Computer Components Quiz

What is the main role of a processor in a computer system?

• To store long-term data

• To transfer data between servers across a network

• To manage the functions of a computer system by processing data and instructions

• To convert electricity from AC to DC

What is the primary processor of each computer system?

• Random Access Memory (RAM)

• Cache Memory

• Central Processing Unit (CPU)

• Read-Only Memory (ROM)

What is the main circuit board of a computer on which components such as the CPU and ROM are connected?

• Read-Only Memory (ROM)

• Motherboard

• Power Supply Unit (PSU)

• Random Access Memory (RAM)

What is the purpose of non-volatile storage?

• Converts analogue sound waves into digital data

• Saves the data even when not being powered, so it can be accessed when the computer is next on and can be stored long-term

• Stores data that is frequently accessed

• Stores all programs that are currently running

Which secondary storage medium has the slowest access speed?

• Magnetic Storage

• Optical Storage

• Solid State Storage

• Cloud Storage

What is the purpose of a Network Interface Card (NIC)?

• Converts analogue sound waves into digital data when inputting audio through a microphone

• Processes graphical data and converts it into a displayable output on a monitor

• Transfers data between servers across a network

• Allows computers to connect to networks and enables them to transfer data to other computers

What is the purpose of a USB Port?

• Connects storage devices such as USB sticks or external hard drives

• Allows data transfer to external HDD, SSD or optical drives

• Enables data from an SD card to be transferred from a device like a camera to the computer

• Connects computers to network devices such as a modem or router

What is the difference between SCSI and SAS?

• SCSI is a protocol for attaching external devices to a computer system, while SAS is an improved version of SCSI that enables many more external devices to be connected at the same time

• SCSI allows for quick transfer speeds and is primarily used to connect data storage to servers in large data centres, while SAS is a protocol for attaching external devices to a computer system

• SCSI is primarily used to connect data storage to servers in large data centres, while SAS is a protocol for attaching external devices to a computer system

• SCSI is an improved version of SAS that enables many more external devices to be connected at the same time to a computer system

What is the purpose of a Graphics Card?

• Transfers data between servers across a network

• Allows computers to connect to networks and enables them to transfer data to other computers

• Converts analogue sound waves into digital data when inputting audio through a microphone

• Processes graphical data and converts it into a displayable output on a monitor

What is the purpose of the motherboard?

• To store long-term data

• To manage and connect all the components of a computer system

• To convert electricity from AC to DC

• To transfer data between servers across a network
