Answer:
The purpose of TCP / IP is to provide computers with a method to transmit data to each other. TCP/ IP provides the means for application to send data between computers and for networks to deliver that data to applications on others computers.
Explanation:
The internet control protocol (TCP/ IP, transmission control IP / internet protocol) is the set of protocols used to transport information on the internet and in most private networks. The TCP/IP name leaves two more important protocols of the transport layers (TCP) and the network layer (IP).
Each internet application depends on the communication of data between two or more processes. The most common is that they are two processes, and that their roles are well defined as client and server. The applications under this model ''client-server'', will issue a service request on the client side, and the server will elaborate a response and return it to the client.
To communicate these two processes it is necessary that the data that configure the requirement made by the client, and those that configure the response, produced by the server, can circulate through the network in both directions. The TCP/IP protocol suite resolves this need. For this, IP performs communication between devices, hosts, or nodes of the network, creating virtual paths between them through its fundamental function, which is routing.
Answer:
/30
Explanation:
/ 30 subnet have total two hosts and 419432 subnets. In above example we to connect or install router in two buildings that why /30 subnet is feasible. because this provides two host.
This statement is not true. A table is defined as a collection of related records.
