As far as I remember, message-digest functions distill the information contained within a file (small or large) into a single fixed-length<span>number, typically between 128 and 256 bits in length. This function is designed to protect the integrity of a piece of data to define changes to any part of a message.</span>

Convert the following numbers from decimal to binary, assuming unsigned binary representation:________.
kumpel [21]

Answer:

Binary representations of following are:

A) 35 = 100011

B) 3 = 11

C) 27 = 11011

D) 16 = 10000

Explanation:

The method to generate the binary number from a decimal is :

Keep on dividing the number by 2 and keep on tracking the remainder

And the quotient is again divided and remainder is tracked so that the number is completely divided.

And then write the binary digits from bottom to top.

Please have a look at the method in below examples:

A) 35

\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 35 & 1 \\  2 & 17 & 1 \\   2 & 8 & 0  \\ 2 & 4 & 0  \\ 2 & 2 & 0   \\ 2 & 1 & 1\end{tabular}\end{center}

Writing the remainder from bottom to top.

So, binary number is 100011

B) 3

\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 3 & 1 \\  2 & 1 & 1 \\  \end{tabular}\end{center}

Writing the remainder from bottom to top.

So, binary equivalent is 11.

C) 27

\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 27 & 1 \\  2 & 13 & 1 \\   2 & 6 & 0  \\ 2 & 3 & 1  \\ 2 & 1 & 1   \end{tabular}\end{center}

Writing the remainder from bottom to top.

So, binary equivalent is 11011.

D) 16

\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 16 & 0 \\  2 & 8 & 0 \\   2 & 4 & 0  \\ 2 & 2 & 0  \\ 2 & 1 & 1   \\\end{tabular}\end{center}

Writing the remainder from bottom to top.

So, binary equivalent is 10000.

Answers are:

Binary representations of following are:

A) 35 = <em>100011</em>

B) 3 = <em>11</em>

C) 27 = <em>11011</em>

D) 16 = <em>10000</em>

A hardware compatibility list recommends striping with double parity as storage for an application. In a test environment, a tec
riadik2000 [5.3K]

Answer:

RAID level 5 can be used to compensate a limited number of available disks.

Explanation:

There are two type of RAID

  • Software RAID
  • Hardware RAID

Software RAID

deliver services form the host.

Hardware RAID

provides hardware services.

RAID has levels

0, 1, 5, 6, and 10

RAID 0, 1, and 5 work on both HDD and SSD media,

4 and 6 also work on both media.

RAID 0 :Striping

In this level minimum of two disks,RAID 0 split the file strip the data.Multiple hard drive are used to split the data.

RAID 1 : Mirroring

In this level Minimum two disk require and provide data tendency.

RAID 5 :Stripping with parity

Parity is a binary data.RAID system calculate the value which system used to recover the data.

Most RAID system with parity function store parity blocks.

RAID 5 combines the performance of RAID 0 with redundancy of RAID 1.

RAID 5 level should minimize the fault tolerance.

Part of the central processing unit
AveGali [126]

Answer:

Explanation:

The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations.  It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division).  And logic unit (responsible for comparing, selecting, matching and merging different data or information).  The power and efficiency of the CPU depends on the design of the ALU.  

Next up is the control unit (CU) which directs all the processor’s operations.  It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary).  Then it sends the operation to various parts of the laptop as instructed.  The CU calls the ALU to perform the necessary calculations.  It also coordinates all input/output devices to transfer or receive instructions.

The main job of the memory unit is to store data or instructions and intermediate results.  It’s divided into primary memory and secondary memory to supply data to other units of the CPU.  It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.

Another element of the CPU not depicted in the diagram is transistors.  To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches.  They control the flow of electricity depending on whether the switch is ON or OFF.  Signals turn off and on different combinations of transistors to perform calculations.  A very thin silicon chip can contain several hundred million transistors.
