What Is an Operating System? Your computer runs two different types of software—application software and system software. You are probably most familiar with application software. This type of software includes word processing, drawing, spreadsheets, and other applications. The operating system (OS) is system software that is installed on a computer to control and organize its component parts—memory, hardware, and software. Most of the computers used in businesses come with an OS already installed. The most commonly used operating systems are the Windows series. Other commonly used OS’s include Macintosh and Linux. All the devices shown below have something in common. Do you know what that is?

Although the computer is the device most commonly associated with operating systems, other items are controlled by operating systems as well. Emerging technologies such as MP3 players, cell phones, and personal digital assistants all have operating systems. What Does an Operating System Do? The OS is the boss of your computer—it is in charge of everything your computer does. Without an OS, a computer would be a useless machine. The main functions the OS provides include:

• displayingtheGraphical User Interface (GUI); • managingapplicationsoftware; • coordinatingtheinteractionofhardwareand

software; • handlingdatastorageandretrieval.

GUI. The OS’s of most computers used in businesses, schools, and the home function in a graphical user environment that makes it relatively simple for people to interact with their computers. In the early days of computers, the computing environment was much less user-friendly. Computers were controlled in a command-

I. An Introduction to Operating Systems What is an Operating System?

What part of your body is most like a computer operating system? If you answered your central nervous system, you’re right! Without your central nervous system, you would be little more than a bunch of body parts—bones, organs, muscles, etc. Your central nervous system ties these parts together, telling them what they need to do and how to work together to keep you alive and functioning.

Similarly, without an operating system a computer would be little more than an expensive box. It couldn’t do any of the things you rely on it to do—open programs, connect to the Internet, send your documents to the printer, etc.

In this lesson, you will learn about the operating system’s role in running your computer.

• Explainthefunctionsofthecomputeroperatingsystem.

• IdentifyanddescribethecomponentsofcommonGUIs.

Objectives:

Vocabulary:

command - instructions that tell a computer what to do.desktop - the background screen on a computer; the main work area.GUI - graphical user interface enabling users to easily interact with their computers.menu - list of commands.multitasking - performing more than one task at a time.window - rectangular area on a computer screen where the action takes place.

based environment. In this type of environment, users had to remember a series of commands and type them after what was called a command prompt to tell the computer what to do.

In the GUI environment, the OS makes it possible for you to make your computer perform a number of different functions just by clicking your mouse. You are probably very familiar with the GUI. It is most likely how you tell your computer what you want it to do. Common features provided by most GUIs include:

• icons; • desktop; • menus; • windows.

Icons. The GUI provides you with pictures called icons that represent different commands, or actions that you want the computer to perform, such as opening a program, or printing a document. A pointing device, such as a mouse, is used to click an icon. Clicking on the icon causes the computer to perform a task. The desktop. The demonstration below shows you a computer desktop. The icons displayed on most desktops represent resources stored on the computer—files, folders, application software, and printers. Another icon commonly found on the desktop is a place to discard items. Users can open programs and files from their desktops. They can also modify their desktops in a number of ways including adding and deleting icons from it. For this reason, desktops of computers running the same operating system may appear different.

Menus. Another common feature of most GUIs is the menu. Menus are another way you can tell your computer what to do. Menus are screens that display a list of commands. Users can tell their computers to perform a number of different actions by selecting a

command from a menu. In the example below, selecting the E-mail icon opens MS Outlook.

Windows. When you use application software, the program opens in a window. Like a window in your home, a window on your computer can open and close. A window is an opening on the computer screen where the action takes place. When you use a program, it opens in a rectangular window. The window may take up the entire screen or just a portion of the screen. The window can be resized. Just as you can have more than one window open at a time in your home, most operating systems in use today allow you to have more than one window open at one time. In fact, it is common for workers to have several open windows running different applications at once. This is called multitasking. Workers can even resize the windows so they can work on more than one at the same time. Dylan, for example, is using a word processing program to draft the monthly sales report. He needs to include figures from a spreadsheet he created, so he opens that file. The spreadsheet opens in a new window. He can switch back and forth between the documents.

