![Page 2: Software. Application Software performs useful work on general-purpose tasks such as word processing and data analysis. The user interacts with the application.](https://reader035.fdocuments.us/reader035/viewer/2022062320/56649d5d5503460f94a3ca84/html5/thumbnails/2.jpg)
Software• Application Software
performs useful work on general-purpose tasks such as word processing and data analysis. The user interacts with the application software.
• System Software Enables the application software to interact with the computer hardware. The operating system is the most important system software.

System software
• System software deals with the complexities of the computer hardware.
• System software consists of four kinds of programs:– Operating systems– Utilities– Device drivers– Language translators.
![Page 4: Software. Application Software performs useful work on general-purpose tasks such as word processing and data analysis. The user interacts with the application.](https://reader035.fdocuments.us/reader035/viewer/2022062320/56649d5d5503460f94a3ca84/html5/thumbnails/4.jpg)
• Operating systems operate the computer by coordinating computer resources, provides interface, runs applications
• Utilities (service programs) manage computer resources to help identify problems, locate lost files, and back up data
• Device drivers are designed to allow particular input or output devices to communicate with the computer
• Language translators convert programming instructions into computer actions

Operating systems manage . . .• Resources: coordinate all computer resources,
including mouse, keyboard, printer, monitor, storage devices, and memory.
• User interface: most operating systems provide a windows-like graphical user interface (GUI) in which graphical objects (icons) are used to represent commonly used features.
• Applications: load and run applications such as word processors and spreadsheets. Most support multi-tasking, or the ability to run more than one application at a time.

Microsoft Windows
• Designed to run with Intel-compatible microprocessors
• Variety of versions: 95, 98, 2000, ME, XP• Named from rectangular window-like boxes
used to display information and run programs
• Multiple windows can be open at the same time for easy multi-tasking

Windows interface is called the desktop.

Utilities• Troubleshooting programs recognize and correct
problems, ideally before they become serious.
• Antivirus programs guard against damaging virus programs that can invade the computer.
• Uninstall programs allow user to safely remove unneeded programs.
• Backup programs make copies of files in case originals are lost or damaged.
• File compression programs reduce the size of files so they require less storage space and can be sent more efficiently over the Internet

Windows Utilities (System Tools)
• Backup allows user to create backup for hard disk
• Disk Cleanup helps identify and eliminate nonessential files to free up disk space and improve performance.
• Disk Defragmenter locates and eliminates unnecessary fragments, rearranges files and unused disk space to optimize performance

Utility Suites
• Anti-virus programs
• Clean-up suites
• Crash-protection programs
• Web-service monitors
• Best known are McAfee and Norton.
