Although the job titles network engineer and network administrator are sometimes used as synonyms, a network engineer usually has more executive responsibilities than a network administrator. The engineering side deals more with planning, design and technical specifications. The administration side deals mostly with day-to-day maintenance, management and troubleshooting efforts.

The job titles may also be differentiated by education or earnings. Typically, a network engineer has more education and earns more than a network administrator. Employment projections show that network engineers are in demand, and the profession — and closely related professions — are expected to grow between 4% to 7% in the next decade.

What does a network engineer do?

Network engineers focus on delivering high-availability network infrastructure to sustain the users’ online and on-site information technology activities. Network engineers often overlap with other roles, such as computer network architects or security systems engineers, and work internally within an organization or as outside consultants.

Network engineers design and implement network configurations, troubleshoot performance issues, carry out network monitoring and configure security systems such as firewalls. They often report to a CIOchief information security officer and other line-of-business leaders to discuss and decide upon overall business goals, policies and network status updates. In many situations, network engineers work closely with project managers and other engineers, manage capacity and carry out remote or on-site support.

network engineer roles and responsibilities
Network engineer roles can include several disciplines.

network engineer skills

A job candidate may only need an associate degree to obtain an entry-level network engineering job, but most positions require a bachelor’s degree in computer science or multiple years of additional experience. Many network engineers also come from fields such as electrical engineering, physics or mathematics.

Engineers must be able to understand complex networks and pinpoint problems or suggest ways to improve them. They must also be able to work collaboratively, as well as instruct other engineers and support staff to operate the network. And they have to be able to be flexible enough to work with both engineers and line-of-business colleagues who may not have any understanding of networking.

In addition to technical skills, network engineers need analytical, leadership, organizational and communication skills. An attention to detail and the ability to problem-solve are also important.

Increasingly, network engineers also need to know about applications and software development, reflecting the growing role of automation and software-defined networking. Therefore, engineers need to understand traffic flows, application priority and data transport.

Additionally, engineers should also become acquainted with hyper-convergencevirtualization, security, containers, wide area networking and storage engineering. They should also understand the basic elements of networks, such as clients, servers, internet routing, IP addresses and network hubs.

how to become a computer network specialist

Finding your next job can be tough. In our technology-driven world, applying for jobs online while in your PJs is a convenience that’s hard to resist. But a crucial component of a successful job search involves networking: getting out there to expand your professional contacts and discover opportunities.

How to network effectively

Networking skills come easily to some, but this is rare. For most of us, they’re an acquired talent and require practice over time. And that practice is well worth the effort: the research consistently shows that internal referrals are the top source of hires, meaning those personal relationships can have significant payoffs.

5 Tips for Becoming a Networking Expert | by Offpich | Medium

1. Start by determining your goals.

Ask yourself what you are looking for from the relationships you hope to develop. Are you anticipating making contacts with a specific future employer? Meeting a new mentor who can provide career guidance or industry expertise? Meeting new people in your industry? Perhaps all of these? Intentionally identifying your networking goals will help you structure questions you want to ask, prepare your elevator pitch and determine requests you have for your contacts.

2. Talk to your friends.

Friends can play a valuable role in your networking efforts. Whether you’re an introvert, new to networking, or having trouble focusing your goals, begin with people you already know. Take them to coffee or lunch and learn the story of their career paths and choices. Focusing your conversation on their professional experiences will reveal new perspectives and ideas, even if you’ve known each a long time. Ask if they can connect you to someone in your field or at one of your dream companies, and build from there.

3. Attend events to meet new people.

Step away from the computer screen and shake some hands. Online networking is a powerful tool, but there’s nothing like face-to-face interaction. If employment is your goal, the networking events you’ll find the most productive are ones that include a diverse mix of job seekers, industry reps, recruiters, and companies seeking talent. If you’re looking to meet peers in your industry or learn more about a new field, you can easily find industry- or career-focused groups and meetups in your local area by searching social media channels.

You can use these networking events to make new connections and then, you’ll be able to follow up and cultivate those relationships with meaningful one-on-one conversations.

Pro tip: Think quality over quantity. Networking is not about trying to meet as many people as you can. It’s not a numbers game. Seek people who will make a difference in your life—and those you can inspire as well.

4. Ask to understand.

Amidst the stress of the job search, it’s easy to become so focused on yourself that you forget to really pay attention to others. When you network, whether at an event or a one-on-one coffee, ask people genuine questions based on your goals and listen closely to their answers.

Clear your mind and focus on listening empathetically and with curiosity rather than with self-interest. You’ll learn a lot in the process and make an impression with your attentiveness. Active listening is a skill we should all practice, and networking events are the ideal opportunity.

5. Build a network matrix.

Target the companies you’re interested in, and seek out people who work for each company or who know someone there. Build a “Who + Where” matrix that matches who you know with where they work and use their name as referrals when you apply for positions at those companies (be sure to ask their permission first). A contact who can provide insight into the hiring manager’s personality or preferences is a real asset. At some companies, employees receive a bonus if their referral is hired; if your friend is lucky enough to work for a company that rewards referrals, you’ll both have something to celebrate.

