the right place on the hard disk has to be found, then the read/write head must be placed there, then the sector (a small part of the hard disk) is read or written, if it's read, the data is moved into the memory, maybe by the DMA (Direct Memory Access) Controller. Is it's a write operation, the data must first be given to the Hard Disc Controller.

No not really, it's the brain.

CPU is the Central processing Unit which receives input via input devices like keyboard, mouse , scanner, mic etc. It's main job is to process the input and send to the relevant o/p device.

It controls the flow and process of instructions, in time with a clock pulse.

It needs to handle both input and output of binary data.

The last generation of floppy disks were 3.5 inches in diameter. They were capable of holding 1.44 megabytes of data. By comparison, a Compact Disk holds about 650 megabytes.

Usually an arrow pointing to it, or a number 1 on the connector. It's also on the side with the red wire. And most boards are keyed with a slot on the side of the female part, and extrusion on the male connector... so it can only be inserted the proper way.

Around 35 to 40 years.

If you have a CD Burner such as Nero or Roxio (Sonic solutions), start the program, choose Data CD and then then choose from the task bar "Add Data" and then select the drive where your data is, and follow the instructions.

The very first CD player was invented by James T. Rusell. James T. Russell, a senior scientist at the Pacific Northwest Laboratory, invented the technology for the compact disc in 1965. By 1985, Russell had earned 26 patents for various innovations with CD-ROM technology.

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.

Unplug the power cord

You would have to search online for an external floppy disk drive or buy an old PC that has one. In the "old days" every computer had a built-in floppy drive. It would always be right in the front. About a 4" wide slot.

Bigger storage space, smaller chance of files getting corrupt or hardware getting damaged

Most floppy disks will come pre-formatted. All floppy disks need to be formatted to be usable.

There are many disadvantages of magnetic tape.

1. Mag tape is in physical contact with the recording heads, causing friction and wear.

2. Magnetic tape is an analog medium, even when digital data is being stored.

3. Tape can stretch or break, or lose its magnetic data due to age, heat or the Earth's magnetic field.

A hard disk (HD for short) and floppy disk (FD for short) both work in the same manner, except that on can hold more information. Both are a type of magnetic media which can have information written and erased many many times. A lot better than paper when you write something and erase many times, that paper gets thin, then GAME OVER! I am including a link to better explain this from "howstuffworks". I really love that site. I could spend all day on there reading about anything! About their differences. the most common floppy disks only hold about 3.14MB of data. Where an electric HD can hold almost any amount up to several terabytes today!! That is huge. The FD uses a mechanical motor to move the read/write armature that hovers over the FD material (most comparable to cassette tape material). This is where it changes the magnetic properties of the tape material, and bingo, last night's report is saved! The HD works in a similar fashion. HD's have dense metallic disks inside that can spin at thousands of RPM's (rounds per minute). As the disks spin a similar Armature that is is surrounded by some really powerful magnets changes the magnetic properties of the dense metallic disks and Bingo, last night's report, music, and the whole operating system is spinning virtually forever. That is the basics. Hopefully that sums things up in a nutshell. Visit that site at howstuffworks to really see a more in depth look at floppy disks & hard drives!

A CD-ROM ( Compact Disc- Read Only Memory ) is an Optical Type of Device. The reason of it being optical lies in the fact that its read/write head is optical in nature ( It uses a red colored light).

Low capacity; only 1.4 MB.

Slow data transfer speed

Can not use long time,

ie. they become corrupt unexpectedly.

Most new computers do not have a floppy drive.

Zip disks can hold 100 megabytes. Today's hard drives usually hold 250 gigabytes, smaller ones are around 100 gigabytes, and large ones are upwards of 500 gigabytes. One gigabyte is 1000 megabytes, so the typical hard drive can hold 2,500 times more than a zip disk.

To answer the question in one word, no.

hard

Yes, a floppy disk will be affected by a magnet. Many floppy disks have magnetic components so coming into contact with permanent magnets can damage them.

i don't know thats why i am asking you?
