What Is Symmetric Encryption? Symmetric encryption is a type of encryption whereby only one cryptographic key (secrete key) is used to both encrypt and decrypt electronic information. The entities communicating through symmetric encryption must exchange the key so that it can be used in the decryption process. When a server and client are in need … Read more
The cell is the basic unit of life. All organisms are made up of cells (or in some cases, a single cell). Most cells are very small; most are invisible without the use of a microscope. Cells are covered by a cell membrane and come in many different shapes. The cell can be oval, rod-shaped, … Read more
What Is Flora ? Flora can be defined as a group of indigenous plants (trees, plants and other forms of life such as fungi and algae) in an ecosystem of a given geographical region of the planet or have grown in an area during a certain time period. Examples of flora include: Grassland Giant redwood … Read more
Haemoglobin Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules (globulin chains) that are connected together. The normal adult hemoglobin (abbreviated Hgb or Hb) molecule contains two alpha-globulin chains and … Read more

The basis of comparison include: Description, official launch, configuration, encryption, protocol, licensed and unlicensed spectrum, data transmission rates, channel bandwidth, Coverage, IEEE Standards, bandwidth efficiency and version Standards. Key Difference Description Wi-Fi is an acronym for Wireless Fidelity. It is a wireless networking technology that … Read more
What is a Relay? Relays are switches that open and close circuits electromechanically or electronically. Relays are the primary protection as well as switching devices in most of the control processes or equipments. All relays respond to one or more electrical quantities like voltage or current such that they open or close contacts or circuits. … Read more
What Is Kerberos Protocol? Kerberos is a computer-network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Kerberos builds on symmetric key cryptography and requires a trusted third party and optionally may use public-key cryptography during … Read more
What Is A Waterfall Model? The waterfall Model is a software development process developed by Dr. Winston Royce in 1970. In waterfall approach, the whole process of software development is divided into separate phases. The outcome of one phase acts as the input for the next phase sequentially. This means that any phase in the … Read more
Although it is somehow impossible to tell the physical differences between male and female mosquitoes with the naked eye, it is simple enough to tell the differences when the mosquito is viewed under a microscope or magnifying glass. In this article, learn the difference between male and female mosquito. The basis of comparison include: Antennae, … Read more
What Is Spiral Model? Spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models such as incremental, waterfall or evolutionary prototyping. Each phase in spiral model begins with a design goal … Read more
