Also called rotational delay, the amount of time it takes for the desired sector of a disk (i.e., the sector from which data is to be read or written) to rotate under the read-write heads of the disk drive. The average rotational latency for a disk is half the amount of time it takes for the disk to make one revolution. The term typically is applied to rotating storage devices, such as hard disk drives and floppy drives (and even older magnetic drum systems), but not to tape drives.
Short for Simple Object Access Protocol, a lightweight XML-based messaging protocol used to encode the information in Web service request and response messages before sending them over a network. SOAP messages are independent of any operating system or protocol and may be transported using a variety of Internet protocols, including SMTP, MIME, and HTTP.
A protocol for handling TCP traffic through a proxy server. It can be used with virtually any TCP application, including Web browsers and FTP clients. It provides a simple firewall because it checks incoming and outgoing packets and hides the IP addresses of client applications. There are two main versions of SOCKS — V4 and […]
- Small Office / Home Office(SOHO)
Short for small office/home office, a term that refers to the small or home office environment and the business culture that surrounds it. A SOHO is often thought of as being the smallest of small businesses. It is a privately owned and operated business or individuals who are self-employed. SOHO is often characterized as being […]
Short for silicon-on-insulator, a type of semiconductor fabrication technique developed by IBM. Unlike CMOS-based chips that are doped with impurities that enable a chip to store capacitance that must be discharged and recharged, SOI chips are formed by setting transistors on a thin silicon layer that is separated from the silicon substrate by an insulating […]
Short for Small Outline Integrated Circuit. A SOIC package is a leaded rectangular surface mount integrated circuit with eight or more gull wings leads, bent outwards at the tip. The leads are on two length sides of the package. SOIC packages are JEDEC compliant.
