Last updated: December 25, I t was probably the worst prediction in history. Back in the s, Thomas Watson, boss of the giant IBM Corporation, reputedly forecast that the world would need no more than "about five computers. To be fair to Watson, computers have changed enormously in that time. In the s, they were giant scientific and military behemoths commissioned by the government at a cost of millions of dollars apiece; today, most computers are not even recognizable as such: they are embedded in everything from microwave ovens to cellphones and digital radios. What makes computers flexible enough to work in all these different appliances?

Perhaps the most visible contribution, however, came in the form of the instrument unit or guidance system for the famed Saturn V rocket that propelled humans to the Moon. Three feet tall, 22 feet in diameter and weighing about pounds kg , the Saturn V Instrument Guide was the guidance system constructed by IBM that helped steer the astronauts of Apollo It held components built by IBM and 60 other companies.

IBM was the prime contractor for development and fabrication of the instrument unit—a vital piece for the proper flight of Apollo It contained navigation, guidance, control and sequencing equipment for the launch vehicle and would be mounted atop the third stage rocket between the Saturn V and the Apollo spacecraft.

Here, IBMers conduct a systems test on the instrument unit. Beyond guidance systems, the instrument unit also provided command and sequence of vehicle functions, telemetry and environmental control.

The Apollo spacecraft will later be installed directly above the instrument unit. This illustration shows the major components of the instrument unit and their configuration. The instrument unit kept the Saturn V launch vehicle properly functioning and on its course, sending the first men to the Moon. The instrument unit was composed of three degree segments, each consisting of thin-walled aluminum alloy face sheets bonded over a core of aluminum honeycomb.

This division was accountable for the fabrication and assembly of the unit, system testing, and integration and checkout of the unit with the launch vehicle. Johnson Space Center—that collected, processed and sent to Mission Control information to direct every phase of an Apollo mission. The RTCC was so fast, there was virtually no time between receiving and solving a computing problem.

In , for the first time, a guidance computer rode into space with astronauts and was used to supply flight information so command pilot Virgil E. Grissom could maneuver his spacecraft.

The IBM digital computer issued signals 25 times a second to help keep the Saturn on course during launch, and was primarily responsible for prelaunch checkout, booster guidance and Saturn V lunar trajectory injection. Apollo flights had so much information to relay, that their computers had to report in an electronic form of shorthand. Receiving this enormous amount of data was a powerful IBM computer whose sole task was to translate the shorthand into meaningful information for Apollo flight controllers.

Today's world runs on computers. Nearly every aspect of modern life involves computers in some form or fashion. As technology is advancing, the scale of computer use is increasing.

The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers. Before the 20th century, most calculations were done by humans. Early mechanical tools to help humans with digital calculations, like the abacus , were called "calculating machines", called by proprietary names, or referred to as calculators. The machine operator was called the computer. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic operation, then manipulate the device to obtain the result.

Chapter 7. Telecommunications, the Internet, and Information System Architecture. The electronic transmission of information over distances, called telecommunications, has become virtually inseparable from computers: Computers and telecommunications create value together. Components of a Telecommunications Network.

Computer Hardware Engineers

That same year in Germany, engineer Konrad Zuse built his Z2 computer, also using telephone company relays. Their first product, the HP A Audio Oscillator, rapidly became a popular piece of test equipment for engineers. In , Bell Telephone Laboratories completes this calculator, designed by scientist George Stibitz. Stibitz stunned the group by performing calculations remotely on the CNC located in New York City using a Teletype terminal connected via to New York over special telephone lines. This is likely the first example of remote access computing. The Z3, an early computer built by German engineer Konrad Zuse working in complete isolation from developments elsewhere, uses 2, relays, performs floating point binary arithmetic, and has a bit word length.

Perhaps the most visible contribution, however, came in the form of the instrument unit or guidance system for the famed Saturn V rocket that propelled humans to the Moon.

The baccalaureate Curriculum Guidelines for Undergraduate Degree Programs in Computer Engineering report provides insights into the nature of this field:. Computer engineering is defined as the discipline that embodies the science and technology of design, construction, implementation, and maintenance of software and hardware components of modern computing systems and computer-controlled equipment. Computer engineering has traditionally been viewed as a combination of both computer science CS and electrical engineering EE. It has evolved over the past three decades as a separate, although intimately related, discipline. Computer engineering is solidly grounded in the theories and principles of computing, mathematics, science, and engineering and it applies these theories and principles to solve technical problems through the design of computing hardware, software, networks, and processes. Historically, the field of computer engineering has been widely viewed as "designing computers. The successful miniaturization of silicon devices and their increased reliability as system building blocks has created an environment in which computers have replaced the more conventional electronic devices. These applications manifest themselves in the proliferation of mobile telephones, personal digital assistants, location-aware devices, digital cameras, and similar products. It also reveals itself in the myriad of applications involving embedded systems, namely those computing systems that appear in applications such as automobiles, large- scale electronic devices, and major appliances.

History of computing

A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks.

A computer is a machine for manipulating data according to a list of instructions. Computers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers.

A computer is a programmable device that can automatically perform a sequence of calculations or other operations on data once programmed for the task. It can store, retrieve, and process data according to internal instructions. A computer may be either digital, analog, or hybrid, although most in operation today are digital. Digital computers express variables as numbers, usually in the binary system. They are used for general purposes, whereas analog computers are built for specific tasks, typically scientific or technical. The term "computer" is usually synonymous with digital computer, and computers for business are exclusively digital. The core, computing part of a computer is its central processing unit CPU , or processor. It comprises an arithmetic-logic unit to carry out calculations, main memory to temporarily store data for processing, and a control unit to control the transfer of data between memory, input and output sources, and the arithmetic-logic unit. A computer is not fully functional without various peripheral devices, however. These are typically connected to a computer through cables, although some may be built into the same unit with the CPU. These include devices for the input of data, such as keyboards, mice, trackballs, scanners, light pens, modems, magnetic strip card readers, and microphones, as well as items for the output of data, such as monitors, printers, plotters, loudspeakers, earphones, and modems.

The Apollo Missions

In fact, calculation underlies many activities that are not normally thought of as mathematical. Walking across a room, for instance, requires many complex, albeit subconscious, calculations. Computers, too, have proved capable of solving a vast array of problems, from balancing a checkbook to even—in the form of guidance systems for robots—walking across a room. Before the true power of computing could be realized, therefore, the naive view of calculation had to be overcome. The inventors who laboured to bring the computer into the world had to learn that the thing they were inventing was not just a number cruncher, not merely a calculator. For example, they had to learn that it was not necessary to invent a new computer for every new calculation and that a computer could be designed to solve numerous problems, even problems not yet imagined when the computer was built.

Hardware is the most visible part of any information system: the equipment such as computers, scanners and printers that is used to capture data, transform it and present it to the user as output. Although we will focus mainly on the personal computer PC and the peripheral devices that are commonly used with it, the same principles apply to the complete range of computers:. And we are already moving into the age of wearable computers for medical or security applications, embedded computers in appliances ranging from motor cars to washing machines, and the smart card which will provide identification, banking facilities, medical records and more! Data may enter an information system in a variety of different ways, and the input device that is most appropriate will usually depend on the type of data being entered into the system, how frequently this is done, and who is responsible for the activity.

What They Do : Computer hardware engineers research, design, develop, and test computer systems and components. Work Environment : Computer hardware engineers usually work in research laboratories that build and test various types of computer models. Most work in computer systems design services and in manufacturing.
