This address belongs to class C, so 8 bits are reserved for the host ID. 24 bits are reserved for network ID.

An IPv6 address is 128 bits long, which has 2^128 address space.

128.64.0.0 is correct IPv4 address because IPv4 is a standard numbering system that uses four integers from 0 to 255. The IP address is a group of numbers that identify user system on the network.

121.12.12.248 address belongs the class A because the first octet value of this address lies between 0 and 127.

The term WAN stands for Wide Area Network.

A loopback address is a special IP address whose IP address is between 127.0.0.1 to 127.255.255.255. It is reserved for loopback. It doesn't require a physical connection to a network.

In class C only, 8 bits are reserved for the host ID, and 24 bits are reserved for network ID.

A microwave link cannot be used as a medium for 802.3 ethernets, because a microwave link is a transmission network that utilizes a beam of radio waves in the microwave frequency spectrum to relay video, audio, or data between two places.

There are only two IP versions are avilable in the present: IP version 4 (IPv4) and IP version 6 (IPv6).

The term IANA stands for Internet Assigned Numbers Authority.

In Pure Aloha, Efficiency = 18.4%
Usable bandwidth for 18.2 kbps = 18.2 * 0.18 = 3.276 kbps
Therefore, the maximum throughput of Pure Aloha
= 1/2e * 3.276
= (18.4 * 3.276) / 100
= 0.6027

The hamming codes is an error recovery technique that can be used to detect and correct the errors. It was developed by R.W. Hamming.

The host to host layer conforms the transport layer of the OSI model. This layer is responsible for the final correspondence and error-free distribution of data.
