Cards

Term
This type of electricity can cause computer components to malfunction. To avoid problems, users should take precautions such as grounding themselves before working in the system.
Definition
Static
Term
This signal is continuous between two fixed settings; it can take on an infinite number of intermediary values. ______________________
Definition
Analog signal
Term
This signal has two fixed states. It is either on or off. It can take on only two numeric values. _____________________
Definition
Digital Signal
Term
Electricity flows readily through this type of substance because it offers less resistance to current flow.
Definition
Conductors
Term
Circle the correct answer.
Most metal / organic materials serve as good conductors, but metal / organic materials serve as better insulators.
Definition
Most metal materials serve as good conductors, but organic materials serve as better insulators.
Term
This type of material conducts less electricity than a conductor but has more natural conductivity than an insulator.
Definition
Semiconductor
Term
Provide a few specific examples of materials with the following electrical properties:
a Good conductors ______________________________________
b Good insulators _______________________________________
c Good semiconductors _________________________
Definition
Conductors: gold, silver, aluminum, iron, mercury, carbon. Insulators: Wood, glass, Rubber. Semiconductors: Germanium, Silicon.
Term
This electrical device was invented in 1947 at Bell Labs and revolutionized digital computers. It can also amplify a signal or act as a switch to open or close a circuit.
Definition
Transistor
Term
These are the leads on a discrete transistor.
Definition
Emitter, Collector, Base
Term
Transistors acting in conjunction with other transistors create these miniature circuits that translate electrical flow into meaningful information.
Definition
Logic gates
Term
This term refers to the microchip that is etched onto the silicon wafer.
Definition
Die
Term
Pin Grid Array style processors fit into this type of connector on the motherboard.
Definition
ZIF socket
Term
Determine if the statements are true or false. If false, correct the statement.
It is not necessary to match the processor with a compatible socket or slot on the
motherboard. Intel processors are designed to be interchangeable with AMD processors.
Definition
False, there is a different number of pins between the two.
Term
ESD stands for ?
Definition
Electrostatic Discharge - The unintended movement of electrons from one body to another.
Term
DIP stands for ?
Definition
Dual Inline Package - A type of solid state device (computer chip) housed in a rectangular casing with two rows of connecting pins.
Term
SECC stands for ?
Definition
Single Edge Contact Cartridge - A computer chip developed by Intel that closely resembles an expansion card, and fits into a slot on the motherboard.
Term
PGA stands for ?
Definition
Pin Grid Array - A type of computer chip package in which the conducting pins are
located on the bottom in a grid of squares.
Term
Zif stands for ?
Definition
Zero Insertion Force - socket on the motherboard for holding the CPU.
