The triumph of the internet is all around today. Nowadays, people can do almost everything from sitting at home, such as shopping to getting married! In a word, if there is the internet, everything is in one's hands. In this era of speedy internet and communication technology, there are still some places in the world where the internet is far away, and even the mobile signals do not reach properly. However, it is not like those places are deprived, or no one gives attention to them. The places that don't have internet are mainly due to geographical location or natural reasons. Some villages in Congo, Africa, are such remote locations. But this time, Google's new project named 'Project Taara' is working on providing high-speed internet to those remote villages. Read: Mobile internet speed increases only by 15 percent in Bangladesh, one-fourth of global average What is Project Taara? According to Project X, Google's own company, the technology will actually transmit the internet at very high and invisible super high-speed laser-based system light. The subject is a lot like optical fiber, but in this case, no cable or wire will be used. This innovative approach to Internet connection was implemented under Alphabet X's 'Project Taara.' Alphabet X is a research and innovation company under Alphabet Inc., the parent company of search giant Google. The company works with a variety of innovative technologies, in many cases with strict confidentiality. Read: Virtual RAM: Types, Advantages, Disadvantages of Virtual Memory It has already successfully set up a laser-based system to supply the internet across the Congo River at 20 GBPS speed, which can cover distances of up to 20 kilometers. When did Project Taara start? Project Taara has been working for three years since 2017. Alphabet X is partnering with Econet Group and Liquid Telecom to launch high-speed Internet services in sub-Saharan Africa and has even begun commercial marketing in Kenya. How does Taara service work? This technology usually sends a signal to the receiver via radio wave from a server with a transmitter mounted on a tall building or a tower. The company claims that currently, people are able to access the internet at speeds of up to 1 Gbps only. But the new technology will allow users to access the Internet at speeds of up to 20 GBPS.  Read: AI critical enabler of energy transition: WEF While the current broadband fiber-optics service transmits information on pulses of light, the Taara will transmit the data in a special form of twisted light. The regular fiber-optics' encoding and processing system affect the data speed. But the twisted light forms the missing key and helps in unlocking the super-fast communication. The advanced Taara communication system not only carries more data; but also processes it faster through the light beams. Nevertheless, the internet speed can be as much as 100 times faster than the current system broadband system.  Has this been tested? Google's technology has already been tested in remote areas of India and Africa. This new technology will greatly reduce the difficulties of providing internet service in the towers, and tall buildings.  Read 5G Smartphone: What are the benefits of 5G? Who needs a 5G Phone? Besides these, by virtue of the new technology internet access can be assured in jungles, rivers, railway tracks, and several other remote areas. In simple words, the advanced technology is expected to be very effective in places where it is virtually impossible to deliver optical fiber. The technology has already been successfully tested in Andhra Pradesh, India, and villages across the Congo River, Africa. And it has yielded promising results in each case. Previously Google took another step named “Project Loon” to provide internet service through the balloon, which did not make the cut. Google's Taara, on the other hand, seems very promising as it transmitted 700 TB data over a 20-day period test in Congo. Furthermore, the light beam technology had 99.9 percent during the testing period. Read E-Waste Crisis: Effects of Electronic Waste on Environment and Human Health On the user's side, there was no hint when the data passed through FCOS nodes or the wires. Further, Google wanted to make the experience indistinguishable, and seemingly they are successful. According to Google, the system is placed high up, and it can adjust itself up to five degrees to uphold a perfect connection. The test also shows that the laser system was up even in the face of unexpected obstacles, such as extreme weather, flocks of flying birds, etc. The latest test removed the pretty stubborn connection gap between the Republic of Congo city of Brazzaville and the Democratic Republic of Congo city of Kinshasa. Although the names are almost the same, the Republic of the Congo and the Democratic Republic of the Congo are two different countries. The two countries gained independence from the European colonial occupation in 1960 at about the same time. Read Internet Safety Tips for Children, Teens, and Adults The distance between Brazzaville and Kinshasa was five kilometers only. But, it was complicated and expensive to connect the two cities with fiber cable in a conventional way due to the river flowing between them. The cost of broadband connectivity has increased fivefold as the Internet has simply turned the tide. The problem is partially solved by Alphabet X's Lighting Internet connection or The Wireless Optical Communication (WOC) system. Therefore, the 17 million people living in those cities will be able to access the high-speed internet soon. Challenges The WOC system comes from 'free space optical communication' technology. The technology originated from Project Loon, a project to send data using lasers between multiple balloons floating in the atmosphere. Read: Microsoft fixes cloud platform vulnerability after warning However, Alphabet closed Project Loon in February 2021 due to a lack of commercial potential. Now they started Project Taara with the same concept. But this technology is not perfect yet. The system was up 99% during the taste. But, unwanted objects like fog, hostile weather, clouds, or birds flying through the light waves, can disrupt the WOC system. However, the BBC reports that it is possible to deal with that complication by increasing the power of the laser transmission. The WOC system works much like a telescope; Mirrors, lighting, software, and hardware - these four combine to control the destination of light. The report says that the researchers have also found a way to avoid the disruption of the connection due to the birds flying through the middle. Alphabet X is also testing the technology in Kenya, India, Mexico, and the United States. Read Harnessing assistive technology for Persons with Disabilities in South Asia

