Writing letters on type-writers were more cumbersome in absence of computers. This is because typewriters do not possess “saving” capability unlike computers. Furthermore it also did not allow changes to be made without rubbing the contents thus making the work untidy.
Computers possess the capability of data storage whereby millions of gigabytes worth of data (thousands of documents) can be stored, Instead of the use of filing cabinets etc
Computers are very flexible in indexing and retrieval of the stored data. This feature enables us to find any file, document etc. within no time from a mountain of data.
