Low-Level Programming Languages

Low-level coding languages have a lower level of abstraction, and as you might expect, are the opposite of high-level languages. They are closer to binary and farther from human language. Low-level languages are harder to learn and use, but offer more functionality and direct control over the computer. They allow programmers to create far more detailed and efficient computer software.

256INFORMATION CODING SCHEME

WHAT IS MEANT BY ENCODING A DATA? DIFFERENT CODING SCHEMES TO REPRESENT DATA IN THE COMPUTERS.

Computer works only with binary numbers. It stores all types of data in the form binary digits. The data is converted to binary form before it is stored inside the computer the process of converting data into binary form is known encoding. Data can be converted into binary form by using different coding schemes

DIFFERENT TYPES OF CODING SCHEMES:

1. BCD Code

BCD stands for binary coded decimal. It is a 4-bit code. It means that each decimal digit is represented by 4 binary digits. It was used by early computers.

2. EBCDIC Code

EBCDIC stands for extended binary coded decimal interchange code. It is an 8-bit code. It is normally used in mainframe computers. It can represent 256 characters.

3. ASCII

ASCII stands for American standard code for information interchange. It was published in 1968 by ANSI (American National Standard Institute). It is the most widely used coding scheme for personal computers. The 7-bit code can represent 128 characters. It is not enough to represent some graphical characters displayed on computer screens. An 8-bit code can represent 256 characters. The extended 128 unique codes represent graphic symbols.

4. Unicode

Unicode is a 16-bit code. It can represent 65536 characters. It has started to replace ASCII code. It can represent the characters of all languages in the world.

  

Computers are in every aspect of our lives. Hardworking software developers, data scientists, and software engineers have the power to shape how these computers that surround us work. 

Knowing how to program will potentially allow you to build anything you could imagine on a computer and some things you can’t. If that sounds appealing then let’s cover some of the base types of computer programming languages.
