Brief History of Computer by Ajiboye Daud

LITERATURE reexamination OF COMPUTER HARDWARE Computers work evolved from the fundamental principles of numerical calculation and lyric processing. The reason placements of today ar an outcome of the efforts and intellect of mathematicians, logicians, linguists and technologists from all over the world. Computer annals comprises the evolutionary journey of computing frames, the timeline of op date of referenceting organisations as well as the history behind the suppuration of a great variety of figurer software and hardware. Bellow is the computing device history in picture and the evolution of computers. How did the different types of computers evolve?Here is a brief overview of the progress of computing technology from calculators of the 18th century right up to the modern-day digital port equal to(p) computers. Year Technology Used in front 1801 Calculators were the earliest computing devices. They were the only computation tools for long categorys in the front place the creation of computers. 1801 The familys that followed were dominated by the use of punched cards for computing. The users utilise to submit programming assignments to a computer centre using gobs of cards. The programs used to be queued for processing and execution. 1930 1960 Desktop mechanical calculators were built during the 1930s.During the mid-fifties and the 60s, electronic desktop calculators came up. Analog computational technologies predominated this tip. 1940 1960 This span of time witnessed the result of the digital computing technology. Zuse Z3, ENIAC and EDSAC were some of the early digital computers. * First-generation computers were ground on the von Neumann architecture. * The second generation computers were characterized by the replacement of vacuum render by bipolar transistors. They were composed of printed circuit boards. After 1960 These years witnessed the emergence of the third generation computers.They were based on integrated circui ts. Computer systems of this period had large storage capacities and high processing powers. Multi-core CPUs became available in the twenty- setoff off century. Laptops, palmtops, handheld PCs, notebook computers and tablet PCs are popular today. Computer climb upment still continues. Let us now get wind at the history and timeline of computing systems. before moving ahead, it will be interesting to chicane when was the first computer made Year Event 2400 BC Abacus, the first known calculator was invented in Babylonia. It was a major step towards the era of computing that was to follow. 500 BC Panini, an ancient Indian Sanskrit grammarian came up with the predecessor of the modern formal style theory. 300 BC Pingala invented the double star number system that serves as the foundation of computing systems the world over. 1614 crapper Napier designed the system of movable rods, which used algorithms to perform the basic mathematical operations. 1622 William Oughtred invente d slide rules. 1822 Charles Babbage devised the first mechanical computer. 1937 John V. Atanasoff devised the first digital electronic computer 1939 Atanasoff and Clifford Berry came up with the ABC prototype. 1941 The electromechanical Z machines by Konrad Zuse proved being an primary(prenominal) step in the evolution of computers. 1943 Colossus, which was able to decode German messages, was designed at Bletchley Park in Britain. 1944 Harvard object I, a computer with lesser programmability was designed. 1945 John von Neumann described a stored program architecture, for the first time ever. This architecture was the heart of the computer systems authentic thereafter. This architecture, which came to be known as the von Neumann architecture is a disassemble of every computer till today. 1946 The Ballistics Research Laboratory of the get together States came up with the Electronic Numerical Integrator and Computer (ENIAC). It was the first frequent purpose electronic compu ter but had an inflexible architecture. 1950 The US field Bureau of Standards came up with the Standards Electronic/Eastern Automatic Computer (SEAC). It was the first computer using diodes for handling logic. 1951 Lynos Electronic Office (LEO), the first credit line computer was substantial by John Simmons and T. Raymond Thompson. UNIVAC I, the first commercial computer was designed in the United States by John Presper Eckert and John W.Mauchly.

