Study Notes

Network Troubleshooting

DHCP Server Issues: Several users experiencing similar IP addresses beginning with 169.254.3... is a strong indicator of a problem with the DHCP server.
Ping Command: ping 127.0.0.1 is used to check if the network adapter is working correctly and installed properly.
Private IP Address: 172.32.1.244 and 192.168.99.55 are both private IP addresses.

Virtual Machines

Advantages: Virtual Machines (VMs) offer numerous benefits including:
- Running multiple operating systems on a single host OS.
- Cost savings through efficient hardware utilization.
- Easy creation of test environments for projects and testing.

Networking Concepts

Programs: Programs store their data on the hard drive, taking up disk space.
Processes: Processes are the running instances of programs and reside in memory.
CIDR Notation: The CIDR notation for the network ID 192.168.0.0 and subnet mask 255.255.0.0 is 192.168.0.0/16.

Help Desks

Purpose: Help desks (or service desks) are crucial for providing solutions and resolving issues faced by customers.
