Lesson 3: Basic Parts of a Computer /en/computerbasics/what-is-a-computer/content/ Introduction The basic parts of a desktop computer are the computer case, monitor, keyboard, mouse, and power cord. Each part plays an important role whenever you use a computer. Watch the video below to learn about the basic parts of a computer. The computer case is the metal and plastic box that contains the main components of the computer, including the motherboard, central processing unit (CPU), and power supply. The front of the case usually has an On/Off button and one or more optical drives. Computer cases come in different shapes and sizes. A desktop case lies flat on a desk, and the monitor usually sits on top of it. A tower case is tall and sits next to the monitor or on the floor. All-in-one computers come with the internal components built into the monitor, which eliminates the need for a separate case. Monitor The monitor works with a video card, located inside the computer case, to display images and text on the screen. Most monitors have control buttons that allow you to change your monitor's display settings, and some monitors also have built-in speakers. Newer monitors usually have LCD (liquid crystal display) or LED (light-emitting diode) displays. These can be made very thin, and they are often called flat-panel displays. Older monitors use CRT (cathode ray tube) displays. CRT monitors are much larger and heavier, and they take up more desk space. Keyboard The keyboard is ...

a device, usually electronic, that processes data according to a set of instructions. The digital computer stores data in discrete units and performs arithmetical and logical operations at very high speed. The analog computer has no memory and is slower than the digital computer but has a continuous rather than a discrete input. The hybrid computer combines some of the advantages of digital and analog computers: See also • A programmable machine that performs high-speed processing of numbers, as well as of text, graphics, symbols, and sound. All computers contain a central processing unit that interprets and executes instructions; input devices, such as a keyboard and a mouse, through which data and commands enter the computer; memory that enables the computer to store programs and data; and output devices, such as printers and display screens, that show the results after the computer has processed data.

Computer artificial intelligence's impact on society is widely debated. Many argue that AI improves the quality of everyday life by doing routine and even complicated tasks better than humans can, making life simpler, safer, and more efficient. Others argue AI poses dangerous privacy risks, exacerbates racism by standardizing people, and costs workers their jobs leading to greater unemployment.

If you're reading this right now, you're using a computer. Maybe it's a laptop, maybe a desktop computer, or perhaps even a smartphone. They may look different, but they all share the same underlying technology. The more we understand how that technology works, the more we can use the computers around us to help make our world better. Binary code works with base-2, which means that a binary digit, when on, will give you a value of 2^n, where n is the place you are in. For example, if you are working with a 4 bit chunk, 0000, the places represent 2^3, 2^2, 2^1, and 2^0 from right to left. Having a 1 in a place means that you add its value to the total. For example, 1011 is 8+2+1 or 11. Computers use these added up values to represent different things, such as in ASCII, where different numbers represent different characters. If you are wondering why we use 1s and 0s, it has to do with logic gates being only currently able of having an on or off position, with 1 being on and 0 being off.
