- Network OS
- Mobile OS
Functions of Operating System
Some ordinary working framework capacities might incorporate overseeing memory, documents, processes, I/O framework and gadgets, security, and so on
The following are the fundamental elements of Operating System:
In a working framework programming plays out every one of the capacity:
- Process the board: Process the executives assists OS with making and erase processes. It additionally gives components to synchronization and correspondence among processes.
- Memory the executives: Memory the board module plays out the assignment of designation and de-portion of memory space to programs needing this assets.
- Document the board: It deals with all the record related exercises like association stockpiling, recovery, naming, sharing, and security of records.
- Gadget Management: Device the board keeps tracks, everything being equal. This module likewise liable for this assignment is known as the I/O regulator. It likewise plays out the undertaking of allotment and de-distribution of the gadgets.
- I/O System Management: One of the fundamental objects of any OS is to conceal the eccentricities of that equipment gadgets from the client.
- Optional Storage Management: Systems have a few degrees of capacity which incorporates essential capacity, auxiliary capacity, and reserve stockpiling. Guidelines and information should be put away in essential capacity or store so a running system can reference it.
- Security: Security module safeguards the information and data of a PC framework against malware danger and approved admittance.
- Order translation: This module is deciphering orders given by the and acting framework assets to deal with that orders.
- Organizing: A disseminated framework is a gathering of processors which don’t share memory, equipment gadgets, or a clock. The processors speak with each other through the organization.
- Work bookkeeping: Keeping track of time and asset utilized by different work and clients.
- Correspondence the board: Coordination and task of compilers, mediators, and one more programming asset of the different clients of the PC frameworks.

Disadvantages of Operating System
- In the event that any issue happens in OS, you might lose every one of the substance which have been put away in your framework
- Working framework’s product is very costly for little size association which includes trouble them. Model Windows
- It is never completely secure as a danger can happen whenever
What is Kernel in Operating System?
The part is the focal part of a PC working frameworks. The main occupation performed by the bit is to the deal with the correspondence between the product and the equipment. A Kernel is at the core of a PC. It makes the correspondence between the equipment and programming conceivable. While the Kernel is the deepest piece of a working framework, a shell is the peripheral one.
Features of Kernel
Low-level booking of cycles
Between process correspondence
Types of Kernel
There are many kinds of pieces that exists, however among them, the two most well known portions are:
A solid part is a solitary code or square of the program. It offers every one of the necessary types of assistance presented by the working framework. It is a shortsighted plan which makes a particular correspondence layer between the equipment and programming.
Microkernel deals with all framework assets. In this sort of portion, administrations are carried out in various location space. The client administrations are put away in client address space, and part benefits are put away under bit address space. Along these lines, it assists with diminishing the size of both the bit and working framework.
Difference between Firmware and Operating System
Below are the Key Differences between Firmware and Operating System:
|Characterize Firmware: Firmware is one sort of programming that is implanted on a chip in the gadget which controls that particular gadget.||Characterize Operating System: OS gives usefulness well beyond that which is given by the firmware.|
|Firmware is programs that been encoded by the manufacture of the IC or something and cannot be changed.||OS is a program that can be installed by the user and can be changed.|
|It is stored on non-volatile memory.||OS is stored on the hard drive.|

Operating System Functions
All Operating system functions are shared below –
- DEVICE MANAGEMENT
Working System oversees gadget correspondence by means of their particular drivers.
It does the accompanying exercises for gadget the executives −
- Keeps tracks, all things considered. I/O regulator is liable for this assignment
- Concludes which cycle gets the gadget when and for how long.
- Dispenses the gadget in a productive manner.
- De-dispenses gadgets.
- FILE MANAGEMENT
The working framework distributes and de-allots assets. It directs which cycle gets the document and for what span. Additionally, it monitors data, area, utilizes, status and so on
