A basic definition of Intranet an Intranet can be viewed as a small Internet which resides on company or private LANs or local area networks. Or you can say Intranet is a computer network that is designed to work like the internet but in a much smaller scale and is restricted only to the employees of the company. It is possible to run FTP, HTTP, and mail servers in the intranet that is independent and inaccessible from the internet without proper authorization. This allows the employees to send progress reports to their manager even when they cannot meet in person. Workers could also work collaboratively on a certain project while keeping their paperwork properly synchronized. It is often necessary to have access to the internet from within your intranet, which is why intranets are placed behind a firewall.
The internet is the massive network of computers from all around the world. It allows people to virtually any point in the world at a very minimal cost. Services like Email and VoIP has allowed many people to keep in touch despite geographical locations and time zones.
Being connected to the internet, a company can have their people in the field or those who are working at home to still be able to do what they would usually do when they are inside the office. They can connect to services inside the intranet and submit their work or contact their coworkers and superiors.
Basic difference of intranet and internet are follows
• Users differ. Intranet users are your own employees who know a lot about the company, its organizational structure, and special terminology and circumstances. Internet is used by customers or users who will know much less about your company and for seeking knowledge also care less about it.
• The tasks differ. The intranet is used for everyday work inside the company, including some quite complex applications; the Internet site is mainly used to find out information about products or info..
• The type of information differs. The intranet will have many draft reports, project progress reports, human resource information, and other detailed information, whereas the Internet site will have marketing information and customer support information and general info.
