CBSE Class 7 Computer Science Question Paper Set 06 with Solutions

Answer: (b) src. The src (source) attribute of the <img> tag gives the file name and path of the image.

Teacher's Note:
1. img is the tag itself, while src is its attribute.
2. Do not confuse a tag with an attribute.

Answer: (b) Internal. An internal link connects one page of a website to another page of the same website.

Teacher's Note:
1. An external link goes to a different website.
2. Think of internal as 'inside the same site'.

Answer: (b) rowspan. rowspan merges cells vertically, that is, across rows of the same column.

Teacher's Note:
1. colspan merges cells across columns (horizontally), while rowspan merges them down rows (vertically).
2. Read the question carefully for the direction of merging.

Answer: (c) Assignment. The = operator stores a value in a variable, e.g. x = 5.

Teacher's Note:
1. Assignment uses a single =, which is different from == used for comparing.
2. Arithmetic operators calculate and logical operators combine conditions.

Answer: (a) sequential. In a sequential structure, statements run one after another in the order they are written.

Teacher's Note:
1. Branching chooses between paths, while sequence has no choice.
2. Most simple programs are mainly sequential.

Answer: (a) case sensitive. In Python, Name and name are two different identifiers.

Teacher's Note:
1. print works but Print gives an error in Python.
2. Keep the same capital and small letters when using variable names.

Answer: False. An image can be added with the <img src="..."> tag, and it can also be made a link by placing it inside an <a> tag.

Teacher's Note:
1. The <img> tag is used to add images.
2. An image placed between <a> and </a> becomes clickable.

Answer: False. The width and height attributes (in pixels or percent) set the size of a table.

Teacher's Note:
1. Size is set with attributes like width and height.
2. Percent values make the table adjust to the screen.

Answer: False. href stands for hypertext reference; it holds the address (URL) of the link target.

Teacher's Note:
1. href is used in the anchor tag <a>.
2. Remember it as hypertext reference.

Answer: True. if…else adds an else block that runs when the condition is false.

Teacher's Note:
1. Simple if runs code only when the condition is true.
2. if…else gives a second path for the false case.

Answer: True. if-elif-else tests several conditions one by one and runs the block of the first true one, otherwise the else block.

Teacher's Note:
1. Use it when there are more than two possible outcomes.
2. Only one block of the chain runs.

Answer: True. Python uses indentation (spaces at the start of lines) to show which statements belong to a block.

Teacher's Note:
1. Python does not use curly braces for blocks.
2. Wrong indentation causes an IndentationError.

Answer: False. HTML is not case sensitive; <B> and <b> work the same way.

Teacher's Note:
1. Python is case sensitive, but HTML is not.
2. Writing tags in lower case is still good practice.

Answer: cellpadding. Cellpadding is the space between a cell's content and its border.

Teacher's Note:
1. Cellspacing is the space between two cells, not inside a cell.
2. Padding means the space inside, next to the content.

Answer: relative. A relative path gives the location of the file with respect to the current page.

Teacher's Note:
1. A relative path is short, e.g. pages/about.html.
2. Absolute path gives the complete address of the file.

Answer: absolute. An absolute path gives the full location or complete address of the file.

Teacher's Note:
1. Absolute means the complete path from the root or the full URL.
2. Relative and absolute are the two types of paths.

Answer: <img> (image tag). It is an empty tag that places a picture on the page.

Teacher's Note:
1. It has no closing tag.
2. It must be used with the src attribute.

Answer: if. The statement starts with the keyword if.

Teacher's Note:
1. The keyword is written in lower case.
2. Python statements start with keywords like if, elif and else.

Answer: condition (a test that is either True or False), for example if age >= 18:

Teacher's Note:
1. The condition is usually a comparison.
2. The block runs only if the condition is True.

Answer: colon (:). The colon marks the end of the if line, and the indented block follows it.

Teacher's Note:
1. Forgetting the colon gives a SyntaxError.
2. The lines after the colon must be indented.

Answer: The assignment operator (=) is used to store a value in a variable. Example: x = 10 stores 10 in x.

Teacher's Note:
1. Give a one-line definition with an example.
2. Do not confuse = with ==.

Answer: Logical operators (and, or, not) combine or reverse conditions and give a result of True or False. Example: (a > 5) and (b < 10).

Teacher's Note:
1. Name all three: and, or, not.
2. They are mostly used in if conditions.

Answer: Cell spanning means merging two or more table cells into one large cell using the colspan attribute (across columns) or the rowspan attribute (across rows).

Teacher's Note:
1. Mention both colspan and rowspan.
2. Spanning merges cells, whereas spacing only adds gaps.

Answer: Cell spacing (the cellspacing attribute) is the space between two adjacent cells of a table.

Teacher's Note:
1. Cellspacing is outside the cells, between them.
2. Cellpadding is inside a cell.

Answer: 1. Bulleted list uses the <ul> (unordered list) tag; items are shown with bullet symbols and have no order.
2. Numbered list uses the <ol> (ordered list) tag; items are shown with numbers or letters in sequence.
3. In both, each item is written with the <li> tag.

Teacher's Note:
1. Use ul for bullets and ol for numbers.
2. Give the tag names and a point each on the display.

Answer: Purpose: A table displays data in rows and columns in an organised way, so it is easy to read and compare. It is also used to arrange text and images on a web page.
Attributes of the <table> tag:
1. border: sets the thickness of the table border.
2. width and height: set the size of the table.
3. cellpadding: space between cell content and cell border.
4. cellspacing: space between cells.
5. align and bgcolor: set alignment and background colour.
(colspan and rowspan are attributes of the cell tags <td>/<th> used to merge cells.)

Teacher's Note:
1. Name the purpose first, then list at least four attributes.
2. Remember that the tags <tr>, <th> and <td> make rows, headings and data cells.

Answer: Option 1: if-else statement
It is a decision-making statement that runs one block of code if the condition is True and another block if the condition is False.
Syntax:
if condition:
    statement(s) # runs when the condition is True
else:
    statement(s) # runs when the condition is False
OR Option 2: Even or odd program
num = int(input("Enter a number: "))
if num % 2 == 0:
    print(num, "is even")
else:
    print(num, "is odd")

Teacher's Note:
1. Attempt only one of the two options; indent the blocks and do not forget the colons.
2. A number is even when the remainder on dividing by 2 is 0, checked with the % operator.
