the first computer

The computer he created, an all-black cube was an important innovation. ENIAC was the most powerful calculating device built to that time. The Retina display became standard on most of the iPad, iPhone, MacBook, and Apple Watch product lines. Because of its electronic, as opposed to electromechanical, technology, it is over 1,000 times faster than any previous computer. When was the first personal computer invented? At the same press conference, IBM also announced 40 completely new peripherals for the new family. Apple’s inspiration for the Lisa and Macintosh computers came from the Xerox Alto.
The machine´s system of connections and switches let processors broadcast information and requests for help to other processors in a simulation of brain-like associative recall. Its “Williams-Kilburn tube” memory system was later adopted by several other early computer systems around the world.

One of the first commercially produced computers, the company´s first customer was the US Navy. The J-Phone line would quickly expand, releasing a flip-phone version just a month later. It featured a 5-inch display, 64 KB of memory, a modem, and two 5.25-inch floppy disk drives.The C64, as it is better known, sells for $595, comes with 64 KB of RAM and features impressive graphics.
A British government contract spurred its initial development but a change in government led to loss of funding and the second and only other Mark I was sold at a major loss to the University of Toronto, where it was re-christened FERUT.The Univac 1 is the first commercial computer to attract widespread public attention. With a screen resolution of up to 400 pixels-per-inch (PPI), Retina displays approached the limit of pixel visibility to the human eye. Designed to replace the 32-bit VAX architecture, the Alpha is a 64-bit reduced instruction set computer (RISC) microprocessor. The first computer, in the sense of a machine that can accept numbers and calculate their result, was not an electrical device, but a mechanical one. One of Britain's leading computer companies, Acorn continued the Archimedes line, which grew to nearly twenty different models, into the 1990s.

System control was provided through the Atlas Supervisor, which some consider to be the first true operating system.The Control Data Corporation (CDC) 6600 performs up to 3 million instructions per second —three times faster than that of its closest competitor, the IBM 7030 supercomputer. It would serve as the model for several other significant multi-processor systems that would be among the fastest in the world. On April 7, IBM announced five models of System/360, spanning a 50-to-1 performance range. While Apple sued to remove the Laser 128 from the market, they were unsuccessful and the Laser remained one of the very few Apple “clones” for sale.

The Nest Learning Thermostat is an early product made for the emerging “Internet of Things,” which envisages a world in which common everyday devices have network connectivity and can exchange information or be controlled. IBM’s initial investment of $5 billion was quickly returned as orders for the system climbed to 1,000 per month within two years. Foremost among its developments was Forrester’s perfection of magnetic core memory, which became the dominant form of high-speed random access memory for computers until the mid-1970s.Started in 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering of the University of Pennsylvania. Colossus reduced the time to break Lorenz messages from weeks to hours. In 1984, Michael Dell creates PC's Limited while still a student of the University of Texas at Austin. The DN100 is based on the Motorola 68000 microprocessor, high-resolution display and built-in networking - the three basic features of all workstations. The project became the One Laptop per Child Consortium (OLPC) founded by Nicholas Negroponte, the founder of MIT's Media Lab. It’s “chiclet” keyboard was also criticized for poor ergonomics. Throughout the 1960s and ‘70s, the ASR-33 was a popular and inexpensive choice of input and output device for minicomputers and many of the first generation of microcomputers. The AGC was one of the earliest uses of integrated circuits, and used core memory, as well as read-only magnetic rope memory. The PowerBook 100 was the entry-level machine, while the PowerBook 140 was more powerful and had a larger memory. The Zilog Z-80 could run any program written for the 8080 and included twice as many built-in machine instructions.Designed by Sunnyvale, California native Steve Wozniak, and marketed by his friend Steve Jobs, the Apple-1 is a single-board computer for hobbyists. It interfaced with a wide number of standard laboratory instruments, allowing customers to computerize their instrument systems. Franklin was able to undercut Apple's pricing even while offering some features not available on the original. Almost a million units were ordered on the day of release. Lenovo became the largest manufacturer of PCs in the world with the acquisition, later also acquiring IBM's server line of computers. The Relay Interpolator used 440 relays, and since it was programmable by paper tape, was used for other applications following the war.Curt Herzstark was an Austrian engineer who worked in his family’s manufacturing business until he was arrested by the Nazis in 1943. Called the “Model K” Adder because he built it on his “Kitchen” table, this simple demonstration circuit provides proof of concept for applying Boolean logic to the design of computers, resulting in construction of the relay-based Model I Complex Calculator in 1939. It was thus an important milestone in computing as soon Microsoft Windows and the Apple Macintosh would soon adopt the GUI as their user interface, making it the new paradigm for personal computing. Wilkes' ideas grew out of the Moore School lectures he had attended three years earlier. Remington Rand eventually sold 46 Univac 1s at more than $1 million each. The TRS-80 proved popular with schools, as well as for home use.
