Hy Freinds !! I am back again on new topic  WannaCry Cyber attack recently infected many of thousands of computers worldwide. WannaCry, also known as WannaCrypt. It is ransomware, which holds a computer hostage until the user pays a certain amount of money to the hacker. So, this becomes an important cyber security issue. The Pew Research Center recently quizzed over 1,000 American adults about cyber security issues. Only 1% of those surveyed understood every issue and answered each question correctly. Less than half of the people given the quiz were able to answer even six of the 13 questions correctly. Topics covered in the quiz included identifying two-factor authentication to knowing the definition of ransomware. These might sound like complex terms only known to computer experts, but ignoring them is playing with fire. People can start to protect themselves by learning and establishing safe practices around these fundamental concepts of cybersecurity: Ransomware Ra...

A Cyberattack is an attack on human someone life as mentally or physically using cyber(Computer) as a way by nation-states, Individuals, groups or organization that target computer information system, Computer networks or any personal computer devices. This Cyberattack increase cybercrime and CYBERTERRORISM who use of computer network tools to shut down national infrastructures like Energy, Transportation, and govt. operations. WAYS OF ATTACK Virus - A virus is a self-replicating program that can attach itself to another program or file in order to reproduce. Worms -A worm does not need another file or program to copy itself.It is a self-sustaining running program which replicates over a network using protocols. Trojan Horse -A Trojan horse is designed to perform legitimate tasks but it also performs the unknown and unwanted activity.  PROTECTION FROM CYBERATTACK Keep your personal information private, Password must change routinely Use ident...

Effect of Temperature on the Performance of Computer Hi Friends, As we all know about the season of summer, it’s too hot, If the human will suffer from heat than obvious our electronic device like Computers will also suffer from the heat. Computers placed in a specific environment to work efficiently in heat, cold, dust and excessive humidity, which decrease the performance of a computer. There is also an External and internal temperature which causes fluctuations on performance.The computer is more vulnerable to heat than to cold. Factor Effecting Electronic device Overheating Many Laptop and PC are vulnerable to overheating. Electronic components run on specific current induced by a low voltage. The sensitive components mean that even a small fluctuation in voltage is dangerous. Overheat decreases the electrical resistance of the electronic component, therefore increasing the current. The slowdown is a result of overheating. PC can shut down when overhe...
