"No Silver Bullet – Essence and Accidents of Software Engineering" is a widely discussed paper on software engineering written by Turing Award winner Fred Brooks in 1986.

Brooks argues that "there is no single development, in either technology or management technique, which by itself promises even one order of magnitude [tenfold] improvement within a decade in productivity, in reliability, in simplicity." He also states that "we cannot expect ever to see two-fold gains every two years" in software development, as there is in hardware development (Moore's law).

Computer hardware is the collection of physical components that constitute a computer system.

Computer hardware is the physical parts or components of a computer, such as monitor, keyboard, computer data storage, graphic card, sound card, motherboard, and so on, all of which are tangible objects.

By contrast, software is instructions that can be stored and run by hardware.

Computer software, or simply software, is that part of a computer system that consists of data or computer instructions, in contrast to the physical hardware from which the system is built.

In computer science and software engineering, computer software is all information processed by computer systems, programs and data.

Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.

Computer hardware and software require each other and neither can be realistically used on its own.

The user interface (UI), in the industrial design field of human–computer interaction, is the space where interactions between humans and machines occur.

The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators' decision-making process.

Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls.

The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.

In computing, an image scanner—often abbreviated to just scanner, although the term is ambiguous out of context (barcode scanner, CAT scanner etc)—is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image.

Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning.

Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.

Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical.
