Fax

Facsimile, popularly known as fax, is a device that can send or receive a document, pictures and text over a telephone line. It is really a very wonderful machine which can transmit [প্রেরণ] any document to another day machine located within home or abroad in a very short time. It looks like a calculator-cum telephone set. Almost all modems manufactured today are capable [সক্ষম] of sending and receiving fax data. Fax/modem software generates [উৎপাদন করা] fax signals directly from disk files or the screen. Even if a document is text only, it is treated by the computer as a scanned image and is transmitted to the receiver as a bitmap. Faxing a message online works well if the recipient [প্রাপক] wants only to read the message. However, if the document requires [প্রয়োজন] editing [সম্পাদনা], it must be converted [রূপান্তর] into text by an OCR program, or it must be retyped manually into the computer. A more efficient [দক্ষ] method of sending documents that require modification [পরিবর্তন] is through the email system. Email files are already ASCII text so they can be edited immediately in any text editor or word processing program. The Internet now provides a new and cheaper way to send faxes in some cases. A number of free and commercial companies provide arrangements [ব্যবস্থা] for using the Internet rather than the public telephone system for most or part of the path to the fax point. Some services also provide the ability [ক্ষমতা] to broadcast a fax to multiple addresses. Nowadays, being practically a time saving device, it has taken the place of tele printer and is playing a vital role in international communication system.
