- Working from home is known as teleworking. We are able to do this due to the advancements of technology and the internet. You are able to work from home if you have a phone, a computer and internet connection. This saves on travelling and other issues. 15,000 out off the 35,000 staff in HSBC bank have the ability to work from home due to the internet.
- The internet has allowed for shopping to be carried out 24/7 as only a computer and internet connection are needed to purchase items online. So unlike in a shop, customers are able to purchase items at any time of the day. Online deliveries are widely available for nearly every shopping website. The improved security such as the introduction of PayPal which is a very secure online payment method has contributed to customers feeling safe about paying online, therefore increasing the number of buyers who purchase goods online. There are also data tracking services which track the journey of your ordered item so you are able to know where it is and when it will come to you.
