Operating systems are software that are responsible for managing the functions of a computer. There are so many different types of operating systems. The average computer user is not familiar with many of them, but it is good to know the names of a few.
Roles of the OS
The OS performs a certain set functions that are needed for the unit to work. It manages the RAM (Random Access Memory), the processor, the efficiency of applications, input and output operations and file management and other functions.
Some Types of OS
Some types of operating systems and their uses are:
Batch Processing OS
There is limited interaction between the processor and the user with this type. While work is being done there is sometimes no direct input. This type of system is generally used when there are massive amounts of data being processed. While this is occuring the user does not have to do anything.
Embedded Operating System
These are used on small devices such as smartphones and PDAs.
Multi-tasking and Single-Tasking OS
As the name implies, these systems can do a number of things at the same time.
Real Time OS
This type is used where a lot of processing power is needed. It processes each bit of data inputted simultaneously because of its power. It is used for industrial operations where fast processing is a requirement. They must also as the name suggests, operate in real time.
The operating system is therefore an integral part of the computing system. Without it, the computer is just a bunch of components that do nothing. The OS is actually the software which is used to operate the PC. When there are problems with the OS, a number things can happen to your computer. These include system crashes, problems working properly with peripheral devices, and in some cases, the unit becomes exposed to external security threats. Of all the operating systems in existence the ones most people would be familiar with are the multi-user and the multi-tasking types.
