LO3 - Network Protocols: Flashcards
What are the four layers of the TCP / IP Stack?
1) Application,
2) Transport,
3) Internet,
4) Network Interface.
What is the Application layer?
The application layer provides the user with the services needed to create messages that can be sent across the internet using a variety of protocols.
What is the Transport layer?
The transport layer breaks the message up into data packets and labels them to be sent to other computers across the internet.
What is the Internet layer?
The internet layer delivers the messages / data packets based on an address that is attached to each packet.
What is the Network Interface layer?
The network interface layer provides the physical connection so that packets of data can be transferred from the network to another interface.
What protocols could be used in the Application layer?
1) HTTP,
2) FTP,
3) POP,
4) IMAP,
5) SMTP,
6) SNMP.
What protocols are used in the Transport layer?
1) TCP,
2) UDP.
What protocols are used in the Internet layer?
1) IP,
2) ICMP.
What protocols are used in the Network Interface layer?
1) MAC,
2) Ethernet.
