B it is b..............................................
Didn’t you just make a question right now?
It was quite difficult to understand what you need. Anyway, I've got it. I guess you need to much all the terms to each sentence. So I think I've done it right. Check it out:
1.an electronic index of books - <span>B. computer catalog
</span><span>
2.a device which categorizes and locates web sites - </span><span>H. search engine
</span><span>
3.to draw a conclusion - </span>D. infer<span>
4.a block of information stored in an HTML file on a server - </span><span>A. web page
</span><span>
5.the table of contents of a web site - </span><span>G. home page
</span><span>
6.a software package which retrieves information from any or all available Internet servers - </span><span>I. browser
</span><span>
7.a highlighted word or phrase within a web page which acts as a "bridge" to another web page or site - </span><span>F. hyperlink
</span><span>
8.a topic sentence - </span><span>C. key sentence
</span><span>
9.a term which aids in narrowing a web search - </span>E. keyword
You can find the components that you wanted to modify in : C. control panel
You can adjust your computer's setting through control panel, whether it's your system and security, hardware, net work setting, etc
hope this helps
