इंटरनेटवरून माहितीची देवाणघेवाण करण्यात येणाऱ्या विविध प्रणाली खाली दिल्या आहेत. सर्वसाधारणपणे कोणत्या प्रणालींमधून माहितीचे वहन सर्वात जलद होते ?
अ. HTTP
ब. TCP
क. FTP
ड. DHCP
इ. UDP
फ. NNTP
ग. IMAP
h. RSVP
योग्य पर्याय निवडा :

The correct answer is Option B (b, c, e, a).

Key Points:
• Core Transport and Application Layer Protocols:
• UDP (User Datagram Protocol - e): A connectionless, lightweight transport protocol offering maximum transmission speed due to zero handshaking or retransmission latency, making it standard for real-time streaming.
• TCP (Transmission Control Protocol - b): The primary connection-oriented, flow-controlled transport layer mechanism underpinning low-overhead reliable internet streams.
• FTP (File Transfer Protocol - c): Uses dedicated dual channels (port 20 for data and 21 for control) optimized specifically for high-throughput binary file transfers.
• HTTP (Hypertext Transfer Protocol - a): The fundamental, optimized application standard powering rapid worldwide web document delivery.
• Protocols such as IMAP, DHCP, NNTP, and RSVP carry transaction, routing, reservation, or authentication overheads not designated for bulk raw data conveyance.
• Therefore, the combination b, c, e, and a contains the recognized high-performance data transfer protocols (Option 2).
• Key Takeaway: The premier high-speed transport and delivery protocols for online data streams are UDP, TCP, FTP, and HTTP.
