Protocols

Question 1

Protocols

Answer 1

• The format or structure of the message
• The process by which networking devices share information about pathways to other networks
• How and when error and system messages are passed between devices
• The setting up and termination if data transfer sessions

Question 2

Protocol Suites and Industry Standards

Answer 2

• Institute of Electrical & Electronics Engineers (IEEE)
• Internet Engineering Task Force (IETF)

Question 3

Interaction of Protocols

Answer 3

Hypertext Transfer Protocol > Transmission Control Protocol > Internet Protocol > Ethernet

Question 4

Hypertext Transfer Protocol (HTTP)

Answer 4

• A common protocol that governs the way that a web server and a web client interact
• Defines the content and formatting of the requests and responses exchanged between the client and server
• Both the client and the web server software implement HTTP as part kf the application
• Relies on the other protocols to govern how the messages are transported between client and server

Question 5

Transmission Control Protocol (TCP

Answer 5

• Transport protocol that manages the individual conversations between web servers and web clients
• Divides the HTTP messages into smaller pieces, called segments, to be sent to the destination client
• Responsible for controlling the size and rate at which messages are exchanged between the server and the client

Question 6

Internet Protocol (IP)

Answer 6

Responsible for taking the formatted segments from TCP, encapsulating them into packets, assigning the appropriate addresses, and selecting the best path to the destination host

Question 7

Network Access Protocols

Answer 7

1. Data-link management protocols
2. Physical media standards and protocols

Question 8

Data- link management protocols

Answer 8

Takes the packets from IP and format them to be transmitted over the media

Question 9

Physical media standards and protocols

Answer 9

Governs how the signals are sent over the media and how they are interpreted by the receiving clients. Transceivers on the network interface cards implement the appropriate standards for the media that is being used.
