In all sequential circuits, the effect of all previous inputs on the outputs is represented by
a state of the circuit. Thus, the output of the circuit at any time depends upon its current
state and the input. These also determine the next state of the circuit. The relationship
that exists among the inputs, outputs, present states and next states can be specified
by either the state table or the state diagram.

Flip flop is an important basic memory element for digital circuit. Flip-flop is designed
by assembling different logic gates. Single logic gate does not have any information
storing capacity but by combining different such gates one can make such a digital
circuit which can store digital information.
Flip flop is such circuit.
Combinational circuits and systems produce an output based on input variables only. Sequential circuits use current input variables and previous input variables by storing the information and putting back into the circuit on the next clock (activation) cycle.
In the above diagram, shown how sequential circuits work.
There are two types of inputs to
The CPU, memory and bus are internal components of a computer.
Everything else is an input or output device .
List of I/O Devices:
- Disk
- Keyboard
- Hard disk
- Speakers
- Floppy
- Printer
- CD
- Mouse
- DVD
- Scanner
- Monitor
- Game controller
- Network
- USB drive, etc.
I/O Controllers:
The input/output controller is a device that interfaces between an input or output device and the computer or hardware device.
The input/output controller on a computer is commonly located on the motherboard.
An I/O controller can also be an internal add-on that can either be used as a replacement or to allow for additional input or output devices for the computer.
Faster read and write compared to traditional hard disk drives. Flash memory is a memory storage device for computers and electronics. It is most often used in devices like digital cameras, USB flash drives, and video games. It is quite similar to EEPROM.

Memory devices in computers are used for storing different forms of information such as data, programs, addresses, textual files and status information on processor and other computer devices. Information stored in memory devices can be divided into bits, bytes, words, blocks, segments, pages and other larger data structures, which have their own identifiers.
In main memory, information is stored in memory cells or memory locations. Memory locations contain information to which an access can take place.
To read or write information in a memory location, a single memory access operation has to be
Memory hierarchy a concept that is necessary for the CPU to be able to manipulate data. This is because it is only able to get instructions from cache memory. Cache memory is located on the processor chip, and is the fastest kind of memory.

If you are reading this then, you should have knowledge about Design Patterns in programming languages. Because, Singleton Pattern is one of the types in design patterns.
Singleton Pattern in java means we have to make a class with which we can create only a single object, not more than one.
So, here i'm giving you the code of writing a java class
Whenever we talk about logic based programs in any programming language then, number pattern and asterisk(*) pattern programs are usually asked. At student level programming i also recommends these type of programs because, these pattern type of programs will clear your basic how you should think while solving real world problems.
Here i'll talk about one of those pattern type programs that is pyramid pattern program specifically in java programming language. Pyramid pattern program is usually asked by teachers to there geek students. So, i think all students while learning any programming language should understand these pattern based programs.
No talks now come to the point.
