SECRETARIA DE FINANÇAS DO RECIFE Empresa Municipal de Informática - EMPREL
Histórico
A rede de história da EMPREL começou a ser tecida em 1963, quando a Prefeitura do Recife adquiriu seu primeiro computador, um modelo IBM 1401, para a antiga Divisão de Mecanização.
Em 9 de dezembro de 1969, uma lei municipal, finalmente institucionalizou a então Empresa Municipal de Processamento Eletrônico.
Em janeiro de 1970, no velho casarão 271 da rua da União, a EMPREL engatinhava no gerenciamento da arrecadação de tributos e na folha de pagamento do funcionalismo municipal.
Passados 26 anos da sua criação e hoje denominada de Empresa Municipal de Informática, a EMPREL dispõe de eficiente parque tecnológico, composto de redes de microcomputadores, Geoprocessamento, Multimídia e é provedor público de acesso à Internet.
Atuação
Rede de Cidadania para auxiliar o cidadão, uma rede de serviços foi desenvolvida, com pesquisas mensais de preços de produtos nos supermercados ou de produtos de época. Na educação, toda renovação de matrícula já é automática, e os alunos das escolas municipais aprendem informática.
Rede de Saúde
Desde o controle de campanhas de vacinação e epidemiológico até o gerenciamento dos postos de saúde comunitários, uma rede de sistemas cuida bem da saúde do Recife. O Projeto Cooperado de Saúde é outra atividade que vai ajudar a saúde pública de todo o país.
Rede Urbanística
Transportes urbanos, na manutenção e no acompanhamento das obras. Além, claro, de todo planejamento.
Rede de Gerenciamento
A arrecadação e a aplicação dos impostos também contam com eficiente rede de sistemas. Inclusive com autoatendimento.

The Five Generations of Computers
Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices.
The history of computer development is often referred to in reference to the different generations of computing devices. Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices. Read about each generation and the developments that led to the current devices that we use today.
First Generation (1940-1956) Vacuum Tubes
The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.
The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.
Second Generation (1956-1963) Transistors
Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their firstgeneration predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.
Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.The first computers of this generation were developed for the atomic energy industry.
Third Generation (1964-1971) Integrated Circuits
The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.
Fourth Generation (1971-Present) Microprocessors
The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip.
In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.
As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.
Fifth Generation (Present and Beyond) Artificial Intelligence
Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.

CANDIDATO SOFRE E COMO...
Autor desconhecido
Pontualmente, às 7h, o portão se abre. No corre-corre, corpos se batem, atropelam-se, quase tombam. Cada um procura a sua sala, a maioria com passos acelerados, e poucos, a passos de tartaruga. Esquecimento de caneta, de identidade, de alguma documentação exigida pelo processo gera tumulto em algumas salas. Os responsáveis agilizam providências pertinentes. Para muitos, é momento de tensão, de expectativa. É momento de na “pena” e no papel demonstrarem suas “aprendizagens”. O candidato pena na “pena”, sobretudo aqueles desprovidos de conteúdo. Estes apelam para os neurônios, mas nada têm o que dizer. Sala silenciosa, alguns tentam espichar o pescoço em busca de respostas, outros se fixam de tal forma nas questões que o mundo parece “morrer”. Suor para alguns. Dor de cabeça para outros. Poucos são os que mantêm a calma. E ainda dizem que vida de candidato é moleza.
