2 questionsCase Study 1
Mary has a prepaid Internet plan. She has a data limit of 14 GB. The average size of an E-mail with an attachment that Mary downloads is 1.4 MB.
Answer the questions given below.
(i) Approximately, how many E-mails can Mary download without exceeding her data limit?
(ii) What is E-mail?
(iii) Mary's friend is not able to understand the term attachment in E-mail. Help her to know this.
(iv) Name any two website who provide E-mail services.
Answer:
(i) Data limit of Mary is 14 GB and 1 GB = 1024 MB.
Thus, 14 GB = 1024 x 14 = 14,336 MB
The average size of an email with attachment is 1.4 MB.
To find out the number of emails Mary can download without exceeding her data limit, we need to divide her data limit by the average size of an email with an attachment:
Number of Emails = Data Limit / Average Size of Email
Number of Emails = 14,336 / 1.4
Number of Emails = 10,240
Therefore, Mary can download approximately 10,240 emails without exceeding her data limit.
(ii) E-mail is the most widely used tool to send and receive electronic messages between users over a network such as the Internet.
(iii) Attachments refer to files or documents that are included with an email message. These files can be of various types, such as documents, images, spreadsheets, or any other file format that can be attached to an email.

(ii) How is data flow secured in SSL?
(iii) Write two advantages of SSL.
(iv) Name the protocol used for secure login into a remote computer system.
Answer:
(i) SSL (Secure Sockets Layer) is a standard security protocol which ensures data security by establishing encrypted online links between a web server and a browser. It encrypts the transmitted data and keeps it secure.
(ii) SSL uses encryption algorithms to scramble data during transit. It provides a way for the user's browser to verify the identity of the server and ensures that the data transferred between the user and the server remains intact and has not been tampered with during transit. Data is decrypted before it can be used by the receiving system.
(iii) Two advantages of SSL are:
- SSL provides a secure and encrypted connection, protecting sensitive information from unauthorized access and ensuring the confidentiality of data.
- SSL provides the means for establishing the authenticity of the websites we are connecting to.
(iv) SSH (Secure SHell).
