What are the Different Types Of Computer Hardware?

Computers have become the backbone of countless operations and activities across the globe, serving to enhance how we work, communicate, shop, learn, and so much more. Whether a computer is designed for personal use or for work, many of the same hardware components are used to enable such devices to function as intended. In this blog, we will discuss the most common hardware types that are associated with computers, allowing you to better understand how such advanced systems are made up and how they function.

Central Processing Unit (CPU)

The CPU can be considered the brain of a computer, capable of receiving and executing program instructions. As such, they are tasked with handling the basic arithmetic, I/O operations, logic, and management that is necessary for standard computer operations. Generally, such devices are implemented on integrated circuit (IC) microprocessors, containing all the necessary elements and semiconductors for functionality.

Random Access Memory (RAM)

RAM is one of the primary hardware parts of computers, capable of reading and changing data and machine code in any order. Modern RAM components consist of IC chips paired with MOS memory cells, and multiplexing and demultiplexing circuitry enables data lines and accessed storage to be linked for reading and writing. As a form of volatile memory, RAM will not retain data when power is removed from the system.

Secondary Storage Devices

Secondary storage devices consist of all systems that retain data until it is deleted or overwritten. Non-volatile in design, the most common options for secondary storage devices are hard disk drives (HDD) and solid-state drives (SSD). HDDs are either internal or external for installation, and a magnetic head is used to write and read data on spinning platters. SSDs, on the other hand, forgo moving parts as data is stored electronically through flash-based technology. While exhibiting faster reading and writing speeds over HDDs, SSDs are often more expensive and exhibit shorter service lives even under optimal conditions.


While various parts such as the CPU, memory, and secondary storage allow for basic computer operations to be carried out, there are certain hardware parts and accessories necessary  for the control and manipulation of data to be possible. With keyboards and mice, individuals can type, click, and otherwise direct the computer as needed for the means of carrying out various tasks. If sound is desired or required, then one may take advantage of speaker systems, headphones, or other similar equipment.


For visual representation of computer processes, computer monitors or television screens may be relied on. While CRTs once dominated the market, LCD, LED, and OLED options have taken over as more advanced display systems have come about. Depending on one’s particular needs, screen sizes can range anywhere from 12 inches to 40+ inches.


For both business and personal use, printers and printer parts can be extremely beneficial. With such devices, one can print out various data and information onto a hard paper copy that can be safely stored and used as necessary. As of the present, the most common types of printers that are in use include dot-matrix, laser, thermal, inkjet, plotter, and chain & line printers. Each printer will typically differ in how it executes a printing job, utilizing varying components and technologies.
