A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. Dick Morley is considered as the father of PLC as he had invented the first PLC, the Modicon 084, for General Motors in 1968.
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers are commonly made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. Many types of home computers or portable computers integrate all their functions onto a single printed circuit board.
In computing, ASPI is an Adaptec-developed programming interface which standardizes communication on a computer bus between a SCSI driver module on the one hand and SCSI peripherals on the other.
ExpressCard, initially called NEWCARD, is an interface to connect peripheral devices to a computer, usually a laptop computer. The ExpressCard technical standard specifies the design of slots built into the computer and of expansion cards to insert in the slots. The cards contain electronic circuits and sometimes connectors for external devices. The ExpressCard standard replaces the PC Card standards.
Automatic test equipment or automated test equipment (ATE) is any apparatus that performs tests on a device, known as the device under test (DUT), equipment under test (EUT) or unit under test (UUT), using automation to quickly perform measurements and evaluate the test results. An ATE can be a simple computer-controlled digital multimeter, or a complicated system containing dozens of complex test instruments capable of automatically testing and diagnosing faults in sophisticated electronic packaged parts or on wafer testing, including system on chips and integrated circuits.
PC/104 is a family of embedded computer standards which define both form factors and computer buses by the PC/104 Consortium. Its name derives from the 104 pins on the interboard connector (ISA) in the original PC/104 specification and has been retained in subsequent revisions, despite changes to connectors. PC/104 is intended for specialized environments where a small, rugged computer system is required. The standard is modular, and allows consumers to stack together boards from a variety of COTS manufacturers to produce a customized embedded system.
Toughbook is a line of rugged computers produced and marketed by Panasonic Corporation. The Toughbook, introduced in 1996 with the CF-25, is designed to withstand outside forces which would damage or destroy normal laptops. Toughbook mobile computers are used in a wide variety of industries, including construction, defense, emergency services, government, healthcare, law enforcement, manufacturing, oil, gas, telecom, and utilities. The Toughbook brand mainly competes with other lines of rugged computers, such as Dell's Rugged Extreme.
A rugged computer or ruggedized computer is a computer specifically designed to operate reliably in harsh usage environments and conditions, such as strong vibrations, extreme temperatures and wet or dusty conditions. They are designed from inception for the type of rough use typified by these conditions, not just in the external housing but in the internal components and cooling arrangements as well.
ETX, standing for Embedded Technology eXtended, is an integrated and compact 95 × 125 mm (3.7 × 4.9 in) computer-on-module (COM) form factor, which can be used in a design application much like an integrated circuit component. Each ETX COM integrates core CPU and memory functionality, the common I/O of a PC/AT, USB, audio, graphics, and Ethernet. All I/O signals as well as a full implementation of ISA and PCI buses are mapped to four high-density, low-profile connectors on the bottom side of the module.
A computer-on-module (COM) is a type of single-board computer (SBC), a subtype of an embedded computer system. An extension of the concept of system on chip (SoC) and system in package (SiP), COM lies between a full-up computer and a microcontroller in nature. It is very similar to a system on module (SOM).
COM Express, a computer-on-module (COM) form factor, is a highly integrated and compact computer that can be used in a design application much like an integrated circuit component. Each module integrates core CPU and memory functionality, the common I/O of a PC/AT, USB, audio, graphics (PEG), and Ethernet. All I/O signals are mapped to two high density, low profile connectors on the bottom side of the module. COM Express employs a mezzanine-based approach. The COM modules plug into a baseboard that is typically customized to the application. Over time, the COM Express mezzanine modules can be upgraded to newer, backwards-compatible versions. COM Express is commonly used in Industrial, military, aerospace, gaming, medical, transportation, Internet of things, and general computing embedded applications.
M-Systems Ltd., was a Nasdaq-listed Israeli producer of flash memory storage products founded in 1989 by Dov Moran and Aryeh Mergi, based in Kfar Saba, Israel. They were best known for developing and patenting the first flash drive, marketed in 1995 as DiskOnChip, and the first USB flash drive, marketed in 2000 as DiskOnKey. They also created the patented True Flash Filing System (TrueFFS) which presented the flash memory as a disk drive to the computer. After 17 years of business, they were acquired by their prior competitor, SanDisk, in 2006. The DiskOnChip (DOC) was developed at the R&D Center established by M-Systems called EUROM. Rick Iorillo, Rony Levy and David Deitcher were the individuals that worked on the development and marketing of the first 2 MB DOC. This product went on to receive the Most Innovative Award from EDN in 1995 and later went on to become the Flash Drive and DiskOnKey.

Embedded Platform for Industrial Computing (EPIC) is a computer form factor, a standard for an industrial-quality single-board computer, in use from about 2004 through 2016.
ESMexpress is a very compact computer-on-module (COM) standard. It is a complete processor module that currently supports several low-power Intel and PowerPC platforms. Apart from a CPU component, every module also includes memory and a range of serial communication interfaces such as PCI Express, Gigabit Ethernet, USB, SATA, SDVO, LVDS and HD audio. These interfaces are defined in the form factor's specification, and signals are assigned to two 120-pin connectors. This fixed pin mapping ensures that different ESMexpress modules can be exchanged more easily. Consequently, ESMexpress typically does not have an onboard FPGA. The idea behind this is to implement very specialized functions in an FPGA on the COM's carrier board to ease upgrades of the system CPU through exchange of the ESMexpress module.

Qseven, a computer-on-module (COM) form factor, is a small, highly integrated computer module that can be used in a design application much like an integrated circuit component. It is smaller than other computer-on-module standards such as COM Express, ETX or XTX and is limited to very low power consuming CPUs. The maximum power consumption should be no more than 12 watts.
