What is hard disk and floppy?
These days (2012) you will not find many floppy disks (although just a couple of years ago we had to order special floppy drives for a server because some software would only be installed if it booted from Drive: A a floppy). There were 8 inch and 5 inch and 31/2 inch floppy disks which were common. The latest (diskettes) were the smallest and were protected by a hard plastic casing. Inside a thin Mylar disk coated with a magnetic surface stored the 1.44 Mb that was the capacity of most diskettes. Hard disks have one or more aluminium or glass disks coated with magnetic surfaces. These hold much more information and now (2012) there are units that can store 3Tb or more.
Does a system disk have to be a floppy disk?
No. A "system disk" is simply any disk which the computer can boot from and has an operating system installed on it. In most modern computer systems, the hard disk is normally the system disk. However most systems can also boot from a floppy disk, a cdrom, or even a USB thumb drive, providing of course that the media in question has the necessary system files on it. Many older systems did not have the ability to boot from the cdrom drive or USB drives. On these systems the only options were booting from the hard disk or floppy disk, so if the OS hadnt been installed to the hard disk yet (or it was broken) the only other option was the floppy disk.
How many kilobytes of data can a diskette store?
A standard 3.5-inch floppy diskette can store 1.44 megabytes of data, which is equivalent to 1,440 kilobytes. Older 5.25-inch floppy diskettes had varying capacities, typically 360 kilobytes or 1.2 megabytes. The actual storage can vary based on the formatting and type of diskette used.
How many diskettes are there to one CD ROM?
10
When selecting secondary storage devices for a new desktop PC which is more important a CD-ROM drive or a floppy drive Why?
Floppy drives are not as necessary as they once were because the industry is moving toward storage media that can hold more data, such as CDs.The CD-ROM or optical drive. Floppy disk drives have stagnated in development; any off-the-shelf drive these days will support the highest commonly available capacity, 1.44 MB. Many people these days don't even use floppy disks.
If a motherboard has two IDE channels how many IDE devices can be accomodated?
Each IDE connector on the board supports two channels per. (Two drives) The combination of drives can vary. For instance, hard drive-cdrom, hard drive-hard drive, cdrom-cdrom, ect....ect.
How many floppy disc equal a 4gb flash drive?
You would need 729 floppy disks to hold 1GB of data. This is because:1 gigabyte is equal to 1,073,741,824 bytes1 floppy disk can hold 1,474,560 bytesSo floppy disks per gigabyte is equal to 1,073,741,824 divided by 1,474,560, which is 728.18 disks. This means you would need 729 disks to hold the full 1GB.
How many megabytes can CDROM have?
700Mb. But it depends on the quality sometimes there are cheap cds with 650mb
What is the major limitation of the CDROM as a storage medium for multimedia?
CD's speed, size (amount of data it can hold) and the fact it is W.O.R.M., Write Once, Read Many vs W.M.R.M, Write Many, Read Many (Harddrive for example) are the major drawbacks for the CDRom as multimedia storage.
How many heads are in a floppy drive actuator?
There are two heads on a floppy drive actuator.
How much storage does a diskette have?
A standard 3.5-inch floppy diskette typically has a storage capacity of 1.44 MB. Older 5.25-inch diskettes had capacities of 360 KB or 1.2 MB, depending on the format. These storage limits are quite small by today's standards, as modern storage devices can hold many gigabytes or terabytes of data.
Differences between a floppy disk and a hard disk?
A floppy disk is a flexible and magnetic data storage system that is removable from the computer that can store up to 3 megabytes of data. A hard disk on the other hand is the main place that a computer stores data. It is a rotating disk that uses magnetic patterns to store data. Floppy disks have been replaced by USB flash drives.These days (2012) you will not find many floppy disks (although just a couple of years ago we had to order special floppy drives for a server because some software would only be installed if it booted from Drive: A a floppy). There were 8 inch and 5 inch and 31/2 inch floppy disks which were common. The latest (diskettes) were the smallest and were protected by a hard plastic casing.