Managing application software. The OS provides a way for you to use the programs you want. It serves as an interface, or translator between the commands you give and the computer’s resources—memory, software, or printer. Application software provides instructions to your operating system. These instructions are known as “system calls” because they call on your system to provide services. Let’s take a look at some of the services the OS provides for application software. If you want to open a spreadsheet you saved earlier, you might launch your spreadsheet program and select Open from the File menu. When you do this, your spreadsheet software must request a service from your OS. Your OS generates a list of files from which you can choose the one you want. After you select the file you want, the OS loads the file into the computer’s memory so it is available for you to work with. When you’re done working on the file, you will save it. Your spreadsheet program will also request this service from your OS. Your OS saves your file in an appropriate location so that you’ll be able to use it again.

Coordinating the interaction of hardware and software. The OS manages how application software works with other software programs as well as with the computer’s hardware—the central processing unit (CPU), random access memory (RAM), mouse, keyboard, printer, etc. The OS allocates the computer’s resources to enable it to perform the actions you request, such as entering information into a word processing document, printing a spreadsheet, opening your presentation, querying your database, or saving your DTP layout. This coordination is very important as there is a lot of activity going on behind the scenes when you are working on your computer. As was discussed earlier, OS’s let you multitask. You can have several different programs open at once. It is the job of the OS to allocate RAM to the open applications so they function properly. When you use the mouse or keyboard to communicate with the computer or the application you are using, the OS interprets these actions so that you get the results you want. Clicking on an icon causes an action to take place, such as opening a program or a file. Pressing keys on your keyboard will cause characters to appear in the open window. The OS also provides you with the ability to copy information from one document to another. When you want to print your file, your spreadsheet program will request printing services from the OS. The OS sends your job to the printer. Handling data storage and retrieval. The OS manages the computer’s filing system. It controls how information is stored on the computer and how it is accessed. Your computer has two types of files—program files and data files. Program files are the components that make your application software run. They provide the information to your word processing or spreadsheet program that tells it what to do. Typical programs may contain hundreds or even thousands of files. The image below shows you the folders and files that make up MS Office, a popular application used by many businesses.

Keep in mind that each of the folders also contains a number of files. Generally computers have a number of different applications on them. However, program files aren’t the only files the OS is responsible for. You will recall that there is another type of file stored on computers. Data files are files created by the computer’s users. Your word processing

and spreadsheet documents are data files. Managing the program and data files is a very important service the OS provides. This service is essential to the effective functioning of your application software. It also makes it possible to access the data files you have created. Keeping track of these files is a big job. To perform this task, the OS makes an index of all the files stored on the computer. This index is called a File Allocation Table (FAT). The OS updates the FAT every time a file is created, renamed, moved, or deleted. Additionally, to keep things organized, the OS assigns letters to the computer’s disks or drives to make the storage and retrieval of computer resources easier.

In this lesson, you learned about operating systems. Now it’s your turn to explore your computer to learn a bit more about it.

In this lesson you learned about computer operating systems—the brains of the computer. The OS controls and organizes the computer’s parts—memory, hardware, and software. It performs a number of essential functions, including:

• displayingtheGUI; • managingapplicationsoftware; • coordinatingtheinteractionofhardwareand

software; and • handlingdatastorageandretrieval.

File Management and Security You’ve probably heard your parents talk about utilities and may be wondering what utilities have to do with computing. Like the utilities used in your home—gas, water, electric, or phone—utility programs provide services for your computer. The most common types of services provided by utility programs include file management, security, communication, accessibility, and entertainment.

File Management One of the main purposes of your computer is to store, maintain, and retrieve data. File management utilities help keep your computer and its files in good working order. Some of the most common file management utilities are described below.

Defragmentation. When you are rushing to get ready for school in the morning, you will probably be able to get dressed quicker if your clothes are all together. If some are in the closet, some are under the bed, some are in the living room, and still others are in the laundry room, the process will take longer. Your computer’s operating system (OS) works the same way. When the

items it needs are all stored together, it can find, access, and retrieve them faster and more efficiently.

