What is a Computer Network?

The connection between two or more computing devices utilising a media is what is known as a computer network. Here, the medium facilitates information sharing among these connected devices. Printers, routers, DVD players, and other pertinent devices can all be connected to these devices, regardless of whether they are personal PCs, servers, mainframes, or other computer equipment.

The use of networking mediums like bridges, cables, routers, and satellites makes these networking activities possible. One well-known example of a networking medium that connects numerous devices is the internet. Devices can transfer data or information most easily thanks to it.

These connected devices are now essential since they make it possible to access emails and share all the resources required. However, these computer networking systems offer a number of other advantages in addition to the ability to share data.

Features of Computer Networks 

Performance

Response time is a common metric used to assess computer network performance. Sending and receiving data from one node to another should have a quick response time (a node is a computer in a computer network).

Data Sharing

We utilise computer networks, among other things, to share data among several systems that are linked to one another via a transmission medium.

Backup

In order to retrieve data more quickly in the event of a breakdown, a computer network must include a central server that maintains backup copies of all the data that will be exchanged over the network.

Software and hardware compatibility

A computer network should allow for better compatibility between various software and hardware configurations rather than forcing all of the machines to utilise the same software and hardware.

Reliability

The network shouldn't fail, or if it does, recovering from a failure should happen quickly.

Security

A computer network needs to be secure in order to protect the data being transmitted across it from unauthorised access. Additionally, there should be no data loss during transmission and the supplied data should be received at the receiving node in its original form.

Scalability

A computer network needs to be scalable, meaning it should always allow for the addition of more computers (or nodes) to the network's already established configuration. For instance, suppose a company runs 100 computers over a computer network for its 100 employees. If the company hires an additional 100 employees and wishes to add the additional 100 machines to the existing LAN, the local area computer network should permit this.

Top Advantages of Python Programming Language

Dennis Ritchie created the procedural general-purpose computer programming language C at AT&T Bell Labs in the early 1970s. It was created as the B programming language's successor to address the shortcomings of BASIC, B, and BPCL. It had both the complex features needed to programme an operating system and high-level functionality. C programming became one of the most popular programming languages throughout the 1980s and is now used to build mainframes, microcomputers, and minicomputers.

The popularity of C is unaffected by the advent of various new languages like Java, Python, JavaScript, and PHP. These languages actually take a lot of their control mechanisms and other fundamental elements from C.

Features of C Language

Simple and Efficient

The fundamental grammar used to build the C language is fairly straightforward and simple to learn. This facilitates a programmer's ability to rebuild or develop a new application and makes the language simple to understand. Because of this characteristic, C is frequently used as an introductory language to teach programming to school pupils.

Fast

The speed advantage of statically typed computer languages over dynamic ones is well recognised. C has an advantage over other dynamic languages since it is a statically typed programming language. Also, C is a compiler-based programming language, in contrast to Python and Java, which are interpreter-based. As a result, coding compilation and execution are expedited.

Note: If you have trouble with programming, take our Python Programming Help from experts.

The availability of only the necessary and essential functionality makes C quick, as well. Numerous features in more recent programming languages boost functionality but decrease efficiency and speed. Since C only provides a few basic but necessary capabilities, processing these features is simplified and speed is consequently boosted.

Portability

The portability of the C language is another benefit. Simply put, C programmes are machine-independent, allowing you to run parts of the code written in them on different machines with little to no machine-specific modifications. As a result, depending on the need, it offers the functionality of employing a same code on numerous systems.

Extensibility

A C programme can be simply (and quickly) extended. As a result, you can easily add new functionality to existing code that has already been written. In essence, it enables the addition of additional functions, features, and operations to an already-existing C programme.

Note: If you have trouble with your assignment, take our C sharp assignment help from experts.

Function-Rich Libraries

Programmers' lives are made simple by the vast number of libraries and built-in functions that C includes. These built-in utilities make coding simple enough for even beginners. Additionally, you can develop your own user-defined functions and include them in C libraries. A programmer can create a wide variety of programmes and apps thanks to the availability of such a broad range of functions and operations.

Dynamic Memory Management

The ability for dynamic memory management in the C language is one of its most important features (DMA). It implies that you can use and control the data structure's size in runtime in C. Additionally, C offers a number of built-in functions for handling memory allocation. For instance, you can always release the memory that has been allocated by using the free() method. Similar operations can be carried out on data structure and memory allocations using other techniques like malloc(), calloc(), and realloc().

