Programming is a way of giving a set of instructions to a computer to perform a task. There are already thousands of programming languages in the market like C, C++, JAVA, Javascript, Python, etc. But why there are many programming languages. Can't we just use one programming language for coding everything? Why so many Programming Languages Are Created? The reason behind many programming languages in the market is their requirement per the need. Let's say If you want to cut an apple you will use a knife right and to sew clothes you will use a sewing needle. To do different tasks you use different tools suitable to complete that task. You can't cut an apple using a sewing needle and can't sew clothes using a knife. Same as you can't create all the computer programs using a single programming language as all programming languages are designed for different tasks. For example: To design a Website Frontend HTML, CSS, and JavaScript are used. JavaScript can also be used ...

Programming language is a computer language written to communicate and give instruction to a computer. There are many programming languages for computers. Every programming language has its own features. 5 Types Of Programming Languages Procedural Programming Language Procedural Programming language is a programming language where programs are coded and executed step-by-step as written in code. For example: BASIC, C, Java, etc. Scripting Programming Language Scripting Programming Language is a language whose code can be executed without compilation.

Whenever we enter the URL on the web browser of any website, the website page which is also known as the webpage is loaded. But, how? How the page stored somewhere else load in the user's computer? How Does Website Work? How Does Website Work? There work 2 computers to make the website work. They are Client-side computers and Server-side computers. Client means the User computer and the Server means where the website data, information, and codes are stored. The wifi/network connection and ISP help to exchange information between the Client and Server. When a user/client enters the URL, the request of the URL goes to the Server. When the server gets the request, it checks its database and analyzes if the user is new, or the user already exists on our server, does this user has uploaded anything to our website, etc. information to show the response to the user. Then, the codes run and create suitable data and information for the user, and then the information is converted into an HTM...

ROM is a non-volatile primary storage device that is used to store data permanently. It stands for Read Only Memory. It is non-volatile because the data stored in ROM remain there even after no power supply. ROM is usually used to store firmware. If you have ever installed Operating System, then you might know about BIOS. Software like BIOS is called firmware. This software is installed on ROM to give control of hardware to the user. You can find ROM on many devices like smartphones, laptops, desktop computers, cameras, tablets, etc. Types Of ROM(Read Only Memory) There are usually three types of ROM. They are: PROM, EPROM, and EEPROM. PROM(Programmable Read Only Memory) PROM stands for Programmable Read Only Memory. In PROM, once the program is programmed and stored, it can't be changed. For example: BIOS software. EPROM(Erasable Programmable Read Only Memory) EPROM stands for Erasable Programmable Read Only Memory. In EPROM, reprogramming is possible. But to erase the data from E...

Technology has changed a lot of things in the education field. Before there was a pen and a paper and now there is a computer installed with software to do pen/paperwork.
