hello everyone in this Article we're going to talk about a technology called powerline networking now sometimes there might be cases in your home or office where you wanted a certain computer in a certain part of the building to be able to access the Internet but for whatever reason network cabling or Wi-Fi just wasn't an option in that part of the building maybe because of difficulties in the structure of the building or interference or whatever so to help solve this kind of problem a newer technology gave the ability to network using the existing electrical system of the building powerline networking gives the ability of Ethernet networking over power so for example let's say you needed this computer up here to be able to access the Internet but for some reason you can't get any network cables or any Wi-Fi signal to reach that computer so in this case we're going to use powerline networking so we're going to need a couple of powerline adapters like these here and these powerline adapters plug directly into a power outlet and they have a built-in Ethernet port for an rj45 connector so one adapter plugs into the power outlet next to the modem or router down here and then you would plug in Ethernet cable from the modem or router into the powerline adapter then you will plug the other powerline adapter into the power outlet next to this computer up here and then you will connect an ethernet cable from the network port of the computer into the powerline adapters Ethernet port so now Ethernet network data will use the building's existing electrical wiring to deliver networking data to the other powerline adapter so that the computer can access the Internet now powerline networking works similar to DSL technology because in DSL the same phone line is able to carry both data and voice but they are on different frequencies which is very similar to how powerline networking works where the same lines are used to carry electricity and network data at different frequencies so this is an extremely convenient option to have especially when running new cables is too much of a hassle or if there's too much interference to use Wi-Fi you can just simply use the building's existing electrical wiring to network data and that's pretty much it there is no software configuration or real hardware configuration you just plug in the adapters and plug in the network cables and you're ready to go and if you're interested in getting some of these powerline adapters I have a link in the description below of the network adapters that I recommend
what is the BIOS CMOS and UEFI so that's what we're going to talk about in this video now BIOS stands for basic input/output system the BIOS is firmware that's built into the motherboard that initializes the computer's hardware as the computer is being booted and then after it initializes the hardware it then searches for a boot device such as an optical drive or a storage drive to boot software such as an operating system so from the start when you first turn on the computer the computer does what's called a power-on self-test or post which is run by the bios it tests the computer to make sure all the requirements are met and if the hardware is working correctly before starting the operating system if the computer passes the test the internal speaker will make a short single beep which indicates that the computer has passed the test and is booting up normally however if there are no beeps or multiple beeps then that means that the computer has failed the test and s...
