Which bandwidth is used for direct communication between very high-speed computers (like mainframes)?

Explanation

Baseband for Direct, High-Speed ConnectionsBaseband transmission refers to a method where the data signal occupies the entire bandwidth of the communication channel. This allows for high-speed data transmission with minimal distortion, making it suitable for direct connections between high-speed computers like mainframes. In baseband transmission, the data signal itself is transmitted without any modulation onto a carrier signal. This avoids the complexities of modulation and demodulation required in other communication methods.Here's an analogy: Imagine a highway with multiple lanes. In baseband communication, all the lanes are dedicated to a single high-speed data stream, allowing for maximum throughput between the two computers.
