Antivirus software installation on personal computersAntivirus software should be installed on each user’s device to search the memory and disk drives for viruses on a daily basis. An antivirus program looks for a virus signature, which is a fixed sequence of bytes that signals the existence of a specific virus. If the antivirus software detects a virus, it notifies the user and can disinfect, erase, or quarantine any files, folders, or disks that have been infected by the malicious code. Good antivirus software scans critical device files as the computer boots up, watches the computer for virus-like behavior on a continuous basis, scans drives, scans memory when a program is run, scans programs when they are downloaded, and scans email attachments until they are opened. Norton Antivirus from Symantec and McAfee Personal Firewall are two of the most commonly deployed antivirus security tools.
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.
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.
