because of virus.the virus makes the file corupted and it lose the data
Unfourtunately, you can't, you will have to reenter the data.
It is the level of secondary storage that retains data when power is turned off. For example: Memory is volatile if it loses its data when the power is removed.
true
Computer cannot loose data when is turn off or it is off.This may happen if the computer is infected by a virus.This may also happen if the drices are faulty and do not store data properly.Actualy the data sved on hard disk is always saved there you can run that hard disk in other computer to verify if your computer crashed.
Primary memory are volatile in nature. Eg. RAM. This memory loses data when computer is switched off.
In database system one of the main feature is that it maintains data integrity. When integrity constraints are not enforces then the data loses its integrity.
Yes, it can, because when your hard drive crashes it loses valuable data (something you were working on when it happened) and it generally crashes because of a virus or changed configuration. If you use a data recovery service they will restore whatever work you lost as well as restoring your computer to it's last "working configuration" (so no viruses).
Dynamic RAM
Lossy= Is generally more effective but when opening file it loses some data. This is most noticeable in compressed pictures Lossless= Is the most common method of compression and loses none of the data
The data is CMOS is on a chip called RAM. RAM will lose data when it loses power. A small battery on the motherboard is used to keep continuous power to CMOS when the PC loses power.
Nope...well not enough to fill up you computer but id say about .05% of your computer will be filed up with "junk"...say if your computer can hold 150GB of data then watching youtube videos will fill up about 100-200MB of data if you watch videos everyday for a year. So that's about the size of a 20 minute video.
