Introduction to tcp/IP

The Network Access Layer

The Network Access Layer monitors the data exchange between the host and the network. Oversees MAC addressing and defines protocols for the physical transmission of data.

The hardware connected to the Network Interface is listed below:

Network medium: This is usually coaxial or twisted pair cabling. In networking today, wireless has become attractive.

Network interface card (NIC): The NIC has the following addresses:

• MAC address, which is a physical address
• IP address, which is a logical address

Fiber Communication Process

A wireless home network is so much more convenient but your sacrificing speed and security. With a wired home network, you generally have a faster speed and even more secure network. You can use this tutorial for your home/office network.
Even though a wired home network provides faster network speeds, that doesn't guarantee faster Internet speeds. Your LAN speed would be at 100 Mbps or 1000 Mbps but your Internet is typical slower than that around 12, 15 and even 24 Mbps. This tutorial on setting up your home network can assist you no matter what speed your network and Internet is running at.
The most popular home network is Ethernet. This type of network is very fast for its low cost. An Ethernet network has speeds of 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet) and 1000 Mbps (Gigabit Ethernet).
Just remember this simple rule, the network device with the lowest data rate speed defines your network speed. This means if your switch can reach up to 1000 Mbps and your computer's Ethernet port is only 100 Mbps, then the switch will transmit at 100 Mbps. You would be wasting a lot of potential and money if you don't remember this rule. The good news is that 100 Mbps is more than enough for your home network because your Internet speed is much lower than 100 Mbps.
Setting up a home network is very fun and will give you a lot of confidence and knowledge if your pursuing a career in computer networking.
