If you are on Windows, your computer might not recognize the device automatically. You may need to install the (specific to your phone brand like Samsung, Pixel, OnePlus). You can find a list of these drivers on the Android developer website.
While ADB works within the Android operating system, works outside of it. Fastboot is a protocol designed for flashing partitions while the device is in bootloader mode.
Crucially, Fastboot uses with no flow control beyond the protocol itself. This is why interrupting a fastboot flash can hard-brick a device—the protocol assumes a complete, uninterrupted data stream.
Before we discuss how they work, we must define what they are. sdk platform tools work
Disconnect the USB cable, run adb kill-server , and reconnect the cable. Look for the prompt on the device screen to explicitly allow debugging. "Device Not Found" (ADB)
from any terminal window without navigating to the specific folder." For a Status Update or Confirmation Setup Complete:

Ensure you have the Google USB Driver installed.
adb push uploads files to the device.
fastboot flash : Overwrites a specific storage block (such as boot , system , recovery , or vendor ) with a raw binary image. While ADB works within the Android operating system,
The client is the command-line executable ( adb ) invoked by the user via a terminal or an IDE like Android Studio. When you type a command like adb devices or adb install app.apk , you are interacting directly with the client. The client’s sole responsibility is to parse the command and send it to the ADB server. 2. The Server
A hidden mechanic most users miss: adb exec-out bypasses terminal escape character processing. When you run adb shell cat file.jpg , the terminal might corrupt binary data because it interprets 0x0D as a carriage return. exec-out uses a raw pipe, allowing you to pipe binary images directly into a file on your PC. This works because the protocol supports a "raw" data mode flag.
So, At their core, they are a thin, efficient, bidirectional protocol bridge that translates your keyboard input into Linux kernel calls on a remote device.
