GrAded A+).
Clients - SOLUTION-Devices that users access the network with
(e.g- workstations, tablets, laptops, phones, smart tvs, etc)
Servers - SOLUTION-Provide resources to the network. (e.g-
email, web, file, etc.)(Can live on dedicated hardware or rely
on specialized software that allows a device to act as a
server for other clients on the network)
What is a hub in networking? - SOLUTION-An older network
device that connects other devices like clients and servers
over a local area network.
What is a limitation of hubs? - SOLUTION-They can increase
network errors due to their broadcasting nature.
,What is the progression of network devices from hubs? -
SOLUTION-Hub --> Bridges --> Switches
Switches - SOLUTION-"Smarter hubs" that provide more security
and more efficient bandwidth utilization. (Switches are used
to connect network devices and only forward traffic from one
port to the intended destination)
Wireless Access Points (WAPs/APs) - SOLUTIONAllow wireless
devices to connect to the wired network
What is the primary function of a router? - SOLUTION-To connect
different networks together.
What protocol do modern routers predominantly rely on? -
SOLUTION-Internet Protocol (IP).
What do routers use to route traffic across the network? -
SOLUTION-Different types of routing protocols.
,What are firewalls? - SOLUTION-Security barriers between
internal networks and the external world. (Can be hardware
based, software based, or a combination of both)
What do firewalls monitor? - SOLUTION-Incoming and outgoing
network traffic.
What do firewalls control? - SOLUTION-Traffic based upon
predetermined security rules.
What are load balancers? - SOLUTION-Devices or software that
distribute network or application traffic across multiple
servers.
What is the purpose of load balancers? - SOLUTIONTo increase
the efficiency, capacity, and reliability of servers.
How do load balancers improve network performance? -
SOLUTION-By preventing any one server from becoming a
bottleneck.
, What is a proxy? - SOLUTION-Acts as an intermediary between a
user's device and the internet.
What functionalities can a proxy provide? - SOLUTION-Web
filtering, shared network connections, and data caching to
improve overall performance.
How can a proxy enhance security and privacy? -
SOLUTION-By hiding the user's real IP address and limiting
exposure to the internet.
Intrusion Detection System (IDS) - SOLUTION-Detect
unauthorized access or anomalies and alert administrators.
Intrusion Prevention System (IPS) - SOLUTION-Will detect
threats, but also take action to prevent intrusion. (Such as
blocking traffic from entering your network or dropping any
kind of harmful packets that may be attempting to get to your
network)
