A network is a collection of computers, servers, devices, or other nodes interconnected by communication links for the purpose of sharing resources, exchanging data, and communicating with each other. These communication links can include wired connections (such as Ethernet cables or fiber optics) or wireless connections (such as Wi-Fi or cellular networks).
Netiquette, a portmanteau of “net” (short for internet) and “etiquette,” refers to the code of conduct or guidelines for appropriate behavior and communication while using digital communication tools, such as email, social media, online forums, chat rooms, and messaging platforms. Netiquette aims to promote respectful, courteous, and effective communication in online interactions.
A network topology describes the arrangement of systems on a computer network. It defines how the computers, or nodes, within the network are arranged and connected to each other. Some common network topologies include star, ring, line, bus, and tree configurations. These topologies are defined below:
Stands for “Open Shortest Path First.” OSPF is a method of finding the shortest path from one router to another in a local area network (LAN). As long as a network is IP-based, the OSPF algorithm will calculate the most efficient way for data to be transmitted.
A nybble, sometimes spelled “nibble,” is a set of four bits. Since there are eight bits in a byte, a nybble is half of one byte. While it may take the average person several nibbles to equal one bite of a cookie, in the computer world, two nybbles always equal one byte.
A pebibyte is a unit of data storage that equals 2 to the 50th power, or 1,125,899,906,842,624 bytes.
In networking, a packet is a unit of data that is transmitted over a network. It consists of two main parts: a header and a payload.
Stands for “Simple Network Management Protocol.” SNMP is used for exchanging management information between network devices. For example, SNMP may be used to configure a router or simply check its status. There are four types of SNMP commands used to control and monitor managed devices: 1) read, 2) write, 3) trap, and 4) traversal operations.
A petabyte is 2 to the 50th power, or 1,125,899,906,842,624 bytes.
Each spoken language has a general set of rules for how words and sentences should be structured. These rules are collectively known as the language syntax. In computer programming languages, syntax serves the same purpose, defining how declarations, functions, commands, and other statements should be arranged.
