The process by which a method calls itself directly or indirectly, again and again, is called recursion and the corresponding function. Pre-increment operator used incrementing the variable value by one before assigning the cost to the variable. Post-increment operator use to incrementing the variable value by one after assigning the value to the variable. Cell phones, MP3 players are some example of embedded systems in which integrated C is used to program and control these devices.

C language is belonging to middle-level language. C language behaves as a bridge between machine level low level languages and high-level languages. C language is more user-friendly than machine level languages. And, C language does not support all the concepts that high-level languages offer. So, C programming language called as middle-level language. In this type of language, large codes fragmented into small programs called functions.

The main focus is on procedures and functions that operate on values Data moves without any restrictions around the systems from one procedure to another Program structure follows "Top-Down Approach. Data is hidden from functions and cannot access by external functions Program structure follows the "Bottom UP Approach. There is no specific structure rule for programming this language.

Modifiers are fixed with basic data types to modify either increase or decrease the amount of storage allocated to a variable. For example, storage requirements for int data type are 4 bytes for a bit processor. We can increase range by using long int data type which is 8 byte.

We can decrease the range by using short int which is 2 byte. Variable declaration tells the compiler about data type and size of the variable. Whereas, variable definition allocates memory to the variable. Variable can be declared many times in a program. But, the definition can happen only one time for a variable in a program.

Variable declaration is for assignment of properties and identification to a variable. Whereas, a variable definition is for assignments of storage space to a variable.

This concept is an essential part of the runtime polymorphism portion of object-oriented programming OOP. Overloading is a process used to avoid redundant code where the same method name used multiple times but with a different set of parameters. The actual method that gets called during runtime is resolved at compile time, thus avoiding runtime errors.

In any object-oriented programming, Overriding is a process that allows a child class or subclass to provide a specific implementation of functions that is already provided by one of its super-classes or parent classes. By using the ability of polymorphism an object can take on multiple types. The frequent use of polymorphism occurs when a parent class refers to an object of the child class. The Java object that can pass more than one IS-A test is polymorphic.

In oops, abstraction is one of three main principles along with encapsulation and inheritance. Through the process of abstraction, a programmer hides all but the relevant data about an object to reduce complexity and increase efficiency. Encapsulation is one of the primary concepts in object-oriented programming. It describes the idea of combining data in a single class and methods that work on that data, e.

This concept is also often used to preserve the internal state, of an object from the outside. In object-oriented programming, inheritance helps new objects to take on the properties of old objects.

A class that uses for inheritance is called a base class or superclass. A class that inherits data from a base class is called a subclass or derived class. A constructor is a method which is used to initialize a newly created object and is called just after when memory allocated to the object.

It can be used to implement the objects to desired values or default values at the time of object creation. A destructor used when the initialized object is destructing it called automatically during the destruction of an object. It helps in recovering the heap space and remove files. Data Structure is a process in which management or organization of data that enable a more efficient way to organize the data.

A linked list is a set of ordered data and each of its previous nodes connected to its succeeding node. It is like an array but more efficient then array because we can insert or delete data in between the nodes. It is also known as ordered or sorted binary tree.

It keeps there nodes or keys in sort form, and the root node of BST is bigger than the left node and smaller than the right node. A binary tree is part of a data structure that has two sub-nodes, a right node, and a left node.

In programming, binary trees are an advanced version of the linked list. Pushing and popping applies to the way data is stored and fetched from a stack. A push method denotes data being added to it, meaning information is being "pushed" in the stack. A stack base on LIFO pattern. It means that data access follows a sequential process wherein the last data to be entered when the first one deleted.

Arrays do not follow a particular order and instead can access by referring to the indexed element within the array.

Doubly linked lists are a particular part of linked list wherein traversal across the data elements can be done in any directions. This is possible by having two links in every node, one that connects to the next node and another one that links to the previous node.

A Queue is a data structure which is linear and follows a fixed order in which the operations occur. An excellent example of a queue is any queue of the customer for a resource where the customer that came first served first. The difference between stacks and queues is while deleting. Basic features of Stack are an ordered list of the similar data type. The interconnection of objects are represented by points termed as vertices, and the links that connect the vertices are called edges. A priority queue is an abstracted data type which is like a queue or stack data structure, but where additionally each element has a "priority" associated with it.

