What does computer hardware refer to?

• Computer software

• Computer components

• Types of computer system

• Connectivity methods

Answer explanation

Computer hardware refers to the physical components of a computer system, such as the motherboard, CPU, memory, storage devices, and peripherals. These components work together to perform various tasks and execute software instructions. The correct choice is 'Computer components', as it best describes the physical parts that make up a computer system.

What are the types of software?

• Computer hardware

• Applications software

• Utility software

• Operating systems

Answer explanation

The question asks about the types of software. The correct choices are Applications software, Utility software, and Operating systems. Applications software refers to programs designed for specific tasks, Utility software helps manage and maintain computer systems, and Operating systems manage computer hardware and software resources.

What is virtualisation?

• A type of server

• A networking characteristic

• A connectivity method

• A business system

Answer explanation

Virtualisation refers to the creation of virtual resources, such as servers, operating systems, and networks, by abstracting the underlying physical hardware. In this context, a type of server is the correct choice, as it involves creating virtual servers that can run multiple operating systems and applications on a single physical server, thus improving resource utilization and reducing costs.

What are communication skills used in an IT environment?

• Communication technology

• Personal attributes

• Ready for work

• Job roles

Answer explanation

In an IT environment, communication skills are primarily related to communication technology. This includes the ability to effectively use and navigate various communication tools, such as email, instant messaging, video conferencing, and collaboration platforms. These skills are essential for IT professionals to collaborate, share information, and solve problems efficiently.

What are the ethical issues related to computer systems?

• Operational issues

• Threats

• Physical security

• Ethical issues

Answer explanation

The question asks about the ethical issues related to computer systems. The correct answer is 'Ethical issues'. This is because ethical issues in computer systems can include things like privacy concerns, intellectual property rights, and the impact of automation on employment. The other options, such as operational issues, threats, and physical security, while important, do not directly address the ethical considerations.

What is the purpose of utility software?

• To connect computer components

• To troubleshoot hardware

• To perform specific tasks

• To manage communication methods

Answer explanation

The purpose of utility software is to perform specific tasks. It is not used to connect computer components, troubleshoot hardware, or manage communication methods. Utility software is designed to help analyze, configure, optimize or maintain a computer. It is used to support the computer infrastructure, distinguishing it from application software which is aimed at directly performing tasks that benefit ordinary users.

What is the role of an operating system?

• To manage computer hardware

• To develop applications software

• To secure digital data

• To establish communication protocols

Answer explanation

The role of an operating system is to manage computer hardware. It acts as an intermediary between the user and the hardware, managing resources such as memory, processor, disk, etc. It does not primarily develop application software, secure digital data, or establish communication protocols, although it may facilitate these functions.

What is a threat to computer systems?

• Physical security

• Digital security

• Safe disposal of data

• Operational issues

Answer explanation

The question asks about a threat to computer systems. Among the given options, 'Digital security' is the correct answer. This is because threats to computer systems often come in the form of digital attacks, such as viruses, malware, and hacking attempts. These threats can compromise the integrity, confidentiality, and availability of information in the systems.

What are the units of measurement used in hardware?

• Number systems

• Number conversions

• Hardware troubleshooting

• Units of measurement

Answer explanation

The question asks about the units of measurement used in hardware. The correct answer is 'Units of measurement'. This is because hardware components are physical entities and their characteristics such as size, weight, speed, etc., are measured in specific units. Number systems and conversions are mathematical concepts, while hardware troubleshooting is a process, not a unit of measurement.

What are the types of servers?

• Virtualisation

• Networking characteristics

• Connectivity methods

• Types of servers

Answer explanation

The question asks about the types of servers. The correct answer is 'Types of servers'. This is because the other options such as 'Virtualisation', 'Networking characteristics', and 'Connectivity methods' are not types of servers but rather aspects or features that can be associated with servers.
