|
Application Layer |
Is the highest layer and provides Network Services to the end users, according to the applications they're using. It's the only layer that users interact with directly |
Layer 7 |
|
|
Presentation Layer |
Protocols at this layer ensure that data represented by one system can be interpreted by another system |
Layer 6 adds data compression and security services like encryption |
|
|
Session Layer |
It establishes connections between device and applications, maintains the connection and terminates or reestablishes it when its required. |
Layer 5 it specifies the procedures for synchronizing data transfer between two devices with different data transmission rates |
|
|
Transport Layer |
End to end data transmission. this layer also implements mechanisms for ensuring reliable data transfer and data integrity, and for correcting transmission error |
Layer 4 Manages connections with the two layers adjacent to it Session and Network Protocols used UDP,TCP |
|
|
Network Layer |
specifies how to route data from host on one network to host on another network, based on the hosts network addresses. This Layer contains several protocol families |
Protocols at this layer: IP, IGMP, ICMP, ARP, RIP |
|
|
Data Link Layer |
Handles Hardware addressing so that physically connected devices can be located. its responsible for transferring data packets between adjacent network nodes w/out any errors. |
Network switches operate at the this layer. Protocols at this layer: PPP, SLIP, SONET and Frame Relay |
|
|
Physical Layer |
is the lowest layer it defines the physical media and specifications a network uses when transferring data |
Layer 1 AP, NICs operate at this Layer Protocols: Ethernet, Fast Ethernet,ATM-Token Ring, FDDI |
|
|
IMAP 4 |
Internet Messaging Access Protocol, is a Application layer internet protocol that allows an email client to access email on a remote mail server. IMAP on SSL is IMAPS on port 993 |
Port 143 |
|
|
Hypertext Transfer Protocol |
is an application layer protocol designed within the framework of the IP suite. Its definition presumes an underlying and reliable transport layer and TCP is commonly used |
Port 80 Port 443 with SSL |
|
|
SMB |
Server message Block operates at the application layer network protocol mainly used for providing shared access to files printers serial ports and miscellaneous communications between nodes on a network |
