There are various meanings of proxy depending on what context it is used in. This post is to clarify the uses and the definitions of "proxy". Proxy Server: This is an intermediary server separating end users from the websites they browse. Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, needs, or company policy. Reverse Proxy: This is a typ..

The data transmitted through UDP is organized into units called datagrams or frames. The UDP frame format consists of four primary fields, each of which is 2 bytes (16 bits) long. These fields are as follows: Source Port (16 bits): This field specifies the source port number, which identifies the sending application on the source device. It helps the recipient device know which application to pa..

Reliable communication and unreliable communication are two distinct approaches to data transmission, each with their own advantages and trade-offs: Reliable Communication: a. Ensures data is transmitted accurately and completely from the sender to the receiver. b. Employs error checking, retransmission of lost packets, and acknowledgment mechanisms to guarantee successful data delivery. c. Main..

Connectionless Protocol: Unlike TCP, UDP is a connectionless protocol, meaning it does not establish a persistent connection between devices before transmitting data, making it faster and more lightweight. No Error Recovery: UDP does not provide error recovery or retransmission of lost packets. This makes it suitable for applications where low latency and real-time data delivery are more importa..

TCP (Transmission Control Protocol) and SCTP (Stream Control Transmission Protocol) are both transport layer protocols used in computer networks to establish reliable connections and transfer data between devices. TCP: Connection-oriented: Before data transfer, a connection must be established between the sender and receiver. Reliable: It ensures data is delivered correctly by using acknowledgem..

Connectionless and connection-oriented are two communication methods used in networking and data transmission. They refer to how data is sent between devices or systems, and each has its own set of advantages and disadvantages. Connection establishment: Connectionless: In a connectionless communication, no dedicated path or connection is established between the sender and receiver before data tr..
