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.
RAM
Random Access Memory. A hardware component of
your notebook/Tablet PC 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/Tablet
PC 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 infor-
mation is stored by physically altering the material. Data
stored in this way can not be changed by your notebook/
Tablet PC 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.
Shared key authentication
One of the network authentication types for wireless
LAN. Upon authentication, the access point checks
whether the same network key is set to the client. If the
client uses a wrong network key or the network key itself
is not set, authentication is unsuccessful, allowing no
communications with the access point.
SMART
Self-Monitoring, Analysis and Reporting Technology
(SMART) is an emerging technology that provides near-
term failure predictions for hard drives. When SMART
is enabled the hard drive monitors pre-determined drive
attributes that are susceptible to degradation over time.
If a failure is likely to occur, SMART makes a status
report available so that the notebook/Tablet PC can
prompt the user to back up the data on the drive. Natu-
rally not all failures are predictable. SMART predict-
ability is limited to those attributes which the drive can
self-monitor. In those cases where SMART can give
advance warning, a considerable amount of precious
data can be saved.
SRAM
Static random access memory. A specific technology of
making RAM which does not require periodic data
refreshing.
SSID
Service Set Identifier
Specifies which network you are joining. Some systems
allow you to specify any SSID as an option so you can
join any network.
Standby
To make inoperative for a period of time. Your note-
book/Tablet PC uses various suspension states to reduce
power consumption and prolong the charge of your
battery.
Status Indicator
A display which reports the condition of some portion
of your hardware. On your notebook/Tablet PC this is
an LCD screen just above the keyboard.
Stereo (audio)
A system using two channels to process sound from two
different sources.
Subnet mask
TCP-IP network is controlled by being divided into
multiple smaller networks (subnets). IP address consists
of the subnet address and the address of each computer.
Subnet mask defines how many bits of IP address
comprise the subnet address. The same value shall be set
among computers communicating with each other.
SVGA
Super VGA.
S-Video
Super Video. A component video system for driving a
TV or computer monitor.
System Clock
An oscillator of fixed precise frequency which synchro-
nizes the operation of the system and is counted to
provide time of day and date.
TCP/IP
