Why is HTTP is the protocol used in World Wide Web?
As a request-response protocol, HTTP gives users a way to interact with web resources such as HTML files by transmitting hypertext messages between clients and servers. HTTP clients generally use Transmission Control Protocol (TCP) connections to communicate with servers.
What is hypertext transfer protocol used for?
Hypertext Transfer Protocol (HTTP) is an application-layer protocol for transmitting hypermedia documents, such as HTML. It was designed for communication between web browsers and web servers, but it can also be used for other purposes.
What are different types of protocols?
Types of Protocols
- Transmission Control Protocol (TCP)
- Internet Protocol (IP)
- User Datagram Protocol (UDP)
- Post office Protocol (POP)
- Simple mail transport Protocol (SMTP)
- File Transfer Protocol (FTP)
- Hyper Text Transfer Protocol (HTTP)
- Hyper Text Transfer Protocol Secure (HTTPS)
What is protocol give example?
A protocol is a standard set of rules that allow electronic devices to communicate with each other. Examples include wired networking (e.g., Ethernet), wireless networking (e.g., 802.11ac), and Internet communication (e.g., IP).
What is protocol and its type?
A protocol is a set of rules that governs the communications between computers on a network. In order for two computers to talk to each other, they must be speaking the same language. IP/IPX (Network Layer) TCP/SPX (Transport Layer) HTTP, FTP, Telnet, SMTP, and DNS(combined Session/Presentation/Application Layers)
What are three network models?
Three types of network models and their associated distributions: (a) random network, (b) scale-free network, and (c) hierarchical network.
What are the layer 2 protocols?
Layer 2 (Data Link Layer)
- ARCnet Attached Resource Computer NETwork.
- ARP Address Resolution Protocol.
- ATM Asynchronous Transfer Mode.
- CHAP Challenge Handshake Authentication Protocol.
- CDP Cisco Discovery Protocol.
- DCAP Data Link Switching Client Access Protocol.
- Distributed Multi-Link Trunking.
What is a Layer 3 connection?
Simply put, a layer 3 switch combines the functionality of a switch and a router. It acts as a switch to connect devices that are on the same subnet or virtual LAN at lightning speeds and has IP routing intelligence built into it to double up as a router.
What layer is SMTP?
application layer
What is a layer 2 connection?
Layer 2, also known as the Data Link Layer, is the second level in the seven-layer OSI reference model for network protocol design. Layer2 is the network layer used to transfer data between adjacent network nodes in a wide area network or between nodes on the same local area network.
What is a Layer 4 protocol?
Layer 4 provides the host-to-host or end-to-end transfer of data and communication services for applications that use the layered structure of the OSI model. The session layer, Layer 5, supports this process in the OSI model. Some common protocols used in OSI Layer 4 are: User Datagram Protocol (UDP) UDP Lite.
What is a Layer 2 switch?
A layer 2 switch is a type of network switch or device that works on the data link layer (OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded. It uses hardware based switching techniques to connect and transmit data in a local area network (LAN).
