Raspberry Pi with Bluetooth is available in two variants:
The integrated Bluetooth module is Bluetooth Classic and Low Energy (Bluetooth 4.1, BLE).

The USB is a universal external interface for all sorts of peripheral devices that are to be operated on Raspberry Pi. Typically keyboard, mouse, pen drives, wireless adapter and the like.
USB 2.0 has a transfer speed of up to 480MBit/s. That’s the equivalent of 60MB/s. Which is more of a theoretical value.
As a rule, you can barely reach more than 30MB/ s on a USB 2.0 port. And that only when transferring large files or a long-lasting data stream. But not when transferring a lot of small files, as is typical.

That’s the easiest. At the same time, the digital audio signal is also transmitted and output if the screen has speakers.
When choosing the HDMI cable, you should pay attention to high-quality HDMI cable, because cheap are of questionable quality and often not all pins in the plug are occupied. As a result, running the Raspberry Pi on an HDMI screen becomes a gamble. However, this is not the raspberry pi hdmi port problem, but the manufacturer of the HDMI cable, which has interpreted the HDMI standard in his favor.
Whoever buys cheap here, buys twice

Choosing the power supply will determine if experimenting and working with Raspberry Pi will be a nuisance or if you can have many successful experiences. In particular, anyone who has an application for which Raspberry Pi should run continuously should carefully select the power supply.
Because not every power supply is equally suitable for Raspberry Pi. This is not due to Raspberry Pi, but to the power supplies that are either poor in quality or unsuitable for powering Raspberry Pi.

The power supply of Raspberry Pi is one of the underrated sources of error. Minicomputers, like Raspberry Pi, require a stable voltage AND power supply.
With a bad power supply and unfavorable operating conditions, strange effects in combination with an unstable system behavior occur.
The effect referred to in the German-language Raspberry Pi Forum as “Mysterious” usually manifests itself in the discontinuation of LAN and WiFi connections and other malfunctions of devices connected to the USB.
For example, external WiFi adapters, USB sticks, and hard disks.
