- NIC (Network Interface Card) – a printed circuit board, adapter card or the underlying supporting chipset that snaps into the motherboard of a desktop PC, notebook or server and transmits and receives packets on a network. This card is used to connect to networks including a local area network (LAN).
- Wide Area Network (WAN) – a broadband network for high-speed cable modem or DSL-based Internet access or other dedicated Internet access service. The most commonly used NIC by small businesses is the 10/100Mbps Ethernet adapter.
- NOS (Network Operating System) – an OS designed for communications between networked computer systems. Popular NOS’s include Apple Mac OS, Linux, Microsoft Windows NT/2000 and Novell NetWare.
- Peer-to-Peer Network – an inexpensive alternative to a client/server network in which a PC doubles as both a workstation (used by an end user) and a server (from which resources are shared). Virtually any OS can be configured for peer-to-peer networking, but peer-to-peer networks are often assembled from Microsoft’s least expensive consumer OS’s, such as Microsoft Windows 98, Microsoft Windows Me and Microsoft Windows XP Home Edition.
- RAID (redundant array of independent disks) – technology generally used to increase a server’s reliability by simultaneously writing data to multiple hard drives. While many people also use RAID to improve server performance, RAID eliminates a single point of hard drive failure. Years ago, you could only get the benefits of RAID through SCSI-based hard drives. Today, IDE hard drives can also enjoy entry-level RAID fault tolerance benefits.
- SCSI (small computer systems interface) – a high-end interface for connecting both internal and external computer peripheral devices. Years ago, only SCSI-based storage devices were used in most servers.
- Server – any computing device or peripheral on a network designed to provide shared services and resources to network users. Servers are primarily characterized by multi-user usage, as compared to a desktop or notebook PC. Common servers are file, printer, e-mail messaging and collaboration, Web, proxy and database servers.
- Wireless Ethernet – set of standards and in-progress standards that allow Ethernet networks to run without physical cabling and utilize radio waves for transmission.
