String Operations and Queue Data Structures Explained
String Storage and Memory Representation
A string is a collection of characters stored together in memory. Strings are used to store names, words, sentences, and other text data in computer systems. In programming languages like C, a string is stored as an array of characters and ends with a special null character '\0'.
Example of String: char name[] = "ROHIT";
In memory, the string is stored as:
| R | O | H | I | T | \0 |
Here, \0 represents the end of the string.

1. Elementary Data Organization
Elementary data organization refers to the basic method of arranging and managing data in a computer system. Data is organized in the form of characters, fields, records, files, and databases. A character is the smallest unit of data, while a field is a group of related characters. Multiple fields form a record, and records together create a file. Proper data organization helps in storing, accessing, and processing information efficiently. It improves

Dataflow Architectures in Machine Learning
Why use dataflow architecture for ML?
Dataflow architectures eliminate the need for a program counter, executing instructions based solely on input data availability. This minimizes the massive energy and latency costs associated with fetching data from main memory (DRAM) in traditional von Neumann architectures, making it highly efficient for Machine Learning workloads.
