Topic 5 Flashcards
refers to the mechanism of transferring of data between two devices connected over a network.
Transmission Mode
It is also called Communication Mode
Transmission Mode
In this type of transmission mode, data can be sent only in one direction i.e. communication is unidirectional.
Simplex Mode
We cannot send a message back to the sender.
Simplex Mode
Unidirectional communication is done in Simplex Systems where we just need to send a command/signal, and do not expect any response back.
Simplex Mode
means that data can be transmitted in both directions on a signal carrier, but not at the same time
Half-duplex Mode
we can send data in both the directions as it is bidirectional at the same time in other words, data can be sent in both directions simultaneously.
Full-Duplex Mode
are used to connect and transfer data and information between computers, routers, switches and storage area networks.
Network Cables
are essentially the carrier or media through which data flows.
Cables
The most commonly used types of network cables are dominated by what is referred to as ______
Twisted Pair Cable
In local area networks, ___________ is by far the most commonly used type of cable.
Twisted pair cable
What are the common ethernet network cable?
Straight and crossover cables
This Ethernet network cable is made of 4 pair high performance cable that consists twisted pair conductors that used for data transmission. Both end of cable is called ________
RJ45 connector.
The cable can be categorized as _______________
Cat 5, Cat 5e, Cat 6 cable.
Cat 5 UTP cable can support
10/100 Mbps Ethernet network
Cat 5e and Cat 6 UTP cable can support Ethernet network running at __________________________
10/100/1000 Mbps
The continuous signals in wave form is called ________
Analog signals
What are the examples of analog signals
Light waves
Sound waves
Radio Waves
The transfer of data from one place to another place in the form of analog signals or continuous waves is called ________
Analog Data Transmission
What are the examples of Analog Data Transmission
*Transmission through telephone lines
*Transmission through microwave system
*Transmission through Satellite
The transfer of data from one place to another place in the form of digital signals is called __________________
Digital Data Transmission
is used on both sides.
Modem
is combination of Mo(Modulation) and Dem(Demodulation)
Modem
Digital to Analog
Modulation
Analog to Digital
Demodulation
When the devices are same, then __________ is used
Crossover cable
When devices are different, _________ is used.
Straight cable
