15 Questions
What is the purpose of encapsulation in protocols?
To reduce duplication of effort
Which layer of the OSI model is responsible for hop-to-hop delivery?
Network layer
How does the TCP/IP protocol suite differ from the OSI model in terms of layers?
TCP/IP has fewer layers than the OSI model
What is the main difference between the transport layer and the network layer in the OSI model?
The transport layer provides hop-to-hop delivery, while the network layer provides end-to-end delivery
Which functions form the basis of all protocols?
Encapsulation and ordered delivery
Why do some protocols not have all protocol functions?
To reduce duplication of effort
What type of addresses are used in an internet employing the TCP/IP protocols?
Physical, logical, port, and specific
What does the Logical Address represent in TCP/IP?
Generated by the CPU while the program is running
How are most local-area networks' physical addresses written?
As 12 hexadecimal digits separated by a colon or dash
What is used to find the physical address of the next hop in the network layer?
Routing table
What protocol finds the physical address of a router that corresponds to its logical address?
Address Resolution Protocol (ARP)
What does the Logical Address represent in TCP/IP?
Generated by the CPU while the program is running
What do most local-area networks use as a physical address format?
48-bits (6-byte) physical address written as 12 hexadecimal digits
What represents the Logical Address in computer networking?
'Virtual' generated by CPU during program execution
Which protocol is used to find the physical address of a router corresponding to its logical address?
'Address Resolution Protocol (ARP)'
Test your knowledge on the functions of protocols and the seven layers of the OSI model, including encapsulation, fragmentation, connection control, ordered delivery, flow control, error control, addressing, multiplexing, and transmission services. Understand the interaction between layers in the OSI model.
