This episode focuses on the three major computer applications: data processing, control, and design. Hertzler navigates the maze of software, hardware and modern computing. It begins with Hertzler's futile attempts to balance his checkbook by hand using a calculator. Perhaps a computer presents an alternative to this form of accounting? He then examines the rise of computers beginning with innovations put forth by Blaise Pascal and Charles Babbage’s analytical engine. Hertzler explores the five main components of computing machines Babbage originally envisioned; memory, output, control and arithmetic. He shows how modern computing operations still trace the same path. He defines the difference between hardware and software, the role of memory components such as magnetic tape and disk packs, input devices including keyboards and output devices such as printers and video screens. He also highlights the central processing unit; the CPU, and the arithmetic logic unit; or the ALU. These technological innovations paved the way for computer software such as Google Sheets or Microsoft Excel. The final section shows a demonstration using a program designed to calculate basketball team statistics. Much of the equipment used in the film was manufactured by the tech giant IBM. 00:00 Hertzler begins with scratch and paper to balance his checkbook (1:11). Challenges of human error plummet him into frustration. He turns back to the late 17th century as the adding machine was dreamed up (2:13) exploring works by Blaise Pascal showing his photograph (2:17) and a replica of Blasie’s adding machine (2:25). Hertzler also explains variances in day to day use of arithmetic from the 17th century to modern day (2:47). He introduces Charles Babbage (3:39) and a modern reconstruction of Babbage’s 1883 invention (4:00); the analytical engine (4:35). Modern computer cards (4:54) and compared to metal cards (4:57) used in Babbage’s machine. He traces the five main components of the computer including input (5:09), control (5:10), arithmetic/logic (5:13), memory (5:29) and output (5:45). Hertzler stands amid a large mainframe computing center in order to explore the five main components (6:04). He begins with the keyboard (6:15); an input component. Instruction entered into the computer via input methods are interpreted by the control unit (7:07). He motions to an IBM 4300 (7:24) a part of the arithmetic logic component. Mass storage devices such as magnetic tape (7:58) and magnetic disk packs (8:31) are part of the memory component. The version shown is an IBM. Output components such as printers (8:54) and video screens (9:05) enable removal of information from the machine. He returns to the IBM 4300 in order to explain its circuits and their location (9:16). Hertzler dissects a Tandy / Radio Shack TRS-80 type computer keyboard revealing the circuit board and it’s five main components (9:50). He relays the difference between hardware and software (10:32). In a final demonstration, Hertzler explores an application software program designed to track a basketball team player’s totals in order to calculate percentages and averages over the season (11:09). He notes in this application the software instructions are numbered on the display screen (11:42). He delivers an in depth instruction on how the software operates pausing at a stage where the computer absorbs the information (11:50). He ‘runs’ he program (12:01) by typing the instruction ‘run’. He shows how the memory portion of the five main components operates; the system software is able to recognize a misspelling in his instruction. Hertzler distinguishes application software from system software. In a second attempt, he runs the program (13:18) and the display screen relays specific statistics. Credits. Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
