Module 1 Devices Setup and Installs Flashcards
What is OSHA?
OSHA is a prime example of safety regulations for US-based operations.
Most PC circuits are low voltage/ low current however there are noticeable exceptions. What are they?
Power Supply, CRT monitors, LCD display inverter card, Laser printer.
These are also known as Black Box.
What is ESD? (Electrostatic discharge)
A situation that occurs when electrons rush from one statically charged body to another with an unequal charge, following the path of least resistance.
What can you do when handling components?
- Self-grounding - The act of touching a grounded object before touching electrical equipment.
- Using ESD wrist or leg straps.
- Using ESD service mats or smocks.
- Using antistatic bags.
System Case Types?
- Full tower - houses ATX motherboard.
- Mid tower - houses either ATX or micro ATX motherboard.
- Mini tower - houses mini ITX motherboard.
- Small form factor (SFF) - Small motherboards. (Mini ITX, PICO ITX and FEMTO ITX)
What is a Field replacement unit (FRU)
An adapter or other component that can be replaced by a technician on-site.
Main Guidelines for PC Disassembly
- Back up all data stored on the internal drive(S).
- Clean area to work in.
- Gather all necessary tools and equipment.
- All devices powered off / unplugged from main power.
- Hold power button down after PC has been unplugged to drain all power out.
- Take antistatic precautions.
Motherboards provide the basic function for all the computers hardware, including…..
The processor, RAM, Firmware, and expansion cards
What does PGA and LGA stand for?
PGA - Pen grid array
LGA - Land grid array
What does a Chipset do?
Chipsets provides communications between different components by implementing various controllers.
True or false? Are chipsets upgradable?
False - Chipsets are not upgradable.
What is RAM?
Random access memory (RAM) - The principle storage space for the computer data and program instructions. Volatile memory that loses data when there is no power.
What is the CMOS battery used for?
CMOS battery is the battery that powers the chipset that keeps track of the time and date. (Real time clock (RTC) / Clock battery).
Bus Architecture
What is a Bus?
Connections between components on the motherboard and peripheral devices attached to the computer.
Bus Architecture
What is a Tracer?
Wires etched on to the motherboard to provide electrical pathways.
What is the Local Bus?
The internal bus that connects core components directly to the processor, resulting in the highest possible data speed as required by components such as the video display.
What is the Expansion Bus?
The external bus that allows additional components to be connected to the computer. Can be internal or external.
True or False? The Expansion Bus is only external?
False, Can be internal or external.
What is an Expansion slots
Connection slots on the motherboard in which adapter cards can be installed to extend the range of functions the computer can perform.
What is a Riser Card?
A space saving feature of some motherboards that puts the PC’s expansion slots on a separate board installed at a right angle to the main board, allowing system components to fit within a slimline case.
What does the System Clock do?
The computers timing mechanism that syncs the operation of all parts of the computer and provides the basic timing signals of the CPU.
System Clock speed measurements?
- Megahertz (MHz) - 1 million cycles per second.
- Gigahertz (GHz) - 1 Billion cycles per second.
What does PCIe stand for?
Peripheral component interconnect express (PCIe)
What is the PCIe bus?
Peripheral component interconnect express (PCIe) bus - Serial communication with point to point links between I/O controller and devices.
