The First Computer Programmer

Ada Lovelace was the daughter of the poet Lord Byron. She was taught by Mary Somerville, a wellknown researcher and scientific author, who introduced her to Charles Babbage in June 1833. Babbage was an English mathematician, who first had the idea for a programmable computer.

In 1842 and 1843, Ada translated the work of an Italian mathematician, Luigi Menabrea, on Babbage’s Analytical Engine. Though mechanical, this machine was an important step in the history of computers; it was the design of a mechanical general-purpose computer. Babbage worked on it for many years until his death in 1871. However, because of financial, political, and legal issues, the engine was never built. The design of the machine was very modern; it anticipated the first completed general-purpose computers by about 100 years.

When Ada translated the article, she added a set of notes which specified in complete detail a method for calculating certain numbers with the Analytical Engine, which have since been recognized by historians as the world’s first computer program. She also saw possibilities in it that Babbage hadn’t: she realised that the machine could compose pieces of music. The computer programming language ‘Ada’, used in some aviation and military programs, is named after her.

Text for the questions 19 to 21

There were very few computers in the 1950s, and those in existence were treated as objects of wonder with almost mythical powers. They were nothing like the computers of today. For one thing they were huge, with the refrigerator-sized one being relatively small for the time. They were also delicate, and consumed a lot of electricity, wasting much of it as heat.

Nowadays, however, a computer is just another item stocked in supermarkets alongside toothpaste and dog food. And as computers have become cheaper and smaller, they have been incorporated into a kaleidoscopic range of devices that bear no resemblance to what was once thought of as a computer. Powerful computers now sit at the heart of objects as diverse as mobile phones and games consoles, cars and vacuum cleaners. The cost of computer power continues to decrease, making it possible to incorporate computer technologies into almost any object, no matter how small, cheap or disposable. And these smart devices are ‘talking’ to one another, not just within a single room or building but across the world via the internet, using the World Wide Web . Thus even as the computer vanishes from sight, it becomes vastly more powerful and ever-present – to use a term you’ll become very familiar with, it is now ubiquitous.
