El Capitan displaced Frontier as the world's fastest supercomputer in the 64th edition of the Top500 (Nov 2024). El Capitan is the third exascale system deployed by the United States and its primary purpose is to support the stockpile stewardship program of the US National Nuclear Security Administration.
An electronic hardware system, such as a multi-core processor, is called "monolithic" if its components are integrated together in a single integrated circuit.Note that such a system may consist of architecturally separate components – in a multi-core system, each core forms a separate component – as long as they are realized on a single die.
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
Because computer parts contain hazardous materials, there is a growing movement to recycle old and outdated parts. [66] 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.
A user presses a key which transfers information to a computer. In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. Examples of input devices include keyboards, computer mice, scanners, cameras, joysticks, and microphones.

The monolithic model differs from other architectures such as the microkernel [1] [2] in that it alone defines a high-level virtual interface over computer hardware. A set of primitives or system calls implement all operating system services such as process management , concurrency , and memory management .
HPE Frontier at the Oak Ridge Leadership Computing Facility is the world's first exascale supercomputer. Exascale computing refers to computing systems capable of calculating at least 10 18 IEEE 754 Double Precision (64-bit) operations (multiplications and/or additions) per second (exa FLOPS)"; [1] it is a measure of supercomputer performance.
