Quick Answer: What Is Protocol And Its Type?

What is BMS protocol?

A Building Management System (BMS) is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipments such as ventilation, lighting, power systems, fire systems, and security systems.

BACnet stands for Building Automation Control and Network..

Which type of VPN is best?

Best VPN Protocols: OpenVPN vs PPTP vs L2TP vs OthersHere’s a quick breakdown of the seven biggest VPN protocols today:OpenVPN is the most often recommended, and widely used VPN protocol. … PPTP is already installed on most older Windows operating systems, making it an attractive option. … L2TP/IPSec is a solid VPN choice if you’re not exchanging sensitive data.More items…•

Why is protocol needed?

Answer: In information technology, a protocol is the special set of rules that end points in a telecommunication connection use when they communicate. Protocols specify interactions between the communicating entities. … Protocols are basically needed because it’s important for the receiver to UNDRSTAND the sender.

Which protocol is used in Web?

HyperText Transfer Protocol (HTTP)HyperText Transfer Protocol (HTTP) is the most widely used web communications protocol.

What layer is SMTP?

application layerSMTP is part of the application layer of the TCP/IP protocol. Using a process called “store and forward,” SMTP moves your email on and across networks. It works closely with something called the Mail Transfer Agent (MTA) to send your communication to the right computer and email inbox.

What is the most secure protocol?

OpenVPN protocolThe most secure protocol is the OpenVPN protocol. You can choose from two different variants, called OpenVPN TCP and OpenVPN UDP.

What is a VPN protocol?

A VPN protocol is a set of rules that are used to negotiate a connection between the VPN client and the VPN server. At the moment, these are the VPN protocols you are most likely to see being used by VPN providers: PPTP. SSTP. L2TP/IPSec.

What layer is DNS?

Application LayerIn OSI stack terms, DNS runs in parallel to HTTP in the Application Layer (layer 7). DNS is in effect an application that is invoked to help out the HTTP application, and therefore does not sit “below” HTTP in the OSI stack. DNS itself also makes use of UDP and more rarely TCP, both of which in turn use IP.

What can BMS control?

Building Management Systems A BMS monitors, supervises, controls and reports on smart building technology systems. These systems may include access control, video surveillance, fire alarms, HVAC control, programmable lighting and electric power management.

What are different types of protocol?

Types of ProtocolsTransmission 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)More items…

What are computer protocols?

A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.

Which VPN protocol is fastest?

PPTPIf you want to stream at high-speeds, PPTP is the fastest VPN protocol because of its weak encryption. L2TP and IKEv2 are also fast, while OpenVPN and SSTP are slower than other VPN protocols.

What is the importance of protocol?

Computers make use of protocols as well, to enable them to communicate. Devices need to communicate. For example, a printer needs to send messages to a computer telling it that it has run out of paper or that it is ready to print while a computer needs to send the data it wants to print to the printer.

Why is BMS important?

A Building Management System (BMS) is a crucial component to any data center facility. It allows for centralized management of critical infrastructure equipment, and ensures operations are being run securely and efficiently.

What is protocol with example?

A protocol is a standard set of rules that allow electronic devices to communicate with each other. … Protocols exist for several different applications. Examples include wired networking (e.g., Ethernet), wireless networking (e.g., 802.11ac), and Internet communication (e.g., IP).

How many protocols are there?

Generally speaking, networks have three types of protocols — communication, such as Ethernet; management, such as the Simple Mail Transfer Protocol (SMTP); and security, such as Secure Shell (SSH).

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.More items…

How many types of BMS are there?

2 typesThere are 2 types of BMS Monitoring and targeting systems – designed to monitor energy use and target areas for improvement. Continuous commissioning systems – adjust your heating, ventilation, air conditioning (HVAC) and other systems continuously to meet demand.
