Below, we discuss some of the main benefits or advantages of mobile phone:

1) Easy Communication

Although the primary purpose of mobile phones was to connect people over calls, modern phones have evolved in such a way that they can now be used for texts, chats, and even video calls wirelessly all over the world. One of the most important benefits of having a mobile phone is that we are always connected to our professional email account and can access and reply to others as and when needed, from anywhere.

In addition to basic communication options, mobile phones are widely used for social networks such as Facebook, Instagram, Twitter, etc. Most such social platforms allow communication between one or more people across the world. These social media or social network platforms are equipped with rich features and usually allow transferring of text, images, videos, and other media files.

2) Self Learning & Education

Students can also take advantage of mobile phones for their studies during online classes and for self-learning through internet research. Thus, if used properly, mobile phones can be really helpful in the field of education. Unlike books, students do not need to go through the index, then chapter, then page, and then passage to find any specific little information about any topic. Instead, they can simply use their mobile phone and search for relevant topics on the internet instantly, reducing their time.


Despite self-learning and online classes, students or candidates can also fill up various forms using their mobile phones. Not only educational material, but people can also avail mobile phones to view any recent news, weather updates, finance-related information, and much more.

3) Online Banking & Payments

Other essential benefits of mobile phones include self-banking and cashless payments. Presently, people can open their bank accounts digitally even from their homes using mobile phones. They can transfer money, check transactions and access their respective bank accounts' details on mobile using the bank's website or application. Most of the banking operations can now be performed by the user without the need of a bank employee.

Due to mobile banking, paying through mobile phones has also become so easy. People do not need to carry much cash and even debit/credit cards in urban areas. People in most countries can pay merchants directly through their bank accounts using their mobile phones. If people require cash from an ATM, they can also redeem it themselves using specific ATMs and their mobile phones, without the need for a debit/credit card.

4) Easy Booking & Shopping

With mobile phones, it has become so easy to book, or shop for various items online. Due to advancements in technology, people can book or shop directly from their homes. They can get the desired goods delivered to their homes. The payment can be made offline on the spot or online as prepaid.

Not just movies, mobile users can book buses, trains, flights, and even taxis or cabs to travel from one destination to another. When it comes to shopping, people can visit related websites or use applications to select or find items such as toys, clothing, packaged foods, cooked foods, medicines, dairy products, vegetables, and many more. They can order them to get them to their doorstep. Home services for Repairs and Maintenances are also available on mobile phones with a few clicks.


5) Entertainment Hub

Mobile phones are considered to be fully packed devices for entertainment. This is one of the biggest advantages of mobile phones which are experienced by people of all ages. With the use of the internet, there is no limit to the entertainment options on mobile phones these days. People can enjoy music, and watch video clips or movies to pass their time. Above all, even mobile phones are equipped with the Live TV feature, allowing people to watch their favorite TV channels anywhere.

Another great advantage of mobile phones in terms of entertainment is gaming. Since mobile has become powerful, gaming has also advanced. Nowadays, there is a wide range of mobile games with different features in different categories like shooting, adventure, sports, etc. With games like PUBG and BGMI, it has been seen that mobile gaming has reached a completely different level these days.

6) Income Source & Investments

Some people use their mobile phones to maintain a luxurious lifestyle. They use mobile phones to invest and earn a good amount of money. Business promotion and brand awareness have also become easier with mobile phones and social media platforms.

Generally, most people invest in the stock market, mutual funds, cryptocurrencies, and even gambling to earn extra money. For many families, mobile phones are also the primary source of income. Many people are earning good money from YouTube earning, advertising and promotion.

7) Additional Gadget

Due to the increasing usage and dependence on mobile phones, they are equipped with many additional features that help us to use our mobile phones as other gadgets or devices. Almost every modern mobile phone is equipped with a camera and a flashlight. While a camera helps us to take pictures or record videos anytime, a flashlight enables us to use a mobile phone as a flashlight in the dark or at night.


Apart from this, mobile phones also come with a clock, timer, stopwatch, alarm, notebook, and GPS. Along with devices like IR blaster, these days’ mobile phones can also be used as remotes for smart home appliances like TVs, air conditioners, lights, fans, etc. Innovative companies like Asus are focusing on enabling people to experience mobile phones as real gaming consoles.

Disadvantages of Mobile Phone

Disadvantages usually come with advantages. It is generally seen that if something has advantages then there are also some disadvantages. Similarly, despite many advantages, the increasing use of mobile phones is creating many problems for the people and the environment. Following are some of the main problems or disadvantages of mobile phones:

1) Addiction & Distraction

Since mobile phones are essential parts of human life, everyone carries them, be it at home, offices, or while traveling. Many people, especially youth and children, are getting addicted to mobile phones and they like to spend their precious time using their mobile phones in playing games, listening to music, watching movies, etc. This way of connecting with mobile phones is increasing which is dangerous for people as it is wasting time, distracting from goals, and even causing health issues.

