Fundamentals of Computer Systems

1. The importance of ethical, environmental, and legal considerations whilst creating computer systems

   • Ethical Considerations
   • Environmental Considerations
     • Computers use a lot of electricity to run, and use just as much too coll themselves down.
     • People who sell computer systems are designing ways to keep the computer cool, without using as much electricity. They have started introducing 'sleep' and 'hibernation' modes , so as to keep the cost of electricity down.
   • Legal Considerations

2. Importance of Computer Sysytems in the modern world

3. The need for adherence to suitable standards in devlopment,use, and maintenance of computer systems

4. The Computer System

   • Software
     • Computer software is a set of 'machine-readable' instructions that directs a computers processor to perfrom specific operations
   • Operating Systems
     • An operating system is a type of software that manages computer hardware and software resources, and provides services for computer programs
   • Hardware
     • Computer hardware is the physical components of a computer system, such as the mouse, the monitor, and the keyboard
   • A basic computer model is made up of hardwares and softwares such as; a C.P.U board(hardware), apllication software, system softaware, operating software, and monitors , mice, keyboards, and hard-drives(hardware)
   • The Input and Output Process
     • Input process
       • Puts information into the system, using input devices
     • Output process
       • Displays results on output devices
