A widely connected public networks which transmits data using the packet switching mechanisms with the help of Internet Protocol (IP) (Forouzan, 2003). It can also be termed as network of networks that connects all the various networks in the world to access information. It connects the whole world and uses all standard protocols across all users. Key characteristics: • Uses the standard TCP/IP protocol for communication across the network. • Definition: • A widely connected public networks which transmits data using the packet switching mechanisms with the help of Internet Protocol (IP) (Forouzan, 2003).
It can also be termed as network of networks that connects all the various networks in the world to access information. It connects the whole world and uses all standard protocols across all users. • Key characteristics: • Uses the network resources to access information and facilities • Uses upper layer protocols to avail the required services • Security is always at risk as the huge network is quite difficult to monitor and maintain. • Quite economical in nature. Business setting: An enterprise can use internet to interconnect with other businesses or its own in connecting for information sharing and knowledge resources.
The business across geographical locations can interconnect with ease. It offers an inexpensive way to get connected and keep in synchronization with resources and events. Example: All large to medium to small E-Commerce businesses. Soaps Galore is a small shop in Waterville that sells handmade soaps, bath products and creams. A glowing review in the national magazine has flooded its office with phone calls all over the world. It created a website to host its products and services and sell over the internet.
Soaps Galore is using internet to facilitate all its customers to access their store online and purchase products. It has hosted a website in the internet so that anybody can access it from the public domain. Bloom Design Group is using internet to facilitate all its clients all over the world and designers to access products allows the designers to access company information. Comment: Internet has revolutionized communications over the internet and have ensured rise of various small businesses who cannot afford to spend exhaustively on marketing techniques.
It has also spread its influence over international markets and taps the resources online. 2. Intranet Definition It is a privately owned network that uses internet protocols to connect to each other. It is usually within a certain premise to interconnect all the network topologies to be implemented and connected. It is restricted to the business which implements it and not accessible to the public domain (Gardiner, 2005). It is usually hosted inside the organization which also protects its access outside the office network. Key characteristics • Within the business domain and specifically for the business only
• Incurs hardware for interconnecting and networking • Monitoring and management of the intranet is quite strong and secure • Security is strongly implemented for such networks with security privileges and stronger firewalls • Business data and information remains private and cannot be accessed from outside the network • Uses internet protocols for communication • Information retrieval is quite faster and effective Business setting use: Used for almost all businesses where information must be shared and the organization needs to keep in synchronization with resources.
The business information and access privileges are strong enough to prevent malicious access. Example: EMH Technologies Corporation has setup a site to facilitate its employees to view their personal human resource data from remote computers within the business. The site has an area where job postings can be viewed and can also apply through the site. EMH technologies is using intranet to facilitate its employees to access company information and charge their personal details. The site has been put up in the internal network.
Comment: Intranet has suitably extended an automation facility for various enterprise processes which has assisted the employees to perform activities in an automated fashion. The private network has interconnected the entire organization together to provide various services. 3. Extranet Definition It is a private network of an enterprise which uses the public network to interconnect each other for information access and sharing (Tanenbaum, 2003). It is wider than intranet but is a subset of internet. It is a way to connect with the external elements of a business for greater information access and sharing of resources.
It can be further framed into a private intranet connected with the internet. Key characteristics • It is a privately owned network to interconnect with external clients for access. • It is expensive in nature • Allows secure connection of business information to external agents for better synchronization of activities • Security of large extranets are quite complex in nature and there is always a threat to crucial business data • Faster communication is facilitated among customers and vendors for making faster business decisions
Business setting use: Used by businesses who desires to connect or requires connecting with its vendors, suppliers and manufacturers across vast geographical locations in a secured fashion so that communication of business information and data is provided in an effective manner. Example: XYZ Plastics is a manufacturing company with 50 plants located throughout the United States. They have a site which houses their employee personnel handbook, the contact information and addresses for all their plant locations and contact addresses of the employees.
The site also lets employees electronically submit leave applications and health benefits coverage. XYZ plastics is using extranet to provide services to all its employees in accessing their information and make necessary information. References / Bibliography Forouzan, A. Behrouz (2003).
