11. Punch Card Technology made by International Business Machine (IBM) made from stiff lightweight cardboard, punch cards were used by data processing machines to record information.
12. Electronic Numerical Integrator Analyzer and Computer(ENIAC) designed by John Presper and John William Mauchly. it was built by the US Army in 1945 to calculate the trajectory of ballistic missiles, at a cost of almost $500,000.
14. STORAGE Refers to the ability of computer to store and retain data in their memories Types of Memory Volatile memory - refers to computer memory that requires electric power to maintain stored data. ex. Random-access memory (RAM) 2. Non-volatile memory – retains data even if electric is cut off. ex. hard disks, floppy disks, and CD ROMs
15. Process Data processing - Is defined as the conversion of data from one format to another DATA – refers to a collection of numbers and characters which the computer understands. MICROPROCESSOR – brain of the computer controls the flow of data – Central processing unit (CPU)
16. Method of Processing Parallel Processing - harnesses the power multiple processors in one computing entity to perform a single task. Distributed Processing - is used to bind multiple computing entity so that they become a single centralized unit focused on common task or goal.
30. Mouse lets you feeds instructions to the computer by simply pointing and clicking in a graphical environment
31. System Case box that house the CPU. It has expansion slots contains spare drive bays, and allows space to work inside for attachments to the system unit.
32. Motherboard main circuit board in the computer. Its chipset must support the kind of hardware you want with your system.
38. Video/Graphics Card most graphics cards today have at least 32 MB. Using a card that has less might cause problems with the computer you are building because many programs that use heavy graphics will not work.
39. Sound Card converts data into sound to be sent to speakers or converts sounds to digital formats.
