Operating System History : The first operating system used for real work was GM-NAA I/O, produced in 1956 by General Motors’ Research division for its IBM 704. Introduction : All computers need some sort of hardware platform to run the software; these platforms are called Operating System (OS). Definition : An operating Read more…

Introduction of Socket The concept of Socket began with the ARPANET in 1971. The term network socket is most commonly used in the context of the Internet protocol suite and is therefore often also called Internet socket. The term network socket is analogous to an electrical device’s female connector. The concept Read more…
History The concept of Client-server model was started from 1960s. ARPANET is considered as the first client-server model. Introduction Client server architecture is also known as “Client-Server Model”. It works according to a request and response method. Definition Client-Server architecture is a system where one computer (or more) is/are acting Read more…

Introduction The Application Layer in the TCP/IP model is crucial for enabling network communication between software applications. Definition The application layer in the TCP/IP model is the topmost layer and is responsible for facilitating communication between network applications. Features It provides services to the application software running on a computer. It provides various protocols Read more…
Introduction The Transport Layer in the TCP/IP model is vital for ensuring the reliable delivery of data between applications running on different hosts. TCP provides a robust, connection-oriented service that guarantees the delivery and order of data, while UDP offers a lightweight, connectionless service for applications where speed and efficiency Read more…
