ICT : Reasons For Choice Of Language

ICT : Reasons For Choice Of Language

1. Organisational Policy

   • Some companies (particularly large ones) have an organisational policy as to what computer hardware and software is to be used.
     • Example
       • A company might have a policy to use only Microsoft software because of the level of support that may provided by such a large software vendor.

2. Suitability in terns of features and tools

   • Some programming languages were create for different types of applications They have features that support the different types of applications.
     • Example
       • Military application sofware such as missile guidence tends to be written in languages such as Ada.

3. Availability of trained staff

   • In a commercial programming environment, the programmers who work for a particular company may already be skilled in using a particular language so that language may be the natural choice for a new project .
     • Example
       • For a project where staff need to be recruited to complete the programming, it should prove easier to recruit staff for a popular language rather than a less widely used one.

4. Reliability

   • Some programming languages have features built into them which help make programs more reliable and less likely to crash.
     • Example
       • The best example of this is the Ada Language, it was designed from the outset to include features which make it relible.

5. Development and maintenance cost

   • Clearly, the cost of developing and maintaining programs is and important consideration when embarking to a Software development project.
     • Example
       • In 1980s, report program generator (RPG) was specifically designed to allow the speedy creation of reports.

6. Expandability

   • Some Software systems have to support hundreds or even thousands of simultaneous users.
     • Example
       • Systems written for interactive websites for example, may need to support a very large number of users without crashing.
