Intranet and Extranet,Artificial Neural Networks,Server and Workstation

Intranet and Extra net

An Intranet is a private network

(LAN) that uses the TCP/IP protocol suite. However, access to the network is limited only to the users inside the organization.

The network uses application

programs defined for the global

Internet such as HTTP, and may

have web servers, print servers, file servers etc.

Extra net

Private network that uses the Internet protocol and the public telecommunication system

Shares part of a business's information with suppliers, vendors, partners, customers or other businesses.
Viewed as part of a company's intranet that is extended to users outside the company.


Artificial Neural Networks

ARTIFICIAL NEURAL NETWORKS

•Neural Networks can supplement the enormous potential of traditional computers with the ability to make sensible decisions and to learn by experience.

•Neural Computation is done by a dense mesh of computing nodes and connections. They operate collectively and simultaneously on data inputs.

•Antennas are being used to solve many real world problems. They have an ability to derive meaning from complicated or imprecise data and can be used to extract patterns and detect trends that are too complex to be noticed by either humans or other computer techniques


•Applications of neural networks, that give an impression of its achievements, include
(i) text to speech transformation
(ii) Picture data compression
(iii) recognition of handwriting
(iv) explosives detector
(v) signature examiner and many more.

Server and Workstation


Individual workstations (clients) have access to the resources available on the file servers.

Novell Netware and Windows NT Server are

examples of client/server network operating

systems.

Advantages of Server/Workstation

Resources and data security are controlled through the server.

Any or all elements can be replaced individually as needs increase.

New technology can be easily integrated into the system.

Server can be accessed remotely and across multiple platforms.


Disadvantages of Server/Workstation

Requires initial investment in dedicated server.

Large networks will require staff to ensure efficient operation.

When server goes down, operations will cease across the network.
