Finally, some protocols, such asUser Datagram Protocoland RC-5, use neither ACK nor NAK. Instead, they perform blind transmission and may transmit the same message multiple times hoping that at least one copy is transmitted correctly and without error to the receiving station. Three-way handshake...
When discussing what is SNMP in computer network science, we need to take into consideration Protocol Data Units (PDUs). When commands or messages are sent between an SMNP manager and an SNMP agent, they are transported via User Datagram Protocol (UDP) or Transmission Control Protocol/Internet ...
UDP uses IP to get a datagram from one computer to another. UDP gathers data in a UDP packet and adds its own header information to the packet. This data consists of the source and destination ports on which to communicate, the packet length and a checksum. After UDP packets encapsulate i...
How does SNMP work in Internet Protocol networks? Generally speaking, the SNMP protocol employs the User Datagram Protocol (UDP) as its underlying transport layer protocol. UDP is a wireless protocol similar to TCP, but it does not provide error-checking and recovery services. Instead, UDP contin...
For example, HTTP servers commonly use TCP port 80. When a port accepts aconnection, it can be assumed that the commonly bound program is running. Usage The reason for having ports is that virtually all modern computers support multitasking. Thus, on a typical computer, there will be multiple...
An alternative to TCP in networking is the User Datagram Protocol (UDP), which is used to establish low-latency connections between applications and decrease transmissions time. TCP can be an expensive network tool as it includes absent or corrupted packets and protects data delivery with controls ...
(i). What should be the flag value to indicate the last fragment? (ii). If the value in protocol field is 17, which transport layer protocol is used? (iii). Which field of datagram helps to check rea 1. (i). What should be the flag value to indicate the last fragment? (ii). ...
Port 443 uses transport layer protocols such as TCP (Transmission Control Protocol) or UDP (User Datagram Protocol), which facilitate data flow between devices. Also, it ensures that network traffic reaches its intended destination. How does HTTPS work?
In comparison to other networking protocols, the process behind UDP is fairly simple. A target computer is identified and the data packets, called “datagrams,” are sent to it. There is nothing in place to indicate the order in which the packets should arrive. There is also no process for...
data, using eitherTCP (Transmission Control Protocol) or UDP (User Datagram Protocol). Though UDP isn't as reliable as TCP, it's ideal for time-sensitive communication like computer gaming, video playback, andDNS lookup. In this article, learn what UDP is, how it works, and its ...
