A digital certificate is an electronic “credit card” that establishes your
credentials when doing business or other transactions on the Web. It is issued by a certification
authority (CA). It contains your name, a serial number, expiration dates, a copy of the certificate
holder's public key (used for encrypting and decrypting messages and digital signatures), and the
digital signature of the certificate-issuing authority so that a recipient can verify that the certifi-
cate is real.

RUNK
—
An Ethernet Trunk service represents a point-to-point connection between
two ports of two devices. Ethernet frames transported by the connection are encapsulated
according to IEEE 802.1Q protocol. The each tag ID value in 802.1Q encapsulated Ethernet
frames distinguishes an Ethernet traffic flow. Thus, an Ethernet trunk can aggregate multiple
Ethernet VLANs through a same connection which is why “trunk” describes these.
