Similarly, individuals in different parts of the supply chain can communicate over networks without having to deal with the other members directly. For example, a retail clerk in a point of sale location can use a network to check supply quantity at a warehouse without ever talking directly to warehouse per- sonnel. If the item he needs is available, he can place an order directly from his terminal. The warehouse manager, in turn, can order more stock over a network from her supplier who, in turn, arranges for transportation for the stock through a network. The use of networks has changed the business model used by many organizations. Because network technology can speed or ease communications between individuals, departments, or busi- ness partners, it can be possible for management to eliminate functions from the organization and outsource them to other organizations that can do the task more cost-effectively. For example, a retailer may sell products directly to customers at a brick-and-mortar store, but may also sell to customers over the Internet. The retailer may also outsource the manufacturing of the products that it sells to other firms, and communicate with them over the Internet or other network. The retailer may out- source billing to yet another company and communicate with its bank through another network. Types of Networks LAN, MAN & WAN In general, a network is a set of locations (or nodes) with con- comitant hardware, software, and information that are linked together to form a system that transmits and receives information and data. There are three types of communications networks. Local area networks (LANs) connect multiple computers that are located near one another and linked into a network that allows the users to share files and peripheral devices such as printers, fax machines, and storage devices. LAN technology was devel- oped after the utility of personal computers for business became recognized and organizations wanted to be able to share infor - mation and access data for the organization. For example, a LAN may be used to link multiple workstations within a department as well as control a common printer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
