There are two main types of computer networks: v Local Area Network (LAN): A LAN is two or more … Fiber Internet is the latest change to the way data is transferred around the globe. According to the American sociologist Earl Robert Babbie, “Research is a systematic inquiry to describe, explain, predict, and control the observed phenomenon. So, it is highly insecure. What is Research: Definition. DSL is the most common internet service type with speeds lower than 25 Mbps. 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. It's an industry term that represents a type of wireless local area network (LAN) protocol based on the 802.11 IEEE network standard. 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. We know that routers & modems in the field of networking play an essential role. A network is a group of two or more computer systems linked together. 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. 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. So this type of connection is also known as ‘Remote Modem Access’ connection. The main difference between Ethernet and Internet is Ethernet works in the LAN and Internet works in the WAN. From the user's perspective, Wi-Fi is internet access from a wireless-capable device like a phone, tablet, or laptop. 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. 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. A careful consideration of study regarding a particular concern or problem using scientific methods. And the host to which the client gets connected is actually connected to the Internet by a full time connection (See Leased Connection). 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.
