An interface that enables the serial (one bit at a time) exchange of data between two devices, one called a master and the other called a slave . An SPI operates in full duplex mode.

A device that transfers data between a computer serial port (COM port) and an Ethernet Local Area Network (LAN). 

An open standard for high-speed access to high-capacity disk storage. The standard is designed especially for networks, but can be used with smaller personal systems as well. 

A method used in accessing computer peripheral devices that employs a serial (one bit at a time) means of digital data transfer over thin cables. 

In information technology, a server is a computer program that provides services to other computer programs (and their users) in the same or other computers. 

A Peripheral Component Interconnect (PCI) card used to generate encryption keys for secure transactions on e-commerce Web sites.

SMB Protocol provides a method for client applications in a computer to read and write to files on and to request services from server programs in a computer network. 

A situation in which multiple, under-utilized servers take up more space and consume more resources than can be justified by their workload. 

The collection of software that forms the operational infrastructure on a given machine.  A server stack is one type of solution stack -- an ordered selection of software that makes it possible to complete a particular task.  

The masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users.
