Standards and Concepts Review

What is the purpose of the Application layer of the TCP/IP model?

• The Application layer defines how applications interact with a network.

• The Application layer manages the routing of data packets.

• The Application layer is responsible for error detection and correction.

• The Application layer handles the physical transmission of data.

What is the purpose of the Transport layer of the TCP/IP model?

• The Transport layer ensures a reliable data transfer from a source to a destination.

• The Transport layer is responsible for assigning IP addresses to devices.

• The Transport layer encrypts all data before transmission.

• The Transport layer manages the physical connection between devices.

What is the purpose of the Internet layer of the TCP/IP model?

• The Internet layer handles addressing, fragmenting, and routing data packets from source to destination.

• The Internet layer is responsible for encrypting data for secure transmission.

• The Internet layer manages user authentication and access control.

• The Internet layer provides end-to-end error correction and flow control.

What is the purpose of the Network layer of the TCP/IP model?

• The Network layer defines the data link and physical aspects of data traveling from a source to a destination.

• The Network layer is responsible for encrypting and decrypting data for secure communication.

• The Network layer manages user authentication and access control.

• The Network layer handles application-specific protocols such as HTTP and FTP.

What is the purpose of the Application layer of the OSI model?

• The Application layer defines how applications interact with a network

• It manages the physical transmission of data over the network

• It is responsible for error detection and correction

• It handles routing of data between devices

What is the purpose of the Presentation layer of the OSI model?

• The Presentation layer manages formatting and encrypting data

• The Presentation layer routes data between devices

• The Presentation layer establishes end-to-end connections

• The Presentation layer handles error detection and correction

What is the purpose of the Session layer of the OSI model?

• The Session layer establishes and terminates communication between a source and a destination

• The Session layer is responsible for routing packets across networks

• The Session layer encrypts and decrypts data for secure transmission

• The Session layer handles error detection and correction at the physical level

What is the purpose of the Transport layer of the OSI model?

• The Transport layer breaks data into segments and is responsible for checking to see if any errors occur in a data transmission

• The Transport layer is responsible for routing packets between devices on different networks

• The Transport layer encrypts data for secure transmission across the network

• The Transport layer manages the physical connection between devices

What is the purpose of the Network layer of the OSI model?

• The Network layer breaks down data into segments, then packets. The packets are tagged with the source and destination IP address and routed to the destination

• The Network layer encrypts data for secure transmission over the network.

• The Network layer is responsible for establishing and terminating connections between two devices.

• The Network layer converts data into electrical signals for transmission over physical media.

What is the purpose of the Data Link layer of the OSI model?

• The Data Link layer frames data and performs MAC addressing

• It routes packets between networks

• It encrypts data for secure transmission

• It manages end-to-end communication sessions
