Server
A host computer on a network, it houses information and responds to requests for information (for example, it houses Web sites and executes their links to other Web sites). The term "server" also refers to the software that makes the act of "serving information" possible. Commerce servers, for example, use software to run the main functions of an e-commerce Web site, such as product display, online ordering, and inventory management (you'll also hear this described as shopping cart technology). A server is the control computer on a LAN, meaning it controls the software, access to printers, and other parts of the network (usually accompanied by workstations that "share the load"). A server may be dedicated (where its sole purpose is to be the server) or non-dedicated (where in addition to being the server, it can be used for basic computing purposes).

switch
In telecommunications, it is a network device that selects a path or circuit for sending a unit of data to its next destination. A switch may also include the function of the router, a device or program that determines the route (and specifically, what adjacent network point) the data should be sent to. In general, a switch is a simpler and faster mechanism than a router, which requires knowledge about the network and how to determine the route.
On larger networks, the trip from one switch point to another in the network is called a "hop." The time a switch takes to figure out where to forward a data unit is called its "latency." The price paid for having the flexibility that switches provide in a network is this latency. Switches are found at the backbone and gateway levels of a network, where one network connects with another, and at the subnetwork level, where data is being forwarded close to its destination or origin.
A switch is not always required in a network. Many local area networks (LANs) are organized as rings (or buses) in which all destinations inspect each message and read only those intended for that destination.
