|
Main functions of the Transport layer ? |
• The transport layer divides the data into pieces and ads a header for the delivery of the network. • Moves data between applications and devices in the network. • Data for different applications is directed to the correct application because each application has a unique port number |
|
|
What simple mechanism is used For checking errors in the transport header ? |
Flow control. Flow control assist the reliability of TCP transmission by adjusting the effective rate of data flow |
|
|
What is time to live ? |
Time to live is it eight bit binary numbers that indicates the remaining life of a packet. TTL is decreased by one each time the packet is sent by a router, When it becomes 0 to Packet drops |
|
|
What does The packet header protocol mean ? |
Protocol is a bit binary value which indicates the data payload the packet is carrying |
|
|
What is the Checksum In packet header? |
Checksum is to protect the packets against data corruption |
|
|
TCP pros |
TCP is very reliable, guarantees data transfer remains in tact, and arrives in the right order. |
|
|
UDP cons |
UDP is only best effort, unreliable, used in application with fast, officiant transmission, such as games |
|
|
Purpose of Subnet mask ? |
To increase managers control over their address space and makes it easier to allocate the address space, and better network performance. |
|
|
What is VLSM ? |
VLSM is subnetting of a subnet |
|
|
What is meant by CIDR notation in relation to subnet |
CIDR are are used to try and conserve address space as IP addresses are running out |
|
|
What is Segmentation ? |
Segmentation is the process of dividing data packets into smaller chunks for sending over the network |
|
|
What is in Encapsulation ? |
Encapsulation is a process of taking data from one protocol and transferring it to another |
