Now, let's learn how to connect the various components to the CPU. | |
Show all the components on a table | Place all the components on the table, as shown. |
Show all the cables on a table | Place all the cables on the table, as shown. |
Rotate the monitor and show back side. | First, let's connect the monitor to the CPU. |
Show the power cable >> Show the blue part being connected to the CPU
(zoomed in animation to show the part clearly) |
Connect the power cable to the monitor, as shown. |
Show the power plug being connected to a power supply socket. | Now, connect the other end to a power supply socket. |
Show the CPU power cable >> connect it to the CPU | This is the power cable of the CPU.
|
Show the power plug being connected to a power supply socket. | Then, connect it to a power supply socket. |
Show the keyboard cable >> Show the cable head part being connected to the CPU
(zoomed in animation to show the part clearly) |
Next, connect the keyboard cable to the CPU, as shown.
|
Show the mouse cable >> Show the cable head part being connected to the CPU
(zoomed in animation to show the part clearly) |
You can connect the mouse to the port which is “green” in colour. |
Show the mouse cable >> Show the cable head part being connected to the CPU
