Amwoga KhalwaleTelevision (the electronic delivery of moving images and sound from a source to a receiver), is currently delivered in a variety of ways: “over the air” by terrestrial radio waves (traditional broadcast TV); along coaxial cables (cable TV); reflected off of satellites held in geostationary Earth orbit (direct broadcast satellite, or DBS, TV); streamed through the Internet; and … Read more
Flames burn by combining their own carbon molecules with oxygen molecules in the air to form carbon dioxide; in this regard heat flames are classified as either luminous or non-luminous flames. The terms “luminous” and “non-luminous” refer to objects based on their ability to emit light. Luminous flames do not get enough oxygen to turn … Read more
Communication is the act of conveying meanings from one entity or group to another through the use of mutually understood signs, symbols and semiotic rules. Every communication involves at least one sender, a message and a recipient. Communication is fundamental to the existence and survival of humans as well as organizations. There are two predominant … Read more
Both Acrania and Craniata belong to the phylum Chordata. Acrania are primitive chordates that lack a cranium and belong to the phylum Chordata. Craniata are higher chordates that possess a cranium and belong to the phylum Chordata. Let’s talk in details about the two. What is Acrania? Acrania is refer to a group of primitive, jawless fish … Read more
What is Euclidean Geometry? Euclidean geometry is the study of shapes and figures based on the principles given by the ancient Greek mathematician Euclid in his work “Elements.” It is the branch of geometry that deals with flat shapes and surfaces, assuming that space is continuous and follows the rules of classical geometry. Euclidean geometry … Read more
CMOS stands for complementary metal-oxide-semiconductor, and it uses pairs of transistors to create logic gates. TTL stands for transistor-transistor logic, and it uses multiple transistors to create logic gates. Lets talk more about them. What is complementary metal-oxide-semiconductor (CMOS)? Complementary Metal-Oxide-Semiconductor (CMOS) is a type of integrated circuit technology used in constructing digital logic circuits. … Read more
Remote Authentication Dial-In User Service (RADIUS) RADIUS is a networking protocol that provides centralized authentication, authorization, and accounting (AAA) services primarily for remote access. It allows a network access server (NAS) to communicate with a central server to authenticate users and authorize their access to network resources. It’s commonly used for dial-up, VPN, and wireless … Read more
What is Total internal reflection? Total internal reflection occurs when a propagating wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface. If the refractive index is lower on the other side of the boundary and the incident angle is greater than the … Read more
What are Intrinsic Sensors? Intrinsic sensors are devices that derive their measurements directly from the property or phenomenon being measured without relying on external references. They are designed to measure physical, chemical, or biological properties inherent to the system they are monitoring. Types of Intrinsic sensors Extrinsic Sensors Extrinsic sensors are devices used to measure … Read more
Cat5 & Cat5e Cat5 cables, short for Category 5 cables, are a type of twisted pair cable commonly used in Ethernet networks. These cables consist of four twisted pairs of copper wire, enclosed in a sheath made of PVC (Polyvinyl Chloride) or other materials. The twisting of the pairs helps to reduce electromagnetic interference (EMI) … Read more
