level, fixed source, particle transport Monte Carlo code for studying the attenuation and leakage of gamma ray photons in simple, multilayer, shielding configurations, originally written for serial computers, is modified and re-written to run efficiently on these two different types of parallel ...
Although some supercomputers are single computer systems, most are composed of multiple high performance computers working in parallel as a single system. The best known supercomputers are built by Cray Supercomputers. Supercomputers are different from mainframes. Both types of computers wield incredible ...
Computer science, the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information. The discipline of computer science includes the study of algorithms and dat
and it is still used in some parts of Asia. An abacus consists of a rectangular frame containing thin parallel rods attached with beads for counting. Who invented the laptop? Adam Osborne built the first laptop in 1981 and named it "Osborne 1." Back then, it was priced at nearly $2,...
There are many benefits of using hybrid computers. A few of those benefits are mentioned below. The computing speed of hybrid computers is very high. This is due to the all-parallel configuration of the analog subsystem. These computers help in online data processing. Hybrid computers can manage...
Companion viruses were more popular during the MS-DOS era. Unlike conventional viruses, they do not modify the existing file. Instead, they create a copy of a file with a different extension (such as .com), which runs in parallel with the actual program. ...
Parallel PortsAnother older port that is primarily used for connecting printers and other devices that are used for external storage; like serial ports, parallel ports are rarely found on modern computers. Parallel ports can send or receive 8 bits or 1 byte at a time. Parallel ports come in ...
Common types of desktop computer ports Let’s explore the most common types of ports you’ll find on desktop computers: USB ports USB (Universal Serial Bus) ports are the most versatile and commonly used connections on modern desktops. They come in several varieties: ...
Microprocessors typically have to store more data than can be held in a few registers. This additional information is relocated to special memory circuits.Memoryis composed of dense arrays of parallel circuits that use their voltage states to store information. Memory also stores the temporary sequenc...
processing units for handling various instructions in parallel in every processing stage. By using the above architecture, a number of instructions start execution within a similar clock cycle. These processors are capable of obtaining an instruction execution output of the above one instruction for ...
