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 127.0.0.1is used to check if the network adapter is working correctly and installed properly. - Private IP Address:
172.32.1.244and192.168.99.55are 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
192.168.0.0and subnet mask255.255.0.0is192.168.0.0/16.
Help Desks
- Purpose: Help desks (or service desks) are crucial for providing solutions and resolving issues faced by customers.
