100

The three-step process through which data flows through a computer.

What is Input, Processing, and Output?

100

The main circuit board that enables all internal components in a computer to communicate.

What is the Motherboard (or System Board)?

100

Cooling systems that rely on electrically powered mechanical parts, such as fans.

What is Active Cooling?

100

This blue, 15-pin analog connector with three rows of five pins is the oldest display interface still found on older monitors.

What is VGA (Video Graphics Array)?

100

The temporary system memory that loses all of its stored data as soon as the computer is powered off.

What is RAM?

200

Thin, fragile wafers of silicon and tiny transistors packaged in a robust shell that handle most math operations.

What is a Central Processing Unit (or CPU / Microprocessor)?

200

Units used to measure CPU speed in the 1980s and 1990s, representing millions of cycles per second.

What is Megahertz (MHz)?

200

This internal component converts AC power from a wall outlet into DC power and distributes it to the motherboard and other PC parts.

What is a Power Supply Unit (PSU)?

200

The current standard interface for televisions and computer monitors that carries both high-definition video and audio signals over a single cable.

What is HDMI (High-Definition Multimedia Interface)?

200

The delivery of computing services—including servers, storage, databases, networking, and software—over the Internet instead of running them on local hardware.

What is the Cloud (or Cloud Computing)?

300

The chip manufacturer that holds the largest market share in desktop and laptop CPUs.

What is Intel?

300

Small amounts of super-fast memory embedded directly inside the CPU chip to reduce fetch times from main RAM.

What is Cache (or CPU Cache)?

300

A block of metal affixed to a chip that draws heat away without using moving parts or electricity.

What is a Passive Heat Sink?

300

This modern, reversible USB connector type can be plugged in upside down or right side up without damaging the port.

What is USB Type-C?

300

Unlike a LAN that covers a single building, this type of telecommunication network connects computers across large geographic distances, cities, or continents.

What is a WAN (Wide Area Network)?

400

Other than Intel, this company is the major competitor manufacturing CPUs for desktop and laptop computers.

What is AMD (or Advanced Micro Devices)?

400

The standard unit of measurement used to measure modern CPU speeds in billions of cycles per second.

What is Gigahertz (GHz)?

400

Advanced cooling setup that uses sealed tubing, and a pump to carry heat away from chips to a radiator.

What is Liquid Cooling?

400

An 8-pin rectangular plastic connector with a top release tab used to connect computers to a wired Ethernet network.

What is an RJ-45 connector?

400

Long, thin circuit boards used to install system memory sticks into a desktop motherboard.

What are DIMMs (Dual Inline Memory Modules)?

500

The design company that creates the vast majority of CPUs used in mobile devices like smartphones and tablets.

What is ARM Holdings?

500

The measurement equal to one cycle per second under perfect conditions.

What is 1 Hertz (Hz)?

500

The substance placed between a CPU chip and a heat sink to maximize thermal transfer.

What is Thermal Paste?

500

This near-square USB connector type is commonly found on the device end of full-size peripherals like desktop printers and scanners.

What is USB Type-B?

500

The legacy, built-in motherboard setup firmware that initializes hardware during startup before handing control over to the operating system.

What is BIOS (Basic Input/Output System)?
