explain what context switching mode is. and can a PC run in context switching mode
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.
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.
store-and-forward
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.
The LAN switching mode that begins switching after reading only the first 64 bytes of the frame is known as "cut-through switching." In this mode, the switch starts forwarding the frame as soon as it reads the destination MAC address, allowing for lower latency compared to store-and-forward switching, which waits for the entire frame to be received and checked for errors before forwarding. This method is beneficial in environments where speed is critical.

Infrastructure mode requires an access point. Ad-hoc does not.
Cut-through mode.
This means that the 4wd system is in the process of switching to (or from) 4wd mode.
In any environment, in order to execute a privileged instruction you have have to switch from user mode to kernel mode, hence a context 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.
you cant they turn off after hours of discontinued use or switching the program to sleep mode.
