A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid.
A computer case, also known as a computer chassis, is the enclosure that contains most of the hardware of a personal computer. The components housed inside the case (such as the CPU, motherboard, memory, mass storage devices, power supply unit and various expansion cards) are referred as the internal hardware, while hardware outside the case ...
Inside of a laptop, with the CPU removed from socket. Since microprocessors were first introduced they have almost completely overtaken all other central processing unit implementation methods. The first commercially available microprocessor, made in 1971, was the Intel 4004, and the first widely used microprocessor, made in 1974, was the Intel ...
In computer architecture, a bus (historically also called a data highway [1] or databus) is a communication system that transfers data between components inside a computer or between computers. [2] It encompasses both hardware (e.g., wires, optical fiber) and software, including communication protocols. [3]
a local computer bus for attaching hardware devices in a computer and which is part of the PCI Local Bus standard personal computer (PC) Any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end user, with no intervening computer operator.
The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster.
An all-in-one computer (also called an AIO or all-in-one PC) is a type of personal computer that integrates the computer components, such as the CPU, monitor, and speakers, into a single unit. It occupies a smaller footprint than a desktop computer with a tower form factor , and also uses fewer cables.
