Internet Protocol (“IP”) Address
The third layer of the TCP/IP (the IP Layer) is the most important to us so we will spend a lot of time on this specific subject. We’ll start with the concept of using an IP address to create a fully functional network over the IP address technology. To make our study of IP easier,…
TCP/IP, a Closer Look
The OSI Model isn’t the only way that network engineers view networks. We can also use a second kind of model called the TCP/IP Model. The TCP/IP Model is another model (Also known as Internet Protocol Suite) that helps us understand the set of rules and guidelines that allows computers to communicate over a TCP/IP…
How Data Travels Between Devices Through the OSI Model
To demonstrate how a packet travels from Machine A’s OSI Model to Machine B’s OSI Mel, we want Machine A to contact the web service HTTP on Machine B. This is equivalent to opening a web browser and typing in the address of the website we’re trying to connect to e.g., http://www.nemyenterprises.com. This address is…
Service Protocols
Service Protocols divide the data into packets when sending or receiving data from another computer in what is known as the packet switching technique. The beauty of this is that all of the installed protocols on the network will be able to connect to each other without any problem because most modern protocols are built…
Network Fundamentals
The OSI Model In its simplest form a network consists of two devices that can send and receive data between them. In this post, we will focus on how a network actually works, starting with how a packet travels between two machines in the same network and to a different machine in another network. Once…
