How will use Mouse Pointer by Keyboard?

If you want to use the mouse pointer by Keyboard then follow this instruction…..
Start-->Settings-->Control Panel-->Accessibility Options-->Mouse Tab and then check the Use Mouse Keys Box and “OK” at last “Apply.”

Now, you will see a logo, which like Mouse in Taskbar. Please active the logo to press Num Lock key. You can choose any key to use, go to the setting option and choose any key.

Basically, you will get default keys like …… 2,3,6,8 which stay below of Num Lock key. Now, you can use the mouse pointer Left-Right and Up-Down with 2,4,6,8. It is note that “5” will work like “Enter” key. To get help, look these pictures....

Networking of Computer: Cable Punching


Now I am sharing the networking process. If we can know how to built or connect a computer with another computer then, we will do many work together and we know that sharing works would be acceptable and we can do every work perfectly.

I narrate
Network Cable Setup : We can be connected a computer with another computer by Twisted Pair cable. Manually Twisted Pair Cable has partly eight cables into cover of the cable and every cable is various colors. We need RJ45 connector to connect cable. At first connect RJ45 with Twisted Pair Cable by Punching. It is called Cable Punching.

Twisted Pair Cable’s cable
  1. Orange White  =================
  2. Orange             =================
  3. Blue White       =================
  4. Blue                  =================
  5. Green White   =================
  6. Green               =================
  7. Brown White   ================= 
  8. Brown              =================              

Now, we connect with two PC that means we do not use HUB. So the cable punching’s crossing is in below-----

      1st Side                                           2nd Side
1. Orange White                             1. Green White  
2. Orange                                        2. Blue
3. Green White                              3. Orange White
4. Green                                          4. Green
5. Blue White                                 5. Blue White
6. Blue                                            6. Orange
7. Brown White                             7. Brown White
8. Brown                                        8. Brown


Now, I am narrating how to connect with more computers for networking by Twisted Pair Cable. We should to use a HUB or a Switch. Obviously it is easy and cable color would be punched at same colored cable. In below the connection process has been written ……
