Absorption vs. Adsorption: What is the Difference? The Basics of Absorption Absorption is a physical and chemical phenomenon in which or atoms, molecules, or ions enter or get trapped in a solid or liquid material. Unlike adsorption, the atoms, molecules, or ions are taken up by the volume and not by the surface. There are […]

Activated Carbon: Properties and Applications
An activated carbon or activated charcoal is a collective name for processed carbons with extremely porous structure and extensive surface area that allow them to effectively capture and hold materials, thus making them suitable for adsorption and chemical reaction. The processing of carbon into an activated carbon generally involves the treatment of char with heat […]
Purpose of Bird Vocalization
Research in ornithology has explored and explained the different functions of bird vocalization. Ornithologists specifically determine these functions by analyzing the acoustic structures of bird calls and bird songs, how specific species of birds produce them, how they are perceived by conspecifics, and the context in which they are produced. Difference Between Bird Calls and […]
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 […]
LED Lamps vs. Fluorescent Lamps: Which One Is Better?
Fluorescent lamps started replacing incandescent lamps in the 1950s following the commercialization of the underlying fluorescence technology. These lamps soon dominated the market in the 1980s and the 1990s. On the other hand, light-emitting diode or LED lamps were under development as early as the 1960s, but these fixtures only produced light in the low […]
Advantages and Disadvantages of PNG Format
Portable Network Graphics or PNG is a file format for compressing digital images developed initially as an improved and non-patented replacement for Graphics Interchange Format or GIF. However, this format has now been used as a better replacement for the JPEG standard. The Advantages of the PNG Format 1. Lossless Compression: One primary advantage of […]
Advantages and Disadvantages of JPEG Standard
JPEG is a compression standard for digital images. Note that JPEG is an initialism for Joint Photographic Expert Group, an organization that created and maintains the JPEG, as well as the JPEG 2000, and JPEG XR standards. The standard has several file formats to include the JPEG Exchange Image File Format and JPEG File Interchange […]
The Three Factors of User Authentication
Websites and apps are increasingly utilizing layered authentication to promote security and privacy online. As a backgrounder, layered authentication is an identity and access management process that uses two or more layers based on the so-called factors of authentication. A user needs to present two or more factors to grand him or her access to […]
Hard Disk Drive vs. Solid-State Drive
Hard disk drive or HDD and solid-state drive or SSD are two major types of data storage device. Take note that phonographic recording and optical discs, as well as DNA-based storage, are other types of storage mediums and technology. However, HDDs and SSDs are more popular because of their reasonable manufacturing cost and better storage […]
