Hi! Nice to E-Meeting You. 

Does my cat speak English! How?  Yes, Learn to communicate in English. Ask How?

I have my science and thoughts on teaching and learn new things, which can help you to speak English easier and faster!

  • Practice makes perfect!
  • Please keep it simple.

There is no magic to learning faster English, but Practicing English is the best way to learn quickly.

"My cat speaks English."

"Sometimes my cat comes to me and tells me that she is hungry. Or that her leg hurts. How does my cat tell me these things? I don't speak pussycat language. "

Everyday science on the best ways to learn English faster:-

  • Read everything you can get your hands on
  • Focus on Speaking – Not on Grammar
  • Talk to yourself in English.
  • Talk with real live humans; the mirror is alternative. 
  • Learn what you like
  • Use every way you can to communicate.
  • Immerse Yourself in the Language
  • Practice with a Friend
  • Watch English speaking movies.
  • Write stories
  • Record yourself speaking
  • Listen and watch
  • Accept help from other people.
  • Actively take note of new vocabulary.
  • Practice with natives, no matter your level!
  • Don't give up

One Last Thing…

We live in a society where we are always trying to speed things up, but language learning is a process. It will not happen overnight and must be prepared to dedicate time and energy to learning English.

It is an investment in your future, so don't take shortcuts.

What is an Algorithm?

An Algorithm is a step-by-step procedure, which defines a set of rules to be executed in a specific order to get the desired output.

Characteristics of Algorithm:

  • Language independent
  • Feasible
  • Unambiguous
  • Finiteness
  • Well-define input
  • Output (should match the desired output)

Analysis of Algorithm

Analysis of the algorithm is the process of analyzing the problem-solving capability of the algorithm in terms of the time and size required. There are two different stages to perform efficiency of an algorithm, before and after implementation.

Complexity of Algorithm

The complexity of an algorithm is a measure of the amount of time and/or space required by an algorithm 

 Time Complexity:   An amount of time that needs to execute an algorithm.

 Space Complexity: A storage of memory that requires to execute an algorithm

 How to design an Algorithm.

Design an algorithm to add two numbers.

Step 1 − START

Step 2 − declare three integers a, b & add

Step 3 − define values of a & b

Step 4 − add values of a & b

Step 5 − store output of step 4 to add

Step 6 − print add

Step 7 – STOP

The distinction between Analog and Digital (Signals & Systems)
Sr.No.
Analog Signals/Systems
Digital Signals/Systems

1
Analog Signals are continuous signals.
It is the one which changes between two discrete levels of Voltage.

2
It is having an infinite set of possible values.
It can have finite values.

3
Signal Generators, Transducers are some of the sources used to generate analogue signals.
Computers, A to D Converters etc. are the sources of digital signals.

4
These are described by parameters like Amplitude, Time Period, Frequency, and Phase.
Digital Signals are described by Bit Interval (instead of Time Period) & Bit Rate (instead of Frequency).

5
These are less accurate.
These are accurate & precise as compared to analogue systems.

6
Storage of information is not possible.
Storage is possible, e.g. in computers, USB etc.

7
These are very much affected by noise.
These are less prone to noise (have much more immunity).

8
These are difficult to design.
These are easier to design.

9
These have more memory due to which storage is not possible.
These have memory.

10
These cannot be fabricated on IC’s.
These can be fabricated on IC’s.

11
The Material used to design analogue systems is prone to wear & tear e.g. spring’s elasticity decreases day by day. Thus these have lesser (or small) life.
Digital systems have larger life as compared to analogue systems.

12
Programming is not possible.
A set of instructions can program digital systems.

13
Data is displayed on Analog Meters etc.
Data is displayed on LCD’s, LED’s, Nixie Tubes etc.

14
e.g. Filters, Amplifiers, Power Supplies, Signal Generators etc.
Counters, Registers, Microprocessors, Computers etc.

Logic Simplification

Simplification of Boolean functions is mainly used to reduce the gate count of a design. Less number of gates means less power consumption; sometimes the circuit works faster and also when the number of gates is reduced, cost also comes down. There are many ways to simplify a logic design; some of them are given below.

Algebraic Simplification Simplify symbolically using theorems/postulates.

Karnaugh Maps Diagrammatic technique using 'Venn - diagram.'

Basic Laws of Boolean Algebra

Commutative law

A + B = B + A
A . B = B . A

Associative law

A + (B + C) = (A + B) + C
(B.C) = (A.B).C

Distributive law

(B + C) = A.B + A.C

Other laws of Boolean algebra

A + 0 = A
A + 1 = 1
A + A = A
A + Ā = 1
A .0 = 0
A .1 = A
A .A = A
A . Ā = 0
=
A = A
A + A.B =A
A.(A + B) = A
(A + B).(A+C) = A +B.C
A + Ā.B =A + B
A.(Ā +B) = A.B
(A + B).(Ā + C) = A.C + Ā.B
(A + C).(Ā + B) = A.B + Ā.C

Memory can be divided into two types:

1. Primary memory

2. Secondary memory

1. Primary memory 

It is a temporary memory where data can be stored temporarily, and this primary memory is again divided into two types there are RAM and ROM 

RAM - abbreviation of RAM is randomly accessible memory it is used to.speed up your computer, and these are called as volatile memory. This RAM is divided into two types there are static RAM and dynamic RAM.

ROM- an abbreviation of ROM is read-only memory where these is also called non-volatile memory again this ROM is divided into 3types there are 

           1.PROM

           2.EPROM

           3.EEPROM

2 SECONDARY MEMORY:

These are also called permanent memory where every data in the computer is stored here there are many types in secondary memory there are HDD SDD CD FD etc. are the secondary memory examples.

The actual size to int is determined by the compiler as the program runs. But theoretically the size is 2 bytes. You can increase the size by adding keyword long infront of it to make the size 4 bytes. Eg int a; // 2 bytes Long int b; // 4 bytes
