Different Types of Operating Systems
An operating system performs all the basic tasks such as managing files, processes and memory. Operating systems act as the manager of all resources that is resource management. This means that an operating system acts as an interface between the user and the machine. There are different types of operating systems in the market which include:
Batch operating system
This type of operating system does not interact with the user directly. It has an operator who takes similar jobs which possess the same requirement and then group them into batches. It’s the responsibility of the operator to sort the jobs in a similar manner according to their needs.
Due to the challenge of knowing the time that is required by any job to complete the processes. The processors of batch system know exactly the duration in which it will take to complete the task. It also has the advantage of sharing batch systems by multiple users. They also have a very small idle time even for batch processes. It is also very easy to manage large amounts of work repeatedly.
The operators of the computer should be well known with the batch systems. They are very hard to debug and sometimes costly. Other types of jobs will have to wait for a certain period of time in case any of the jobs fail.
Time-Sharing Operating systems
Each of the tasks is given time to execute so that all the tasks are able to work smoothly. This is because each of the user gets a time as a single system. The systems are also known as multitasking systems in that the tasks can be single user or different users and the time that each task is given is known as quantum. After each of the time interval then the operating system switches over to the next task. Some of the examples of time-sharing operating systems include Multics, Unix etc.
Each of the task gets an equal opportunity and there is a vert little chance of duplication of the software. The idle time of the CPU can also be reduced by a great magnitude.
The shortcoming with the system is that it is unreliable. There is also data communication problems and one need to take care of security and integrity of the user programs and the data.
Distributed operating system
This type of operating system is a recent advancement in the world of computer technology and are being widely accepted all over the world. Various autonomous computer systems work together using a shared communication network. The independent systems possess their very own memory unit and CPU. They are often referred to as loosely coupled systems or distributed systems. The processor of these systems differs in size and function. The greatest benefit with working with this type of system is that it is always possible for one user to access the files or software which are not actually present in a system but on some other system connected in the network. Some of the examples include LOCUS.
One of the greatest advantages with distributed processing is that failure of one of the systems will not affect the network communication as the other systems will function perfectly well. Computation is also very fast and durable since the resources are being shared. There is also delay in data processing and electronic mail increases the speed of data exchange. This is ideal for sites and applications that can’t afford to go down for while being maintained such as casual dating sites like FuckFinder.App and dating apps like Tinder among other various user based applications.
The entire communication will failure in case there is failure of the main network. The language used are not yet well defined and these types of systems are readily not available.
Network operating systems
These types of systems run on a server and provide the capability to manage data, groups, security, users, applications and other network functions over a small private network. Another important aspect of network operating system is that all users are well aware of the underlying configuration of the users within the network and their individual connections. This is the reason why these computers are known as tightly computed systems.
Network operating systems hold the advantage of having highly stable centralized servers. Their security servers are also handled through servers the server access is possible remotely from different locations and systems. The new network technologies as well as hardware upgrade can easily be integrated.
The servers are very costly and users have to depend on a central location during most of their operations. The maintenance and updates are also done regularly.
Real-time operating systems
These types of operating systems serve as the real time systems in that the time that is required to process and respond to time is very small. The time interval is called responsive time. They are often used when time requirements are strict like missile systems, robot and air traffic control systems.
