1. Click Edit → Find & Replace (or) Ctrl + F

2. The Find & Replace dialog box appears as shown below.

Steps to And & replace a text:
1. Type the text you want to find in the Search for box

All occurrences of Bombay are highlighted.

5. Click Replace AH button, Writer replaces all matches.
This will replace all occurrences of “Bombay” with “Mumbai”.

6. Enable Match case to perform the search case sensitively so that uppercase and lower cases are distinguished separately.

7. Enable Whole Words only to make the search more specific to words used separately alone.

Question 4.
Explain Page formatting in writer.
Answer:
The most important thing in a word processor is how to format the page with elements such as margins, numbering, page layout, headers and footers. Formatting our pages makes them look more attractive and makes them easier to read.

Setting the Page Size and Margins – Changing Page Size:
The default page size in writer is 8.5 x 11″, the same as that of a standard A4 printing paper. However, for different types of documents, you may need to change the page size.

Changing page margins:
Page margins are the white space around the top, bottom, left, and right of your document. Margins . let Writer know where to start placing the text at the top of a document, when to move on to the next page at the bottom, where to start typing text on the left side, and where to stop and move to the next line on the right.

Changing or setting page margins in Open office writer can be done in two ways:

• Using the Rulers – quick and easy, but does not have precise values.
• Using the Page Style dialog box – can specify precise values for the margins.

Page Orientation:
Page orientation refers to how the document will be displayed on screen and printed. There are two different orientations:

Landscape :
The width of the document is more than the height. This is best suited for displaying professional photos, invitations, albums, tables etc.

Portrait:
This is the most common and default orientation. Here, the height of the document is more than the width. Normally books, newspapers will be displayed in this format.

Changing the page color is not quite common. To do so, in the Page style dialog box, select Background tab, In As option click on color and select the “color” from the color palette or select “graphic” to apply an image as a page background Borders can be applied to an entire document, an entire page, paragraph, or just to certain sections of the document. From the page style dialog box, select the Border tab, the user defined area helps to define the area of borders, the line style of borders, color of borders can be selected.

Header and Footer:
The header is a section of the document that appears in the top margin, which displays the title or chapter name, author name of a document. The footer is a section of the document that appears in the bottom margin of the page which displays the page number, date, time etc. which gets displayed on all the pages automatically.

Question 7.
What is indenting text? Explain the various methods.
Answer:
Indent is the distance from the left and right margin of a paragraph. It is used to improve the efficiency and readability of the paragraph and makes the paragraph look more attractive. There are four types of indents:

• Left Indent
• Right Indent
• First Line Indent and
• Hanging Indent

Left indent: The Left indent controls the space between the paragraph and the left margin. This is the default indent. Each click on the Increase indent icon moves the paragraph Vi inch away from the left margin.

The left indent can also be applied by Format → Paragraph → Indents & Spacing tab, enter a value in the “before text” spin box. This results in a left indent.

Right Indent: The Right indent controls the space between the paragraph and the right margin. Each click on the decrease indent icon removes the indent applied by the Increase indent. The Right indent can be applied by the dialog box method. Select Format → Paragraph → Indents & Spacing tab, enter a value in “after text” spin box. This results in a right indent.

First Line Indent: A first-line indentation indents the first line of the paragraph. It is the most common way to start a new paragraph. This indent can be applied by Format → Paragraph → Indents & Spacing tab, select first line option in the Indent group, enter a positive value which results in first line indent.

Hanging indent: This is a special kind of indent where the first line of the paragraph alone hangs outside leaving the rest of the text. To apply Hanging indent, a negative value is given in the “first line” option of the paragraph dialog box.

Example:

Question 8.
Explain Bullets and Numbering text with suitable example.
Answer:
Bullets and numbering are used to emphasize list of things and make list easy to read and follow. It provides an excellent way to segregate, list and organize information for a reader.

Bullets: This is a paragraph level attribute that applies a bullet character to the start of the paragraph. In bulleted lists, each paragraph begins with a bullet character.

This is suitable when the text has to be presented as a list of items preceded by a bullet symbol and no sequence has to be followed. Bullets are quickly created by clicking on the bullet icon

Numbering : This attribute applies a numeral to the start of the paragraph. Numbering is more suitable when the text has to be presented as a sequence. In numbered list, each paragraph begins with an expression that includes a number or letter and a separator such as a period or parenthesis.

The numbers in a numbered list are updated automatically when we add or remove paragraphs in the list. Numbering is quickly created by clicking on the numbering icon .

