Data Tranmission

A method of data transmission in which a message is broken up into a number of packets.

What is the process called

• Message Splitting

• Packet Splitting

• Message Switching

• Packet Switching

Data can be broken up into multiple data packets.

Each packet can be sent along a different ______ to the destination.

Fill in the blank.

• Method

• Route

• Path

• error 404

One disadvantage of packet switching is that data needs to be (a)   when it reaches the destination.

A typical packet is split up into

• Header

• Body

• Payload

• Trailer

The header of a packet consists of :

• Sender IP Address

• Contents of the packet

• Sequence Number of the packet

• Receive IP Address

• Bits used for error detection

The following is a statement regarding the Cyclic Redundancy Check.

The sending computer will add up all the 1-bits in the payload and store it as a (a)   value in the trailer before it is sent.

Serial data transmission occurs when data is sent (a)   BIT AT A TIME over a single wire/channel.

Parallel data transmission occurs when SEVERAL BITS OF DATA are sent down at the (a)   time

Half-duplex mode occurs when data can be sent in BOTH DIRECTIONS AT THE SAME TIME

• True

• False

Simplex mode occurs when data can be sent in (a)   DIRECTION ONLY.
