The hybrid system adopts a single strictly defined structure and they combine different structures resulting in the hybrid system. The hybrid system is generally used in mobile and laptops.Hybrid system is a type of system which is used for increasing the performance, security and other user services and it is ... Read More

The user and operating system are connected with each other with the help of interface, so interface is used to connect the user and OS.In computers there are different types of interface that can be used for connection with computers to users and their connection is responsible for data transfer.Also, ...

The major differences between block-oriented and character oriented devices are as follows −Block Oriented DeviceBlock devices are storage devices that can provide data operations in fixed-size blocks for both reading and writing.Hard drives, floppy disks, and optical drives, such as DVD-ROMs and CD-ROMs, are some examples of such machines.Usually, blocking ...

An operating system is an interface between the user and the machine which controls and coordinates the use of the hardware among the various application programs for the various users.The four types of operating system structures are −MS-DOS structureThis is the simplest of all the other structures. In this structure, ... Read More

Operating systems work as an interface between the user and the computer hardware. It is a software which performs the basic tasks like input, output, disk management, controlling peripherals etc.Windows, Linux etc. are some examples of operating systems.Tasks of Operating SystemsThese are some important tasks of the OS by which ...

Peterson's solution ensures mutual exclusion. It is implemented in user mode and no hardware support is required therefore it can be implemented on any platform. Now Peterson’s solution uses two variables: interest and Turn variable.Now we will first see Peterson solution algorithm and then see how any two processes P ... Read More

Whenever a process is accessing the shared variable then that process is said to be in the critical section. If no two processes are in the same critical section at same time then this technique is called mutual exclusion.ExampleMutual exclusion problem with assigned priority is shown below −Let us see ...

A semaphore is a shared variable which is used to implement mutual exclusion between system processes. It is mainly helpful to solve critical section problems and is a technique to achieve process synchronization.There are two types of semaphores which are as follows −Binary semaphore − Can take only two values, ...

The essential properties of the different types of operating systems are as follows −Batch Operating systemJobs with similar needs are batched together and run through the computer as a group by an operator or automatic job sequencer. Performance is increased by attempting to keep CPU and I/O devices busy at ... Read More
