Hardware Flashcards
The main circuit board in the pc.
Includes various components.
Provides connectivity for inter grated and add-on components.
Motherboard
One or more chips embedded onto the motherboard that provides a variety of functions for the computer.
Chipsets
The chip connected directly to the CPU and responsible for the task that require the highest levels of performance.
Northbridge
The second of the two main chips. Implements the slower capabilities of the motherboard.
Not connected directly to the CPU but instead used to interact with I/O devices
Southbridge
The size and shape of the motherboard as well as describing the power supply and case that can be used.
Form Factor
Is the area that stores the bios configuration information.
CMOS
The PC component that converts AC wall voltage to the various DC voltages required by the computer components
Power Supply
The brains of the computer responsible for controlling activities between components and processing all the data on behalf of the hardware and software
CPU
Liquid based cooling cases are available and circulate water around the components to increase cooling capabilities.
Liquid Cooling
The term used to describe main system memory for running applications
Random Access Memory
The term used to describe chips on the motherboard and devices that store instructions permanently
Read-Only Memory (ROM)
A scheme that enables the detection of memory errors using either even or odd parity schemes. The use of an additional parity bit is used by both the memory controller and CPU
Parity (Memory Error Recovery)
Permits the computer not only to detect errors in memory but also to correct them.
Error Correcting Code (ECC)
The second permanent storage available on the computer system.
Hard drive
These impact style printer have been used as long as personal computers have been and aren’t as popular but are still in use because of the unique abilities it provides.
- The ability to print multi forms
- The ability to use continuous form paper pulled in via a tractor feed

What are the 6 steps of the laser printer process
- Cleaning
- Conditioning (charge the drum)
- Writing (writer image)
- Developing (transfer toner)
- Transferring (transfer image to the paper)
- Fusing (fuse image to the paper)
In a Inkjet printer what are you checking if nothing prints?
If jobs are making it to queue
Connections and power
If ink cartridges are empty or clogged
In inkjet printer what are we checking if there is poor print quality or stray lines.
If there is clogged print heads, bad paper or dust.
Clogged nozzles or worn out print heads.
Incorrect drivers.
What printer type is most popular due to its inexpensive nature of the printer and paper used?
Ink Jet
What printer type provides the ability to print on multi-part forms and continuous feed paper.
Dot Matrix
In what phase of the laser printing process is the ink toner melted to the paper using the fusing assembly heated up to 350 degrees?
Fusing
In what phase of the process is the paper given a positive charge in order to attract the negatively charged toner from the EP drum?
Transferring
True or False Laser printers provide the most cost effective printer type with low maintenance requirements?
False. Laser printers are more expensive up front.
What are the two most common physical connection types for printer today?
USB Universal Serial Bus
NIC Network Interface Controller or Ethernet Port
What term is used to describe a printer with the ability to connect directly to a network?
Network-interface
What acronym is used to describe a scanner technology that allows text to be digitized providing the ability to search text.
OCR Optical Character Recognition is used when scanning documents so that those documents can be search.
What type of printer is used to create three-dimensional objects without using paper?
