In order for bitlocker to protect the system volume without the aid of an external drive, your computer must:
a. be 32-bit.
b. host a virtualized enabled bios.
c. be tpm-compatible.
d. have a usb 3.0 interface.

Your computer must be TPM compatible

Explanation:

TPM -> Trusted Platform Module.

For BitLocker’s to have its full-disk encryption on any computer, the computer be TPM compatible.

This TPM creates the original encryption keys of the BitLocker, after which the keys are then saved/stored; that's why the BitLocker needs the TPM to function.

On it's own, it can unlock the computer's drive for the user to login to the system by just typing the login pass phrase.

When you try using BitLocker on a computer without TPM, you'll receive a notification that says your administrator must set a system policy option.

answer; i believe the correct answer is the player pushing down on the floor;

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
