Modern day networking is a very different beast in terms of complexity, though the general idea remains the same: Maintain a digital network of computers, both in server form and even in virtual machine form, and perform all administrative tasks needed in order to do so efficiently and effectively. To do this, software to monitor network traffic and uptime, analyze system logs, and web usage statistics is crucial. That’s where the software in this category comes in to play.
