Transmission mode, also known as a communication mode, is the transfer of data between two devices via a communication channel that includes an optical fiber, wireless channels, copper wires, and other storage media . Data is transmitted between two devices in the form of electromagnetic waves. There are numerous data transmission methods in which the message is delivered in the form ...
Network devices are physical devices that enable communication and interaction between hardware on a computer network. Each networking device operates in a distinct computer network segment and performs distinct functions. A network may require hundreds or thousands of different network devices to maintain and build out various LAN and WAN. Network devices like the hub, bridge, repeater, modem, router, gateway, etc., are the basic building blocks of an extensive network. What ...
IP stands for Internet Protocol, and it is a network address that is assigned to each and every device that is connected to the particular network. A device uses the IP address to communicate with the other devices present on the network. The two of the most commonly used IP addresses are namely IPv4 (Internet Protocol version 4) and IPv6 (Internet ...
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 ...
The network layer and transport layer are two of the seven layers of the OSI model. The network layer is the third layer of the OSI model which provides communication between hosts of different networks. The transport layer is the fourth layer of the OSI model which is responsible for the process to process delivery of ...
