What is the difference between CC and BCC when sending an e-mail? In the current era, Email is one of the best and most preferred modes of communication for both small and large organizations. The term Cc (Carbon Copy) and Bcc (Blind Carbon Copy) are used in the Email to securely send and receive the information via Email. Cc stands for Carbon Copy. It is used in the Email to send the carbon copies of the Email to the recipients. In Cc , all recipients are able to see a list of all other recipients.  ◦ Cc is used when we want to send an Email to someone without addressing them personally.  ◦ Cc is used for group communication.  ◦ It keeps all management and employees in the loop even if an Email doesn't concern them directly.  ◦ Cc is used when we want to receive the responses from the associated email recipients.  ◦ Cc is used when we want to inform other recipients about the email. Bcc stands for Blind Carbon Copy, which is similar to Cc. It is also u...

When it comes to Books and Movies, what’s a Prequel, Sequel, and Spinoff? In the world of books and movies, a sequel, prequel, and spinoff are all different types of follow-up stories related to an original work. Here's an in-depth explanation of each: Sequel: A sequel is a story that continues the events of the original work. It is a new installment that picks up where the previous one left off, continuing the storylines of the characters, themes, and plot. A sequel can be set immediately after the original work or can take place years later. The purpose of a sequel is to expand on the original story, to deepen the characters, or to explore new ideas. Example: "Harry Potter and the Chamber of Secrets" is a sequel to "Harry Potter and the Philosopher's Stone." Prequel: A prequel is a story that takes place before the original work. It is a new installment that explores the backstory of the characters or the events that led up to the original story. A pre...

What’s the Difference Between a Memoir, a Biography, and an Autobiography? The three primary formats used to tell a life story are a biography , an autobiography, and a memoir. Simply put, a biography is the life history of an individual, written by someone else. An autobiography is the story of a person’s life, written by that person. And a memoir is a collection of memories written by the person themselves. A biography, also called a bio , is a non-fiction piece of work giving an objective account of a person’s life. The main difference between a biography and an autobiography is that the author of a biography is not the subject. Biographies include details of key events that shaped the subject’s life, and information about their birthplace, education, work, and relationships. An autobiography is the story of a person’s life written by that person. Because the author is also the main character of the story, autobiographies are written in the first person. The purpose of an auto...

What are G ,E ,H ,H+ ,LTE , 3G, 4G, 5G displayed on your smartphone when you switch on mobile data for internet? In mobile communications, frequently, the terms GSM, GPRS, EDGE, UMTS, HSPA and LTE appear. These terms refer to different standards of data transfer and are noticeable for the mobile phone user mainly. First, there was only the GSM network , then there were improvements of the GSM network , finally the newer and faster UMTS network , and again improvements of it. The faster UMTS network is not yet available everywhere, so, often you have to go over the older and slower GSM network even today. About the abbreviations on your smartphone notification bar. G stands for GPRS and is the slowest standard, used is the GSM network (2G) . E is an extension of GPRS, it is called EDGE and it is correspondingly a little faster, but still uses the old GSM network (2G). EDGE is used to refer to 2.5G 3G (3rd Generation) stands for UMTS and is the successor to the GSM network ...

Why do you get Boogers in your Eyes? The scientific name for eye boogers is rheum. Rheum is made up of mucus, skin cells, oils and dust. The rheum that comes from the eyes and forms eye boogers is called gound , which you may know as eye sand, eye gunk, sleep dust, sleep sand, sleep in your eyes. When you're awake, gound doesn't cause any problems. Your eyes produce mucus throughout the day, but a continuous thin film of tears bathes your eyes when you blink, flushing out the rheum before it hardens in your eyes. When you're asleep  and not blinking, eye discharge collects and crusts in the corners of your eyes and sometimes along the lash line, hence the term "sleep in your eyes." Eye discharge is a common symptom of conjunctivitis. In addition to conjunctivitis, there are many eye infections that cause abnormal eye discharge. These include: eye herpes (a recurrent viral eye infection) , fungal keratitis (a rare but serious inflammation of the cornea) an...

 The Hard Truths About Life that No One Tells You. 1. Success is simply a pile of failures stacked together as a ladder to test your faith, determination, passion, persistence, and resilience, but more importantly, to make your success valid. 2. When people cheer you up, don't rejoice because of that. Rejoice because you have seen your destiny. There are those who rejoice with you but deep inside, they are praying for your downfall. 3. No number of self-help books, inspirational videos, and motivational seminars can change a person unless they are willing to sacrifice all of their bad habits. 4. The majority of people are not living happily. They are actually living other people’s dreams and pretending that they are happy. 5. Nothing is permanent. Even the fire of a blissful love affair that started off as a fiery tale begins to dim the moment you encounter the rough, unmerciful, and uncompromising patches of life. 6. Everybody is selfish to the extent that nobody will see their he...

