Unit 1 Task 4

Task 4 Functions:

Windows XP	Mac OS
The operating systems controls the whole machine and all the components in there. It also controls peripherals like keyboards, mouse, printers etc. For example Windows control monitor by changing the resolution, mouse by setting the click speed etc.	MacOS control of computer components are very similar, but almost all of devices need to be bought especially for Macs. For example MacOS can control keyboard by changing the input language. For other devices like iPhone MacOS controls screen by changing it to landscape mode.
Operating system needs to make sure that everything works properly and there is no unauthorised access that can harm your data. Windows has security functions like user accounts with password protection, crap firewall which is completely useless and other functions that can be easily bypassed by going to safe mode.	MacOS got security features like blocking the ports that are potential security issues. It also got security features that checks if the downloaded content is safe or not. In email programs attachments are not opened automatically so they can’t harm user computer without his knowledge.
Operating system needs to have file management to show files, create new files, deleting, editing and other functions linked to the files. Windows has his process called explorer.exe to handle the file management.	The program for file management that MacOS use is called Finder. It is pretty the same as Windows’ explorer, it got appropriate icon for every file type, the tree navigation system and trash on desktop.
Drivers are programs that tell the operating system what and how to do with this particular device. For example when you buy new graphic card, to make it work properly with all of its power and efficiency you need to install drivers provided with the card.	Same as Windows’, the drivers are programs that controls the devices. In MacOS case, when the system is closed and you can’t really upgrade anything, every needed driver to run the computer is included in system. But when you want to install new printer, you got to install version of driver for MacOS.

Windows XP

Mac OS

Some of the accessibility features in Windows can be added to earlier versions of those products, and to MS-DOS, through Access Packs. You can download these files from Microsoft. You also can use Control Panel and other built-in features to adjust the appearance and behavior of Windows to suit varying vision and motor abilities. These include adjusting colors and sizes, sound volume, and the behavior of the mouse and keyboard. The Accessibility Wizard helps you configure Windows for your vision, hearing, and mobility needs. Dvorak keyboard layouts make the most frequently typed characters more accessible if you have difficulty using the standard keyboard layout. There are three Dvorak layouts: one if you are a two-handed user, one if you type with your left hand only, and one if you type with your right hand only. You do not need to purchase any special equipment to use these features.

Control Panel- A programme on Windows that allows the user of the computer to access all the main settings of the computer including the drivers, screen settings and all the programmes in stalled on the computer.

System Tools-  These are things you can use in Windows to monitor/edit the settings and programmes on the computer. For example, there is the Task manager, disk cleanup and MSconfig.

Windows explorer- This is the main place of location for all of your folders. The windows explorer is the page where you can access on your computer. 

Dock- The dock is like the taskbar on windows, You can put all your favourite programmes and folders on your dock for easy access.

Time machine- This is a programme on Mac OS that allows the user of the computer to essentially "go back in time" to a previous point and restore the computer to the settings set at that point in time. Any programmes installed between the time of restore and the time you are restoring to will be erased, but any documents, like Microsoft word documents, you have created between the two times will remain on the computer.

System preferences- These are the main settings of the Mac. These preferences include: General settings, users and groups and Bluetooth.

Cover flow - This is an animated preview of documents and files in the Mac finder. This gives us a better view of the document before we open it to see if it is the document we want. It is particularly helpful if you are flicking through documents quickly.

Dashboard- This is the Mac equivalent of the Desktop in Windows. It holds many different programmes, files and folders and is the screen that first appears when you log in. You may call it the "home" of the computer.
