In JavaScript, there isn't a distinct data structure referred to as an "associative array." Instead, developers often use objects to achieve similar functionality. Key-value pairs Objects in JavaScript are collections of key-value pairs, where the keys (also called property names) are strings ...

Web development: Hash tables (A hash table is a data structure that implements an associative array abstract data type, where data is stored in key-value pairs, and the keys are mapped to indices using a hash function for efficient retrieval and storage) are utilized for effective caching and...
Yes, lookup functionality is commonly implemented in programming languages. Most programming languages offer built-in data structures or libraries that support efficient lookup operations. For example, dictionaries in Python, hash maps in Java, and associative arrays in PHP provide lookup capabilities by...
This term is also known as associative array, map, table, and in query processing an index or index table. Techopedia Explains Dictionary Operations, typically used with a dictionary, are: Insert: Adding a new key and value pair Reassign: Adding a new value to an existing key Remove/Delete...

A(B+C)=AB+AC. This property applies to subtraction as well. A(B–C)=AB–AC Here, the multiplier A is ‘distributed’ in order to multiply it with B and C separately. (A, B, and C are any real numbers.) Let’s visualize the distributive property using multiplication arrays!

Suppose that a 16M X 16 main memory is built using 512K X 8 RAM chips and memory is word addressable. a) How many RAM chips are necessary? b) How many RAM chips are needed for each memory word? c) Ho Explain the operations of: i) Cache Memory ii) Associative Memory iii) Virtual...
one must also modify the subsequent block. However, changing that block also changes its hash value, necessitating changes to the next block, and so on. Repeating this process for all linked blocks is practically impossible, especially given the vast number of blocks in blockchains like Ethereum...
