For assignment week 5,we had to identify the research problem on Operating System.It wasn’t an easy task because we had to find materials from google scholar,google books and also UKM research database.I spent 5 hours searching and searching then only can write the report..alhamdulilah,we managed to finish it although it was pretty hectic.
So,here is our report:
COMMON PROBLEMS OF OPERATING SYSTEM
In the previous assignment (week 4) my partner and I have already discussed and attached a document at our own Facebook Group regarding the topic of Operating System. In there, we introduced them specifically what is Operating System all about. However in this week assignment (week 5), we are focusing further on the common problems of operating system that we face whether directly or indirectly.
The common problems are:
SPYWARE. Spyware or also known as internet pop-up. Spyware is a category of program that tracks your activities on your computer, and then responds to your activities by opening up internet browsers to pages that may sell products that your surfing activities indicate you may be interested in.
Spyware gets in through finding holes in the Web Browser. The spyware taking up the computer maybe an ActiveX Control, a standalone executable browser that is loaded into the user’s computer when she or he visits the web containing spyware. Spyware can also installed itself and one of its vulnerability involves a cleverly coded Web Page, that is designed to fool the users into thinking that is a safe and trusted Web Page.
Another way is tagging along in e-mail. Email programs that displayed HTML email (such as Outlook and Mozilla Thunderbird) are often subject to the same vulnerabilities that have beset Microsoft Internet Explorers in recent years. The spyware get loaded sufficiently into the computer by display mail message. Apart from that, spyware gets in the computer by hiding in the software downloads. Many downloadable software or purchasing through online or over the counter contain spyware that are silently installed when you installed the program.
Spyware utilities are used to overcome spyware. For example, you can set up Firewall which can block anything suspicious or harmful. Another way is by using Lavasoft’s Ad-aware or Spybot that search and destroy spyware. You have to know that antivirus software isn’t enough to fight spyware because it can’t do the work of spyware utilities.
PROGRAM CRASHED REPEATEDLY. Operating system crash commonly occurs when a hardware exception occurs that cannot be handled. When encounter this kind of problem, you need to reboot your computer. Your program could keep crashing because your machine is in a bad state. Restarting the computer will ensure that the next time you start your program your machine will be in a proper state. It’s possible that some of your program’s resource files (dll’s, binary, xml, etc.) are corrupted or altered. The next step would be to try and reinstall the software that is causing the problems. For the best results, you will want to uninstall the current version you are running, and then reinstall the software from scratch. But you have to make sure to back up any saved files or data that you use with the program before you uninstall the program.
HARDWARE STOPS WORKING. Often, software or OS issues can cause hardware malfunctions. In order to fix these kinds of problems we will need to uninstall the device from the operating system, and then allow it to scan and reinstall the hardware for you.
The operating system is the most important type of system software in a computer system. Without an operating system, a user cannot run an application program on their computer, unless the application program is self booting. So, we have to take precautions in order to save our computer from facing this kind of problems like we stated above.

From this assignment,we learned something here:
- operating system is really important that we have to take a good care of our computer and prevent the system from crashing
- we must be careful when downloading something to avoid spyware (common mistake among the students)
ok,that’s all for week 5 :)
