yes
A computer system is a system of one or more computers and associated software with common storage
A USB Flash Drive is a very common storage type, used by most people with data that needs to be transferred between computers but is too large to email/send via other methods e.t.c.
No a computer is not a magnet. Most of the materials computers are made from (e.g. epoxy fiberglass circuit boards, copper, aluminum, various plastics, silicon, gold) cannot be magnetised. While certain structural parts of a computer are often made from steel, which can be magnetized they are not intentionally magnets. Old computers (from the early 1950s to the early 1970s) used magnetic ferrite core memory as their main RAM and sometimes also as CPU register memory, but this has been replaced with solid state DRAM. Computers have long used magnetic tape for offline data storage. Since the late 1950s when IBM introduced the 350 RAMAC magnetic hard disk it has been common for computers to store data as tiny magnetic dots on spinning aluminum disks. Since 1970 when IBM introduced the floppy disk it has been common for computers to store data as tiny magnetic dots on spinning plastic disks inside a protective sleeve. However both of these are now being replaced by "solid state disks" based on Flash storage (a type of EEPROM - electronically erasable programmable read only memory). So, even though computers have used some parts that operate using magnetism those parts are being phased out. But the computer itself is not and never was a magnet.
Yes, they do. Some people use older computers that need it installed though.
MAGNETIC Storage Media are the Hard disk drivestypesthat make use ofMAGNETIC PLATTER and Read\Write Sensor (Read - Sensing Polarity, Write - Altering theinclinationi.e. sensor attracted or repelled)over the microscopic area on the Platter) for storing Digital Information in form of Binary Signals.
No, not all computers come with DVD burners built into them. Although they are more common in computers today, they are sometimes an upgrade that must be purchased with a computer.
Disk storage devices are most commonly used in personal computers as a means to enhance memory. The most common are hard disk drives, optical disk drives, and even zip drives.
Disk: In a general sense, "disk" refers to any flat, circular storage medium that stores data magnetically or optically. This includes various types of storage devices. Disks can be made from various materials and come in different sizes, with varying capacities. Common examples include hard disk drives (HDDs), solid-state drives (SSDs), optical discs (such as CDs and DVDs), and even floppy disks. Disks are typically used for long-term data storage and retrieval in computers and other electronic devices. Floppy Disk (or Floppy Diskette): A floppy disk, also known as a floppy diskette or simply a "floppy," specifically refers to a type of magnetic storage disk that was widely used in the past, primarily in the late 20th century. Floppy disks are typically 3.5 inches or 5.25 inches in size and consist of a thin, flexible plastic disk with a magnetic coating enclosed in a protective shell. Floppy disks were used for storing relatively small amounts of data, usually ranging from 1.44 MB for 3.5-inch floppies to earlier versions that stored even less data. They were commonly used to distribute software, save documents, and transfer small files between computers before more modern storage solutions like USB flash drives and optical discs became prevalent. In summary, a "disk" is a general term that encompasses various types of data storage media, while a "floppy disk" specifically refers to a now-obsolete type of magnetic storage disk that was common in the past. Floppy disks have largely been replaced by more modern and higher-capacity storage solutions, and they are no longer commonly used in modern computing.
Between a Router and a computer they have CPU'S, RAM, ROM, and an Operating System. Those are the only things that a Router and a Computer have in common.
Most modern computers do not have any floppy drives at all. Ones made before 2001 generally had one. Two floppy drives was common only in very old computers with no fixed storage device.
Magnetite is generally the most common magnetic mineral out there.
Floppy disks do not support migration, due to lack of sufficient memory capacity
