How Does a Computer Network Hub Work?

A network hub is a networking device that connects to one or more equipment. For example, a computer can connect to a server, printer and another computer through a network hub. It is useful in sharing of resources and broadcasting data it receives. It helps connects these devices together without having to connect to each other directly. There are three types of network hubs: Passive Hubs, Active Hubs and Intelligent Hubs.

Passive Hubs
One of the types of a network hub is the so-called passive hub. It's a pass-through that does not do anything more than just broadcast signals it receives through its input port, then sends it out through the output port. It does not do anything to regenerate or process the signals because it only functions as a connector of different wires in a topology.

Active Hubs
An active hub works more than just a connector but also regenerates the data bits to ensure the signals are strong. Another name for an active hub is a multiport repeater. It provides an active participation in the network aside from acting as an interface. It participates in the data communication, such as storing signals received through the input ports, before forwarding them. It can monitor the data it is forwarding and sometimes help improve signals before forwarding them to other connections. Such a feature makes troubleshooting of network problems easier.

Enabling the Computer Browser service for Windows Server

The Advantages of Authentication

There are numerous advantages of authentication systems which are used to identify the user of a home, ATM or a security clearance computer system. The main purpose of these systems is to validate the user's right to access the system and information, and protect against identity theft and fraud. While there are still drawbacks with some systems, as the business world and the electronic marketplace become more complex, the advantages of authentication are ever more obvious. Password Based Authentication The use of a password and username is the most common form of authentication used and is generally considered the cheapest and most convenient method. This requires the user to provide and remember a key containing a specified amount of alpha and numeric characters in relation to a username or e-mail address which must be correct at each login. Passwords saved on a network can be encrypted to prevent theft by employee or programs designed by hackers. Device Based Authenticatio

Server Work Queues of networking

  This is something you should only measure on your Terminal Server(s). You should monitor the "current commands" in the Redirector object. If the value is higher than 20 during sustained periods of time then you could have a bottleneck. Server Work Queues The Server Work Queues object should be monitored on the File server. You should monitor the "Available WorkItems" counter. Sustained values smaller than ten mean that the File server is running out of work items. When it does, performance really starts to plummet. Make sure this doesn't happen by upping the MinFreeworkItems value. Server In this object there's a counter called "Work Item Shortages". This value represents the number of times no work items were available or couldn't be allocated to service a file request. Obviously if you see any other value than zero, you need to start worrying. Upping the InitWorkItems or MaxWorkItems could help out here. Again, there's so much more you
