TCP/IP Framework Flashcards
STATELESS INSPECTION
Stateless Protocols are the type of network protocols in which Client send request to the server and server response back according to current state.
It does not require the server to retain session information or a status about each communicating partner for multiple request.
STATEFUL INSPECTION
In Stateful Protocol If client send a request to the server then it expects some kind of response, if it does not get any response then it resend the request.
FTP (File Transfer Protocol), Telnet are the example of Stateful Protocol.

MAC Address
Media Access Control
Example: 00:90:69:9f:ea:46
First the bytes 00:90:69 Organizationally Unique Identifier (the OUI)
Last three bytes 9f:ea:46 Identifies the Unique Network Interface Card (NIC)
Hence, OUI ; NIC are the parts of the MAC address.
48-bit address divided into six octets.
ARP
Adress Resolution Protocol
Full-Duplex Communication
Computers can send and receive data at the same time
Half-Duplex Communication
Computers on older networks were not able to receive and send data at the same time, but switched between the two modes. Not used anymore.
NIC
Network Interface Card (the actual device with a processor that can connect and communicate with the network. The Ethernet port is a part of the NIC where the physical connection to the cable is made.)
OUI
Organizationally Unique Identifier (Identifies the manufactorer)
UNICAST: L2/L3 NETWORK.
SENDS 1 TO 1 COMMUNICATION (SENDS TO ONE COMPUTER ON THE NETWORK)
