Step-by-step explanation:
the smallest unit of memory is a bit. you would think its a kilobyte or a byte, but actually a kilobyte is just a byte times 1000, and a byte is eight bits! one bit is either 0 or 1 stored in a computer
an erasable cd is called CD-RW it stands for read-write! which means you can erase it! on the other hand a CD-ROM is read only and this would not be the answer.... the answer is CD-RW
this "Which tab is used to apply text effects" question is confusing since we do not know which software you are working with. lets assume its powerpoint.... so then it would be the Home tab, because you can change the font there, no?
the next question is also unanswerable since we dont know which software you are working with...
RAM is called volatile memory. when you open stuff like Chrome on your computer and use it, the tabs are stored in your RAM. also when you play a game and you are in a live online match, the data is stored in your RAM. and when you shut down your computer, your game closes and your Chrome closes :( because its VOLATILE memory which means that all the memory is lost when you turn off the power. volatile memory needs power
