What is a switch?

A switch is a networking device that connects multiple devices within a Local Area Network (LAN) and intelligently forwards data only to the intended destination device.

What is ATX?

ATX (Advanced Technology eXtended) is a standard form factor for computer motherboards, power supplies, and computer cases. It defines the physical size, mounting points, power connections, and layout of components inside a desktop computer.

200

This type of memory is volatile and loses data when power is removed.

RAM

What is POST?

POST (Power-On Self-Test) is a diagnostic process performed by the BIOS or UEFI when a computer is powered on. It checks that essential hardware components are functioning correctly before the operating system loads.

200

What is a LAN?

This network type covers a small geographic area such as a home, school, or office.

200

What is DNS?

This protocol translates domain names into IP addresses.

What is an IDE/PATA cable?

IDE/PATA (Integrated Drive Electronics / Parallel Advanced Technology Attachment) cable is a flat ribbon cable used in older computers to connect storage devices such as hard disk drives (HDDs) and optical drives (CD/DVD drives) to the motherboard.

300

What is a heat sink?

A heat sink is a metal component that is mounted directly on the CPU to absorb and dissipate heat away to prevent overheating.

What is the possible cause of display failure?

A display failure (no image or blank screen) can be caused by several hardware or software issues. It is usually related to power, connection, graphics hardware, or monitor faults.

300

What is Cat 6?

This twisted-pair cable category supports speeds up to 10 Gbps over short distances.

300

What is ICMP (Ping)?

This TCP/IP protocol is used to test connectivity between two devices.

400

What is CMOS?

CMOS (Complementary Metal-Oxide Semiconductor) is a small amount of memory on the motherboard that stores important system configuration settings, such as the date, time, boot order, and hardware settings.

400

This storage device uses flash memory and has no moving parts.

SSD

How to troubleshoot display issues?

Display issues are troubleshooted by checking power connections, verifying video cables, testing the monitor on another system, reseating the graphics card and RAM, checking BIOS settings, and updating or reinstalling display drivers.

What is 802.11ac?

This wireless networking standard operates exclusively in the 5 GHz band and is known as Wi-Fi 5.

400

What is Network Address Translation (NAT)?

This technology allows multiple private IP addresses to share a single public IP address when accessing the internet.

500

What is PCIe x16?

PCIe x16 (Peripheral Component Interconnect Express x16) is a high-speed expansion slot on a motherboard that provides 16 data lanes for connecting devices that require high bandwidth, such as graphics cards.

500

What is Hyper-Threading (SMT)?

Hyper-Threading (HT), known more generally as Simultaneous Multithreading (SMT), is a CPU technology that allows a single physical processor core to function as two logical cores, enabling it to process multiple threads at the same time.

500

what is blue screen of death?

The Blue Screen of Death (BSOD) is an error screen displayed by the Microsoft Windows when the system encounters a critical error that it cannot recover from, causing the computer to stop (crash) to prevent damage or data loss.

500

This is a networking device that connects different networks together and directs data between them, usually between a local network (LAN) and the internet (WAN).
