Sample text

There is a total of eight bits for every character in your computer, and eight bits is known as a byte. Therefore, every character of storage takes eight bits to represent (eight on and off switches), and therefore, a character is a byte. The reason it takes eight switches is that if there were fewer, there wouldn’t be enough combinations of on and off states to represent all the characters possible (uppercase, lowercase, digits, and special characters such as %, ^, and *). Tip Years ago, somebody wrote the various combinations of eight 1s and 0s from 00000000 to 11111111 and assigned a unique character to each one.

The early computers’ memories held only data and not programs. The concept of programming those early computers was vastly different CHAPTER 3 PROGRAMMING LANGUAGES: THE EARLY YEARS 47 because the programs were hard-wired into the machine. The programs were physically wired by experts to generate and process the data. The first computer programmers had never heard of using a keyboard, editor, and compiler; the first programmers were hardware experts, not software experts. Programming these computers was very difficult.

Over the years since the first computer language was invented, hundreds of programming languages have been written, but there are a handful that have dominated the rest. The following is a list of several programming languages that gained more than obscure notoriety through the years: Machine Language * Assembler * Algol PL/I * PROLOG * LISP COBOL * Forth RPG * CHAPTER 2 ANATOMY OF A PROGRAM Java * Pascal * HTML * SNOBOL Ada * C* C++ * XML * FORTRAN * SmallTalk BASIC * Visual Basic * 29 APL * The languages marked with an asterisk (*) achieved dominance either through sheer numbers of users or within a specific area of expertise.