Mobile phones are not only becoming addictive but also becoming a means of distraction for people. They can distract people from their work, study, and other essential purposes. It has been seen in most of the children that whenever there is a sound from the mobile phone or a notification, their attention is easily diverted during the studies. It is very common to see that mobile phones often show notifications for new software and games to encourage people to try them, which easily distracts people from their goals.


2) Health Problems

Mobile phones not only create stress, increase anxiety, or disturb the peace of mind, but also affect health physically very dangerously. Constantly looking at a mobile screen can lead to frequent headaches, which can also affect the eyesight over time. Children using mobile phones often feel low vision problems and have to use glasses at a very young age.

Apart from eye problems, mobile phones also cause problems like ear pain and hearing loss. This is usually due to prolonged calls because the sound causes the eardrum to vibrate. Instant high and low-pitched voices often cause problems in the ears. Despite this, using the phone continuously in certain body positions can lead to back pain and body aches as we do not move much, blocking blood circulation. It also gives overall results in the form of laziness on regular days.

3) Isolation

With the increasing use of mobile phones, people do not have time to talk to others. They usually like to spend their time alone and use their mobile phones for gaming, chatting, listening to music, watching movies, etc.

Although many people feel good about chatting on social media using their mobile phones, they are not very social in their personal life when interacting face to face. Due to their lack of social interaction and communication skills, they often prefer to live in isolation. It also affects their career to some extent in the future.


4) Bullying

Bullying means posting, sharing, or sending negative, false, abusive, and/or threatening content about or to another person using digital means like mobile phones. It is widely observed that children become most aggressive and use mobile phones to bully others online. It has been observed that children who have mobile phones often bully those who do not have mobile phones. After verbal bullying over the phone, children can get involved in verbal and even physical fights, which can be dangerous.

5) Privacy & Security Concern

Mobile phone is an integral part of daily life routine. People use mobile phones to store their personal and financial data including debit/credit card details, net banking credentials, addresses, mobile numbers, etc. Breaching into the phone can make all such details accessible to hackers, resulting in loss of money, personal data, and even reputation.

Apart from this, people, these days use mobile phones for secretly taking pictures, and recording audio or video of others. Such an image or video can be misused in various ways. The most common examples include using images to create fake pornographic material and then blackmailing the corresponding individuals. In addition, people can use the images to create fake identities on social media to spread rumors. Thus, mobile phones have a major drawback for security and privacy.

6) Life Threats

Mobile phones can sometimes be life-threatening, which means they can put one's life in danger. There have been many such cases where people lost their lives due to mobile phones. The most common scenario that we can often see is people using mobile phones while driving, or crossing the road, which causes accidents in most of the cases. In this way, people using their phones not only put their lives at risk but also put the lives of others at risk.


Apart from road accidents, over time some other specific cases have been registered where mobiles have proved to be life-threatening. Cases have been registered in which it was claimed that mobile batteries exploded and people were harmed. Apart from this, there have also been mobile applications like Blue Whale, Momo, etc., due to which youth and children committed suicide or killed others. Moreover, mobile theft is very common in many cities, causing fighting and life-threatening.

7) Bad Environmental Impact

Researches in the past have shown that mobile phones have become the most harmful of all electronic devices, causing huge emissions into the environment. Most of the emissions impact comes from the production chain, which is increasing day by day. On average, manufacturing a new mobile phone uses almost the same amount of energy as it consumes while using it every day (including charging) for 10 years. Thus, its production is more harmful than using it in daily life.

Mobile phones require various elements, including metals that are usually obtained through mining processes. The process of mining, refining, manufacturing, and transportation around the world typically involves massive amounts of harmful emissions, releasing more carbon into the air. With the increasing number of mobile phones around the world, the overall environmental impact of mobile phones has also increased significantly. Mobile phones, especially smartphones, produce more greenhouse gases than any other electronic device or component.


Summary

Although there are many disadvantages to using mobile phones, they are widely used all over the world. It is our responsibility to avoid unnecessary use of mobile phones and try not to change our mobile phones frequently. It is up to the users to mitigate the effects of mobile phone damage to some extent. Apart from those discussed above, mobile phones have many other advantages and disadvantages.

Advantages and Disadvantages of Online Classes

It has become very common for students to take online classes these days. Not only as their free choice for personalized online courses but students are also forced to take online classes at schools, colleges, and universities, especially after the pandemic COVID-19, which has previously caused the lockdown in many countries for days and even months.


