Formfactor
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard. It may also define an entire system, as in a computer form factor. Evolution and standardization As electronic hardware has become smaller following Moore's law and related patterns, ever-smaller form factors have become feasible. Specific technological advances, such as PCI Express, have had a significant design impact, though form factors have historically evolved slower than individual components. Standardization of form factors is vital for hardware compatibility between different manufacturers. Trade-offs Smaller form factors may offer more efficient use of limited space, greater flexibility in the placement of components within a larger assembly, reduced use of material, and greater ease of transportat ...

Small Form Factor (desktop And Motherboard)
Small form factor (SFF) is a classification of desktop computers and for some of their components, computer case, chassis and motherboard, to indicate that they are designed in accordance with one of several standardized form factor (design), form factors intended to minimize the volume and footprint of a desktop computer compared to the standard ATX form factor. For comparison purposes, the size of an SFF case is usually measured in litres. SFFs are available in a variety of sizes and shapes, including shoeboxes, cubes, and book-sized PCs. Their smaller and often lighter construction has made them popular as home theater PCs and as gaming computers for attending LAN parties. Manufacturers also emphasize the aesthetic and ergonomic design of SFFs since users are more likely to place them on top of a desk or carry them around. Advancements in technology combined with a reduced size enables a powerful computer to be a smaller size. Small form factor designs do not include computing ...

Computer Case
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 (typically cable-linked or plug-and-play devices such as the display, speakers, keyboard, mouse and USB flash drives) are known as ''peripherals''. Conventional computer cases are fully enclosed, with small holes (mostly in the back panel) that allow ventilation and cutout openings that provide access to plugs/sockets (back) and removable media drive bays (front). The structural frame ( chassis) of a case is usually constructed from rigid metals such as steel (often SECC — steel, electrogalvanized, cold-rolled, coil) and aluminium alloy, with hardpoints and through holes for mounting internal hardware, case fans/ coolers an ...

Motherboard Form Factor
In computing, the motherboard form factor is the specification of a motherboard – the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc. Specifically, in the IBM PC compatible industry, standard form factors ensure that parts are interchangeable across competing vendors and generations of technology, while in enterprise computing, form factors ensure that server modules fit into existing rackmount systems. Traditionally, the most significant specification is for that of the motherboard, which generally dictates the overall size of the case. Small form factors have been developed and implemented. Overview of form factors A PC motherboard is the main circuit board within a typical desktop computer A desktop computer, often abbreviated as desktop, is a personal computer designed for regular use at a stationary location on or near a desk (as opposed to a portable computer) due to its size and power requirements.

Motherboard
A motherboard, also called a mainboard, a system board, a logic board, and informally a mobo (see #Nomenclature, "Nomenclature" section), is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and computer memory, memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the CPU, the chipset's input/output and Memory controller, memory controllers, interface (computing), interface connectors, and other components integrated for general use. Nomenclature ''Oxford English Dictionary'' traces the origin of the word ''motherboard'' to 1965, its earliest-found attestation occurring in the magazine ''Electronics (magazine), Electronics''. The term alludes to its importance and size compared to the components attached to i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Port (hardware)
A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment. This is a non-standard term. Electronically, the several conductors where the port and cable contacts connect, provide a method to transfer data signals between devices. Bent pins are easier to replace on a cable than on a connector attached to a computer, so it was common to use female connectors for the fixed side of an interface. Computer ports in common use cover a wide variety of shapes such as round ( PS/2, etc.), rectangular (FireWire, etc.), square ( Telephone plug), trapezoidal ( D-Sub — the old printer port was a DB-25), etc. There is some standardization to physical properties and function. For instance, most computers have a keyboard port (currently a Universal Serial Bus USB-like outlet referred to as USB Port), into which the keyboard is connected. Ph ...

Clamshell Design
Clamshell design is a form factor commonly used in the design of electronic devices and other manufactured objects. It is inspired by the morphology of the clam. The form factor has been applied to handheld game consoles, mobile phones (where it is often called a "flip phone"), and especially laptop computers. Clamshell devices are usually made of two sections connected by a hinge, each section containing either a flat panel display or an alphanumeric keyboard/ keypad, which can fold into contact together like a bivalve shell. Generally speaking, the interface components such as keys and display are kept inside the closed clamshell, protecting them from damage and unintentional use while also making the device shorter or narrower so it is easier to carry around. In many cases, opening the clamshell offers more surface area than when the device is closed, allowing interface components to be larger and easier to use than on devices which do not flip open.

Notebook (laptop)
A notebook computer or notebook is, historically, a laptop whose length and width approximate that of letter paper (). The term ''notebook'' was coined to describe slab-like portable computers that had a letter-paper footprint, such as Epson's HX-20 and Tandy's TRS-80 Model 100 of the early 1980s. The popularity of this form factor waned in the middle of the decade, as larger, clamshell-style laptops offered far more capability. In 1988, NEC's UltraLite defined a new category of notebook: it achieved IBM PC compatibility, making it technically as versatile as the largest laptops, while occupying a letter-paper footprint in a clamshell case. A handful of computer manufacturers followed suit with their own notebooks, including Compaq, whose successful LTE achieved full feature parity with laptops and spurred many others to produce their own notebooks. By 1991, the notebook industry was in full swing. Notebooks and laptops occupied distinct market segments into the mid-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laptop
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 design, clamshell form factor (design), form factor with a flat-panel computer screen, screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is in the lower part, under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers. Laptops are used in a variety of settings, such as at work (especially on business trips), in education, for PC game, playing games, Content creation, content creating, web browser, web browsing, for personal multimedia, and for general P ...

Disk Enclosure
A disk enclosure is a specialized casing designed to hold and power hard disk drives or solid state drives while providing a mechanism to allow them to communicate to one or more separate computers. Drive enclosures provide power to the drives therein and convert the data sent across their native computer bus, data bus into a format usable by an external connection on the computer to which it is connected. In some cases, the conversion is as trivial as carrying a signal between different connector types. In others, it is complicated enough to require a separate embedded system to retransmit data over connector and signal of a different standard. Factory-assembled external hard disk drives, external DVD-ROM drives, and others consist of a storage device in a disk enclosure. Benefits Key benefits to using external disk enclosures include: *Adding additional storage space and media types to Small form factor (desktop and motherboard), small form factor and laptop computers, as ...

Hard Disk Drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating hard disk drive platter, platters coated with magnetic material. The platters are paired with disk read-and-write head, magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual Block (data storage), blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small disk enclosure, rectangular box. Hard disk drives were introduced by IBM in 1956, and were the dominant secondary storage device for History of general-purpose CPUs, general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portable Computer
A portable computer is a computer designed to be easily moved from one place to another, as opposed to those designed to remain stationary at a single location such as desktops and workstations. These computers usually include a display and keyboard that are directly connected to the main case, all sharing a single power plug together, much like later desktop computers called '' all-in-ones'' (AIO) that integrate the system's internal components into the same case as the display. In modern usage, a portable computer usually refers to a very light and compact personal computer such as a laptop, subnotebook or handheld PC, while touchscreen-based handheld ("palmtop") devices such as tablets, phablets and smartphones are called mobile devices instead. The first commercially sold portable computer might be the MCM/70, released 1974. The next major portables were the IBM 5100 (1975), Osborne's CP/M-based Osborne 1 (1981) and Compaq's , advertised as 100% IBM PC ...
