Definition: Analytical Engine is known for the world’s first special-purpose mechanical computer and set the blueprint for the modern computer. It is designed by famous English Mathematician Charles Babbage between 1834 and 1846. Charles use brass gears to built the Analytical Engine, it's not electric that is powered by steam engine.

Arithmetic Logic Unit (ALU): A subunit within a computer's central processing unit. ALU alu full form is Arithmetic Logic Unit , takes the data from Memory registers; ALU contains the logical circuit to perform mathematical operations like subtraction, addition, multiplication, division, logical operations and logical shifts on the values held in the processors registers or its accumulator.

What is 32-bit: 32-bit tells us that the number of bits that can be processed or transmitted. In another way, you can say that the number of bits that can be used for the single element in a data format.
32-bit is a type of CPU (Central Processing Unit) architecture that can transfer 32 bits of data per clock cycle or you can say that it is the amount of information that the CPU can process every time it performs an operation.

What is CPU: It's meaning is Central Processing Unit.  Sometimes referred to simply as the central processor or Nerve Centre or heart, but more commonly called processor, the CPU is where most calculations take place. The CPU is the brains of the computer.

What is Computer : Computer is an electronic device that is designed to work with Information. The term computer is derived from the Latin termcomputare’, this means to calculate or programmable machine. Computer can not do anything without a Program. It represents the decimal numbers through a string of binary digits. The Word 'Computer' usually refers to the Center Processor Unit plus Internal memory.

Primary memory is also known as main memory or may also refer to "Internal memory." and primary storage. All those types of computer memories that are directly accessed by the processor using data bus are called primary memory. That allows a processor to access stores running programs and currently processed data that stored in a memory location.

Secondary memory is also known as secondary storage. The secondary memory is accessed indirectly via input/output operations. This memory is also called permanent, external, stable or persistent memory. It is characterised by its slowness and cheapness, relative to the RAM, and by its permanent appearance.

Memory is an essential component of the computer. It is a hardware device that assembled on the motherboard for storing data and instructions for performing a task on the system. Two types of memory are used by the computer, one for storing data permanently and second for operating.

Definition: SDRAM stands for Synchronous Dynamic Random Access Memory. SDRAM operates more efficiently as it works according to the synchronization of the clock. This makes it easy to manage faster, and the speed of the SDRAM measured in MHz instead of nanoseconds. SDRAM introduced in 1969-70. It most widely used in computers. Nowadays it is also used in other systems.

Definition: NVRAM stands for Non-Volatile Random Access Memory. It is a kind of RAM that can store the data even when there is no power. Ex:- Flash memory is a kind of NVRAM.
