20 21 The Z3 was built with 2000 relays, implementing a 22 bit word length that operated at a clock frequency of about 510. 22 Program code was supplied on punched film while data could be stored in 64 words of memory or supplied from the keyboard. It was quite similar to modern machines in some respects, pioneering numerous advances such as floating point numbers. Rather than the harder-to-implement decimal system (used in Charles Babbage 's earlier design using a binary system meant that Zuse's machines were easier to build and potentially more reliable, given the technologies available at that time. 23 The Z3 was Turing complete. 24 25 Vacuum tubes and digital electronic circuits Purely electronic circuit elements soon replaced their mechanical and electromechanical equivalents, at the same time that digital calculation replaced analog.

A dozen of these devices were built before their obsolescence became obvious. By the 1950s the success of digital electronic computers had spelled the end for most analog computing machines, but analog computers remained full in use during the 1950s in some specialized applications such as education ( control systems ) and aircraft ( slide rule ). Digital computers Electromechanical by 1938, the United States navy had developed an electromechanical analog computer small enough to use aboard a submarine. This was the torpedo data computer, which used trigonometry to solve the problem of firing a torpedo at a moving target. During World War ii similar devices were developed in other countries as well. Replica of Zuse 's Z3, the first fully automatic, digital (electromechanical) computer. Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2, created by german engineer Konrad Zuse in 1939, was one of the earliest examples of an electromechanical relay computer. 19 In 1941, zuse followed his earlier machine up with the Z3, the world's first working electromechanical programmable, fully automatic digital computer.

Nevertheless, his son, henry babbage, completed a simplified version of the analytical engine's computing unit (the mill ) make in 1888. He gave a successful demonstration of its use in computing tables in 1906. Analog computers During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation. However, these were not programmable and generally lacked the versatility and accuracy of modern digital computers. 18 The first modern analog computer was a tide-predicting machine, invented by sir William Thomson in 1872. The differential analyser, a mechanical analog computer designed to solve differential equations by integration using wheel-and-disc mechanisms, was conceptualized in 1876 by james Thomson, the brother of the more famous Lord Kelvin. 14 The art of mechanical analog computing reached its zenith with the differential analyzer, built. Hazen and Vannevar Bush at mit starting in 1927. This built on the mechanical integrators of James Thomson and the torque amplifiers invented.

After working on his revolutionary difference engine, designed to aid in navigational calculations, in 1833 he realized that a much more general design, an Analytical Engine, was possible. The input of programs and data was to be provided to the machine via punched cards, a method being used at the time to direct mechanical looms such as the jacquard loom. For output, the machine would have a printer, a curve plotter and a bell. The machine would also be able to punch numbers onto cards to be read in later. The Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete. 16 17 The machine was about a century ahead of its time. All the parts for his machine had to be made by hand this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with the decision of the British government to cease funding. Babbage's failure to complete the analytical engine can be chiefly attributed to difficulties not only gpa of politics and financing, but also to his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow.

It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location. The differential analyser, a mechanical analog computer designed to solve differential equations by integration, used wheel-and-disc mechanisms to perform the integration. In 1876 Lord Kelvin had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators. 14 In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Starting in the 1920s, vannevar Bush and others developed mechanical differential analyzers. First computing device Charles Babbage, an English mechanical engineer and polymath, originated the concept of a programmable computer. Considered the " father of the computer 15 he conceptualized and invented the first mechanical computer in the early 19th century.

A combination of the planisphere and dioptra, the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer 7 8 and gear -wheels was invented by Abi bakr time of Isfahan, persia in 1235. 9 Abū rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, 10 an early fixed- wired knowledge processing machine 11 with a gear train and gear-wheels. The sector, a calculating instrument used for solving problems in proportion, trigonometry, multiplication and division, and for various functions, such as squares and cube roots, was developed in the late 16th century and found application in gunnery, surveying and navigation. The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. A slide rule The slide rule was invented around 16201630, shortly after the publication of the concept of the logarithm. It is a hand-operated analog computer for doing multiplication and division.

