Study Notes

Software Development Process

The software development process follows the Software Development Life Cycle (SDLC), which consists of several stages: preliminary investigation, system analysis, system design, system tool acquisition, implementation, and system maintenance.
Preliminary investigation determines the problems that need to be fixed by the system software and identifies better solutions.
System analysis investigates the problem on a large scale, gathers information, and identifies the execution environment and interfaces required by the software.
System design creates a blueprint of the system software, specifying its look and performance.
System tool acquisition decides on the software tools to develop the system software's functionalities.
Implementation builds the software using the chosen tools, with all the functionality, interfaces, and support for execution.
System maintenance involves updating the software after installation.

Recent Trends in Software Development

Recent trends in program development include the use of preprocessors, JavaScript MV* frameworks, CSS frameworks, SVG, and gaming frameworks.
Other trends include the development of single-page web apps, mobile web apps, and the use of cloud services.
There is a shift towards using GPU over CPU, and agile development is becoming more popular.

Levels of System Software

System software includes operating systems, utility programs, disk defrag, firewall, and target machine code.
Other levels of system software include loaders, linkers, debuggers, library programs, language translators, and assemblers.

System Software Life Cycle

The life cycle of system software includes compile time, distribution time, installation time, link time, load time, and run time.
At compile time, the source code is translated into machine code and checked for errors.
Distribution time sends or distributes the program from the creator to the user.
Installation time makes the program ready for execution within the system.
Link time links the specific implementation of the interface to the program.
Load time takes the executable image from storage and places it into active memory for execution.
Run time is the final stage of the system software life cycle.
