Understanding HTTP, Socket, TCP, and UDP Concepts The five-layer network model outlines the communication process between servers. HTTP implements various functions by adhering to speciifc protocol specifications. Socket acts as an abstraction layer, allowing direct interaction with TCP and UDP without dealing with HTTP protocols. TCP (Transmis ...

After successfully implementing user authentication, the next step toward enabling real-time messaging is retrieving a list of online contacts. Without this list, users have no one to commnuicate with. Upon successful login, the server spawns a dedicated thread to manage ongoing communication with that client, allowing it to handle additional l ...

TCP and UDP Protocols TCP (Transmission Control Protocol) is a connection-oriented transport layer protocol that ensures reliable communication. It guarantees data integrity, preventing loss, disorder, duplication, or corruption during transmission. Typical use cases for TCP include: User authentication and session management in applications l ...

Loop statements are ubiquitous in programming, responsible for repeating code execution. In .NET, we commonly use while, do-while, and for loops. While these seem like simple flow control tools at a micro level, at a macro level within complex modules or systems, the loop becomes the "power source" of the application. We refer to thes ...

Socket vs HTTP: Core Networking Differences TCP Connection A TCP connection forms the foundation of reliable bidirectional communication. It relies on a three-way handshake (SYN, SYN-ACK, ACK) to establish a session. While game developers rarely need to implement or debug this layer manually, awareness of its role in ensuring packet delivery an ...

DNS and Domain Resolution When a user initiates a request via a URL, the first step is resolving the domain name to an IP address via the Domain Name System (DNS). DNS operates at the application layer, translating human-readable hostnames into machine-readable IP addresses. While direct IP access is possible, domain names provide a layer of ab ...

Domain Name System (DNS) Resolution The Domain Name System (DNS) provides a mechanism for translating human-readable domain names into numerical IP addresses and vice-versa. A domain name acts as a substitute, or alias, for an IP address. DNS servers are responsible for this translation. When you access a website, your computer's default DNS se ...

Building upon traditional HTTP listener architectures, this section explores a highly optimized, directive-driven alternative within the DSAPI framework. This approach reduces development overhead by treating network exchanges as direct, short-string commands rather than full request-response cycles. For example, transmitting a specific keyword ...

Network Protocol Models OSI Reference Model Application Layer: Actual data being transmitted Presentation Layer: Data encryption/decryption Session Layer: Session establishment and connection management Transport Layer: Data transmission methods (datagram, stream) Network Layer: Data routing between networks (IP addressing ...

Computer Network Fundamentals A computer network is a system that interconnects autonomous computing devices through transmission media, communication facilities, and standardized protocols to enable resource sharing and data exchange. Network programming involves writing software that allows two or more networked devices to transfer data betwe ...
