Characteristic of computer

                       Characteristic of computer means Speed, Accuracy, Storage capacity, Versatility, Diligence, Re ability and Indescribable benefits etc.
                        Computer preforms complex calculation at a very high speed this speed varies from a few microsecond to nanoseconds. Computer are very accurate. Its gives 100% actual output (result), if the user provides correct input and instruction. If any mistakes occurs in any calculation they are due to manual error but not of computer. The computer have the ability to store a huge amount of data in its secondary devices like floppy disk and hard disk. The stored information also can retrieve immediately. Computer are being used in different field to performs the various tasks. It has capability to performs various tasks. Computer is capable of performing the required task continuously with the same speed ,accuracy and efficiency with out any error. Its output is generally very reliable, if the input data and instruction is correct. Many orginization and companies use for indescribable benefits.     

Computer

                    The terms "computer" is derived from the Latin word "computare" this means to calculate. Now a days we define computer as an electronic device, which takes raw data as input from the user and process these data under the control of instructions and gives the result (output). If the output is useful in future then also we can save it and use it and use it later.
                      The working principal of computer us classified in to three ways firstly Input secondly Process and thirdly Output cycle. In input we have to put data from the different device of computer such as Mouse, Keyboard, Scanner, Digital camera, Web camera, Joysticks, Lights pen, Touch pen, BCR/OCR/
MICR etc.And after input data from this device secondly there must be process it is unseen it used to work from the device CPU, ALU+CU. And lastly the result or out put must be seen. It can be distracted/achieve from the device monitor, printer, plotter. the working way of computer is like our digestive system.
