That is the reason behind the birth, which is a familiar device today - the LAN and WAN - networks of computers that are connected. This ensures that data within the group is sure to have this more optimal use of space and ease of sharing. One need not go physically to a foreign subsidiary to the computer to look there, the grid allows access to all those who belong to this network.
What server?
But as these networks be managed?It would be chaos when hundreds of computers had to be physically connected by wires and the wires are not crossed over oceans anyway. Therefore, we have servers - whose job it is to manage a network of computers. Server can use all kinds of activities, or they can be dedicated to only one type of work. A file server, for example, stores the data files belonging to a specific grid. Microsoft Exchange Server is dedicated, for example, to only useBusiness-mails and other means of communications such as official business IM accounts. Multi-processor server edit tasks simultaneously, keep several of the Internet is connected, storing data, managing mailboxes, etc. These are complicated programs rather than a computer and have much the same function in a large scale as our humble OS on any home PC.
Used the server
Servers have been created for better management of data and make it faster andsafer for all users. All of us deal with servers in any format or the other. Some of the most common utilities of servers:
• Provision of access to the Internet. Most of us a server provided by a company that creates web accessibility, availability and services for us. This makes it cheap and easy for us to stay connected through the network.
· Management of the official release. Almost all the offices run on a LAN server now connects allthe computers and manage them centrally. This is the office infrastructure makes it cheaper, easier, safer and better managed.
°, so that remote access. As in the example above, one must not travel to Germany to see there at the computer, it can be right here in the UK access to a server that connects the two systems.
· Daily services such as ATMs and travel arrangements from the respective companies are all subject to serversfor services rendered.
· Entertainment has made its foray in the server also to remotely now with movies distributed on a common server.
Types of servers
The list above is just the tip of the iceberg. The servers are of many types, and new ones are created or customized to meet customer needs every day. Some of the types of servers that are very familiar to us are listed below:
· Chat Server:All of us are with net chat rooms, Instant Messenger and all types of live forum activities. These are all thanks due to servers.
· Fax Servers: Another common feature of most offices and a blessed relief from the extremely high phone bills, but a source for obtaining the document on paper.
· FTP server: One of the oldest formats that these secure file transfer between networked systems.
• GroupServer, be it the Internet or intranet office and connects multiple computers in a virtual space made by these servers.
Hard drives in servers
Hard drives are now household goods, and the definition of the disks inside servers is affected by this changed scenario. A 60GB hard drive can also act as a server now. But the most common format is the RAID - an array of hard drives - which is explained below.
What is RAID?
RAID stands for Redundant Array ofIndependent Disks and is self-explanatory. It is literally a "stack" of two or more drives with a special disk manager to run it. RAIDs are rated on a scale of 1 to 10, to measure the efficiency and usefulness. There are also RAID 53 and RAID 0 +1, which are very powerful array.
Data Loss from server drives
Data loss can happen from servers, and by natural disasters, viruses and hacker attacks, logical errors, disk crashes, electrocutionhuman error or mishandling.
RAID Solutions for Data Loss
RAID data loss recovery professionals attended to best data. Any company that has experienced loss of data only a RAID (or is on the edge of a) must immediately an established company for data recovery.