7 Various Ways To Do Features Of Python Language

 Programming languages were formerly solely known to software developers. Due to the development of new technologies, programming knowledge is now required for the majority of non-developer positions as well. As a result, there is a need for a straightforward programming language that is simple to learn and that can also enable quick iterations and efficient development. All of these requirements are satisfied by the language Python. Python is one of the top programming languages of 2020, according to the TIOBE Programming Community Index. Python's popularity is growing because it is used in booming industries like artificial intelligence, data mining, and numerical computing.

Python Features and Advantages

Some of the Python features covered below include the following:

Easy to Code

Despite being a relatively advanced programming language, Python is simple to learn. Python coding may be learned by anyone in a matter of hours or days. It can take some more time to fully understand all of Python's complex concepts, packages, and modules. However, compared to other well-known languages like C, C++, and Java, understanding the fundamentals of Python syntax is quite simple.

Easy to Read

Python code resembles everyday English terms. The code block is defined by the indentations rather than by semicolons or brackets. Simply by glancing at the code, you can determine what it is designed to perform.

Note: If you have trouble with your assignment, take our C sharp assignment help from experts.

Free and Open-Source

Python is created under an open source licence that has been accepted by OSI. Because of this, using it is totally free—even for profit. Python can be downloaded and used in applications without costing anything. Additionally, it may be freely changed and distributed again. From the Python website, one can download Python.

Robust Standard Library

Anyone can utilise the vast standard library for Python. In contrast to other programming languages, this implies that programmers don't have to write code for everything. There include libraries for databases, unit testing, expressions, image manipulation, and many more features. A growing number of thousands of components, in addition to the standard library, are all accessible in the Python Package Index.

Note: If you have trouble with programming, take our C++ Programming Help from experts.

Interpreted

Programming languages that are interpreted execute the source code line by line rather than all at once. Because C++ and Java are not interpreted, they must first be compiled in order to be used. Python does not require compilation because the interpreter processes it at runtime.

Portable

The same code can be used on several machines, making Python portable. Let's say you use a Mac to write Python programmes. You don't need to modify it if you subsequently decide to run it on Windows or Linux. As a result, it is not necessary to build software more than once for different platforms.

Object-Oriented and Procedure-Oriented

If a programming language centres design around data and objects rather than functions and logic, it is considered object-oriented. A programming language is instead procedure-oriented if it emphasises functions more than other concepts (code that can be reused). The fact that Python supports both object-oriented and procedure-oriented programming is one of its key strengths.

Pros

Are you interested in what the library has to offer now that we've explained what React is? If so, let's go right to React's advantages and disadvantages.

Virtual DOM

React's performance and quickness are due to the virtual DOM (Document Object Model). It allows developers to quickly produce applications that meet contemporary standards.

The developers of React had the brilliant notion to use the virtual DOM, and it worked like a charm! With virtual DOM, developers may make changes to the app's smallest parts without affecting the whole thing.

A virtual duplicate of the actual DOM is all that a virtual DOM is. Another significant benefit is that it updates faster than a typical DOM.

Top pros and cons of Assembly Language

 Developers and systems employ a variety of computer languages, as you are certainly aware if you work in the software industry. While people use higher-level languages like JavaScript, C++, etc., computers only understand machine-level languages. However, there is a language that sits in the middle and acts as a mediator between these two types of languages, known as assembly language. What is an assembly language, though, and how does it fit into the hierarchy of computer languages?

Note: If you have any problem with your homework, take our assembly language homework help from professionals.

What Is Assembly Language?

A low-level programming language called assembly language, also called assembler language, is used to communicate instructions with particular computer hardware and control the flow of information. It does this by forming short codes out of human-readable mnemonics (such as "LDA" to stand for load accumulator) that make it simpler for the individual trying to do the work. Through the assistance of programmes called assemblers, these brief codes are translated into binary (i.e., 1s and 0s) machine learning language.

Why should you learn Assembly Language?

For programmers, learning assembly language is still crucial. It assists in regaining total command of the system and its resources. The programmer can write code to access registers and get pointers' and values' memory addresses by knowing assembly language. It mostly aids in optimising speed, which raises effectiveness and performance.

Learning assembly language is beneficial for comprehending how the processor and memory work. A comprehensive understanding of the processor is required if the programmer is creating any code that functions as a compiler. Understanding how CPUs and memory operate with the use of assembly language. It speaks in a coded, symbolic manner.

The use of assembly language enables direct hardware communication. This language is mostly focused on computer architecture, and it can identify certain processor types and how they differ for various CPUs. When compared to other high-level languages, assembly language is more transparent. Although it just contains a few actions, it is useful for comprehending algorithms and other control flow. It simplifies the code and facilitates debugging as well.
