Open the Start menu and type in control panel. 3. Once you have found the file you were looking for, you can obtain some additional information about the file by looking at its file properties. Troubleshooting can be a time-consuming and annoying procedure; fortunately, your operating system can fix this. As such, compressing them further does not help. Another potential problem that you might encounter is running out of storage space. Finally, we will look at some of the factors that may decrease a computers performance, as well as some potential solutions. Examples of problems that can be fixed using the troubleshooting wizards include network connection problems, printing problems and software compatibility problems. 4. d.Which of the following tabs is not found on the File Properties window? These include temporary files, the files in your Recycle Bin and the files used as part of a completed software upgrade. In order to prevent this from happening, close any application that you are not currently using. Since updates are so important for software, saying no to an update will cause the application to constantly remind (and annoy) you about the update, until you eventually allow it. Web cache: The web cache is a small area on a computers hard drive where images and pages from the world-wide web are stored for a short period. This can be solved by buying and adding additional RAM to your computer. Create subfolders within the root folder in order to distinguish between documents. The second factor is the amount of cores. This takes a few minutes to complete, but ensures that your computer is up to date with the newest software. endobj A mainframe computer uses multiple computer terminals that are connected to the main computer. 1.Write down the correct answer for each of the following questions. 1.Which of the following refers to cache located on the CPU? 189 0 obj

There are two important reasons for this: 1. In order to find out how a computer is using its resources, Windows operating systems have been designed to include an application called Task Manager. Not only does this waste time every time you open up a file; it uses up the space you saved when you compressed the files in the first place. To show the Disk Clean-up process, watch the following video: https://www.youtube.com/watch?v=5UfMKd3SPtY. 0000003508 00000 n

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 Browse for files or Browse for folders. When many files and folders are grouped together into a single file, they are said to be archived. x
When you open a website, such as Facebook, your computer temporarily stores the files for the website in your cache. This includes adding new features, fixing bugs, improving system reliability or security. 7. In order to help you with this process, lets take a look at some tips on effective file management: Modern operating systems allow you to import and export files, documents and data. As discussed previously in this chapter, fragmentation of data can cause your computer to slow down. As with processor speed, more cores are generally better. You will notice that the File Properties window consists of the following four tabs: Table 6.1: Tabs in the File Properties window, Example 6.1 Work with Read-only and Hidden files.

This will ensure that the document is in the correct folder and, therefore, can be found with more ease. This means that only a single person can use the computer at one time. Multitasking operating systems allow the computer to run multiple processes (tasks), or applications at the same time. In the Disk Clean-up application that opens up, select the types of files you would like to delete. In order to prevent this, you should delete documents and folders that are no longer needed. 0000004348 00000 n

Right click on the selected file to open the drop-down menu with options. By using separate processors for system and graphics processing, computers are able to handle graphic-intensive applications more efficiently. Sooner or later, you are going to encounter the problem of running out of hard-drive storage space. Type in disk clean-up and select Disk Clean-up. Because of this, the CPU is one of the most important components for determining how fast a computer will be. 0000005849 00000 n

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. 2.1Multitasking operating systems allow more than one user to access and use the computer system at the same time. 4. To find a file, you can use your computers search function.To search for a file, you can do the following: 2. To show the Disk Deframenter process, watch the following video: https://www.youtube.com/watch?v=AtRIOUZuI2c. b.List the positive outcomes of computer management. b.Which tab provides more information on which users are currently signed in to the computer and how many resources they are using?

The first is the GHz of the processor, which refers to the CPU frequency and is an indication of the processor speed. The Read-only attribute allows the user to view, but not edit the file. Your computer will calculate how much space you can free up. We use this information to present the correct curriculum and Old documents and folders can take up space and cause your computer to become cluttered. Lets take a look at some examples of file extensions: Folders refer to the location where the files are stored on your computer. Multiple-user operating systems allow more than one user to access and use the computer system at the same time. 3. (2), 4.3Mention TWO situations where your computer can run out of resources. Here the student will also learn the various computer trouble shooting methodologies. CPU cache: The difference in speed between a computers CPU and RAM has recently become too large. An example of this can be seen when you use your smartphone. Delete any files that you do not need any more. If the problems persist, you may have to buy a more powerful computer with more resources.

In order to prevent malware from infecting your computer, or to remove any malware that might already be installed on your computer, you can use security applications, such as a firewall, antivirus and anti-spyware. Rename the folder according to the contents of it. To prevent this problem, many CPUs now have a small, high-speed cache built into the CPU, where it can temporarily store the data it needs. e.How do you change the attribute of a file to enable yourself to edit the file?

As discussed in Chapter 5, malware has been designed to cause harm and use your computers resources without your knowledge. The operating system makes the users lives much easier by providing them with a user interface that can be used to interact with the computer. Click Save and run the backup option to create a backup of all your files. If you feel that you will need additional protection, Chapter 6 has some recommendations on which programs to buy. 3. Generally, the spool is maintained on the computers physical memory, buffers or the I/O device-specific interrupts.The spool is processed in ascending order, working on the basis of a FIFO (first in, first out) algorithm.The most common implementation of spooling can be found in typical input/output devices such as the keyboard, mouse and printer. <>
(1), 2.5CPU cache is high-speed memory stored on CPU that is larger than RAM. 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. Fragmentation occurs from files being constantly written, deleted and resized, and can lead to several problems. This is best illustrated when exporting your contacts from your smartphone and transferring the data to your Google account (this can also be used to back-up the data). 2. 5. b.List two reasons why file compression is rarely used. Troubleshooting wizards are system utilities that come standard with your operating system. To open the Task Manager, you can do the following: 1.
