Similar to how a phone’s contacts list matches names to numbers, the domain name system is a naming database that locates and translates internet domain names to their unique IP addresses. DNS is used in various internet activities to swiftly discover an IP address to connect to and access content. DNS is important because, for humans, it’s ...
BGP is an external gateway protocol that exchanges routing information between routers in various autonomous systems. It is the protocol that is used between Internet service providers and can also be used between an enterprise and an ISP. The entire route to each destination is included in the BGP routing information. Using the routing information, ...
A public IP address is a unique IP address assigned to your network router by your internet service provider and can be accessed directly over the internet. A private IP address is a unique address that your network router assigns to your device. It is used within a private network to connect securely to other ...
Virtual points where network connections begin and stop are called ports. Ports are software-based and controlled by operating system. Each port is connected to a different procedure or service. Ports allow computers to easily differentiate between different kinds of traffic: emails go to a different port number than webpages, for example, even though both reach ...
The Internet Protocol (IP) is a collection of protocols used on the Internet for addressing and routing data. Every device has an IP address, which uniquely identifies it and allows it to communicate and share data with other internet-connected devices. TCP and UDP are the most widely used internet protocols. TCP stands for Transmission Control Protocol, and UDP is for User Datagram Protocol. TCP is a connection-oriented protocol whereas, ...
Routing is the process of choosing a path for transferring data from a source to a destination. Routing is performed using devices called routers. In order to send the packet by determining the best route from one network to another, routing is carried out at the network layer. The network layer primarily makes sure that ...
A bridge is a computer networking device that connects multiple LANs (Local area networks) together to create a single, larger LAN. The process of aggregating networks is referred to as network bridging. Bridges operate at the data link layer according to the OSI model. A repeater is also a computer networking device operating at the OSI model’s physical layer ...
The OSI model stands for Open Systems Interconnection model. The OSI model is also known as the ISO-OSI model as it was developed by ISO (International Organization for Standardization). It is a conceptual reference model that describes the entire flow of information from one computer to the other computer. The OSI model is a 7-layered model, so it ...
What is File Transfer Protocol (FTP)? How Does File Transfer Protocol (FTP) Work? FTP can be accessed via a basic command-line interface (from a console or terminal window in Microsoft Windows, Apple macOS, or Linux) or with a dedicated graphical user interface. FTP clients can also be used with web browsers. What is the Purpose of ...
Today, the world is connected to the Internet and billions of data are being shared through a wireless network. All of these are done using TCP/IP protocol which uses a three-way handshake and flow control to initiate, terminate the connection, and send and receive data packets. Flow control is an important concept in Computer Networks as it provides reliable ...