When you press the save button on your computer, your document is stored in your computer’s memory. If the file is small enough, it will be saved in one location on your computer’s hard drive. However, if the file is large, it will be broken up, or fragmented. Portions of the file will be saved where there is room on the disk. After a period of time, computers become fragmented. When this occurs, the files the computer needs to access are stored in different places on the hard drive and it takes the OS longer to find and retrieve them when you open the file. As a result, computer operations are slowed down.

The following picture provides an example of a fragmented file. The file is represented by the red area. Notice that the file is split into two parts and is saved in different places on the hard drive.

Utilities

If you’re like many students your age, you probably have a cell phone. Most basic cell phones let you make and receive telephone calls and text messages. Most also provide organizational tools such as a calendar, alarm clock, and calculator. Does your cell phone do more? Many cell phones have extra features that enhance cell phone capabilities or even enable it to perform additional functions. Ring tones are an example of an enhancement. They provide more options for how a phone will sound when it rings. The ability to surf the Net or take pictures are examples of added features that increase the jobs a cell phone is able to do.

The utility programs you will learn about in today’s lesson are much like the added cell phone features—not necessary to basic function, but rather an enhancement or addition to the tasks the computer’s operating system is able to perform.

Objectives:

Vocabulary:

defragmentation - process of uniting split-up files so the pieces are saved next to each other on the hard drive.

encryption - scrambling data so that it can be safely transmitted over the Internet.fragmented - broken up computer file saved in multiple parts in different places on the hard drive.multimedia - combination of text, graphics, animation, audio and video in one file.SOHO - group of networked computers in a small office or home office; small office home office.sound card - computer device that records and plays digital audio files.utility - a program that provides a service for a computer.

Fortunately, operating systems come with utility programs that can be run to defragment a computer. When defragmentation utilities are run, they find the pieces of the files that are stored in different locations on the computer’s disk and move data around so that the pieces of files can be stored together.

To improve the performance of their computers and increase their productivity, many workers keep their computers tuned-up by “defragging” them on a regular basis.

VocabularyDefragging is a term that people often use to indicate the running of a defragmentation program.To improve the performance of their computers and increase their productivity, many workers keep their computers tuned-up by “defragging” them on a regular basis.

Windows is the OS used in most businesses. Workers can access the Disk Defragmenter utility through the System Tools menu from the Accessories menu. Once they access the program, they can see how much free space is available. They can also see how much space they will have after running the application.

Most operating systems come with disk defragmenters. However, sophisticated defragmenting programs can be purchased. These applications do a better job of rearranging fragmented data and using vacant disk space.

File compression. This type of utility reduces the size of a file by taking out unnecessary pieces of information. When this data is removed, the files are smaller; they are compressed. Compressed files can be up to 70 percent smaller than the original files. They take up less room on your computer and can be transmitted faster when they are sent as e-mail attachments. Common file compression programs include WinZip and StuffIt.

Backup. You’ve probably heard the expression, “don’t put all your eggs in one basket.” The logic behind this expression is that if you have all of your eggs in one basket and something happens to that basket, you won’t have any eggs left. Well, the same thing is true for the files on your computer. If you keep all your files in one place (your hard disk) and something happens to it (like it crashes), all your files will be lost. For this reason, backing up data is essential.

Most businesses have backup utility programs scheduled to run at regular intervals to protect the organizations’ data. Backup utilities save numerous files to another storage device—an external hard drive, a magnetic tape drive, or compact disks.

Cleaners. As the name implies, cleaning utilities “clean up” your hard drive, providing more space. They get rid of unnecessary files. These programs generally remove temporary files that are installed on your computer when you surf the Web, delete temporary files created by the OS, and empty the Recycling Bin. Disk Clean Up is the name of the cleaner used by the Windows OS. Workers using this OS can access this utility through the System Tools menu, located within the Accessories menu. If your computer is running the Windows OS, you can see how much space you could free up by running this utility.

11

Security If a computer has access to the Internet, security is a serious concern. Although surfing the Web makes many resources readily available, it also exposes computers to security threats. Computers in the workplace and the home use a number of security utilities to keep their computers safe. Some of the more common of these are described below.

Firewall. This utility program provides a barrier between a computer or a computer network and external harmful agents. Firewalls examine data before it is sent from or comes into a computer or a computer network. If the data violates the rules that have been set up, the firewall will not let the data pass.

