IP address:An IP address is the unique number assigned to every network device in an Internet Protocol (IP) network; each IP address identifies the device’s host network and its location on the network. When one device sends data to another, the data includes a “header” that includes th...
A hub is a small, rectangular, inexpensive device that joins multiple network-enabled devices. They're often made of plastic and receive power from an ordinary wall outlet. The purpose of a hub is to form a single network segment on which all devices can communicate directly with each other....
When looking at the physical layer of a computer network, there are two primary types: Wired networkingrequires the use of a physical medium for transport between nodes. Copper-based Ethernet cabling, popular due to its low cost and durability, is commonly used for digital communications in busin...
Nodes connect over a link or communication channel. In a computer network these may be cable, fiber optic or wireless connections. What are the types of network nodes? There are several ways to categorize nodes. One way is by network type; another is by network topology. ...
What is a computer network? The term gets a lot of traction, but how do we define it? This article is your one-stop source of information relating to computer networks. Click here to know more.
In this article, we will talk about the much-asked query of what is layer 2 network is and how its works in a typical network. We will also briefly touch on the basic concepts regarding this topic. The data link layer of the OSI model is sometimes called the MAC layer. It's ...
With non-stop cyber threats, you must ensure your networks are strong. Strong enough to combat risks and threats to their security. So, let’s dive deep into the world of network security. In this article, you’ll learn: The actual meaning of network security in computer networks ...
While switches and routers differ in several ways, one key difference is how they identify end devices. A Layer 2 switch uniquely identifies a device by its "burned-in" MAC address. A Layer 3 router uniquely identifies a device's network connection with a network-assigned IP address. ...
