Components of a Computer Network


In this essay, I will explain computer networks’ structure, types, and components. I’ll go through the many types of devices used, the people who benefit from the network environment, how a network is technically organized 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 typically wired or wirelessly connected to one another through routers and switches. A router is a tool used to connect devices over a network. In order to link computers in a LAN environment, 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, utilize 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 with certain permissions. This is accomplished using several techniques that the server operating system permits. The server authenticates users before granting them access to the server environment. In this way, the workplace is secure. Users of various levels might be able to use other devices, such as printing documents. Important correspondence should be copied and scanned. 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 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. People who work as network administrators and support staff typically have a strong technical background and a wealth of experience because they are responsible for maintaining the network, which is the primary platform to manage a company’s enterprise. Users and workers are unable to work or carry out daily tasks if a network is offline.


Network troubleshooting uses a lot of technical jargon and procedures. Common network issues include slow networks, issues with wifi signals, and issues with input, output, and storage devices. Failure of the cables, the ram, the hard drive, or the connection On the software side, issues include excessive CPU use on servers and client systems, DNS speed, network outages, natural and unplanned disasters, hardware failures such as servers, printers, routers, cable lines, etc., overheating problems in servers and workstations, slow lookups, strange behaviors brought on by broken devices, DHCP, wifi interference, duplicate IP addresses, static and dynamic IP addresses, firmware corruption, issues with firmware upgrades, and more , router resets, configuration of the router, active directory setup, active directory users, printers, scanners, and more. Other issues include removing useless programs and files; updating drivers, operating systems, and firmware; and taking all other essential actions to make devices quick and effective. People who work in networking also recover and fix data from papers, spreadsheets, and accounting software like QuickBooks. Exchange server issues, issues with the Outlook client, issues with Mac mail, issues with Google, Hotmail, and social media, as well as issues with troubleshooting various servers and server operating systems. Setup, troubleshooting, connection security, encryption, IP address concealment, and LAN or WAN connection for a VPN (Virtual Private Network). Tools like the ping command, ipconfig, tracert, and Netstat are used by administrators and support personnel. Use ipconfig, route, putty, nslookup, and a DNS check to troubleshoot difficulties with your ISP, database logs, viruses, and malware. Setup, configuration, troubleshooting, connectivity, user authentication, Active Directory, connectivity issues for users, and server setup following a crash for both wired and wireless routers Other issues include those brought on by human mistakes, new configurations, and network or power outages.


Installation and troubleshooting of hardware or software are essential for any network system. Installing the Windows operating system, Apple OS X, IOS, MS Office, etc. on client PCs and all devices are examples of software-related jobs. Slow workstation computers, such as PCs, Macs, Windows, and Apple OS X-based clients and servers, as well as new router purchase, installation, and cable installation, are examples of hardware.Installing and configuring switches, and connecting connections to clients, servers, printers, fax machines, and scanners. replacing outdated equipment with newer models, including switches, servers, hard drives, motherboards, logic boards, power supplies, PCs, printers, routers, iMacs, MacBook Pros, and Mac Minis. Raid array setup, raid array troubleshooting, raid array repair, hard drive replacement in raid, setting up external storage, setting up Time Machine for a small network, and data recovery from raid and external storage are examples of other hardware installations. establishing or adding to the network of iPads, iPhones, laptops, desktop workstations, printers, scanners, and portable devices. The repair of all computer components, such as the keyboard, trackpad, video card, sound card, operating system, system files, boot files, modem, network interface card (NIC), network cable, microphone, and webcam, falls under the category of hardware troubleshooting database records.


In this essay, I defined a network and what is contained in a network environment. I also discussed what kinds of problems users can face.
