While both the abstract and the synopsis provide a summary of the thesis's contents, the synopsis is far more in-depth and comprehensive than the abstract. The abstract of the thesis may be included in the synopsis as well, depending on the requirements of the institution.

The abstract of a thesis is a short synopsis of the whole paper and is often placed at the beginning. It tells the reader what the thesis is about and summarizes the important topics discussed throughout. In contrast, a thesis abstract is a brief overview of the complete thesis and is often appended at the conclusion. The abstract expands on the thesis's introduction by summarizing the study's key arguments and conclusions. While both the abstract and summary play a vital role in assisting readers in comprehending the thesis's content, they do it in distinct ways and with varying degrees of information. Assuming you have collected enough data to go on with writing your thesis, here is some guidance I can provide. 

Also, I'm assuming that your thesis defense is scheduled for the near future and that your advisor has requested you to submit your work before then.
 

1. Plan your defense of your thesis or dissertation a good six to eight months in advance. You'll have plenty of time to plan out your work and get started writing.
2. I insist that my pupils make it a routine to record their results in writing. If you aren't already using LaTeX, you should start. Take it from me, this will simplify things for you. LaTeX is the way to go if you need to include a lot of equations in your work. LaTeX is a powerful tool for managing your chapters and figures, and it is extremely useful for organizing figures and citations. Get started on your thesis by sketching out a basic outline of the sections and subsections it will include. Create rough drafts of your thesis's chapters in accordance with your institution's guidelines.
3. Finish the first chapter (the prologue) last.
4.) The time it takes to write a normal thesis may range from one to three months, depending on the depth of your study and the amount of free time you have. Every day, I would commit at least five or six hours. The best strategy is to get started right away and maintain the habit of producing some kind of brief report after each experiment or after each set of research results. You won't forget anything crucial about any trial, and your study will remain neatly organized.
Your thesis should be organized in a way that reads like a tale. 

 

The typical progression of a thesis looks like this:
 

Page 1 Title
Title page requesting clearance from the Thesis Committee.
Acknowledgement
Overview of the Contents
Definitions of Symbols (List of Abbreviations)
Figures List
Tables List
Any and all Algorithm Lists
Introductory Chapter
Section: Context and Analysis of Recent Literature
Based on the scope of your project and the results you obtain, your research methodology might span many chapters. Make use of subheadings and subchapters to organize your work, but ensure that each succeeding chapter builds upon its predecessor.
Experiments and Results from the Research
Discussion Chapter
Section: Final Thoughts and Further Developments
Bibliography
Optional Appendices
 

Begin writing each chapter, and when you complete them, submit them to your supervisor for feedback. This will save him time and effort since he will be able to fix it and provide you with feedback more quickly. Also, inform them of any changes you make. Each line of the manuscript chapters should be numbered before submission. You'll be able to use it as a guide for tweaking the right places. It's useful for email correspondence as well (e.g., "please update line ## on page ## to read "so and so instead of so and so").
 

Create several copies of your thesis data backups. I recommend giving them names like YourName_ThesisDraft_ver_#, etc. To the _ver_#, please add all new chapters. This way, all of your drafts will be in order and you can easily access them at any time. Always have a copy stored online (such as in Dropbox, Google Drive, etc.). USB memory sticks might suddenly fail at any time.
Make sure you utilize high-resolution photos or graphs for point No. 8. For charts and graphs, you should use.eps or vector graphics at a resolution of at least 300 dpi. Maintain order by labeling each section. Name them creatively to minimize repetition. You should include figures within two pages of where you refer to them, preferably at the top or bottom of the page. Reviewers should not have to flip through many pages to locate this data.
 

If you're using a photo or figure from someone else's work, be sure to properly credit them. Steer clear of even accidental instances of plagiarism.
After you've written all the chapters, look them over carefully to check for grammar mistakes.

Allow yourself a fair amount of time (15-20 days) to double-check your work before turning it in. Get your coworkers to look it over if you can. Quite often, there is something we fail to see that may be uncovered by others.
Be consistent with the thesis's typeface throughout. Inconsistencies in font style are particularly distracting to the reader.
