What is Storage?
Does our PC come with Storage?!?!
Facts about Internal Hard Disk
A hard drive – or hard disk drive, or HDD – is your PC’s primary area of mass storage. When you copy a file to your PC, that’s where it ends up. Most hard drives consist of a precisely aligned magnetised disk, a high-speed motor, and a read/write head, all in a tough case that prevents dust from reaching the sensitive components within.
Are USB hard drives different?
USB hard drives barely differ from the internal variety. In fact, most external hard drives use identical components – a standard hard drive screwed into a plastic shell. The only difference is the interface – your external drive has some electronics that convert its standard connection to one that can be plugged into the outside of your machine. This process, and the fact that a USB connector is slow compared to an internal hard drive interface, means external drives aren’t as nippy.
Will filling my hard drive slow my PC?
Storing files on your hard drive won’t slow down your PC. That’s its job, after all.
But storing too many files is another matter. Windows uses hard disk space as additional memory. Should your hard drive reach close to its capacity, you’ll notice some sluggishness, because Windows can’t get its hands on the space it needs to run smoothly
t's important to note that USB flash drives should not be used for long-term storage, as they usually don't last as long as a regular hard drive. Flash drives are best used as a short-term storage and transfer tool.
Not all USB flash drives are created equal, and our lineup is here to show you which ones are the very best.

Advantages vs disadvantages
What are registers?
Registers are small, very fast circuits that store intermediate values from calculations or instructions indie the CPU.
There are many small units, registers, but the most important are :
This is the Memory Address Register.
This is connected to the address bus.
Its main function is to contain RAM address for the instruction that the CPU needs next.
This is the Memory Data Register
It is connected to the Data Bus
The MDR holds data that is needed to be written to the RAM, or has been read from the RAM

The term "accumulator" is rarely used in reference to contemporary CPUs, having been replaced around the turn of the millennium by the term "register." In a modern computers, any register can function as an accumulator.
The most elementary use for an accumulator is adding a sequence of numbers. The numerical value in the accumulator increases as each number is added, exactly as it happens in a simple desktop calculator (but much faster, of course). Once the sum has been determined, it is written to the main
