6th Class Computers Science Networking Network Protocol

     Network Protocol

Protocol is a set of rules that allows two computers on the network to communicate and transfer data between them. Protocols generally implemented by software, hardware, or a combination of the both.    

  The network protocol plays the/allowing roles: v  Identify the corrupt messages using error checker.

• While receiving messages, indicates the receiving devices.
• While sending messages, indicates the sending devices.
• To compress the data transmitted through the network, the method data compression is used.  

  Some of the important networking protocols are:

• Net BIOS Enhanced User Interface (NetBEUI): NetBEUI is a fast efficient protocol that is used on smaller Microsoft networks.
• NW Link: NW Link is faster than TCP/IP but slower than the NetBEUI.
• Apple Talk: AppleTalk is used to communicate with the Apple Macintosh computers.  
• Transmission Control Protocol/Internet Protocol (TCP/IP): TCP/IP is the most popular network protocol that is supported by most of the operating systems.    

 A network is a set of inter connected devices, such as computers and printers. Which of the following are the roles of network protocol?

(A) Identify the corrupt message             

(B) Check error message

(C) Compress the transmit data                

(D) All of these

(E) None of these  

Answer: (D)

Explanation

Correct Option:

(A) Network protocol identifies the corrupt message

(B) Network protocol checks error message.

(C) Network protocol compresses the transmit data.

Incorrect Options:

Rest of the option is incorrect.
