RAID

-
RAID -> Redundant Array of Independent Disks -> It is a method in which multiple hard disks are placed in parallel and are controlled as if they were one disk unit -> It has 6 Levels RAID0 to RAID6 RAID Levels -> RAID0 : Writes block of fixed size in multiple disks. -> RAID1 : Records same data on two disk for safety. -> RAID2 : Correct error -> RAID3 and RAID4 : Detect error -> RAID5 : each data block is assigned a parity value. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost. -> RAID6 : extends RAID 5 by adding another parity block. the data is recoverable even when two disks fail.

What Is derivative? (Part - 1)

What Is derivative? (Part - 1) Derivative is a simple thing. It’s just the difference of a variable. But how? Think of time, let a person started a journey towards bus stand at time t1 = 3 and reached at t2 = 7. In this case the derivative dt = t2-t1 = 7-3 = 4. Easy! But in real life things are not that easy. Because we have do derive the difference of a variable with respect to another variable unlike our time example where there was only one variable. For example we can see the equation y = x. Here we have to find the difference in y with respect to the change in variable x. In other word we have to find the derivative of y with respect to x which is dy/dx. Fortunately for us this is very easy. Pretty easy right. But we are going to prove it so that we can use the same theory to prove more complex derivatives. So we are going to plot this function into graph. Let’s find some value of x and values of y for the respective value of x below. ...

LINEAR ALGEBRA (Part-4) - Identity and Inverse Matrices

LINEAR ALGEBRA (Part-4) Identity and Inverse Matrices Identity Matrix It is a square matrix that do not change any matrix or vector when multiplied with. Means If a matrix A 2,2 is multiplied by identity matrix I 2,2 then the result will be A 2,2 . So, A 2,2 ❌ I 2,2 = A 2,2 A 2,2 = [           I 2,2 = [           A 2,2 = [             A 2,2 = [         2 3   ❌       1 0   =       2❌1 ➕ 3❌0   2❌0 ➕ 3❌1   =       2 3     5 4           0 1           5❌1 ➕ 4❌0   5❌0 ➕ 4❌1           5 4   ]             ]             ]               ]       Identity matrix looks like above I 2,2 .