Online classes are a form of distance education by a teacher to one or more students over the Internet using computational devices such as mobile phones, tablets, laptops, or computers. It is also known by other words like online learning, e-learning, digital education, etc. The trend of online classes is still widely used; however, there are some advantages and disadvantages of online classes that we must know.

In this article, we have covered both the advantages and disadvantages of online classes. Let’s check them out:


Advantages and Disadvantages of Online Classes

Advantages of Online Classes

Below, we discuss some of the main benefits or advantages of online classes:

1) Convenient, and Flexible

Online classes are extremely convenient and flexible for students and teachers in various ways. The timings and schedules for classes can be adjusted as per the flexibility of both. Both students and teachers have access to online classes from the comfort of home. Hence, students need not carry their heavy bags full of books and travel to attend in-person physical classes. 

Online classes, being conducted on computational devices, can be recorded and shared. This makes it easier for students to access learning materials multiple times in the future as per convenience. Also, the availability of a wide range of options like images, videos, and PDFs makes learning easier for students and teaching for teachers or instructors.

If for any reason the teacher is not present at the scheduled time of the digital class, students are free to use this time for other work, be it study, play, or homework. Similarly, if the student has an important task at the scheduled time, he/she can request to reschedule the class or access the digitally shared content or recorded class videos in free time.

2) Less in Cost

Online classes are more affordable or cost-effective than traditional offline classes. The significant impact of cost savings relates to travel expenses or parking expenses. With offline classes, schools and colleges often charge irrelevant money in the name of maintenance, functions, seminars, projects, sports, etc. Due to digital classes, students usually do not need to pay such unnecessary amounts while studying.


Nowadays mobile phones and internet connections are available in almost every middle-class family. Students can easily join their online classes using these two sources. With online classes, teachers can teach students using information from the Internet, reducing the need for so many books. It also helps in saving a good amount for financially weak students.

Since online classes are taken from the comfort of homes, students are usually not forced to wear any specific school uniform. Even though some schools ask students to wear uniforms in digital classrooms, parents are free to buy the uniforms on their own. They are usually not forced to obtain uniforms from schools or affiliated vendors. It helps the parents to save some money which is earned by the schools as commission.

3) Maximum Attendance

With the comfort of home and parental guidance, students typically attend most online classes. Even if the student is not at home, he/she can attend the online class on a mobile phone while traveling or from other places. This helps in increasing the attendance percentage, resulting in a somewhat higher education rate among the students.

Apart from this, it has also been observed that when forced to go to schools/colleges to attend offline classes, many students bunk their classes and go to play sports. Online classes have also reduced class bunk scenarios.


4) Better Attention

Unlike traditional in-person classes, online classes are often conducted with a limited number of students. With offline classes, it is often seen that back-benchers do not get the proper attention of a teacher and even a proper view of the contents being taught by a teacher on board. This is not the case in online classes. In online classes, every student has equal access to the same content.

Since every student is treated almost equally, students do not feel afraid or ashamed to ask questions and clear their doubts in online classes. Additionally, students also get the availability to communicate with the teacher over text, chat, and phone calls. This allows students to ask their questions personally at any time, even without informing other students.

The more attention is given to each student, the better the result of education.

5) Limited Competition

Since the number of students in individual online classes is often limited, there is generally less intense competition among students. This to some extent helps the students to feel less stressed, and more relaxed, helping them boost their self-confidence. Due to limited competition, students pay more attention to their studies and remain mentally fit.

Even though the competition is limited in digital classrooms, students with a focused mindset always try to be on top. In this way, students take advantage of internet access from home to enhance self-study and expand their knowledge to beat the competitors.

6) Tech-Learning

Since online classes are conducted over the Internet using computational devices like computers, laptops, smartphones, and tablets, teachers as well as students are forced to learn how to operate these devices. With constant focus and practice, they soon learn to handle such devices and become tech-savvy with digital learning.


Being tech-savvy with online classes, students and even children are often seen guiding their parents or elder family members to operate the devices like mobile phones, tablets, laptops, etc. This can be considered an essential advantage as most of the jobs in today's technological era require tech-savvy employees.

Many teachers and even students have created their accounts on social media platforms including YouTube. With a sufficient number of followers and unique content, they can also earn decent amounts of money on the internet.

7) Worldwide Connectivity

With online classes, students are not limited to their individual school or university. They can learn things or educate themselves from any specific school or university in the world, thereby making education accessible to all.

Getting digital education is very helpful for those students who are thinking of taking a degree abroad but there are some financial problems or restrictions on traveling there. They can contact the respective college/university and attend online classes from home. In addition, digital learning has provided a better education for students in many global rural areas where there are no professional teachers.

