Networks
Setting up computer networks is essential
for enabling communication between
multiple devices. This topic covers both
wired and wireless networking
techniques. Proper network setup
enhances collaboration and resource
sharing in environments like offices or
classrooms.
16. Types of Computer
Networks
1. Local Area Networks (LAN) connect devices
within a limited area.
2. Wide Area Networks (WAN) cover larger
geographical distances.
3. Wireless networks facilitate connectivity
without physical cables.
17. Network Setup Process
Setting up a network involves several steps starting with the
physical connection of devices. Next, configure the routers
and switches to manage data flow. Finally, secure the network
with passwords and firewalls to protect against unauthorized
access.
18. Setting Up Servers
Servers play a crucial role in managing
network resources and services. This
section introduces various types of
servers and their specific functions.
Understanding how to set up and
manage servers is vital for maintaining a
robust network.
