Quiz: Hardware Components

What is the primary function of the CPU?

• Storing data

• Executing instructions

• Cooling the system

• Transmitting data

Answer explanation

The primary function of the CPU (Central Processing Unit) is executing instructions. It processes data and performs calculations, making it the core component that drives the operation of a computer.

Which of the following is a characteristic of DDR4 RAM?

• Lower speeds than DDR3

• Improved power efficiency compared to DDR3

• Used only in servers

• Requires dual-channel support

Answer explanation

DDR4 RAM offers improved power efficiency compared to DDR3, allowing for lower energy consumption while maintaining higher performance. This is a key advancement over its predecessor.

Which type of storage device uses magnetic platters to store data?

• SSD

• Flash Drive

• HDD

• NVMe

Answer explanation

HDD, or Hard Disk Drive, uses magnetic platters to store data. Unlike SSDs and flash drives, which use flash memory, HDDs rely on spinning disks to read and write information magnetically.

What is the purpose of the chipset on a motherboard?

• Supplies power to components

• Controls communication between CPU, RAM, and storage

• Houses the CPU and RAM

• Cools the system

Answer explanation

The chipset on a motherboard is crucial as it controls communication between the CPU, RAM, and storage, facilitating data transfer and overall system functionality. This makes it the correct choice.

What form factor is typically used for small form factor PCs?

• ATX

• E-ATX

• Micro-ATX

• Mini-ITX

Answer explanation

The Mini-ITX form factor is specifically designed for small form factor PCs, offering a compact size while still allowing for essential components. Other options like ATX and E-ATX are larger and not suitable for small builds.

What does a PSU's 12V rail primarily power?

• USB devices

• Cooling fans, CPU, and GPU

• SSDs

• Motherboard BIOS

Answer explanation

The PSU's 12V rail primarily powers critical components like the CPU and GPU, as well as cooling fans, which require higher voltage for optimal performance. Other options do not rely on the 12V rail.

Which memory type is non-volatile?

• SRAM

• DRAM

• ROM

• Cache

Answer explanation

ROM (Read-Only Memory) is non-volatile, meaning it retains data even when power is off. In contrast, SRAM, DRAM, and Cache are volatile memory types that lose their data when power is removed.

What does SMART technology in storage devices do?

• Increases speed

• Detects and reports potential drive failures

Answer explanation

SMART technology in storage devices primarily detects and reports potential drive failures, helping users take preventive action. It does not directly increase speed.

Which component contains the Northbridge and Southbridge?

• PSU

• CPU

• Motherboard

• GPU

Answer explanation

The Northbridge and Southbridge are critical components of a computer's architecture, and they are integrated into the motherboard. The motherboard serves as the main circuit board connecting all components, including the CPU and memory.

Which type of RAM is primarily used in CPU caches?

• DRAM

• DDR4

• SRAM

• ECC

Answer explanation

SRAM (Static RAM) is primarily used in CPU caches due to its faster access times compared to DRAM. It retains data bits in its memory as long as power is being supplied, making it ideal for cache memory.
