Computer networks are the foundation of any business. Connects devices and enables organizations to communicate with the internal and external worlds. If you want to start your career in this popular area, start by learning the basics of networking.


In this blog post, I will show you how to get into your network in three easy steps.


Step 1: Learn The Network Components


The first step in becoming a network engineer is learning the components of the network and how they work together.


The network has some essential components.

  • ·         change
  • ·         access point
  • ·         server
  • ·         client
  • ·         IP adress
  • ·         Router and firewall


How To Link Network Components


Switches and access points connect devices or "clients" on your network so that they can communicate with each other.


Each client has a numeric label called an IP address. This address identifies the location of the client device and identifies it as belonging to the network.


Servers host information in the form of web content, applications, and files and send it to client devices. Use the IP address for the address.


Routers control the flow of information from the server to clients and external networks. Firewalls protect your network from users and spam.


The mechanism of each component of the network is as follows.




A switch is the piece of hardware that connects the devices on your network. Send information quickly and efficiently between PCs, printers, mobile devices, servers, and other devices. Wire the device to the switch.


There are two types of managed switches and unmanaged switches.


Unmanaged switches are commonly used for home networks. To create a network on an unmanaged switch, simply connect your device to it.


Managed switches are used for larger networks. It can be configured to improve network security and prioritize local area network (LAN) traffic.


The purpose is the same whether you use a managed switch or an unmanaged switch. Create a shared resource group to allow communication between devices.


Access Point


An access point is a hardware device that allows Wi-Fi enabled devices to connect to your network without a cable. It can be integrated into the router or connected with an Ethernet cable. Access points are commonly used to network with many devices, such as offices, schools, coffee shops, and more.


Access points, also known as "hot spots", allow any device within a defined geographic area to connect to your network.




A server is a high-performance machine that sends data to devices on your network. There are several types of servers, including web, email, FTP, and ID.


The web server sends the data to the client device through a browser such as Chrome, Firefox, Safari. Deliver web pages and files stored in the cloud to phones, PCs and other devices.


A mail server allows you to send and receive messages with mail programs like Gmail and Outlook.

You can use a file transfer protocol (FTP) server to remotely copy and move files from one device on your network to another.


Identity Server is a database that stores user credentials for your network. Identity Server allows IT to authenticate user access.




Clients include computer hardware or applications on the network that request data from the server. This client-server relationship is what makes the network work.


The most common types of network clients used by businesses are desktop computers, laptops, tablets, phones, lights, and artificial intelligence devices.


IP address


The IP address is a unique identification code for a network device that tells the server where to send the data. To allow other devices to establish a connection to the device, the device needs an IP address.


The IP address can be public or private.


Public IP addresses identify your network to external devices and networks.


Private IP addresses also identify network devices, but are only visible to the network.


Most Internet service providers assign public IP addresses to network routers and private IP addresses to user devices. When non-network machines transmit data to users' devices within the network, they use the router's public IP address to transfer information. From there, the router uses the private IP address to send data to the user's device.


Router and firewall


The router acts as a gateway to your network. Also, make sure that all computers connected to your network have a single Internet connection.


Routers analyze the data entering your network and tell you where to go.


You can customize your router with additional security features to protect your network from network attacks. One type of protection is a firewall.


Firewalls are the most basic level of network security. Analyze incoming and outgoing network traffic.


Step 2: Select A Role For The Network Job


The second step in starting a career online is choosing a job. There are many jobs to choose from in the networking area, including:


  • ·         Network specialist
  • ·         Network Technician
  • ·         Network Administrator
  • ·         Network analyst
  • ·         Network Administrator
  • ·         Network engineer
  • ·         Network Solutions Architect


Network specialist


Network specialists install and configure network components. Set up, back up, and maintain local area networks (LANs), wide area networks (WANs), and other network systems.


Becoming a network specialist is a great way to get into IT. Most employers generally require 2-3 years of IT experience or entry-level network certification, such as Cisco Certified Entry Network (CCENT). Network specialists are in a practical position with room to grow.


Network Technician


Network Technician have several responsibilities.


They troubleshoot software and hardware problems on the network, make repairs, perform regular updates, and provide technical support to customers. Network technicians generally inspect cable line connections to make sure they are working. We also work with our IT team to equip our devices with security software.


IT teams generally rely on network technicians to manage hardware and software installations and updates.


To become a Network Technician, you usually need:


  • ·         5 years of experience in the IT support role
  • ·         Bachelor of Computer Engineering or Related Field
  • ·         Solid experience in server administration, software installation and updates.
  • ·         Basic knowledge of computer network cables.


Network Administrator


Network administrators monitor the organization's IT infrastructure to make sure it is up to date. The primary responsibility of the network administrator is to ensure that all software and hardware platforms within the organization are connected and can communicate with each other and drive business.


Network administrators must be familiar with various network disciplines, including design, configuration, troubleshooting, updates, software deployment, server administration, storage, and security.


To become a network administrator, you must understand common network products and systems such as Cisco, Citrix, and Microsoft Active Directory. With the right amount of training and experience, network administration can be a core role. You can earn a degree in Network Administration online, or supplement your degree in Computer Science or Software Engineering with Field Experience.


Network analyst


Network analysts are responsible for identifying business problems within their organization and solving them with information technology. They provide customer network planning, design, analysis, and technical support. An advanced networking feature that generally requires a bachelor's degree and 1-5 years of customer service and teamwork experience.


Network analysts need daily access to business and technology information to present IT solutions that improve the organization's efficiency and profitability.


Network Administrator


The network administrator has two main roles.

Installation, configuration, troubleshooting of the client computer network

IT staff training to provide superior technical support and customer service.

If a customer encounters a technical problem, it is the responsibility of the network administrator to resolve it. This means deploying a team of engineers, connecting clients with technicians, or escalating problems with analysts.

Best of all, network administrators monitor problems that occur and implement systems and technologies to prevent them from happening again.

To become a network administrator, you need:

  • Bachelor of Computer Systems or equivalent experience
  • Related certifications such as Cisco Certified Network Professional (CCNP) and CompTIA Network +
  • Basic experience of network components


Network Engineer


Network engineers perform many of the same tasks as network administrators, but on a more technical and strategic level. They design and configure networks and security systems to support the overall IT objectives of the organization's chief information officer.


Unlike other network executive roles, network engineers are involved in providing IT decision makers with network status updates to influence business decisions.


With a relevant bachelor's degree and appropriate certifications from Cisco, Microsoft and CompTIA, you can enter the network as an engineer.
