What is memory hierarchy?
The memory hierarchy is a pyramid-like structure that organizes different types of computer memory based on their speed, cost, and capacity. It arranges storage devices from fastest to slowest, creating an efficient balance between performance and cost in computer systems. Memory Hierarchy Structure Memory Hierarchy Pyramid CPU Registers Cache Memory Main Memory (RAM) Secondary Storage Tertiary Storage Fastest, Most Expensive Very Fast, ...
Read MoreWhat is computer architecture?
Computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. It defines how a system performs operations and executes instructions, serving as the blueprint for building and understanding computers. Sub-divisions of Computer Architecture Computer architecture can be divided into three main categories − Instruction Set Architecture (ISA) − Defines the interface between software and hardware. It specifies the instructions a processor can execute, data types, registers, memory addressing modes, and interrupt handling. The ISA acts as a contract between software programmers and hardware designers. Microarchitecture − Describes ...
Read MoreWhat are process states?
A process is a program in execution that consists of more than just program code (text section). This concept works under all operating systems because every task performed by the operating system requires a process to execute. A process executes by changing its state over time. The state of a process is defined by the current activity and status of that process within the system. Types of Process States Each process may be in any one of the following five states − New − The process is being created and initialized by the operating system. ...
Read MoreHow should I store data into my Mysql database, what type should I assign to a column storing salt values?
A salt is a random value added to passwords before hashing to prevent rainbow table attacks and ensure that identical passwords produce different hash values. When storing salts in a MySQL database, choosing the appropriate data type is crucial for security and performance. Recommended Data Types for Salt Storage The most suitable MySQL data types for storing salt values are: BINARY(16) − Fixed-length binary data, ideal for 128-bit salts generated by cryptographic functions. VARBINARY(32) − Variable-length binary data, suitable for salts of varying lengths up to 256 bits. CHAR(32) − Fixed-length ...
Read MoreWhat is Web Architecture?
Web architecture refers to the structural framework and design principles that define how web applications are organized, implemented, and deployed. It encompasses the technologies, protocols, and components that work together to deliver web content and functionality to users across the internet. At its core, web architecture involves the strategic arrangement of client-side and server-side components, data flow patterns, and communication protocols such as HTTP/HTTPS. It determines how users interact with web applications, how data is processed and stored, and how different system components communicate with each other. Web Architecture Overview ...
Read MoreTypes of Authentication Protocols
Authentication protocols are methods or procedures used to verify the identity of a user, device, or system. These protocols are designed to ensure that only authorized users or devices can access protected resources, preventing unauthorized access or tampering. Authentication Process Flow User Requests Access Auth Server Verifies Identity Resource Grants Access ...
Read MoreWhat is machine learning? How it is helpful for decision making?
Technology has served as a catalyst in the development of our civilization, with humans and machines coexisting to create seamless connectivity and ease of access. In this technological landscape, Artificial Intelligence (AI) deserves special mention, and Machine Learning stands as its integral component. Machine Learning is a concept where computers learn autonomously without explicit programming to perform specific tasks. It empowers computers to identify patterns, make predictions, and improve performance through experience. Machine Learning can be broadly categorized into supervised learning, unsupervised learning, and semi-supervised learning. Machine Learning in Decision Making ...
