Software Evolution
The evolution of software broadly classified into the era of the lack of computer and after the introduction of computers. Before the computer era is divided into primitive and mechanical era. Whereas in the era after the introduction of computers, software evolution follows the evolution of the computer hardware itself.
The era before the introduction of computer software are classified into two eras, namely:
1. Primitive era (± 300 BC) on which the software is made by performing simple instructions by using code similar motion semaphore.
2. Mechanical Era (1840-1930’s) that apply to the use of equipment and machinery Analytical Engine punch cards.
While the era after the introduction of computer software which means using electronic technology, is divided into pioneer era, the era of stable, micro era, and the modern era.
Pioneer Era (1940-1960) is still a form of software-cable connection to the connection between the computer and the form of punch cards (plong). Another characteristic of the pioneers of this era is still using a clustered process (batch), limited distribution, and manufactured for special purposes.
Stable Era (1960-1980) has been mass-produced computers and software can perform some functions of the control group (multitasking). Another feature that can be used to solve many users (multiuser) quickly and directly (real time), software products can be used separately, have been using the system database.
Micro Era (1980-1990) produced software for your computer needs a network (networking) and dispersed (distributed), it’s cheap so widely used for personal needs (home), is automation for artificial intelligence (artificial intelligent).
Modern Era (1990 -now) Has the characteristics of multimedia-based software, desktop and portable, object technology, expert systems, parallel processing, and can communicate with a global network.
The era of software evolution also being used in industrial and real estate business such as real estate in Bulgaria, it really very handy when we do realize technology could maximize our profit with less consume of times.