Below is just one of the ways to organize your network matrix. This example highlights an individual focusing on jobs in the technology industry because they include more contacts from companies in this area. As this example shows, you also can organize your network contacts by relationship and how well you know each individual (in this case, by tier) to understand and prioritize how your contacts can help.

6. Volunteer in your community.

If you can, donate your time to a good cause and mingle with people who aren’t in your industry. It feels good to give your time to others in need, and if you’re unemployed, it’s wise to get out of the house and not spend too much time in isolation. Pick a cause or group that resonates with your values and donate a few hours each month.

Volunteering can help you grow your social network by exposing you to people who share your passions and personal values. You can also volunteer for a professional association to grow career-related contacts as well. Along the way, you may meet mentors and new friends with fresh job leads.

7. Follow up and don’t forget the basics.

After an event, send follow-up emails to your contacts, thank everyone you spoke with, and complete any promised tasks. Even if you haven’t made commitments, stay active and develop your new relationships. And don’t forget to always carry a printed version of your resume and business cards, if you have them. If you’re inviting people in your network out to coffee or lunch, always offer to pay for the meal and send a thank-you note following the conversation.

how to practice computer networking skills

Computer networking is at the foundation of every business. It’s what connects devices and allows an organization to communicate internally and with the outside world. If you’re looking to jumpstart your career in this sought-after field, learning the networking basics is a great place to start.

In this blog post, we’ll discuss how to break into networking in three easy steps. 

Step 1: Learn the Components of a Network

The first step toward becoming a networking professional is learning the components of a network and how they work together.

There are several essential components in a network:

  1. Switches
  2. Access Points
  3. Servers
  4. Clients
  5. IP Addresses
  6. Routers and Firewalls

How Network Components Work Together

Switches and access points connect the devices or “clients” in a network so they can talk to each other.

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

Servers host and send information in the form of web content, applications and files to client devices. They use IP addresses for direction.

Routers control the flow of information from servers to clients and outside networks. Firewalls protect a network from unwanted users and messages.

Here’s how each network component works:


Switches are pieces of hardware that connect devices in a network. They allow information to be sent between PCs, printers, mobile devices, servers and other devices quickly and efficiently. You connect devices to a switch with cables.

There are two types of switches: managed and unmanaged.

  • Unmanaged switches are typically used for home networks. To create a network with an unmanaged switch, you just plug devices into it.
  • Managed switches are used for bigger networks. You can configure them to provide greater network security and prioritize local area network (LAN) traffic.

Whether you use a managed or unmanaged switch, the purpose is the same: to enable cross-device communication by creating a shared pool of resources.

Access Points

An access point is a hardware device that allows Wi-Fi enabled devices to connect to a network without cables. It can be built into a router or connected via ethernet cable. Access points are customarily used for networks with many devices like an office, school or coffee shop.

Also known as “hotspots,” access points allow people to connect any device to a network if they’re within a defined geographic radius.


A server is a high-powered machine that dispatches data to devices in a network. There are several types of servers including web, email, FTP and identity.

  • Web servers send data to client devices through browsers like Chrome, Firefox or Safari. They deliver web pages and files stored in the cloud to phones, PCs and other devices.
  • Email servers allow email programs like Gmail or Outlook to send and receive messages.
  • FTP (File Transfer Protocol) servers let you remotely copy and move files from one device in your network to another.
  • Identity servers are databases that store the user credentials for a network. Identity servers allow IT departments to authenticate user access.


Clients include any computer hardware or application in a network that requests data from a server. This client-server relationship is what makes a network function.

The most common types of network clients used by businesses are desktops, laptops, tablets, phones, lights and AI devices.

IP Addresses

IP addresses are unique identification codes for network devices that tell servers where to send data. A device must have an IP address to allow other devices to establish a connection with it.

IP addresses can be public or private.

  • Public IP addresses identify your network to external devices and networks.
  • Private IP addresses also identify network devices, but they are only visible to your network.

Most internet service providers assign a public IP address to your network router and private IP addresses to user devices. If a machine outside your network wants to relay data to a user device within your network, it will use your router’s public IP address to transfer the information. From there, your router will send the data to the user device using a private IP address.

Routers and Firewalls

A router acts as the gateway to your network. It also allows all networked computers to use one internet connection.

Routers analyze data coming into your network and tell it where to go.

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

A firewall is the most basic level of network security. It scans incoming and outgoing network traffic and decides whether to allow or block it. You can configure a firewall to allow or disallow various types of traffic.

Step 2: Choose a Networking Job Role

The second step to launching your networking career is to choose a job role. There are many jobs in the networking field to choose from, including:

  • Network specialist
  • Network technician
  • Network administrator
  • Network analyst
  • Network manager
  • Network engineer
  • Network solutions architect

Network Specialist

Network specialists install and configure network components. They set up, support and maintain local area networks (LANs), wide area networks (WANs) and other networking systems.

