Computer systems, compatibility with existing

If there is no restriction placed on the proposal by having to use the current in-house computer system, the choices of hard ware/software packages are numerous. The software must be user friendly, complementary to existing systems to avoid duplication of asset registering, etc., and have the facility to expand (i.e. have other programs (modules) that enable greater use be made of the information held within the system). The program should also be compatible with any in-house computer system where possible. 

The purpose of the present work is to claim that a third method exists in quantum chemistry for the dynamical conformational analysis of large molecules. We challenged that it would be possible to design such a new route by skilfully using a very simple micro-computing dynamic system in order to reduce the n-dimensional problem to a much smaller one, the size of which would be then compatible with the currently low budget of an academic laboratory. 

One special case exists for interrupts when configuring them. You will notice that some interrupts are cascaded to each other. What this means is that in an ISA system, when the computer needs to access an interrupt higher than 9, it uses IRQ 2 to get to it. This method ensures backward compatibility with 8-bit buses. 

Is the product compatible with the user s existing I/O devices If computer-based, can it be operated without a pointing device such as trackball or mouse Will it interface with a voice dictation system W at about speech output Can keystroke commands be entered sequentially For example, pressing the Control, Alternate, and Elelete buttons simultaneously is impossible for many people. - ... 

Preparing the software reqnirements is a process that is closely tied to designing the computer system. The software requirements describe what the software component must do in order that, when that software is executed on the chosen set of computers with associated peripherals, the overall system requirements are met. In the design of the compnter system, functionahty may be allocated in different ways between software and hardware to achieve an appropriate balance between such concerns as performance, cost, size, simphcity and compatibility. This will determine what the software reqnirements or hardware requirements will be. Specifiers should also be aware of the capabilities of the computers, tools and similar existing systems so that it is feasible to fulfil the software requirements in the software design and the software implementation. 

DOS 1. Acronym for Disk Operating System, an operating system originally developed by Microsoft for the IBM PC. DOS exists in two very similar versions MS-DOS, developed and marketed by Microsoft for use with IBM-compatible computers, and PC-DOS, supported and sold by IBM for use only on computers manufactured by IBM.
