HEWLETT PACKARD DESKTOP COMPUTERS
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.

ADVANCED ANALOG COMPUTERS
Cambridge differential analyzer, 1938
Before World War II, mechanical and electrical analog computers were considered the "state of the art", and many thought they were the future of computing. Analog computers use continuously varying amounts of physical quantities, such as voltages or currents, or the rotational speed of shafts, to represent the quantities being processed. An ingenious example of such a machine was the water integrator built in 1928; an electrical example is the Mallock machine built in 1941. Unlike modern digital computers, analog computers are not very flexible, and need to be reconfigured (i.e., reprogrammed) manually to switch them from working on one problem to another. Analog computers had an advantage over early digital computers in that they could be used to solve complex problems while the earliest attempts at digital computers were quite limited. But as digital computers have become faster and used larger memory (e.g., RAM or internal store), they have almost entirely displaced analog computers, and computer programming, or coding has arisen as another human profession.

Since computers were rare in this era, the solutions were often hard-coded into paper forms such as graphs and nomograms, which could then allow analog solutions to problems, such as the distribution of pressures and temperatures in a heating system.
Some of the most widely deployed analog computers included devices for aiming weapons, such as the Norden bombsight and Fire-control systems for naval vessels. Some of these stayed in use for decades after WWII. One example is the Mark I Fire Control Computer, deployed by the United States Navy on a variety of ships from destroyers to battleships.
Other examples included the Heathkit EC-1, and the hydraulic MONIAC Computer.
