I will explain computer networks, their structure, types, and components in this essay. I'll go through the many types of devices utilised, the people who benefit from the network environment, how a network is technically organised and maintained, and what goes into network troubleshooting. In a workgroup or server setting, a computer network is an arrangement where all computers, laptops, printers, scanners, tablets, and other devices are connected to one another. A network where every computer and device operates independently while yet being connected to one another is referred to as a workgroup environment.
In this setting, storage and printers can be shared. In this form of network, several users can only simultaneously access files. Small, medium, and corporate network environments are the three main network sizes. In a network, computers are often wired or wirelessly connected to one another by routers and switches. A router is a tool used to connect devices over a network. In order to link computers in a LAN environment, a router includes numerous client ports. There is only one port available for WAN connections, which can be used to link the router to an ISP modem or another router. A router performs numerous tasks.
It can be configured to use static or dynamic IP addresses, act as a firewall, etc. A switch is a device that functions mostly in the same way as a router but has fewer features, such as the inability to give connected devices static IP addresses. Networks come in LAN, PAN, MAN, and WAN varieties.
In an office or corporate setting, the major goal of a network is to enable personnel to access and share resources.
Users connect to the server via client computers in a server-based environment to store and share resources like files, printers, apps, scanners, and data. Emails and other forms of messaging are useful forms of communication in a network context. All users, from the CEO to an employee, utilise the email system, which is stored on an exchange server. All email data pertaining to users and email senders is saved on the Exchange server. Data storage is a network's other significant function. On the server, every user is verified. They have designated folders where they can store their private information. Each user has unique permissions for server data directories. For network users, administrators configure things. So that one user cannot access the data of another user, they provide them certain permissions. This is accomplished using several techniques that the server operating system permits.
Before granting users access to the server environment, the server performs user authentication. In this way, the workplace is secure. The ability to access and use additional devices, such as printing documents, copying, and scanning significant correspondence, may be available to users of all levels. Servers also give consumers access to VPN benefits.
Software and hardware together typically make up a network. Operating systems on client devices, servers, tablets, client and server firmware installed on network devices, printers, scanners, all input or output, and all other drives device drivers are all examples of software. Administrators and support staff are those who handle any problems relating to hardware or software. They are the first point of contact for simple problem-solving.
Technical support specialists with experience are required for advanced assistance, particularly hardware support. Because they must support the network, which serves as the primary platform for conducting business activities, network administrators and support staff typically possess a strong technical background and a wealth of knowledge. Users and workers are unable to work or carry out daily tasks if a network is offline.
