(ED) What is NIC short for
Network interface card
(JD) what does a switch do?
connects all devices together

connects devices wirelessly
(H.P) How long can a fiber optic cable before losing its effectivity?
(GO)
what does a NIC do?BA
provides a device connection to the network
what is the difference between a client and peer to peer server?
a client server is controlled by a centeral device where all of the data is stored whereas a peer-peer is an agreement between devices when all data is stored locally to the device it belongs to.

which protocol controls how messages a formatted ?BA
TCP
what are the three protocols that deal with emails?ba
POP, SMTP, IMAP

(J.E) What is Caesar cipher?
A simple encryption algorithm is the caesar cipher. The key is a number, which represents an offset.
Each character in the plaintext is replaced by the corresponding letter (if the key is -5 J is replaced by E)
What is the most secure encryption method we have learnt? (DV)
Asymmetric Encryption
GO what does smtp stand for
simple mail transfer protocol
what is error rate?ba
the reliablity of the connection, the amount of errors that occur
(J.E) What is the difference between a LAN and WAN?
Lan is for only a small area and a Wan is for long distances
what is a fiber optic cable made out of?ba
thin strands of glass
(EC) What is encryption used for?
Encryption is used for hiding/cloaking your data but can only be undertsood by using a certain key
GO what does the s in https stand for
secure
