is a very small network used for communicating between personal devices. For example, a PAN may include a notebook computer, a wireless headset, a wireless printer, and a smartphone. A PAN is limited in range to only a few feet. A PAN is typically created using Bluetooth wireless technologies. Local Area Network (LAN) A local area network is a network in a small geographic area, like an office. A LAN typically uses wires to connect systems together. Wireless Local Area Network (WLAN) A wireless LAN covers an area that is roughly the same size as a standard LAN. However, it uses radio signals instead of wires to connect systems together. Metropolitan Area Network (MAN) A metropolitan area network is a network that covers an area as small as a few city blocks to as large as an entire metropolitan city. MANs are typically owned and managed by a city as a public utility. Be aware that many IT professionals do not differentiate between a wide area network and a MAN, as they use essentially the same network technologies. Wide Area Network (WAN) A wide area network is a group of LANs that are geographically isolated, but are connected to form a large internetwork. Management Network The term network often describes a computer system controlled by a single organization. This could be a local area network at a single location or a wide area network used by a single business or organization. If two companies connected their internal networks to

share data, you could call it one network. In reality, however, it is two networks, because each network is managed by a different company. Subnet A subnet is a portion of a network with a common network address. All devices on the subnet share the same network address, but they have unique host addresses. Each subnet in a larger network has a unique subnet address. Devices connected through hubs or switches are on the same subnet. Routers are used to connect multiple subnets. Internetwork A network with geographically disperse (WAN) connections that connect multiple LANs is often called an internetwork . Additionally, connecting two networks under different management is a form of internetworking, because data must travel between two networks. Participation Internet The Internet is a large, world-wide, public network. The network is public because virtually anyone can connect to it, and users or organizations make services freely available on the Internet. Users and organizations connect to the Internet through an Internet service provider (ISP). The Internet uses a set of communication protocols (TCP/IP) for providing services. Individuals and organizations can make services (such as a website) available to other users on the Internet. Intranet An intranet is a private network that uses Internet technologies. Services on an intranet are only available to hosts that are connected to the private network. For example, your company might have a website that only employees can access.

    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.
