A UPS is a battery backup for your PC. When the power goes off, the UPS kicks in, and continues to supply power for a period of time to the particular system. Most UPS units also provide power conditioning, which is kind of like a power strip or a surge protector. They protect your equipment from power spikes, sags, brownouts and blackouts that can come through a wall outlet, and hit your sensitive computer components. Now, which systems should you protect? Well, that depends on the values and needs of your organization. For some organizations all the PCs need to be protected with all the data on all the workstations and servers. Everything needs to be protected, so they implement a UPS on everything.

For other organizations, the workstations aren't critical. But the data on the servers is absolutely critical. So, they'll install a UPS on just the servers because they're running a web server that customers use to purchase products, or maybe a database that users use to save information. Either way, you need to decide which systems need to be protected, and which ones don't. Online UPS 3:30-4:36 Now there are two different types of UPS that we need to be concerned with. The first type of UPS is an online UPS. This is probably the best kind, and the most expensive type of UPS you can purchase. A UPS works like this. We have our wall outlet over here. We have a plug for our 110 volt power, and then we come into the UPS. The UPS has a battery in it. The PC system is then plugged into an outlet on the UPS. Which then goes into the power supply, and supplies power for the system. In this situation, the PC doesn't draw power directly from the wall outlet. Instead, it's constantly fed by the battery in the UPS. Because this is plugged into the wall outlet, the UPS continually recharges the battery, which is continually being drawn down by the PC system. An online UPS provides the best protection. And is also the most expensive. One of the problems with this, aside from cost, is the fact that this battery is continually drained and recharged. Because of this, the battery tends to go bad relatively fast. You're going to have to replace the UPS, or the battery inside the UPS frequently. But, they do provide the best protection. Offline UPS 4:37-6:45 The second type of UPS is called an offline UPS. It looks the same as an online UPS, but it functions differently. For example, we have our wall outlet over here, and our cord is plugged into our UPS system. The UPS has a battery, just like the online UPS, and our PC system is plugged in to the UPS. The difference, however, is that with an offline UPS there's a bridge. The UPS uses the 110 volt current coming in to charge the battery. However, it also bridges the current from the outlet over here to the system. That means instead of running on battery all the time, like you do with an online UPS, this system runs on 110 volts from the wall all the time. The battery is charged up, and then it just sits there. And is continually topped off. For the most part, the battery doesn't need to be charged all the time. Because the PC system isn't using it. It's using 110 volt wall current.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
