If you want to have general information about any subject, like India’s freedom struggle Movement or Mar’s Mission, Internet is the best option. The Internet and World Wide Web has made it easy for anyone to access information.
A Web directory organizes Websites by subject, and is usually maintained by humans instead of software. The searcher looks at sites organized in a series of categories and menus. Directories are collections of Internet sites organized by subject. Users click on a topic of interest, and then browse through the list of resources in that category.

Searching for pictures

There are many websites that allow the user to search for pictures, sounds, video clips, etc. from Internet. Let us use google.com to search for pictures and images on any topic.
Follow these steps:
Open the website www.google.com.
Type the topic ‘Mahatma Gandhi’ in the search box. Click on Images tag.
Click on ‘Search Images’ button.
The search results appear on the screen.
Choose the picture and click on it to see the enlarged view.
For copying the picture on your computer, right click on it and select Save Image As …. or Save Picture As… option from the sub-menu.
The ‘Save Picture’ dialog box appears. Choose the location where you want to save, enter the file name, and click on ‘Save’ button.

Tips for Smart Searching

Type the keyword in the search box, then click the Search button.
If you type more than one word, they are automatically connected with AND. (For example: sun moon = sun AND moon).
Connect your keywords with OR to find all pages with either one word or the other, or both. (For example: boys OR girls. This will find all pages that mention boys or girls or both.)

Put inverted commas around a phrase if you want to find those exact words in that order. (For example: “sun is a ball of fire.” If you don’t use the comma, each word in the phrase will be searched separately, and you will get a lot of unwanted results.
Use the asterisk (*) to look for words with the same stem. (For example: type disease * to find disease, diseases, diseased.
Use ‘#’ sign, where you are not sure of exact spellings. For example m#n will retrieve man or men.
