$\huge{\fcolorbox{red}{blue}{Uses\:of :-}}$

Ram :-

RAM allows your computer to perform many of its everyday tasks, such as loading applications, browsing the internet, editing a spreadsheet, or experiencing the latest game. Memory also allows you to switch quickly among these tasks, remembering where you are in one task when you switch to another task.

Printer:-

A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.

Plotter:-

Plotters draw lines on paper using a pen. In the past, plotters were used in applications such as computer-aided design, as they were able to produce line drawings much faster and of a higher quality than contemporary conventional printers, and small desktop plotters were often used for business graphics.

USB port :-

Mostly, USB cables are connected to computer units directly to peripheral devices like mobile phones, cameras, camcorders and printers/scanners. The main objective of these cables is to effectively, quickly and properly gather or transfer data from one device to another.

QR code scanner:-

This scanner allows you to automatically transfer information about the product to your computer system so that you can keep track of income, place orders for new inventory and take note of sales trends. Some scanners are USB-compatible so that you can plug them into a standard computer with a USB port.
