Hai friends today i am very happy to say u about WIRELESS NETWORKING why i am said that happy means bcoz i love wireless and networking .first u have to learn some basic fundamentals about wireless networking means what is the wireless networking,how wireless network works ,what is frequency bands etc..... so first read some questions and answers for this post we continue later in the next post What Is a Wireless Network?: Five Questions to Start With What is a wireless network? How is it different from a wired network? And what are the business benefits of a wireless network? The following overview answers basic questions such as What is a wireless network?, so you can decide if one is right for your business. What Is a Wireless Network? What is a wireless network, exactly? A wireless local-area network (LAN) uses radio waves to connect devices such as laptops to the Internet and to your business network and its applications. When you connect a laptop to a WiFi hotspot at a caf...

What is a MAC Address? A MAC address, or Media Access Control address, is a 48- or 64-bit address associated with a network adapter. While IP addresses are associated with software, MAC addresses are linked to the hardware of network adapters. For this reason, the MAC address is sometimes called the hardware address, the burned-in address (BIA), or the physical address. MAC addresses are expressed in hexadecimal notation in the following format: 01-23-45-67-89-AB, in the case of a 48-bit address, or 01-23-45-67-89-AB-CD-EF, in the case of a 64-bit address. Colons (:) are sometimes used instead of dashes (-). MAC addresses are often considered permanent, but in some circumstances, they can be changed. There are two types of MAC addresses: Universally Administered Address The UAA, or Universally Administered Address, is the most commonly used type of MAC address. This address is assigned to the network adapter when it is manufactured. The first three octets define the manufacturer, whil...

Hubs, Bridges, Switches and Routers are used to build networks. If you are trying to design your own LAN (Local Area Network) at home, then you probably need to know what they do and the main differences between them. I will try to cover all that in addition to some networking details to cultivate the article and provide better understanding of how the internet works. After all, always remember that the internet as you know it is nothing more than a network of networks! Hubs are used to build a LAN by connecting different computers in a star/hierarchal network topology, the most common type on LANs now a day. A hub is a very simple (or dumb) device, once it gets bits of data sent from computer A to B, it does not check the destination, instead, it forwards that signal to all other computers (B, C, D…) within the network. B will then pick it up while other nodes discard it. This amplifies that the traffic is shared. There are mainly two types of hubs: 1. Passive: The signal is forwar...
