HEWLETT PACKARD LAPTOPS
William (Bill) Hewlett and David (Dave) Packard both graduated from Stanford University in 1934. The company originated in a garage in nearby Palo Alto during a fellowship they had with a past professor at Stanford during the Great Depression.
The partnership was formalized on January 1, 1939 with an investment of $538. Hewlett and Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett. Packard won the coin toss but named their electronics manufacturing enterprise the "Hewlett-Packard Company".
HP incorporated on August 8, 1947, and went public on November 6, 1957.
Headquartered in Palo Alto, California, United States, it has a global presence in the fields of computing, printing, and digital imaging, and also provides software and services. The company, which once catered primarily to engineering and medical markets—a line of business it spun off as Agilent Technologies in 1999—now markets to households and small business products such as printers, cameras and ink cartridges found in grocery and department stores.
HP posted US $91.7 billion in annual revenue in 2006 compared to US$91.4 billion for IBM, making it the world's largest technology vendor in terms of sales. In 2007 the revenue was $104 billion, making HP the first IT company to report revenues >$100 billion.
According to Gartner, HP is the largest worldwide seller of personal computers, surpassing rival Dell, market research firms Gartner and IDC reported in October 2006; the gap between HP and Dell widened substantially at the end of 2006, with HP taking a near 3.5% market share lead.

The Germans also developed a series of teleprinter encryption systems, quite different from Enigma. The Lorenz SZ 40/42 machine was used for high-level Army communications, termed "Tunny" by the British. The first intercepts of Lorenz messages began in 1941. As part of an attack on Tunny, Professor Max Newman and his colleagues helped specify the Colossus. The Mk I Colossus was built between March and December 1943 by Tommy Flowers and his colleagues at the Post Office Research Station at Dollis Hill in London and then shipped to Bletchley Park.
The Colossus was used to break German ciphers during WWII
Colossus was the first totally electronic computing device. The Colossus used a large number of valves (vacuum tubes). It had paper-tape input and was capable of being configured to perform a variety of boolean logical operations on its data, but it was not Turing-complete. Nine Mk II Colossi were built (The Mk I was converted to a Mk II making ten machines in total). Details of their existence, design, and use were kept secret well into the 1970s. Winston Churchill personally issued an order for their destruction into pieces no larger than a man's hand. Due to this secrecy the Colossi were not included in many histories of computing. A reconstructed copy of one of the Colossus machines is now on display at Bletchley Park.