In a priority queue, an element with high priority is served before an element with low priority. JavaTpoint offers too many high quality services. Mail us on [email protected] , to get more information about given services.

Computer Graphics. Index hunting is the method of boosting a collection of indexes. This is done because indexes improve query performance as well as query processing time.

In SQL, a view is a single table that contains data from other tables. As a result, a view features rows and columns that are identical to those of a real table, as well as fields from one or more tables. In the above queries, Column1, Column2,.. ColumnN denotes the name of the columns to be added or updated. SJF Shortest Job First is a scheduling policy that prioritizes the waiting process with the shortest execution time.

It is a scheduling algorithm that is not preemptive that is, one process cannot snatch the resources assigned to a currently running process. The procedure, next in the queue, with the least amount of time till completion is chosen to be executed in this scheduling technique. One of the factors is that it is dependent on how frequently a deadlock is likely to occur when this algorithm is implemented.

The other is the number of processes that will be affected by deadlock if this algorithm is used. In dynamic loading, a routine is not loaded until it is called. This strategy is very effective when dealing with vast quantities of code, such as error routines, that occur infrequently.

All routines are saved in a relocatable load format on the disk. The main program is executed after it has been loaded into memory. When a routine requires to call another routine, the calling routine checks to verify if the other routine is loaded first. If this is not the case, the relocatable linking loader is used to load the requested routine into memory and update the program's address tables.

The newly loaded routine is then given control. In this way, dynamic loading helps in better memory space utilization. The root partition is the place where the operating system kernel is located.

Other potentially crucial system files that are mounted during boot time are contained in it as well. An abstract layer on top of a more concrete file system is a virtual file system VFS or virtual filesystem switch. Caching is a technique for saving numerous copies of the most frequently used data in a temporary storage area or cache so that they can be accessed more quickly. It keeps data in a temporary format for software applications, servers, and web browsers, so users don't have to download information every time they visit a website or use an application.

Cached data works by saving data in a device's memory for later access. The data is kept in the memory of a computer, directly below the central processing unit CPU. The primary cache level is incorporated into a device's microprocessor chip, followed by two more secondary cache levels that feed the primary level. This information is kept until the content's time to live TTL , which specifies how long it should be cached, expires or the device's disc or hard drive cache fills up.

Data is usually cached in one of two ways: browser or memory caching data stored locally on the computer or Content Delivery Networks data stored in geographically distributed locations. Preemptive multitasking permits computer programs to share operating systems OS and underlying hardware resources. It distributes the overall operating and computing time amongst processes, and it uses established criteria to switch resources between processes. Time-shared multitasking is another name for preemptive multitasking.

The operating system never initiates context switching from one process to another in cooperative multitasking. Only when the processes voluntarily cede control on a routine basis, or when they are inactive or logically blocked, does a context switch occur, allowing many applications to run at the same time. In addition, in this multitasking, all processes work together to make the scheduling strategy work.

For instance, Instead of delivering a folder or drive listing to the main screen, it can be piped and delivered to a file, or sent to the printer to print a hard copy. A trapdoor is a software or hardware mechanism that can be used to bypass system controls. In general, it's malicious software that allows an attacker on the other side of the Internet to gain unauthorized access to a computer system or network by accepting remote commands.

The TLB includes the most recently used page table entries. The frame number is retrieved and the real address is created if a page table entry TLB hit is present. If a page table entry is missing from the TLB TLB miss , the page number is used as an index while processing the page table. The TLB first checks if the page is already in main memory; if it isn't, a page fault is generated, and the TLB is then modified to incorporate the new page entry.

At any given time, the resident set is the part of the processed image that is actually in the real memory. It's broken down into subsets, one of which is the working set. The working set is the subset of the resident set required for execution.

A bridge router, sometimes known as a brouter, is a network device that can function as both a bridge and a router. The brouter forwards all other packets like a bridge and only routes packets for known protocols. For routable protocols, brouters function at the network layer, while for non-routable protocols, they operate at the data link layer. Brouters operate as routers for routable protocols and bridges for non-routable protocols, handling both routable and non-routable characteristics.