Style of Bullets and Numbering:
The default type of bullet is ( . ) and the default type of numbering is (1, 2, 3 …. ). The style of bullets and numbering can be changed by applying the following steps:

Explain In Detail

Question 1.
Explain the characteristics of a microprocessor.
Answer:
A Microprocessor’s performance depends on the following characteristics:
(a) Clock speed
(b) Instruction set
(c) Word size
(a) Clock Speed:
Every microprocessor has an internal clock that regulates the speed at which it executes instructions. The speed at which the microprocessor executes instructions is called the clock speed. Clock speed is measured in MHz (Mega Hertz) or in GHz (Giga Hertz).

(b) Instruction Set:
A command which is given to a computer to perform an operation on data is called an instruction. Basic set of machine level instructions that a microprocessor is designed to execute is called as an instruction set.

This instruction set carries out the following types of operations:

• Data transfer
• Arithmetic operations
• Logical operations
• Control flow
• Input/output

(c) Word Size
The number of bits that can be processed by a processor in a single instruction is ailed its word size. Word size determines the amount of RAM that can be accessed by a microprocessor at one time and the total number of pins on the microprocessor, total number of input and output pins in urn determines the architecture of the microprocessor.

Question 2.
How the read and write operations are performed by a processor? Explain.
Answer:
The Central Processing Unit(CPU) has a Memory Data Register (MDR) and a Memory Address Register (MAR). The Memory Data Register (MDR) keeps the data which is transferred between the Memory and the CPU.

The Program Counter (PC) is a special register CPU which always keeps the address of the instruction to be executed. The Arithmetic [Logic unit of CPU places the address of the memory to be fetched, into the Memory Address Register.

A bus is a collection of wires used for communication between the internal components are computer. The address bus is used to point a memory location. A decoder, a digital circuit is used to point to the specific memory location where the word can be located.

The address register is connected with the address bus, which provides the address of the instruction. A data bus is used to transfer data between the memory and the CPU.

The data bus is bidirectional and the address unidirectional. The control bus controls both read and write. The read operation fetches data from by and transfers to MDR. A single control line performs two operations like Read/Write using 1 or 2. Also, the write operation transfers data from the MDR to memory. This organization is shown in the following Figure.

If the size of the MDR is eight bits, which can be connected with a word in the memory which is also eight bits size. The data bus has eight parallel wires to transfer data either from MDR to word or word to MDR based on the control(Read or write). This control line is labeled as R/W, which becomes 1 means READ operation and 0 means WRITE operation.

The read operation transfers the data(bits) from word to Memory Data Register. The write operation transfers the data(bits) from Memory Data Register to word.

Question 3.
Arrange the memory devices in ascending order based on the access time.
Answer:
Different memory devices are arranged according to the capacity, speed and cost as shown in the following Figure.

The memory devices in ascending order based on the access time:
a) Hard disk
b) Main memory (RAM)
c) Cache memory

Question 4.
Explain the types of ROM.
Answer:
Types of ROM
Read Only Memory (ROM):
Read Only Memory refers to special memory in a computer with pre-recorded data at manufacturing time which cannot be modified. The stored programs that start the computer and perform diagnostics are available in ROMs.

ROM stores critical programs such as the program that boots the computer. Once the data has been written onto a ROM chip, it cannot be modified or removed and can only be read. ROM retains its contents even when the computer is turned off. So, ROM is called as a non-volatile memory.

Programmable Read Only Memory (PROM):
Programmable read only memory is also a non-volatile memory on which data can be written only once. Once a program has been written onto a PROM, it remains there forever. Unlike the main memory, PROMs retain their contents even when the computer is turned off.

The PROM differs from ROM. PROM is manufactured as a blank memory, whereas a ROM is programmed during the manufacturing process itself. PROM programmer or a PROM burner is used to write data to a PROM chip. The process of programming a PROM is called burning the PROM.

Programmable Read Only Memory (EPROM):
Erasable Programmable Read Only Memory is a special type of memory which serves as a PROM, but the content can be erased using ultraviolet rays. EPROM retains its contents until it is exposed to ultraviolet light. The ultraviolet light clears its contents, making it possible to reprogram the memory. An EPROM differs from a PROM, PROM can be written only once and cannot be erased.

Electrically Erasable Programmable Read Only Memory (EEPROM) :
Electrically Erasable Programmable Read Only Memory is a special type of PROM that can be erased by exposing it to an electrical charge. Like other types of PROM, EEPROM retains its contents even when the power is turned off. Comparing with all other types of ROM, EEPROM is slower in performance.

What are the memory access methods?
Answer:
The memory access methods are –

1. Sequential Access : The memory is accessed in an orderly manner from starting to end.
2. Random Access : Any byte of memory can be accessed directly without navigating through previous bytes.

