1) The document discusses different types of computer software including application software, system software, operating systems, and utilities. 2) It provides details on important figures in computer history like Ada Lovelace, considered the first computer programmer. 3) The main types of operating systems are described - stand-alone, network, and embedded operating systems. Common examples for each type are listed.

1. COMPUTER SOFTWARE
CSS-NCII TRAINING

2. Definition:
Software,orprogram,enablesacomputertoperformspecific tasks,asopposedtothe
physical components ofthesystem(hardware).

3. Who Was Ada Lovelace?
The daughter of famed poet Lord
Byron, Augusta Ada Byron, Countess
of Lovelace—better known as "Ada
Lovelace"—was born in London on
December 10, 1815. Ada showed her
gift for mathematics at an early age.
She translated an article on an
invention by Charles Babbage
(known as the Father of the
Computer), and added her own
comments. Because she introduced
many computer concepts, Ada is
considered the first computer
programmer. Ada died on November
27, 1852.

4. Two main types:
•Application Software –consists of programs designed to make users more productive and/or
assist them with personal tasks.
•SystemSoftware –consists of programs that control ormaintain the operations of the
computer and its devices.

26.  System software actually controls the hardware so that
application software can perform any action or task.
 The System Software consist of the Operating System and all the
utilities that enable the computer to function.

27. a set of programs containing instructions that
coordinate all the activities among computer
hardware resources. Also called platform

28. provides user interface
manages programs
manages memory
schedules jobs
configure devices
establishes an Internet connection
monitors performance
providing file management and other utilities
controlling a network
administering security

31. 1)Stand-alone OS – a complete operating system that works on a desktop
computer, notebook computer, or mobile computing device. Ex. DOS, Windows XP,
Mac OS X, UNIX and Linux

34. 2. Network OS – an operating system that is designed specifically to support
a network and typically resides in a server. Ex. Netware, Windows Server 2003,
UNIX, Linux and Solaris.

38. 3. Embedded OS – an operating system found on most PDAs and
small devices. Ex. Windows CE, Windows Mobile, Palm OS, Embedded
Linux and Symbian OS.

39.  Browsing
 Messaging
 Multimedia
 Communication Protocol
 Mobile telephony
 Data Synchronization
 Security
 Most secured and customized and open source
operating system
 Support different version of mobile 2G, 2,5G,
3G
 Integrated multimode Mobile telephony
 Application environment
 Multi-tasking
 Robustness
 Flexible
 Is small, fast ,and efficient
 Easy to use
 Allows simple and fast desktop
synchronization
 Embraces diversity
 Palm OS is discontinued mobile
operating system initially developed by
Palm Inc., for personal digital assistants
(PDAs) in 1996. It was designed for ease
of use with a touchscreen-based
graphical user interface

41. • A program that performs maintenance-type tasks, usually related to
managing a computer, its devices, or its programs. Also called utility,
could be built-in programs in the Operating System or stand-alone
utilities.
• Helps maintain or configure a computer. Many of these are installed at
the same time as the OS but they can also be added afterwards

42. • File manager, Image Viewer, Personal Firewall,
Uninstaller, Disk Scanner, Disk Defragmenter, Diagnostic
Utility, Backup Utility, and Screensaver.

43. Antivirus Programs, Spyware Removers, Internet Filters (Anti-Spam
programs, Web Filters, Pop-up Blockers) File Compression, File
Conversion, CD/DVD Burning, and PC Maintenance.