Virtual memory functions as extra memory, providing system support like additional RAM. Virtually memory swaps non-essential data to a temporary file in the hard disc or permanent storage. It can call the data later when necessary. Virtual memory can be super handy when a device or processor needs a memory boost. It’s also less costly than the actual RAM. However, such memories are not without disadvantages. One must be aware of the pros and cons of virtual memory to avoid unexpected consequences. Types of Virtual Memory/ RAM? The first step of knowing about virtual memories is to learn their classification. Computers handle virtual memory either through paging or segmentation. So, the type of virtual memory depends on how it’s being handled. Below is a bigger picture about them: Paging This kind of virtual memory operates by partitioning memory into parts known as paging files. When RAM is full, it moves any unused pages to the specific part of a hard drive designated for virtual memory. This procedure is executed by the computer utilizing a swap file. A swap file is a predefined area on the hard drive for expanding the virtual memory of the RAM. Moving unnecessary data to the hard drive makes some free RAM space for necessary activities and guarantees that the system never runs out of actual memory. Read Why Do Mobile Phones Explode? How to Protect Your Smartphone from Blasting? The computer utilizes page tables to convert virtual addresses into physical addresses. This is done as only a part of the instruction processing system by the Memory Management Unit of the computer. Segmenting Another technique of controlling virtual memory is called ‘segmenting’. This process splits virtual memory into segments of different lengths and transfers unused segments from the virtual memory of the computer to the hard drive. Segment tables, like page tables, keep track of whether a segment is stored in the memory or as a physical address. The difference between segmenting and paging is that segmenting parts memory into different lengths, while paging divides memory into equal-sized pieces. In paging, the computer's hardware decides section size, while in segmentation, the user may choose segment length. Read:E-Waste Crisis: Effects of Electronic Waste on Environment and Human Health Benefits of Virtual Memory/ RAM? Having a virtual memory can be of real advantage for the users, especially in critical situations. Here are some of the best advantages that come with virtual memory.  Segmented Speed Rise Virtual memory doesn't bother using the whole RAM to gain a certain level of speed. Instead, it assists a particular segment of the whole program to gain an expected speed. It uses the segment only when the segment of the program needs to execute a necessary instruction or run another program. Multi-programming Environment If users need to make a multi-programming environment, they should use a virtual memory system. Such memory provides the extra support that smoothens the multi-programming environment. Furthermore, virtual memory helps users do large programs into comparatively smaller programs. There is no specific multi-programming limit. Read Ai and Future of Content Writing: Will Artificial Intelligence replace writers? Memory Share Programmers and designers often need systems that can share data or information between memory. They will find a virtual memory system quite helpful. The process can communicate data and instructions via and between memory. Data Placement Another big perk with virtual memory is users can place their data and codes anywhere in the physical memory without a relocation. These data or codes can be read anytime from the disc. Users will find the process larger than other physical memories. Users will get more space for virtual addresses compared to physical memory. Checks External Fragmentation When unused memory is split into smaller segments and interleaved with assigned memory, this is known as external fragmentation. It is considered an issue as an algorithm for storage allocation, especially when these algorithms fail to effectively arrange memory utilized by applications. Read: Mechanical Keyboard Buying Guide with the Price Range in Bangladesh No Memory Holes Memory holes may cause unusual fragmentation. However, virtual memory overcomes this problem since it does not contact the physical memory management unit. Furthermore, each program has its individual mapping, and users can utilize the mapping to place their program data anywhere they want in the RAM. Security Each program has the ability to access any 32bit memory address. The issue arises when two programs use the same address in address space to keep their results. In that case, the output of one program may be altered by another, resulting in users not receiving the desired outcome. It is the most serious issue that virtual memory can address. Disadvantages of Virtual Memory/ RAM? It might sound a bit queer, but virtual memory has some disadvantages on its side. Before having a system that supports virtual memory, users should know about all these disadvantages. Thus, they will know how much to expect and also the limitations. - If the system is utilizing virtual memory, applications can run and execute slower. Because virtual memory executes things. Read Ai and Future of Content Writing: Will Artificial Intelligence replace writers? - Switching between apps will most likely take a longer time. - Virtual memory reduces the amount of hard disk space available for your usage. - It has a negative impact on system stability. - It enables bigger programs to operate on systems that do not have enough physical RAM to execute them on their own. - It can't provide support at the level a RAM does. Read Mobile Phone Network Booster Buyer Guide, Price Range in Bangladesh - It has a detrimental impact on a system's overall performance. - It occupies the storage space, which might otherwise be utilized for long-term data storage. Conclusion Virtual memory is an inexpensive way to extend the RAM capacity of a system. It can be an effective alternative to purchasing new RAM. However, Virtual RAM has both advantages and disadvantages for a user. That's why users should figure out why they need a virtual memory in the first place. Then they should estimate whether it will provide what he wants. Without estimating these aspects, using a virtual memory system can hamper their work.
