LVM(Logical Volume Manager)

  • LVM is a method of allocating hard drive space into logical volumes that can be easily re-sized.

  • With LVM, the hard drive or set of hard drives is allocated to one or more physical volumes.

  • The physical volumes are then combined into volume groups.

  • Each volume group is divided into logical volumes which are formatted with a file system like etx3 or ext4 and then they are mounted.

Profit and Loss

Cost Price (C.P.) The price at which an article is purchased or manufactured is called its cost price. Selling Price (S.P.) The price at which an article is sold, is called its selling price. Profit If the selling price of an article is greater than its cost price, we say that there is a profit or gain. Profit = Selling Price - Cost Price When S.P.>C.P. Profit = S.P. - C.P. S.P.= C.P.+Profit C.P.=S.P.-Profit Profit % = Profit/C.P. * 100 Profit = Profit % * C.P. When C.P.  and Profit% are given then, S.P. = C.P. * ((100+Profit %)/100) When S.P. and Profit % are given then C.P.= 100* S.P./100+ Profit % Loss If the selling price of an article is less than tits cost price, we say that there is a loss. Loss = Cost Price - Selling Price  When C.P.>S.P. Loss = C.P. - S.P. S.P.= C.P.-Loss C.P.=S.P.+Loss Loss % = Loss/C.P. * 100 Loss = Loss % * C.P. When C.P.  and Loss % are given then, S.P. = C.P. * ((100-Loss %)/100) When ...