Transistors made computers energy-efficient. 1958 Advanced Research Projects Agency (ARPA) was formed. This year in like manner witnessed the fashioning of the first silicon chip by Jack Kilby and Robert Noyce. 1968 DEC tacked the first mini computer known as PDP-8 1969 The US Department of defense mechanism founded the Advanced Research Projects Agency Network (ARPANET). It was established with int ent to develop a computer network and is the predecessor of the Internet. 1971 Microcomputers came up with microprocessors and Ted Hoff at Intel, introduced 4-bit 4004. 1972 This year witnessed the creation of 8080 microprocessors by Intel. 1973 A minicomputer that was called Xerox low-pitched was essential during this year. It was an classical milest matchless in the development of personal computers. 1974 Researchers at the Xerox Palo Alto Research Center came up with Alto, which was the first workstation with an inbuilt mouse. It had a pretty amount of storage capacity and offered menus and icons. It could to a fault connect to a network. 1975 Altair came up with the first portable computer. The foundation of the present-day relationship between portability and computing was laid way back in 1975 Tandem computers, the first computers with online dealings processing capacities were born during this period. 1979 By 1979, more than half a one thousand million computers wer e in use in the United States. This number crossed 10 million by 1983. 1981 The American National Standards Institute (ANSI) was founded. It was during the same year that the first 32-bit chip was introduced by Hewlett-Packard. 1982 Intel announced the 80286 processor. 1983 In this year, the Time clipping nominated personal computer for the title machine of the year. 1985 Intel introduced the 80386 processor that consists of a 16MHz processor. 1990 The World Wide Web was born. Tim Berners-Lee, a researcher at CERN, highly-developed HTML. He came up with specifications such as URL and HTTP. He based the World Wide Web on enquiry-based system that used hypertext and enabled the great unwashed to collaborate over a network. His first web server and browser became available to the public. Till date The development of newer versions of computer systems continues. An operational system is that software component of a computer system, which deals with the management of the differen t computer processes and the sharing of computer resources. It hosts computer applications and handles computer hardware. Take a look at the major events in the history of direct systems. Before exit ahead, you might like to take a quick look at the different types of operate systems. Year Event 1954 MIT came up with their operating system for UNIVAC 1103. 1964 Dartmouth timesharing operating system was developed. 1965 Multics was announced.

Windows ME, which was sold during this year, was the last operating syst em in the Windows 9x line. Red Hat Linux 6. 2E also came up during 2000. 2001 Windows XP was launched and soon gained a broad popularity. Windows XP 64-bit edition followed in 2002. 2002 Windows XP Service Pack 1 was released in 2002. 2003 2003 witnessed the launch of the Windows 2003 Server as also the release of Red Hat enterprise Linux 3. 2004 Windows XP Service Pack 2 was released in 2004. 2006 Windows horizon hit the markets 2008 Windows Vista Service Pack 1 and Windows Server 2008 came up in 2008. It was also during this very year that Windows XP Service Pack 3 was released. Computers have everlastingly been the most efficient computational devices. They have high processing powers and are able to run and execute large programs. Programming languages serve as the means to write programs on computer systems. Thus, it is important to look at the timeline of the development of some of the major programming languages.Following is an overview of the important events in the history of computer languages. Year Programming Language Developed Before 1950 The ENIAC coding system was primarily used in computing 1954-54 Fortran 0 was designed by a team at IBM. Fortran Implementation was developed by John Backus at IBM in 1957. 1956-58 John McCarthy came up with the design of LISP. 1959 COBOL concept came up followed by its implementation that was developed by the Codasyl commission in 1960. The LISP implementation was developed in 1959. LISPs successor, Common LISP, came up afterwards in 1984. 1964 IBM came up with PL/I concept. PL/M followed years later in 1972. 1964 also saw the development of BASIC by Kemeny and Kurtz. 1969 ken Thompson developed the B language. 1970 This was when Pascal was developed. 1972 It was during 1972 that Smalltalk and Prolog were developed. One of the most important events in the history of computing was the development of C language. It was developed by Dennis Ritchie in 1972. 1975 Scheme, the successor of LISP came up in 1975 as also Modula, the successor of Pascal. 1978 SQL was developed at IBM in 1978. 1979 REXX and AWK came up in 1979. 1980-83 C with classes was developed in 1980. Objective-C came up in 1982. 1983 witnessed the development of C++, one of the very popular languages till date. 1985 PostScript and Object Pascal hold up to 1985. 1987 Perl that derives some of its features from C, as also from AWK, sed and sh evolved in 1987. 1991 Van Rossum came up with Python. ocular Basic, developed by Alan Cooper, came up in the same year. 1993 Ruby, which is considered a successor of Smalltalk and Perl, came up in 1993. 1994 PHP was born in 1994. 1995 ColdFusion belongs to 1995.It was during this year that James Gosling at Sun Microsystems came up with Java. 1996 Javascript was born in this year. ECMAScript, its successor came up in 1997. 1999 XSLT, a language based on XML by the W3C and the Game manufacturing business Language by Mark Overmars were born in 1999. 2000 The D lan guage and C came up in 2000. 2006 The development of Windows PowerShell by Microsoft was one of the probatory events in computing that took place in 2006. Looking at the apace advancing computing technology, we can surely say that the future of computers is exit to be as glorious as their history.
