What Is A Protocol And Why Is It Important In I O Bus Technology?

What would happen if everyone used public transport?

We would need more public transport.

Buses, planes, trains etc.

all harm the environment, just as cars do.

If everyone used public transport, more buses would pollute cities..

What are the advantage and disadvantage of public transport?

There are also many advantages of using the public transport system….The disadvantages.You go where the route takes you, rather than where you wanted to go.You have no control over the time it takes to get to your destination.You ride with strangers, so you may encounter some dangerous people.

What are the advantages of public transport?

9 Benefits of Public TransportationIt benefits communities financially: … Public transportation reduces air pollution: … Increased fuel efficiency: … Reduced traffic congestion: … Saves money: … Increases mobility: … Frees up time: … Public transportation is safer:More items…•

What does bus mean?

1a : a large motor vehicle designed to carry passengers usually along a fixed route according to a schedule took the bus to work double-decker buses waiting at the bus stop. b : automobile. 2 : a small hand truck.

Why is a bus protocol important?

The bus protocol is set of rules governing how the bus works properly. If you don’t use to proper bus protocol, you may end up offending a fellow rider.

What are the 3 types of buses?

Three types of bus are used.Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices. … Data bus – carries the data between the processor and other components. … Control bus – carries control signals from the processor to other components.

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.

What are the disadvantages of a mesh network?

However, mesh topologies also have their disadvantages:full mesh networks can be impractical to set up because of the high number of connections needed.many connections require a lot of maintenance.

What is bus protocol?

In computer architecture, a bus (a contraction of the Latin omnibus, and historically also called data highway) is a communication system that transfers data between components inside a computer, or between computers. … and software, including communication protocols.

Which topology is best?

A Star Network Topology is best suited for smaller networks and works efficiently when there is limited number of nodes. One has to ensure that the hub or the central node is always working and extra security features should be added to the hub because it s the heart of the network.

What is a good bus speed?

Bus speed usually refers to the speed of the front side bus (FSB), which connects the CPU to the northbridge. … FSB speeds can range from 66 MHz to over 800 MHz. Since the CPU reaches the memory controller though the northbridge, FSB speed can dramatically affect a computer’s performance.

What is the most important protocol?

Perhaps the most important computer protocol is OSI (Open Systems Interconnection), a set of guidelines for implementing networking communications between computers. Among the most important sets of Internet protocols are TCP/IP, HTTPS, SMTP, and DNS.

What are 2 advantages of a bus topology?

Advantages of Bus TopologyEasy to connect a computer or peripheral to a linear bus.Requires less cable length than a star topology.Entire network shuts down if there is a break in the main cable.Difficult to identify the problem if the entire network shuts down.Not meant to be used as a stand-alone solution.

What is a bus type?

Computer bus types are as follows: System Bus: A parallel bus that simultaneously transfers data in 8-, 16-, or 32-bit channels and is the primary pathway between the CPU and memory. Internal Bus: Connects a local device, like internal CPU memory.

What are advantages of bus?

The use of the bus for those trips has some advantages such as:Is less stressful. … Travelling by bus is cheaper than owning and operating a car.Reduces pollution and road congestion – the more people who travel by bus, the fewer cars on the road.You do not need to look for a place to park your card.More items…•

What are the disadvantages of a bus?

The disadvantages of a bus network are:if the main cable fails or gets damaged the whole network will fail.as more workstations are connected the performance of the network will become slower because of data collisions.every workstation on the network “sees” all of the data on the network – this is a security risk.

What are the duties of protocol?

Example of Protocol Officer DutiesResearch traditions and customs.Model polite behavior.Plan foreign and domestic visits, ceremonies and special events.Identify security risks and create safety plans.Make and send invitations.Create suitable seating arrangements.Arrange photo opportunities and press conferences.More items…

What is the purpose of communication protocols?

Communication protocols are formal descriptions of digital message formats and rules. They are required to exchange messages in or between computing systems and are required in telecommunications. Communications protocols cover authentication, error detection and correction, and signaling.
