Class 3 (28 Sept 2024)
a) Class Summary:
-
Abstraction, Algorithms, and Pseudocode: Students learned how to apply abstraction in real-world scenarios like flight booking, explored algorithms using flowcharts, and understood the role of pseudocode for simplifying programming logic. Pseudocode was presented as a tool to design algorithms without needing specific programming languages.
-
Pattern Recognition and Decomposition: The class emphasized recognizing patterns and decomposing problems in programming. These concepts were linked to software development, where similar tasks can be reused across different applications, making programming more efficient and manageable.
-
Binary and Bitwise Operations: Students were introduced to binary shifts, where shifting bits left or right corresponds to multiplying or dividing by 2. Bitwise operations like AND, OR, and XOR were discussed, along with their applications in programming tasks such as bit masking and representing negative numbers in binary.
-
Parallel and Concurrent Processing: The class covered parallel and concurrent processing, explaining how tasks are managed in multi-processor systems to enhance speed and efficiency. The differences between parallel processing (multiple tasks at once) and concurrent processing (one processor handling multiple tasks in sequence) were highlighted.
