How Does The Internet Work And How Was It Invented?

Internet is built upon a collection of networks that covers the world. These networks contain differnt types of computers, and somehow, something must hold the whole thing togather. That something is TCP/IP. TCP/IP is the common name of over 100 protocols that are used to connect computers and networks. The actual name TCP/IP comes from TCP ( Transmission Control Protocol) and IP ( Internet Protocol ). Within the Internet, data is broken into small packets called fragments. For example, say that you send a long mail on the other side of the country. TCP will divide the message into packets. Each packet is marked with a sequence number. Each host on the Internet is assigned a unique 32-bit (For IP version 4) IP address. Data are carried out in the form of packets which contain source and destination IP addresses. Internet routers maintain a view of the network topology in the form of routing tables. These tables are consulted when making packet routing decisions. The process of routing involves inspecting the destination address contained in the packet and based on the contents of the routing table, determining the next hop router to which the packet should be relayed. Each router along the source and the destination nodes repeat this process until the packet is finally delivered to the destination host.

Wireless interconnecting in USA

Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. The new discovery, made by researchers at Oregon State University, the University of Iowa and Philipps University in Germany, has identified a way in which nanoscale devices based on gallium arsenide can respond to strong terahertz pulses for an extremely short period, controlling the electrical signal in a semiconductor. The research builds on previous findings for which OSU holds an issued patent.

Updating our Google Account inactivity policy

Every day Google works hard to keep you and your private information safe and secure by preventing unauthorized access to your Google Account with our built-in security protections. And keeping you safe means having strong privacy practices across our products that minimize how long we store your personal files and any data associated with them. We want to protect your private information and prevent any unauthorized access to your account even if you're no longer using our services. Therefore, we are updating the inactivity period for a Google Account to two years across all our products and services. This change starts rolling out today and will apply to any Google Account that's been inactive, meaning it has not been signed into or used within a two-year period. An inactive account and any content in it will be eligible for deletion from December 1, 2023. What this means for you: These changes do not impact you unless you h
