The devices use a variety of protocols and algorithms to determine precisely how endpoints should send and receive data.
For example, the Ethernet standard sets a common language for wired network communications, and the 802.11 standard does the same for wireless local area networks (WLAN).All packet-switched networks use TCP / IP.
Endpoint nodes include switches and routers, servers, PCs, phones, network printers, and other peripherals, as well as sensors and actuators.The capacity of a network indicates how much traffic the network can support at a given time if service level agreements (SLAs) are met.
A computer network is mainly composed of four types:Types of computer network LAN (local area network) PAN (Personal Area Network) MAN (Metropolitan Area Network) WAN (Wide Computer Network)Job titles in the computer networkIn the computer network, there are different types of professional positions with different salaries and long-term career potential.
Boring, vague or too stormy headlines often do not describe the actual work tasks of a person in this field.The basic job titles displayed for computer networks and network-related items include:Network Administrator: Configures and manages local area networks (LANs) and sometimes even geographic networks (WANs).Network technicians (systems): The focus is on system updates, evaluation of supplier products, safety tests, etc.Network Technician (Assistance): The focus is more on installing, troubleshooting, and repairing specific hardware and software products.
Service technicians often travel to remote customers for on-site updates and assistance.Network Programmer / Analyst: Creates software programs or scripts that are useful for network analysis, such as: Diagnostic programs or monitoring utilities.Network / Information Systems Manager: oversees the work of administrators, engineers, technicians, and programmers with a focus on long-term planning and strategic thinking.Experience with computer networksJobseekers' widespread complaint that "employers hire only experienced people, but the only way to gain experience is recruitment," also applies to computer networks.
