Protocol
Procedures and rules use to send and receive data between computers.
- Method of sending and receiving data
- Process used to handle communication errors
Conditions required for communication are organized in procedures for correct transfer of information.
PS/2
An IBM series of personal computers which established a number of standards for connecting external
devices such as keyboards and monitors.
RAM
Random Access Memory. A hardware component of your notebook that holds binary information
(both program and data) as long as it has the proper power applied to it.
RAM Module
A printed circuit card with memory and associated circuitry which allows the user to add additional
memory to the computer without special tools.
Reset
The act of reloading the operating system. A reset erases all information stored in RAM.
Restart
See Reset.
Resume
To proceed after interruption. In your notebook this refers to returning to active operation after having
been in one of the suspension states.
ROM
Read Only Memory. A form of memory in which information is stored by physically altering the material.
Data stored in this way can not be changed by your notebook and does not require power to maintain
it.
SDRAM
Synchronous Dynamic Random Access Memory.
Serial Port
A connection to another device through which data is transferred one bit at a time on a single wire
with any other wires only for control of the device not for transfer of data.
Shadow RAM
A technique of copying data or applications stored in ROM (Read Only Memory) into RAM (Random
Access Memory) for access during actual operation. RAM is much faster to access than ROM, however
ROM contents are not lost when power is removed. Shadowing allows permanently stored information
to be rapidly accessed.