Brouters are connecting devices in networking systems that serve as both a network bridge and a router in the internetwork. The Exterior Gateway Protocol EGP is a protocol that allows Internet gateways from the same or separate autonomous systems to share network reach-ability information. Rather than communicating in native "languages", all Telnet clients and servers agree to deliver data and commands that conform to a fictional "virtual" terminal type known as the Network Virtual Terminal NVT.

The NVT specifies a set of standards for formatting and sending data, including character set, line termination, and how information about the Telnet session is provided. Every Telnet client on a terminal can communicate in both its native language and NVT. When a user enters information on his or her local terminal, it is translated to NVT and sent over the network in that format.

When the Telnet server receives this information, it converts it from NVT to the format required by the remote host. In reverse, the same procedure is followed for transmissions from the server to the client. The Hamming code is a set of error-correction codes that can be used to detect and fix errors that can arise when data is transferred or stored from one source to another. Redundant bits are extra binary bits that are created and added to the data transfer's information-carrying bits to ensure that no bits are lost during the data transfer.

A parity bit is a bit that is appended to binary data to verify that the total number of 1s is even or odd. Error detection is done with parity bits. The Hamming Code is essentially the use of additional parity bits to allow for error detection. A bidirectional communication channel is provided by a pair of virtual character devices known as a pseudo TTY or "PTY". The master is at one end of the channel, while the slave is at the other. The pseudo-terminal's slave end provides an interface that is identical to that of a conventional terminal.

A process that expects to be connected to a terminal can open the slave end of a pseudo-terminal, which will subsequently be controlled by a program that has opened the master end. Anything written on the master end is supplied to the slave end's process as if it were any input entered on a terminal. Anything written to the slave end of the pseudo-terminal, on the other hand, can be read by the process linked to the master end.

Network login services, terminal emulators, and other such applications employ pseudo-terminals. BufferedWriter is a temporary data storage source. It's used to make a buffered character output stream with the default output buffer size. To flush characters from the buffered writer stream to a file, the flush function of the BufferedWriter class in Java is employed.

It ensures that all data items, including the last character, are written to the file. The close function of the Java BufferedWriter class flushes the characters from the buffer stream and then closes it. Calling methods like write and append after the stream has been closed will generate an error. The stack is a section of memory that stores information about nested method recursive calls all the way down to the present program location. It also holds all local variables and heap references defined in the currently running procedures.

This structure enables the runtime to return from the method knowing the address from which it was invoked, as well as to remove all local variables when the procedure has been exited. Every thread has a stack of its own. The heap is a big chunk of memory used for dynamic allocation.

When you use the new keyword to create an object, it is allocated on the heap. The reference to this object, on the other hand, is stored on the stack. The Garbage Collector GC must call the finalize method on an object when it becomes garbage collection eligible. Because the finalize method can only be used once, the GC marks the object as finalized and sets it aside until the next cycle.

You can technically "resurrect" an object in the finalize method by assigning it to a static field, for example. The object would revive and become ineligible for garbage collection, preventing the GC from collecting it in the next cycle. The object, on the other hand, would be marked as finalized, thus the finalize method would not be invoked when it became eligible again.

In essence, you can only use this "resurrection" method only once. The finalize method adds the items to the collection once and then resurrects them. They have been marked as finalized and will not be queued again when they are collected a second time. Because static methods are resolved at compile time, one cannot override them in Java. Because objects are only available at runtime, overriding requires a virtual method that is resolved at runtime. In Java, a static method can be overloaded.

Overloading has nothing to do with runtime, but each method's signature must be distinct. To alter the method signature in Java, either the number of parameters, the type of arguments, or the sequence of arguments must be changed. In Java, you can't override a private method because the subclass doesn't inherit the private method, which is required for overriding.

In fact, no one outside the class can see a private method, and a call to it is handled at compile time using Type information rather than at runtime using the actual object.

Monkey patches are dynamic or run-time alterations of a class or module in Python. We can truly change the behavior of code at runtime in Python. In the code below, we use the above module m to change the behavior of func at runtime by assigning a new value. The logic shown below is a simple Half Adder that may be used to add two single bits. This logic can be extended to integers. All carry bits are obtained by bitwise AND of a and b. Let's have a look at how this works.

