## Answers

### Answer by Hitesh Vohra

- The **TCP/IP** concept, which is based on standard protocols, was designed and developed by the Department of Defense (DoD) in the 1960s. TCP/IP (Transmission Control Protocol/Internet Protocol) is the acronym for Transmission Control Protocol/Internet Protocol. TCP/IP is a simplified version of the OSI model. It has four layers, as opposed to the OSI model's seven.
- The **lowest layer,** the host-to-network layer, is concerned with the physical conveyance of data. TCP/IP does not define any protocol in particular, but it does support all of the common protocols.
- The **Internet Layer** establishes the mechanisms for logical data transmission over a network. The Internet Protocol (IP) is the principal protocol in this layer, and it is backed by the protocols ICMP, IGMP, RARP, and ARP.
- The **Transport Layer** is in charge of ensuring that data is delivered without errors from beginning to end. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are the protocols discussed here (UDP).
- The **topmost layer**, the application layer, defines the interface between host programmes and transport layer services. Telnet, DNS, HTTP, FTP, SMTP, and other high-level protocols are included in this layer.
