Section 1.4 exercises

EXERCISE 1 – E-mail applications

  1. Install an e-mail application on your computer or device according to the learning material and the IT Center instructions.
  2. Create an e-mail account in the application and make the required settings in the account.
  3. Log into your university e-mail. Type a test message to yourself to check whether everything works!

EXERCISE 2 – Sending messages

Many of the following exercises require installing an e-mail application according to exercise 1. If you don’t have a suitable device yourself, skip the exercises requiring the above installation.

  1. What is the difference between messages sent in plain text format and html format?
  2. Create a signature to your e-mail application.
  3. Send a message to yourself to see whether the signature shows correctly.

EXERCISE 3 – Reading messages and archiving them in folders

Only do the following exercises if you have access to a computer or a mobile device and if you have installed an e-mail application according to exercise 1.

  1. Check whether there are messages in the trash bin of your e-mail application. If there are messages which need to be deleted in the trash bin, empty the bin.
  2. Create folders for your studies, hobbies and friends in the e-mail application.

EXERCISE 4 – Processing of attachments

  1. Which file types can you send using e-mail applications?
  2. When you receive attachments, which program file types used in Windows computers contain specific risks related to use? Why?
  3. Try sending an attachment to yourself or a friend, for example (choose the file to send yourself). Check the attachment size before sending the message: if it is very large, compress the file before sending it, or consider reducing the file size by some other means (if the attachment is a photo, you can decrease the photo size, for example).

EXERCISE 5 – Sorting and searching messages

  1. Sort the messages of the Inbox folder in such a way that the oldest message is on top.
  2. Sort the messages in ascending alphabetical order by sender.
  3. Search all the messages which you have received from a specific person.

EXERCISE 6 – Junk e-mail

  1. Check the junk e-mail folder of your e-mail application (Spam, Junk or Junk Email) and make sure that no important messages have been sorted there.

 

ANSWERS

EXERCISE 2 – Sending messages

  1. A message sent as plain text does not contain the formatting options typical for html messages. A text-format e-mail takes up less storage space than an html message, however, and often works better than html messages.

EXERCISE 4 – Processing of attachments

  1. In principle, you can send any type of file. Many organisations prevent the sending or receiving of certain types of attachments, however (such file types include program files, for example).
  2. Exe, bat, com, scr, vbf and pif are especially dangerous attachment types as they may contain programs which can be executed on the computer. Note that in addition to the above mentioned file types, also many other file types are dangerous (read more about this in section 5.2).
