First Period- Intro to Tech
Computer Network- A network is a group of computers connected together that allows information to be exchanged between computers. There are many fundamental parts of a network.
Packet- A piece of a message transmitted over a packet switching network.One of the key features of a packet is that it contains the destination address.
Local Area Network (LAN)- Connects many devices that are close to each other, usually in the same building. Libraries that give book information connect over a local area network.
Wide Area Network (WAN)- connect a smaller number of devices that can be many kilometers apart. For example, if two libraries at the opposite ends of a city wanted to share their book catalog information, they would use of a wide area network.
Node- A node is anything that is connected to the network. While a node is typically a computer, it can also be something like a printer.
Media Access Control (MAC) address- physical address of any device of a network. The MAC address is made up of two equal parts.
IP address- Internet Protocol is an identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination.
Bus Topology- Each node is connected one right after the other along the same backbone, similar to Christmas lights. Information sent from a node travels along the backbone until it reaches its destination node.
Ring Topology- Rings have the nodes connected one right after the other. The end of the network comes back around to the first node, creating a complete circuit.
