Answer:
ans1- The Analytical Engine was to be a general-purpose, fully program-controlled, automatic mechanical digital computer. It would be able to perform any calculation set before it. There is no evidence that anyone before Babbage had ever conceived of such a device, let alone attempted to build one.
ans2- System software is software designed to provide a platform for other software.Many operating systems bundle application software. Such software is not considered system software when it can be uninstalled usually without affecting the functioning of other software.
ans3- The fundamental sequence of steps that a CPU performs. Also known as the "fetch-execute cycle," it is the process whereby a single instruction is executed. The first half of the cycle transfers the instruction from RAM to the instruction register (fetch) and decodes it. The second half executes the instruction.
ans5- The Recycle Bin acts a 'holding bay' for deleted items, such as files and folders (and even shortcuts!). When you delete a file or folder, it is not deleted from your computer permanently. Instead, Windows 7 places the deleted items into the Recycle Bin.
ans6- Windows 7 is an operating system released by Microsoft on October 22, 2009. It follows the previous (sixth) version of Windows, called Windows Vista. Like previous versions of Windows, Windows 7 has a graphical user interface (GUI) that allows you to interact with items on the screen using a keyboard and mouse.
ans7- Create a shortcut from a folder
1. Open the Windows File Explorer by pressing the Windows key and E at the same time.
2. Browse to the folder that contains the program for which you'd like to create a shortcut.
3. Right-click on the program and select Create Shortcut from the drop-down menu that appears.
ans8- Use the shift key to select a group of consecutive files:
1. Select the first file you want.
2. Press and hold the shift key.
3. Select the last file you want.
4. Release shift key and all selected files remain highlighted.
5. Use the mouse to press and hold anywhere on the highlighted group.
6. Drag and drop the group into a folder.
ans9- System software is meant to administer the system resources. It also serves as a kind of platform for running the application software. On the other hand, application software is meant to enable the user to carry out some specific set of tasks or functions. System software is meant to manage the system resources.
