What is PGA and LGA with respect to CPU configurations?
Press to flip
PGA (Pin Grid Array) and LGA (Land Grid Array) describe how processors are connected to motherboards, differing in pin layout and structure.
What is the primary function of the CPU in a personal computer?
The CPU interprets and executes commands in a personal computer.
Discuss the difference between SATA and NVMe interfaces for storage devices.
SATA is an older interface known for connecting HDDs and SSDs, while NVMe offers faster data transfer speeds using PCIe slots.
Why is RAM considered volatile memory, and how does it enhance system performance?
RAM is volatile because it loses data upon power loss, and it enhances performance by providing rapid access to temporary data for programs.
Name two key safety precautions to prevent electrostatic discharge (ESD).
Using anti-static bags and wearing anti-static wrist straps.
What are two examples of peripheral devices in a computer system?
Peripheral devices include video cards and power supplies.
What advantage do SSDs have over HDDs?
SSDs are faster and more reliable as they have no moving parts compared to HDDs.
What is the role of the Northbridge in a computer's chipset?
The Northbridge handles communications between the CPU, RAM, and PCIe in the motherboard.
Explain the function of BIOS in a motherboard.
BIOS is firmware that initializes and tests hardware at startup and provides runtime services for operating systems and programs.
What is the purpose of a motherboard form factor, and give two examples.
A motherboard form factor defines the size, shape, and layout of the board, such as ATX and Micro ATX.
What purpose do anti-static bags serve in protecting PC components?
Anti-static bags protect components from electrostatic discharge damage during storage and transportation.
How does an expansion card enhance a computer's functionality?
An expansion card adds additional functionality such as improved graphics, network capabilities, or sound.
Identify and explain the purpose of two types of cooling systems in a PC.
Active cooling, such as fans and liquid cooling, moves heat away from components, while passive cooling uses heat sinks to dissipate heat.
Describe the difference between volatile and non-volatile memory, providing an example of each.
Volatile memory loses data when power is lost, such as RAM. Non-volatile memory retains data without power, like ROM.
What is the benefit of modular connectors in power supplies?
Modular connectors allow users to attach only the cables they need, reducing clutter and improving airflow.
