Multiple Choice Quiz: Computer Components

What is the primary purpose of a TPM (Trusted Platform Module)?

• Store BIOS settings

• Store security keys

• Manage RAM

• Connect peripherals

Answer explanation

The primary purpose of a TPM (Trusted Platform Module) is to store security keys securely. It provides hardware-based security functions, ensuring that sensitive data like encryption keys are protected from unauthorized access.

Where is the CMOS chip located?

• In the hard drive

• On the motherboard

• On the CPU

• In the power supply

Answer explanation

The CMOS chip is located on the motherboard, where it stores BIOS settings and system configuration. It is not found in the hard drive, CPU, or power supply.

What does the ATX motherboard connect?

• RAM and USB devices

• CPU, RAM, power supply, and expansion cards

• CPU and BIOS

• Only the hard drive

Answer explanation

The ATX motherboard connects essential components like the CPU, RAM, power supply, and expansion cards, enabling communication and power distribution among them, which is crucial for the system's operation.

What is Secure Boot designed to do?

• Increase system speed

• Prevent untrusted software from running at startup

• Upgrade the operating system

• Improve internet connection

Answer explanation

Secure Boot is designed to prevent untrusted software from running at startup, ensuring that only verified and trusted software is loaded, which enhances system security.

What type of memory is RAM?

• Non-volatile

• Permanent

• Volatile

• Flash

Answer explanation

RAM (Random Access Memory) is classified as volatile memory because it loses its data when the power is turned off. Unlike non-volatile memory, which retains data, RAM requires a constant power supply to maintain information.

What is BIOS/UEFI used for?

• Manage network connections

• Start up the computer and manage basic hardware settings

• Control display settings

• Install software

Answer explanation

BIOS/UEFI is essential for starting up the computer and managing basic hardware settings, such as boot order and system configuration. It initializes hardware components before the operating system loads.

What does parity checking in RAM do?

• Fix errors

• Detect errors

Answer explanation

Parity checking in RAM is used to detect errors in data storage. It adds an extra bit to data to ensure that the number of bits with a value of one is even or odd, allowing the system to identify if an error has occurred.

Where is a video capture card installed?

• On the CPU

• In an expansion slot on the motherboard

• In the hard drive

• In the RAM slots

Answer explanation

A video capture card is installed in an expansion slot on the motherboard, allowing it to interface with the CPU and other components. It cannot be installed on the CPU, in the hard drive, or in RAM slots.

What does RPM in a hard drive indicate?

• Data storage capacity

• Speed of platter rotation

• Power consumption

• Memory type

Answer explanation

RPM stands for Revolutions Per Minute, indicating the speed at which the hard drive's platters rotate. A higher RPM means faster data access and transfer rates, making it the correct choice.

Which USB version is faster?

• USB 2.0

• USB 3.0

• USB 1.0

• USB 3.1

Answer explanation

USB 3.0 is faster than USB 2.0 and USB 1.0, offering data transfer speeds up to 5 Gbps, compared to USB 2.0's 480 Mbps and USB 1.0's 1.5 Mbps. Therefore, USB 3.0 is the correct answer.
