Here are 30 Kickass and Interesting Facts About Computers. Networks of such machines are often referred to as botnets and are very commonly used for a range of malicious purposes, including sending spam or performing DoS attacks. Worms can often go unnoticed until their uncontrolled replication process consumes system resources, halting or slowing the infected computer. With the standard QWERTY keyboard, the longest word one can write is “Typewriter”. When a machine starts sending out too many scans, it is a sign that it has been infected, allowing administrators to take it off line and check it for malware. File-Sharing Worms. It often uses a computer network to spread itself, relying on security failures on the target computer to access it. If user interaction is required for the malware to spread, it is called a Trojan horse. Viruses then spread to other disk drives and machines when the infected files are received in downloads from websites, email attachments, shared drives or when carried in files on physical media, such as USB drives or—in the early days—floppy disks. Douglas Engelbart introduced the first computer mouse to the world. Unlike a computer virus, this is done without changing files on a computer, and without affecting the boot sector of media.
