Convenience
With the use of computers, a student’s life has been made very convenient. By just using this device, students can write and research their school works online and communicate with their classmates and teachers through email or other platforms for shared discussions and knowledge. Indeed, a computer is a big help in making student life easier.

Improved student performance
Including computers as one of the learning tools in school is essential. With the use of computers, students are more likely to enjoy studying, resulting in better performance. They feel more involved and focused when computers are in use. More so, using a computer in education lets each student collaborates and, at the same time, teach them to become independent.

Fast access to research and information
Gone are the days when the only way to research and do your assignments is through the library. Today, the availability of a computer in education makes it a whole lot easier and faster to access everything you need to research. In just a few clicks, you can get all the answers you need for your school projects.

Online resources
When a student needs help in deciding a topic for their thesis or an essay, technology helps them find the relevant and the most accurate information. Whether it’s science, business, sociology, or any course with a name, the internet and computer technology provide all the latest information about finding the right thesis topic and the relevant information in justifying the choice.

Increased efficiency
Undoubtedly, computers offer increased efficiency to every student. These allow them to complete their assignments, check their grades, and make presentations even outside school hours. The flexibility and efficiency that computers give to students are worth it as there are so many things to learn.

Admissions information
When students are trying to fetch everything they can, related to the admission process and information about different universities that can help them decide which college or university to apply to, they can quickly get it over the internet. Universities and colleges have a tremendous online presence. They are there to assist students in almost everything they want, from inquiring about admissions to assisting in the application and visa processes, payment, and preparing for arrival. It has helped students and expands the reach for universities and institutions to attract the best students from around the world.

Study schedules
When students decide to choose particular courses, they need to see real-time information and updates, and technology can help them find it. This way, they can find the right timings for the course; the assignment outlines and also helps them schedule their studies accordingly.

Learn how to write an essay from selecting a topic to the final draft.

Better opportunities
Through the use of technology and the internet combined, students come across a lot of different opportunities. This way, they can find detailed information about them, see what fits best for their aspirations and success, and decide accordingly. They can also interact with fellow professionals through messengers and learn from their experiences.

Easy communication
Communication has been made easier through the use of computers, especially for those students who are living far from their families. Instant messaging, emails, live updates, and sharing tools help students get in touch with their loved ones easily, even if they are away from home. Simply put, computers and the internet make the world intact despite the distance.

Better rate of learning
What used to take years to study can now be completed within moments due to technology, especially in the sciences. Today, there is software that provides a simulation of plant growth under certain specified conditions. This type of virtual simulation is endorsed by the US government’s National Library of Medicine/National Institutes of Health as a fantastic aid in researching growth modeling. It could be concluded that technology enables students to learn more in a much shorter period because of virtualization models.

Visualization tools
For many students, math has always been difficult because they have trouble visualizing the concept being taught. Now there are programs designed to let students see relationships on the computer screen in front of them. Pardon the pun, but they literally get the picture. A team from Utah State University has assembled a long list of math tools on the National Library of Virtual Manipulatives listed by grade/developmental levels. Students get to enter data, and the chart in front of them moves around as the data changes. Abstract concepts are often hard to visualize; there is no doubt about that. Those concepts become less abstract and more concrete with these tools because they are right there in front of you – picture-perfect.

Making tasks easier
Most schools now issue Chromebooks or tablets instead of costly and weighty textbooks. All subjects, worksheets, and assignments are on a little device weighing less than two or three pounds, which they can easily take with them, no matter where they go. Students can no longer use the excuse “I forgot my assignment in my desk” or “I left my homework at home” because they upload each assignment to the Cloud as it is completed. All they need to do is log into their student account, pick up the assignment, and tab to the appropriate file. The only excuse is that they left their computer at home, and obviously, that would leave them without social media at lunch if the school provides internet access.

1. a – Liver, b – Gall bladder, c – Pancreas 

2. If the pancreas is totally removed from a person, he will die in a short period. Even if pancreas is only partially removed it will collapse the digestive process. In addition to this, the body cannot regulate the glucose level in blood. 

The digestive juice secreted by pancreas contains three enzymes trypsin, amylase and lipase. Thus if pancreas is removed, the production of digestive enzyme will collapse.

Microwave signals can travel only in straight line. It cannot bend when the obstacles in between. There fore it uses tall towers instead of short one. The dish like antenna mounted on the top of the tower. Hence the two antennas must be in a straight line, able to look at each other without any obstacle in between.
