Numerical value, notation, and units The speed of light in vacuum is usually denoted by a lowercase c, for "constant" or the Latin celeritas (meaning 'swiftness, celerity'). In 1856, Wilhelm Eduard Weber and Rudolf Kohlrausch had used c for a different constant that was later shown to equal √ 2 times the speed of light in vacuum. . Historically, the symbol V was used as an alternative symbol ...
Tibet (/tɪˈbɛt/ ⓘ; Tibetan: བོད, Lhasa dialect: [pʰøːʔ˨˧˩] Böd; Chinese: 西藏; pinyin: Xīzàng), or Greater Tibet, is a region in the central part of East Asia, covering much of the Tibetan Plateau and spanning about 2,500,000 km2 (970,000 sq mi). It is the homeland of the Tibetan people. Also resident on the plateau are ...

Early computers such as the ENIAC had to be physically rewired to perform different tasks, which caused these machines to be called "fixed-program computers". The "central processing unit" term has been in use since as early as 1955. Since the term "CPU" is generally defined as a device for software (computer program) execution, the earliest device...
The fundamental operation of most CPUs, regardless of the physical form they take, is to execute a sequence of stored instructions that is called a program. The instructions to be executed are kept in some kind of computer memory. Nearly all CPUs follow the fetch, decode and execute steps in their operation, which are collectively known as the inst...
Hardwired into a CPU's circuitry is a set of basic operations it can perform, called an instruction set. Such operations may involve, for example, adding or subtracting two numbers, comparing two numbers, or jumping to a different part of a program. Each instruction is represented by a unique combination of bits, known as the machine language opcod...
Most modern CPUs have privileged modesto support operating systems and virtualization. Cloud computing can use virtualization to provide virtual central processing units (vCPUs) for separate users. A host is the virtual equivalent of a physical machine, on which a virtual system is operating. When there are several physical machines operating in ta...
The performance or speed of a processor depends on, among many other factors, the clock rate (generally given in multiples of hertz) and the instructions per clock (IPC), which together are the factors for the instructions per second (IPS) that the CPU can perform.Many reported IPS values have represented "peak" execution rates on artificial instru...