Disadvantages of Online Classes

The increasing use of online classes is causing various problems in society. Following are some of the main problems or disadvantages of online classes:


1) Lack of Focus

It becomes difficult for many students to focus on their learning during online classes. They often struggle to focus on the screen for long periods of time. Many reasons may distract students from studying online as digital classes are conducted through computational devices such as smartphones, tablets, or laptop computers.

As we all know, computational devices are the primary source of entertainment these days, be it for music, videos, movies, or games. Moreover, modern devices can easily handle multiple tasks at a time. Such features often distract students while studying and attract them to entertainment content.

Apart from this, another primary concern for most of the students is the performance of their devices during the online class. Older or low-end devices often perform slowly due to heavy loads which cause irritation during virtual classes. Also, slow internet causes trouble during class. In addition, these devices can receive phone calls during the study, send regular notifications from social apps and display random ads, etc. Due to all these reasons, students get distracted from their subject studies.

2) Health Problems

With online classes, students are constantly forced to focus on the device screen for long hours. Looking at the screen of the device makes the eyes dry and causes eye strain, headache, etc. This often leads to weak eyesight in the future. This is the reason why many children nowadays prefer eyeglasses while studying.


In addition, prolonged and improper use of computational devices can negatively affect human health in many other ways. When sitting in front of the screen continuously for a long time, students may feel pain in areas of the body like the neck, back, waist, etc. This can result in serious injury over time with comparatively prolonged use.

3) Lack of Social Skills

The biggest disadvantage of online classes is considered to be the lack of social skills. When students are completely dependent on online learning, they spend most of their time with computational devices. They become familiar as well as addicted to these devices over time and start spending a lot of their time alone at home. This sometimes creates a nature to live alone or in isolation.

Both teachers and students can feel a sense of isolation with continuous classes online for a relatively long period. This is usually due to little to no physical communication from person to person. This not only removes cooperative skills but also does not create socialization skills. In such a situation, people are unable to share small problems with others and often feel depressed.

4) No Practical

Online classes are not effective for all subjects and streams. Many fields, including science, technology, engineering, medical science, and many other disciplines, require practical or hands-on learning. In such situations, instructors need to use certain equipment in specific areas such as the laboratory to properly teach the particular concept.

Thus, one cannot clearly teach or learn anything practical with online classes. However, such practical knowledge is essential to develop certain skills in specific streams.


5) No Discipline

It is often seen that some students do not respect their instructor or teachers during online classes. They are also not afraid of teachers and joke or talk unnecessarily during class. Additionally, some students take it to a whole new level. They even cheat in online exams as teachers cannot physically supervise them. As a result, some students do not learn discipline while studying online.

Also, when students go to offline classes, they usually learn to sit among people, interact with them, respect each other, work as a team, etc. They become friendly with such an environment of sitting for long periods at some other place than home. This, in the future, helps the students to adjust easily to the corporate environment during their job. However, students taking online classes don't practice sitting in such an environment which could be problematic in future jobs.

6) Online Frauds

Although there are many benefits to using computational devices and the Internet, some people take advantage of it to do a variety of frauds to make money or to bully people. Students (especially children) can easily fall into such online frauds while taking online classes.

Usually, students are attracted by an advertisement giving them free prizes. These ads are often sent through some unwanted apps, or fake sites or links. Students are asked to pay a small security deposit or delivery fee to receive their huge winning prizes. Later, students often share their details including some personal and financial details. Once students get trapped, they often share the card details of their parents, causing serious financial loss to parents' earnings.

In addition, there may be many fake educational or learning courses on the internet, which students can join after paying a decent amount. There is always a security threat when one is connected to the internet. Students or children often get caught up in such online frauds.


7) Not Eco-Friendly

If online classes are promoted to the majority, there will be a significant increase in the number of computational devices in the environment. The rays and heat originating from these computational electronic devices negatively affect the atmosphere. As the number of these devices increases, the need for more and more energy increases as a higher number of devices will lead to more consumption.

It is often seen that most of the people change or upgrade their devices as soon as new technology is added or more features are provided with new devices. In such a situation, their old devices very soon become garbage and are thrown away. Most computational devices contain heavy metals, such as lead and many other toxic chemicals that can pollute soil and even contaminate groundwater.

Summary

Although online classes are extremely convenient and flexible for both students and teachers, there are some major drawbacks. Hence, it is good to conduct both online and offline classes for a fixed time duration to balance the overall impact on the students.

In this way, online classes will make technology accessible to students but for a limited period of time, helping them avoid health issues. Also, the offline classes will teach them to connect with people face to face, build discipline, and self-confidence, and respect everyone equally in real life.
