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
What is Layer 2 Switch? Layer 2 switches, also known as Ethernet switches or LAN switches, are network devices that operate at the Data Link Layer (Layer 2) of the OSI (Open Systems Interconnection) model. These switches are designed to connect multiple devices within a local area network (LAN) and facilitate the efficient forwarding of … Read more
The name chordate is derived from the word notochord. A notochord is a flexible, rod-shaped structure that is found in the embryonic stage of all chordates and in adulthood of some adult chordate species. The notochord is located between the digestive tube and the nerve chord, it act as the primary axial support of the … Read more
Throw The Java throw keyword is used to explicitly throw an exception. In Java, exceptions can be categorized into two types: Unchecked Exceptions: They are not checked at compile-time but at run-time. Checked Exceptions: they are checked at compile-time. Usually, we don’t need to handle unchecked exceptions. It’s because unchecked exceptions occur due to programming … Read more
Voltage Amplifier A voltage amplifier is an amplifier that amplifies given voltage for a larger voltage output. It is characterized by a high input impedance and low output impedance. This is useful for reading and adapting small signals such as boosting an audio signal before sending it on its way to speakers. The voltage amplifier … Read more
What Is An Entity? An entity set is a collection or a set of all the entities that share the same attributes set but with a different set of values for some attributes. The entity can be classified into two basic categories: Weak Entity Strong Entity What Is a Strong Entity? A strong entity is … Read more
Gravity Control In gravity controlled instruments, a small weight is attached to the moving system in such a way that it produces a controlling torque, when the moving system is deflected position. The controlling torque can be varied quite easily by adjusting the position of controlling weight upon the arm. Another weight is attached for … Read more
What Is a Colorimeter? A colorimeter is a light-sensitive instrument used for measuring the transmittance and absorbance of light passing through a liquid sample. The instrument measures the intensity or concentration of the color that develops upon introducing a specific reagent into a solution. There are two types of colorimeters, color densitometers and color photometers. … Read more
What Is Combustion/Burning? Combustion is the scientific word for burning. In a combustion reaction, a substance reacts with oxygen from the air and transfers energy to the surrounding. Combustion releases a large amount of energy in a single step and most of it changes into heat and some at times into light, raising the temperature … Read more
What Is Imbibition? Imbibition is the process of adsorption of water by substances without forming a solution. The swelling of soaked seeds, the swelling of a wooden door during rains, germination of seeds, and absorption of water by roots are some of the examples of imbibition. Imbibition is the initial step in seed germination, If … Read more
