Explanation / Answer
1.Describe the purpose of an RPC.
A) Remote Procedure Call (RPC) provides a different pattern for accessing network services.It provides Instead of accessing remote services by sending and receiving messages, a client invokes services by making a local procedure call. The local procedure hides the details of the network communication.
The main purpose of RPC is to hide the existence of the network from a program.RPC is especially well suited for client-server (e.g., query-response) interaction in which the flow of control alternates between the client and server. Conceptually, the client and server do not both execute at the same time. Instead, the thread of execution jumps from the caller to the callee and then back again.
2. When two computers request a connection, what are the four primary actions that the Session Layer takes?
A)the two computers connecting through 7layers ,in this Layer 5, the session layer, allows two applications on different computers to open, use, and close a connection called a session. The session layer is responsible for managing this dialog. It performs name-recognition and other functions, such as security, that are needed to allow two applications to communicate over the network.
It performs the following four primary actions
3. List a few examples of protocols that the Session Layer may use and what they’d be used for.
4. Briefly describe the process of Network Address Translation.
A) Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. The main use of NAT is to limit the number of public IP addresses an organization or company must use.
5. Dialog Control is the main function of the Session Layer. Describe how Dialog Control works.
a) Dialog control is the main function of session layer that determines which device will communicate first and the amount of data that will be sent.
This layer works as allows two systems to start communication with each other in half-duplex(allowing the transmission of signals in both directions but not simultaneously.) or full-duplex(allowing to the transmission of data in two directions simultaneously).
6. What is SQL and what is it used for?
A) SQL Structured Query Language is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS).
SQL consists of a data definition language, data manipulation language, and a data control language. The scope of SQL includes data insert, query, update and delete, schema creation and modification, and data access control.