As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions. Slide rules with special scales are still used for quick performance of routine calculations, such as the E6B circular slide rule used for time and distance calculations on light aircraft. In the 1770s pierre jaquet-Droz, a swiss watchmaker, built a mechanical doll ( automata ) that could write holding a quill pen. By switching the number and order of its internal wheels different letters, and hence different messages, could be produced. In effect, it could be mechanically "programmed" to read instructions. Along with two other complex machines, the doll is at the musée d'Art et d'Histoire of neuchâtel, switzerland, and still operates. 13 The tide-predicting machine invented by sir William Thomson in 1872 was of great utility to navigation in shallow waters.

2 History main article: History of computing hardware Pre-20th century devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers. The earliest counting device was probably a form of tally stick. Later record keeping aids throughout the fertile Crescent included calculi (clay spheres, cones, etc.) which represented counts of items, probably livestock or grains, sealed in hollow unbaked clay containers. 3 4 The use of counting rods is one example. The Chinese suanpan (the number represented on this abacus is 6,302,715,408) The abacus was initially used for arithmetic tasks. The roman abacus was developed from devices used in Babylonia as early as 2400.


Since then, many other forms of reckoning boards or tables have been invented. In a medieval European counting house, a checkered cloth would be placed on a table, and markers moved around on it according to certain rules, as an aid to calculating sums of money. The Antikythera mechanism is believed to be the earliest mechanical analog "computer according to derek. 5 It was designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to circa 100. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later. Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use. The planisphere was a star chart invented by Abū rayhān al-Bīrūnī in the early 11th century. 6 The astrolabe was invented in the hellenistic world in either the 1st or 2nd centuries bc and is often attributed to hipparchus.

More sophisticated electrical machines did specialized analog calculations in the early 20th century. The first digital electronic calculating machines were developed during World War. The speed, power, and sarojini versatility of computers have been increasing dramatically ever since then. Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (cpu and some form of memory. The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices include input devices (keyboards, mice, joystick, etc. output devices (monitor screens, printers, etc. and input/output devices that perform both functions (e.g., the 2000s-era touchscreen ). Peripheral devices allow information to be retrieved from an external source and they enable the result of operations to be saved and retrieved.

programs. These programs enable computers to perform an extremely wide range of tasks. Computers are used as control systems for a wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer-aided design, and also general purpose devices like personal computers and mobile devices such as smartphones. Early computers were only conceived as calculating devices. Since ancient times, simple manual devices like the abacus aided people in doing calculations. Industrial revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms.

The common Core State Standards for English Language Arts literacy in History/Social Studies, Science, and Technical Subjects (the standards) represent the next generation of K12 standards essay designed to prepare all students for success in college, career, and life by the time they graduate from high. The common Core asks students to read stories and literature, as well as more complex texts that provide facts and background knowledge in areas such as science and social studies. Students will be challenged and asked questions that push them to refer back to what theyve read. This stresses critical-thinking, problem-solving, and analytical skills that are required for success in college, career, and life. The standards establish guidelines for English language arts (ELA) as well as for literacy in history/social studies, science, and technical subjects. Because students must learn to read, write, speak, listen, and use language effectively in a variety of content areas, the standards promote the literacy skills and concepts required for college and career readiness in multiple disciplines. The college and Career readiness Anchor Standards form the backbone of the ela/literacy standards by articulating core knowledge and skills, while grade-specific standards provide additional specificity. Beginning in grade 6, the literacy standards allow teachers of ela, history/social studies, science, and technical subjects to use their content area expertise to help students meet the particular challenges of reading, writing, speaking, listening, and language in their respective fields. It is important to note that the grade 612 literacy standards in history/social studies, science, and technical subjects are meant to supplement content standards in those areas, not replace them.
