  • Network Load Balancing

    Network Load Balancing (NLB) is a clustering technology offered by Microsoft as part of all Windows 2000 Server and Windows Server 2003 family operating systems. NLB uses a distributed algorithm to load balance network traffic across a number of hosts, helping to enhance the scalability and availability of mission critical, IP-based services, such as Web, […]

  • DBCS

    Short for double-byte character set, a character set that uses two-byte (16-bit) characters rather than one-byte (8-bit) characters. Some languages, such as Chinese, Japanese and Korean, have writing schemes with many different characters that cannot be represented with single-byte codes such as ASCII and EBCDIC. In a single-byte character set, the possible number of binary […]

  • virtual camera

    In 3D animation, a virtual camera is a function of the animation software that works and behaves in the same way a camera or digital camera would in real-world situations. In the software, the virtual camera is made up from mathematical calculations that determine how the object will be rendered based on the location and […]

  • actuator

    The part of a hard disk to which the read/write arms attaches. All the heads are attached to a single head actuator, also called an actuator arm, that moves the heads around the platters. Older hard drives used a stepper motor actuator, which moved the heads based on a motor reacting to stepper pulses. Modern […]

  • Ultra ATA

    A version of the AT Attachment (ATA) standard that supports burst mode data transfer rates of 33.3 MBps. To take advantage of these high speeds, your computer must also be equipped with Ultra DMA, a protocol that supports faster data transfer rates to and from hard disk drives.

  • ActiveSync

    ActiveSync is Windows Mobile software that allows you to synchronize Windows Mobile and other Windows CE-based devices with a Windows-based PC or Exchange Server. If your PC is running Windows Vista, synchronization is managed through the Windows Mobile Device Center. For earlier versions of Windows, you can download ActiveSync.

  • row

    In spreadsheets, rows are numbered horizontal groups of cells. Contrast with column, which are vertical rows of cells, usually identified by letters.

  • Peskyspy

    Trojan.Peskyspy is a Trojan horse that has the capability to intercept calls – such as Skype or VoIP calls – record the audio and then store the file locally as an encrypted mp3 file and then relay it back to the cybercriminal. May also be referred to as a wiretap Trojan.

  • Geographic Information Systems (GIS)

    Short for Geographic Information Systems, tools used to gather, transform, manipulate, analyze, and produce information related to the surface of the Earth. This data may exist as maps, 3D virtual models, tables, and/or lists. GISs can be as complex as whole systems that use dedicated databases and workstations hooked up to a network, or as […]

  • GEO

    Short for geosynchronous, or geostationary, earth orbit, a satellite system used in telecommunications. GEOs orbit the earth at 22,300 miles above the earth’s surface. They are tied to the earth’s rotation and are therefore in a fixed position in space in relation to the earth’s surface. The satellite goes around once in its orbit for […]