The term "non-datatype" refers to a value rather than a datatype. In the preceding code, for example, N is passed as a value rather than a datatype. For each parameter, a new instance of a generic class is constructed, and these classes are created at compile time.

It is commonly used to observe and determine the LAN address from the main network address. And, for the nodes to transfer individual frames through the local link, a link to your address is required. This is where ARP helps. It first sends a broadcast message to the available nodes to state the MAC address of the IP address in question, allowing easy flow communication through the same. A code snippet refers to a small block of code that is reusable and can easily be inserted in any court file using the context menu, also known as the right-click menu command, or by using different combinations of the available hotkeys.

One code snippet can contain a list of reusable code blocks and can easily be inserted into either the entire method or the entire class. It is the place wherein an operating system kernel is placed along with the crucial system files that are potentially held up in other places during boot time. In a programming language, the routine is never loaded until it is called, especially when it comes to dynamic loading.

It is a strategy that is highly effective when there is a high quantity of courts including the error routines that can occur infrequently. To save a routine, a relocatable load format is necessary on the desk. Once the main program is loaded into the memory of the system, it is executed and at the same time, each routine requires the next routine to follow. However, to verify whether the routine required to follow is loaded or not, the relocatable linking loader is needed to load the requested memory retain to update into the current program address tables which is done using dynamic loading, while optimizing memory space utilization.

A storage structure is a type of data storage wherein the main data is directly stored in the prime memory that is called RAM. Once the data stored is there, as soon as the function that uses the respective data is done with the complete execution, it is directly deleted. A file structure on the other hand is the type of data representation that is stored in the auxiliary or secondary memory of any device like pen drives and hard drives.

The main purpose is to store data and keep it intact until it is deleted manually. One of the main functions or the ability of polymorphism is that it can permit an object to take on different types, in terms of other objects. When polymorphism is used frequently, a generic class, parent class or base class is a part of the object within a child class.

Any object within Java that passes more than one test called IS-A, is known to be polymorphic. The first disadvantage of the classic life cycle model is that the working version of this particular program is not yet available. So, any customer will have to have a lot of patience to work with it. The second disadvantage is that when it comes to real projects, very rarely do they follow the sequential flow. And, for the same reason, division occurs and creates unexpected problems.

Lastly, another disadvantage of the classic life cycle model is that it is relatively challenging for any customer to directly state and ask for all the requirements. For this technical question, it is important to keep in mind that the answer should be direct and consist of all the necessary features of the software configuration management. It is the process of controlling and talking about all the changes that take place within a software.

It has a function called change control that monitors all the changes that are made in a software system, while also ensuring that they are consistent and use the same rules and regulations of an organization.

When it comes to the time complexity of deletion or insertion, especially in a singly linked list, it is directly dependent on the position in the software where you want to perform the respective command. For instance, if you want to add an element towards the end of the linked list during insertion, you have to either travel or transfer the entire list, making the complexity O n. Under this model, there are four layers including the process or application layer, the host to host or transport layer, the internet layer or network layer, and the network access or combination of physical and data link layer.

Commonly known as a brouter, a bridge router is a network device that can work as both a router and a bridge. The main function of the bridge router is to forward all the different packets including a bridge, with known protocols, and other route packets. When it comes to routable protocols, it is at the network end that the bridge is out of function.

However, on the other hand, when they operate on the data link layer, they are known to be non-routable protocols.

In simple words, the bridge router can successfully handle the characteristics of both non-routable and routable protocols with ease. Within a network system, the bridge router is unknown to be the connecting device that helps as either a network bridge or a router within the internet work. The resident set and the working set are correlated. When it comes to a resident set, it is part of the chosen processed image which is stored in the real memory location.

When the processed image is broken down for use in two separate subsets, each of these subsets is known as a working set. Therefore, the working set is necessary as it is an essential part of the resident set, needed for correct execution, and acts on memory. The pre-increment operator is used to denote the value of a particular variable right before adding it to an expression. When it is about pre-increment of the latter, it is the value that is incremented first and then is used within an expression.

