This includes why we communicate using email and how we are able to shop online from the comfort of our own homes. </li></ul>
  3. 3. E-mail <ul><li>Electronic mail is a form of communication where text based messages are exchanged between people by using computers attached to a network </li></ul>
  4. 4. Email <ul><li>In order to use email the following things are needed: </li></ul><ul><li>The sender and recipient need an email address which will be provided by an e-mail service such as Microsoft Hotmail, Google mail, Eircon etc. </li></ul><ul><li>Both parties need access a computer or device which can send and receive emails </li></ul><ul><li>Both parties need access to email software such as Microsoft Outlook </li></ul><ul><li>Messages sent from one person will be sent to the 'mailbox' of the recipient.

  5. 5. Uses of Email <ul><li>There are lots of reasons why email is so commonly used.

  7. 7. Email - pros and cons <ul><li>Disadvantages </li></ul><ul><li>Both you and the person receiving the email must have an email address and access to a computer and the Internet </li></ul><ul><li>If you don't know the email address of the other person then you can't send them a message </li></ul><ul><li>Some people change their email addresses fairly often as they switch ISPs or jobs </li></ul><ul><li>Email attachments can contain viruses </li></ul><ul><li>Some companies won't allow email attachments to be received </li></ul><ul><li>Spam is a big problem, up to two-thirds of mails sent are spam </li></ul><ul><li>People can waste company time at work by sending emails to friends instead of working </li></ul><ul><li>When you are on holiday, your email box can become full and extra messages might not get stored </li></ul><ul><li>You may have to wait a long time to get a reply </li></ul>
  8. 8. Ecommerce <ul><li>Not that long ago if you wanted to buy something then you would have to go to the local shops. If they didn't have what you wanted then you would either have to do without or buy a substitute. </li></ul><ul><li>With the development of the Internet a phenomenon known as 'electronic commerce' or 'ecommerce' for short, has been growing. </li></ul><ul><li>Ecommerce has now grown to such an extent that it is starting to become the way to shop for many people. </li></ul>
  9. 9. What is ecommerce? <ul><li>Ecommerce means the sale and purchase of goods and services over electronic systems such as the internet. </li></ul><ul><li>This can mean businesses selling to customers or businesses selling to other businesses or a new trend with the growth of sites like ebay, ordinary people selling to other people. </li></ul><ul><li>Although ecommerce tends to be thought of mainly to do with shops it actually covers a whole range of other things. It can also be things like ordering concert tickets online, booking a last minute holiday, reserving and paying for a movie at your local video store. </li></ul><ul><li>Some ecommerce is entirely electronic from start to finish, for example paying for access to premium content on a website. There are no physical items involved. </li></ul><ul><li>But for most people, ecommerce does involve physical goods </li></ul>
  10. 10. What can you buy? Almost anything that you could think about is now available for purchase using ecommerce. Here are a few examples. Thickets for a concert Air line travel tickets Book a hotel uk Books, Music, CD,s
  11. 11. How do you buy something? <ul><li>In order to purchase something using ecommerce you will need access to the internet. This can be using a computer, a PDA, a mobile phone etc. </li></ul><ul><li>You then need to find the site from which you wish to buy an item. This might involve going straight to a particular site or browsing through a number of sites until you have made your decision. </li></ul><ul><li>Once you have chosen an item you 'add it to your basket'. This acts like an electronic shopping basket and it keeps a record of all of the things that you intend to buy. This means that you can choose one item and then continue shopping for more. </li></ul>
  12. 12. <ul><li>Once you have chosen all of your items, you will 'proceed to the checkout'. This is where you will pay for your goods. </li></ul><ul><li>However before you can pay, you need to tell the company who you are. If this is the first time that you have visited the site then you will need to create an account for yourself. This involves filling in a form with your name, address, telephone number, email address and then choosing a user name and password. </li></ul><ul><li>Each time you revisit the site to buy more items, you log in using your user name and password and the site (through the use of cookies) will remember who you are and will already have your name and address stored. </li></ul>How do you buy something?
  13. 13. <ul><li>Once you have created an account or logged in, then you can continue through the checkout process. You need to confirm your order and then enter details of how you wish to pay. If you are going to use a credit card then you need to enter the details on the card. If you have used this site before then it will remember these details for you also. </li></ul>How do you buy something?
  14. 14. <ul><li>Once you have paid for your goods you will get an electronic confirmation on the screen that your order has been accepted. You will usually also get a confirmation via email. This acts as a security measure in case someone got hold of your user name and password and tried to buy goods by pretending to be you. By sending you a separate email, this would alert you that something wasn't right. </li></ul><ul><li>Your order is then processed by the ecommerce store and sent to you by post. You usually need to be at home in order to receive your parcel. </li></ul><ul><li>If you are not happy with the items that you have bought then you have the right to return them just like you would if you bought something from a store in town. </li></ul>How do you buy something?
