I dont know how to do that
Answer:
A) Transmission of letter, message and memos over a communication network
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties. One of the most widely used communication channel or medium is e-mail (electronic mail).
An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send texts and multimedia messages over the internet.
Hence, electronic mail is a transmission of letter, message and memos over a communication network. Some examples of the commonly used electronic mails platform are Yahoo, G-mail, etc.
Answer:
FULL neighbor state.
(FULL/DR or FULL/BDR)
Explanation:
The fact that the routers are neighbors is not enough to guarantee an exchange of link status updates; they must form adjacencies to exchange link status updates. Adjacency is the next step after the process of establishing neighbors. Adjacent routers are routers that go beyond a simple Greeting exchange and act in the database exchange process. To reduce the amount of information exchange in a given segment, OSPF selects a router as a designated router (DR) and a router as a designated backup router (BDR) in each multiple access segment. The BDR is chosen as the backup mechanism in case the DR fails. The idea behind this is that routers have a central point of contact for the exchange of information. In order to verify if two routers have established an adjacency, you can use the command: show ip ospf neighbor.
Here is an example:
R1#show ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface

Answer:
The network layer is the layer is the layer 3 of the seven layer Open System Interconnect (OSI model) which functions as packet forwarder for the intermediate routers by implementing technologies used for switching that provides virtual circuits' logical path
The function of the network layer includes;
1) Routing and forwarding of packets to destination which enables connectionless communication
2) Enabling internetworking
3) Hierarchical host (IP) addressing
4) Sequencing of packets
5) Handling of errors
6) Control of network congestion to prevent the collapse of the network
