Hubs and switches serve as a central connection for all of your network equipment and handles a data type known as frames. Frames carry your data. When a frame is received, it is amplified and then transmitted on to the port of the destination PC.
The Milky Way is estimated to contain 100â400 billion stars. There are likely at least 100 billion planets in the Milky Way. The Solar System is located within the disk, about 27,000 light-years from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm.
The Milky Way appears about equally bright in a band around the sky. The Milky Way is a spiral galaxy which formed about 14 billion years ago, and looks like a large pinwheel rotating in space. Dust, gas and stars fan out from the center of the Milky Way in long spiraling arms. Our galaxy is made of clouds of dust and gas called nebula, stars, comets, meteors, asteroids, and planets. Our own Sun and Solar System also are a part of the Milky Way Galaxy; our Solar System is about 26,000 light-years from the center of the Galaxy. The Sun travels around the center of the Milky Way, taking about 250 million years to complete an orbit. All objects in the Milky Way rotate around the Galaxy's center.
