Who discovered floppy disc?
Nobody discovered the floppy disk. Alan Field Shugart working at IBM on the System/370 project invented them in 1970 as a means of storing microcode for loading into writable control store during µIPL (microcode initial program load). Shugart's original floppy, as used on the System/370, was an 8 inch single sided disk with a capacity of 80,000 bytes. The System/370 treated them as read only disks. They were not intended to have a long usage life as they would only be in the drive for a few minutes a day for µIPL and then be returned to the storage sleeve.
Who invented floppy for IBM?
It was a team effort (no single person). This was an 8 inch diameter floppy without a jacket used to store the microprogram code for various models of the IBM System 370 computer (1971) and had a capacity of only 80KB. It was decided that these floppies did not have to be robust (and were practically considered disposable) as they would rarely be used more than once or twice a day when the computer was first powered on and would be stored away safely the rest of the time.Later when floppies became a common data storage medium on small computers, the floppy had to be made much more robust and reliable and the capacity had to be increased. To improve robustness and reliability the 8 inch floppy was packaged in a stiff jacket with a fabric liner that would clean off and capture dust from the floppy surface. Higher recording density was used. The original FM coding used to read and write data was replaced with MFM coding to double the capacity and some drives could access both sides doubling the capacity again (the highest capacity double sided 8 inch diameter floppy could store 1MB).
What do ports 135 and 137 information tell an attacker?
Ports 135 and ports 137 tell an attacker that the user has a Windows OS system. These ports are used by hackers.
What is the file name extension used for Access?
.dbs
Why was the first computer virus made?
The very first virus for the PC was developed as a harmless programme which would simply detect whether or not there was enough space on the floppy disk to carry it. Dubbed 'Brain' because it relabelled disks and changed the volume label of the disk to read "©Brain" (after the company where it was created), it was merely written to explore security holes in the operating system of the software being used by the developers. The virus was written by the Farooq Alvi brothers, in Pakistan. Some sources will incorrectly state that the virus was made to deter piracy of the developers' software, but that was never the intention.
6 Which file system is used by floppy disks?
Any file system can be used by a floppy disk, as long as the minimum partition size of the file system does not exceed the capacity of the floppy. FAT12 is the most common on Windows / MS-DOS computers. AFS was common on earlier Macs. ext was used among many Linux users. Floppy disks can use a variety of file systems. On MS-DOS and Windows computers, the primary file system for floppies is FAT12. On older Macs, the file system was HFS or MFS. Linux computers sometimes use ext.
What file system used by floppy?
Under Windows, a floppy drive is always formatted using the FAT 12 file system.
What a floppy drive is used for in a computer?
for putting floppy disks in it
What operating system is used on bootable CD's or floppy disks?
Warcraft DOTA system and Counter Strike version 1.3 System
What were used before floppy disks?
Cassette tapes.
Why do you need to be careful when sharing floppy disks with friends?
we have to be careful when sharing floppy disks with friends because as you know floppy disks are used for transferring small files between computers it might lead copy of small files and spread of viruses.
Can i use a floppy disk in a zip drive?
No. Zip drives cannot read floppy disks, and cannot be used on a traditional floppy controller.
What are the difference between FAT and NTFS-use-in-table?
If your wondering which file system is beter, use NTFS, a FAT/FAT12/FAT16/FAT32 files system is usually used for removable drives, like Floppy Disks, Flash Drives, Jump Drives, or CD's, NTFS is typically used for hard drives as it has a much larger file size limit.
Is floppy disk non-volatile storage?
yes, this days floppy disks rarely found but they were commonly used because they were non - volatile
How is a floppy disk useful?
Since higher storage and media devices have been released such as USB's and CD's, floppy disks have become outdated due to the maximum capacity that is now available to computers. In the 1990's floppy disks were very popular and widely used.
What did people use before floppy disks?
Before Floppy disks were available, people still transferred data. It used to be with help of punch cards, reel to reel tapes, and cassette tapes. The early home computers used cassette tapes.
What uses magnetic particles to store items on a disks surface?
Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
