The correct Answer is:
To solve the question regarding 'Facsimile Transmission (FAX)', we will analyze the options provided and determine which one accurately describes what FAX involves. ### Step 1: Understand the concept of Facsimile Transmission (FAX) Facsimile Transmission, commonly known as FAX, is a technology used to send copies of documents or images over a telephone line. It scans the document, converts it into a digital signal, and transmits it to another FAX machine, which then reproduces the document. ### Step 2: Evaluate the options 1. **Option 1: Speech Communication** - FAX does not involve speech communication. It is focused on transmitting documents, not voice. 2. **Option 2: Telegraphy** - While both FAX and telegraphy are forms of communication, telegraphy primarily deals with sending text messages using Morse code or similar methods, not document reproduction. 3. **Option 3: Exact Reproduction of a document or static picture** - This option accurately describes FAX. It is designed to reproduce documents and images exactly as they are. 4. **Option 4: Taking photograph** - FAX does not involve taking photographs. It transmits already existing documents or images rather than capturing new ones. ### Step 3: Conclusion After evaluating all the options, the correct answer is **Option 3: Exact Reproduction of a document or static picture**. This is the primary function of a FAX machine. ### Final Answer The 'Facsimile Transmission (FAX)' involves the exact reproduction of a document or static picture. ---
