Modern computing systems' primary building block is computer memory. It keeps track of the information and commands that the processor is currently executing. An address, which identifies the location of the data in memory, is used by programmes to access memory. Physical addresses and virtual addresses are two different ... Read More

Operating systems serve as the foundation for computer systems, enabling users to interact with hardware, run applications, and manage files. Two prominent operating systems in the computing world are UNIX and Windows. UNIX, initially developed in the 1960s, focuses on stability, security, and flexibility, while Windows, introduced by Microsoft in ... Read More

Operating systems play a vital role in managing computer resources and providing a platform for executing programs. Two common types of operating systems are Time Sharing Operating Systems and Multiprogramming Operating Systems. While both aim to improve resource utilization and user experience, they differ in their approach to achieving these ... Read More

In the world of computers and operating systems, there are several terms related to the interaction between users and the underlying system. This includes terminal, console, shell, and command line. While they are often used interchangeably, they have distinct meanings and serve different purposes. Let's explore each term separately to ... Read More

Scheduling algorithms play a crucial role in managing the execution of tasks in operating systems and real-time systems. Two common scheduling approaches are table-driven scheduling and cyclic scheduling. These approaches have distinct characteristics and are suitable for different types of systems and scheduling requirements. What is Table-driven Scheduling? Table-driven scheduling, ... Read More

The concepts of stimulus and response events play a crucial role in understanding how systems and programs interact with each other and with their environment. These terms are often used in the context of event-driven programming, where software components respond to various events triggered by user actions or other system ... Read More

SSTF (Shortest Seek Time First) and LOOK are both disk scheduling algorithms used in operating systems to optimize the order in which disk requests are serviced. While they share the goal of minimizing disk seek time, they employ different strategies to achieve this. SSTF Disk Scheduling Algorithm The Shortest Seek ... Read More

Disk scheduling algorithms are used to determine the order in which disk requests are serviced, aiming to minimize disk head movements and optimize disk access time. Two commonly used disk scheduling algorithms are Shortest Seek Time First (SSTF) and C-LOOK. While both algorithms aim to improve disk performance, they have ... Read More

CPU scheduling algorithms play a crucial role in determining the order in which processes or tasks are executed on a computer's central processing unit (CPU). Two commonly used algorithms for CPU scheduling are Shortest Remaining Job First (SRJF) and Longest Remaining Job First (LRJF). These algorithms prioritize tasks based on ... Read More
