Close to 100%. ATMs and Cellular Phones are computers. Input, Processing, Storage, Output. If a machine does that, it is a computer.
Keyboard and touchpad are input devices, but they have output aspects, such as the CAPS LOCK light indicator on a standard PC keyboard. Typical output devices on a standard computer include the video adapter with the monitor or display, the sound adapter with loudspeakers, the printer. Many other devices are bidirectional in nature (hard disks, memory cards, all types of network or bus connectors) and can thus be counted among the output devices.
Perhaps it would be better for you to research what "output device" means. If you need to output something, you need an output device. There is simply no alternative to which you can compare it.
Modern computers were in experimental use in the 40's and 50's. During the 60's, computers were more common but only among governments or computer research companies.
An operating system coordinates the activities of computer hardware
The five categories of computer are:Super ComputersMainframe ComputersWorkstation computerMinicomputerMicro ComputerSupercomputer: A computer which, among existing general-purpose computers at any given time, is often in several senses: highest computation rate, largest memory, or highest cost.Mainframe Computers: A large digital computer serving 100-400 users and occupying a special air-conditioned room.Workstation computers: This computer has more computing capacity in its CPU than a typical personal computer.Scientists and engineers are the main users of workstations, although people who process graphics find a workstation necessary, since the processors can handle the huge amounts of data associated with graphic files.Minicomputer: A mid-sized computer, usually fitting within a single cabinet about the size of a refrigerator, that has less memory than a mainframe.Micro Computer: A personal computer
A fully loaded computer means that the computer has loads of memory, a durable processor and plenty of useful features and applications that you wouldn't get with a regular computer. Fully loaded computers are particularly popular among gamers and business people.
A computer network, often simply referred to as a network, is a collection of computers and devices interconnected by communications channels that facilitate communications among users and allows users to share resources. Networks may be classified according to a wide variety of characteristics. A computer network allows sharing of resources and information among interconnected devices.
The OS allows the computer programs to function correctly by allowing them to communicate with other programs and the computer. Windows is an OS, which bring all the programs together and allows the user to access them. The operating system manages the use of the hardware among the various application programs for the various users and provides the user a relatively simple machine to use.
The use of computers in enterprises and industries is fundamental for everything. Medium and large enterprises have a network of computers. However, the appropriate configuration and weekly maintenance of the computer's network in a enterprise is the basis for the best performance. Computers allow that the flowing of tasks among different departments run efficiently, thus providing more efficiency which means progress and higher salaries to the employees.

it is nothing but only the different arrivals or development of computers..... that is in older days the computer is an instrument which is very expensive & even large in size ....... but now a days it is much more simpler ...... thus evalution of computer is a greater achivement among the scientist......
