Unit 2: Task 2: P2

Task 2 (P2)

Produce additional pages to explain the purpose of operating systems.

The presentation should contain screen shots or images and has to cover:

• machine and peripheral management
• security
• file management
• device drivers

Operating systems can either be installed via hardware or downloaded via the internet. It allows you to control your machine in many ways. Operating systems manage the computers memory, its processors, hardware and software. Operating systems help boot up your computer: this involves running tests to ensure everything is working correctly, it also checks for any new hardware on the system and starts up the computer. An example of an operating system is Windows. It will manage all the different programs at the same time so that everything will start up together and all at once. Different programs are capable of running at the same time, operating systems can be used with multi-users so that more than one individual may use the device.
                       
Computer security is a safe way of preventing any unorthodox software of data that may be harmful and trying to access the computer. It prevents any intruders or hackers from accessing your PC. All computer security software can detect intruders through a system scan that will scan all of your data and determine whether or not the risk is high enough to take action or whether the risk should be erased.  One form of security is internet security which is installed so that you can use the internet without any worry of losing any important or personal data. Due to the increase of individuals using the internet for things such as online banking ans shopping, you wish to be safe when involving your personal details as you don't want those to end up in the wrong hands. There are different types of internet security like Avast which allow you to use passwords to help protect all of your data and personal statements from things like cookies which use trackers. It is also better to avoid saving passwords and to always delete internet history so that no intruders can use cookie trackers to invade your computers operating system and files. You also need protection from Malware by using AntiMalware as Malware is malicious software that can result in viruses and Trojan horses that are severely dangerous toward your PC. To avoid Malware being a danger to your computer you need to run automatic updates on the AntiMalware software and to always have the firewall up for protection services. Also avoid opening any spam messages and to use and anti virus software like Microsoft which also has a AntiMalware software. Spyware is software that usually performs certain functions without your consent with things like the configuration of your computer and collecting your personal information without any of your knowledge. Spyware is difficult to remove and can slow down how fast your computer will run and to prevent this it is best to install software that prevents and monitors any spyware that may try to access your PC. Also for security it is best to keep the firewall on at all times as it prevents hackers, viruses and worms accessing your computer at any time when accessing the internet. 
                                                     

File management is the way of which data and files are stored on a device. File management allows you to locate files quickly and easily. it stores files in a specific way so that they are organised in storage and wont be lost. It uses storage units such as folders to secure files in specific locations within your device, if files are not organised without any methodical system or without backing theses files up it can take a lot of time to restore them corrupt files are capable of erasing a whole folder so it is best to back up all files to avoid losing them all together. File management is used via My Computer, My Computer allows you to access any data on your computer via the lists it displays with the various disc drives that are available. By entering one of these folders you are then capable of accessing the files that you are in need of. It is best to save files on a regular basis so that in any circumstance where your computer may just shutdown you will not lose any files/data. Files can also be imported and transferred onto a memory stick or even send an attachment to yourself via Email so you are certain you have the file.  

  

Machine and peripheral management. This controls the computers components, any device that is connected must be installed and can change the input language used when first installed onto the system. The operating system used e.g. Windows will control the whole machine and data stored in the system. The peripheral  management will control the functioning of the mouse, keyboard and printers which have to be connected and inserted into the ports within the tower. With machine management it will manage the properties of components such as the monitor and how it will display data and allows you to change its resolution and the speed of certain programs like the mouse and how quickly it will move. When a new peripheral is added the machine shall automatically install the device, then when installed corrections and changes can be made to the devices system and settings can be altered. 
 

Disc drivers are accessible and re writable storage devices and can be including the optical drive that accepts discs and the floppy disc. They can house the storage internally or externally, they read and write data and have a great performance rating. 
The (H:) drive is used to save any data to the Share drive  this can be any files or documents within the system that have been created and saved. The (F:) drive is used to save or read any data from a CD Rom or DVD that has been inserted into the optical drive to be viewed on the system. 
The optical disc drive that accepts CD's and DVD's reads them by retrieving the data, some USB sticks when connected to the tower can appear as its own disc drive so that data can either be imported and exported from the portable USB stick.
