what is a function of an extranet
Weegy: An extranet is a computer network that allows controlled access from the outside, for specific business or educational purposes. [ In a business-to-business context, an extranet can be viewed as an extension of an organization's intranet that is extended to users outside the organization, usually partners, vendors, and suppliers, in isolation from all other Internet users. In contrast, business-to-consumer (B2C) models involve known servers of one or more companies, communicating with previously unknown consumer users. An extranet is similar to a DMZ in that it provides access to needed services for channel partners, without granting access to an organization's entire network. ] (More)

what are the benefit when maintaning a secure network
Weegy: It reflects the organizational structure. Organizations may be distributed across a wide geographic area. It is natural for databases to be set up to reflect this. [ Local areas will keep local information and this allows local users to quickly access the local database. A headquarters may also wish to make global inquiries to local data at the local regions. Improved shareability. This allows users at one site to access data stored at other sites. Data is placed close to the users who normally access this data, it gives them local control and allows them to set up and establish local policies regarding the data use. A global administrator is responsible for the entire system and should help at a local level to develop and manage the dbms. Improved availability and reliability. Data in a centralized DB is inaccessible if there is a problem with the DB. However i a distributed site the local data is only inaccessible and if replication is i force then all data may be available at another site. Improved performance. Since data is kept local then local access is much quicker than access to a centralized DB. Read more: ] (More)
