Using quotation marks around search queries helps in effective searching in following ways:
- Quotation mark is used around a phrase or search terms. It limits the search results to only those Web pages that contain the exact phrase, that has been specified.
- Using quotation marks ensures that, the phrase or query will be searched for as a whole and not picked apart by the search engine. Without the quotation marks, the results will include any page that contains the individual words we have used regardless of the order of the words.
- For example typing Computer Network without quotation marks could potentially retrieve all items that mention Computer, all items that mention Network as well as the items about Computer Network. This could lead to results that seem to have nothing to do with our topic. For best results, we should write “Computer Network”.
Question 7.
Fatima is a school owner and wants an internet connection for the computer lab of her school. Explain her the various ways to connect with the internet. (3)
Answer:
There are mainly three ways of connecting to the Internet, which are as follows:

It serves as the data transfer medium. User needs to enter the password and specify a username at the time of initiating the connection. A dial¬up connection is the least expensive way to access the Internet, but it also slowest connection.
2. Broadband connection: Broadband refers to high speed data communication that uses various high-capacity transmission technologies to transmit data, voice, and video across long distances. Common mediums of transmission include coaxial cable, fiber optic cable, and radio waves. Broadband removes the need for dial-up as it is always connected.
Wireless connection: Rather than physically connecting devices with cables, wireless networking is a method of transferring data between computers and others networking devices using radio frequency waves. For wireless connectivity computers requires a wireless adaptor. WiFi, WiMAX and LTE are different methods of wireless connection.
