Although interrupt and exception are two distinct ideas, they are related in the sense that they both force the central processing unit (CPU) to halt the normal flow of execution of instructions and instead begin executing another programme in the kernel space in order to deal with the issue at hand. This is true even though interrupt and exception are distinct ideas. The primary distinction lies in the manner in which they deal with unforeseen occurrences that may take place anywhere in the system, the processor, or even within the programme itself.What is an Interrupt?An interruption is a signal that ...

Linux File Hierarchy Structure is defining the directory structure and the contents of the directory which have been alike to the Unix-like Operating Systems. It is maintained by the Linux Foundation.They are being used for looking at all files and the directories which appear under the root directory. They can be looked upon even if they have been stored on different physical or virtual devices.Even if some of these directories only exist on the particular systems or certain subsystems that can include the OS X, Windows System is installed.ImportanceThe importance of file hierarchy structure is given below −The biggest importance ...

Interrupts are generally called signals which are generated by the software or hardware when a particular event or process requires immediate attention. So, the signal informs the processor about a high priority and urgent information demand causing interruption in the current working process.Thus, whenever an interruption occurs the processor finishes the current instruction execution and starts the execution of the interrupt known as interrupt handling. Moreover, for every interrupt handling to occur there is an Interrupt service routine (ISR) or interrupt handler.Interrupt handling in modern operating systems −In several operating systems such as Linux.mac or windows Interrupt handling is divided ...

A process is defined as a program in execution and an entity that represents the basic unit of work to be implemented in the system.Process switchIt is defined as that the processor switches from one thread/process to another thread or process. It makes the contents of the CPU registers and instruction pointer to be saved.For the new task, the registers and instruction pointer are loaded into the processor then the execution of the new process may start/resume.The old programs will not execute further, but the state of that process is saved in memory because when the kernel decides that it ...

User Interface Design is the design of the interface or system which 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 on the looks or how the app or ...

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 ...
