Mobile computing allows access to the internet on the go through various devices such as laptops, PDAs, and cell phones. WiFi and cellular broadband are used for internet access, with cellular broadband being more mobile. Cloud computing and VPNs are also accessible through mobile computing. Mobile computing encompasses a range of portable technologies that make […]
Quantum computing is a new method of calculating that can perform multiple calculations simultaneously, making traditional computers seem limited. Quantum computers use qubits, which can hold values between 0 and 1, but stabilizing them is crucial. While exciting, quantum computing can also be dangerous if it falls into the wrong hands as it can decode […]
Parasitic computing uses other servers to provide computing power without breaching security. It can slow down legitimate computer activities and has ethical concerns. It is different from cluster computing and can be negative if infected with a virus or Trojan horse. Parasitic computing is a technique in which a computer or server connects to other […]
Parallel processing splits large tasks into smaller subtasks processed concurrently. Symmetric multiprocessing and multicore processing are examples of single device parallel processing. Distributed computing, computer clustering, and massively parallel computers link multiple devices for parallel processing. Multiprocessors are common in scientific and business applications, while clusters and massively parallel computers are used for advanced problems. […]
Cognitive computing involves developing computer systems that can think like a human brain by integrating technology and biology. It traces back to the 1950s, but the technology was limited until recent advances in cognitive science allowed for the development of neural networks. Intelligent computers are now being used in various industries, and researchers hope to […]
Computing platforms can be software or hardware frameworks from which software applications can be launched. They include GUIs, OSs, programming languages, and computer hardware architecture. Platforms ensure consistent performance and can allow software to run independently of the OS. Cross-platform applications are compatible with multiple OSs and achieved through the programming language used as the […]
Computer cookies are small text files that contain a unique ID tag placed on a computer by a website. They store information about a user’s activities on a website and can be temporary or permanent. Persistent cookies allow a site to recognize a user and track their browsing habits, leading to concerns about privacy. However, […]
Advanced computing can refer to high-end computers and processes, or to advanced computer skills. High performance computing (HPC) involves using supercomputers for complex simulations, such as in engineering or astrophysics. Advanced computer skills courses may cover topics like Photoshop or Windows operating systems. Programming and network configuration are not typically considered advanced computer usage. Power […]
Cloud computing architecture consists of interconnected servers, storage systems, and control nodes. The front-end is the client computer, and the back-end consists of application servers, data storage, and control nodes. APIs are used for communication, and redundancy is built into the data storage component. Application servers and control nodes are also important components. Cloud computing […]
Optical computing uses light instead of electricity to perform calculations, but requires more power over short distances. It has potential for large supercomputers and could be faster than current computers. Harvard researchers have found a way to flip a log using a single photon, a milestone for efficient optical computation. The technology is still in […]
