Fundamentals of Computing

I completed several workshops as part of the 4CS015 Fundamentals of Computing module, covering key computing concepts such as command-line navigation, logic circuits, and basic programming using simulators.

In Workshop 5, I worked with an Arithmetic Logic Unit (ALU) in LogSim, performing bitwise operations such as AND, OR, XOR, NAND, NOR, NOT A, ADD, and SUBTRACT. I manually verified each operation using binary calculations. I also built and analyzed a Serial to Parallel Decoder and a Parallel to Serial Converter circuit. Additionally, I designed and implemented an extra circuit to ensure that the input and output indicators matched automatically.

In Workshop 6, I used the Von Neumann Simulator to understand how basic computer architecture executes instructions. I wrote and tested programs to add and subtract numbers, implement loop structures for repeated calculations, and simulate multiplication using repeated addition. I analyzed program execution using instruction sets such as LOADTEMP, ADD, SUB, DISPACC, and HALT, gaining hands-on experience with low-level programming concepts.

In Workshop 7, I worked with the Windows Command Prompt and Linux Terminal to navigate and manipulate file systems. I created and managed directory structures using commands such as md, mkdir, cd, dir, ls, copy, move, and rename. I executed file operations including creating, renaming, and deleting files. To verify directory structures, I used the tree command in Windows and ls -R in Linux.

Through these workshops, I developed a strong understanding of binary operations and their role in ALUs, gained practical experience with circuit simulation and digital logic design, learned how to write and debug simple assembly-like programs, and mastered file system navigation and management across different operating systems.
