Computer fundamentals  Objective: Computer Advantages History Classification Components Computer "Computer is an electro-mechanical device, which takes the Input  from the user and, after processing it, gives the Output to user" Input: Input means the commands, or instructions, which a user give to the computer to know the solution. Processing:  The computer doesn't know our language. It only knows the Binary Language the is 0110011001100.Computer first converts our language to understand and after that again converts the binary data to the user language so that the user can understand the result. Output:  Output means the result given by computer against a specific input. Suppose a user wants to know the result of 2+2 In the case, 2+2 is the input After taking this input, computer converts the 2+2 to binary language to understand the input, after that creates the result in binary and converts the result into the user language and then shows the result in monitor whi...

  First Generation: Vacuum Tubes (1940–1956) The first  generation of computer     systems used   vacuum tubes for circuitry and   magnetic drums  for main   memory , and they were often enormous, taking up entire rooms. These computers were very    expensive to operate, and in addition to using a great deal of electricity, the first computers generated a lot of heat, which was often the cause of malfunctions. The maximum internal storage capacity was 20,000 characters.  Second Generation: Transistors (1956–1963) The world would see   transistors replace vacuum tubes in the second generation of computer. The transistor was invented at Bell Labs in 1947 but did not see widespread use in computers until the late 1950s. This generation of computers also included hardware advances like magnetic core memory, magnetic tape, and the magnetic disk. Third Generation: Integrated Circuits (1964–1971) The development of the integrated...
