331 words - 2 pages protocol that, like TCP, runs on top of IP networks. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. Internet Protocol specifies the format of packets, also called datagrams, and the addressing scheme. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source. IP by itself is something like the postal system. It allows you to address a package and drop it in the system, but there's no direct link between you and the recipient. VIEW DOCUMENT

Dhcp Essay

490 words - 2 pages DHCP DHCP, an acronym for Dynamic Host Configuration Protocol, is a protocol used to automatically assign a unique IP address to a device. DHCP allows a computer to join an IP-based network without having a pre-configured IP address. DHCP is a protocol that assigns unique IP addresses to devices, then releases and renews these addresses as devices leave and re-join the network. DHCP is also used to configure the proper subnet mask, default gateway, and DNS server information on the device. A computer, or any other device that connects to a network (local or Internet), must be properly configured to communicate on that network. Since DHCP allows that configuration to happen automatically VIEW DOCUMENT
