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.
Which types of data transmission are being described:
Data is sent 2 bit at a time in both directions, but not at the same time
Serial Simplex
Serial Half-Duplex
Parallel Full-Duplex
Parallel Half-Duplex
Imagine this is the payload for a message:
1110100100100
1001011010001
What would be the value stored in the trailer part of the packet? (Given Cyclic Redundancy Check method is used),
