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]
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

Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications [1] and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and ...
A server is a physical component to IT Infrastructure.. Information technology infrastructure is defined broadly as a set of information technology (IT) components that are the foundation of an IT service; typically physical components (computer and networking hardware and facilities), but also various software and network components.
An output device is any piece of computer hardware that converts information or data into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video. Examples include monitors, printers and sound cards.
The following outline is provided as an overview of and topical guide to information technology: . Information technology (IT) – microelectronics based combination of computing and telecommunications technology to treat information, including in the acquisition, processing, storage and dissemination of vocal, pictorial, textual and numerical information.
