simplex
Refers to transmission in only one direction. Note the difference between simplex and half-duplex. Half-duplex refers to two-way communications where only one party can transmit at a time. Simplex refers to one-way communications where one party is the transmitter and the other is the receiver. An example of simplex communications is a simple radio, which you can receive data from stations but can’t transmit data.

- simulation
The process of imitating a real phenomenon with a set of mathematical formulas. Advanced computer programs can simulate weather conditions, chemical reactions, atomic reactions, even biological processes. In theory, any phenomena that can be reduced to mathematical data and equations can be simulated on a computer. In practice, however, simulation is extremely difficult because most […]
- simultaneous multithreading
Abbreviated as SMT, simultaneous multithreading is a processor design technology that allows multiple threads to issue instructions each cycle. Simultaneous multithreading enables multithreaded applications to execute threads in parallel on a single multi-core processor instead of processing threads in a linear fashion.
- single-chip projector
Projectors using a single-chip produce color by spinning a wheel that contains red, green, blue and clear sections. This color wheel spins between the lamp and Digital Micromirror Device (DMD) to produce a composite full-color image. Contrast with three-chip projector which uses three DMDs.
- single-density disk
A low-density floppy disk. All modern floppies are double-density or high-density.
- single electron transistor
The single electron transistor or SET is type of switching device that uses controlled electron tunneling to amplify current. A SET is made from two tunnel junctions that share a common electrode. A tunnel junction consists of two pieces of metal separated by a very thin (~1 nm) insulator. The only way for electrons in […]
