Fifth Generation (Present - Future) Artificial Intelligence
System Software performs tasks that are common to computer systems
in general. The system software provides the
infrastructure
needed to run application software, allowing it to interface
with the hardware of the computer system.
, Application Software consists of the programs that perform tasks specific to the
machine's general purpose. A computer used to maintain a
store's inventory needs different software than a machine used
by a mechanical engineer. Spreadsheet, database, desktop
publishing, accounting, and program development software
are all examples of application software.
Software Hierarchy
Application Software Types Spreadsheets, web browser, accounting, etc.
System Software Types Microsoft Windows, Linux, Mac OS X, DOS, etc.
Operating System (OS) is software that manages computer hardware and software
resources and provides common services for computer
programs
- performs basic tasks such as: file management, memory
management, process management, handling input and
output, and controlling peripheral devices such as drives and
printers
Three of the most common operating Microsoft Windows, MacOs, and Linux
systems
Utility Software provides additional functionality to the operating system
examples: software to compress or decompress data, play
multimedia presentations, and handle network
communications
Kernel is the internal part of an operating system (contains the basic
functions of the OS) It's the underlying ode that runs the OS,
allowing it to perform required tasks such as running
applications and managing peripherals like memory
and graphics
Device Drivers (middleware) facilitate the communication of hardware and software
- A print driver needs to be installed if a user wants to send a
document to the printer. A Bluetooth headphone driver is
necessary if a user wants to listen to music on Bluetooth
headphones. Some device drivers are installed automatically,
while others would need to be downloaded and installed
from the manufacturers' sites.
