The thing at the begining is called the introduction. If you want a thesis with a topic on computer you need to make it interesting it needs to catch the readers attention here is an example.... It Knows everything it has all the answers. I wonder if there is anything it doesn't know. It seems to be the smartest thing in the world. Do you know what it is yet? A computer! - Something like that include the reader.... the thesis goes in the introduction it should be the first couple of sentences of the introduction . Also a thesis includes that in your introduction you need to state your point and tell what you are going to talk about in your body. For the body you need three paragraphs in these paragraphs you need to support what you are writing about... you need to use LOTS of detials. You can start off you paragraphs with first(only for the first paragraph in the body), next ,secondly(only for your 2 paragraph in the body), last but not least, (only for your 3rd paragraph in the body), finally...things like that. at the conclusion NEVER say inconclusion.... just sum up what you said in the introduction... you need to sort of repeat what you said in the first paragraph but instead of it being the introduction it need to have sense of completeness so you would need to sum up your point. Some other tips are dont repeat the same(or alike) sentences in paragraph use variety... also use good words go into good detail for example dont use the word stuff or things go into detail on what those "things" are or what that "stuff" is. instead of using the word big use gigantic or massive (use bigger words).
