All essentials that make up a computer can be categorized as hardware or software. The tangible parts of the computer are called hardware and each component of a computer has a specific and unique purpose.
The main processing components of the computer are found in the Central Processing Unit (CPU) and include the motherboard, RAM, ROM, BIOS, internal buses and external buses. The processes run by these components are saved in computer storage devices like HDDs, CDs, DVDs, floppy disks, USB flash drives etc. The configuration of these components decides the speed of the computer.
While powerful RAMs, ROMs and motherboards accommodate multiple processes in less time, additional graphics and sound cards ensure that the video and audio quality are superior. RAM for example is used to run select applications as it is processes faster than any other disk. However, the data stored on RAM is volatile and will disappear if the computer is shut down accidently or intentionally. Hard disk drives (HDD) on the other hand, store data at all times.
Computer hardware can also be categorized based on function and are divided into input and output devices. Input devices include keyboard, mouse, joysticks, touch screens, scanners, web cams, and microphones while output devices consist of printers, monitors and OLED displays.
With the wide variety of components available for PCs, laptops and other peripherals, it is important to seek help from hardware companies. Aside from offering the best components in computers, they also offer separate parts like RAMs, printer ink, toner cartridges and servicing. These companies also offer customized computers to suit your needs and budget. |