The post-increment operator, on the other hand, is used to denote the value of a particular variable after the expression execution is completed. When it is in regards to the post-increment operator, it is the value that is used first within an expression and then the increment takes place.

However, in some cases, a programmer may not remember to destroy the unnecessary objects, using up more memory location space, suffocating the limited memory available causing memory leaks. Java garbage collector function system. GC is a procedure through which a programming language like Java benefits from the automatic management of memory.

Hamming code is a set of error correction codes that can be used to detect and correct errors that may occur when data is transferred or stored from one source to another. Unnecessary fragments are additional binary bits that are built and added to the data transfer bits to ensure that no bits are lost during data transfer.

A parity bit is a small number attached to binary data to ensure that the total number of 1s is equal or not equal. Hamming code is the actual method used for additional measurement components to allow for error detection.

It is a feature to fill the percentage of space on each level page that will be filled with data. The smallest unit in the SQL server is a page, made up of 8K pages. Depending on the size of the line, each page may contain only one or more lines. The default fill factor value is , which is equal to the value of 0. The SQL server will fill index-level pages with the maximum number of lines that can be entered if the fill factor is set to or 0.

If the fill factor is , then the page will not have space or minimal space. Index hunting is a way to improve a collection of clues. This is because the indicators improve the performance of questions and the time to process them.

Monkey function is available in Python programming language. And, it is also known as monkey patching. Using this, a programmer can modify a code at runtime for a class or a module. With the help of this monkey function, it is easier to reopen a module or a class for behavior alteration to complete a project, using code at runtime. Caching is a way of saving multiple copies of data that are widely used in temporary storage or archive for quick access. It stores data in temporary formats for software applications, servers, and web browsers.

So, users do not have to download information every time they visit a website or use an application. Cached data works to save data to device memory for later access. The data is stored in computer memory, directly below the central processing unit CPU.

The primary cache level is installed on the device's microprocessor chip, followed by other secondary cache levels that feed the primary level. This information is stored until the life of the content, which specifies how long it should be stored in the archive, expired.

Proactive Updates: These changes were made to the website before use in the real-world environment. Retroactive Updates: These updates are applied to the website after it has worked in the real world. Simultaneous Updates: These updates are applied to the website at the same boot time as they first came into effect in the real world.

One of the main factors that help influence whether or not the need for a detection algorithm is required is that it is directly dependent on the frequency of a deadlock occurrence each time the algorithm is implemented.

Other than this, the number of processes that will be directly or indirectly affected due to this deadlock as soon as the algorithm is put to use is another determining factor. The presence of an abstract layer right on top of a more specific and concrete file or system is called a virtual file system. The main purpose of a virtual file system is to allow various client applications to easily access a variety of different concrete file systems regularly.

Lastly, it is used to define a kernel interface within a particular file system which adds more support to the new file system which is being implemented in the kernel. Some of the most common elements of a processed image include the user data, user program, and overall process control block.

An exterior gateway protocol allows all the different internet gateways from both the same or separate systems to easily share information on network reachability. There are three purposes for it, including:. In programming languages , BufferedWriter is known to be a temporary source of data storage used to create an output stream for a buffered character with the use of the default output buffer size. Using the recursion process, any method can call itself indirectly or directly, as many times as needed.

And, this process is also called the corresponding function. The key characteristics of the OFC language include flexibility, modularity, portability, reliability, interactivity, efficiency, and effectiveness. The main purpose of a modifier is to derive the necessary space for variable allocation. All the modifiers are fixed and consist of basic data types that can either be increased or decreased based on the amount of variable storage allocation.

It is an essential core part of polymorphism called runtime. For all developers, the actual meaning of inheritance is the ability of new objects to take on some of the old properties of the previous objects without any concerns. For instance, when a class uses inheritance, it is called a base class or a superclass. On the other hand, when the class inherits data from the main base class, it is either called a subclass or a child class. The popping and pushing of data are known to be how data is fetched and stored from a particular stack.

With the post method, it means adding data to the stack and with the pop method, it indicates data retrieval. Among all the different programming languages, the C language is known as the middle-level language. It is a bridge between the low- or machine-level languages and the other high-level languages.

This is a commonly used language as it is highly user-friendly and offers multiple support options.
