A virus program has to be run before it can infect your computer. Viruses have ways of making sure that this happens. They can attach-themselves to other program or hide in code that is run automatically when you open certain types of files. Sometimes they can exploit security flaws in your computer’s operating system to run and to spread themselves automatically You might receive an infected file in a email attachment, in a download from the internet, or on a disk. As soon as the file is launched, the virus code runs. Then the virus can copy itself to other file or disk and make changes on your computer. 1.)

Floppy Disk 🖪 (Hi friends... today I 'am going to explain about the History of the floppy disk and Types of the floppy disks...So read the post and renew your knowledge about the history of FLOPPY DISK.) Alternatively referred to as a floppy or floppy disk, a floppy diskette is a storage medium capable of holding electronic data, like a computer file. The floppy disk was created in 1967 by IBM as an alternative to buying hard drives , which were extremely expensive at the time. Use of Floppy Disk Early computers did not have CD-ROM drivers or USB; floppy disks were the only way to install a new program on a computer or back up your information. If the program was small(less than 1.44MB for the 3.5" floppy disk), it could be installed from one floppy disk. However, because most programs were larger than 1.44MB, diskettes were usually required. For example, the diskette version of Windows 95 came on 13 DMF diskettes and was installed one disk at a time. Floppy disks were also

The History of the Wheel The wheel has been an essential part of human life from the very earlier years of human civilization. The wheel can be best described as a circular object that rotates on an axial bearing. The earliest wheel was known to be wooden disks with a hole in the middle for the axle. The word “Wheel” first came from an Old English word. In Sanskrit, the wheel is called “Chakra” to mean round or circle. It is believed that the wheel first originated around 3500BC in Mesopotamia (part of modern – day Iraq) where it was use for chariots. Some argue that it was invented by the Mesopotamians, the Northern Caucasus and Central Europeans. Therefore, the issue of the where the wheel originated in still remains a mystery. The next step of the evolution of the wheel was made by the Egyptians 1500 years later in 2000BC when they used spokes in their wheels and proudly used them in their chariots while the Greeks have the honour of introducing the cross bar or H-type wheel.
