Advantages and Disadvantages of 3 Point Starter

A 3-point starter is a device whose main function is starting and maintaining the speed of the DC motor. The 3-point starter connects the resistance in series with the circuit reduces the high starting current and protects the machines from damage. Here this post gives the advantages and disadvantages of 3 point starter to better understand this topic.

Advantages of 3-Point Starter 

  • A 3-point starter is used with DC shunt motors.
  • Three-point statrter helps to speed control of the motor.
  • This starter can be also used in lathe factories and spinning mills.
  • It reduces the high starting current.
  • A three-point starter protects the motor from short circuits and overload issues.

Disadvantages of 3 point starter

  • The main drawback of 3 point starter motor is, that it is a huge variation of speed by adjustment of the field rheostat.
  • This starter is not suitable for variable-speed motors.
  • When increasing the high resistance to achieve a high speed, the field current will always be extremely low.
  • Large field current adjustments are not suitable with  3-point starters.
  • The holding electromagnet won't be able to endure the force of the spring if the field current is relatively low.
  • The NVC fails to hold the handle in the ON position, which would disconnect the motor from the supply, at a low field current.
  • This magnet can disconnect the H handle from the power source and release its arm via the usual motor function.
  • When there is no volt trip coil associated in the parallel field, the 4-point stater can therefore be used.
  • The field winding does not have extra resistance in series, so speed regulation isn't possible.
  • The condition circuit may be damaged during a fault because there isn't any extra protective resistance.

Difference Between Longitudinal and Transverse Wave

Longitudinal waves have the medium's particles moving back and forth in the same direction as the wave. Transverse waves travel in one direction with the wave and the medium particles moving at an angle to it. We have covered in this article the difference between Longitudinal waves and transverse waves to better understand this topic.

What is a Longitudinal wave?

A longitudinal wave is one in which the medium particle displacement is parallel to the wave's direction of propagation. A compression wave is the most basic kind of longitudinal wave, where the medium particles are moved so that they are closer together than they would be if the wave hadn't happened.

What is Transverse Wave?

A wave with oscillation perpendicular to the direction of energy transfer is called a transverse wave. As stated in various ways, the particles of the medium vibrate perpendicular to the direction the wave is traveling. Another name for this kind of wave is shear wave.

Difference between Longitudinal wave and Transverse Wave

  • In the Longitudinal wave, the movement of the particle is along the direction of the wave, on the other hand, transverse wave the movement of the particle is perpendicular to the direction of the wave.
  • Longitudinal waves can travel through all states of matter, on the other hand, Longitudinal waves travel only in solids.
  • Compression and rarefaction are the two components of longitudinal waves. Crests and troughs create a transverse wave.
  • Sound waves are Longitudinal waves, and Light waves are transverse waves.
  • In Longitudinal waves the movement of particles is usually parallel to the movement of energy, in contrast, in transverse waves, the particles are displaced perpendicular to the direction of the traveling wave.
  • The production of longitudinal waves can take place in any medium solid, gas, or liquid. The production of Transverse waves can take place in liquid and gas mediums only.

Difference Between Land Breeze and Sea Breeze: Easy Comparison Guide

The difference between a Land Breeze and a sea breeze will be covered in this article. The wind that blows during the night is known as a land breeze. The wind blows from the land to the sea when there is a land breeze. It happens in the autumn and winter months. Another name for it is an offshore breeze. The breezes in this breeze are dry and shallow. The wind that blows during the day is known as a sea breeze. So here this article gives the difference between Land Breeze and Sea Breeze to better understand this topic.

What is Land Breeze?

All the land's heating and cooling rates accelerate. As a result, the sand or soil cools before the water after sunset. There is currently low pressure above the ocean due to the land air being colder than the sea air. Air from the land flows towards the sea as a result. Land breeze, as its name implies, is wind or breeze that blows from the land towards the sea. Another name for it is an offshore breeze. Since the land air is colder than the sea air, it usually happens at night or in the early morning.

What is Sea Breeze?

When the sun is shining during the day, the air on land warms more quickly than the air at sea. The sea air is therefore heavy and colder at this time of day and moves in the direction of land. Sea breezes, as their name implies, are breezes or winds that originate in the sea and move towards land. It frequently happens in the summer. Another name for it is Onshore breeze.

