Research Paper on:
Execution of Computer Software

Unformatted Sample Text from the Research Paper:
a PC operating system to a Unix-based system, we need to look at how the computer will understand the software and the commands if gives the computer. To understand this  we need to look at three many subjects; 1. The process by which the high-level software is converted to executable code, the way in which the executable code is loaded  into memory and run by the operating system and the low-level hardware operations involved in the execution of a sequence of instructions. The process by which the high-level software  is converted to executable code. When we consider the needs of the programme we will usually look at the way in which the user needs the functionality. WE consider  what the programme or application will undertake and how it will function in undertaking the different needs. However, we often do not consider how the programme or application itself manages  to achieve this. However, the process that the software need to undergo can be seen as a transformation of the many instructions that are written in a programming language, being  translated into instructions that can be understood by the operating system that it is to operate on. If we remember that the different operating systems have completely different architecture, then  in looking at how the language a programme is written in, and how it is translated, we will understand more accurately why it will need to be adapted for different  operating systems. The more complex the programme the hard it will be to write. This is why high level languages were developed, although harder to use, they reduce the  amount of time needed to writer a programmes and the number of lines needed. Languages such as COBOL, C and RPG are all high level languages (Anonymous, 2002) Once an
