In a tabular form differentiate between a fax machine and a telephone
Answers
Answer:
Fax is for transmitting documents, the telephone is for speaking. They both can use a telephone line, but the device you use is different. On a telephone, you dial the number of the person you want to speak to, wait for the other.
On a fax machine, you dial the number of a fax machine where you want to send the fax message. The machine waits until the fax machine at the other end answers. Then it starts scanning the page and sends it in code to the fax machine on the other end.
After receiving the page, the remote fax machine confirms that the page has been received correctly (or not), and the sending fax machine print out this confirmation.
Because of this direct contact between both fax machines and the confirmation that the page has been correctly received on the other end, a fax transmission has a special legal status, as you have proof that the message you sent has been received well at the other end.
