IT Vocab 1 Flashcards
A device that can be connected to a computer or network that scans paper documents and converts them into digital files
Scanner
A connector, identified by its blue color and three rows of pins, that is used to connect older monitors to a computer
Video Graphics Array (VGA) connector
Heat sinks and fans that keep computer components, especially the CPU, from overheating
Cooling system
The most important pat of any modern computer system that controls the other parts of the computer
Central Processing Unit (CPU)
A large, flat computer component that connects the important components of the computer, such as the CPU, RAM, and the BIOS chip. It also has power and other communications connections
Motherboard
A three step cycle (fetch, decode, and, execute) that processors use to execute instructions
The Fetch-Execute cycle
A unit that supplies electricity to the motherboard and other computer components
Power Supply
A family of processors manufactured by Intel and AMD that use a common instruction set, or list of commands, that the processor can execute
x86 processors
A cooling system composed of a liquid heat sink, internal liquid pump, a fan, and a radiator that all actively pump cooled liquid in and out with no help from an outside pumping system.
Active liquid heat sink
A connector, typically white with three rows of eight pins, designed to connect digital monitors to a computer
Digital visual interface (DVI)
A display device that allows a user to interact with a computer by touching, tapping, and swiping areas on the screen
Touch screen
a connector used to connect a computer to an HDMI monitor or TV
High Definition Media Interface (HDMI)
A printer that uses electrical charges and heat to fuse tiny plastic particles (called toner) to the paper
Laser printer
A common interface used to connect peripherals, such as mice, keyboards, printers, and digital cameras to a computer
Universal Serial Bus (USB)
A common method of cooling that uses fans to move hot air out of a system
Air cooling
A printer that sprays small dots of ink from an ink reservoir onto a sheet of paper
Inkjet printer
A family of processors most often used in smartphones due to its lower power requirements. This is accomplished by reducing the processors’ instruction set
Advanced RISC Machines (ARM)
an event in which two objects with different charge levels come together resulting in an electrostatic shock
Electrostatic discharge
A computer component that attaches to a chip (like a CPU) that disperses heat and prevents overheating
Heat sink
an additional computer processor that provides graphics processing, providing better performance by relieving the CPU of this duty
Graphics Processing Unit (GPU)
A liquid-cooled system that places a water-cooled heat exchanger near a heat source. The exchanger then removes the heat, reducing the air temperature
Water cooling
A component, sometimes built into and sometimes plugged into the motherboard, that provides network connectivity
Network Interface Card (NIC)
The main memory of a computer that can be quickly accessed by the CPU and where the computer stores data and instructions that it is actively using.
Random Access Memory (RAM)
A device, usually external to a computer, that is plugged into a computer’s communication port or is connected wirelessly. Common peripherals are keyboards, mice, speakers, monitors, and printers
Peripheral
A circuit board that connects to a computer’s motherboard, giving it additional power or functionality
Expansion card
An advanced system of cooling where liquid coolant is in direct contact with the CPU offering a high heat transfer that quickly reduces the temperature of the CPU’s surface
Immersion cooling