How does a Parabolic Antenna work? An antenna has an active element that picks up or sends out radio waves. This active element is the one connected to the electronic circuitry. An antenna is essentially a transducer. It converts electrical energy into electromagnetic energy as as way of coupling the electronic circuit to the medium of communication called free space. Dish antenna is curved so that all the radiation that strikes it is reflected to converge at one single point - its focus - where the amplifier or the receiver is placed. It is a parabolic reflector - a curved surface with the cross-sectional shape of a pararabola that directs the incoming waves to the focal point. This enables the maximum signal strength. The same reason why a concave mirror is used in a reflecting telescope; it gathers all the photons and focusses it to one single point. The satellite is situated in an orbit about 22,000 miles, or 36,000 km for those who like to count in tens, up. At this point the orb...

Why does banging your Elbow give you an Electric Shock? The spot where it occurs is called the funny bone. The funny “bone” is actually a long vine of a nerve called the Ulnar Nerve. Between the humerus and the forearm there exists a void, what is called the cubital tunnel , where the nerve is the most vulnerable as at the elbow the nerve is less protected by muscle, fat and skin and can be easily bumped. When you hit your funny bone against something, the unprotected nerve is pressed against the bone. It is the squeezed or irritated ulnar nerve that spouts the waves of pain, emitting the “electric shock” . The waves terrorize the regions innervated by the nerve: the forearm, the pinkie and half of the ring finger. A pinched nerve can start in several places throughout your body, but usually in the joints. When a pinched nerve is in your elbow, it can leave your arm and hand feeling sore, numb, or weak. Pain and tingling sensations to shoot down your forearm. People often describe t...

  What causes Bones to make popping sounds? To understand what happens when we 'crack' our knuckles , or any other joint, first we need a little background about the nature of the joints of the body. The type of joints that we can most easily 'pop' or 'crack' are the diarthrodial joints . These are our most typical joints. They consist of two bones that contact each other at their cartilage surfaces; the cartilage surfaces are surrounded by a joint capsule. Inside the joint capsule is a lubricant, known as synovial fluid , which also serves as a source of nutrients for the cells that maintain the joint cartilage. In addition, the synovial fluid contains dissolved gases, including oxygen, nitrogen and carbon dioxide. The easiest joints to pop are the ones in our fingers (the interphalangeal and the metacarpophalangeal joints) . As the joint capsule stretches, its expansion is limited by a number of factors. When small forces are applied to the joint, one factor...

  What is Cellular Jammer? How does it work? A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting them. Jammers can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected, such as entertainment venues. It might be hard to follow this process without first understanding cell phone signals. Cell phones work by sending signals to cell phone towers. The cell tower that receives the signal depends on the cell phone’s location. Cell towers divide their workload by honing in on specific areas. So when you travel with your cell phone, your cell phone sends signals to different towers.  The jamming device work...

  ​​How does a Cellphone Vibrate? Among the many components inside the phone is a small motor. The motor is built in such a way that it is partially off-balanced. In other words, a mass of improper weight distribution is attached to the motor's shaft/axis . So when the motor rotates, the irregular weight causes the phone to vibrate. Rotating unbalance is the uneven distribution of mass around an axis of rotation. A rotating mass, or rotor, is said to be out of balance when its center of mass (inertia axis) is out of alignment with the center of rotation (geometric axis). Unbalance causes a moment which gives the rotor a wobbling movement characteristic of vibration of rotating structures. There are two basic types of vibration motor: An eccentric rotating mass vibration motor (ERM) uses a small unbalanced mass on a DC motor , when it rotates it creates a force that translates to vibrations.   A linear resonant actuator (LRA) contains a small internal mass attached to ...

  How does a Lie detector work? A lie detector, also known as a Polygraph test works by detecting physiological changes due to a psychological stimulus. The earliest version of the instrument was developed in 1921 by John Larson who combined changes in respiration, heart rate and blood pressure as physiological changes that occur when a person is lying. The modern polygraph is a technologically advanced system that measures the same parameters with high levels of accuracy with computers.  The theory behind lie detection tests are that when people are lying they experience a different emotional state when compared to telling the truth, it is believed that in high stake scenarios, being anxious or afraid of getting caught when being guilty of an offense manifests physiologically. This is due to the sympathetic nervous systems response of flight and fight that releases hormones which increase heart rate, elevate body temperature and respiration.  The term polygraph origi...

How does a Ball Point Pen work? A Ball point pen is a pen that uses a small rotating ball made of brass, steel, or tungsten carbide to disperse ink as you write. All of the pens that preceded the ballpoint -- whether quill, metal or fountain -- used a watery, dark india ink that fed through the pen using capillary action. The ink can flow unevenly. The ball is located in between the ink reservoir and the paper by a socket , and while it's in tight, it has enough room to roll around as you write. As the pen moves across the paper, the ball turns and gravity forces the ink down the reservoir and onto the ball where it is transferred onto the paper. It's this rolling mechanism that allows the ink to flow onto the top of the ball and roll onto the paper you're writing on, while at the same time sealing the ink from the air so it does not dry in the reservoir.

