But what about? Indeed, “the arrow on the monitor does not move” means that the computer is not working! 🙂 But you and I will be interested in exactly that “iron box that stands under the table”, and the name is its system unit! 🙂

The computer’s power supply is responsible for the uninterrupted power supply of the entire system unit. The failure of this node completely de-energizes the computer and it stops turning on. Or it starts to “glitch” in the most unpredictable way, which is also not kosher 🙂 Continue reading

First of all, let’s divide network cards into two large groups:

External network cards
Built-in or integrated (onboard)
Let’s start with the external ones. From the name itself, it follows that network cards of this type are installed in the computer system unit additionally (as a separate expansion card) or as another external device. Continue reading
