Computational Complexity

Another point raised by RMIT University (2014) with regards to the components of computer operating system are:

• The system should have a good communication channel,

• Ability to accept user instructions,

• Graphic user interface

• Have good monitor screen

• Workable mouse

• File director

• Device drivers

• Memory administrator

• Scheduler

• Safeguarding systems are repaired frequently

• Install and update anti-virus software

• Install firewall

• Ensure proper configuration of monitor for adequate programming of task

• Employing user management measures to protect users’ interpretations and feedbacks

Another area of considerations according to Stiger (2003) is:

• Safety of the computer

• Procedural approach

• Inputting processes

• Maintenance culture must be maintained

• Level of reliability, privacy, and accessibility of the computer

• Protection against data and information in central processing unit

• Threats, viruses, worms, malware, ransomware, backdoor intrusions Stiger (2003) mentioned the following policies that are crucial with regards to computer operating system and they are:

• Suitability use policy

• Right of entry control policy

• Change organization policy

• Information security policy

• Incident response policy

4.0 SUMMARY

This unit analysed the various functions, processes, techniques, and components associated with computer operating system. The reason for using computer operating system can also be attributed to operations or activities in library and information centres. It was stated in this study unit that, the computer operating systems are used for the following purposes: process management, memory management, resource management security management, command interpreter, file management, dependable background for software implementation and instructions, communicable flow and workstation, diverse use of hardware resources, relationship among users and hardware, organisation of hardware mechanisms, provision of location for software functionalities, provision of data managing, monitoring of system functionality, availability of marketable operating system and various software compatibility. In light of this, the processes with how the user is prepared to operate the system begin with the starting of the systems. By this, you get the system ready for use, by make it to run for a while for proper functionality, before task are inputted for processing. When the document or information has been processed, wait for it to bring

out the result or output, then terminate or exit the system. There is need to ensure the system is properly shutdown, otherwise it might have adverse effect on the system when it is not properly terminated.

In the course of using the computer operating system, applying certain techniques are important This would enhance proper work processing, and quality assurance, through following the techniques below:

• Users’ awareness

• Time allocation

• Training and re-training

• Upgrade of system

• Job organization

• Cost of system maintenance

The components of the computer operating system have the following components:

• Process implementation

• Intersect

• Kernel

• Memory management

• Multitasking

• Networking

• Security

• Unser interface

• The system should have a good communication channel,

• Ability to accept user instructions,

• graphic user interface

• Have good monitor screen

• Workable mouse

• File director

• Device drivers

• Memory administrator

• Scheduler

The components of the computer operating systems, safe guide every operation, through taking precautions adhere to. The computer operating systems uses policy for safety measures for the longevity of the system. The precaution which must be adhere to are: followed judiciously.

• Safeguarding the systems are mandatory

• Installing and update of anti-virus software

• Install firewall

• Ensure proper configuration of the system through installing the appropriate window and software

• Employing user management measures to protect users’ interpretations and feedbacks

• Procedural approach

• Inputting processes

• Maintenance culture must be maintained

• Level of reliability, privacy, and accessibility of the computer

• Protection against data and information in central processing unit

• Threats, viruses, worms, malware, ransomware, backdoor intrusions This is in accordance with the following policy:

• Suitability use policy

• Right of entry control policy

• Change organization policy

• Information security policy

• Incident response policy

5.0 CONCLUSION

Based on the understanding that surrounds the functions, processes, techniques, components and policy of computer operating system, application of management principles to its sustainability become essential. This arises from the nature and support the systems gives to both individuals and organization, for execution of their goals and objectives. The functionality or roles of the computer operating system are evolving either in the past and present circumstances of activities in human endeavours. Therefore, the professional could complete their roles based on task before them.
