LAN port

Let's talk about the LAN port. The LAN port or the ethernet port is used for wired internet connection which uses a LAN(Local area network) cable. But some computers do not have these LAN ports because it is a very bulky port which makes the laptop thicker. So these ports are not in-build in many computers. So if you don't have a LAN port on your machine, you can use a USB Network Adapter.

Difference between VGA and HDMI

VGA is an analog interface while HDMI is a digital interface. VGA is a video interface which means we can only use it for video transmission while HDMI includes both the audio and video. Devices with the VGA interface have lower video resolution compared to modern HDMI devices. Also, VGA ports are very bulky.

Many computers don't have this type of port, it is mainly used in Apple computers. It features a new, smaller connector shape that's reversible so it's easier to plug in. USB-C cables can carry significantly more power, so they can be used to charge larger devices like laptops. They also offer up to double the transfer speed of USB 3 at 10 Gbps.
