Capability computing

A small modern desktop or laptop computer might have 200 or more megabytes of ROM and 4 or 8 gigabytes of storage capability. Computer storage capacities are constantly increasing to keep pace with requirements for data storage and manipulation. 

Constructing increasingly sophisticated structural models for radicals in proteins remains a major challenge. To develop truly predictive capabilities, computational chemists must work to incorporate more realistic models of intermolecular contacts and to model the effects of molecular dynamics on... 

Parallel computers may also be distinguished based on whether they are allocated for capacity or capability computing, and this distinction is related to the commodity versus custom classification. Capacity computers are designed to obtain good throughput and high cost-effectiveness for running many small- to modest-sized jobs. Capability computers are reserved for...

Computers can function as powerful troubleshooting tools. Advanced technology systems, coupled with add-on interface cards and applications software, provide a wide range of testing capabilities. Computers can also be connected to many different instruments to provide for automated testing. There are two basic types of stand-alone automated test instruments (KTEs) functional and in-circuit. 

Since about 1960 a variety of newer mathematical and computational techniques have been introduced. These are sometimes called, collectively, modem control theory . Their application to industrial process control so far has been limited. This is pardy so b use few practitioners are familiar with the technology, and partly because it is not really appropriate for many applications. Study of control systems by these method requires a fairly capable computer on-line implementation usually also requires an on-line computer. Two of the best known approaches are the (1) multivariable ffequency-respcMise method, pioneered by Rosenbrock and associates in England, and (2) the state space or state variable approach, which has been popular for aerospace and military applications. 

Speed USB supports three bus speeds high speed (480 Mbps), frill speed (12 Mbps), and low speed (1.5 Mbps). Every USB-capable computer supports low and full speed. High speed was added in the version 2.0 USB specification.
