_ is the protocol suite for the current Internet

.A) TCP/IP

B) NCP

C) UNIX

D) ACM

The correct answer and explanation is :

Correct Answer: A) TCP/IP

Explanation:

The Transmission Control Protocol/Internet Protocol (TCP/IP) is the fundamental protocol suite that governs the functioning of the modern Internet. It serves as the standard set of communication protocols that allow devices to connect and communicate over the global network.

1. Understanding TCP/IP

TCP/IP is a layered protocol model consisting of several interconnected protocols that enable reliable data transmission across different types of networks. It was developed in the 1970s by the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA) to support robust and scalable communication.

2. Components of TCP/IP

TCP/IP consists of two main protocols:

  • Transmission Control Protocol (TCP): Ensures reliable and ordered delivery of data packets between devices.
  • Internet Protocol (IP): Responsible for addressing and routing packets across the network.

Additionally, the TCP/IP model includes four layers:

  1. Application Layer: Provides high-level services like HTTP (for web browsing), SMTP (for emails), and FTP (for file transfers).
  2. Transport Layer: Manages data transmission with TCP (reliable, connection-oriented) or UDP (faster, connectionless).
  3. Internet Layer: Handles logical addressing with IP addresses and routing using protocols like IPv4 and IPv6.
  4. Network Interface Layer: Deals with physical hardware and data transmission over different types of networks (e.g., Ethernet, Wi-Fi).

3. Why TCP/IP is the Standard Protocol Suite

  • Global Adoption: The TCP/IP model is the foundation of the Internet and is widely used in enterprise and home networks.
  • Scalability & Reliability: TCP/IP supports millions of devices globally and ensures error correction.
  • Interoperability: Works across different hardware and software platforms.

Why Other Options Are Incorrect

  • B) NCP (Network Control Protocol): Used in ARPANET (precursor to the Internet) but was replaced by TCP/IP in 1983.
  • C) UNIX: An operating system, not a communication protocol.
  • D) ACM: Refers to the Association for Computing Machinery, unrelated to network protocols.

Thus, TCP/IP remains the core protocol suite powering today’s Internet.
