State the concept of storage and recursion and apply them.

 .

Concept of Storage in Programming:

In programming, storage refers to the area of memory where data is stored during program execution. There are different types of storage in programming, including stack, heap, registers and caches.

The stack is a region of memory where local variables and function parameters are stored. When a function is called, its local variables ad parameters are pushed onto the stack and when the function returns, they are popped off the stack.

The heap is a region of memory where dynamically located data is stored. This includes data structures such as arrays, linked lists and trees.

Registers and caches are special types of memory that are used to store frequently accessed data, such as variables or instructions.

Understanding how storage works in programming in important for writing efficient code and avoiding memory-related issues, such as memory leaks or buffer overflows.


Concept of Recursion in Programming:

Recursion is a programming technique where a function calls itself to solve a problem. It is a way to solve complex problems by breaking them down into smaller, simpler sub-problems.

In order for a recursive function to work, it must have a base case that specifies when the function should stop calling itself. If the base case is not defined properly, the function will continue to call isled indefinitely, causing a stack overflow and crashing the program.

Here is an  example of how to  implement recursion in JavaScript to calculate the factorial of a number:

function factorial(n) { if (n === 0) { return 1; } else { return n * factorial(n - 1); } } console.log(factorial(5)); // prints 120

In this example, the factorial function takes a number n as input and returns the factorial of that number. The base case is when n is equal to 0, at which  point the function returns 1. Otherwise, the function calls itself with n-1 as the argument, until it reaches the base case.

In conclusion, understanding the concepts of storage and recursion in programming is essential for writing efficient and effective code. By properly managing storage and implementing recursion, programmers can solve complex problems and optimize their programs for better performance.

Introduction of Computer

.  A computer is an electronic device. It take input and store the data in memory and performing the function to produce accurate result in output device. It is used to type document, send email, play game, browse the web and entertainment.   Characteristics of computer  1 . High speed  Computer is very fast device. It is capable of performing calculation of very large amount of data. The computer has unit of speed in microsecond, nanosecond and even in picosecond. The computer is capable of performing millions of tasks per second. 2. Accuracy  The computer produces highly accurate and reliable result.  It does not make any kind of mistake in calculating. The calculation are 100% error free. The computers perform accurate 'n' number of times. 3. Storage capability A computer has much more storage capability. It can store large amount of data. It can store any type of data such as image, video, text document, audio and many more. 4. Diligence Diligence ...

Introduce Linux, UNIX and Linux distribution.

 . Linux Linux is an open source operating system. The term Linux is actually referred to mean a kernel of Unix like operating system developed by a Finish software architect Linus Torvald. The name Linux is derived from Linus' Unix. Linux was originated from the inspiration of a small Unix like operating system MINIX by A.S Tanenbum. Linux is a complete multiuser, multiprocessing, secure and stable operating system which is also considered as UNIX clone. However no code from the proprietary from AT and T is included in Unix. It has flavor of Unix but is not Unix. UNIX  UNIX is a layered operating system. The innermost layer is the hardware that provides the service for the OS. The operating system, referred to in UNIX as the kernel, interacts directly with the hardware and provides the services to the user program. These user programs don't need to know anything about the hardware. They just need to know how to interact with the kernel and it's up to the kernel to provide ...

Open System Interconnect (OSI) Reference Model

 . Open system interconnection (OSI) Model explains how packet travels through various layers to other devices on a network, even if the sender and destination have different types of network media. Layer 1(Physical layer):  Function  To activate, maintain, deactivate the physical connection.  To define voltage and data rates needed for transmission.  To convert the digital bits into electrical signals.  To decide weather the transmission the transmission is simplex, half or full duplex.  Physical layer doesn’t perform the detection and correction of errors. Layer 2 (Datalink layer):  Framing (stream of bits into manageable data units):  The datalink layer divides the stream of bits received from the network layer into frame manageable data units called frames.  Physical addressing (MAC Address):  Data link layer adds a header to header to the frame to define the sender and receiver of the frame. Flow Control (mechanism for overwhel...
