SS 1 Data Processing

Super Computer Supercomputers, also known as MONSTER, stand as the pinnacle of computing power, boasting unparalleled size, speed, and cost. Valued at several million dollars, these machines operate at speeds ranging from 600 million to 900 million instructions per second (MIP). Supercomputers find utility in various scientific endeavours, including weather forecasting and exploration, handling complex […]

Digital computer: The most prevalent type of computer today, it quantifies physical quantities through counting. Examples include calculators, digital wristwatches, and digital fuel dispensers.   Analogue computer: Utilized for measuring and processing continuous data such as speed, temperature, and heartbeat. Examples include speedometers and thermometers.   Hybrid computer: This computer type integrates features from both

First Generation (1951-1958): The initial phase of computer development marked the era of vacuum tubes. These computers were colossal and operated at a sluggish pace. They primarily utilized machine language, and their internal storage capacity was limited, characterized by small internal storage.   Second Generation (1959-1964): Advancements led to the incorporation of transistors, reducing heat

Early Computing Generations The initial phase of computing machines, distinct from mechanical counterparts, emerged around 1945. An example from this era is UNIVAC.   First-Generation Computers: Use of vacuum tubes. Large and expensive dimensions. Bulky design. Low retentive memory. Significant heat generation.   Second Generation Replacing vacuum tubes, second-generation computers employed discrete transistors. Though with

In this lesson, you will explore the concepts of data and information, discern the distinctions between them, and differentiate manual from electronic data processing.   Meaning of Data: Data refers to fundamental facts that can be input into a processing system, where computations, comparisons, and general data manipulation occur. This processing can be carried out
