Computers are wonderful machines. Initially designed for internal use by HP employees, co-founder Bill Hewlett issues a challenge to his engineers in 1971: fit all of the features of their desktop scientific calculator into a package small enough for his shirt pocket. The differential analyser , a mechanical analog computer designed to solve differential equations by integration , used wheel-and-disc mechanisms to perform the integration.
The first digital electronic calculating machines were developed during World War II The speed, power, and versatility of computers have been increasing dramatically ever since then. The ancient Greek -designed Antikythera mechanism , dating between 150 and 100 BC, is the world’s oldest analog computer.
In 1999, Dell became the largest personal computer seller when they took over Compaq computers. However, these were not programmable and generally lacked the versatility and accuracy of modern digital computers. A joint project of England’s Manchester University, Ferranti Computers, and Plessey, Atlas comes online nine years after Manchester’s computer lab begins exploring transistor technology.
Used for science and engineering as well as simple data processing, the LGP-30 was a bargainâ€ at less than $50,000 and an early example of a â€˜personal computer,’ that is, a computer made for a single user. From the extremely powerful C language, it’s object-oriented descendants – C# and C++, Java, to newborns like Python, programming languages come in all varieties and flavors, designed to solve a range of problems in every computable domain.

Computer programmers write programs in a variety of computer languages, such as C++ and Java. With an order for 50 assembled systems from Mountain View, California computer store The Byte Shop in hand, the pair started a new company, naming it Apple Computer, Inc. All three PowerBooks introduced featured a built-in trackball, internal floppy drive, and palm rests, which would eventually become typical of 1990s laptop design.
For example, wireless keyboards for your desktop computers or tablets make easy work of typing emails, documents and more. After the success of the first LEO, Lyons went into business manufacturing computers to meet the growing need for data processing systems in business.
The TRS-80 was priced at $599.95, included a Z80 microprocessor, video display, 4 KB of memory, a built-in BASIC programming language interpreter, cassette storage, and easy-to-understand manuals that assumed no prior knowledge on the part of the user.
Personal Computer gaming is and always will be the most powerful gaming platform. They are generally either translated into machine code by a compiler or an assembler before being run, or translated directly at run time by an interpreter Sometimes programs are executed by a hybrid method of the two techniques. The resulting Jacquard loom was an important step in the development of computers because the use of punched cards to define woven patterns can be viewed as an early, albeit limited, form of programmability.
Large-scale automated data processing of punched cards was performed for the US Census in 1890 by tabulating machines designed by Herman … Read More..