Question 5.
Write note on Main Memory.
Answer:
The main memory is otherwise called as Random Access Memory. This is available in computers in the form of Integrated Circuits (ICs). It is the place in a computer where the Operating System, Application Programs and the data in current use are kept temporarily so that they can be accessed by the computer’s processor.

RAM is a volatile memory, which means that the information stored in it is not permanent. As soon as the power is turned off, whatever data that resides in RAM is lost. It allows both read and write operations.

Question 6.

A CD or CD-ROM is made from 1.2 millimeters thick, polycarbonate plastic material. A thin layer of aluminum or gold is applied to the surface. CD data is represented as tiny indentations known as “pits”, encoded in a spiral track moulded into the top of the polycarbonate layer. The areas between pits are known as “lands”. A motor within the CD player rotates the disk. The capacity of an ordinary CD- ROM is 700MB.

DVD-ROM :
A DVD (Digital Versatile Disc or Digital Video Disc) is an optical disc capable of storing up to 4.7 GB of data, more than six times what a CD can hold. DVDs are often used to store movies at a better quality. Like CDs, DVDs are read with a laser.

The disc can have one or two sides, and one or two layers of data per side; the number of sides and layers determines how much it can hold. A 12 cm diameter disc with single sided, single layer has 4.7 GB capacity, whereas the single sided, double layer has 8.5 GB capacity. The 8 cm DVD has 1.5 GB capacity.

The capacity of a DVD-ROM can be visually determined by noting the number of data sides of the disc. Double-layered sides are usually gold – coloured, while single-layered sides are usually silver-coloured, like a CD.

Part – III

Short Answer

Question 1.
Write about binary number system.
Answer:
There are only two digits in the Binary system, namely, 0 and 1. The numbers in the binary system are represented to the base 2 and the positional multipliers are the powers of 2.

The left most bit in the binary number is called as the Most Significant Bit (MSB) and it has the largest positional weight. The right most bit is the Least Significant Bit (LSB) and has the smallest positional weight.

Question 2.
Explain Hexadecimal number system.
Answer:
A hexadecimal number is represented using base 16. Hexadecimal or Hex numbers are used as a shorthand form of binary sequence. This system is used to represent data in a more compact manner. Since 16 symbols are used, 0 to F, the notation is called hexadecimal.

The first 10 symbols are the same as in the decimal system, 0 to 9 and the remaining 6 symbols are taken from the first 6 letters of the alphabet sequence, A to F, where A represents 10, B is 11, C is 12, D is 13, E is 14 and F is 15.

Question 3.
Give the procedure to convert decimal to octal.
Answer:
To convert Decimal to Octal, “Repeated Division by 8” method can be used) In this method, we have to divide the given number by 8.

Example:
Convert (65)₁₀ into its equivalent Octal number.

Question 4.
Give the procedure to convert Octal to Decimal
Answer:
To convert Octal to Decimal, we can use positional notation method:

1. Write down the Octal digits and list the powers of 8 from right to left (Positional Notation).
2. For each positional notation of the digit write the equivalent weight.
3. Multiply each digit with its corresponding weight.
4. Add all the, values.

Example:
Convert (1265)₈ to equivalent Decimal number.

(1265)₈ = 512 x 1 + 64 x 2 + 8 x 6 + 1 x 5 = 512 + 128 + 48 + 5
(1265)₈ = (693)₁₀

Question 5.
How will you convert Hexadecimal to Decimal?
Answer:
To convert Hexadecimal to Decimal we can use positional notation method:

1. Write down the Hexadecimal digits and list the powers of 16 from right to left (Positional Notation)
2. For each positional notation written for the digit, now write the equivalent weight.
3. Multiply each digit with its corresponding weight
4. Add all the values to get one final value.

Example:
Convert (25F)₁₆ into its equivalent Decimal number.

(25F)₁₆ = 2 x 256 + 5 x 16 + 15 x 1 = 512 + 80 + 15
(25F)₁₆ = (607)₁₀

Question 6.
Write about binary representation for signed numbers.
Answer:
Computers can handle both positive (unsigned) and negative (signed) numbers. The simplest method to represent negative binary numbers is called Signed Magnitude. In signed magnitude method, the left most bit is Most Significant Bit (MSB), is called sign bit or parity bit.

The numbers are represented in computers in different ways:

1. Signed Magnitude representation
2. 1’s Complement
3. 2’s Complement

Question 7.
Explain ASCII code in detail.
Answer:
This is the most popular encoding system recognized by United States. Most of the computers use this system. Remember this encoding system can handle English characters only. This can handle 27 bit which means 128 characters.

