Imagine you have a friend who is new to computing. He is not necessarily interested in going into programming, but he would like to know the basics in terms of how computers work, how programs are written, and how computers communicate with each other. You are talking to him about the basics, but he keeps confusing operating systems, programming language, computer language, and markup language. How would you use very plain language to explain to him the differences between these things and how they interact with each other?

i would first let him be aware that a cover letter is official and confidential and it requires a proper formatting so that the employer doesn't have hard time when going through it. he should write it in paragraphs of about two to four sentences and use proper grammar a , spelling and proper punctuation. i will also advice him not to be emotional and not also to use images.then base his attention to the details of the job described and not other things. that is he be specific to the responsibilities and to the employers requirements. on this he should make sure that the letter reflects how good he is for the requirements detailed by the employer

the letter should not be too long nor too short.
