What is Internet & How It Woks

The internet is a global network of computers and other devices that are connected to each other.It allows people from all over the world to share information communicate and access online services.

At a high level the internet works by transmitting data packets between devices over a series of interconnected networks.These networks are made up of a variety of different components including routers switches and servers.

When you send a message or request a webpage your device sends data packets to the network which then forwards them to the appropriate destination.Along the way the data packets may pass through multiple networks each of which helps to route the packets to their final destination.

The internet relies on a set of standardized protocols such as TCP/IP HTTP and DNS which help to ensure that data packets are transmitted and received correctly.These protocols provide a set of rules that govern how devices communicate with each other over the internet.

TCP/IP HTTP and DNS are all protocols used in computer networking.

TCP/IP(Transmission Control Protocol/Internet Protocol) is a suite of protocols used for communication over the internet.It characterizes how data is transmitted between gadgets connected with the internet and it ensures that the data is delivered accurately and dependably.

HTTP (Hypertext Transfer Protocol) is a protocol used for transferring data over the World Wide Web. It characterizes how internet browsers and web servers communicate with each other to exchange information for example web pages and multimedia content.

DNS (Domain Name System) is a protocol used for translating domain names into IP addresses.It enables users to access websites using human-readable domain names(www.example.com) rather than IP addresses which are difficult for people to remember.DNS servers maintain a database of domain name to IP address mappings and they respond to queries from clients to resolve domain names to their corresponding IP addresses.

IPS & AMOLED DISPLAY || PROS & CONS || BETTER DISPLAY

AMOLED and IPS are two different types of display technologies used in modern smartphone televisions and other electronic devices.In this article we will discuss the technical details and characteristics of each technology as well as their pros and cons. IPS (In-Plane Switching) and AMOLED (Active-Matrix Organic Light-Emitting Diode) are two different types of display technologies used in modern smartphones and other electronic devices. Here are some differences between IPS and AMOLED Display quality : AMOLED displays typically offer more vivid colors and deeper blacks than IPS displays due to their ability to turn off individual pixels to create true blacks. Power consumption : AMOLED displays are more power-efficient than IPS displays especially when displaying black or dark colors because they do not require a backlight to operate. Viewing angles : IPS displays generally offer better viewing angles than AMOLED displays which can appear washed out when viewed from an angl...

What is the use of Band in Wi-Fi & Major role of Bands

Wi-Fi is a technology that allows devices to connect wirelessly to the internet or a local network. It uses radio waves to transmit data between devices eliminating the need for physical cables. Wi-Fi technology is based on a set of standards developed by the Institute of Electrical and Electronics Engineers (IEEE) called 802.11 .These standards define the technical specifications for wireless local area networks (WLANs). To use Wi-Fi you need a Wi-Fi-enabled device like a smartphone laptop or tablet, and a wireless router or access point.The router or access point connects to the internet or a local network using a wired connection, and then broadcasts the wireless signal to Wi-Fi-enabled devices in the area. When a device connects to a Wi-Fi network it is assigned an IP address which allows it to communicate with other devices on the network and access the internet.Wi-Fi networks can be secured with a password or other authentication methods to prevent unauthorized access. Wi-...

What does "nm" mean for Processor || Importance of Processor || What is 4 nm Processor

NM (nanometer) is a term used to describe the size of the transistors that make up the processor.The smaller the size the more transistors can fit into the same area and the more powerful and energy-efficient the processor can be. For example a 7nm processor has transistors that are 7 nanometers in size whereas a 14nm processor has transistors that are 14 nanometers in size.The smaller size of the 7nm transistors allows more of them to be packed onto the processor resulting in better performance and lower power consumption compared to a processor with larger transistors. The importance of the size of transistors in a processor lies in the fact that it directly affects the performance and power efficiency of the processor.As the size of the transistors gets smaller the processor can perform more calculations per clock cycle which increases its overall speed and efficiency.Additionally smaller transistors require less power to switch on and of which reduces the power consumption and...
