Electronics

Electronics is the science of how to control electric energy, energy in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive electrical components and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit. The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible, and electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working system.


Electronics is distinct from electrical and electro-mechanical science and technology, which deal with the generation, distribution, switching, storage, and conversion of electrical energy to and from other energy forms using wires, motors, generators, batteries, switches, relays, transformers, resistors, and other passive components. This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers, and vacuum tubes. Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid-state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This article focuses on engineering aspects of electronics.

Automatic Water Pump Controller Using 555 Timer IC

A simple but very reliable and effective water level controller circuit diagram is shown here. The circuit uses 6 transistors, 1 NE555 timer IC, a relay and few passive components. The circuit is completely automatic which starts the pump motor when the water level in the over head tank goes below a preset level and switches OFF the pump when the water level in the over head tank goes above the full level. Automatic Water Pump Controller Circuit Using 555 Timer IC Description: This circuit will automatically switch on the water pump or motor when the level of water reaches below from the required level and then automatically switches off the pump when the tank is filled. It can be used for various purposes and not only to control the water level but also other kinds of liquids. The main component of this circuit is a 555 timer IC. There are three probes in this circuit, they will detect the high and low levels of water. The probe which is marked as the upper-level probe will detect the...

Email Security Solution

 Email Security Solution Email remains the number one method of communication for most organizations. It is also the number one method used by cyber criminals to infiltrate your network, steal or corrupt your data and damage your reputation. Methods of attacking email are growing more targeted, more sophisticated, and more dangerous. Right now, all industries are faced with an increasing number of phishing attacks, malicious attachments, and ransomware attacks. A secure email gateway is essential to protecting your business from malicious content contained within emails by preventing them from reaching their intended recipient. By placing malicious emails into quarantine or blocking the sender, a secure email gateway significantly reduces the number of successful compromises of user credentials, email hosts, and sensitive company data.   Mail Security Metrics to Prevent Unwanted Outcomes Here are the Protocols used by enterprises to prevent & mitigate security threat...

Key Considerations for a Data Center Design

Whether small or hyper scale, a cloud service provider or a business looking to keep data on-prem, good design is important to creating and maintaining a highly efficient data center.   Investment in infrastructure is expensive, so it makes sense that any organization should always look to generate maximum output from its resources, particularly as business needs dictate an ‘always on’ approach to data accessibility. Data design strategy can have an enormous impact, which in turn can lead to cost savings, greater ability to scale and reduced environmental impact. With this in mind, below are the key considerations for all businesses looking to build, run and sustain an efficient data center:   Having a Solid Power and Cooling Strategy : A large proportion of data center outages and out-of-control costs can be directly tied to the power and cooling that a data center uses. If cooling is implemented poorly, the power required to cool a data center can match or exceed the power u...
