If it is said, let us know what is the secondary memory of computer - What is a Secondary Memory in English
What is Secondary Memory in English-कंप्यूटर की सेकेंडरी मेमोरी क्या होती है ?
Secondary memory is added separately and when it is used for storage, it is also called secondary storage device, its speed is less than primary memory but its storage capacity is more primary memory and it needs to be upgraded (reduced) when needed. Or increase), let us know what type of secondary memory is -
1. Magnetic Tape(चुम्बकीय टेप)
2. Megnetic Disk(चुम्बकीय डिस्क)
3. Optical Disk(ऑप्टिकल डिस्क)
4. USB Flash Drive(यूऍसबी फ्लैश ड्राइव)
1. Magnetic Tape-चुम्बकीय टेप
It looked like the cassette of an old-fashioned tape recorder, in which a layer of magnetic material was mounted on a plastic ribbon, on which the head was used to store the data, just like a tape recorder, this data Of how many times could be written and erased and it was very cheap.
2. Megnetic Disk-चुम्बकीय डिस्क
चुम्बकीय डिस्क (Megnetic Disk) दो प्रकार की होती हैं -
2.1. Floppy Disk(फ्लॉपी डिस्क)
2.2. Hard Disk Drive(हार्ड डिस्क ड्राइव)
2.1 Floppy Disk-फ्लॉपी डिस्क
The floppy disk consists of a round disk of very thin plastic which was closed in a plastic cover, the disk was covered with a layer of magnetic material, floppy disk based on the size and storage and two types of storage. is -
2.1.1 Mini Floppy-मिनी फ्लॉपी
Mini Floppy has a diameter of 3½ inches and has a storage capacity of 1.44 MB. It needs a 3½ inch floppy disk reader to be read into the computer, this is about 360 RPM. That is Revolutions Per Minute means rotation / rotation per minute.
2.1.2Micro Floppy-माइक्रो फ्लॉपी
Micro Floppy has a diameter of 5½ inches and a storage capacity of 2.88 MB, also requires a 5½-inch floppy disk reader.
2.2 Hard Disk Drive-हार्ड डिस्क ड्राइव
Let us tell you that the world's first manufacturer of Hard Disk Drive is IBM, which was made in 1980, it is an aluminum metal disk on which the material is coated, this disk is located on a spindle. Rotates fast and its speed is measured in RPM ie Revolutions Per Minute i.e., round / rotation per minute, Aaj Tak is available on the market with Hard Disk Drive with 5200 RPM and 7200 RPM, Track in Hard disk Drive and
There is a data store in the sector. One sector stores 512 bytes of data, an 80s hard disk drive whose first partition was named "C" drive and today when you install Windows, it is first installed in the "C" drive. If you talk about storage, Hard Disk Drive is used as the main secondary memory. Currently, hard disks ranging from 1 terabyte to 100 terabytes are available.
3. Optical Disk-ऑप्टिकल डिस्क
The optical disk consists of a round disk of polycarbonate, which is coated with a chemical substance. The optical disk data is digitally protected, low-capacity laser light to read and write data to the optical disk. Optical discs are of three types -
CD(सीडी)
DVD(डीवीडी ड्राइव )
Blu Ray(ब्लू रे)
4. USB Flash Drive-यूऍसबी फ्लैश ड्राइव
It is currently the most popular and portable secondary memory device that is connected to a computer via a USB port which we also call as a pen drive, it is used to save data other than video, audio.
