Review on Final Paper

Section-B

Q2. What is a Protocol? Explain TCP/IP model? Compare TCP/IP and OSI.

Ans: Protocol is set of rules for communication (1M).

TCP/IP Model: Application, Transport, Internet, Host-to-Network (NW access layer). (overview of each layer-2M)

Comparison: TCP layers and OSI layer, Diagram only or six difference (2M).

Q3. Briefly explain interprocess communication.

Ans: it is used to communication b/w two process (1M).

Types: Message passing (block & non blocking) and Shared Memory(Just overview-2M)

Mechanism: Pipes, Fifo, Message Queue and Signals(Just overview-2M)

Q4. Diff b/w IPV4 & IPV6.

Ans: Diagram and 4 difference (4M)

          Inter….(1M)

Q5. Computer Network? Benefits? Daily Use

Ans: A network is a group of two or more computer systems linked together. There are many types of computer networks, including the following: LAN, MAN, WAN (1M).

Benefits: (2M):

Networking helps in sharing of hardware. Data Sharing. Helps to enhance connectivity. improve communication. Eases out management of data

Daily Use: E-Bill, Net banking, Digital Library, Social sites, E-Newspaper, Communication through Email etc (2M)

Q6.

Shared Memory:  Definition (1M). Three diagram (0.5 for each)

Semaphore: it is used to synchronized the process(1M)

                      Types and P&V (1.5)

                     

Section-C

7Q. What is socket? How to create for TCP & UDP ? Diff b/w TCP & UDP?

Ans:

Socket: It is used to connect or communication b/w two process. It is a combination of IP address and Port Address (Small description of address-2M).

TCP: Diagram only(2M):

        Server side: Socket(), Bind(), Listen(), Accept(), Read()/Recv()/Sendto()/write(), close().

      Client side: Socket(), Connect(),Read()/Recv()/Sendto()/write(), close().

UDP: Diagram only (2M):

        Server side: Socket(), Bind(),Recv()/Sendto(), close().

       Client side: Socket(),Sendto()/Recv(), close().

Diff b/w tcp and udp (4M)

        At least six difference

8a). Communication Protocol.

Ans: Protocol is a set of rule for communication between two devices. (1M)

Protocol: XNS, SNA, TCP, IP (Diagram/Overview, 1 marks for each protocol=4)

8b). RPC

Ans: Diagram and ten steps (diagram-4, description-1 )

8c) Shell programming

Ans: Definition(1M)

        As your choice/Know (2M)

        Commands/program (2M)

9Q:

Diagram(4M):

Functions with prototype: At least 8 Function (6M)
