- in-memory metabase
An image of the Internet Information Services (IIS) metabase that has been loaded from disk into the computer s RAM memory and is used while IIS is running. See also metabase.
Internet Server API (ISAPI) extensions that are hosted in the worker process address space. See also Internet Server Application Programming Interface (ISAPI).
- independent software vendor (ISV)
A third-party software developer; an individual or an organization that independently creates computer software.
When referring to software, to add program files and folders to your hard disk and related data to your registry so that the software runs properly. Installing contrasts with upgrading, where existing program files, folders, and registry entries are updated to a more recent version.
When referring to hardware, to physically connect the device to your computer, to load device drivers onto your computer, and to configure device properties and settings.
See also device driver; registry; upgrade.
A set of change and configuration management features based on Active Directory that enables management of user and computer data and settings, including security data. IntelliMirror also provides limited ability to deploy software to Windows 2000 and later workstations or servers. See also Active Directory.
In networking, a logical device over which packets can be sent and received. In the Routing and Remote Access administrative tool, it is a visual representation of the network segment that can be reached over the LAN or WAN adapters. Each interface has a unique name .
- Interior Gateway Routing Protocol (IGRP)
A distance vector IP routing protocol developed by Cisco Systems, Inc. See also Internet Protocol (IP).
- Internet Authentication Service (IAS)
The Microsoft implementation of a Remote Authentication Dial-In User Service (RADIUS) server, which provides authentication and accounting for network access, and proxy, which provides forwarding of RADIUS messages. See also Remote Authentication Dial-In User Service (RADIUS); service; virtual private network (VPN).
- Internet Control Message Protocol (ICMP)
A required maintenance protocol in the TCP/IP suite that reports errors and provides simple diagnostic capabilities. ICMP is used by the Ping tool to perform TCP/IP troubleshooting. See also Internet Protocol (IP); protocol; Transmission Control Protocol/Internet Protocol (TCP/IP).
- Internet Engineering Task Force (IETF)
An open community of network designers, operators, vendors , and researchers concerned with the evolution of Internet architecture and the smooth operation of the Internet. Technical work is performed by working groups organized by topic areas (such as routing, transport, and security) and through mailing lists. Internet standards are developed in IETF Requests for Comments (RFCs), which are a series of notes that discuss many aspects of computing and computer communication, focusing on networking protocols, programs, and concepts.
- Internet Group Management Protocol (IGMP)
A protocol used by Internet Protocol version 4 (IPv4) hosts to report their multicast group memberships to any immediately neighboring multicast routers. See also protocol.
- Internet Information Services (IIS)
Software services that support Web site creation, configuration, and management, along with other Internet functions. Internet Information Services include Network News Transfer Protocol (NNTP), File Transfer Protocol (FTP), and Simple Mail Transfer Protocol (SMTP). See also File Transfer Protocol (FTP).
- Internet Key Exchange (IKE)
A protocol that establishes the security association and shared keys necessary for two parties to communicate by using Internet Protocol security (IPSec). See also Internet Protocol security (IPSec); protocol.
- Internet Protocol (IP)
A routable protocol in the TCP/IP protocol suite that is responsible for IP addressing, routing, and the fragmentation and reassembly of IP packets. See also packet; Transmission Control Protocol/Internet Protocol (TCP/IP).
- Internet Protocol security (IPSec)
A set of industry-standard , cryptography-based protection services and protocols. IPSec protects all protocols in the TCP/IP protocol suite except Address Resolution Protocol (ARP). For virtual private network (VPN) connections, IPSec is used in conjunction with Layer Two Tunneling Protocol (L2TP). See also Layer Two Tunneling Protocol (L2TP); protocol; Transmission Control Protocol/Internet Protocol (TCP/IP); virtual private network (VPN).
- Internet Server Application Programming Interface (ISAPI)
An application programming interface (API) that resides on a server computer for initiating software services tuned for Windows operating systems.
In Microsoft Provisioning System, ISAPI resides on the Web server.
See also application programming interface (API).
- Internet service provider (ISP)
A company that provides individuals or companies access to the Internet and the World Wide Web. An ISP provides a telephone number, a user name, a password, and other connection information so users can connect their computers to the ISP s computers. An ISP typically charges a monthly or hourly connection fee.
- Internetwork Packet Exchange (IPX)
A network protocol native to NetWare that controls addressing and routing of packets within and between local area networks (LANs). IPX does not guarantee that a message will be complete (no lost packets). See also local area network (LAN).
A network within an organization that uses Internet technologies and protocols, but is available only to certain people, such as employees of a company. Also called a private network . See also network.
- IP address
For Internet Protocol version 4 (IPv4), a 32-bit address used to identify an interface on a node on an IPv4 internetwork. Each interface on the IP internetwork must be assigned a unique IPv4 address, which is made up of the network ID, plus a unique host ID. This address is typically represented with the decimal value of each octet separated by a period (for example, 192.168.7.27). You can configure the IP address statically or dynamically by using Dynamic Host Configuration Protocol (DHCP).
For Internet Protocol version 6 (IPv6), an identifier that is assigned at the IPv6 layer to an interface or set of interfaces and that can be used as the source or destination of IPv6 packets.
See also Dynamic Host Configuration Protocol (DHCP); Internet Protocol (IP); scope.
