This article compiles a complete set of 30 network‑foundation mind maps, covering everything from the TCP/IP protocol stack and addressing to routing protocols, VLANs, IPv6, and command‑line basics, allowing readers to visually grasp and later recreate core networking concepts.
Using a familiar chat example, this article walks through the OSI seven‑layer model, illustrating each layer’s role—from the application’s HTTP request to the physical bitstream—through analogies with parcel delivery, complete with data format transformations and visual diagrams.
This article compiles 38 detailed mind maps that systematically cover core computer networking concepts—from basic data communication and transmission media to advanced protocols like GRE and IPSec VPN—helping readers visualize, retain, and apply key networking knowledge efficiently.
David L. Mills, the visionary behind the Network Time Protocol and a key architect of the early Internet, passed away at 85, leaving a legacy that spans groundbreaking synchronization technology, influential RFCs, and a playful spirit that inspired generations of developers.
This interview chronicles Liu Hongqiang’s journey from Tsinghua and Yale to becoming a leading Alibaba Cloud network researcher, highlighting his award‑winning papers, groundbreaking protocols such as HPCC, ACL automation, NFC+, and XLINK, and his philosophy of balanced, impact‑driven innovation.
This article explains the concept of communication networks, traces the evolution of computer networking, defines LAN, MAN, and WAN, describes common topologies, compares circuit and packet switching, outlines performance metrics, introduces the OSI and TCP/IP models, and details the functions and protocols of each network layer.
This article provides a comprehensive introduction to computer networking fundamentals, covering the historical evolution of the Internet, network classifications, topologies, performance metrics, OSI and TCP/IP models, physical and data link layers, IP addressing, routing protocols, transport mechanisms, and key application-layer protocols such as HTTP, FTP, DNS, and DHCP.
This article explains the fundamentals of network communication protocols, describing the OSI seven‑layer model, its simplification to the TCP/IP four‑layer architecture, and detailing the functions of each layer—from the network interface up to the application layer—using clear analogies and packet examples.
This article explains what network protocols are, why layered designs simplify communication, and compares the OSI seven‑layer model with the TCP/IP reference model, detailing each layer’s functions, typical protocols, and practical examples.
