You Are Already Living Inside a Computer

Suddenly everything is a computer. Of course there is also a TV. There are also toaster and door lock, baby monitor and juicer, doorbell and gas grill. Also a faucet. Even in the garden hose. Even if trembling rotor

Have you looked inside the computer case or did you see the inside picture? Widgets may look complicated, but the inside of the computer case is not that strange. In this course you will learn some basic terms and learn more about the internal details of the computer. This is the computer's main board. It is a thin plate that holds connection to the computer port such as CPU, memory, hard drive, optical drive connector, expansion card for controlling video and audio, USB port etc The motherboard is directly or indirectly connected to each part of the computer

Each computer contains one hard drive (if not two). There is a built-in and external hard drive. The internal hard drive is inside the system unit and the external hard drive is connected to the computer as additional storage. In case of a crash, it is important that the owner of the computer buys an external hard drive and backs up his computer. External hard drives are very useful for storing information, but someone needs to pay attention to the possibility of "hard disk theft" because someone can easily connect a random external hard drive to the computer. For this reason, many people are using a fingerprint or password to access the hard drive today. Without a hard drive, we can not save much of the information contained on the computer. The hard drive has a port connected to the motherboard. Hard drives have a wide range of capacity, depending on the preference of the owner of the computer.

The price of a computer varies greatly depending on function, storage, and function. The price of a midrange computer is usually between $ 500 and $ 800, but if you already have peripherals such as monitors, keyboards, and mice you can offset some costs. A more powerful computer will cost you more than $ 1,000 to $ 3,000. The price of a smartphone is often discounted to a multi-year subscription fee with a mobile service provider such as Verizon or AT & T. Regenerated smartphones can usually be purchased for $ 100 to $ 300 on sites such as EBay and Amazon, but the price of the new main smartphone is $ 800. Depending on the size, tablet prices are usually between $ 300 and $ 700.