What Is The Metaverse? The coining of the term “Metaverse” is credited to author Neal Stephenson from his science fiction novel “Snow Crash” in 1992. The novel envisioned the next internet iteration where lifelike virtual avatars connect with one another through virtual reality environments and realistic 3D buildings. Since then, technology advancements have enabled the beginning development of the metaverse with a combination of computers, wearable technology, and machinery, such as virtual reality headsets, augmented reality glasses, motion sensors, and game consoles where users are able to “live” within a digital universe. Our current contemporary internet experience is two-dimensional where you scroll through and browse everything on a screen. The metaverse on the other hand is 3D , allowing you to “walk” through the two interwoven worlds via connected glasses or headsets that allow you to construct or participate in any universe you desire in the digital world. In si...

What Do We Actually Smell When It Rains? When those first fat drops of summer rain fall to the hot, dry ground, have you ever noticed a distinctive odor? Of course rain itself has no scent. But moments before a rain event, an “earthy” smell known as petrichor does permeate the air. People call it musky, fresh, generally pleasant. Petrichor is the term coined by Australian scientists in 1964 to describe the unique, earthy smell associated with rain. It is caused by the water from the rain, along with certain compounds like ozone, geosmin, and plant oils. Petrichor is a combination of fragrant chemical compounds . Some are from oils made by plants. The main contributor to petrichor are actinobacteria. These tiny microorganisms can be found in rural and urban areas as well as in marine environments. They decompose dead or decaying organic matter into simple chemical compounds which can then become nutrients for developing plants and other organisms. A byproduct of their activity is ...

  What Are Olympic Gold Medals Actually Made Of? If you’ve watched the Olympics, you may have wondered to yourself: Are Olympic medals real gold? And if they are, how much is an Olympic medal worth if an Olympian chose to sell theirs? We break down those answers ahead. Olympic gold medals have some gold in them, but they’re mostly made of silver . According to the International Olympic Committee (IOC) , gold and silver medals are required to be at least 92.5 percent silver . The gold in gold medals is in the plating in the outside and must consist of at least 6 grams of pure gold . As fans may have noticed, many gold medal winners will pose with their medal in their mouth on the winner’s podium , as if they’re about to take a bite out of it. While real gold dents , viewers won’t see much of a difference in Olympic gold medals as they’re made of mostly silver. Silver medals, on the other hand, are made of pure silver, while bronze medals are 95 percent copper and 5 percent zinc....

  What is the difference between Venom and Poison? Venom and Poison are both toxic substances. Still, some animals are called venomous and others are poisonous. The only difference between being called poisonous or venomous is in the way these animals deliver the harmful substance. Venom: When animals like snakes use their sharp fangs to bite into the flesh and let the toxic substance move into the body of their prey,  through the punctured skin, they are called venomous animals. To deliver venom an animal has to use tools like fangs or stingers. Poison: Poison is something that can get inhaled, ingested or seeped into the skin directly. For example, if you accidentally touch a brightly colored poison dart frog, you will transfer the toxins it secretes from its skin, to your own skin. And then the poison will seep into your blood stream.

Why do Passports only come in Four Colors? Red, green, blue and black are the shades that control the universe of passports and all of these have a good reason for it. There are some reasons to attribute to the choice of passport colors. The colors of the passports are limited, nations keep testing with the shades of these four main colors that may be attributed to "many possible scenarios." Blue: Countries having blue colored passports are supposed to be the part of the so-called 'new-world' League of Nations. These nations are India, North America, South America and Australia among others. Red: Red is supposed to be the color of the communist movement in all over the world. This color usually belongs to countries, which are known for having a communist history or still have its influence. Key examples of this type are China, Russia Serbia and Latvia. Green: As per the Business Insider, religious faiths play a role in the color of the passport. This is the ...

  How do Spiders make Web?  Spiders produce silk threads to build their webs. The silk is produced in silk glands with the help of the spider's spinnerets. Spinnerets are special organs that allow the spider to decide what type of thread it needs for the web. The silk threads can be thick or thin, dry or sticky, beaded or smooth. The threads a spider uses to construct its web begin as liquid, but they dry quickly in the air. When a spider begins a web, it releases a silk thread. It anchors the thread to some object — a branch, a corner of a room, a doorframe — wherever it builds its web. As the spider moves back and forth, it adds more threads, strengthening the web and creating a pattern. Lines that go from the center of the web outward are called "radial lines." They support the web. Threads that go around and around the web are called "orb lines." When a spider catches prey in the sticky strands of its web , it approaches the trapped insect and uses its ...

  Why Does Body Temperature Rise During Fever? We have three groups of neurons in the hypothalamus , at the base of the brain, that are responsible for regulating body temperature: a hypothalamic thermostat that monitors skin temperature (via incoming signals from nerve fibers) and blood temperature ; a heat-promoting center that raises body temperature; and a heat-losing center that lowers body temperature. An infection stimulates the immune system to produce chemicals called endogenous pyrogens. These and prostaglandin E2 raise the set point of the hypothalamic thermostat ( like turning up the thermostat in your house ). The heat-promoting center constricts blood vessels near the skin surface so more heat is retained in the body, and if that’s not enough, it stimulates shivering to generate more heat, until the body temperature reaches the new set point. The elevated temperature makes it harder for bacteria and viruses to multiply, so the immune system can overwhelm these pa...
