Study Notes
Software Distribution Models
-
Proprietary Software: Software owned by a company, requires a license for use. Examples: Adobe Photoshop, Microsoft Windows
- Advantages: Stable, tested, easy support access
- Disadvantages: Must purchase, limited sharing, no access to source code, reliance on developer for fixes
-
Open Source Software: Source code available for modification and distribution, typically free of charge. Examples: OpenOffice, Linux, VLC Media Player
- Advantages: Free or low cost, collaborative bug fixing, potential for feature additions
- Disadvantages: Less user-friendly, limited support, potential for vulnerabilities
- Shareware: Trial version of proprietary software, often with limited features or time usage. Examples: Various software programs
- Freeware: Free software without limitations. Often distributed under a GPL (General Public License) allowing modification and redistribution.
Software Categories
- System Software: Programs that manage and control computer operations, essential for computer function. Examples: Operating System, Utility programs
- Application Software: Programs designed for specific user tasks. Examples: Word processors, graphic design software
Software Piracy
- Illegal copying, distribution, or use of software (intellectual property).
- Detrimental to software developers, hindering innovation and financial incentives.
Software Installation and Uninstallation
- Installation: Adding a new program to the computer. Typically involves running an installer program, accepting terms and conditions (EULA), and potentially requiring an activation key.
- Uninstallation: Removing software from the computer. Requires using the uninstall feature to ensure complete removal of all files associated with the program.
Software Updating
- Updating software addresses bugs, adds new features, and enhances security.
- Patch: A small update to fix bugs.
- Service Pack: A package containing multiple patches released over a period of time.
Utility Programs
- Programs for managing, maintaining, and securing the computer.
- Archiving: Compressing and storing outdated files for retrieval.
- Backup: Creating duplicate copies of files for data recovery.
- Disk Cleanup: Removes unnecessary files like temporary internet downloads, deleted files from the recycle bin, unused Windows components, and uninstalled programs.
- Compression (WinZip, WinRAR): Reducing file size through compression, requiring decompression for use.
- Disk Defragmentation (HDD Only): Reorganizes file clusters on a hard drive to improve file access speed.
Device Drivers
- Programs that allow the operating system to communicate with hardware devices.
- Automatic Driver Installation (Plug and Play): Devices are automatically detected and configured, requiring no manual intervention.
- Manual Driver Installation: Drivers must be manually installed if not included in the operating system, often downloaded from the internet.
Types of Operating Systems
- Embedded Operating System: Operating systems stored on internal memory chips, designed for specific tasks in devices such as ATMs, POS systems, e-readers, traffic lights, and TVs.
- Network Operating System: Operating systems designed for managing and sharing resources, communication, security, and multiple users in a network environment. Examples: Unix, Linux, Microsoft Server
- Stand-Alone Operating System: Operating systems that run on PCs, laptops, and notebooks, managing hardware and software.
Operating System Functions
- Graphical User Interface (GUI): Provides visual controls for user interaction with the computer and software.
- Input/Output Control (Device Management): Manages input and output devices, communicating between hardware and software (assisted by device drivers).
- Disk Management (Storage/File System Management): Organizes files on storage devices and manages access to them.
- Memory Management (RAM): Manages RAM usage and allocates virtual memory when needed.
- Process and Task Management (CPU): Manages CPU resources, scheduling programs and tasks.
File Storage and Information Management
- FAT (File Allocation Table): An index that records the location of files on a storage medium.
- Indexing of Files: A database that stores file and folder names, size, date modified, and text content (meta-data) for file searching.
