Network Crash

In network environment lots of equipments take to make the connectivity between client and servers. Those equipments are transferring data each and every where in side the network. That data is transferring in data packet way.

In a huge network environment there is lots of equipment transferring lots of data packet at once. Some times some data packets are transferring very long distance inside the network and some times lot of data packet traveling inside one cable.

The summery of two paragraphs, the major point is considered about the data packet. We were preparing network Because of transferring data easily between the computers. We must considered about data packets and protect it. If we lost data mean network crash inside the network, in huge network this can be happen,

If we taking this example 1 picture there is a centralize HUB in that network. But the reason is with using HUB we can’t manage a network because it is not providing any traffic management in side the network.

And another point for the cables, if we take coaxial cable for this does this network it is not possible because inside the network environment magnetic affect, long distances can happen if we use coaxial for the ca balling some time data me be lost of that reason.

If the distances is higher we can’t transferring data because if range is high data might be lost by traveling. NIC is another major point is does the network. Because some NIC’s are not speed that mean it is not transferring large capacity of data packet that is a reason for lost the data.

Gigabit Ethernet

Before inception Xerox Corporation in 1970s, Ethernet has been the dominant networking protocol. If we take all protocols Ethernet has, by far, the highest number of installed ports and provides the greatest cost performance relative to token Ring, Fiber Distributed Data Interface (FDDI), and ATM for desktop connectivity. And those Ethernet provide their connectivity from 10 to 100 megabit per second (Mbps).

Gigabits Ethernet build on top of the Ethernet protocol that mean it provide it service speed increases by tenfold over. It is a logical choice for low-cost, high-performance network upgrade, providing unparalleled speed and ease of management. The Gigabit Ethernet provides speed from 1000 megabit per second or 1 gigabit per second (Gaps). This protocol performed high-speed connectivity like lightning; it is gaining more and more presence in the server connectivity market. Network administrators require higher network performance to cope with the increasingly data intensive applications, backup, and software distributions or desktop, educational system. Which is the one success point of the network connection; customers will be able to leverage their existing knowledge base to manage and maintain gigabit networks. In
future it will be more than one gigabit.
