1 Lecture 4 : Windows 7 By MSc. Manar Joundy Hazar 2017
This presentation introduces you to the Windows 7 operating system. Understanding your operating system streamlines your workload and saves you time.

2 Windows 7 Windows 7: is an operating system released by Microsoft on Oct. 22,2009. Windows 7 has graphical user interface (GUI) that allows you to visually interact with your computer’s functions in a logical, fun, and easy way

3 Types of Windows 7 The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system. 32 bit system has a limit of 4GB RAM to process data where as the 64 bit operating system has 2^64 bits of space to address and supports 16 hexabytes of RAM to process data.

4 Minimum System Requirements for Windows 7
Part Minimum Requirement Processor (CPU) 1 GHz or faster CPU Memory (RAM) 1 GB RAM (32-bit) or 2 GB RAM (64-bit) Hard drive free space 16 GB available disk space (32-bit) or 20 GB (64-bit) Disc drive DVD drive Graphics memory 128 MB or more

5 Starting Windows 7 When you turn the computer ON “cold booting”, the computer will upload the operating system. Booting: the time from turn ON until the user get the access to there computer .

6 Desktop

7 Welcome Screen

8 The Desktop The Desktop is the main Windows 7 screen. It is the work area where dialog boxes, windows, icons, and menus appear.

9 Desktop Icons The Desktop is where you’ll find icons (small pictures) for many of your most frequently used programs. You’ll most likely see icons for Computer, Documents, Recycle Bin, and Internet Explorer.

10 Windows 7 Desktop Operating system Desktop Taskbar Window Icon Desktop
Icons Let’s begin our study of Windows 7 with some definitions. These definitions apply to all computer systems ,so they are worthwhile to understand. The operating system is a software application that controls the activities of the computer. Behind the scenes ,it accepts input from devices, such as the keyboard and mouse, and directs output to the monitor and speakers. It keeps track of your files and folders on storage devices, such as disk drives and flash drives. It provides security for your computer system. It communicates with the other software applications you have on your computer and enables them to work together. The desktop is the screen that displays once you have turned on the computer and responded to prompts for your user name and password. This is your workspace. It is where you manage tasks on the computer. Your software opens on the desktop. You manipulate your files and folders on the desktop. The taskbar provides you with access to the software applications, enables you to move between the applications, and gives you access to system resources. It is a horizontal bar that appears at the bottom of the screen. A window is a space on the desktop representing a program, system resource, or data. Multiple windows can be open at one time, working independently as well as together. For instance, if you write a report on the latest sales for your company, you will open a spreadsheet and copy the net profit directly from the spreadsheet into the report document. Windows can be moved around the desktop, minimized to take up less space, and maximized to fill the desktop. Icons are small pictures that represent programs, files, folders, or other things on the desktop. Objects with the same characteristics, like file folders, have the same icon. Software icons are unique so that you can quickly find the software application. Don’t worry if the desktop you see in your office or at school is different than the one you have at home. Computers have unique configurations of installed programs and files. Windows 7 enables you to create a desktop environment with which you are comfortable by adding or removing icons that fit your needs. Start button Taskbar Copyright © 2011 Pearson Education, Inc.

11 Desktop

12 Desktop Components Icons – graphic image (pictures ) that represents an object available to your computer. Desktop picture or background-Displays the colors and graphics of your desktop; you can change the desktop background to look the way you want it such as using a picture. Also called wallpaper. Desktop-your workplace on the screen. Start Button-provides access to Windows 7 programs, documents, and information on the Internet. Generally located in the lower left corner of the desktop.

13 Desktop Components Program buttons-launches Internet Explorer, Windows Media Player, Windows Explorer and the program buttons that you have chosen to pin to the taskbar. Taskbar-contains the Start button and buttons that give you quick access to common tools and the programs currently running. Generally located along the bottom of the desktop.

14 Desktop Components Notification area-shows the notification icons, the current date and time and lets you set the clock. Also known as the system tray and generally located in the lower right corner of the desktop. Recycle Bin icon-contains files and folders that you delete. The deleted files are not gone until you empty the Recycle bin. My Computer: My Computer allows the user to explore the contents of their computer drives as well as manage their computer files

15 The Taskbar Word Excel Program icons
The taskbar enables you to move between open windows and provides access to the resources of your computer. Just as you can have many files and papers covering your desk, in Windows 7, you can have many applications open on your computer desktop. Using the taskbar, you activate a window that is covered by other windows by clicking the program icon. If you have used Windows in the past, it is important to note that, by default, only one program icon appears for each application that is running, not an icon for each window. For instance, if you open a cover letter and a résumé on the desktop, only one program icon─for Microsoft Word─will appear on the taskbar. If you wish to change this so that there is an application icon for each open window, right-click an open area of the taskbar, select Properties, click Never Combine on the Taskbar buttons list box, and then click OK. You may also select to combine the application icons when the taskbar is full. The windows shown here are for Microsoft Excel and Microsoft Word. On the taskbar, the program icons are different. To bring the Word document to the front, simply click the Word program icon. Program icons

16 The Taskbar The taskbar enables you to move between open windows and provides access to the resources of your computer. Using the taskbar, you activate a window that is covered by other windows by clicking the program icon.

17 The Notification Area Pop-up window Open Action Center link
The Notification area alerts you to important information about activities going on behind the scenes in your computer. A red circle with an X on the notification icon indicates that a message is available. Click the notification icon and a pop-up window displays the information. The notification area provides information on the detection of new devices on your computer, the availability of software updates, or recommended maintenance and security tasks. The notification can be opened for more information by clicking on the Open Action Center link. The pop-up window, shown here, is a result of clicking the Action Center icon on the taskbar. The Action Center is discussed in a later slide of this presentation. Action Center icon Notification area Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.
