To make these functions easier to understand, they will be grouped into different categories based on their goals. 0000001489 00000 n It can be initiated by hardware such as a button press, or by a software command. 0000031265 00000 n This process reorganises your hard drive by taking all the pieces of data that are spread across your hard drive and reorganising it so that the pieces are closer to each other. 0000005849 00000 n 189 0 obj << /Linearized 1 /O 191 /H [ 920 569 ] /L 554354 /E 25458 /N 18 /T 550455 >> endobj xref 189 22 0000000016 00000 n 9 0 obj 0000002592 00000 n d.Describe how cache improves performance. b.Which of the following file extensions are NOT part of the Microsoft Office package? The Scheduling Utility is located in the System ribbon menu. 0000001128 00000 n Due to this, the operating system has a large number of different functions and jobs. It stores data that is being sent or received by the hard-disk plates for a short period of time. The central processor of a computer is also known as the CPU, or central processing unit. This processor handles all the basic system instructions, such as processing mouse and keyboard input and running applications. Click and open the File Explorer options. This includes checking for updates, looking for and downloading messages and emails, and making sure you are connected to an internet-enabled network. Some common GUIs are the ones associated with Microsoft Windows, Mac OSX, Chrome OS, GNOME, KDE, and Android.e into memory before it can be executed. In other words, it needs to ensure that theappropriate number of resources is allocated to the processes, as well as the correct hardware is activated when required. 2.1Multitasking operating systems allow more than one user to access and use the computer system at the same time. Compression is, however, useful to archive files. Connect your external hard drive to your computer. CPU cache: The difference in speed between a computers CPU and RAM has recently become too large. 0000008687 00000 n These categories consist of the following: Microsofts Windows 10 operating system is estimated to be made up of around 50 000 000 lines of code. Lets take a look at some examples of file extensions: Folders refer to the location where the files are stored on your computer. to personalise content to better meet the needs of our users. You can do this, by clearing the Read-only checkbox in the File Properties window. 0000007481 00000 n Multitasking operating systems allow the computer to run multiple processes (tasks), or applications at the same time. In order to obtain these improvements, the user needs to update the software, or download a patch from the suppliers website. 3. Give a reason for your answer. By using separate processors for system and graphics processing, computers are able to handle graphic-intensive applications more efficiently. File management utilities provide users with a GUI that they can use to organise files and folders. The last thing you want is for your computer to spend half the time playing music and the other half running your game. 0000002389 00000 n Change the underlined word(s) to make the statement true.

Table 6.2: Tabs in the Task Manager window. In todays competitive market, computer programmers continue to improve their software after they have been released. An example of this can be seen when listening to music while you are playing games. 2. Correct the statement if it is false. An example of this can be seen when you are browsing the internet. At the end of this chapter you should be able to: In this chapter, we will look at what an operating system is and why it is important in managing programs. 6. To find a file, you can use your computers search function.To search for a file, you can do the following: 2. <> 233 0 obj << /Linearized 1 /O 235 /H [ 1128 1306 ] /L 489960 /E 151705 /N 55 /T 485181 >> endobj xref 233 34 0000000016 00000 n 6.

In other words, it is made up of 50 000 000 lines of instructions that tell it how to do its job. (1), 2.3The write-only attribute allows the user to view but not edit the file. Most desktop computers contain a CPU developed by either Intel or AMD, both of which use the x86 processor architecture. e.How do you change the attribute of a file to enable yourself to edit the file? Under Advanced Settings, click Show hidden files, folders and drives. Fragmentation occurs from files being constantly written, deleted and resized, and can lead to several problems. As a result, the RAM cannot provide all the information the CPU needs fast enough. Once the Disk Clean-up tool has identified the files, it lets you decide which files can be deleted. Because of this, these operating systems are normally used as server. Compressed files cannot be used immediately; they first need to be decompressed.

Disk cache: The disk cache is a small amount of RAM that is built into a hard-disk drive. The Read-only attribute allows the user to view, but not edit the file. Files refer to any document that you have created; including text documents, spreadsheets, images and music. Besides the central processing unit, most desktop and laptop computers also include a GPU. 0000004208 00000 n An example of this can be seen when you use your smartphone. This is all thanks to the operating system. Data is sent to and stored in memory or other volatile storage until the program or computer requests it for execution.Spool is technically an acronym for simultaneous peripheral operations online.Spooling works like a typical request queue or spool where data, instructions and processes from multiple sources are accumulated for execution later on. Describe the role of the operating system. e.Which application do you use to find out how the computer is using its resources? Otherwise, select the folders that should be backed up manually. This will open the Control Panel. Choose a term or concept from Column B that matches a description in Column A. These background services allow your smartphone to check for messages, update your applications and manage your cellular network all at the same time. Troubleshooting can be a time-consuming and annoying procedure; fortunately, your operating system can fix this. 2. (1), 1.3When a computer is started up the operating system is loaded into the _______. However, it will still be limited to only one active user. 3. One of the reasons why your smartphones battery goes flat, even when the screen is turned off and you are not using it, is that your CPU is still running tasks. To open the File Properties window, you can do the following: 1. For each application currently running, the amount of available resources will become less.
