Nyaya zilizo chini ya bahari

Watu wanapotuma ujumbe kwenda nchi nyingine, ujumbe huo mara nyingi husafiri chini ya bahari. Nyaya ndefu zimelala chini ya bahari. Zinaunganisha miji na nchi duniani kote.

When people send a message to another country, the message often travels under the sea. Long cables lie on the bottom of the ocean. They connect cities and countries all over the world.

Nyaya hizo si kubwa sana. Nyingi ni nyembamba kama hozi ya bustani. Ndani yake, kuna nyuzi nyembamba za kioo, kila moja nyembamba kama unywele. Mwanga husogea ndani ya kioo hicho kwa kasi kubwa sana na kubeba taarifa.

The cables are not very big. Many are as thin as a garden hose. Inside, there are thin strands of glass, each one as thin as a hair. Light moves through the glass very fast and carries the information.

Nyaya hizi zinafanya kazi muhimu. Zinabeba karibu ujumbe tisini na tano kati ya mia moja unaosafiri kati ya nchi. Kuna nyaya zaidi ya mia sita baharini leo, na kwa pamoja ni ndefu mno. Zinavuka kila bahari duniani.

These cables do an important job. They carry about ninety-five out of every hundred messages that go between countries. There are more than six hundred cables in the sea today, and together they are very, very long. They cross every ocean on Earth.
