Contact Us Importance of computers Today is the world of computers as every field is dependent on it.
Our shoddy thinking about the brain has deep historical roots, but the invention of computers in the s got us especially confused. For more than half a century now, psychologists, linguists, neuroscientists and other experts on human behaviour have been asserting that the human brain works like a computer.
Thanks to evolution, human neonates, like the newborns of all other mammalian species, enter the world prepared to interact with it effectively. It prefers the sound of voices to non-speech sounds, and can distinguish one basic speech sound from another.
We are, without doubt, built to make social connections. A healthy newborn is also equipped with more than a dozen reflexes — ready-made reactions to certain stimuli that are important for its survival. It turns its head in the direction of something that brushes its cheek and then sucks whatever enters its mouth.
It holds its breath when submerged in water. It grasps things placed in its hands so strongly it can nearly support its own weight. Perhaps most important, newborns come equipped with powerful learning mechanisms that allow them to change rapidly so they can interact increasingly effectively with their world, even if that world is unlike the one their distant ancestors faced.
Senses, reflexes and learning mechanisms — this is what we start with, and it is quite a lot, when you think about it. If we lacked any of these capabilities at birth, we would probably have trouble surviving. But here is what we are not born with: Computers do all of these things, but organisms do not.
Computers, quite literally, process information — numbers, letters, words, formulas, images. Side by side, those three bytes form the word dog.
Computers, quite literally, move these patterns from place to place in different physical storage areas etched into electronic components. Sometimes they also copy the patterns, and sometimes they transform them in various ways — say, when we are correcting errors in a manuscript or when we are touching up a photograph.
The rules computers follow for moving, copying and operating on these arrays of data are also stored inside the computer. Forgive me for this introduction to computing, but I need to be clear: They really store and retrieve. They really have physical memories. They really are guided in everything they do, without exception, by algorithms.
Humans, on the other hand, do not — never did, never will. In his book In Our Own Imagethe artificial intelligence expert George Zarkadakis describes six different metaphors people have employed over the past 2, years to try to explain human intelligence.
In the earliest one, eventually preserved in the Bible, humans were formed from clay or dirt, which an intelligent god then infused with its spirit. The hydraulic metaphor persisted for more than 1, years, handicapping medical practice all the while.
In the s, the British philosopher Thomas Hobbes suggested that thinking arose from small mechanical motions in the brain. By the s, discoveries about electricity and chemistry led to new theories of human intelligence — again, largely metaphorical in nature. In the mids, inspired by recent advances in communications, the German physicist Hermann von Helmholtz compared the brain to a telegraph.
Predictably, just a few years after the dawn of computer technology in the s, the brain was said to operate like a computer, with the role of physical hardware played by the brain itself and our thoughts serving as software. Miller proposed that the mental world could be studied rigorously using concepts from information theory, computation and linguistics.
Although he acknowledged that little was actually known about the role the brain played in human reasoning and memory, he drew parallel after parallel between the components of the computing machines of the day and the components of the human brain.
Propelled by subsequent advances in both computer technology and brain research, an ambitious multidisciplinary effort to understand human intelligence gradually developed, firmly rooted in the idea that humans are, like computers, information processors.
This effort now involves thousands of researchers, consumes billions of dollars in funding, and has generated a vast literature consisting of both technical and mainstream articles and books.
The information processing IP metaphor of human intelligence now dominates human thinking, both on the street and in the sciences. There is virtually no form of discourse about intelligent human behaviour that proceeds without employing this metaphor, just as no form of discourse about intelligent human behaviour could proceed in certain eras and cultures without reference to a spirit or deity.
And like all the metaphors that preceded it, it will certainly be cast aside at some point — either replaced by another metaphor or, in the end, replaced by actual knowledge. They saw the problem.The Impact Of Computers In Our Daily Lives Computer Science Essay.

Many business organizations need computer to keep track of accounts, money and other stuff that they need. It has been noticed that business people use.
All our daily life activities are based on such online services and products. Computer changed our life 2 decades ago and now it is a necessity to use a computer in daily life to live.
