Term
| What is the goal of the OSI model? |
|
Definition
| Operating systems (OS) independence: to allow computers with any OS to communicate |
|
|
Term

|
Term
| What does each layer interact with? |
|
Definition
|
|
Term
| What does the Application layer interact with? |
|
Definition
-Presentation layer
-End user |
|
|
Term
| What is the purpose of the presentation layer? |
|
Definition
| To act as a translator and determine how to format and present data |
|
|
Term
| What is the purpose of the Session layer? |
|
Definition
| To establish, maintain, and terminate sessions and ensure the data from different applications are kept separate |
|
|
Term
| Term: Lasting connection between two networking devices |
|

|
Term
| What are the three modes of transmission used by computers? |
|
Definition
-Simplex
-Half-duplex
-Full-duplex |
|
|
Term
| Term: Mode of transmission in which data can only be sent one way (least common) |
|
Definition
|
|
Term
| Term: Mode of transmission in which data can be sent both ways but only one at a time |
|
Definition
|
|
Term

|
Definition
|
|
Term
| What is the purpose of the transport layer? |
|
Definition
| To handle flow control, reliability, and error checking |
|
|
Term
| How does the transport layer work? |
|
Definition
| It divides the data into segments then reassembles the received data; Also manages the order of the data |
|
|
Term
| Term: Data traveling on the Transport layer |
|
Definition
|
|
Term
| What are the two primary protocols of the Transport layer? |
|
Definition
-Transmission Control Protocol (TCP)
-User Datagram Protocol (UDP) |
|
|
Term
| How does the Transmission Control Protocol (TCP) work? |
|
Definition
| Establishes a session that will not transmit data until a session is established (Connection-oriented) |
|
|
Term
| How does the User Datagram Protocol (UDP) work? |
|
Definition
| Data is sent without first verifying a connection with some data loss; accepts some data loss (Connectionless) |
|
|
Term
| What is the purpose of the network layer? |
|
Definition
| To determine the best route to the destination |
|
|
Term
| Term: Data travelling on the Network layer |
|
Definition
|
|
Term
| What resolves IP addresses to the physical or Media Access Control address? |
|
Definition
| Address Resolution Protocol (ARP) |
|
|
Term
| Term: Data travelling on the data link layer |
|
Definition
|
|
Term
| Term: Data units in layers 5, 6, and 7 |
|

2. Internet layer
1. Link layer |
|
|
Term
| What is the function of the TCP/IP model's application layer? |
|
Definition
| To access network resources and display them for the end user |
|
|
Term
| What is the function of the TCP/IP model's transfer layer? |
|
Definition
| Manages sessions and data transfer |
|
|
Term
| What is the function of the TCP/IP model's internet layer? |
|
Definition
| Control movement and routing of packets between networks |
|
|
Term
| What is the function of the TCP/IP model's link layer? |
|
Definition
| Defines how data is transmitted over media |
|
