Answer:
The User Datagram Protocol (UDP) is called the connectionless protocol because:
It does not attempt to fix bad packets or resend lost packets.
Explanation:
Ports are openings or entrance doors through which data packages have access to a PC or server. TCP and UDP are transport protocols with port numbers. TCP means Transmission Control Protocol. They are used to connect two devices over the internet and other networks. UDP means User Datagram Protocol. They are used to connect applications and to speed the transfer of data. Comparatively, UDP is faster, simpler, and more efficient than TCP. TCP enables retransmission of lost data packets, which UDP cannot do.
I guess the answer in the blank is processes.
Activities called processes involve the microprocessor receiving commands as software carries out tasks and while input arrives from the keyboard, mouse, and other devices.
Answer: Sounds like you are talking about “Distributed memory systems” which use multiple computers to solve a common problem, with computation distributed among the connected computers (nodes) and using message-passing to communicate between the nodes.
