**Networking**
#1 Intercepting messages on a network is known as:
a-Glomming
b-Packet sniffing
c-Networking
d-Packet stuffing
#2 In order to protect messages on the Internet we use:
a-Passwords
b-Encryption
c-TCP
d-IP Addresses
#3 This governs how communications occur across a network:
a-DHCP
b-IP
c-TCP
d-Encryption
#4 Each piece of an IP address is between 0 and:
a-16
b-32
c-64
d-255
#5 This transmits information using light:
a-Coaxial cable
b-Microaves
c-RF
d-Fiberoptic cable
# 6 Which of the following is not part of a packet header:
a-Origin date
b-Sequence number
c-Last node name
d-Origin time
#7 This is responsible for allocating IP addresses to machines on a network:
a-TCP
b-DHCP
c-Packet
d-Switch
