4.1 Types of software and interrupts
4.1.2 Operating systems
To enable computer systems to function correctly and allow users to communicate with computer systems, software known as an
operating system needs to be installed. An operating system provides both the environment in which applications can be run and a
useable interface between humans and computer.
An operating system also disguises the complexity of computer software and hardware. Common examples of operating systems include:
Microsoft Windows, Apple Mac OS, Google Android and Apple IOS (the latter two being used primarily on tablets and smartphones).
Most computers store the operating system on a hard disk drive (HDD) or solid state drive (SSD) since they tend to be very large programs.
Mobile phones and tablets store the operating system on a solid state device since they are too small to accommodate an HDD.
Figure 4.7 summarises some of the functions in a typical operating system.
