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 engineering 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.
change
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.
Server
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.
Client
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.
Step 3: Prepare For Certification And Networking Training
The third step in getting into
networking is to prepare by taking a certified beginner or intermediate course.
The three certifications required by network professionals are:
