Internet Protocol Flashcards
What does TCP/IP stand for?
Transmission Control Protocol/Internet Protocol
What does UDP stand for?
User Datagram Protocol
What are the four layers in the Network Model?
Application, Transport, Internet, and Network Interface
What does the Network Interface layer do?
Responsible for placing TCP/IP packets on the network medium and receiving TCP/IP packets off the network medium. In this way,TCP/IP can be used to connect differing network types.
What does the Internet Layer do?
Responsible for addressing, packaging, and routing
functions. The core protocols of the Internet layer are IP, and ARP:[address resolution protocol (arp), which is a protocol used by the Internet Layer, specifically IPv4, to map IP network addresses to the hardware address
What does the Transport Layer do?
Responsible for providing the Application layer with session and datagram communication services.The core protocols of the Transport layer are Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP)
What does the Application Layer do?
Provides applications the ability to access the services of the other layers and defines the protocols that applications use to exchange data. There are many Application layer protocols and new protocols are always being developed.
What type of link is between User’s Software?
Virtual Link
What type of link is between hardware?
Physical Link
What type of link is between Protocol Software?
Virtual Link
How many bits in IPv4?
32 bits
What is TTL?
Time To Live
Why is TTL important?
To avoid loops in the Network
What’s the difference between UDP & TCP?
TCP is more reliable, ordered, and error-checked.
UDP is less secure but faster.
