Redistribution( OSPF ,EIGRP ,RIP ) in Hindi

Hello Friends in this videos i am trying to create a connection between Three Routing protocols RIP, OSPF, EIGRP.

It is a very help full videos.It is a conspectus of  Redistribution

Networking Hardware components

Hello friends in this videos we are talking about networking hardware components

It is very helpful videos for a networking students.

there are many components in computer networking  like, LAN card, Modems, Switch ,Hub ,Router

what is IP addressing

Hello Friends in this videos We are talking about IP addressing version 4

It is very helpful videos for a beginner in networking/hacking world without I addressing 

any body not able create a network'

...........Must Watch......... 

Protocols

Hello friends in this videos we are talking about the Protocols. Protocols also important for networking stater this this video you will learn many things about the Protocols.In this i will also define about Some old protocols like IPX/SPX,   Net Bios    ,New link IPX/SPX  

Mainly now the day we are using TCP/IP protocols For this You can see my videos from my

Network Cables

Network Cables

 Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network.

This section will be divided into 2 major categories. Within these sections, each cable type will be discussed.

·         UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair)

·         Fiber Optic Cables

 Twisted pair cabling comes in two varieties: shielded and unshielded. Unshielded twisted pair (UTP) is the most popular and is generally the best option for school networks. The quality of UTP may vary from telephone-grade wire to extremely high-speed cable. Each pair is twisted with a different number of twists per inch to help eliminate interference from adjacent pairs and other electrical devices. The tighter the twisting, the higher the supported transmission rate and the greater the cost per foot. Although UTP cable is the least expensive cable, it may be susceptible to radio and electrical frequency interference (it should not be too close to electric motors, fluorescent lights, etc.). If you must place cable in environments with lots of potential interference, or if you must place cable in extremely sensitive environments that may be susceptible to the electrical current in the UTP, shielded twisted pair may be the solution. Shielded cables can also help to extend the maximum distance of the cables. STP cabling includes metal shielding over each individual pair of copper wires. This type of shielding protects cable from external EMI (electromagnetic interferences).

Fiber Optic Cables

Fiber optic cabling consists of a center glass core surrounded by several layers of protective materials. It transmits light rather than electronic signals eliminating the problem of electrical interference. This makes it ideal for certain environments that contain a large amount of electrical interference.

Fiber optic cables have the ability to transmit signals over much longer distances than coaxial and twisted pair. It also has the capability to carry information at vastly greater speeds. This capacity broadens communication possibilities to include services such as video conferencing and interactive services. The cost of fiber optic cabling is comparable to copper cabling.

The center core of fiber cables is made from glass or plastic fibers. A plastic coating then cushions the fiber center, and Kevlar fibers help to strengthen the cables and prevent breakage. The outer insulating jacket is made of Teflon or PVC.

There are two common types of fiber cables -- single mode and multimode. Multimode cable has a larger diameter; however, both cables provide high bandwidth at high speeds. Single mode can provide more distance, but it is more expensive.
