Type of computer

Welcome to the WORLD OF TECHNOLOGY

Part of the inhumanity of the computer is that, once it is competently programmed and working smoothly, it is completely honest. Essential Question: Computer - How much we know about it? Computer is used in almost each and every sphere of life. It not only boosts our activities but also render a great help in our day to day life. It has become a part of our life to such an extent that we cannot think of our life without computers. It helps us in weather forecasting, national security, road safety measures and long distance personal interface. It helps us in assessment and evaluation of various scientific as well as statistical data. The repeated promises and delivery of newer, faster, or more versatile systems and software makes one hesitant to commit a system for fear of missing out for something better. Moreover this constant introduction of new systems tends to drive down the price of the old, so that even when we make a decision to buy, we may be concerned about paying too much for the system we have selected. MY MISSION Computers are introduced to the children from the 1st class. But the question raised is that HOW MANY CHILDREN & THE PEOPLE AROUND THIS WORLD KNOW EVERYTHING ABOUT COMPUTERS? Are they really aware of the basics of computer? My blog is based on the basics of Computer. My mission is to make children, of all ages, know more & more about the Computer which is so much used in our daily life. And pull them out of the games of Computer, introducing the rest of world of Computer. What is a Computer? In its most basic form a computer is any device which aids humans in performing various kinds of computations or calculations. In that respect the earliest computer was the abacus, used to perform basic arithmetic operations. Every computer supports some form of input, processing, and output. This is less obvious on a primitive device such as the abacus where input, output and processing are simply the act of moving the pebbles into new positions, seeing the changed positions, and counting. Regardless, this is what computing is all about, in a nutshell. We input information, the computer processes it according to its basic logic or the program currently running, and outputs the results. Modern computers do this electronically, which enables them to perform a vastly greater number of calculations or computations in less time. Despite the fact that we currently use computers to process images, sound, text and other non-numerical forms of data, all of it depends on nothing more than basic numerical calculations. Graphics, sound etc. are merely abstractions of the numbers being crunched within the machine; in digital computers these are the ones and zeros, representing electrical on and off states, and endless combinations of those. In other words every image, every sound, and every word have a corresponding binary code. There are a lot of terms used to describe computers. Most of these words imply the size, expected use or capability of the computer. While the term computer can apply to virtually any device that has a microprocessor in it, most people think of a computer as a device that receives input from the user through a mouse or keyboard, processes it in some fashion and displays the result on a screen. Do you know the different types of computers? See the next page to get started with the first computer type. The personal computer (PC) defines a computer designed for general use by a single person. While a Mac is a PC, most people relate the term with systems that run the Windowsoperating system. PCs were first known as microcomputersbecause they were a complete computer but built on a smaller scale than the huge systems in use by most businesses.   A PC that is not designed for portability is a desktop computer. The expectation with desktop systems are that you will set the computer up in a permanent location. Most desktops offer more power, storage and versatility for less cost than their portable brethren.   Also called notebooks, laptops are portable computers that integrate the display, keyboard, a pointing device or trackball, processor, memory and hard drive all in a battery-operatedpackage slightly larger than an average hardcover book. Netbooks are ultra-portable computers that are even smaller than traditional laptops. The extreme cost-effectiveness of netbooks (roughly $300 to $500) means they're cheaper than almost any brand-new laptop you'll find at retail outlets. However, netbooks' internal components are less powerful than those in regular laptops. Personal Digital Assistants (PDAs) are tightly integrated computers that often use flash memory instead of a hard drive for storage. These computers usually do not have keyboards but rely on touchscreen technology for user input. PDAs are typically smaller than a paperback novel, very lightweight with a reasonable battery life. A slightly larger and heavier version of the PDA is the handheld computer. Another type of computer is a workstation. A workstation is simply a desktop computer that has a more powerful processor, additional memory and enhanced capabilities for performing a special group of task, such as 3D Graphics orgame development.   A computer that has been optimized to provide services to other computers over a network. Servers usually have powerful processors, lots of memory and large hard drives. The next type of computer can fill an entire room.   In the early days of computing, mainframes were huge computers that could fill an entire room or even a whole floor! As the size of computers has diminished while the power has increased, the term mainframe has fallen out of use in favor ofenterprise server. You'll still hear the term used, particularly in large companies to describe the huge machines processing millions of transactions every day. This type of computer usually costs hundreds of thousands or even millions of dollars. Although some supercomputers are single computer systems, most are composed of multiple high performance computers working in parallel as a single system. The best known supercomputers are built by Cray Supercomputers.   The latest trend in computing is wearable computers. Essentially, common computer applications (e-mail, database, multimedia, calendar/scheduler) are integrated into watches,cell phones, visors and even clothing.
