1. The Importance Of Computer Systems In The Modern World

   • Computers are extremely important in the modern world of today. In the fast moving life of the modern world of today, computers hold tremendous significance. Many of us will feel crippled without a computer, as we have gotten so used to this machine. The importance of computers can not be denied in the corporate or business world, at the work place and even in one's personal life.
   • Computers designed with higher levels of RAS have a multitude of features that protect data integrity and help them stay available for long periods of time without failure — this data integrity and uptime is a particular selling point for mainframes and fault-tolerant systems.
   • Make adequate backups. Your best security policy is to do frequent backups. So many times people have called me to say their system crashed - What should they do? I say, restore from backups. Backups? But what if I don’t have backups? Indeed. Most external External drives available today come with backup software that is economical and easy to use. Don't get caught without your backups

2. The Computer System

   • A computer system is a set of parts, including the computer itself, that work together to perform tasks. These tasks may be relatively simple, as in a calculator, or they may be very complex, as in air traffic control systems.
   • Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development.[2] A common type of systems modeling is function modeling, with specific techniques such as the Functional Flow Block Diagram and IDEF0. These models can be extended using functional decomposition, and can be linked to requirements models for further systems partition
   • Input Something goes in
     • Process Something Happening to it
     • Output Something Coming out

3. The Importance Of Ethical, Enviromental And Legal Considerations When Creating Computer Systems

4. The Need For Adherence To Suitable Professional Standards In The Development, Use and maintanace Of Computer Systems

   • In computing, standards are an agreed way of doing things. Standards make it easier for people to build programs and software that work on different systems in different countries. Standards affect many areas of computing, eg software files, formats and hardware. Some common standards include: MP3 - a file format for audio files supported by most media-playing software HTML - a markup language for creating websites Unicode - a form of representing text
