INSTALL O.S. ONTO A NEW DRIVE. THAT'S HOW YOU PARTITION & FORMAT a new drive Example: Windows costs money. "ubuntu" on Linux is open source **PARTITIONING & FORMATTING must happen before you use any new mass storage drive!** . . . . . . . . . RAID LEVELS / FILE STORAGE: RAID 0 (striping) = 2 drives sharing bits of data from a big file. SPEEDS THINGS UP . RAID 1 (mirroring) = 2 drives share identical bits via mirroring each other on both drives. Protects against losing everything. Necessary? It's REDUNDANT. Slows things down . RAID 5 (striping w/parity) = uses 3 drives. First two drives save the old RAID 0 way but new 3rd drive saves a weird "math parity." clones files via binary math . RAID 6 = uses 4 drives. First two drives save the old RAID 0 way but new drives make "math parity" clones of file (via binary math) **Two drives can fail and everything will still be saved** . RAID 10 (striping mirrors) = 4 drives with 2 ...
PSU block / POWER SUPPLIES . . . . . Big block that gives your PC power *they're basically step down transformers Converts AC power to DC power Like puzzle pieces they all fit perfect . . . . . 2 piece ATX POWER CONVERTER (multi coloured wires - indicate YELLOW 12v , RED 5v , and ORANGE 3.3volt ) ATX12V is typical power for CPU . . . . . . . . SOME OLD ASS COMPUTERS USED "MOLEX" TINY MINI CONNECTOR for floppy drives . . . . . . . . Once again - small black SATA CONNECTORS . . . . . . . PCIE connectors are for video cards . . . . . . . huge MODULAR CONNECTOR like a big adaptor - so you don't have cables going everywhere Purists say you should use soldered power supply *not the big MODULAR CONNECTOR . . . . . . . 80PLUS RATINGS GUIDE (power efficiency rating) . . . . . . . HEAT SINK & HEAT DISSIPATORS - COOLING BAR FINS + FANS for air flow . . . . . . . When systems OVERHEAT they REBOOT BIGGER FANS *LESS NOISY because they TURN SLOWER (liqui...
IPv4 ADDRESSes built the internet. But they ran out of combos in late 90s NAT "network address translation" fixed this You used to have to be manually assigned a network ID via your internet provider Downside of this was your network ID was public to hackers = therefore FIREWALL was born . If someone got past your " Firewall " all of the PCs on your WAN & LAN were vulnerable **NAT fixed this too** NAT router/gateway will now give private IP addresses to all PCs on a LAN . Your private IP ADDRESS goes through NAT gateway & the gateway camouflages your address as its own LAN address (Kinda slows things down unfortunately) . .
