Microsoft Drive Optimizer (formerly Disk Defragmenter) is a utility in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique called defragmentation. Defragmenting a disk minimizes head travel, which reduces the time it takes to read files from and write files to the disk.[1] Beginning with Windows XP, Microsoft Drive Optimizer also reduces system startup time.

A Loop executes the sequence of statements many times until the stated condition becomes false. A loop consists of two parts, a body of a loop and a control statement. The control statement is a combination of some conditions that direct the body of the loop to execute until the specified condition becomes false. The purpose of the loop is to repeat the same code a number of times.

A while loop is the most straightforward looping structure. Syntax of while loop in C programming language is as follows:
<pre> while (condition) { statements; }</pre> -
A do...while loop in C is similar to the while loop except that the condition is always executed after the body of a loop. It is also called an exit-controlled loop.
<pre> do { statements } while (expression);</pre>
Syntax of do...while loop in C programming language is as follows: -
A for loop is a more efficient loop structure in 'C' programming. The general structure of for loop syntax in C is as follows:
<pre> for (initial value; condition; incrementation or decrementation ) { statements; }</pre>

The most basic functions of a computer are to take input through the input input, process it using the CPU and produce an output through the output units. This process can be represented with the help of the Input – Process – Output cycle (IPO cycle). Every task hendled by the computer follows this cycle. The working of this cycle can be stated as follows:
i. Input is supplied through the input peripherals
ii. The supplied input is read and is then processed by the CPU
iii. The processed data is then output through the output devices

Jacquard loom, also called Jacquard Attachment, orJacquard Mechanism, in weaving, device incorporated in special looms to control individual warp yarns. It enabled looms to produce fabrics having intricate woven patterns such as tapestry, brocade, and damask, and it has also been adapted to the production of patterned knitted fabrics. The Jacquard machine is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom. The machine was invented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740).The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence.[6] Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Several such paper cards, generally white in color, can be seen in the images below. Chains, like Bouchon's earlier use of paper tape, allowed sequences of any length to be constructed, not limited by the size of a card.

Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.

(11110101)2 = (365)8
Step by step solution
Step 1: Write down the binary number
(011110101)2
Group all the digits in sets of three starting from the LSB (far right). Add zeros to the left of the last digit if there aren't enough digits to make a set of three.
011 110 101
Step 2: Use the table below to convert each set of three into an octal digit. In this case,
011=3, 110=6, 101=5.
So, the number 365 is the octal equivalent to 11110101 in binary.
To convert from binary to octal use the following table:
| Bin: | 000 | 001 | 010 | 011 | 100 | 101 | 110 | 111 |
| Octal: | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |

The devices that are used to display the information of the results are known as output devices. While the devices whose main function is to give instructions and data to the computer are called input devices.The various examples of input data are a mouse, keyboard, light pen, etc.

When raw data are processed and converted into meaningful form then it is referred to as Information. A data processing unit (DPU) is a programmable electronic component that processes streams of data. The data is transmitted to and from the component as multiplexed packets of information. To be effectively used in making decisions, data must go through a transformation process that involves six basic steps: 1) data collection, 2) data organization, 3) data processing, 4) data integration, 5) data reporting and finally, 6) data utilization.

converting a Binary to Decimal number would be:
| Decimal Digit Value | 256 | 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 |
| Binary Digit Value | 1 | 0 | 1 | 1 | 0 | 0 | 1 | 0 | 1 |
By adding together ALL the decimal number values from right to left at the positions that are represented by a “1” gives us: (256) + (64) + (32) + (4) + (1) = 35710 or three hundred and fifty seven as a decimal number.
Then, we can convert binary to decimal by finding the decimal equivalent of the binary array of digits 1011001012 and expanding the binary digits into a series with a base of 2 giving an equivalent of 35710 in decimal or denary.
Note that in number conversion systems “subscripts” are used to indicate the relevant base numbering system, 10012 = 910. If no subscript is used after a number, then it is generally assumed to be decimal.
Repeated Division-by-2 Method
We have seen above how to convert binary to decimal numbers, but how do we convert a decimal number into a binary number. An easy method of converting decimal to binary number equivalents is to write down the decimal number and to continually divide-by-2 (two) to give a result and a remainder of either a “1” or a “0” until the final result equals zero.
So for example. Convert the decimal number 29410 into its binary number equivalent.
| Number | 294 |
Dividing each decimal number by “2” as shown will give a result plus a remainder. If the decimal number being divided is even then the result will be whole and the remainder will be equal to “0”. If the decimal number is odd then the result will not divide completely and the remainder will be a “1”. The binary result is obtained by placing all the remainders in order with the least significant bit (LSB) being at the top and the most significant bit (MSB) being at the bottom. |
|
| divide by 2 | |||
| result | 147 | remainder | 0 (LSB) |
| divide by 2 | |||
| result | 73 | remainder | 1 |
| divide by 2 | |||
| result | 36 | remainder | 1 |
| divide by 2 | |||
| result | 18 | remainder | 0 |
| divide by 2 | |||
| result | 9 | remainder | 0 |
| divide by 2 | |||
| result | 4 | remainder | 1 |
| divide by 2 | |||
| result | 2 | remainder | 0 |
| divide by 2 | |||
| result | 1 | remainder | 0 |
| divide by 2 | |||
| result | 0 | remainder | 1 (MSB) |
This divide-by-2 decimal to binary conversion technique gives the decimal number 29410 an equivalent of 1001001102 in binary, reading from right to left. This divide-by-2 method will also work for conversion to other number bases.
Then we can see that the main characteristics of a Binary Numbering System is that each “binary digit” or “bit” has a value of either “1” or “0” with each bit having a weight or value double that of its previous bit starting from the lowest or least significant bit (LSB) and this is called the “sum-of-weights” method.
So we can convert a decimal number into a binary number either by using the sum-of-weights method or by using the repeated division-by-2 method, and convert binary to decimal by finding its sum-of-weights.
