Latency is the technical word that describes how long it takes data to get from one seat to another . you could measure it with a ping . Your computer send a small mail boat of information to a server , the server sends it back again , and you time how long it takes .
Latency varies calculate on three things : how fast data can physically travel through the internet , which route it takes , and whether it has to waiting line , accord to the computer hardware manufacturerApposite Technologies .
Ping speeds of 100 milliseconds and below are typical for most broadband connections.
Measuring latency
Measured in milliseconds , latency is often expressed in term of its " pear-shaped trip time " ( RTT ) , consort toFrontier . RTT is the sentence taken for a data packet to get from one connection goal to another . An alternative and less common phrase used to express rotational latency is " time to first byte " ( abbreviated to TTFB ) . TTFB refers to the sentence passed between the first part of a datum packet leaving a spot in the internet and reaching its destination .

amphetamine through the electronic web is a important problem for satelliteinternet . Most communicating satellite are in geostationary orbit , 22,300 miles ( 35,900 kilometre ) above the Earth , according toSpace.com . To get from your computing machine to a server and back again , datum has to make that long trip four time .
Ping speeds of 100 milliseconds and below are typical for most broadband connections.
SpaceXfounder and CEOElon Muskannounced a concept calledStarlinkin January 2015 , explain that the troupe destine to plunge only about 4,000 broadband artificial satellite into low - Earth orbit to provide low – cost internet . For perspective , there are only about 2,000 operational satellites in eye socket today , and humanity has set in motion only around 9,000 craft into space in all of story .
In relative to rotational latency , Starlinkis aiming to greatly boil down the RTT of data packets , cut latent period powerful down . This should make mellow - speed activities , like cyclosis and gaming , potential almost anywhere in the world .
Reducing data speeds
The approximation of a internet of geographically remote information processing system was originally proposed in the 1960s by MIT computer research worker JCR Licklider , in his theoretical piece on real – prison term interactive computer science , Man – Computer Symbiosis .
agree toScientific American , the early form , ARPANET , was limited to just a few knob in the U.S. , but the development of mailboat shift and TCP / IP protocol ( internet communication languages ) in the seventies unlock the connection ’s electric potential for elaboration around the public .

Email was being used by the 1980s , but it was n’t until Tim Berners – Lee introduced theWorld Wide Webin the other nineties that the internet start to spread beyond research and governance institutions . Since then , improvement in information transmitting speeds have allow for someone and organizations to lay in and get at ever - increasing amount of money of data and charge with child files at debauched speeds from anywhere .
Currently , fast net admittance is only useable in property with fiber optic cables , with fiber oculus internet being 20 time faster than cable internet , according to software program and computer manufacturerHP . In distant locations , communications planet provide links to the net , but the connections are notoriously dull .
Testing latency
Anybody can transmit out a ping test on their computer to test latency . All calculator that are connected to a web will have a latency examination cock built in . Web infrastructure companyCloudfarealso run this trial run on their web site . This can be used to carry out a quick datum stop number check-out procedure , without call for to instal extra software .
The process involves sending a default of 32 byte of datum to a set address and value the time take for data point to be returned to the computer , harmonize to web hosting companyIonos . The time is shown in msec .
The RTT is calculated for each examination carried out and the user is provided with a sum-up of the event . As well as data speed , any lose datum packets will be reported in this sum-up . At the end of the psychometric test , an average time taken between the information being sent and received again is calculated .
