10 multiple-choice questions written against this chapter, each with its answer and the reason. Try one before you open the answer.
Question 1
What does HTTP stand for?
Answer: A HyperText Transfer Protocol
Why
HTTP is the set of rules that web browsers and web servers use to talk to each other. Its full name is HyperText Transfer Protocol. HTML is the language used to create webpages, so it is not the answer.
Question 2
The Web runs on which network?
Answer: A The Internet
Why
The textbook says the Internet is a network of networks that the Web runs on. The Web is one of the services of the Internet, and the most popular one.
Question 3
Which software do users use to view webpages?
Answer: A Web browser
Why
A web browser is the software that users use to view webpages. A web server stores webpages and answers requests. HTTP is a set of rules, and HTML is a language, so neither one is software that users open to view pages.
Question 4
Which file extension is used for HTML documents?
Answer: A .html
Why
HTML documents are saved with a .html extension. For example, home.html is a valid file name for a webpage.
Question 5
Which HTML element inserts a new line?
Answer: A br element
Why
The br element inserts a new line. It is a void element, so it has no end tag. The p element makes a paragraph, h1 makes a heading, and b makes bold text.
Question 6
In an anchor tag, what does the value _blank of the target attribute do?
Answer: B Shows the linked page in a separate window or tab
Why
The value _blank displays the webpage in a separate window or tab. The value _self is the default, and it shows the page in the same window or tab.
Question 7
In an HTML table, how is the number of rows decided?
Answer: A By the number of tr elements in the table
Why
The number of rows is set by the number of tr elements inside the table. The number of columns is set by the number of td elements in each row.
Question 8
In an ordered list, the type attribute is set to i. Which numbering appears in the list?
Answer: A Lower-case Roman numerals (i, ii, iii)
Why
In the type attribute for ordered lists, i means lower-case Roman numerals. The capital I would give upper-case Roman numerals. The lower-case letter for the English alphabet is a, and Arabic numerals are the default.
Question 9
Which of these is a relative URL?
Answer: A somedirectory/somefile.html
Why
A relative URL is a path given relative to the location of the current webpage, such as somedirectory/somefile.html. The other three are absolute URLs, because each one includes the protocol, such as http or https, and the host name.
Question 10
A row in an HTML table has four td elements. One of them has colspan=2 and the other three do not. How many columns does this row cover?
Answer: B 5
Why
The colspan=2 cell covers two columns. The other three cells cover one column each. So the total is 2 + 1 + 1 + 1 = 5 columns. The colspan attribute merges columns, so one cell can cover more than one column.
