they're not totally indistinguishable, they overlap as one is needed for the other. context switching is the process of storing and restoring the state of a process. when a interrupt handler interrupts a program, the context switch is enacted. the current programs status is saved and then once the program interrupt is finished, then program interupted is restored. the program interrupting is the computers way of responding to outside stimuli. in simple terms it saves the programs status, deals with what ever the interrupt is, then restores the programs status (what ever said program happens to be).

Difference between process switching and context switching?
It has been suggested that process switching and thread switching be merged into this article or section. (Discuss) Proposed since April 2012.
What is the difference between context switch and process switch?
when ever an interrupt occurs, it saves the context of the program being executed & sets the PC to the starting address of the interrupt handling program. now after servicing the interrupt if the same process is resumed which was being interrupted then we will say a context switch has occurred.But imagine after servicing the interrupt if a new process is to be executed then some more work is required, that is it has to save some more information from the PCB to keep reference to resume its execution and we say process switch has occurred..!!
What is the difference between context switching and mode switching?
Context means ,in terms of computers, the status of various general purpose registers having some process specific data values and even some other structures dependent on computer hardware,i.e. PCB etc. Now what context switch means ,""switching from one status of registers set to another status of registers set."" This context may be of a process or thread etc. Now when we are talking about any type of context switching,,it means we are requesting the KERNEL to save the current context anywhere,and fetch the next context for us.. It requires a mode switch between user mode to kernel mode, so that required switching may be performed in right order.... Isn't it simple ,,or what.
Explain what context switching mode is and can a PC run in context switchin mode?
explain what context switching mode is. and can a PC run in context switching mode
How is the term 'switching' used in context?
Switching is typically used in the context of switching phone lines or switching digital networks. It could also be used in the context of switching companies that provide services such as water or electric.
What are interrupters?
An interrupt is a hardware-generated change of flow within the system. An interrupt handler deals with the cause of the interrupt. Control is then returned to the interrupted context An interrupt is a hardware-generated change of flow within the system. An interrupt handler deals with the cause of the interrupt. Control is then returned to the interrupted context
What the difference between style shifting and code switching?
Style shifting and code switching both involve changing the way you communicate based on the social context or situation. Style shifting refers to adjusting your language or communication style, while code switching specifically involves alternating between different languages or dialects within a conversation.
How do you say interrupt in German?
Depending on context, interrupt can be translated as:unterbrechenstörenabbrechenhineinredenins Wort fallen
What is key difference between a trap and interrupt?
An interrupt is generally initiated by an I/O device, and causes the CPU to stop what it's doing, save its context, jump to the appropriate interrupt service routine, complete it, restore the context, and continue execution. For example, a serial device may assert the interrupt line and then place an interrupt vector number on the data bus. The CPU uses this to get the serial device interrupt service routine, which it then executes as above.A trap is usually initiated by the CPU hardware. When ever the trap condition occurs (on arithmetic overflow, for example), the CPU stops what it's doing, saves the context, jumps to the appropriate trap routine, completes it, restores the context, and continues execution. For example, if overflow traps are enabled, adding two very large integers would cause the overflow bit to be set AND the overflow trap service routine to be initiated.
Why used interrupts?
An interrupt is a signal from hardware (h/w interrupt) or software (s/w interrupt) to indicate the occurence of an event. It indicates the need of a change in execution. Interrupt handling or servicing of the interrupts depends upon the design of the operating system. A routine which will be called for servicing the interrupt is known as interrupt service routine or ISR and the request for the ISR through an interrupt is known as interrupt request or IRQ. Interrupt is a mechanism used for implementing the multitasking concept. It will use the concept of context switching, for servicing the request.
What is the use of interrupt vector?
An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table. Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is generated, the processor saves its execution state via a context switch, and begins execution of the interrupt handler at the interrupt vector.
What is the difference between an antonym context clue and synonym context clue?
They're opposites