In this system, each character has individual number .The new edition ASCII -8, has 28 bits and can handle 256 characters are represented from 0 to 255 unique numbers.

The ASCII code equivalent to the uppercase letter ‘A’ is 65. The binary representation of ASCII (7 bit) value is 1000001. Also 01000001 in ASCII-8 bit.

Question 8.
Explain Unicode in detail.
Answer:
This coding system is used in most of the modern computers. The popular coding scheme after ASCII is Unicode. ASCII can represent only 256 characters. Therefore English and European Languages alone can be handled by ASCII.

Particularly there was a situation, when the languages like Tamil, Malayalam, Kannada and Telugu could not be represented by ASCII.

Hence, the Unicode was generated to handle all the coding system of Universal languages. This is 16 bit code and can handle 65536 characters. Unicode scheme is denoted by hexadecimal numbers.

To convert Decimal to Binary “Repeated Division by 2” method can be used. Any Decimal number divided by 2 will leave a remainder of 0 or 1. Repeated division by 2 will leave a sequence of 0s and Is that become the binary equivalent of the decimal number.

Suppose it is required to convert the decimal number N into binary form, dividing N by 2 in the decimal system, we will obtain a quotient N1 and a remainder R1, where R1 can have a value of either 0 or 1. The process is repeated until the quotient becomes 0 or 1. When the quotient is ‘O’ or ‘1’, it is the final remainder value. Write the final answer starting from final remainder value obtained to the first remainder value obtained.

Example:
Convert (65)₁₀ into its equivalent binary number.

Question 2.
Explain decimal to binary conversion using Sum of powers of 2 method.
Answer:
A decimal number can be converted into a binary number by adding up the powers of 2 and then adding bits as needed to obtain the total value of the number.

a) Find the largest power of 2 that is smaller than or equal to 65.
6510 > 6410

b) Set the 64’s bit to 1 and subtract 64 from the original number
65 – 64 = 1

c) 32 is greater than the remaining total.
Therefore, set the 32’s bit to 0.

d) 16 is greater than the remaining total.
Therefore, set the 16’s bit to 0.

e) 8 is greater than the remaining total.
Therefore, set the 8’s bit to 0.

f) 4 is greater than the remaining total.
Therefore, set the 4’s bit to 0.

g) 2 is greater than the remaining total.
Therefore, set the 2’s bit to 0.

h) As the remaining value is equivalent to l’s bit, set it to 1.
1 – 1 = 0
Conversion is complete 65₁₀ = (1000001)₂

Example:
The conversion steps can be given as follows:
Given Number : 65
Equivalent or value less than power of 2 is : 64
(1) 65 – 64 = 1
(2) 1 – 1 = 0

65₁₀ = (1000001)₂.

Question 3.
Explain the procedure to convert fractional decimal to Binary.
Answer:
The method of repeated multiplication by 2 has to be used to convert such kind of decimal fractions. The steps involved in the method of repeated multiplication by 2:

Step 1: Multiply the decimal fraction by 2 and note the integer part. The integer part is either 0 or 1.

Step 2: Discard the integer part of the previous product. Multiply the fractional part of the previous product by 2. Repeat Step 1 until the same fraction repeats or terminates (0).

Step 3: The resulting integer part forms a sequence of Os and Is that become the binary equivalent of decimal fraction.

Step 4: The final answer is to be written from first integer part obtained till the last integer part obtained.

Integer part

Write the integer parts from top to bottom to obtain the equivalent fractional binary number. Hence (0.2)₁₀ = (0.00110011…)₂ = 0.00110011)₂

Question 4.
How will you convert Binary to Decimal?
Answer:
To convert Binary to Decimal we can use positional notation method.

• Step 1: Write down the Binary digits and list the powers of 2 from right to left (Positional Notation)
• Step 2: For each positional notation written for the digit, now write the equivalent weight.
• Step 3: Multiply each digit with its corresponding weight
• Step 4: Add all the values.

Example:
Convert (111011)₂ into its equivalent decimal number.

32 + 16 + 8 + 0 + 2 + 1 = (59)₁₀
(111011)₂ = (59)₁₀

Question 5.
How will you convert Binary to Octal?
Answer:

• Step 1: Group the given binary number into 3 bits from right to left.
• Step 2: You can add preceding 0 to make a group of 3 bits if the left most group has less than 3 bits.
• Step 3: Convert equivalent octal value using “2’s power positional weight method”

Example:
Convert (11010110)₂ into octal equivalent number

Step 1: Group the given number into 3 bits from right to left.

The left most groups have less than 3 bits, so 0 is added to its left to make a group of 3 bits.

