Answer:
There you go. Hope it helps. Please mark as brainliest and sorry 4 the late answer. There were a lot of questions that had to be briefed.
Explanation:
1.Memory is internal storage areas in the computer system. The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks.
There are several different types of memory:
RAM (random-access memory): This is the same as main memory. When used by itself, the term RAM refers to read and write memory; that is, you can both write data into RAM and read data from RAM. This is in contrast to ROM, which permits you only to read data. Most RAM is volatile, which means that it requires a steady flow of electricity to maintain its contents. As soon as the power is turned off, whatever data was in RAM is lost.
ROM (read-only memory): Computers almost always contain a small amount of read-only memory that holds instructions for starting up the computer. Unlike RAM, ROM cannot be written to.
(PROM, EPROM, EEPROM, EEPROM...not includingthem because you might not have studied these in class 7.)
2.A removable storage drive is used for storing and transporting data from one computer to another. It will allow you to read (open), write (make changes and save), copy, add, and delete files. It can also be called external storage devices.
eg: USB, CD, DVD etc.
3. 5 storage devices:
Hard Disk
A magnetic disk on which you can store computer data. The term hard is used to distinguish it from a soft, or floppy, disk. Hard disks hold more data and are faster than floppy disks
CD
>Compact disc (CD) is a digital optical disc or a small optical disk usually containing recorded music or computer data also : the content (such as music or a computer program) of a CD released as a unit promoting her latest CD it was co-developed by Philips and Sony and released in 1982
>A normal CD can have upto 700MB
DVD
>DVD Stands for "Digital Versatile Disc." A DVD is a type of optical media used for storing digital data. A standard video DVD can store 4.7 GB of data, which is enough to hold over 2 hours of video in 720p resolution, DVDs are also used to distribute software programs.
>invented and developed in 1995 and released in late 1996.
USB
A Universal Serial Bus (USB) is a common interface that enables communication between devices and a host controller such as a personal computer (PC) or smartphone. It connects peripheral devices such as digital cameras, mice, keyboards, printers, scanners, media devices, external hard drives and flash drives.
RAM
RAM is short for “random access memory” and while it might sound mysterious, RAM is one of the most fundamental elements of computing. RAM is the super-fast and temporary data storage space that a computer needs to access right now or in the next few moments.
4. DVD drives are not only able to play and write to DVD media, but also CDs. The main difference between CDs and DVDs is the size of available storage. With a CD, you'll get around 700MB at the most. A DVD, on the other hand, will be able to hold just shy of 5GB (4.7GB) worth of data.
DVD-audio has the potential to replace CDs because of the higher quality of the sound.
Therefore DVDs are more preferable.
