What's USB-C? An Explainer
We are all quite familiar with the USB Type A and Type B connectors. After years of USB Type A and B, USB Type-C is the latest advancement in USB ports. What is Type-C? A USB type-C is the new connector that enables data and energy transfer. USB Type C and USB 3.1 are two different properties and must not be confused as interchangeable.

With many new Mac and Windows laptops featuring the interface, it isclearthe USB-Cconnector is here to stay. Here's why that is a good thing.
What'sUSB-C?
USB-Cistheemerging industry-standard connector for transmitting both data and power. TheUSB-CconnectorwasdesignedbytheUSBImplementersForum,thegroupofcompanieswhich hasdeveloped,certified,andshepherdedtheUSBstandard.Itcountsmorethan700companiesinitsmembership,includingApple,Dell,HP,Intel,Microsoft,andSamsung.Thisisimportant,becauseit ispartof whyUSB-PCmanufacturershaveso readilyacceptedC. Contrast this with the earlier Apple-promoted (and developed) LightningandMagSafeconnectors,whichhadlimitedacceptancebeyondAppleproducts,and,due toUSB-C, are soon to be completely obsolete.
IsItLikeMicro?
TheUSB-CconnectorlookssimilartoamicroUSBconnectoratfirstglance,thoughit is more oval-shaped and slightly thicker to accommodate its best feature: LikeLightning and MagSafe,theUSB-Cconnectorhasnoupordownorientation.Lineuptheconnectorproperly,andalso youdon'thavetoflipittoplugitin.Thecablesalsohavethesameconnectoronbothends,soyoudon't have to figure out which end goes where, which has not been the case with all the USB cables we'vebeenusingforthepast20years.
USB-USB and C3.1
The default protocol together withthenewUSB-CconnectorisUSB3.1,which,at10Gbps,istheoreticallytwiceasfastasUSB3.0.But aside from on desk tops,it'smuchmorecommontoseeUSB3.1portswithUSB-Cconnectors.
USB 3.1 Gen 2 refers to data signaling rates at 10Gbps, double that of USB 3.0, and matching the speeds of single-channel Thunderbolt.

AdaptersandCables
USB-C is electrically compatible with older USB 3.0 ports, and, as we discussed above, is completely compatible with USB 3.1 ports.Buton account of the new style of port,cables or adapterswith both of therequired plugsare indeedrequiredifyou want to connect any thing that doesn'thave the USB-Cplug.Sometimes anewlaptopwillcomewiththese,inothercasesyoumayhavetopurchasethem separately. Apple,forexample,sellsa variety ofUSB cables and adapters for connecting to other technologiesincludingLightning ($25fora1-metercable) or Ethernet ($34.95foranadapter). You can also find a variety of these for PC as well in caseyoubrowseonlineretailers.Someevensupportolderormoreesotericprotocols,toensureadeviceyou havefromyearsagowillworkontoday'shardware: ItwaseasytofindUSB-Câ??toâ??DVIadapters,for instance,butwealsocameacrossonethatsplittotwoRS-232serialconnections.

DockingProcedures
Have onlyoneUSB-Cport? Do notfret,astherearemultipleUSB-C docking solutions available, both from PC manufacturers like HP and Dell,andthird-partyaccessorymakerslikeBelkin,Caldigit,andOWC. These docks can recharge your laptop, give you access to extra ports including Ethernet, HDMI, USB 3.0, and VGA, and add support for multiple monitors.
DoYouNeedUSB-C?
