2007 Silverado LTZ 4 door, Drivers side windows don't work but passenger side windows work fine from the master switch even after replacement. Odd that I have 4.5 volts at the plug to the window motor when the switch is activated even with the new switch and 12 volts to the switch and the window lock-out does not stop the other switches from.

Context Switching involves storing the context or state of a process so that it can be reloaded when required and execution can be resumed from the same point as earlier. This is a feature of a multitasking operating system and allows a single CPU to be shared by multiple processes.
A diagram that demonstrates context switching is as follows −
In the above diagram, initially Process 1 is running. Process 1 is switched out and Process 2 is switched in because of an interrupt or a system call. Context switching involves saving the state of Process 1 into PCB1 and loading the state of process 2 from PCB2. After some time again a context switch occurs and Process 2 is switched out and Process 1 is switched in again. This involves saving the state of Process 2 into PCB2 and loading the state of process 1 from PCB1.
Context Switching Triggers
There are three major triggers for context switching. These are given as follows −
- Multitasking: In a multitasking environment, a process is switched out of the CPU so another process can be run. The state of the old process is saved and the state of the new process is loaded. On a pre-emptive system, processes may be switched out by the scheduler.
- Interrupt Handling: The hardware switches a part of the context when an interrupt occurs. This happens automatically. Only some of the context is changed to minimize the time required to handle the interrupt.
- User and Kernel Mode Switching: A context switch may take place when a transition between the user mode and kernel mode is required in the operating system.
Context Switching Steps
The steps involved in context switching are as follows −
- Save the context of the process that is currently running on the CPU. Update the process control block and other important fields.
- Move the process control block of the above process into the relevant queue such as the ready queue, I/O queue etc.
- Select a new process for execution.
- Update the process control block of the selected process. This includes updating the process state to running.
- Update the memory management data structures as required.
- Restore the context of the process that was previously running when it is loaded again on the processor. This is done by loading the previous values of the process control block and registers.
Context Switching Cost
Context Switching leads to an overhead cost because of TLB flushes, sharing the cache between multiple tasks, running the task scheduler etc. Context switching between two threads of the same process is faster than between two different processes as threads have the same virtual memory maps. Because of this TLB flushing is not required.
Windows 10 provides an amazing feature with which you can easily manage and organise your work. This feature is Multiple Desktops, also termed as Virtual Desktop. Ams ringtone maker 2 0 0. Yes! You can have more than one desktop at a time on a single machine, and of course, switch between them.
Imagine having 10 to 15 applications open on your desktop. Tuneskit screen recorder 1 0 16. What a mess! To manage this stuff, you can go for multiple desktops and move a few of the applications to another desktop.
If you are working on multiple projects simultaneously, then you can create different desktops for different projects. Such as one for a game related project, one for an under-development website, one for communicating with your teammates and another, maybe for some amusement like songs, games or a movie.
After creating a number of desktops, you need to know how to switch between them. Windows 10 is very fast and switching between the desktops is even faster. This article is going to tell you three very simple methods to quickly switch to a different desktop in Windows 10.
Steps to switch between the Desktops in Windows 10
Method 1: Using Task View Button
Task View button is present on the taskbar in Windows 10. This button looks like:
Sometimes, the Task View button is hidden by default. You can make it visible in two steps:
- Right-click on Taskbar.
- Select the Show Task View button.
Step 1: Click on the Task View button present on the taskbar.
As soon as you click, a new screen will appear.
Smooze 1 5 4 – rediscover your mouse cursor. This screen contains four things:
- Taskbar at the bottom: This taskbar belongs to the desktop which is currently open.
- Desktop ribbon: Above the taskbar, appears a ribbon which holds all the desktops which you have created. They are given names like Desktop 1, Desktop 2 and so on.
- New Desktop button: Look at the right-most corner on the Desktop ribbon, you will find a New Desktop button represented by a Plus sign. By clicking on this button, you can create a new desktop.
- Active applications on the current desktop: The major part of this screen is covered by the snaps of applications which are active on the current desktop. If you hover the mouse on different desktops present on the ribbon, the applications of the respective desktop will appear in this area.
Step 2: Just click on the desktop which you want to open from the Desktop ribbon.
Method 2: Ctrl + Windows + Arrow Key(Left/Right)
This is a keyboard shortcut to switch between the desktops in Windows 10.
Step 1: Press the Ctrl key and Windows key simultaneously.
Step 2: Without leaving the above two keys, press the left/right arrow key once.
This will take you to the neighbouring desktop. Pressing the arrow key again will take you to the next desktop. In this way, you can go through all the desktops one by one using the keyboard shortcut.
This will take you to the neighbouring desktop. Pressing the arrow key again will take you to the next desktop. In this way, you can go through all the desktops one by one using the keyboard shortcut.
Method 3: Four – finger Swipe
If you have a touch-screen, then this is the best way to switch between the desktops in Windows 10.
Swipe with four fingers in either direction and the neighbouring desktop will slide into the screen. If you want to go back to the previous desktop, swipe again with four fingers in the opposite direction.
