It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. When the data transmission can be done in between two or more computers using a communication medium like cables or wires, then it is called as a computer network. So this type of connection is also known as ‘Remote Modem Access’ connection. Once you are connected to the Internet, you can access and view websites using a type of application called a web browser.Just keep in mind that the web browser itself is not the Internet; it only displays websites that are stored on the Internet. From the user's perspective, Wi-Fi is internet access from a wireless-capable device like a phone, tablet, or laptop. The internet is the largest computer network in the world, connecting millions of computers. The main difference between Ethernet and Internet is Ethernet works in the LAN and Internet works in the WAN. According to the American sociologist Earl Robert Babbie, “Research is a systematic inquiry to describe, explain, predict, and control the observed phenomenon. A computer network technology allows institutions & businesses to send data digitally with the help of information systems. So, it is highly insecure. We know that routers & modems in the field of networking play an essential role. Fixed wireless. In dial-up connection to Internet, Host carries all the command that are typed on a client machine and forward them to Internet. The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. Unit VI Internet and Its Applications 3. It’s much faster than cable, way faster than dial-up, and can carry large amounts of data in a single line, often reaching multiple terabits of data transfer fairly easily. Fiber Internet is the latest change to the way data is transferred around the globe. And the host to which the client gets connected is actually connected to the Internet by a full time connection (See Leased Connection). Internet is not secure because almost most of the users from worldwide are connected to the internet and can share anything in this digital world. Internet: The Internet, sometimes called simply "the Net," is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers). Some cable internet services offer slow speeds as a low-cost internet option but are often capable of providing much higher speeds for a higher monthly cost. Types of E-Commerce. There are several types of electronic commerce. Ques. A network is a group of two or more computer systems linked together. There are two main types of computer networks: v Local Area Network (LAN): A LAN is two or more … A careful consideration of study regarding a particular concern or problem using scientific methods. Unit VI Internet and its Applications Introduction – History of the Internet – Understanding WWW – Web Browsers – Favourites and Bookmarks – Kinds of Information available – Parts of Internet – … What is Research: Definition. It's an industry term that represents a type of wireless local area network (LAN) protocol based on the 802.11 IEEE network standard. and Ethernet is secure and the Internet is insecure.
