What is ACK (networking)?

ACK stands for acknowledgment; any transmission from a receiving station to a transmitting station communicating that the transmitted data has been received without errors.



On the other hand, if the receiving station determines that the data transmission is late or has not arrived, a NAK (negative acknowledgment) is generated to indicate to the transmitting station that the data should be sent again.

The Transmission Control Protocol (TCP) is a connection-oriented protocol that relies on acknowledgments for successful transmission of data. When a stream of TCP packets is being sent over the network, each packet contains an acknowledgment number indicating the sequence number of the next packet that the receiving station should expect to receive.

ACK – Acknowledge

TCP can use an ACK to acknowledge a series of TCP packets that have been received, rather than just a single packet. A TCP packet sent as an acknowledgment has its ACK flag set to 1 to indicate that the acknowledgment numbers of the packets received are valid.

Public Key Infrastructure (PKI)

Public Key Infrastructure, also known as PKI, is a set of services that support the use of public-key cryptography in a corporate or public setting. A public key infrastructure (PKI) enables key pairs to be generated, securely stored, and securely transmitted to users so that users can send encrypted transmissions and digital signatures over distrusted public networks such as the Internet.

Digital Signature

Digital Signature is an electronic signature that you can use to sign a document being transmitted by electronic means such as e-mail. Digital signatures validate the identity of the sender and ensure that the document they are attached to has not been altered by unauthorized parties during the transmission.
