Communication Methods : Post

The traditional postal system can be used to deliver letters and parcels to almost anywhere in the world. This is because a postal system is simple to operate and requires virtually no modern technology to function.

An address written on a package is used to identify the destination to which it should be delivered. Most countries include a code such as a postcode in the address. This identifies the area that the package is to be delivered to. If a computerised sorting system is available then this will use the code to automatically route a package to its destination. The last stage of delivery is carried out by a postman who takes the package to the house that it is addressed to.

The cost of sending a package is paid for by purchasing stamps which are stuck onto the packet. It is more expensive to send heavier packages. It also costs more to get a package delivered more quickly.

Advantages
  1. The postal system is universal. Almost anyone, anywhere in the world can send and receive a package.
  2. Parcels can be sent in the post.
Disadvantages
  1. It can take a long time to send a package in the post, especially if it has to be sent a long way. For this reason post is sometimes referred to as "snail mail". A letter sent within the UK can usually be delivered the day after it is sent.