Difference between Land Breeze and Sea Breeze

  • The land breeze is shallow, and The sea breeze is deep.
  • The Land breeze is normally experienced during winter and autumn. This is due to the cooler nights. Sea Breeze normally occurs during the spring and summer seasons. This is due to the consequential temperature differences between land and water.
  • Land Breeze's pace spans from 5 to 8 knots, on the other hand, Sea breeze pace spans from 10 to 20 knots.
  • Land Breeze is a weak breeze, The sea Breeze is a relatively stronger breeze than a land breeze.
  • Land breeze takes place when land air is hotter than sea air, On the contrary, Sea Breeze takes place when sea air is hotter than land air.
  • The temperature might remain the same when the land breeze occurs, on the other hand, sea breeze tends to decrease the air temperature.
  • Land breezes usually blow dry winds, But the sea breeze contains more amount of moisture due to the particles absorbed from the water bodies.
  • Land breeze leads to the development and formation of clouds, and Sea Breeze helps in overcoming fatal storms.
  • Land Breeze are dry winds, and Sea Breeze are wet winds.
  • The land breeze is the breeze in which the wind blows from the land to sea, The sea breeze is the breeze in which the wind blows from the sea to land.
  • Land Breeze is also known as the offshore breeze, and Sea Breeze is also known as the onshore breeze.
  • Land Breeze does not contain moisture, Sea Breeze winds contain moisture.
Similarities Between Land Breeze and Sea Breeze
  • Both Land and Sea Breeze occur near the sea coast.
  • Both Breezes occur due to low-pressure generation.
  • They both influence humidity, air temperature, and precipitation rates.
  • Both breezes affect temperature.

Concave and Convex Mirror Differences: A Complete Comparison Guide

In physics, there are two types of spherical mirrors, known as concave and convex mirrors. Mirrors with a reflecting surface that is a portion of a hollow glass sphere are known as spherical mirrors. They differ from planner mirrors in that they usually consist of glass. Spherical mirrors with an inward curved reflecting surface are called concave mirrors. Mirrors with an outward curving reflected surface are known as convex mirrors.

What is Concave Mirror?

Concave mirrors are curved mirrors with the reflecting surface on the inner side of the curved shape. They have an inwardly curving surface that resembles the inner surface of a hollow sphere. Concave mirrors cause light rays to cover or come together after reflection, making them converging mirrors as well. Concave mirrors can create real or virtual images depending on the object and the mirror's position.

What is a Convex Mirror?

A convex mirror is a curved mirror in which the outside of the curved shape acts as the reflecting surface. Its surface has an outward curving shape that is similar to a sphere outside. Because convex mirrors allow light beams to diverge or spread out after reflection, they are often referred to as diverging mirrors. No matter where the object is, convex mirrors always create virtual, erect, and reduced pictures.  They are frequently utilized in applications like security and rearview mirrors that demand a large field of vision.

Difference between Concave and Convex Mirror

  • A concave mirror is a spherical mirror with the surface of the reflection curved in an inward direction, While a convex mirror is a spherical mirror with a reflecting surface with an outward bulge.
  • The projection of an image on a Concave mirror can be done on the screen, while for a convex mirror, image projection cannot be done on the screen.
  • The magnification for a concave mirror can be less than equal to or greater than 1, on the other hand, the value of m of a convex mirror is smaller than 1.
  • A concave mirror is of a converging nature and thus is also known as a converging mirror whereas a convex mirror is of a diverging nature and hence is also known as a diverging mirror.
  • As the focus of the concave mirror exists on the front side its focal length is positive whereas that of the convex mirror lies on the backside hence focal length is negative.
  • Contrary to the convex mirror, which has its center of curvature on the rear, the concave mirror has its focus and center of curvature in front of it.
  • A concave mirror produces an image that is generally larger than the actual image hence the produced image is of a magnified nature. On the other hand, a convex mirror produces an image that is generally smaller than the actual image, and therefore, the image produced appears to be diminished.
  • An image can be projected on a screen as if they are real in a Concave mirror, on the contrary image cannot be projected on a screen as they are virtual in a convex mirror.

WPA3 Features

Wi-Fi Protected Access 3, or WPA3, is the most recent version of widely used wireless network security. When compared to the widely used WPA2 standard, it increases security while maintaining backward compatibility. WPA3 was released by the Wi-Fi Alliance later in 2018. Companies have been using WPA2 protocols since 2004, and the new regulation expand upon them. WPA3 offers forward secrecy, with personal mode supporting 128-bit encryption and corporate mode supporting 192-bit encryption. WPA3 employs a less dangerous first key exchange technique called simultaneous authentication of equals in place of pre-shared key exchange.

