented programming?
A) versatility
B) objectivity
C) inheritance
D) all of the above
E) removing the human from computer programming

Accepted Answer

Object-oriented programming (OOP) is characterized by versatility, objectivity, and inheritance, among other principles like encapsulation and polymorphism. These features collectively define the essence of OOP.

Question 17

The basic data storage hierarchy consists of (in order from the smallest
upwards):
A) byte, bit, record, file, field and database
B) byte, bit, field, record, database, file
C) bit, byte, field, record, file, database
D) bit, byte, field, file, record, database
E) data, information, knowledge, wisdom

Accepted Answer

The correct order of data storage hierarchy is bit, byte, field, record, file, and database.

Question 18

A file in database terms is:
A) the field which uniquely identifies a record
B) a collection of related records

Question 20

The link between the logical view and the physical view of data is the:
A) application program
B) DBMS
C) database
D) programming
E) Data Flow Diagrams

Accepted Answer

The DBMS is the link between the logical view and the physical view of data. The logical view is the way that users see the data, while the physical view is the way that the data is actually stored on the computer. The DBMS translates between the two views, so that users can access the data in a way that is convenient for them, without having to worry about the details of how the data is stored.
