Answer 1

The binary equivalent of the internet address 127.7.55.8 is:

e)01111111.00000111.00110111.00010000

Explaination:

To know the binary equivalent of the given internet address we have to convert the decimal numbers to binary numbers. The conversion of the decimal numbers to binary is given below.

22) The answer is 4 and 5

Explaination:

The TCP/IP protocols are primarily concerned with the Network layer and Transport layer.

The first layer is Application layer.

The second layer is Presentation layer

The third layer is session layer

The fourth layer is Transport layer

and the fifth layer is Network layer

The TCP/IP protocol is concerned with transport layer and the network layer.

So the answer is 4 and 5.

23) d)Both a and b

Explaination:

The protocol field in an IP datagram performing at a FTP transfer will most likely contain a value corresponding to Transport Control Protocol that is TCP and Internet Protocol IP.

24) FTP (File transfer protocol)

The protocol used for transferring files across the network is File Transferring Protocol.

Explaination:

FTP is a standard file transferring protocol that uses TCP/IP datagram to transfer files from one host to another host.
