c)       NIC (Network Interface Card, Ex: LAN Cards)
d)      TCP/IP
e)      MEDIA (Cable ex: OFC, CAT5, CAT6)





Operating System




It is interface between user and hardware. We are having two types of operating system they are….
a)      Server OS
b)      Client  OS




Server OS


Server OS also called as Multiuser operating system and network OS.
Server operating system provides services.

a)      Windows NT (NEW Technology)
b)      Windows 2000 Server
c)       Windows Server 2003

NIC (Network Interface Card)
The Network Interface Card is frequently called a NIC. It forms and interface between the network device computer and the Ethernet (LAN).
Types of Cards used for connecting computers, with cables.
a)      BNC  (Bayonet Neill Concelman)
b)       NIC
i)                    Ethernet (Eth)
ii)                   Fast Ethernet (F Eth)
iii)                 Gigabit Ethernet (Giga Eth)
c)       W-NIC (Wireless NIC)


BNC  (Bayonet Neill Concelman / Banyan Network)
A type of connector used with coaxial cables such as the RG-58 A/U cable used with the 10Base-2 Ethernet system. The basic BNC connector is a male type mounted at each end of a cable. This connector has a center pin connected to the center cable conductor and a metal tube connected to the outer cable shield. A rotating ring outside the tube locks the cable to any female connector.


NIC (Network Interface Card)
A network interface controller (also known as a network interface card, network adapter, LAN adapter and by similar terms) is a computer hardware component that connects a computer to a computer network.


ETHERNET NIC

The Ethernet is a networking standard (known as IEEE 802.3) for Local Area Networks (LAN), which are used for connecting close-proximity devices together for sharing resources (such as in offices, schools, and homes). The Ethernet Network Interface Controller allows computing devices to take advantage of this technology, which has today become the ubiquitous medium for data transmission.

FAST ETHERNET

Fast Ethernet is a collective term for a number of Ethernet standards that carry traffic at the nominal rate of 100 Mbit/s, against the original Ethernet speed of 10 Mbit/s. Of the fast Ethernet standards 100BASE-TX is by far the most common and is supported by the vast majority of Ethernet hardware currently produced. Fast Ethernet was introduced in 1995.

GIGABIT ETHERNET

In computer networking, Gigabit Ethernet (GbE or 1 GigE) is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second (1,000,000,000 bits per second), as defined by the IEEE 802.3-2008 standard. It came into use beginning in 1999, gradually supplanting Fast Ethernet in wired local networks where it performed considerably faster. The cables and equipment are very similar to previous standards, and by the year 2010, were very common and economical.



Connecting Devices
a)      HUB
b)      Switch
c)       Router

HUB
It is generally used to connect all devices on a network so that they can communicate with each other. It always do broadcasting. An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment. It has multiple input/output (I/O) ports, in which a signal introduced at the input of any port appears at the output of every port except the original incoming. A hub works at the physical layer (layer 1) of the OSI model.

Switch
Like Hub, It is also used to connect all devices on a network so that they can communicate with each other. But first time it will do broadcast and from second time it will do unicast. A switch is a telecommunication device which receives a message from any device connected to it and then transmits the message only to the device for which the message was meant. This makes the switch a more intelligent device than a hub (which receives a message and then transmits it to all the other devices on its network.)
 Unicast – Unicast is communication between a single sender and a single receiver over a network.




Router
Router is a device which is used to established communication between two networks. A router is connected to two or more data lines from different networks. The routers are used in interconnected networks, the routers exchange information about destination addresses, using a dynamic routing protocol. Each router builds up a table listing the preferred routes between any two systems on the interconnected networks. A router has interfaces for different physical types of network connections, (such as copper cables, fiber optic, or wireless transmission).
