  1. 6. An electrical appliance that provides the necessary power to operate a computer. Computers are powered by electricity, and the __ converts the alternating current (AC) from the electric outlet into direct current (DC). The __ in a computer can be an internal or external component.
  2. 9. A hardware input device that is used to move the cursor or pointer on computer screens. It can also be used to run computer programs, select items in a graphical user interface, and manipulate objects in the computer world. Some common examples of how it can be used are clicking on buttons, scrolling up and down the screen, selecting files, opening folders, and so on.
  3. 10. The backbone of our computer system. It's the central processing unit or CPU. It connects all the other components, like memory and graphics card, to the power supply. The __ is where all the wires are plugged in and it's also where you place your RAM, which is your computer's working memory.
  4. 12. A computer's __ is a type of computer memory that stores information so the CPU can access it directly. This means that opening many programs, running various processes or accessing multiple files simultaneously is likely to use a lot of __. The more __ you have, the more data your system can process at one time.
  5. 15. These are used to connect your computer to other devices like printers and speakers, among many others. However, not all __ are the same. You'll find different types of an __ on laptops and desktops that allow you to use them in different ways.

  1. 1. They are circuits found in video cards, which control the video output of the computer. The __ is responsible for formatting the data that is sent to the monitor or TV. __ can be implemented by either an onboard circuit on the motherboard or a separate card that connects to the motherboard through a slot.
  2. 2. A piece of hardware inside a computer that stores information. It's used to store software and data in a safe place, which can be accessed when needed. With magnetic storage, there are no moving parts - unlike a CD or DVD player in which you need to move a disk in order to access data. You can think of it as "a closet" where all your stuff is stored safely.
  3. 3. Personal computers use a __ to display data, run the software, and interact with the user. An electronic visual display that connects to your computer or laptop. It is used for displaying images, text, videos, games, web pages, and more.
  4. 4. A computer chip that processes and amplifies sounds. It produces a signal to the speakers, headphones, or other output devices. It is also called an "audio card" Computers with __ are capable of playing digital music files and videos, as well as speech synthesis. Nowadays, most computers have these built-in.
  5. 5. It is in the computer. It is a very important component for your PC. If your __ is not working correctly, your computer will be overheating and it may cause damage to other components. The __ helps cool the CPU and other internal parts of the computer. It also provides negative pressure and removes dust and debris from the inside.
  6. 7. The set of devices that are used to access data. There are three major parts of the __: input, output, and storage. Input devices, also called input peripherals, are typically what data is first inputted into the computer. Output devices are where data is displayed. Storage devices store data so it does not need to be present in memory or processed by a CPU.
  7. 8. An input device used to enter characters and functions into the computer system by pressing buttons, or keys. It is the primary device used to enter text. It typically contains keys for individual letters, numbers and special characters, as well as keys for specific functions.
  8. 11. A type of memory chip that can be read from but not written to. In other words, it's a form of data storage that can't be changed after being programmed. Often used to store a computer's basic start-up instructions and certain types of data, such as your car's onboard computer system and a calculator's data tables.
  9. 13. This is used in PCs to read and write CDs and DVDs. Reads the data from the disc, which can then be transformed into a digital file that is readable by the computer. This makes it easy to backup files, play music or movies, or copy data from one disc to another. They are often used for installing software on your computer, moving data between computers, or writing new programs.
  10. 14. The brain of a computer. The __ processes information and runs programs. It functions as a control unit that executes programs according to instructions in its program memory.
