Data Communications Module 4
Question and answer 100% correct
station - correct answer is simply an endpoint where subscribers gain access
to the circuit.
node - correct answer A station is sometimes called a
node - correct answer is the location of computers, computer terminals,
workstations, and other digital computing equipment.
Data communication circuits - correct answer utilize electronic
communications equipment and facilities to interconnect digital computer
equipment.
Communications facilities - correct answer are physical means of
interconnecting stations within a data communications system and can include
virtually any type of physical transmission media or wireless radio system in
existence
Public Telephone Networks (PTN), Public Data Networks (PDN) - correct
answer Communications facilities are provided to data communications users
through
opposite directrion - correct answer , bidirectional transmission is possible by
providing a duplicate set of circuit components in the
Source - correct answer generates data and could be a mainframe computer,
personal computer, workstation, or virtually any other piece of digital
equipment
, Transmitter - correct answer encodes the source information and converts it
to a different form, allowing it to be more efficiently propagated through the
transmission medium.
Transmission medium - correct answer carries the encoded signals from the
transmitter to the receiver
Receiver - correct answer converts the encoded signals received from the
transmission medium back to their original form
Destination - correct answer Like the source, the ________ could be a
mainframe computer, personal computer, workstation, or virtually any other
piece of digital equipment
parallel by bit/serial by character - correct answer , each bit position (A0 to
A3) has its own transmission line. Consequently, all four bits can be
transmitted simultaneously during the time of a single clock pulse (TC)
serial by bit - correct answer is a single transmission line and, thus, only one
bit can be transmitted at a time. Consequently, it requires four clock pulses
(4TC) to transmit the entire four-bit code.
parallel transmission - correct answer is used for short-distance data
communications and within a computer
serial transmission - correct answer is used for long-distance data
communications
