Reading is an action performed by computers, to acquire data from a source and place it into their volatile memory for processing. Computers may read information from a variety of sources, such as magnetic storage, the Internet, or audio and video input ports. Reading is one of the core functions of a Turing machine.
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
For conventional binary computers, machine code is the binary representation of a computer program which is actually read and interpreted by the computer. A program in machine code consists of a sequence of machine instructions (possibly interspersed with data). [1] Each machine code instruction causes the CPU to perform a specific task.
Code Reading (ISBN 0-201-79940-5) is a 2003 software development book written by Diomidis Spinellis. The book is directed to programmers who want to improve their code reading abilities. It discusses specific techniques for reading code written by others and outlines common programming concepts.
A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. Such program is often the first written by a student of a new programming language, [ 1 ] but such a program can also be used as a sanity check to ensure that the computer software intended to compile or run source ...
Code has been included in the syllabi of post-secondary education technical courses, such as "Fundamentals of Modern Software" where it was called "a little dated, but it is a really clear and incredibly accessible presentation of how computers get from electrical currents flowing down wires to programs you can actually use" [8] and other ...

A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using a compiler written for the language.
