Network management, it includes not only components that transport information in the network, but also systems that generate traffic in the network. iii. The systems could be hosts, database servers, file servers, or mail servers. In the client-server environment, network control is no longer centralized, but distributed. iv. Computer and telecommunication networks are merging fast into converged network with common modes and media of transportation and distribution. As in the case of broadband networks, the IT manager needs to maintain both types of networks. v. Thus, the data communications manager functions and telecommunication manager functions have been merged to that of the IT manager. vi.

When it comes to having a wireless network at your home or business, having wireless security is essential. Having good wireless security can make your wireless network less susceptible to hackers and can make connecting to the network difficult for those who you do not want to have access. Regardless of your wireless router, configuring wireless security on your router merely requires going to the correct section of the administration control panel. Step 1 Type your router's administration control panel address into Internet Explorer. For Linksys/Cisco routers, the address is 192.168.1.1. For D-Link and Netgear routers, the address is either 192.168.0.1 or 192.168.1.1. For other routers the address may be 192.168.1.1, 192.168.0.1 or 192.168.2.1. If none of these work for you, consult your router's user manual. Step 2 Type in your user name and password for the administration control panel of your router, and click "OK." For Linksys/Cisco routers, the default user na...

In the past, wired networks were considered to be far more secure than wireless networks. Today, however, wireless networks are as secure as wired networks, so long as they are properly configured. According to TechTarget, "When comparing wireless vs. wired security, securing a wireless network is even more important than securing a wired network for one simple reason: Accessing a wireless network does not require physical access to a network jack or cable, as does accessing a wired network. Wireless networks use radio transmissions to carry data between end users and the network and it is difficult to contain those radio waves. Therefore, it’s possible for someone to sit in your office building's lobby or parking lot and eavesdrop on wireless network communications." How can MSPs safeguard wireless networks against unauthorized access? There are several tools that MSPs and IT administrators can use to protect the wireless networks they manage, including: Encryption. Enc...

A network operating system is a software application that provides a platform for both the functionality of an individual computer and for multiple computers within an interconnected network. Basically, a network operating system controls other software and computer hardware to run applications, share resources, protect data and establish communication. Individual computers run client operating systems, while network systems create the software infrastructure for wireless, local and wide area networks to function. Basic Operating Features Network operating systems support the basic underlying operating features of networks. These include support for processors and the various protocols that allow computers to share data. Many network operating systems can detect hardware within the system to allow for asset discovery within the network. Also, network operating systems support the processing of other software applications that run on both individual computers and within the network. Se...

The good news is that in many NOCs, rapid advancement may be possible. The first step is to simply observe your organization’s employment structure and what it takes to get promoted. You may find that your NOC follows a seniority-based promotion path. If that’s the case, there may be no other choice but to wait it out. However, most companies offer options for career-minded techs to jump the line. Your goal is to stand out as someone who doesn’t just show up to work. The NOC’s senior technical positions have a deeper involvement in the inner workings of network operations and the company’s IT infrastructure as a whole. The surest way to get consideration for these positions is to take a deeper stand within your own role. If you’re a newcomer, it probably won’t take long before you recognize some weak spots in the NOC’s monitoring and resolution processes. These present opportunities to move up and increase your value. However, avoid the temptation to assume you must work for a bunch o...
