SATA cables are used to connect internal storage devices such as hard drives and SSDs to the motherboard. They enable high-speed data transfer between the storage devices and the rest of the computer system.
Which expansion slot is most commonly used for modern graphics cards?
ISA Slot
AGP Slot
PCIe x16 Slot
PCI Slot
Modern graphics cards are designed to use the PCI Express (PCIe) x16 slot because it provides the necessary bandwidth for high-definition graphics. This slot has largely replaced older standards like AGP and PCI for video processing.
What is the primary function of the chipset on a motherboard?
Cooling the system
Facilitating communication between the CPU and other components
Generating power for the system
Storing long-term data
The chipset acts as a communication hub on the motherboard that links the CPU with memory, storage, and peripheral devices. It plays a crucial role in determining the system's overall data transfer speeds and compatibility.
Which component converts digital audio signals into analog signals for playback through speakers?
Graphics Card
Sound Card
Power Supply
Network Card
The sound card processes digital audio data and converts it into analog signals that speakers can use to produce sound. This conversion is essential for audio playback in computers.
Which internal component is dedicated to managing network communications in a computer?
GPU
Network Interface Card (NIC)
CPU
SSD
The Network Interface Card (NIC) enables a computer to connect to and communicate over networks. It handles the transmission and reception of data through wired or wireless connections.
Which component stores volatile data that is lost once the computer is turned off?
Hard Drive
Power Supply
RAM
ROM
RAM, or Random Access Memory, is used to temporarily store data that the computer actively processes. Its volatile nature means all stored data is lost when the system is powered down.
What does the term 'overclocking' refer to in computer hardware?
Installing additional RAM
Running a component at a speed faster than its rated specification
Changing the power supply voltage
Updating the BIOS
Overclocking involves increasing a component's clock rate beyond the manufacturer's rating to achieve better performance. This practice requires enhanced cooling solutions to manage the additional heat generated.
