Computer hardware contain dangerous chemicals such as lead, mercury, nickel, and cadmium. According to the EPA these e-wastes have a harmful effect on the environment unless they are disposed of properly. Making hardware requires energy, and recycling parts will reduce air pollution, water pollution, as well as greenhouse gas emissions. [67]
SystemC is an example of such—embedded system hardware can be modeled as non-detailed architectural blocks (black boxes with modeled signal inputs and output drivers). The target application is written in C or C++ and natively compiled for the host-development system; as opposed to targeting the embedded CPU, which requires host-simulation of ...
The BBC Computer Literacy Project 2012 was an initiative to develop students' marketable information technology and computer science skills. Computer programming skills were introduced into the National Curriculum in 2014. [19] [20] It was reported in 2017 that roughly 11.5 million United Kingdom citizens did not have basic computer literacy ...
A microprocessor, ASIC, or expansion card designed to offload a specific task from the CPU, often containing fixed-function hardware. A common example is a graphics processing unit. accumulator A register that holds the result of previous operation in ALU. It can be also used as an input register to the adder. address
Examples of operational technology include: Programmable logic controllers (PLCs) Supervisory control and data acquisition systems (SCADA) Distributed control systems (DCS) Computer numerical control (CNC) systems, including computerized machine tools; Scientific equipment (e.g. digital oscilloscopes)
Intel introduced the 8087, 80187, 80287 and 80387 math coprocessors to add hardware floating-point and transcendental function capabilities to the 8086 through 80386 CPUs. The 8087 works with the 8086/8088 and 80186/80188, [ 58 ] the 80187 works with the 80186 but not the 80188, [ 59 ] the 80287 works with the 80286 and the 80387 works with the ...

For example, in a single computer system, this would be the computer's architecture, operating system (OS), and runtime libraries. [2] In the case of an application program or a computer video game , the most relevant layer is the operating system, so it can be called a platform itself (hence the term cross-platform for software that can be ...
