A dot matrix printer is a printer device based on impact printing. It uses a print head that moves back and forth and prints by impact or by striking an ink-soaked cloth ribbon against the surface of the paper. Compared to inkjet printers or laser printers, dot matrix printers are more popular in specific settings […]

Laser Printer: Advantages and Disadvantages
A laser printer is one of the most common types of consumer electronic device used for recreating digital images to a variety of media, particularly papers, substrates, and other compatible surfaces. It is specifically a non-impact printer that works by firing a laser beam on a negatively charged, mechanical, and photosensitive cylinder called a drum. […]
Inkjet Printer: Advantages and Disadvantages
An inkjet printer recreates digital images by accurately pushing or depositing droplets of inks onto a paper or substrates and other printable surfaces. As one of the most common types of printers in the market, its availability ranges from inexpensive consumer units to more expensive commercial models. Four major companies manufacture and market inkjet printers […]
AMOLED Display vs. PMOLED Display
AMOLED display and PMOLED display are two subtypes of OLED display technology based on an underlying principle of addressing pixels. The former stands for active matrix organic light-emitting diode or active matrix OLED while the latter corresponds to passive matrix OLED. What is the Difference Between AMOLED display and PMOLED display? What are Active Matrix […]
Difference Between OLED and AMOLED
An organic light-emitting diode or OLED display is a type of display technology based on electroluminescent organic compounds. These organic compounds essentially emit a particular frequency or color of light with the application of an electric current. On the other hand, an AMOLED stands for active matrix organic light-emitting diode. Hence, an AMOLED display is […]
Hard Disk Drive: Advantages and Disadvantages
Pros: The Advantages of HDD 1. One of the notable advantages of a hard disk drive or HDD is that it is cheaper when compared to a solid-state drive or SSD. An SSD with a similar storage capacity can be twice more expensive than an HDD. What this means is that computers with an HDD are […]
Solid-State Drive: Advantages and Disadvantages
Pros: The Advantages of SDD 1. Compared to a hard disk drive or HDD, one of the advantages of a solid-state drive or SSD is that it has a faster read-write speed because of the absence of moving parts. It is specifically 25 times to 100 times faster than HDD, which in turn, means wider bandwidth, […]
OLED vs. IPS LCD: Which One is Better?
Two display technologies currently dominate the consumer electronics market. These are organic light-emitting diode or OLED displays and in-plane switching liquid crystal display or IPS LCD. As a backgrounder, an OLED uses organic compounds that emit light in response to an electric current. On the other hand, an IPS is a specific type of LCD […]
TN LCD: The Pros and Cons
The Pros of TN LCD 1. One advantage of twisted nematic or TN LCD over other display technologies such as IPS LCD, VA display, and OLED is affordability. The technology behind TN LCDs is easier to implement, thus translating to inexpensive manufacturing cost and affordable market price. 2. Energy efficiency is another strength of twisted nematic LCD […]
IPS LCD: The Pros and Cons
The Pros of IPS LCD Technology 1. One of the key advantages of in-plane switching or IPS LCD technology is that it produces more accurate and thus, better images than twisted nematic or TN LCD. To be specific, it has a color depth capable of producing 16.7 million possible colors. 2. Wide viewing angle is another […]
