What is TCP/IP?

TCP/IP: Transmission Control Protocol/Internet Protocol

TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a set of protocols or rules and procedures that governs communications among computers on the internet. Although the entire internet protocol suite is commonly known as TCP/IP, it is one of the core protocols of the Internet Protocol Suite. It was developed in 1978 and driven by Vint Cerf and Bob Kahn.

TCP/IP is a commonly used standard for transmitting data over networks. In simple words, it is the suite of communication protocols which connect network devices on the internet or used to interconnect network devices on the internet. It decides how the data will be exchanged over the internet through end-to-end communications that include how the data should be arranged into packets (bundles of information), addressed, sent, and received at the destination. This communication protocol can also be used to interconnect network devices in a private network such an intranet or an extranet.

How TCP/IP works?

As the name suggests, TCP/IP comprises two basic protocols: TCP (transmission control protocol) and IP (Internet protocol).

TCP: The TCP allows applications to create channels of communications across a network. It also allows a message to be divided into smaller packets before they are transmitted over the internet and then assembled in the right manner at the destination address. So, it ensures the reliable transmission of data across the network. Furthermore, it also checks errors in the packets and requests for re-transmission if errors are found.

IP: The IP address tells the packets the address and route so that they reach the right destination. It has a method that enables gateway computers on the internet-connected network forward the message after checking the IPS address. It is like a line of workers passing coal from a mine to a mining cart.TCP/IP model layers:

TCP/IP, which is a standard layered protocol suite comprises a set of rules and procedures, is divided into four layers, on the basis of their functionality. Each layer has a specific protocol.

The application layer: This layer includes all the protocols required to communicate directly with the end-users. Some important protocols in this layer include HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol), and the DHCP (Dynamic Host Configuration Protocol).
The transport layer: This layer ensures the transmission of the correct message or data in proper order. It utilizes UDP (User Datagram Protocol) and TCP.
The network access layer: It offers the functionalities to build and handle packets of information.
The internet layer: It performs two basic functions, routing and addressing by using IP (Internet Protocol). It tells how the packets are to be sent to the destination.

What is PHP?

PHP is an open-source, server-side programming language that can be used to create websites, applications, customer relationship management systems and more. It is a widely-used general-purpose language that can be embedded into HTML . This functionality with HTML means that the PHP language has remained popular with developers as it helps to simplify HTML code. What does PHP stand for? PHP stands for ‘PHP: Hypertext Preprocessor’, with the original PHP within this standing for ‘Personal Home Page’. The acronym has changed as the language developed since its launch in 1994 to more accurately reflect its nature. Since its release, there have been 8 versions of PHP, as of 2022, with version 8.1 currently a popular choice among those using the language on their websites. What is PHP used for? PHP programming can be used to create most things that a software developer needs. However, there are three main areas in which it thrives. Server-side scripting Server-side Script is PHP’s main

"5G Technology: What It Is and What It Means for the Future of Connectivity"

5G technology is the latest breakthrough in wireless network technology, promising faster speeds, lower latency, and greater capacity than ever before. It is set to revolutionize the way we connect and communicate, enabling the seamless integration of devices and data into our daily lives. So what exactly is 5G technology? In simple terms, 5G is the fifth generation of wireless network technology. It is designed to operate on a higher frequency spectrum than its predecessors, which allows it to transmit more data at faster speeds with lower latency. 5G technology is expected to be up to 100 times faster than current 4G technology, enabling lightning-fast downloads, smooth streaming, and responsive gaming. The advantages of 5G technology extend beyond just faster speeds. The lower latency of 5G technology means that devices can communicate with each other almost instantly, which is essential for applications such as autonomous vehicles or remote surgery. 5G technology also has the pot

What Is a Database?

Before we learn about a database, let us understand – What is Data? In simple words, data can be facts related to any object in consideration. For example, your name, age, height, weight, etc. are some data related to you. A picture, image, file, pdf, etc. can also be considered data. What is Database? A database is a systematic collection of data. They support electronic storage and manipulation of data. Databases make data management easy. Let us discuss a database example: An online telephone directory uses a database to store data of people, phone numbers, and other contact details. Your electricity service provider uses a database to manage billing, client-related issues, handle fault data, etc. Let us also consider Facebook. It needs to store, manipulate, and present data related to members, their friends, member activities, messages, advertisements, and a lot more. We can provide a countless number of examples for the usage of databases. Types of Databases Here are some popula
