System software includes operating systems, device drivers, and utilities. It controls hardware resources, manages storage and processing, and enables the use of application software. Application software helps users perform specific tasks like word processing, games, communication, and business functions. Examples include Microsoft Office, web browsers, media players, and enterprise resource planning systems. Both system and application software work together to run computers and software programs.

6. SystemSoftware
– System software is computer software designed to operate
the computer hardware, to provide basic functionality, and to
provide a platform for running application software.
– System software includes device drivers, operating systems,
servers, utilities, and window systems.
– System software is responsible for managing a variety of
independent hardware components, so that they can work
together harmoniously.

8. Types
• Operating Systems (OS):
– Examples: Windows, macOS, Linux, Unix, Android, iOS
– Operating systems manage hardware resources, provide essential
services (such as file management, memory management, and process
management), and act as an interface between applications and
hardware.
• Device Drivers:
– Examples: Printer drivers, graphics card drivers, network drivers
– Device drivers enable communication between the operating system
and hardware devices, allowing them to function properly.
• Utilities:
– Examples: Disk defragmenters, antivirus software, backup tools
– Utilities perform various system management tasks such as disk
maintenance, security, and data backup.

9. Scenario-based Examples
• Operating System (OS):
Scenario: Sarah boots up her computer. The operating system, such
as Windows 10, loads first. It manages hardware resources, provides
a graphical user interface (GUI), and enables Sarah to interact with
her computer. She navigates through files, launches applications,
and performs various tasks seamlessly due to the OS's management
of resources.
• Device Drivers:
Scenario: John installs a new graphics card on his computer. Upon
installation, the operating system detects the new hardware but
requires specific device drivers to properly communicate with the
graphics card. John installs the graphics card drivers provided by the
manufacturer, allowing the operating system to utilize the graphics
card's capabilities effectively.

11. Types
• Productivity Software:
– Examples: Microsoft Office (Word, Excel, PowerPoint), Google Workspace (Docs, Sheets, Slides), Adobe
Creative Suite (Photoshop, Illustrator, Premiere)
– Productivity software helps users create, edit, and manage documents, spreadsheets, presentations, and
multimedia content.
• Communication Software:
– Examples: Email clients (Outlook, Thunderbird), instant messaging apps (WhatsApp, Slack), video
conferencing tools (Zoom, Skype)
– Communication software facilitates communication and collaboration between users through various
channels such as email, instant messaging, and video conferencing.
• Entertainment Software:
– Examples: Video games, multimedia players (VLC, iTunes), streaming services (Netflix, Spotify)
– Entertainment software provides users with recreational activities such as gaming, watching videos, listening
to music, and accessing online content.
• Business Software:
– Examples: Enterprise resource planning (ERP) systems, customer relationship management (CRM) software,
accounting software (QuickBooks, Xero)
– Business software helps organizations streamline their operations, manage resources, and support business
processes.
• Educational Software:
– Examples: Learning management systems (LMS), educational games, interactive tutorials
– Educational software assists in teaching and learning activities, providing educational content, assessments,
and instructional resources.
