Week 8 Post - Parts of Network Systems
Network systems are important in today's tech-centered society. In reality, many of the common infrastructures we use would be crippled (at least for a short time) if something was to happen.
A network, usually internet based, is comprised of multiple devices that are interconnected. The devices can be any system that has the ability to connect to the internet. For a home network, devices connect to the internet through a router. The router is the host that sends and receives data to an external network (such as Walmart.com).
The two basic types of networks are the Local Area Network (LAN) and Wide Area Network (WAN). A LAN is a self-contained network that connects multiple devices together and is usually connected to the internet (World Wide Web). A step up from a LAN is the WAN. A WAN connects multiple LANs, in which the LAN is the “device” and the WAN is the self-contained network.
Businesses and some home networks use hubs and switches. Hubs and switches are used in LAN systems and enable multiple devices to connect to a single device by way of Ethernet cable. A switch is a hub with additional capabilities, such as bandwidth throttling.
The LAN, WAN, hub, and switch are only a few of many pieces that allow users to connect the internet, but they are some of the primary devices and systems. It is a good idea to have a basic understanding of network systems, which will allow a user to perform basic troubleshooting or report more detailed information to a specialist.
