FUNDAMENTALS OF COMMUNICATION Flashcards
is raw facts and figures.
They have very little meaning until they are
sorted or they are used to make calculations.
DATA
The process of sorting or calculating data
DATA PROCESSING
The result of data processing
INFORMATION
is a symbolic, transactional process, or
the process of creating and sharing meaning.
Communication
Electronic transfer of data from one location to another
Enables an information system to deliver information
Data communication
Amount of data that can be transferred from one point to another in a
certain time period
Bandwidth
Loss of power in a signal as it travels from the sending device to the
receiving device
Attenuation
Multiple pieces of data are sent simultaneously to increase the
transmission rate
Broadband data transmission
Voice-grade transmission channel capable of transmitting a
maximum of 56,000 bps, so only a limited amount of information
can be transferred
Narrowband
Rules that govern data communication, including error detection,
message length, and transmission speed
Protocols
It refers to electric device and system for
transferring data or information from one
place to another.
Communication Hardware
an electronic device that allows
computer talk to each other over
telephone line
MODEM
Computer can communicate directly
with each other without MODEM
CABLE
is commonly used by cable operators, telephone companies, and internet
providers around the world to convey data,
video, and voice communications to
customers.
Coaxial cable
Twisted pair cabling is a type of
wiring in which two
conductors of a single circuit
are twisted together for the
purposes of improving
electromagnetic
compatibility.
UTP - Unshielded
Twisted Pair cable
used most often as a means to
transmit light between the two
ends of the fiber.
Fiber Optics
Modem with fax
capability that enables
you to rend signals
directly from your
computer to someone
else fax machine or
computer
FAXMODEM
device that forwards data
packets between computer
networks, creating an
overlay interworks.It is
connected to two or more
data
ROUTER
The transfer of information between to
or more points that are not connected
by an electrical conductor
WIRELESS TECHNOLOGY
Standard for exchanging
data over a short
distance ( using short
wave length radio
transmission )
BLUETOOTH
Technology that allows
computing devices to
communicate with a short
range wireless signal
INFRARED
It allows an
electronic device
to exchange data
or connection to
the internet
wireless
Wi-Fi * (Wireless Fidelity)