The main key features of WPA3 are it is management frame protection, Transition mode, And simultaneous authentication of Equal(SAE). So let us understand the main key features of WPA3 to better understand this topic.

WPA2 uses the AES standard rather than the RC4stream cipher, in contrast to WEP and WPA. WPA's TKIP is replaced by CCMP. In contrast, WPA3 is 128-bit encryption in WPA3 personal mode(192-bit in WPA3-enterprise) and forward secrecy. WPA3 also replaces the pre-shared key exchange with simultaneous authentication of equals, a more secure way to do an initial key exchange.

What are the main key features of WPA3?

Management Frame Protection

The unicast management frames are encrypted to stop unauthorized client authorization. As a result, WIDS/WIPS systems will depend more on alerting the system administrator about rogue or honeypot APs, for example, and will have fewer options to impose customers' policies using brute force methods.

Transition mode

The enhanced open, personal, and enterprise modes can all function in transition mode. For clients that do not support WPA3, this implies returning to WPA2.

Simultaneous authentication of equal(SAE)

Even in cases where password complexity criteria are not met, SAE offers a more secure password-based authentication and key agreement process. It guards against attacks using brute force and makes it much more difficult for someone to decrypt a session either during or after it has begun just by knowing the passphrase.

What is WPA3?

What is Wi-Fi protected Access 3?

WPA3, or Wi-Fi protected access, is the most recent Wi-Fi encryption standard. Device that support the WPA3 standard will have an added layer or protection if you activate WPA3, on your eero network. This includes MEP(management frame protection), SAE(Simultaneous Authentication of equals), and a novel encryption techniques.

WPA3 was released by the Wi-Fi alliance probably in 2018. Companies have been using WPA2 protocol since 2004, and the new regulations expand upon them. In order to make Wi-Fi safer and simpler for everyone, the Wi-Fi alliance works to develop new technologies , campaigns and regulations. Manufactures need a year or two to make their goods in line with company standards, which are usually released with considerable fanfare.

The purpose of WPA3 is to increase wireless network security. Compared to WPA2, it offer significantly better data protection for data travelling over home and business Wi-Fi networks. Better protection for weak passwords, encryption for open and personals networks, and enhanced security for networks used by business are among the updates to WPA3.

What Differentiates WPA3 from WPA2?

By now, a few years after WPA3 was first announced in 2018, you have probably aware of the term. Additionally, you might have even found it in the setting menus, depending on how recent your Wi-Fi router and devices are. What exactly is the difference between WPA2 and WPA3, and why would you think about utilizing WPA3?

Why does WPA3 have any important?

WPA3 is still the industry standard for wireless security and is a requirement for Wi-Fi certified devices. WPA3 is a general advancement over WPA2, its predecessor. By permitting stronger authentication than WPA2, offering greater cryptographic strength, and increasing the resiliency of critical networks, WPA3 aims to enhance Wi-Fi security. Because Wi-Fi network are used intended and secured differently in different environment the more recent standard also offer unique benefits for personal and business use. For instance, WPA3, personal network provide better defiance against password guessing attempts, whilst WPA3 enterprise network enhanced network security procedures

WPA2 vs WPA3: What’s the Difference? Complete Security Comparison

Wi-Fi networks are secured by two separate generations of wireless security protocols called WPA3 (Wi-Fi Protected Access 3) and WPA2 (Wi-Fi Protected Access 2). The following are some of the main differences between WPA2 and WPA3.

What is WPA2?

The most popular wireless security protocol since its introduction in 2004 is WPA2. A 256-bit encryption key is provided, and network traffic is secured using the advanced encryption standard (AES) method. WPA2 does, however, have several vulnerabilities. Researchers found a vulnerability called a key reinstallation attack (KRACK) in 2017, which enables hackers to intercept and alter data being sent over a network. This has been fixed by hardware and router makers, but it still underlines how important it is to keep routers and other devices updated with the latest security updates.

What is WPA3?

The most recent and safest Wi-Fi-protected access security protocol is WPA3. WPA3, which was released in 2018, increased security in both user and corporate modes. It fixes the vulnerability known as KRACK(key installation attacks) that was found in WPA2 in 2017.

