If you’re interested in computer networking, you may be wondering which software is commonly used in this field. In this article, we’ll explore some of the most popular software programs used by network engineers and administrators.
Network Operating Systems (NOS)
A Network Operating System (NOS) is a software program that enables multiple computers to communicate with each other and share resources. Some of the most popular NOS options include:
- Windows Server: Windows Server is a server operating system developed by Microsoft. It provides a range of features such as file and printer sharing, remote access, and user management.
- Linux: Linux is an open-source operating system that can be used as a server or desktop OS.
It offers many networking tools such as firewalls, routers, and web servers.
- macOS Server: macOS Server is a server operating system designed for Apple’s Macintosh computers. It includes features such as file sharing, remote access, and profile management.
Network Monitoring Tools
Network monitoring tools are essential for network administrators to keep track of the health and performance of their networks. Some popular network monitoring tools include:
- Nagios: Nagios is an open-source tool that allows users to monitor network services such as SMTP, POP3, HTTP, NNTP, ICMP, SNMP and SSH.
- Zabbix: Zabbix is another open-source tool that can monitor various aspects of network infrastructure including servers, applications, databases, and devices.
- PRTG Network Monitor: PRTG Network Monitor is a commercial tool that provides real-time monitoring for networks of all sizes. It can monitor devices, traffic, and applications.
Network Security Software
Network security is a critical aspect of any organization’s IT infrastructure. There are many software programs available to help secure networks, including:
- Firewalls: Firewalls are hardware or software-based security systems that control network traffic. They can prevent unauthorized access to a network by blocking certain ports or protocols.
- Antivirus software: Antivirus software helps protect computers and networks from malware such as viruses, spyware, and adware.
- Intrusion Detection Systems (IDS): IDS tools monitor networks for suspicious activity and alert administrators if they detect any potential threats.
In conclusion, there are many different software programs used in computer networking. Network Operating Systems (NOS), network monitoring tools, and network security software are just a few examples. By understanding the various options available, you can make informed decisions about which programs will best meet your organization’s needs.
