XPHow e-mail works
• E-mail is a way of sending an electronic letter.• An electronic letter is called an e-mail message.• E-mail messages can be delivered in minutes and
the same message can be sent to multiple people.• The computer and software you use to send
messages is called an e-mail system.• The “post office” that receives and sends the
messages to the correct address is called an e-mail server.

XPHow e-mail works
• E-mail server software is used by the e-mail server to create an electronic mailbox for each person.
• The e-mail server sorts and sends messages to other e-mail servers to deliver e-mail to the correct person.
• To use e-mail, you must have e-mail client software and an account with an e-mail server company.

XPHow e-mail works
• Microsoft Outlook Express (among others) is an e-mail client software package and can manage your e-mail.
• The way e-mail is handled is called a store-and-forward technology. – E-mail server stores messages in your mailbox
– You sign on and request your mail
– The e-mail server forwards your mail to your PC

XPUsing attachments
• E-mail systems handles only unformatted text files.
• You can send formatted text, graphics or virtually any file format by sending it along with an e-mail as an e-mail attachment.
• The receiver of the e-mail can open the attachment if the receiving PC has software that can handle the attachment’s format.

XPSize Limits for Messages and Attachments
• Some e-mail systems place limits on messages and attachments.
• You should try to keep the size less than 1 MB.• Zip or compression technology can reduce the size
of the file before sending it.• The amount of compression depends on the file
type.• WinZip is a typical zip/unzip software package.

XPSmileys, Flame Wars and Spams
• E-mail has it’s own shorthand, including a whole array of emoticons or smileys indicating a smile or frown or other emotion.
• There are many other protocols – like typing in all capitals – the equivalent of shouting.
• You can get easily caught up in a flame war – resulting from a series of increasingly nasty or insulting messages flying back and forth.
Practical PC, 3eChapter 9
14
XPSmileys, Flame Wars and Spams
• The unwritten code of ethics governing e-mail is called netiguette.
• Flame wars are rude and unproductive use of the Internet.
• Spam mail – unsolicited junk e-mail – is also a bad and irritating use of e-mail.
Practical PC, 3eChapter 9
15
XPSmileys, Flame Wars and Spams
• Correct netiguette to follow:– Read and respond to e-mail promptly
– Check your grammar and spelling
– Think before you send a negative or irritating message
– Use smileys to help convey your message
– Don’t reply to all if your message is just to the sender
– Don’t send unnecessary e-mail
– Use Zip to shrink the size of your attachments when appropriate

XPHardware – Local Area Networks
• Many businesses connect their office PCs to each other and the Internet by using a Local Area Network (LAN).
• This connection is always available.• The LAN can provide shared access to many
resources such as software, files, printers and the Internet.
Practical PC, 3eChapter 9
18
XPHardware – Local Area Networks
• The key elements of a LAN are:– Workstations – usually standard PCs, connected to a
LAN for sharing resources
– A network server – a computer that helps control the resources and provide services to the workstations
– A file server to store data files or software
– A print server to control the attached printers
– An e-mail server to control the mail services
– A hub to connect all of the other devices

XPHardware – Local Area Networks
• LANs usually require a network specialist to install and maintain them.
• For a PC or laptop to connect to a LAN, it must have a network interface card (NIC) – Desktops are connected using a 10Base-T or coaxial
cable
– Notebook computers use PCMCIA cards for easy removal

XPHardware – Local Area Networks
• When you sign onto a LAN, you will need a userid/password to identify yourself.
• The sign on process usually includes a login script to connect you to the network.
• The My Network Places icon (or Network Neighborhood) gives you an overview of the entire network.

XPWhat do you think?
Just how private is e-mail?
1. Do you think most people believe that their e-mail is private?
2. Do you agree with CalTech’s decision to expel the student who was accused of sending harassing e-mail to another student?
3. Do you think that e-mail should have the same privacy protections as telephone conversations and mail under U.S. laws?
