In networking, a node is an access point in a network where data can be processed, stored, or forwarded. It's essentially any device that can send, receive, or forward information. A node could be an end device like your host computer, server, printer, or mobile device. Network devices ...
Networking Fact Checked What is a Loopback Test?By Kurt Inman Updated: May 16, 2024 Views: 16,483 Share A loopback test is a simple method to determine whether communication circuits are functioning at a basic level. It often involves connecting a loopback device to a circuit and verifying...
Switches:Switches are networking devices that facilitate the connection and communication between devices within a network. They direct network traffic by receiving data packets and forwarding them to the appropriate devices. Switches come in various sizes and configurations, including unmanaged switches for...
Another way to categorize nodes is by how they are arranged in a physical computer network. This is known as thenetwork topologyapproach. Some common network topologies include these four: Bustopology connects individual nodes directly to a main cable. Ringtopology has nodes connected in a loop o...
An infiniteloop-- sometimes called anendless loop-- is a piece ofcodethat lacks a functional exit so that it repeats indefinitely. In computer programming, a loop is a sequence ofinstructionsthat is continually repeated until a certain condition is reached. ...
2. What Is a Loopback Interface? In contrast to regular network interfaces, which represent physical hardware devices,a loopback interface is a virtual interface. Therefore, it doesn’t represent any hardware devices and has no physical cables or connectivity to other devices. ...
A microburst occurs when a large amount of burst data is received in milliseconds. Typical microbursts last for 1 to 100 milliseconds, so that the instantaneous burst data rate is tens or hundreds times the average data rate or even exceeds the port bandwidth. The NMS or network performance...

127.0.0.1: This IP address is known as the loopback address, which a computer uses to identify itself regardless of whether it has been assigned an IP address. 169.254.0.1 to 169.254.254.254: A range of addresses that are automatically assigned if a computer is unsuccessful in an attempt to...
a physical form. Instead, the network interface can be implemented in software. For example, the loopback interface (127.0.0.1for IPv4 and::1for IPv6) is not a physical device but a piece of software simulating a network interface. The loopback interface is commonly used in test ...