Becoming a networking specialist is a great way to break into IT. Most employers typically require 2-3 years of IT experience or an entry-level networking certification like the Cisco Certified Entry Networking (CCENT). Network specialist is a hands-on position with room to grow.

Network Technician

Network technicians have a wide variety of responsibilities.

They troubleshoot software and hardware issues within a network, make repairs, perform scheduled updates and provide technical support to clients. Network technicians typically inspect cable line connections to make sure they’re working. They also work with an IT team to outfit devices with security software.

An IT team usually relies on its network technicians to manage hardware and software installation and upgrades.

To become a network technician, you typically need:

  • Five years of experience in an IT support role
  • A bachelor’s degree in computer engineering or a related field
  • A strong background in server management, software installation and upgrades
  • A basic understanding of computer network cabling
  • Customer service experience

Network Administrator

Network administrators oversee an organization’s IT infrastructure and ensure it’s up to date. A network admin’s primary responsibility is making sure all of the software and hardware platforms within an organization are connected and communicating with each other to drive the business forward.

Network administrators need to be well-versed in a variety of networking specialties including design, configuration, troubleshooting, upgrades, software deployment, server management, storage and security.

To become a network administrator, you should understand popular networking products and systems like CiscoCitrix and Microsoft Active Directory. Network administration can be an entry-level role if you have the right amount of training and experience. You can earn a degree in network administration online or supplement a computer science or software engineering degree with field experience.

Network Analyst

Network analysts are responsible for identifying business issues within an organization and solving them with information technology. They plan, design, analyze and provide technical support for their client’s network. It is a senior networking role that typically requires a bachelor’s degree and 1-5 years of experience serving clients and working on teams.

Network analysts must draw upon their business and technical insight daily to present IT solutions that increase efficiency and profitability for an organization.

Network Manager

Network managers have two primary roles:

  1. Installing, configuring and troubleshooting client computer networks
  2. Training IT staff to provide excellent tech support and customer service

When a technology problem comes up for a client, the network manager is responsible for getting it resolved — whether that means deploying a team of engineers, connecting clients with technicians or escalating the problem to an analyst.

Above all else, network managers keep tabs on problems that arise and put systems and technology in place to prevent them from recurring.

To become a network manager, you need:

  • A bachelor’s degree in computer systems or equivalent experience
  • Relevant certifications, such as the Cisco Certified Network Professional (CCNP) and CompTIA Network+
  • Experience with basic network components

Network Engineer

Network engineers perform many of the same tasks as a network admin, but on a more technical and strategic level. They design and configure network and security systems to support the chief information officer’s overall IT goals for an organization.

Unlike other network execution roles, network engineers are involved in giving network status updates to IT decision makers to influence business decisions.

With a relevant bachelor’s degree and the right certifications from Cisco, Microsoft and CompTIA, you can break into networking as an engineer. Engineers with several years of line-of-business experience can earn more than $115,000 annually.

Network Solutions Architect

A network architect is a senior position in information technology and a step up from a network engineer. They are responsible for an organization’s long-term network strategy.

Network architects analyze computer network problems affecting business operations and devise 3-5 year roadmaps to improve performance. In addition to designing network solutions, network architects must be able to plan, budget, model and track performance.

To become a network solutions architect, you need 5-10 years of industry experience and a wide variety of certifications, which may include several of the following:

  • Cisco Certified Design Associate (CCDA)
  • Cisco Certified Design Professional (CCDP)
  • Cisco Certified Design Expert (CCDE)
  • Cisco Certified Architect (CCAr)

how to become expert in networking

 be great if we could get a job from the safety of our couches, in our pajamas, without having to leave the house. Unfortunately, almost no one actually gets hired from online applications. Networking is still the best way to get your foot in the door. And networking requires both wearing pants—and social skills. Here are five things you absolutely have to do to be one step closer to becoming a networking expert.

Prepare in advance

Have a plan before you walk up to the big fish and try to reel them in. Figure out whom you might have the opportunity to meet at any particular event, then learn as much as you can about them. Figure out what you should emphasize to each, and how best to frame yourself. Practice your pitch. Bring plenty of business cards.

Ease Up

This isn’t the same as selling used cars. You’re not the Avon lady. Most sentient humans will appreciate a little more sincerity. Remember—you don’t have to be in sales mode all the time in every encounter. Try connecting on a personal level first and letting the conversation evolve naturally before you start thrusting your business cards in people’s faces.

Show up

As great as it would be to send somebody to network for us, this just doesn’t work. Don’t send a friend or colleague—or your sister—to shake hands with that particular hiring manager if you can’t attend yourself. Send a professionally worded email explaining how much you’d like to meet and see if you can’t find another opportunity instead.

Expand your reach

Don’t play it safe. Your contacts, no matter how many you have, are not enough. It will always be beneficial to keep growing your network and making more connections. You never know when you will need them. Get out there and mingle!

Follow up

This is perhaps the most important step in the whole process. Whether you send a handwritten note or an email, it’s absolutely crucial to follow up. It shows your interest and your professionalism, and has the added benefit of reminding that connection you exist!
