History

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 (see picture below). 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. 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 laptop/notebook was the Grid Compass 1100 (called the GRiD) and was designed in 1979 by a British industrial designer, Bill Moggridge. The computer didn’t start selling until 1982, then featuring a 320×200 screen, an Intel 8086 processor, 340 KB of magnetic bubble memory (a now obsolete, non-volatile memory type) and a 1200 bps modem. It weighed 5 kg (11 lb) and cost $8-10,000. The GRiD was mainly used by NASA and the US military. 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 processor with 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. The first web server was a NeXT workstation that Tim Berners-Lee used when he invented the World Wide Web at CERN. The first web page was put online on August 6, 1991.

The computer had a note on it that said, “This machine is a server. DO NOT POWER IT DOWN!!” Understandable, considering that if you had shut it down in the early days you would have shut down the entire WWW.
Job description Computer hardware engineers develop, design, test and perform research to build or improve computer hardware. Such as the ones used for computer systems, chips, etc. They are responsible for computer hardware found in accessories such as printers and modems. As a computer hardware engineer you can get called upon to supervise how computer equipment are built and manufactured. Another task they work at is analyzing and testing finishing products to ensure they’ll meet the expectations with the proper set of specifications and to create and implement rules and procedure to correct and improve existing systems. Usually works in a climate-controlled and or laboratories due to necessary environment requirement of the electronic components which they will work with. The computer engineer normally works a 5-day, 40-hour week although long hours and tight deadlines can be a part of this job, depending on the nature of the project. However, an engineer’s schedule usually allots enough time for experimentation and testing of prototype models of potential equipment. The starting salary for a computer hardware engineer is among the highest of all college graduates. It is critical for engineers to continue their education to keep up with ever-changing improvements in technology. The average hourly wage is $48.75, with an annual wage of $101,410. In fact, the...
