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.

Difference between context switching and schedulling?
Scheduling has to do with how the job scheduler decides which task will have the CPU and for how long. This is the technique of multi-tasking; the appearance of running multiple processes at the same time (when they really aren't). Context switching occurs when a process needs to do something in a privileged way, such as requiring communication with another hardware device. When the process is typically running it is in user mode, which is a non-privileged mode of operation. It has to context switch into kernel (privileged) mode to do things, then switch back. The main difference between the two is that context switches happen in a non-predictive manner in the same program/process, and job scheduling is predictable (to a point). Then again, they serve different needs of the Operating System, as well.
What is the difference between process switch and mode switch?
Process switch is switch the process state between the status like read, blocked ,suspend. Mode switch is the switch the process privilege between the mode like use mode, kernel mode. Generally a mode switch is considered less expensive compared to a process switch.
What is new application enabled by Asynchronous Transfer Mode?
ATM is a fusion between fast switching and synchronous multiplexing technique.
What is critical conduction mode?
Critical conduction mode is a mode of operation in power electronics where the current flowing through a switching device drops to zero before the next switching event occurs. This mode is efficient for reducing switching losses and maximizing converter efficiency, commonly used in applications like power supplies and motor control.
What is the difference between Store Display Mode and regular home mode on televisions?
nothing they are both the same
What are the different modes of vi editor?
Command mode, and input mode. You switch between them using the ESC key.The two modes of 'vi' are input mode, and command mode. In input mode all you can do is insert text, and in command mode you can make editing changes to existing text (by issuing commands).Switching between the modes is accomplished by pressing the ESC (escape) key.
Which LAN switching mode has the highest latency?
store-and-forward
What is difference between minimum mode and maximum mode of 8251?
The 8251 is a USART (Universal Synchronous Asynchronous Receiver Transmitter). It does not have a minimum and maximum mode.
What is the use of the shortcut command F2 when editing the text on Excel?
F2 begins the process of editing, by switching you into edit mode for the active cell. Once you have started editing, pressing F2 does not do anything.F2 begins the process of editing, by switching you into edit mode for the active cell.

What is the difference between graphic mode and text mode?
In text mode your options will be limited to fonts, sizes, and colors; in graphic mode you should have more Paint-like options.
Difference between safe mode and safe with commandprompt?
Both "safe mode" and "safe mode with command prompt" runs with essential drivers that is necessary for the computer to function. Difference is, Safe mode runs with "Explorer.exe" shell and "safe mode with Cmd prompt" runs with "cmd.exe".
