Answer:
1. The CPU is what allows the computer to function. It uses instructions in the software that is installed on the computer, or that the computer is accessing via the cloud, to execute tasks. Processor speed impacts how quickly tasks can be performed. This computer part is sometimes referred to as the device’s brain.
2. A computer’s hard drive represents its long-term storage capacity. Modern computers may have an internal hard drive, which is a mechanical drive that spins. Some of the latest model machines have a solid state drive (SSD) instead. An SSD is a newer type of long-term storage device that allows for faster retrieval of data. Some machines have both a traditional hard drive and an SSD.
3. RAM is the acronym for random access memory, which represents a computer’s short-term memory. When a computer is actively performing a task, the device is using RAM to do so. If you enjoy watching movies or videos on your computer or you tend to keep a lot of applications open at the same time, then you will want a computer that has a lot of RAM. The less RAM a computer has, the fewer tasks it can perform at one time and the slower each task will be.
4. Computers have ports, which are slots that can be used to connect the computer to other devices. A computer’s high-definition media input (HDMI) port is used to connect the device to video outputs, such as an external monitor, projector or television screen. An HDMI cable, with ends that match the shape and size of the port, must be used to connect the computer to these devices.
5. Computers also have universal serial bus (USB) ports, which are used to connect other types of devices to computers. They are often used to connect printers, scanners, headphones, cell phones, and external storage devices. A USB cable is used to connect devices to a computer via a USB port.
6. A keyboard is an input device. It allows a computer user to issue commands to the computer by entering letters, numbers, special characters, or functions. Laptop computers have a built-in keyboard while desktop models typically have one that attaches via a USB cable or that connects wirelessly to the computer.
7. A computer’s screen is the area where information is displayed to the end user. It is the face of the computer’s monitor. The screen is built into a laptop but is a separate device for desktop systems. If you are using a word processing program, the information you type will appear on the screen. If you are using a computer to play a game or watch a movie, that's what shows on the screen.
8. MOUSE. A pointing device that we use to move the cursor on the screen, the mouse buttons are used to interact with various on-screen elements. A standard mouse these days will usually come with at least 3 buttons (left, center, right) and a scroll wheel. Although there are some mouse designs with a lot more buttons, and more meant for the purpose of gaming.
9. power supply. This is the component that converts power from the wall outlet to one that the computer needs.
10. web cam. Web cameras are used to take photos and videos. Most modern laptops, tablets, and smartphones come with a built-in camera.
