• Binary Cell: A Device that Possesses
Two Stable States
• Cell Input: Receives Data and Control
Signals that Set it to One of the States
• Cell Output: Physical Quantity Indicating
Which State the Cell is in
• States are Encoded as Binary Digits
{0,1}
Registers
• Group of n Binary Cells: an n-bit Register
• Register has 2
n States: All Possible n-bit
Strings
• Register State (or content) can be
INTERPRETED as Value, ASCII, etc.
• Registers Classified as to Type of Input and
Output - Serial and/or Parallel
The universal shift register is a type of sequential logic circuit that is used for the storage or transfer of data in the form of binary numbers and then "shifts" the data out once every clock cycle.
The function of registers is the same in all computers. They are the fundamental binary interface between the internal and external structure of the CPU. All binary transactions between the CPU and its peripherals pass through registers. From the inside, they are the final periphery to the pins.

Main Memory and Registers of just about every computer are based on 64-bit or 32-bit binary integers.

The purpose of any register is to keep records: a register is a database.
both are the storage devices both store the data in binary form both are the costlier
