Differences Between Procedural Programming and Object-Oriented Programming Aspect Procedural Programming Object-Oriented Programming (OOP) Concept Focuses on functions and procedures to operate on data. Focuses on objects, which encapsulate data and behavior. Structure Programs are structured as a sequence of instructions. Programs are structured around classes and objects. Data Handling Data is usually exposed and shared […]

Role of Operating System Components in Executing Multiple Programs When multiple programs are running simultaneously on a computer, the operating system (OS) manages resources to ensure efficient execution. Different OS components play distinct roles in handling memory, input/output (I/O), processes, files, and user interaction. Here’s how they contribute: 1. Memory Management Function: The memory management

A 2.5 inch diameter disk has 8 platters with each platter having two data recording surfaces, each platter on disk has 4084 tracks, each track has 400 sectors and one sector can store 1 MB of data. Calculate the storage capacity of this disk in Bytes. If this disk has a seek time of 2 milli-seconds and rotates at the speed of 6000 rpm, find the Access time for the disk. Make suitable assumptions, if any.

What is an Instruction? An instruction is a binary-encoded command that tells a computer’s processor what operation to perform. Instructions are fundamental components of a computer program and are executed sequentially (or as per program flow) by the processor to achieve desired computations. Components of an Instruction An instruction typically consists of the following components:
