What memory is erased when the computer is turned off?
Flash memory- is a form of non-volatile computer memory that can be electrically erased and reprogrammed. Flash memory is available in 3 forms: 1. Flash memory card (aka RAM cards)- Removable storage media that is indersted into a flash memory port. It retains data when the power is turned off.

Why are SSD so expensive?
Starting at 512GB, SSDs can cost thousands of dollars, too expensive for most of us to afford or justify. On the other hand, traditional hard drives are much more affordable, with 2TB drives costing just around $80. Basically, based on the cost per gigabyte, SSDs are about 5 to 10 times more expensive than hard drives.
What size SSD should I get?
So, while you can live with 128GB in a pinch, we recommend getting at least a 250GB SSD. If you play games or work with a lot of media files, you should consider getting a 500GB or larger storage drive, which could add as much as $400 to the cost of your laptop (compared to a hard drive).
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 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).
How much storage do I need?
A. Most non-professional users will be fine with 250 to 320GBs of storage. For example, 250GB can hold more than 30,000 average size photos or songs. If you’re planning on storing movies, then you definitely want to upgrade to at least 500GB, maybe even 1TB. Granted, this is all for conventional hard drives.
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 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.
- DVD-RAM.
What are the three main types of secondary storage?
There are three main types of secondary storage in a computer system:
- solid state storage devices, such as USB memory sticks.
- optical storage devices, such as CD, DVD and Blu-ray discs.
- magnetic storage devices, such as hard disk drives.
What’s a PSU on a computer?
Also called a power supply unit or PSU, the component that supplies power to a computer. Most personal computers can be plugged into standard electrical outlets. The power supply then pulls the required amount of electricity and converts the AC current to DC current.
Can Ram store data when the computer is turned off?
Usually, the contents of RAM are accessible faster than other types of information storage but are lost every time the computer is turned off. Non-volatile random-access memory (NVRAM) keeps its data without using power, which is more expensive but works slower, so it is used in smaller amounts.
When power is completely removed from your computer what happens?
A. If a PC completely locks up it can be shut down by holding down the power button for several seconds. However, the PC does not have time to save open files or shut down the Windows operating system properly. This can result in the operating system becoming corrupt and any unsaved data will be lost.

Most laptops have 2.5-inch drives, but ultraportable notebooks may use the 1.8-inch disk size. Also, even 2.5-inch drives can have different thicknesses– 7 mm or 9.5 mm–and different interfaces (SATA or IDE, usually in laptops from 2008 or before).
Is 128gb enough for laptop?
Laptops that come with SSD usually have just 128GB or 256GB of storage, which is enough for all your programs and a decent amount of data. If you can possibly afford it, 256GB is a lot more manageable than 128GB.
Is 512 GB enough storage?
As of June 2015, most SSDs have a storage capacity of 32GB, 64GB, 128GB, 256GB, 512GB or 1TB. In an ideal world, you’d get a computer with one (enough for most users) or even several 1TB SSD drives. That brings us to the second problem.
