DOS COMMANDS
to check your computer name use hostname command on Dos
ipconfig –> to check ip settings
netsh /netshell–> to assign ip from dos
ping 10.0.0.2–> to check connectivity b/w computer
how to identify if comp is not on same nw: on the basis of nw id we can identify
ip add has 2 add in it
10.0.0–> nw id
255.255.255 –> subnet mask difines network id
hostid is 0 here because in subnet mask there are 3 times 255 so the last one is hostid
0
if comp r not in the same nw (same nw id) then they use router to identify each other
win+pause key to open sys prop
Drivers are in shell
formula for Virtual Memory:
VM size shouldn't be that large as then searching will slow down.
for workstation -> 1.5 * RAM
for db server -> 10GB
on High Performance system VM should be on RAID0 Disk System or store it on the fastest avialble disk you have
