HDD/SSD : HARDRIVES.


In a personal computer, a hard disk drive (HDD) is the mechanism that controls the positioning, reading, and writing of the hard disk, which furnishes the largest amount of data storage for the PC. Although the hard disk drive (often shortened to "hard drive") and the hard disk are not the same thing, they are packaged as a unit and so either term is sometimes used to refer to the whole unit.



ODD ; OPTICAL DRIVES.



In computing, an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs.



MONITORS.



A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) or a flat panel LED display, while older monitors used a cathode ray tubes (CRT).




CPU : CENTRAL PROCESSING UNIT.



The CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the "brains" of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program.



RAM: RANDOM ACCESS MEMORY.



RAM (Random Access Memory) is storage used for a place to hold data. Think of it as a big filing cabinet that keeps things ready for the CPU in your phone to present it to your eyes and ears. It's infinitely (almost) re-writable, very fast, and used differently by different operating systems
