A device which connects 2 networks - receives data packets from one network and forwards them to another.

Define NIC
Network Identification Card converts signals from a PCs buses into electrical signals. Includes a MAC address.

What is TCP/IP and what's it for? 3 Key points.
It's a SET OF PROTOCALS [Which are RULES] that governo the way computers communicate within networks. It formats communications. Represented by a STACK.

What are the 4 TCP/IP Stack layers
Application - Transport - Internet - Link Layers.
4 of 9
What happens in the Application Layer + state the Protocals found
SMTP, POP3, HTTP. Rules in this layer define the overall format of a network - depending on your application, a protocal is selected appropriates. Basically, defines data formats.
5 of 9
What happens in the Transport Layer + state the Protocals found
TCP (Transport Control Protocal). Packages DAta into PACKETS choosing a format appropriate to each TOP-LEVEL protocal (HTTP, SMTP, etc.); carries out error checks throughout communication.

Discuss the process of TCP - think Handshaking.
A 'GET' packet is usually first thing sent in a web communication, whereby it attempts to get a response - a STATUS CODE will be returned giving the response. This process is called Handshaking.
7 of 9
What happens in the Internet Layer + state the Protocals found
IP. Deals with ADDRESSING inside and outside the network. Computer Addressing uses concept of IP addresses. The IP address of sender and recipeint is added.
8 of 9
What happens in the Link Layer + state the Protocals found
Ethernet, Token Ring. Provides rules defining how the actual Physical Parts of the network works. Adds a MAC Address, uniquely identifes specific computers: sender and recipient's.
