  • SFTP (Secure File Transfer Protocol)

    SFTP (Secure File Transfer Protocol) is an advanced network protocol designed to provide secure file transfer over a reliable data stream, ensuring both confidentiality and integrity during data transmission. Unlike FTP (File Transfer Protocol), which transmits data in plain text, SFTP operates over a secure SSH (Secure Shell) connection, protecting the data from interception and…

  • Public key encryption (PKE)

    Public key encryption (PKE) is a cryptographic method that uses two keys: a public key, shared openly, and a private key, kept secret by the owner. Unlike symmetric encryption, which relies on a single key for both encryption and decryption, PKE ensures secure communication between parties without sharing secret keys in advance. This model underpins…

  • Session Layer : OSI Model

    The Session Layer (Layer 5 of the OSI model) orchestrates and manages dialogs between devices, ensuring structured and organized communication. It acts as a controller of sessions, focusing on establishing, maintaining, and terminating connections across networked systems. This layer abstracts lower-level complexities while delivering session-related functionalities to applications, such as synchronization, dialog control, and checkpointing.…

  • Transport Layer : OSI Model

    The Transport Layer (Layer 4 of the OSI model) is the cornerstone of reliable communication in networking, bridging the gap between high-level application requirements and low-level data transmission. It ensures accurate delivery of data between devices, providing error detection, correction, flow control, and session multiplexing. Key Responsibilities of the Transport Layer 1. Segmentation and ReassemblyData…

  • Network Layer : OSI Model

    The Network Layer (Layer 3 of the OSI model) is a pivotal component in computer networking, responsible for end-to-end delivery of data across interconnected networks. It abstracts the complexities of routing and addressing, ensuring data packets traverse multiple networks efficiently and reliably. Core Responsibilities 1. Logical AddressingThe layer assigns unique logical addresses (IP addresses) to…

  • HTML (PWA) : Web Manifest

    A Web App Manifest is a JSON file that defines the metadata required to make a web application installable and resemble native mobile or desktop applications. It is a core component of Progressive Web Apps (PWAs) and plays a pivotal role in enhancing user experience by enabling features like a custom home screen icon, a…

  • HTML Global Attributes and Event Attributes for Web Interactivity

    In HTML, global attributes and global event attributes are fundamental because they can be applied to nearly all HTML elements. They provide extra flexibility in customizing and controlling elements, and understanding them can enhance both accessibility and interactivity on a webpage. Global Attributes in HTML Global attributes are attributes you can use on any HTML…
