Although they serve similar purposes, they differ in structure and application.<\/p>\n\n\n\n<p>The OSI model consists of <strong>seven layers<\/strong>: Physical, Data Link, Network, Transport, Session, Presentation, and Application. This model was created by the ISO to standardize networking functions and promote interoperability. Each layer performs a specific task and passes data to adjacent layers, making it ideal for teaching and conceptual understanding.<\/p>\n\n\n\n<p>In contrast, the TCP\/IP model has <strong>four or five layers<\/strong> depending on the interpretation: Network Interface, Internet, Transport, and Application. It was developed by the U.S. Department of Defense based on real protocols used in the ARPANET. Unlike the OSI model, the TCP\/IP model was designed from implementation, making it more practical and widely used today.<\/p>\n\n\n\n<p>While OSI strictly separates concerns across layers, TCP\/IP merges some layers (e.g., OSI\u2019s Session and Presentation layers are part of the Application layer in TCP\/IP).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">\ud83d\udee0 TCP vs IP:<\/h3>\n\n\n\n<p><strong>TCP (Transmission Control Protocol)<\/strong> and <strong>IP (Internet Protocol)<\/strong> are both core protocols of the TCP\/IP model but serve different purposes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>IP<\/strong> is responsible for addressing and routing data packets across networks. It ensures that data reaches the correct destination using IP addresses, but it does not guarantee delivery.<\/li>\n\n\n\n<li><strong>TCP<\/strong>, on the other hand, provides <strong>reliable<\/strong>, <strong>connection-oriented<\/strong> communication. It ensures that packets are delivered in order, without loss or duplication, by using acknowledgments, retransmissions, and flow control.<\/li>\n<\/ul>\n\n\n\n<p>In short: <strong>IP handles delivery<\/strong>, while <strong>TCP ensures reliability<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What are the major differences between the OSI model and the TCP\/IP model?
