700 Series Managed Switch User's Guide for Software v2.1 MD5 MD5 creates digital signatures using a one-way hash function, meaning that it takes a message and converts it into a fixed string of digits, also called a message digest. When using a one-way hash function, one can compare a calculated message digest against the message digest that is decrypted with a public key to verify that the message hasn't been tampered with. This comparison is called a "hashcheck." MDI/MDIX In cable wiring, the concept of transmit and receive are from the perspective of the PC, which is wired as a Media Dependant Interface (MDI). In MDI wiring, a PC transmits on pins 1 and 2. At the hub, switch, router, or access point, the perspective is reversed, and the hub receives on pins 1 and 2. This wiring is referred to as Media Dependant Interface - Crossover (MDI-X). See also Auto-negotiation. Multicast A single packet sent to a specific group of end stations on a network. NAT A technique by which several hosts share a single IP address for access to the Internet. NetBIOS Network Basic Input Output System. An application programming interface (API) for sharing services and information on local-area networks (LANs). Provides for communication between stations of a network where each station is given a name. These names are alphanumeric names, 16 characters in length. netmask Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router. A number that explains which part of an IP address comprises the network address and which part is the host address on that network. It can be expressed in dotted-decimal notation or as a number appended to the IP address. For example, a 28-bit mask starting from the MSB can be shown as 255.255.255.192 or as /28 appended to the IP address. Network Address Translation A technique by which several hosts share a single IP address for access to the Internet. packet A block of information sent over a network. A packet typically contains a source and destination network address, some protocol and length information, a block of data, and a checksum. Point-to-Point Protocol PPP. A protocol allowing a computer using TCP/IP to connect directly to the Internet. Glossary 7 SM-10004-02
