Computer Architecture
Published in Bogdan M. Wilamowski, J. David Irwin, Fundamentals of Industrial Electronics, 2018
Computers are often classified according to levels of integration. A mainframe computer is a large machine whose circuitry is typically contained on several circuit boards or cabinets of circuit boards. A microprocessor is an integrated circuit (IC) chip containing a complete CPU. Personal computers (PCs) are typically built around microprocessors and include a video display system, a keyboard for data entry, and disk drives for information storage. Common PC add-ons include printers; pointing devices, such as mice, track balls, and joysticks; CDROMs (compact disk read-only memory) and tape drives for mass storage of information; sound generators for multimedia applications; and modems and network interface hardware for communication with other computers. Engineering workstations are similar to PCs, although workstations are oriented more toward intensive graphics applications and networking.
Interconnection technology
Published in Stephen Sangwine, Electronic Components and Technology, 2018
All except the smallest of electronic systems are built up from subsystems or subassemblies that are in turn built from electronic components such as resistors, capacitors, transistors, integrated circuits (ICs), displays, and switches. A desktop personal computer, for example, is likely to be built from a power supply subsystem, a main circuit board, and a number of peripheral subsystems such as a CD/DVD drive and plugin memory modules. Small self-contained electronic products such as pocket calculators and portable phones are often built directly from components with no identifiable subsystems.
Information Systems for Managing Multiple Small Projects
Published in Richard E. Westney, Computerized Management of Multiple Small Projects, 2017
Personal computer (PC): A small computer intended for one user. Because the PC is entirely in the hands of its user, it offers the benefits of convenience and responsiveness which larger, more complex systems cannot match. The very low cost of the PC not only makes it easy to implement, but also means that the risks of developing a system are small, as the worst that can happen is that we scrap it and try again. It is because of these features of low cost, user convenience, and ease of implementation that PCs are a good candidate for small-project applications.
Maximal Marginal Relevance-Based Recommendation for Product Customisation
Published in Enterprise Information Systems, 2023
We use a PC recommender to test the viability and performance of our approach. We treat a PC as a combination of six components: the processor, monitor, hard disk, display card, memory and display driver. There are six component specifications for the processor, three for the monitor, three for the hard disk, three for the display card, four for the memory and five for the display driver.
