Which optical disk type has the highest storage capacity?
CDs can store up to 700 megabytes (MB) of data and DVDs can store up to 8.4 GB of data. Blu-ray discs, which are the newest type of optical media, can store up to 50 GB of data. This storage capacity is a clear advantage over the floppy disk storage media (a magnetic media), which only has a capacity of 1.44 MB.
Why ROM is called non volatile memory?
RAM is referred to as volatile memory and is lost when the power is turned off whereas ROM in non volatile and the contents are retained even after the power is switched off. RAM is called volatile because it is temporary memory. ROM is called non volatile because it is permanent memory.

Is there anything bigger than a Yottabyte?
As data gets bigger, what comes after a yottabyte? An exabyte of data is created on the Internet each day, which equates to 250 million DVDs worth of information. After a zettabyte comes yottabytes, which big data scientists use to talk about how much government data the NSA or FBI have on people altogther.

Which optical disc has the greatest storage capacity?
Which optical media has the greatest storage capacity? A Blu-ray disc has the greatest storage capacity of optical media. A single-sided Blu-ray disc holds up to 25 GB of data.
What are the three main types of optical storage?
Read-Only Optical Discs
- CD-ROM. Compact Disc – Read-Only Memory (CD-ROM) discs can hold around 800MB of data.
- DVD-ROM. Digital Versatile Disc – Read-Only Memory (DVD-ROM) discs can hold around 4.7GB of data (a dual-layer DVD can hold twice that).
- Blu-Ray. Blu-Ray disks are a recent replacement for DVDs.
Which type of optical disc holds more information a CD or a DVD?
DVD (Digital Versatile Disc) DVDs are the same physical size as CDs but hold much more data – a single sided disc can hold up to 4.7 GB .
Is ROM a volatile memory?
Types of memory that retain their contents when power is turned off. ROM is nonvolatile, whereas RAM is volatile. This term often refers to the CMOS memory in PCs that holds the BIOS.
Is ROM primary memory?
Examples of Primary Storage. ROM: Unlike RAM, Read Only Memory (ROM) is both a non-volatile and permanent form of primary storage. Cache memory: Also known as CPU memory, cache memory stores instructions computer programs frequently call upon during operation for faster access.
How many types of ROM are there?
There are five basic ROM types:
- Flash memory.
What are two types of data storage?
Data Storage Device Types. There are basically two types of data storage devices available. Dynamic storage requires power to maintain the information it stores. An example of this type of storage is random access memory (or RAM).
What is the fastest type of storage in a computer based device?
ANS:-A register is the fastest memory. Register a part of the computer processor which is used to hold a computer instruction, perform mathematical operation as storage address, or any kind of data.
What are examples of storage devices?
Examples of storage devices include:
- Hard disk.
- Magnetic tape.
- Flash memory (USB memory sticks)
What are the 3 types of backups?
Learn which data backup type is best — full, incremental or differential backups, or newer methods, such as synthetic and incremental-forever backups. For quite some time, there have been three basic data backup types: full, incremental and differential.
What are the different types of secondary storage devices?
It must first be copied into primary storage (also known as RAM). Secondary memory devices include magnetic disks like hard drives and floppy disks ; optical disks such as CDs and CDROMs ; and magnetic tapes, which were the first forms of secondary memory.

Who invented the Sage computer?
SAGE. The U.S. military SAGE Computer System, developed in the 1950’s and operational by 1961, is beyond all doubt the largest, heaviest and most expensive computer system ever built! SAGE was the brainchild of Jay Forrester (the creator of the Whirlwind computer) and George Valley, two professors at MIT’s Lincoln Lab.
What are the disadvantages of optical storage?
Optical discs are not vulnerable to data loss due to power failure like volatile memory; not as subject to wear like most non-volatile memory, such as flash; and much more physically sturdy than magnetic tape, which is the leading archival storage medium. The biggest disadvantage of optical storage is disk capacity.
Why CD ROMs are classified as optical storage device?
