Router vs Switch vs Access Point: What Each Box Actually Does
Routers move traffic between networks, switches connect wired devices on a network, and access points provide Wi-Fi access to that network.
RAID vs Backup: What Each One Protects
Redundant RAID can preserve availability through specified drive failures, while independent backups preserve recovery history; RAID 0 has no redundancy, and neither array health nor copy status proves restoration.
Public IP vs Private IP: What Your Router Is Hiding
Public addressing supports global routing, not guaranteed reachability; compare the router's WAN address with the observed external address and check upstream NAT, VPNs, IPv6, and firewall policy separately.
PoE vs PoE+ vs PoE++: Why Cameras and APs Reboot
Power over Ethernet sends power and data over one cable. The standard, switch budget, cable quality, and device draw all matter.
Ping vs Tracert/Traceroute: Reachability vs Path Troubleshooting
Use ping for ICMP reachability and round-trip time, and traceroute for answering probe hops; compare actual application behavior before treating silence or an intermediate delay as failure.
Patch Panel vs Switch: What Belongs in the Rack
A patch panel terminates and organizes cables. A switch forwards network traffic. They work together but do completely different jobs.
Password Manager vs Browser Passwords
Compare browser, operating-system, and dedicated password managers by device support, sharing, and recovery needs; protect the sync account and treat exports as plaintext unless documented otherwise.
NTFS vs exFAT vs FAT32: Which Format Should You Use?
Choose NTFS for Windows-native storage, exFAT for tested cross-platform transfers, or FAT32 when required; FAT32 files must be smaller than 4 GiB, and formatting requires a verified separate backup.
NAT vs Routing: What Happens When Traffic Leaves Your LAN
Routing decides where packets go. NAT rewrites addresses. Home networks usually use both, but they are not the same job.
NAS vs DAS vs Cloud: Choosing Storage by Workflow
NAS shares storage over the network, DAS attaches directly to one computer, and cloud storage syncs or hosts data through a provider.
