In the digital world we live in today, networks are everywhere. Every time we use a computer to browse the internet, play a game with friends online, or watch videos, we are using a computer network. But who makes sure these networks are working smoothly and are protected from problems? That is the job of a network administrator.

In this lesson, we will study the important role of an "Advanced Networking Administrator," what they do, why their job matters, and how it connects with our everyday technology use.

What Is a Network?

A network is a system of connected computers and devices that communicate with one another to share resources such as files, printers, internet access, and more. Networks can be small (such as the ones in a home or classroom) or very large (such as those used in universities, banks, or hospitals).

When you send an email or search on the web, your device connects to other computers and servers through a network. Networks need to be protected, maintained, and organized. This is where the advanced networking administrator comes in.

Understanding the Role of a Network Administrator

A network administrator is responsible for keeping the network running smoothly. Their duties include:

1. Installing Security Programs: This includes firewalls and antivirus systems to stop unauthorized users and harmful viruses.
2. Monitoring Performance: They check the speed and reliability of network connections.
3. Updating Software and Systems: Ensuring everything runs on the latest, safest version.
4. Setting Email and Internet Filters: To block unwanted content or threats.
5. Testing the Network for Weaknesses: Identifying vulnerabilities that hackers could exploit.

A common misunderstanding is that a network administrator also designs the network. While they may give input, network design is usually done by a network engineer or architect. Network administrators focus more on operating and maintaining the network.

What Influences the Work of a Network Administrator?

Several factors affect how a network administrator performs their job:

Interestingly, resources such as available tools or hardware are not a major influence on defining the administrator's role; their responsibilities remain the same regardless.

Tools Used in Network Administration

One of the main systems used by network administrators is an issue tracking system. This is where users report problems with computers or the network, and the administrator responds by solving the issue.

Other tools include:

• Switches and Routers: Hardware that connects and directs network traffic.
• VPN Gateways: These allow secure access to networks from remote locations.
• Firewalls: Software or hardware that blocks unauthorized access.

These tools are important for network security, performance, and remote accessibility.

Roles by Organization Size

The specific tasks of a network administrator can change based on whether they work in a small or large organization.

In small settings, administrators may do a variety of tasks. In larger companies, roles are more specialized.

An example of a task not usually performed by network administrators in large organizations is the correction of software bugs, which is the responsibility of software engineers.

Training and Certifications

To become a network administrator, individuals usually study computer networks and gain practical experience. There are also certifications that help them qualify for advanced roles:

• CWNA (Certified Wireless Network Administrator): Focuses on wireless networking.
• Cisco: Offers a range of certifications for those using Cisco equipment.
• Red Hat: For those managing Linux-based systems.
• Google: Offers certifications focused on cloud technology.

It is important to understand that not all certifications are equally relevant in every job. For example, CCNA is sometimes not suitable in environments where non-Cisco equipment is used.

Cloud Storage Responsibilities

Cloud storage allows data to be saved on internet-based systems instead of physical hard drives. Network administrators play a key role in maintaining cloud systems by:

• Performing software updates
• Ensuring user access is secure
• Monitoring for any potential data breaches or errors

They do not design the storage system itself, but they are essential in ensuring it functions correctly and securely.

Which Industries Need Network Administrators?

Many modern sectors depend on complex networks to operate. Here are some examples:

While technology use is expanding everywhere, some industries may rely less on full-time network administrators.

Important Skills for a Network Administrator

To be successful, a network administrator must have specific skills:

While team management is useful in leadership roles, it is less important for the daily tasks of most administrators.

Common Misunderstandings

• Not all technical problems are for the network administrator to fix. Software bugs are usually fixed by software developers.
• Network design is a separate specialization. Administrators maintain networks rather than create them.
• Certifications vary in usefulness depending on the job type. It is important to choose training that matches the systems used by the organization.
