Same. RS-232C: DB-25 is a more common one, there is also a range of coverting cables (eg DB9 to DB25).
Correct. manufacturers need to be licensed by HDMI Licensing Administrator, Inc. (HDMI LA) in order to implement HDMI in any product or component.

dev >> raspberry pi 400+
The Raspberry Pi 400 was released in November 2020. A modern example of a keyboard computer, it features 4 GB of LPDDR4 RAM on a custom board derived from the existing Raspberry Pi 4 combined with a keyboard in a single case. The case was derived from that of the Raspberry Pi Keyboard. A robust cooling solution (i.e. a broad metal plate) and an upgraded switched-mode power supply allow the Raspberry Pi 400's Broadcom BCM2711C0 processor to be clocked at 1.8 GHz, which is 20% faster than the Raspberry Pi 4 upon which it is based.

A keyboard computer is a computer which contains all of the regular components of a personal computer, except for a screen, in the same housing as the keyboard. The power supply is typically external and connects to the computer via an adapter cable. The motherboard is specially designed to fit inside, and the device is larger than most standard keyboards. Additional peripheral components such as a monitor are connected to the computer via external ports. Usually a minimum of storage devices, if any, is built in.

"I'm not writing it to remember it later, I'm writing to remember it now"
- fieldnotesbrand motto
"Genius is 1% talent and 99% percent hard work.”
- Albert Einstein
When you’re first learning a new concept, you’re taking in further information that has to go through the process of memorization.
The human brain, however, is inefficient at remembering things.
Within 24 hours of leaving class, your brain will have forgotten more than half of what it remembered at the end of the class.
This phenomenon is described by the Ebbinghaus forgetting curve, which perfectly illustrates the need for note-taking.
Some different methods of note taking worth looking at the see what suits you best:

Outline Note-Taking Method
Cornell Note-Taking Method
Boxing Note-Taking Method
Charting Note-Taking Method
Mapping Note-Taking Method
Sentence Note-Taking Method
Q/E/C Note-Taking Method

Whether or not you’re picky, know that tools for the hands are tools for the brain. Handwritten notes are a powerful tool for encrypting embodied cognition and in turn supporting the brain’s capacity for retrieval of information. And secondly, when you take notes by hand, your hands create a robust external memory storage: your notebook.
Taking notes by hand is a win-win, and belongs in every student’s cognitive tool kit. Learning how to take notes by hand effectively, and how to ingrain note-taking as a key learning and study tool, can begin as early as grades 3 or 4, but it’s never too late to begin.
We live in a digital age where daily functioning involves digital communication. Automaticity in keyboarding is an important skill too, and the tools and applications for digital communication will continue to evolve and have their place. But keyboarding does not provide the tactile feedback to the brain that contact between pencil or pen and paper does — the key to creating the neurocircuitry in the hand-brain complex.

We live in a digital age where daily functioning involves digital communication. Automaticity in keyboarding is an important skill too, and the tools and applications for digital communication will continue to evolve and have their place. But keyboarding does not provide the tactile feedback to the brain that contact between pencil or pen and paper does — the key to creating the neurocircuitry in the hand-brain complex.
While your laptop might seem faster and more efficient, there are good reasons for having a paper-bound notebook and pen — any kind you prefer — at the ready.
Researchers have found that note-taking associated with keyboarding involves taking notes verbatim in a way that does not involve processing information, and so have called this “non-generative” note-taking. By contrast, taking notes by hand involves cognitive engagement in summarising, paraphrasing, organising, concept and vocabulary mapping — in short, manipulating and transforming information that leads to deeper understanding.
Note-taking becomes note-making: an active involvement in making sense and meaning for later reflection, study or sharing of notes to compare understanding with lab partners or classmates. This becomes a potent study strategy, as one’s own processing can be further consolidated through talk
