Media storage (Storage).
Media used to store data in the past from the hole on the card is used magnetic tapes that can read and write more quickly. As well as easy storage and has the capacity to develop disk (Disk) up. Which can be read And find information more quickly than the magnetic tape disks currently have two types.
1. Disc is a disc with a soft manner and a thin plastic sheet containing the external magnetic coating. Sample discs such as disc size is 3.25 inches. We use the same.
2. Hard disk as the disk is aluminum sheet containing the magnetic coating. Such as hard disk types. This disc recordable discs than light, because they can be densely packed information than . And the rotational speed very quickly. So this disc is an excellent collection box will be the cover disc. Not the weather. Handy Drive Or dust is present in the disc at all and also come equipped with a newly developed, called Handy Drive is a small chip that can store data within the ROM is similar to the writing. Mb It will connect with computer through USB port currently range from size 2, 4, 8, ... up to 128 Mb.
Disk
As mentioned above, the second disc is a disc with a certain style. For the structure of the disc is in the third.
1. 1. Track is the manner in which the disk is divided into many bands band.Each band called tracks. 0 It starts at track 0.
2. 2. Sector is divided into tracks again if the other will look at these disk is divided into sections by using the diameter In the young disc will be divided into sectors out from 8 to 32 sectors. Sheet, as the hard disk, but may be divided into several hundred sectors also. It starts at sector 0, but due to the width of the sector in the periphery is larger than the inside sometimes be divided into sectors on the outer again to the appropriate size.
3. 3. North cylinder because hard disk is the disk stack several sheets together, we will run the track and sector of the disk that matches each of the cylinder
The smallest unit in the structure of the disk block (Block) or from the field share the track and sector This blog may be an area of 512 bytes or 1024 bytes, but also by how to manage disk .
For the present it has the option to work on the computer. The sample was stored information that will be proposed as follows.
Hard disk
(Hard Disk) is used for storage of various computer look like a rectangle with outer shell and metal strength and circuit for controlling the working faces at the bottom with a connector cable and cord culture. Internal components are completely sealed off by the disc and the heads more sensitive. And will not withstand the impact of that suspension should be very careful. Time to hold should not shock or vibrate Hand and being careful not to other devices on the motherboard usually hard usually contained in the box provided only a local will be connected. Signal to the hard disk controller. Culture and power cord from the power supply always here .Known to encourage the various hard enough as an initial basis for getting to know and choose to use each.
CD-ROM.
The CD-ROM is divided into tracks and sectors like the disc, but sectors of the CD-ROM will be the same size all sectors make to keep more data on the drive CD-ROM running motor will start moving with speed multiple values in order to speed in reading data from CD-ROM still consistent all sectors such as sectors. Around outside of it Rue inside any laser will shoot a CD-ROM. The beam is moving the focus lens position by operation of the coil. Laser beam will be surpassed over the CD-ROM and is reflected back to the surface of the CD-ROM will be bumpy section of the hole to run,"Land" for areas where there is no depth to call "Peace " skin. We use this format instead of the data in the form of 1 and 0 when the light is scattered pin also will not reflect light, but the lens will be reflected through the prism bar. Then refracted through the prismatic light to the sensor again affecting all the beams of light to detect the source voltage. Or the 1 and 0 that the computer can understand. The data for the CD-ROM also requires a laser with a laser beam from the recording head of the machine. Record second impact surface of the plate if the second impact is what makes the holes smaller. Area will not be saved looks basically flat so on alternately throughout the disc.
Drive CD-R RW
Drive CD-RW CD recorders can read and write data on the CD (the CD used. CD-R CD-RW) Available through CD-R and CD-RW) section Software that are used in recording recordable CD drive Easy CD Creator, Nero Burning ROM CR-R CD Audio Typically, if we buy the recordable CD drive will come with free software such as Easy CD Creator, Nero Burning ROM, etc. and you know that we can bring CR-R disc to make the CD Audio disc with
Recording speed measurement unit used to measure the speed of the CD. Speed read the 150 Kb / sec (CD-Rom drive speed of the first generation) under the symbol characters 'X' suffix to indicate amount of speed (should be purchased at least 20X speed up).
Floppy Drive
Is used to read and Floppy Burn Floppy. Disk Disk capacity that difference as 360KB, 720KB, 1.2MB, 1.44MB, 2.88 MB 360KB, 720KB, 1.2MB, 1.44MB, 2.88 MB. Which is 3.5 "and 5.25" Floppy Drive and also to have Zip Drive, Jazz Drive, SuperDrive Trump Other temporary storage device such as Zip Drive, Jazz Drive, SuperDrive, and Trump. Drive Port Drive that can be connected to the Port. USB to exchange data quickly ... the end .....
