Let us understand the concepts of user interface and user interaction designs respectively.User Interface DesignThe design of the user interface is directly accessible by the user and they interact with in order to do a task. It establishes the way with which the user will interact with the product.Its main aim is to enhance the appearance of the product, the quality of technology used, and the usability of the product. It refers to the software or the hardware of the system which the user can see and also the various ways or commands to control or use the product.It focuses ... Read More

Generally, an interface acts as a shared boundary across two or more separate components of a computer system that are used to exchange information. Those exchanges can be between software, computer hardware, peripheral devices, etc.Now let us discuss the good interface and bad interface.A good interface design is user friendly. This is because it is easy to navigate, easy to use, easy to understand, interactive and effective. A good design should always be clear and user centric.Features −ClearConsistentSimpleUser controlledForgivingProvide feedbackSome of the Examples of Good Interface design −Elastic Scrolling on iOSDropbox’s responsive colour system.Pinterest’s waterfall effectA bad interface design is ...

Application ProgramApplication programs are programs that are developed for end-users. These programs provide an application to the end-user and hence used by them. They are loaded into the system according to the needs of the user.The examples include web browsers, Email, gaming, etc.System ProgramSystem Programs are the programs that are used to develop and program the operating system. They act as middleware between the user interface and system calls.The end-user while interacting with the OS uses application programs that in turn give rise to various system calls and the tasks are executed. Also, an OS provides services to run the ... Read More

Generally shell is a software program that acts as a mediator between the kernel and the user. It reads the commands and interrupts by sending requests to execute a program. So, the shell is known as a command interpreter.It contains almost 100 system calls. It tells the kernel to carry out various tasks for the program. These tasks are as follows −Opening a file.Writing a file.Obtaining information about a file.Executing programs.Terminating a process.Changing the priority of processes.Getting the time and date.A shell is a layer of user programs that executes our commands. It is like an interface to the operating ... Read More

The different type of process executing in the operating system and a process which connects the different types of tasks to the operating system is called Inter process communication.The inter process communication is used between the computer and different types of tasks are interconnected with the operating system.A process that is executing concurrently in the operating system can be either an independent process or cooperative process.Independent processIt is a process which is independent and it is not affected by other processes executing in the system. Any process that does not share data with any other process is independent.Cooperative processIt is ... Read More

First, let us understand operating system debugging.Operating system debuggingDebugging is the process of binding and fixing the error, in an operating system both hardware and software problems can be fixed with the help of debugging.When there is a problem in the performance of the operating system the user needs to debug the operating system, so that the performance problem will be solved and remove all the error and fix the error for running smoothly.Debugging is the process where the user needs to analyse the failure and after seeing the failures they can check the performance and find out the error ...

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 very efficient in the operating system.Types of Hybrid SystemsThere are three types of hybrid systems used in the OS. They are mostly used in every device. These types are as follows −Mac OSThe mac OS generally uses a hybrid structure and it is a layered system, the Mac OS consists ... 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, in computers there are different interfaces. These interfaces are not necessarily used but can be used in computers whenever it is needed. So, different types of tasks can be performed by the help of different interfaces.Command line interfaceThe command-line interface is an interface whenever the user needs to have different ...

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 devices read or write the entire block at a time. Most of the file schemes are also based on block computers.The benefit of block devices is that it provides fewer pins to access data; however, it includes the implementation of a buffering mechanism to speed up access during access to ...

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, both the system processes as well as the user processes are allowed to access the system hardware.Features of DOS −DOS is a 16-bit operating system.Here the input is typed with basic system commands.It allows 2 GB maximum.It is a free OS.DOS is usually called as single operating system.It does not ...
