Virtual Memory: the operating systems of all modern computers have virtual memory where a disk is used to transfer the data temporarily from the RAM when physical memory of the computer falls short. Though it is cheap but it does not allow computers to have more memory and frequent swapping even makes the PC slow.

Tiered memory: has the fastest data storage and even has a good storage capacity but is pretty expensive.

Volatile memory: volatile memories have good performance in terms of speed and storage but they still are a little expensive in comparison to non-volatile memory.

Non-volatile memory: they do not provide with large storage capacities.

Given the following adjacency matrix, what is the approximate rank vector after one iteration of the power iteration method (use

ValentinkaMS [17]

Note: The matrix referred to in the question is: $M = \left[\begin{array}{ccc}1/2&1/3&0\\1/2&1/3&0\\0&1/3&1\end{array}\right]$

Answer:

a) [5/18, 5/18, 4/9]'

Explanation:

The adjacency matrix is $M = \left[\begin{array}{ccc}1/2&1/3&0\\1/2&1/3&0\\0&1/3&1\end{array}\right]$

To start the power iteration, let us start with an initial non zero approximation,

$X_o = \left[\begin{array}{ccc}1\\1\\1\end{array}\right]$

To get the rank vector for the first Iteration:

$X_1 = MX_0$

$X_1 = \left[\begin{array}{ccc}1/2&1/3&0\\1/2&1/3&0\\0&1/3&1\end{array}\right]\left[\begin{array}{ccc}1\\1\\1\end{array}\right] \\\\X_1 = \left[\begin{array}{ccc}5/6\\5/6\\4/3\end{array}\right]\\$

Multiplying the above matrix by 1/3

$X_1 = \left[\begin{array}{ccc}5/18\\5/18\\4/9\end{array}\right]$
