General purpose computers and special purpose computers are two classifications of computers according to use. Not surprisingly, most computers are considered general purpose machines, since they are built for such a wide range of processing capability, explain byte-notes.com computer experts.Know More
Various tasks can be completed on a general purpose computer by utilizing a variety of software. Tasks include controlling security systems, making calculations, manipulating facts in a database, writing and editing. Examples of such electronics include desktops, laptops, notebooks and smart phones. Such devices can store a variety of programs internally, though large amounts may result in compromises of speed and efficiency -depending on the amount of internal storage available.
Special purpose computers are task-specific and are generally used for one particular purpose in performing a single task again and again. Examples of this type of computer include traffic light control systems, navigational systems, digital watches and robot helicopters. Special purpose computers are built with a function of design to address a specific problem instead of utilizing stored programs. Since they perform a single function while using less memory and information, such computers often function faster than their general purpose counterparts. However, they are also less versatile and unable to perform a multitude of operations, states byte-notes.com.Learn more about Computers & Hardware
Random access memory, or RAM, is a volatile yet fast type of memory used in computers. RAM is more expensive to incorporate, which is why there is usually far more direct access storage in a computer, such as hard drives.Full Answer >

The four components that all computers have in common are input, output, storage and processing, according to Intel's educational website. Input devices accept information into a computer, while output displays the information in a readable format. Storage involves items like discs or memory sticks that save data and the processor executes computer programming instructions.Full Answer >
Old computers are safely disposed of by wiping the hard drive and donating or recycling the unit. Using a responsible electronics recycler keeps the computer and its potentially dangerous components out of the landfill. If the computer still works, donating it to a charity is another option.Full Answer >
