Software

Computer softwareSoftware & Programmingsoftware technology
By contrast, software is instructions that can be stored and run by hardware.
This is in contrast to physical hardware, from which the system is built and actually performs the work.

Firmware

BadUSBflashingflash
Intermediate between software and hardware is "firmware", which is software that is strongly coupled to the particular hardware of a computer system and thus the most difficult to change but also among the most stable with respect to consistency of interface.
In computing, firmware is a specific class of computer software that provides the low-level control for the device's specific hardware.

Computing

A combination of hardware and software forms a usable computing system, although other systems exist with only hardware components.
It includes development of both hardware and software.

Computer

computerscomputer systemdigital computer
Computer hardware includes the physical, tangible parts or components of a computer, such as the cabinet, central processing unit, monitor, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms. The progression from levels of "hardness" to "softness" in computer systems parallels a progression of layers of abstraction in computing.
A "complete" computer including the hardware, the operating system (main software), and peripheral equipment required and used for "full" operation can be referred to as a computer system.

Computer memory

This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms.
In computing, memory refers to a device that is used to store information for immediate use in a computer or related computer hardware device.

Case modding

case modcase modderscasemod
Hobbyists may decorate the cases with colored lights, paint, or other features, in an activity called case modding.
Modding is done, particularly by hardware enthusiasts, to show off a computer's apparent power by showing off the internal hardware, and also to make it look aesthetically pleasing to the owner.

Input/output

I/Ooutputinterface
This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms.
I/O devices are the pieces of hardware used by a human (or other system) to communicate with a computer.

Computer data storage

A system monitor is a hardware or software component used to monitor system resources and performance in a computer system.

BIOS

ROM BIOSSystem BIOSBasic Input/Output System
The term BIOS (Basic Input/Output System) was created by Gary Kildall and first appeared in the CP/M operating system in 1975, describing the machine-specific part of CP/M loaded during boot time that interfaces directly with the hardware.

Motherboard

Computer hardware includes the physical, tangible parts or components of a computer, such as the cabinet, central processing unit, monitor, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.
A 2003 study found that some spurious computer crashes and general reliability issues, ranging from screen image distortions to I/O read/write errors, can be attributed not to software or peripheral hardware but to aging capacitors on PC motherboards.

Computers emit this electrical power as heat generated by all major components.

Output device

Graphical output deviceoutputoutput devices
Input and output devices are typically housed externally to the main computer chassis.
An output device is any piece of computer hardware equipment which converts information into human-readable form.

Input device

Input and output devices are typically housed externally to the main computer chassis.
In computing, an input device is a piece of computer hardware equipment used to provide data and control signals to an information processing system such as a computer or information appliance.

Personal computer

PCPCspersonal computers
The personal computer, also known as the PC, is one of the most common types of computer due to its versatility and relatively low price.
Computer hardware is a comprehensive term for all physical and tangible parts of a computer, as distinguished from the data it contains or operates on, and the software that provides instructions for the hardware to accomplish tasks.

Upgrade

upgradingsoftware upgradeupgradable
When using computer hardware, an upgrade means adding new hardware to a computer that improves its performance, adds capacity or new features.
In computing and consumer electronics an upgrade is generally a replacement of hardware, software or firmware with a newer or better version, in order to bring the system up to date or to improve its characteristics.
