Cloud Computing

 World wide web.


What is WWW(World wide web) stand for?


It's a service that provides from the internet and a large collection of electronic documents stored on computer around the world. As I mention above the inventor of www is Tim Berners-Lee in 1989 while working at CERN. On August 6, 1991, the first website was introduced to the world. This invention changed how we get and share informations, learning, business and entertainment. And now it's a key part of our daily lives and it helps to connect people in worldwide. In the world most popular part is www but they provide more useful services to the people like,


  • File transfer protocol(FTP).
  • E-mail.
  • Remote login.
  • Cloud computing.

Cloud computing.

Cloud computing has become a major part of our digital lives, and it offers various services to individuals and businesses. If you're new here, you might need to know some terms like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Let's break down these three models and understand how they differ.

Infrastructure as a Service (IaaS). 

This is like having a virtual computer or a server over the internet. With IaaS, you are able to access computing resources such as storage, networking, and processing power without the need to maintain physical hardware. This model is ideal for businesses that want to scale their infrastructure quickly and efficiently without the hassle of managing servers. 

E.g., iCloud and Google Docs.

Platform as a Service (PaaS).

This service basically helps you to develop software and gives you a good environment to run softwares. You get all the tools you need to create and run software without the headache of managing servers. This is perfect for developers who want to focus on making cool apps without getting stuck in the technical stuff.

E.g.,  Oracle Cloud platform.

Software as a Service (SaaS).

SaaS applications can be accessed through a web browser or a mobile browser. On some platforms, clients typically need to pay a subscription fee to access the software. SaaS is handy among businesses because it offers easy access to software without the need for installation or maintenance, and they can access to the powerful software without buying it themselves.

E.g.,  Microsoft Office 365, Zoom, Netflix, Adobe, etc.

In summary, IaaS provides the infrastructure, PaaS offers the platform for application development, and SaaS delivers software applications to users. Each model has different needs and offers various benefits, like cost savings.

 MACHINE LANGUAGE. What is machine language? In the world right now, we use Artificial intelligence to make our lives easier, but in the past, it’s not been easy like this. Over the years, computer languages have evolved from low-level to high-level languages.In addition, there are 5 main computer generations, and each one has different technologies in their own time. First generation (1940s-1950s) - used vacuum tubes. Second generation (1950s-1960s) - used transistor. Third generation (1960s-1970s) - used Integrated circuit.(IC) Fourth generation (1970s-present) - used Microprocessor. Fifth generation (present and future) - using Artificial intelligence.(AI) Low-level Language. The first generation used low-level languages, also known as machine language. Low level language is the only language that can be understood by the computer, and it contains only two digits 1 & 0. 1 refers to “true” and 0 refers to “false”. 01100011 01101111 01101101 01110000 01110101 0111...

Amplitude Modulation

  Amplitude Modulation Using High-Level Modulation Circuit Introduction Amplitude modulation is a way of sending information like audio or voice through the air using radio waves. Imagine if there is a message you need to send to someone, like your voice message or  music then you need a carrier wave with a high frequency that can travel long distances. A common circuit for implementing amplitude modulation uses a transistor-based configuration known as the high-level modulation circuit. Circuit components  Radio frequency carrier source - generates high frequency carrier signal normally in kHz to MHz range. Radio frequency class c amplifier - a class C amplifier is a electronic amplifier that only works part of the time. Modulating signal - amplifies the low-frequency audio signal.  Modulation transformer - couples the modulated output to the next stage. Power supply - provides the DC (direct current) voltage to the circuit. Other components - Resistors and cap...

  5G Technology And Its Impacts. 5G technology means it's the fifth generation of mobile networks, and this is also the newest wireless standard after the 1 to 4 generation. 5G enables new kinds of improvements over the old 4G network, so let’s talk about its impacts on us. 5G technology delivers higher multi-Gbps data peak speed; in addition, it offers massive network capacity, ultra-low latency, and increased availability to receivers. We can feel new user experience with improved efficiency. Now 5G technology is being expanded very quickly because it empowers new experiences and connects various industries. It can be up to 100 times faster than a 4G connection (average: 10 GB/s), so you can download movies in seconds. In 5G, you can experience low latency while you are working with it. Low latency means a delay; sometimes you had experience that while data transferring. If you are transferring a 1 GB file and your connection is unstable, it will cost you some extra time to...
