The Inventors of Computer hardware
The first computer mouse
The first computer mouse was invented in 1963 by Douglas Engelbart at the Stanford Research Institute. (He is also one of the inventors of hypertext.) The first mouse used two wheels positioned at a 90-degree angle to each other to keep track of the movement. The ball mouse wasn’t invented until 1972, and the optical mouse was invented circa 1980 although it didn’t come to popular use until much later.
Douglas Engelbart never received any royalties for his invention and his patent had run out by the time the mouse became commonplace in the era of home PCs.
Intel with the help of Ted Hoff Introduces the first microprocessor which is called CPU. A CPU is responsible for handling all instructions it receives from hardware and software running on the computer. The first one introduced was the Intel 4004 on november 15,1971. The 4004 had 2,300 transistors and performed 60,000 operations per second (OPS), addressed 640 bytes of memory, and cost $200
The first portable computer
Well, perhaps that should be “movable” computer… The IBM 5100 Portable Computer was introduced in 1975, weighed 25 kg (55 lb), was the size of a small suitcase and needed external power to operate. It held everything in the same unit, packing in a processor, ROM (several hundreds of KB) and RAM (16-64 KB), a five-inch CRT display, keyboard and a tape drive, which was an amazing feat at the time. It also came with built-in BASIC and/or APL. The different models of the IBM 5100 sold for $8,975 – $19,975.
The First IBM computer
The IBM Personal Computer was introduced in 1981 as the IBM 5150. The platform became so pervasive in the 80s that although the term “personal computer” had been in use since the early 70s, a PC became synonymous with an IBM PC-compatible computer.
During its development, the IBM 5150 had been internally referred to as “Project Chess” and was created by a team of 12 people headed by Don Estridge and Larry Potter. To speed up development and cut costs, IBM had decided to use off-the-shelf parts, something that they normally wouldn’t do.
The first IBM PC had an Intel 8088 processor, 64 KB of RAM (extendible to 256 KB), a floppy disk drive (which could be used to boot the computer with a rebranded version of MS-DOS (PC-DOS)) and a CGA or monochrome video card. The machine also had a version of Microsoft BASIC in ROM. On the first IBM PC the optional 10 MB hard disk drive could only be installed if the original power supply was replaced (the original one was too weak).
The First Apple computer
The first Apple personal computers (Apple I) were designed and hand-built by Steve Wozniak. The Apple I went on sale in 1976 for the price of $666.66. Only about 200 units were produced. The Apple I was basically just a motherboard with a processor, a total of 8KB of RAM, a display interface and some additional functionality. To have a working computer, the buyer would have to add a power supply, a keyboard and a display (and a case to keep mount it all in).
Nvidia NV1, manufactured by SGS-THOMSON Microelectronics under the model name STG2000, was a multimedia PCI card released in 1995 and sold to retail as the Diamond Edge 3D. It featured a complete 2D/3D graphics core based upon quadratic texture mapping, VRAM or FPM DRAM memory, an integrated 32-channel 350 MIPS playback-only sound card, and a Sega Saturn compatible joypad port. As such, it was intended to replace the 2D graphics card, Sound Blaster-compatible audio systems, and 15-pin joystick ports, then prevalent on IBM PC compatibles.
First wireless mouse
The first wireless mouse was released in 1999 by Microsoft. which is cordless and features optical sensors instead of trackball and armed with long lasting batteries and un-paralleled accuracy.
The first trackball
The trackball was actually invented 11 years BEFORE the mouse, in 1952. It was invented by Tom Cranston and Fred Longstaff as part of a computerized battlefield information system called DATAR, initiated by the Canadian Navy. It used a standard five-pin bowling ball as its trackball, which is smaller than the more common 10-pin bowling ball.
First integrated circuit
An integrated chip was introduced as a concept by Geoffrey dummer a british radar engineer on may 7 and first demonstrated September 12, 1958. An integrated chip is a package that contains many circuits, pathways, transistors and other electronic components all working together to perform a particular function or a series of functions. Ic's are the building blocks of computer hardware.
In 1960,IBM Develops the first automatic mass-production facility of transistors in new york
Intel Corporation is founded in 1968 by Robert Noyce and Gorden moore
On May 1, 1969,foundation of Advanced Micro Devices (AMD). The founders are :
The Intel 4004 microprocessor
The first mouse
Random Access Memory (RAM)
RAM is a form of computer data storage. A random access device allows stored data to be accessed directly in any random order. In 1968, IBM's Robert Dennard invented a one transistor DRAM cell. DRAM stands for Dynamic RAM. Dynamic RAM is now the standard memory chip for personal computers, replacing the magnetic core memory.
The birth of Microsoft
Microsoft was founded in April 4, 1975. In Albuquerque, New Mexico, united states by bill gates and Paul Allen
Facebook was founded in February 4, 2004 in Cambridge, Massachusetts, united states, by:
Nvidia was founded in 1993 in Santa Clara, California by
First Nvidia graphics card
Released in 1996, Desinged by Compaq,Dec, IBM, Intel, Microsoft, NEC and Nortel
The first Ipod was released in 2001, Ordered by Steve Jobs and desinged by Engineering cheif Jon Rubinstein