Antivirus. Viruses are small programs that can spread through a computer or computer network and interfere with its functioning. Antivirus utilities scan the system for viruses and remove any that are found.

Data encryption. Have you ever seen a spy movie in which espionage agents send messages using a secret code that only authorized recipients can decipher? Data encryption utilities work in a similar fashion. Computers today transmit lots of sensitive data such as social security and credit card numbers. Data encryption utilities put this information into a special code when information is transmitted and saved. When the data is opened by authorized users, it is decoded so that it can be read.

File wiping. Did you know that when you delete a file, it is not permanently removed from your computer? When you delete a file, the OS marks the space on your hard drive where the file is stored as available. The file that you deleted can still be accessed until new data is saved in its place on your hard drive. File wiping utilities write over deleted files several times, making sure that they are no longer accessible.

Please refer to the media CD to view Deleting and Wiping Files.

Communication, Accessibility, and EntertainmentCommunication Computers have become a heavily relied-on communication tool. You probably get a lot of information through your computer—from the Internet, blogs, wikis, podcasts, or e-mail. In business, computers are an essential communications device. Communication utilities make sure that data can be successfully sent and received by computers and computer networks. Some of the most widely used utility programs are discussed below. Remote control. If you’re like most people, you probably use remote control devices every day. The most popular of these is the one that is used to operate the television set while sitting on the couch. Similarly, remote control utilities let people operate one computer from another computer. This is useful for IT personnel who may be trying to solve a problem on a worker’s computer. It is also helpful for teachers who are trying to demonstrate a skill to a student. Many workers telecommute, doing their jobs from a location outside of the workplace, such as their homes. In many instances, workers who telecommute use remote control to access their computers in the office. They can log onto the network, run programs, and access files. Network setup. Many small offices and homes have more than one computer. These computers often need to share files, Internet connections, printers, and faxes. Small Office/Home Office (SOHO) network utility programs make it possible for computers near each other to share resources.

Accessibility Accessibility utilities provide tools that make it easier for people to use their computers. On computers running the Windows OS, these tools can be opened from the Accessibility menu on the Accessories menu. Some common accessibility programs are described below. Magnifier. This utility enables the user to enlarge the text on the screen.

Reader. This utility program will read the text that appears on the computer screen. It will also read dialog boxes, menus, buttons, and characters as they are typed. In order to use this utility, computers must have a sound card and speakers. Onscreen keyboard. This utility displays a keyboard on the computer screen. People who have difficulty typing using a regular keyboard can use various pointing devices to select characters from the keyboard displayed on their computer monitors.

Speech recognition. People using this utility speak into a microphone to tell their computers what to do. This utility enables people to open applications, enter text, save files, and print documents using voice commands. In order to use this utility, however, people must first “train” the software to correctly interpret the way they speak—their accent and speech patterns.

Entertainment You may find this difficult to believe, but at one time, computers delivered information primarily in the form of text. Pictures were sometimes used to break up the text and make things a little more interesting. With the advent of faster computing technology, the use of computers for entertainment purposes has increased substantially. Now you can watch videos, tune into your favorite TV shows, listen to music, or hear the latest podcast on your computer. Operating systems generally come with entertainment utilities that make this possible. These utility programs enable users to create and share multimedia files—text, graphics, animation, audio, and video. Two of the most common types of entertainment utilities are discussed below. Audio/video file players. These utility programs let users play multimedia files on their computers. Most operating systems come with this capability. The most commonly used program is MediaPlayer that comes with the Windows OS. The Mac OS uses QuickTime. RealPlayer is another frequently used program that can be downloaded for free from the Internet. Audio recording. Audio recording utilities enable users with sound cards and microphones to save audio files, such as speech, music, laughter, clapping, sound effects—anything that can be heard—to their computers. Some programs, such as Windows Sound Recorder, let you record, mix, edit, and play back your sounds.

In this lesson, you learned about a number of utility programs that provide services for computers. In this exercise, you will learn how running one such program could affect your computer.

In this lesson, you learned that utilities are programs that provide computer services for your computer. The main categories of programs include file management, security, communication, accessibility, and entertainment. This lesson discussed the most common utility programs within each category.
