1. Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.
3. Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disiease, and cancer are more likely to develop serious illness.
5. The best way to prevent and slow down transmission is be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face.
7. The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).
9. At this time, there are no specific vaccines or treatments for COVID-19. However, there are many ongoing clinical trials evaluating potential treatments. WHO will continue to provide updated information as soon as clinical findings become available
10. Viruses are microscopic parasites, generally much smaller than bacteria. They lack the capacity to thrive and reproduce outside of a host body.
12. Predominantly, viruses have a reputation for being the cause of contagion. Widespread events of disease and death have no doubt bolstered such a reputation. The 2014 outbreak of Ebola in West Africa, and the 2009 H1N1/swine flu pandemic (a widespread global outbreak) likely come to mind. While such viruses certainly are wily foes for scientists and medical professionals, others of their ilk have been instrumental as research tools; furthering the understanding of basic cellular processes such as the mechanics of protein synthesis, and of viruses themselves.
13. WhatsApp is a text and voice messaging app that launched in 2009. It’s become incredibly popular since then, in no small thanks to its features and flexibility. As a free service, WhatsApp allows for messages and calls on both desktop and mobile devices.
16. Part of what makes this app appealing is that it works on various phone and computer operating systems, helping with messaging. It can also take advantage of Wi-Fi and cellular data to make one-on-one or group calls.
18. Here’s everything you need to know about Whatsapp.
19. Secondary memory refers to storage devices, such as hard drives and solid state drives. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs.
21. Unlike primary memory, secondary memory is not accessed directly by the CPU. Instead, data accessed from secondary memory is first loaded into RAM and is then sent to the processor. The RAM plays an important intermediate role, since it provides much faster data access speeds than secondary memory. By loading software programs and files into primary memory, computers can process data much more quickly.
23. While secondary memory is much slower than primary memory, it typically offers far greater storage capacity. For example, a computer may have a one terabyte hard drive, but only 16 gigabytes of RAM. That means the computer has roughly 64 times more secondary memory than primary memory. Additionally, secondary memory is non-volatile, meaning it retains its data with or without electrical power. RAM, on the other hand, is erased when a computer is shut down or restarted. Therefore, secondary memory is used to store "permanent data," such as the operating system, applications, and user files.
25. NOTE: Secondary memory may also be called "secondary storage." However, this term is a bit more ambiguous, since internal storage devices are sometimes called "primary storage devices" as well
28. In classical and medieval times secondary education was provided by the church for the sons of nobility and to boys preparing for universities and the priesthood. As trade required navigational and scientific skills the church reluctantly expanded the curriculum and widened the intake. With the Reformation the state wrestled the control of learning from the church, and with Comenius and John Locke education changed from being repetition of Latin text to building up knowledge in the child. Education was for the few. Up to the middle of the 19th century, secondary schools were organised to satisfy the needs of different social classes with the labouring classes getting 4 years, the merchant class 5 years and the elite getting 7 years. The rights to a secondary education were codified after 1945, and countries are still working to achieve the goal of mandatory and free secondary education for all youth under 19.
