[9.7] Explain what a firewall is and how a firewall protects your computer from
hackers.
Give this one a try later!
A firewall is a software program or hardware device designed to protect
computers from hackers. Firewalls block access to your computer's logical
ports and help keep your computer's network address secure. Firewalls use
packet filtering to identify packets sent to specific logical ports and discard
them. Firewalls use network address translation to assign internal IP
addresses on networks. The internal IP addresses are much more difficult
for hackers to detect.
[2.10] Explain the main functions of the CPU.
Give this one a try later!
The CPU controls all the functions performed by the computer's other
components. The CPU also processes all commands issued to it by
software instructions.
The performance of a CPU is affected by the speed of the processor
(measured in GHz) and the number of processing cores.

, The Internet is the largest computer network in the world, connecting
millions of computers.
Government and military officials developed the early Internet as a reliable
way to communicate in the event of war. Eventually, scientists and
educators used the Internet to exchange research.
Today, we use the Internet and the web (which is a part of the Internet) to
shop, research, communicate, and entertain ourselves.
[7.8] Explain what should be considered before creating a home network.
Give this one a try later!
Most home network routers should support both wireless and wired access
to the Internet.
For a home network to run efficiently, all nodes such as NICs and routers
should use the same Ethernet standard.
