BMET 108 Quiz 1
Expansion Bus
Allows for the addition of new hardware to a computer system
Storage
Allows for the storage of inputs and/or their resulting outputs as well as the transfer of information
Four steps of processes of computing
Input, Processing, Output, Storage
Zero Insertion Force (ZIF)
Makes installation of a CPU easier and prevents CPU damage at installation
virtualization
Running more than one computer system within a single unit using the same hardware
Cache
SRAM that pre-loads as many instructions as possible and keeps copies of frequently used instructions
Parity storage operation
Stores either a 1 or a 0 in the parity bit depending on if there was an odd or even number of 1s
Four basic computer componants
System Unit, CPU, Random Access Memory (RAM), Hard Drive
Input
Take an input in any form from the outside world (keyboard, microphone, mouse, etc...)
Multicore processing
Technique using more than one CPU on a chip to operate a computer.
Device drivers
Tells the operating system how to interact with any expansion card
Before Video Test
Test CPU, RAM, video card; displayed with beeps
Sag protection
Uninterruptable Power Supply (UPS) devices supply AC power during power sags or outages through the use of a battery backup system
HD15 (VGA)
Used to connect a video device such as a monitor analog signal = degraded signal quality over longer distances
Hot - Swappable
can be inserted or removed without a system unit restart
HDMI
carries both sound and video on one cable
Static RAM
doesn't need to be refreshed, faster than DRAM, more expensive, made of MOSFETS and flip flops
USB 3.0
maximum speed of 5Gbps (typically differentiated by a blue insert)
ATX
most common form factor
Dynamic RAM
must be refreshed, less expensive, made of MOSFETS and capacitors
ATX standard
provides +5, -5, +12, -12, and +3V
Clock Chip
provides a signal to the CPU telling it that it is time to read an instruction and perform an operation and determines the speed at which the CPU performs tasks
Partitioning
subdividing a physical drive into one or more units
Device Driver
File that tells the operating system how to interface with a piece of hardware
Micro ATX
Fits into standard ATX cases as well as smaller specialized micro ATX cases
Hard drives three basic parts
Individual discs called platters Read/Write heads An actuator arm controlled by a motor
wait state
A time where the CPU pipeline is stalled waiting on RAM or data or instruction
RG-6
Commonly used for cable television and internet cable modern connections
DisplayPort
Connect a video source to a display device, but can also carry audio, USB or other forms of data
Latency
Delay in response time to a request to read/write data from/to RAM
RJ-45
Ethernet connector/Jack
Standard set of peripherals
Monitor Keyboard Mouse Speakers Printer
Processing
Performing an action with the input
2 connections required for a standard SATA HDD
Power Cable SATA controller cable for data Can be used for other non-hard drive components such as optical drives
Basic Input Output services (BIOS)
Programs that instruct the CPU how to perform various basic functions such as booting and also provides instructions to the CPU on how to communicate with the basic hardware of the system
Output
Providing the result of an action performed with an input back to the outside world
Multi-Channel Architecture
RAM is required to be installed in matched sets a. Technology b. Capacity c. Speed d. Latency On boards with 4 or more slots, RAM must be put into paired slots that are usually color coded
PCI Express (PCIe)
The latest, fastest, and most popular expansion bus in use today.
