Every now and then we come across terminology that leaves us scratching our heads as to the meaning of certain acronyms, buzzwords or new IT terms emanating from our friends at Redmond (or Reading!). With this in mind, we've put together a glossary of terms for you to use, print off or cut-n-paste to your desktop which will help you sort out your ASPs (Active Server Pages) from your ASPs (Application Service Provider).

OSPF Open Shortest Path First (OSPF), one of two dynamic routing protocols that Windows 2000 (Win2K) supports, provides an efficient but complex dynamic routing mechanism in mid- to large-sized networks. Unlike Routing Information Protocol (RIP) routers, OSPF routers keep a map of the network that updates whenever there's a change in the network topology. OSPF divides the network into areas connected to each other by a backbone area. Each router keeps track of link state databases for adjacent areas. Connecting the backbone area to other areas is the responsibility of area border routers (ABRs).
PKCS Also known as personal information exchange format (PFX), Public Key Cryptography Standards (PKCS) #12 is an industry standard format for backing up and restoring certificates and their private keys. Windows 2000 (Win2K) supports PKCS #12 and other cryptography standards such as PKCS #7 and PKCS #10 as part of the Public Key Infrastructure (PKI). PKCS #12 lets you transport certificates and their keys from one computer to another, or from a computer to a removable media. This standard supports the transfer of certificates between products from the same or different vendors.
PKI Public Key Infrastructure (PKI) is a term that describes the standards, policies, and software components that manage certificates. Electronic transactions use PKI with digital certificates and certificate authorities to verify and authenticate participants. PKI offers a strong authentication mechanism and simplifies administration because it lets you issue certificates (which you can map to user accounts in AD) instead of passwords. PKI deployment secures exchange of information over public networks such as the Internet. You can transfer data securely using Secure Sockets Layer (SSL), Transport Layer Security (TLS), or Secure MIME (S/MIME).
Round robin Round robin is a technique that DNS uses to distribute a load among multiple hosts. When a client sends a query to the DNS server for a host that contains multiple resource records, the server round robins (rotates) the order of IP addresses in the responses.
