B) Routing An IP network that is formatted such as 192.168.1.0/25 is referred to as what type of notation? A) CIDR notation. What is the default network protocol of the Internet and most modern corporate networks? D) TCP/IP What was used by TCP/IP networks to perform name resolution prior to the introduction of the Domain Name System? A) Hosts files.
Application layer address, network layer address, and data link layer address. Application layer address are does such as the ones used to identify websites, (www.yahoo.com). This is easier to remember that the actual IP address it represents. When a user types in the web address the request is then passed to the network layer using HTTP. The network layer then uses its protocol (IP) and translates that www.yahoo.com into an IP address.

UNIT 33: THE IMPACT OF COMMUNICATIONS TECHNOLOGY ON BUSINESS Describe how the internet operates 1. What is the internet? When and how did it start? 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 they get information from any other computer (and sometimes talk directly to users at other computers). the 1960s and 1970s, the US Department of Defense funded programs where computer scientists were paid to develop Internet protocols.
Each device on the network has a unique numerical address and the Internet uses the DNS (Domain Name System) to allocate each a corresponding human-readable address (Woods, 2013a). Information is requested from a server and is sent using the packet switching and TCP/IP (Transmission Control Protocol/Internet Protocol) system (Jamison, 2001; Woods, 2013b). This involves breaking large files into smaller ‘packets’, allocating each packet addressing information, and sending them via different routes to be reassembled – including verification – at their destination (Jamison, 2001). Constantly evolving, the Internet has become an all-encompassing social, communicative and collaborative tool that is arguably essential to modern life (Leiner et al., 2012). 2.
Privacy is defined as the freedom from being observed or disturbed by others. For those born after 2000 BC, this definition makes no sense. Nowadays, more than 3 billion people worldwide are connected to each other through the internet, and they share their daily life with family, friends, foreigners, and even criminals! Technology is developing rapidly; it can be found almost everywhere with user friendly functionality, but are we aware of how technology is overrunning our privacy life? There are many technologies that strongly interfere with our privacy, yet three are the major ones: cellphones, scanning, and surveillance cameras.
