Hello.
I have a computer science essay assignment. I have to write about Data encryption and network security. I tried to write 2 pages and double-spaces essay, but I do not think that my sentences have correct grammar and smooth English.
Therefore, please help me to correct my grammar mistakes and to change sentences to smooth English.
Thank you!
Data Encryption and Network Security
Today most of people are exchanging information using computers. For example, the information might be a secret or very important material at a company. To protect this sort of information, many developers invented a lot of computer security and data encryption. These two have their own advantages, but disadvantages also exist.
First, there are advantages of internet security to protect against viruses or crackers. They tend to stole and eliminate our important data, but the internet security protects against them. However, the internet security has its disadvantages. For example, I was using Norton Internet Security and had a bad experience. It was very expensive, and my laptop was controlled by Norton. Also it was using many spaces of data, and my laptop was working very slowly. Therefore, I think that Norton Internet Security is not an all-purpose security.
Second, data encryption is good for protecting data that are for a company or my own data against a person who doesn’t have a key to read coded data. However, I think it is also not useful for security as Norton. For example, if I want to share very important information that is coded to my colleagues, the colleagues have to have a key to decode the coded data. Moreover, even though the data was coded, I do not think that it is never deciphered by a cracker. The movie U-571 is a good example to prove this opinion.
In conclusion, I think that Norton Internet Security and data encryption are not useful security systems. I am currently using ESET NOD32 Antivirus for network security. I got the information from my friends that this anti virus is better than Norton, so I am trying a trial one. I feel that this anti virus is not affecting other software, so my laptop is working very smooth.