WPA2 Vs WPA3 | Difference between WPA2 and WPA3

  • WPA2 stands for Wi-Fi Protected Access 2, and WPA3 stands for Wi-Fi Protected Access 3.
  • WPA2 is a security protocol developed by the Wi-Fi Alliance in 2004 for use in securing wireless networks, designed to replace the WEP and WPA protocols, while WPA3 was released in 2018. WPA3 is the next generation of WPA and has better security features. It protects against weak passwords that are reasonably guessable and easy to break.
  • WPA2 is recommended over WEP and WPA and is more secure when a Wi-Fi-protected setup (WPS) is disabled. It is not recommended over WPA3. On the other hand, WPA3 is more secure and recommended than WPA2.
  • WPA2 uses the AES standard rather than the RC4 stream cipher, in contrast to WEP and WPA. WPA's TKIP is replaced by CCMP. In contrast, WPA3 is 128-bit encryption in WPA3 personal mode (192-bit in WPA3-enterprise) and forward secrecy. WPA3 also replaces the pre-shared key exchange with simultaneous authentication of equals, a more secure way to do an initial key exchange.
  • Even on public Wi-Fi networks, WPA3 provides customized data encryption for any device linked to the network. This improves security and privacy as every device has a unique encryption key. With WPA2, the encryption key is shared by all connected devices on the same network.
  • WPA2 mandates support of PMF since early 2018. Unpatched firmware on older routers might prevent PMF from working. Protected management frames (PMF) must be used according to WPA3.
  • WPA2 does not provide security for public networks; WPA3 introduces the enhanced open security mode, which uses opportunistic wireless encryption (OWE).
  • WPA2 uses the pre-shared key (PSK) technique, which requires the user to submit a common password to authenticate and access the network. The dragonfly protocol, also known as a simultaneous authentication of equals (SAE) and introduced in WPA3, offers stronger protection against offline dictionary and password-guessing attacks.
  • WPA2 aims to provide better protection against attack and improve overall network security. WPA3 addresses some security vulnerabilities and weaknesses found in WPA2, including the KRACK (Key Reinstallation Attack) vulnerability.

What is WEP?

What is Wired Equivalent Privacy (WEP)?

An IEEE standard security technique for wireless 802.11 networks was released in 1997 and is called wired equivalent privacy (WEP). It was quickly considered to be extremely inadequate and replaced by WPA, WPA2, and 802.11i. The purpose of WEP is to guard against cyberattacks and encrypt wireless communications. It is a very weak authentication mechanism even making it easier for an attacker to find out the encryption key. As a result, the specification did away with the WEP authentication.

With WEP, data is encrypted using a hexa decimal 64 or 128-bit key. Because this is a static key, all traffic is encrypted using a single key, no matter the device. A computer connected to a network can exchange encrypted communication while keeping the content hidden from outsiders via a WEP key. To establish a connection to a network with wireless security enabled, you need this key.

Initially, WEP was able to prevent main-in-the-middle attacks, which was one of its primary objectives. Over time, however, a number of security vulnerabilities were found in the WEP standard, even with protocol modification and larger key sizes. In 2004, the Wi-Fi alliance formally deprecated WEP due to security flaws. Although it is occasionally still in use, WEP security is now regarded as outdated. This is either because devices that enable encryption are too old to support it or network managers haven't updated the default on their wireless routers.

What is x86 Architecture?

What is x86 architecture?

The term "x86 architecture" refers to an instruction set architecture (ISA) series for computer processors. The Intel Corporation developed the x86 architecture, which describes how a processor handles and executes different instructions received from software programs and operating systems (OS). Because of the complex instruction set computer (CISC) design of Intel x86 processors, there are more special purpose registers than general purpose registers. The ISA version is indicated by the x in x86. 

Microsoft Win32 takes advantage of the x86 CPU in 32-bit flat mode. In this guide, the flat mode will be the sole topic we cover.

Features of x86

  • The computing architecture is complex instruction set computing (CISC).
  • x86 has less memory but more available resistors.
  • To complete complex instructions, numerous cycles are needed.
  • Make use of data execution prevention (DEP) software.
  • designed to handle complicated addresses while utilizing fewer pipelines.
  • The hardware method optimizes system performance.

Application of x86

  • It is better for emulation.
  • parts of cloud computing.
  • used in video game consoles.
  • x86 CPUs and OS systems still power a large number of personal computers worldwide.
  • The majority of older programs and applications use 32-bit architecture.
  • Because 32-bit is compatible with older audio equipment, it is still popular in audio production.
Limitation of x86
  • The amount of accessible memory on it is restricted.
  • 64-bit OS is required for modern CPUs.
  • 32-bit operating system programs are no longer developed by vendors.
  • In comparison to x64, the processing performance is slower.
  • The RAM that is available to all devices on the system is shared, meaning that the OS and apps have even less capacity.
