The numbers might be reconstituted into a version of the original.These numbers can be stored, retrieved, processed, transmitted.Something (sound, pictures, text, instructions….) is converted into numbers by some mechanism.Here I will just mention it briefly.ĭigital representation means that everything is represented by numbers only. I have written a post on encoding which you can read if more information is needed.

But before that, lets take a detour and learn a little bit information about encoding and storage in digital world.
PROTOCOL STX ETX CODE
Ok, we talked a little bit about ASCII and later I will show you some sample code regarding ASCII usage. Bits, Bytes and Representation of Information Specifically, the messages that application programs must send to the network interface. However today, we will ignore the means of transport and examine the contents of the transmissions. Most commonly, it is the means by which data-packets are transferred between computers. Network Protocol has many levels of meaning. This communication follows certain protocols. You type a web address in the browser address-bar, Press enter and a whole bunch of TCP/HTTP communication happens behind the scene and a web page is shown in the browser. You are meeting with the queen, someone from the palace communicate the protocol and it is followed. You will find a common use of ASCII in command/query scenarios, where you can send ASCII commands to industrial devices and these devices perform actions or send status information back. And computers must read this stuff, and they do that with bar code readers that translate those funny lines into ASCII characters that those products above have to move around. There are labels on products, markings on boxes, etchings on car tires, and much, much more. Why is there so much ASCII, you might ask? It’s how humans communicate.
PROTOCOL STX ETX SERIES
An Ink pressure is encoded as a long series of ASCII codes such as: 2.3145 Every XML element starts and ends with the angled bracket ASCII codes. XML, the eXtensible Markup Language, is a way of transferring computer data from one place to another and is built solely with ASCII codes. As computers were developed in the 1960s, ASCII became THE standard for sending information. They reorganized telegraphic codes, sorted them, and worked with the American Standards Association (ASA) to form ASCII (American Standard Code for Information Interchange). Not many people know that ASCII was birthed in the 1960s when Bell Labs had a need for a standard way to send text.

It’s the only data format that can be universally decoded by any computer on the planet. You may not believe this but ASCII is really powerful. It transmits only ASCII characters and uses ASCII control codes. So, I just want to say this upfront if you see me talking about ASCII as protocol as well.ĪSCII is The simplest communications protocol for text. That’s true, but in a lot of documents on the internet you will find that ASCII is refereed to as protocol as well. It’s not a protocol protocols can be built on top of ASCII. In this post, we will discuss ASCII, a little bit of history and learn that why it is so hard not to fell in love with ASCII. This story was published in media all over the world and with that ASCII was in the news again. Reddit users and social media posters on Twitter noticed that the red-and-white pattern on the parachute looked deliberate, and arrived at the result by using the red to represent the figure one, and the white to represent zero.