Step 2: Find Octal equivalent of each group.

Question 6.
Give the procedure to convert Binary to Hexadecimal.
Answer:

• Step 1: Group the given number into 4 bits from right to left.
• Step 2: You can add preceding 0’s to make a group of 4 bits if the left most group has less than 4 bits.
• Step 3: Convert equivalent Hexadecimal value using “2’s power positional weight method”.

Example
Convert (1111010110)₂ into Hexadecimal number

Step 1: Group the given number into 4 bits from right to left.

0’s are added to the left most group to make it a group of 4 bits.

Question 7.
Give the procedure to convert fractional Binary to Decimal equivalent.
Answer:
The steps to convert fractional Binary number to its Decimal equivalent:
Step 1 : Convert integral part of Binary to Decimal equivalent using positional notation method.

Step 2 : To convert the fractional part of binary to its decimal equivalent.

• Write down the Binary digits in the fractional part.
• For all the digits write powers of 2 from left to right starting from 2^-1, 2^-2, 2^-3 ….. 2^-n, now write the equivalent weight.
• Multiply each digit with its corresponding weight.
• Add all the values which you obtained in Step 2.3.

Step 3 : To get final answer write the integral part (after conversion), followed by a decimal point(.) and the answer arrived at Step 2.4

Example:
Convert the given Binary number (11.011)₂ into its decimal equivalent Integer part (11)₂ = 3

Question 8.
Explain the method of represent signed binary number in Signed Magnitude representation.
Answer:
The value of the whole numbers can be determined by the sign used before it. If the number has ‘+’ sign or no sign it will be considered as positive. If the number has sign it will be considered as negative.

Example:

1. + 43 or 43 is a positive number
2. – 43 is a negative number

In signed binary representation, the left most bit is considered as sign bit. If this bit is 0, it is a positive number and if it 1, it is a negative number. Therefore a signed binary number has 8 bits, only 7 bits used for storing values (magnitude) and the 1 bit is used for sign.

1. +43 is represented in memory as follows:

2. -43 can be represented in memory as follows.

Question 9.
Explain the method of represent signed binary number in l’s complement representation.
Answer:
This is an easier approach to represent signed numbers. This is for negative numbers only i.e. the number whose MSB is 1.
The steps to be followed to find l’s complement of a number:

• Step 1 : Convert given Decimal number into Binary
• Step 2 : Check if the binary number contains 8 bits, if less add 0 at the left most bit, to make it as 8 bits.
• Step 3 : Invert all bits (i.e. Change 1 as 0 and 0 as 1)
  Example: Find l’s complement for (-24)₁₀
  

Question 10.
Explain the method of represent signed binary number in 2’s complement representation.
Answer:
The 2’s-complement method for negative number is as follows:
a) Invert all the bits in the binary sequence (i.e., change every 0 to 1 and every 1 to 0 i.e., 1’s complement)

b) Add 1 to the result to the Least Significant Bit (LSB).
Example:
2’s Complement represent of (-24)₁₀

Question 11.
Explain binary addition with suitable example.
Answer:
The following table is useful when adding two binary numbers.

In 1 + 1 = 10, is considered as sum 0 and the 1 as carry bit. This carry bit is added with the previous position of the bit pattern.

Example: Add: 1011₂ + 1001₂

Step 1 : Convert 23 and 12 into binary from

Step 2: Binary addition of 23 and 12:

Question 11.
Explain binary subtraction with suitable example.
Answer:
The table for Binary Subtraction is as follows:

When subtracting 1 from 0, borrow 1 from the next Most Significant Bit, when borrowing from the next Most Significant Bit, if it is 1, replace it with 0. If the next Most Significant Bit is 0, you must borrow from a more significant bit that contains 1 and replace it with 0 and 0s upto that point become Is.

Example : Subtract 1001010₂ – 10100₂.

Example : Perform Binary addition for the following:
(-21)₁₀ + (5)₁₀

Step 1 :
Convert – 21 and 5 into binary form

Step 2 :

Step 3 :
Binary Addition of – 21 and 5 :

A slide master is a slide that is used as the starting point for other slides. It is similar to a page style in Writer. It controls the basic formatting of all slides based on it. A slide show can have more than one slide master.

A slide master has a defined set of characteristics, including the background color, graphic, or gradient; objects in the background; headers and footers; placement and size,of text frames, and the formatting of text.

All of the characteristics of slide masters are controlled by -styles. The styles of any new slide you create are inherited from the slide master from whom it was created.

Changing a style in a slide master result in changes to all the slides based on that slide master.

It is, however, possible to modify each individual slide without affecting the slide master.
