MAJOR COMPONENTSN OF A COMPUTER
SOFTWARE
Are different from 2D computer graphics in that a three-dimensional representation of geometric data is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing. Despite these differences, 3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire frame model and 2D computer raster graphics in the final rendered display. In computer graphics software, the distinction between 2D and 3D is occasionally blurred; 2D applications may use 3D techniques to achieve effects such as lighting, and primarily 3D may use 2D rendering techniques.
3D computer graphics are often referred to as 3D models. Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences. A 3D model is the mathematical representation of any three-dimensional object (either inanimate or living). A model is not technically a graphic until it is visually displayed. Due to 3D printing, 3D models are not confined to virtual space. A model can be displayed visually as a two-dimensional image through a process called
HARDWARE
is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware. The hardware of a computer is infrequently changed, in comparison with software and data, which are "soft" in the sense that they are readily created, modified or erased on the computer. Firmware is a special type of software that rarely, if ever, needs to be changed and so is stored on hardware devices such as read-only memory (ROM) where it is not readily changed (and is, therefore, "firm" rather than just "soft").
Most computer hardware is not seen by normal users. It is in embedded systems in automobiles, microwave ovens, electrocardiograph machines, compact disc players, and other devices. Personal computers, the computer hardware familiar to most people, form only a small minority of computers (about 0.2% of all new computers produced in 2003). See Market statistics.
PEOPLEWARE
Peopleware is a popular book about project management. The first chapter of the book claims, "The major problems of our work are not so much technological as sociological in nature." The book approaches sociological or 'political' problems such as team 'jelling', quiet in the work environment, and the high cost of turnover.
The authors presented most subjects as principles backed up by some concrete story or other information. As an example, the chapter "Spaghetti Dinner" presents a story (fictional, but similar to true stories) of a manager inviting a new team over for dinner and then having them buy and prepare the meal as a team, in order to produce a first team success. Other chapters use real-life stories or cite various studies to illustrate the principles being presented...

The eMachines brand started life as a budget Internet sales PC company which flourished for a while but was snapped up in 2004 by Gateway. Its PCs are now sold through major retailers like PC World
