Answer:

Ram which stands for random access memory, and Rom which stands for read only memory are both present in your computer. Ram is volatile memory that temporarily stores the files you are working on. Rom is non-volatile memory that permanently stores instructions for your computer

Answer:

Ok so RAM is Random-Access-Memory.

RAM can store data just like in a hard drive - hdd or solid state drive - ssd

but the thing is that ram is really fast and data is only stored when RAM chips get power. On power loss your all data will be lost too.

ROM thanslates to Read-Only-Memory - so data in ROM chips can't be modifyed computer can just read the data but not write.

Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware.

Have a great day.

Answer:

True

Explanation:

Storing gathered multimedia files for an instructional video in a single folder is good practice because this method makes it easier for the user to access and manage the files. The files can also be easily transferred if there is need to since everything is stored in one central area.

Keeping a record of the source information is also important as this helps the instructor to control files and have quick access to any of the files.

2 negative impact of excessive use of computer even in solving mathematical problem.
zlopas [31]

Answer:

Computers are now a days the very important part of each department as well as homes. All people are somehow using computers for their respective needs. As technology always has the negative impacts along with the positive ones so, computer do have some crucial points when taking about students specially.

Following are listed some acts that add to the negativity of computer's usage.

  • Excess use of computers by students while solving mathematical problems lead them to rely totally on the computer. Students don't tend to calculate by their own instead they use computerized calculators for their ease and hence they start lacking even in basic calculations in normal routine also.
  • Computers may impact students routine in such a way that they don't concentrate on their studies while having extreme interest in video games and their favorite seasons and other activities.
  • Using computers more than a certain limit effects eyesight badly. This is the reason today most of the teenagers use spectacles in normal routine.
