Software
Network Operating System
manage and control network resources and facilitate communication between computers in a network. They provide services such as file and print sharing, security, and network administration.
Example
Microsoft Windows Server
Linux distributions configured as servers (e.g., Ubuntu Server, CentOS)
Novell NetWare (an older example)
Application Software
designed to perform specific tasks or functions for end-users. It includes a wide range of programs catering to various needs, such as word processing, spreadsheet management, multimedia editing, etc.
Example
Microsoft Office Suite (Word, Excel, PowerPoint)
Adobe Creative Suite (Photoshop, Illustrator, Premiere Pro)
Web Browsers (Google Chrome, Mozilla Firefox)
Enterprise Application
software systems designed to address the needs of organizations and businesses. They often integrate various functions and departments within an organization and facilitate information flow across the enterprise.
Example
Enterprise Resource Planning (ERP) systems (SAP, Oracle ERP Cloud, Microsoft Dynamics)
Customer Relationship Management (CRM) systems (Salesforce, HubSpot)
Supply Chain Management (SCM) systems (JDA Software, Manhattan Associates)
Horizontal System

Example
Electronic Medical Records (EMR) systems for healthcare industry
Property Management Software for real estate industry
Point-of-Sale (POS) systems for retail industry
Legacy System
Legacy systems refer to outdated or obsolete software and hardware that are still in use due to the high cost or complexity of replacement. These systems may lack support or updates from vendors and can pose challenges in terms of integration and maintenance.
Example
Mainframe computers running COBOL-based applications
Older versions of proprietary software no longer supported by vendors
Custom-built applications developed using outdated technologies
System Software
Example
Operating Systems: Windows, macOS, Linux, Unix
Device Drivers: Printer drivers, graphics card drivers
Utility Programs: Disk defragmenters, antivirus software
System software is responsible for providing a platform for running application software and managing computer hardware resources. It includes operating systems, device drivers, utilities, and other software tools.
