Can is full duplex or half duplex?
The CAN network is based on a half-duplex differential signal.
There are two logical states: dominant and recessive.
The figure below shows the general concept.
This is the HIGH-level CAN bus line which is a differential signal..
What is the example of full duplex?
In a full-duplex system, both parties can communicate with each other simultaneously. An example of a full-duplex device is plain old telephone service; the parties at both ends of a call can speak and be heard by the other party simultaneously.
Is TCP faster than UDP?
A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.
What is required for full duplex?
The following requirements, as stated in the 802.3x standard, must be met for full-duplex operation: The media system must have independent transmit and receive data paths that can operate simultaneously. … Both stations on the LAN are capable of, and have been configured to use, the full-duplex mode of operation.
What UDP stands for?
User Datagram ProtocolUser Datagram Protocol (UDP) – a communications protocol that facilitates the exchange of messages between computing devices in a network. It’s an alternative to the transmission control protocol (TCP).
Does Youtube use UDP?
As I told RTSP is used stream videos . Youtube uses TCP to control messages rather than UDP because of many reason If we use UDP we might get better performance than TCP but UDP will loose many chunks of packet while streaming due to the lossy nature of Internet communications .
Is UDP bidirectional?
There are two types of Internet Protocol (IP) traffic. They are TCP or Transmission Control Protocol and UDP or User Datagram Protocol. TCP is connection oriented – once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol.
Is TCP full duplex?[TCP] is a full duplex protocol, meaning that each TCP connection supports a pair of byte streams, one flowing in each direction. Yes, a TCP connection provides a full-duplex service. Let’s understand the meaning of full-duplex. It means exchanging data(sending and receiving) between two entities at the same time.
Where is UDP used?
UDP is commonly used for applications that are “lossy” (can handle some packet loss), such as streaming audio and video. It is also used for query-response applications, such as DNS queries.
Is Bluetooth full duplex?
half-duplex communication, or full-duplex communication. Bluetooth can send data at more than 64 kilobits per second (Kbps) in a full-duplex link — a rate high enough to support several human voice conversations.
Is WiFi full duplex?
A wired Ethernet network is full duplex, meaning a device can send and receive, or upload and download, simultaneously. WiFi is half duplex, so if a client is sending data to the AP(Access Points), the AP can not also send data to the same or any other client at the same time.
Is UDP secure?
The big security problem with UDP is that you are susceptible to spoofing and DOS attacks. It’s not possible to spoof an address across the internet using TCP since the handshake will never complete. OTOH with UDP there is no implicit handshake – any session maintenance must be done by your code (processing overhead).
