history of computers
*The first computers were people! That is, electronic computers (and the earlier mechanical computers) were given this name because they performed the work that had previously been assigned to people. "Computer" was originally a job title: it was used to describe those human beings (predominantly women) whose job it was to perform the repetitive calculations required to compute such things as navigational tables, tide charts, and planetary positions for astronomical almanacs. Imagine you had a job where hour after hour, day after day, you were to do nothing but compute multiplications. Boredom would quickly set in, leading to carelessness, leading to mistakes. And even on your best days you wouldn't be producing answers very fast. Therefore, inventors have been searching for hundreds of years for a way to mechanize (that is, find a mechanism that can perform) this task.
*The development of the modern day computer was the result of advances in technologies and man's need to quantify. Papyrus helped early man to record language and numbers. The abacus was one of the first counting machines..
Some of the earlier mechanical counting machines lacked the technology to make the design work. For instance, some had parts made of wood prior to metal manipulation and manufacturing. Imagine the wear on wooden gears. This history of computers site includes the names of early pioneers of math and computing and links to related sites about the History of Computers, for further study. This site would be a good Web adjunct to accompany any book on the History of Computers or Introduction to Computers. The "H" Section includes a link to the History of the Web Beginning at CERN which includes Bibliography and Related Links. Hitmill.com strives to always include related links for a broader educational experience. The material was originally divided into Part 1 & Part 2
different types of computer
The types of computers range from the Hybrid to the Analog types. The computers you come across in the daily course of your day range from laptops, palmtops and towers, to desktop computers, to name a few. But the very word “computers” reminds one of the desktop computers used in offices or homes. Different categories of computes have been devised in keeping with our varied needs.
The Types Of Computers: Analog and Hybrid (classification based on operational principle)
Analog Computers: The analog computer is almost an extinct type of computer these days. It is different from a digital computer in respect that it can perform numerous mathematical operations simultaneously. It is also unique in terms of operation as it utilizes continuous variables for the purpose of mathematical computation. It utilizes mechanical, hydraulic, or electrical energy or operation.
Hybrid computers: These types of computers are, as the name suggests, a combination of both Analog and Digital computers. The Digital computers which work on the principle of binary digit system of “0” and “1” can give very precise results. But the problem is that they are too slow and incapable of large scale mathematical operation. In the hybrid types of computers the Digital counterparts convert the analog signals to perform Robotics and Process control.
Apart from this, computers are also categorized on the basis of physical structures and the purpose of their use. Based on Capacity, speed and reliability they can be divided into three categories of computers:
1. The Mainframe Computer – These are computers used by large organizations like meteorological surveys and statistical institutes for performing bulk mathematical computations. They are core computers which are used for desktop functions of over one hundred people simultaneously.
2. The Microcomputer – These are the most frequently used computers better known by the name of “Personal computers”. This is the type of computer meant for public use. Other than Desktop Computer the choice ranges as follows:
Personal Digital Computer
Tablet PC
Towers
Work Stations
Laptops
Hand Held Computer
3. The Mini computer – Mini computers like the mainframe computers are used by business organization. The difference being that it can support the simultaneous working of up to 100 users and is usually maintained in business organizations for the maintenance of accounts and finances.
Yet another category of computer is the Super Computers. It is somewhat similar to mainframe computers and is used in economic forecasts and engineering designs. Today life without computers is inconceivable. Usage of different types of computers has made life both smooth and fast paced.
kinds of computer
A computer is a machine that manipulates data according to a list of instructions.
There are a lot of terms can be found over the internet related to computer. All type of computer have processor, Memory, keyboard, mouse and screen to display output. But their is a significant difference how people or organizations use computes for their usage. We can divide all type of computers to 10 categories.
Personal Computer (PC) : A personal computer (PC) is a computer whose original sales price, size, and capabilities make it useful for individuals, and intended to be operated directly by an end user, with no intervening computer operator. People generally relate this term with Microsoft’s Windows Operating system. Personal computers generally run on Windows, Mac or some version of Linux operating system.
Desktop: Desktop computer is just another version of Personal Computer intended for regular use from a single use. A computer that can be fit on a desk can also be called as desktop. Desktop computers comes in different form vertical tower cases to small form factor. For more information please visit desktop at Lenovo.com
Laptop: Laptop computer , Laptop or Notebook all are same. Laptop’s are generally small mobile computers run on a single main battery or from an external power supply that will served as to run the laptop as well as charge the battery. Laptop contains all the components of computer but all these are optimized for mobile users.
Personal Digital Assistants(PDAs): A personal digital assistant (PDA) is a handheld computer, also known as small or palmtop computers. Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones (smartphones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs). Many PDAs employ touch screen technology.
Workstation: A computer that has a more power resources like Processing Power, Memory and additional capabilities to perform special task refers to as workstation. Workstations are often optimized for displaying and manipulating complex data such as 3D mechanical design, engineering simulation results such as for computational fluid dynamics, animation and rendering of images, and mathematical plots.
Server: A server computer is a computer dedicated to running a server application. A server application is a computer program that accepts connections in order to service requests by sending back responses. Examples of server applications include web servers, e-mail servers, database servers, and file servers.
Mainframe: In early days of computing Mainframes are big computers that can fill the entire room or entire floor. Mainframes are mainly used by large organizations for critical applications, such as consumer statistics, ERP, and financial transaction processing.
Minicomputer: Minicomputers are lie between the Mainframe computer and small Personal Computers. Minicomputers also refereed to Mid-Range Servers. Minicomputers are more powerful but still compatible version of a personal computer.
Supercomputer: A computer which, among existing general-purpose computers at any given time, is superlative, often in several senses: highest computation rate, largest memory, or highest cost. Predominantly, the term refers to the fastest “number crunchers,” that is, machines designed to perform numerical calculations at the highest speed that the latest electronic device technology and the state of the art of computer architecture allow.
Wearable : Wearable computers are computers that are worn on the body. They have been applied to areas such as behavioral modeling, health monitoring systems, information technologies and media development. Government organizations, military, and health professionals have all incorporated wearable computers into their daily operations. Wearable computers are especially useful for applications that require computational support while the user’s hands, voice, eyes or attention are actively engaged with the physical environment.
