What is the function of an operating system in a computer?

• The function of an operating system in a computer is to manage computer hardware and software resources and provide common services for computer programs.

• The function of an operating system in a computer is to play music and videos.

• The function of an operating system in a computer is to control the weather.

• The function of an operating system in a computer is to make coffee for the user.

Explain the difference between RAM and ROM.

• RAM is a type of volatile memory that is used to store data temporarily while ROM is a type of non-volatile memory that stores data permanently and cannot be easily modified.

• RAM and ROM are the same type of memory

• RAM is used for permanent storage while ROM is used for temporary storage

• RAM is non-volatile while ROM is volatile

What is the purpose of a CPU in a computer system?

• The purpose of a CPU in a computer system is to execute instructions and perform calculations for the computer's operations.

• The purpose of a CPU in a computer system is to play music and videos.

• The purpose of a CPU in a computer system is to brew coffee for the user.

• The purpose of a CPU in a computer system is to control the computer's display settings.

Name two types of data storage devices.

• CD-ROM, DVD-ROM

• RAM, CPU

• Floppy disk, Zip drive

• Hard drive, Solid state drive

Explain the concept of virtual memory.

• Virtual memory does not create an illusion of a large memory

• Virtual memory is a type of physical memory

• Virtual memory is a memory management technique that provides an idealized abstraction of the storage resources that are actually available on a given machine, which creates the illusion to users of a very large (main) memory.

• Virtual memory is only used in small computers

What is the function of a router in a computer network?

• The function of a router in a computer network is to encrypt data packets within the network.

• The function of a router in a computer network is to store data packets within the network.

• The function of a router in a computer network is to forward data packets between computer networks.

• The function of a router in a computer network is to process data packets within the network.

What is the difference between a hub and a switch in networking?

• A hub operates at the application layer and a switch operates at the transport layer

• A hub forwards data only to the intended recipient and a switch broadcasts data to all devices connected to it

• A hub operates at the physical layer of the OSI model and broadcasts data to all devices connected to it, while a switch operates at the data link layer and forwards data only to the intended recipient.

• A hub is used for wireless connections and a switch is used for wired connections

Explain the concept of file management in an operating system.

• File management in an operating system involves organizing, storing, and retrieving files. It includes creating, deleting, and modifying files, as well as controlling access to them.

• File management is not necessary in an operating system.

• File management involves managing only the hardware components of a computer system.

• File management is only related to organizing folders, not files.

What is the role of an antivirus software in a computer system?

• To provide entertainment for the user

• To make the computer run faster

• The role of an antivirus software is to detect, prevent, and remove malicious software (malware) from a computer system.
