Computer Networking Fundamentals
A computer network is a collection of two or more computers with communication between them through a medium. The communication medium can be through radio waves, wires, infrared, optical fibers etc.
Computer network is an integral part of our daily lives, with the most important reason being that of communication. The use of computer networking is to share resources like fax machines, printers, modems, files etc., and its other uses are database server, computer server, email, chat, internet etc. The computer to which the resources are attached is called the server and the other computers that access the resource are called clients. In peer-to-peer computer networks there are no servers.
The sharing of fax machines, printers, and modems amongst many computers and users reduce the operational cost. A database on a computer network is a very important application as it stores and runs many important data and jobs. Emails and chats can be used for instantaneous communication and sending of files on a computer network.
The computer networks are classified, depending upon the size, as Local Area Networks (LAN), Wide Area Networks (WAN), Metropolitan Area Networks (MAN) and Personal Area Networks (PAN). The topology (topology is the way the computer networks and network resources are connected) of the networking can be classified as Bus Network, Ring Network and Star Network.
The networking hardware basically consists of wiring, network cards and a hub. Computer network cards are required so that one computer can understand what the other computer is "talking". Network cards have a unique MAC address to identify computers on a computer network. Hubs connect all the computers in the network. Hubs can also be used to connect to other hubs to increase the size of the computer network. Two computers can be connected using Ethernet cards or phone lines or power lines for communication, with hardware kits available at roughly a cost of $100.
As the number of computers in an office or a home increases, so do the number of cables, so wireless networking is a viable solution. In wireless networking radio transreceivers or infrared signals are used to communicate between computers and devices. Examples of wireless networking include Wi-fi and Bluetooth technology, though there may be security issues involved in wireless networking. However there definitely is a stronger preference towards wireless networking nowadays among consumers.
Computer networks have added a new dimension to the 21st century. Today the cyber world is much faster and wider than the real world. This has all been made possible due to computer networks. Computer networks have revolutionized business, communication, travel, research, defense, society and almost all human endeavors. The evolution of computer networks has helped the technological revolution take a big leap forward.

What is Critical Power?
Critical power is any form of power that if it were not available would have disastrous consequences.
What type of places would require continuous uninterruptible critical power supplies? Hospitals, Surgeries, Military Field operations, Banks, Airports, Space Bases, Communications networks, distribution centres, food manufacturing plants.
Surprisingly there are thousands of environments that require their to be always available 24-7 without any disruption, come hell or high water.
The only true way to protect critical power is with the installation of uninterruptible power supplies , known as UPS Systems which in turn are supported by Diesel Generators .
This system would then need to be made totally invincible to any power outage, however improbable or likely.
To achieve this, the UPS system and generator system would need to be replicated more than once in the event of mechanical failure. The term used is N+1 this equates to a double system. N+2 will be 200% cover and N+3 would be Triple cover.
Most Hospitals would protect their critical power with an N+3 power protection system.
An in depth understanding of how to protect critical power can be reviewed in the section on this website entitled, How does a disaster prevention system work?
How safe is the critical power at your office or business?
Most businesses today couldn't operate without their servers, so the perception that only hospitals require critical power is rapidly changing. Many now require total Disaster Prevention .
Any business should take the time to have any energy audit. Classify what is Critical, what is necessary and what you can do without. Then prioritise. Takes steps to protect your critical power before its gone.
The assumption that all power is critical power, so power downs will never occur is naive.
If you need critical power then protect it.
