A computer system may be categorised as a:

General purpose or special purpose
Embedded computers
Game consoles and server
Super computers and main frames

Correct Answer

A. General purpose or special purpose

Explanation

A computer system can be categorized as either general purpose or special purpose. General purpose computers are designed to perform a wide range of tasks and can be used for various applications. They are flexible and can be programmed to perform different functions based on the user's needs. On the other hand, special purpose computers are designed for specific tasks or applications. They are optimized to perform a particular function efficiently and may not be as flexible as general purpose computers.

Which of the following best suits the statement below? It's the main memory of the computer system and is volatile.

RAM
ROM
PROM
Primary storage

Correct Answer

A. RAM

Explanation

RAM, or Random Access Memory, is the best fit for the statement because it is the main memory of the computer system and is volatile. RAM is a type of computer memory that is used to store data that is currently being used by the computer's operating system and applications. It is volatile, meaning that its contents are lost when the computer is powered off or restarted. ROM, PROM, and primary storage are not necessarily volatile and may not be the main memory of the computer system.

What does SATA stands for?

Serial Advanced Technology Attachments
Small Advanced Technology Attachments
Serial Advanced Technical Attachments
Small Advanced Technical Attachments

Correct Answer

A. Serial Advanced Technology Attachments

Explanation

SATA stands for Serial Advanced Technology Attachments. This is a type of computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, solid-state drives, and optical drives. The use of the term "serial" indicates that data is transferred one bit at a time, while "advanced technology attachments" refers to the method of connecting the storage devices to the computer. SATA has largely replaced older parallel ATA (PATA) interfaces due to its faster data transfer rates and improved performance.

This primary storage stores data and programs that cannot be changed and is non-volatile.

E-EPRM
PROM
ROM
RAM

Correct Answer

A. ROM

Explanation

ROM stands for Read-Only Memory, which is a type of primary storage that stores data and programs that cannot be changed. It is non-volatile, meaning that the stored information remains even when the power is turned off. Unlike RAM (Random Access Memory) which is volatile and can be both read from and written to, ROM is programmed during manufacturing and its contents cannot be modified or erased by normal computer operations. Therefore, ROM is the correct answer in this case as it fits the description of storing non-changeable data and being non-volatile.

What are types of user interface?

Menu driven, command driven, graphical user interface
File management, memory management, device management
General purpose, customised , integrated
System application, software application, system software

Correct Answer

A. Menu driven, command driven, graphical user interface

Explanation

The types of user interface mentioned in the answer are menu driven, command driven, and graphical user interface. A menu-driven interface allows users to navigate through a series of menus to access different functions or options. A command-driven interface requires users to input specific commands or instructions to perform tasks. A graphical user interface (GUI) uses visual elements such as icons, buttons, and windows to interact with the system. GUIs are more intuitive and user-friendly compared to command-driven interfaces.

An _______ attempt to gain access to information about a company's plans, products, clients, or trade secrets.

Computer fraud
Identity theft
Credit card fraud
Industrial espionage

Correct Answer

A. Industrial espionage

Explanation

Industrial espionage refers to the intentional and illicit attempt to gather confidential information about a company's plans, products, clients, or trade secrets. Unlike computer fraud, which involves unauthorized access to computer systems, identity theft, which involves stealing personal information, or credit card fraud, which involves unauthorized use of credit card information, industrial espionage specifically targets corporate intelligence. This can include activities like hacking into computer systems, bribing employees, or using covert surveillance to obtain valuable information.

Main memory is also known as:

Immediate access storage
Secondary Storage
PROM
RAM

Correct Answer

A. Immediate access storage

Explanation

Main memory, also known as primary memory or internal memory, is a type of computer memory that provides immediate access to data and instructions to the CPU. It is called "immediate access storage" because it allows for quick retrieval of data and is directly accessible by the CPU. Secondary storage refers to devices like hard drives and SSDs, which have slower access times compared to main memory. PROM (Programmable Read-Only Memory) is a type of non-volatile memory that can only be programmed once, while RAM (Random Access Memory) is a type of volatile memory that stores data temporarily during program execution.

All of the following are processing modes except:

Batch processing
Time-sharing
Process
Online

Correct Answer

A. Process

Explanation

The given question asks for a processing mode that is not included in the options provided. The options include batch processing, time-sharing, process, and online. Among these options, "process" is the only one that does not represent a processing mode. "Process" is a general term used to describe a program or task running on a computer, rather than a specific mode of processing. Therefore, "process" is the correct answer as it does not represent a processing mode.

All are secondary storage media except:

Floppy diskette
Compact disk
Magnetic hard disk
Flash memory cards and Fkash drives

Correct Answer

A. Compact disk

Explanation

The correct answer is Compact disk because it is a type of optical storage media, not a secondary storage media. Secondary storage refers to non-volatile storage devices that are used to store data for long-term use, such as floppy diskettes, magnetic hard disks, and flash memory cards/drives. Compact disks, on the other hand, use optical technology to store and retrieve data, making them a different category of storage media.
