MSOs are multiple system operators. These are defined as an operator of multiple cable television systems. This usually refers to large cable companies that provide service for multiple communities, such as Time Warner Cable, ComCast or Cox Cable and similar
Since the introduction of data pagers, voice pagers have also emerged. These types of pagers use a voice network to transmit a short audio message that the user can then retrieve. VOIP Phones – VOIP (Voice over Internet Protocol) is a technology that can transmit audio messages over an internet protocol. The name voice would probably throw most people off, but since VOIP is transferred over an internet protocol it thereby uses data networks. Skype/FaceTime – Both Skype and FaceTime utilizes video telephony and VOIP technologies.

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.

1. What is the Internet? The Internet is a globally interconnected network of computers that, operating via several specific protocols, serves as a worldwide information system and provides the technological infrastructure on which countless applications are run (Leiner et al., 2012; Woods, 2013a). At the hub of every network is a server, with the Internet essentially being formed through the connection of multiple servers, encompassing all connected computers and creating a larger ‘inter-network’ (Woods, 2013b). 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).
The Windows 7 command-line utility that can tell you if the TCP/IP stack of another system on the network is functioning normally is called __________________. Ping.exe 7. The Windows 7 command-line utility that enables you to generate DNS request messages and then transmit them to specific DNS servers on the network is called __________________. Nslookup.exe 8. Most networks use __________________ to dynamically assign addresses and configure computers to use them.
An ILEC (incumbent local exchange carrier) is a telephone company that provided local service prior to the Telecommunications Act of 1996 which owns most of the local loops and facilities in a serving area. In the U.S., the Regional Bell Operation Companies (RBOCs) that were formed after the divestiture of AT&T and the Independent Operating Companies (IOCs) that is usually located in more rural areas or single cities. CLEC (Competitive Local Exchange Carrier) is a company that builds and operates communication networks in areas and provides its customers with an alternative to the local telephone company within the existing ILEC’s territory. The term distinguishes new or potential competitors from established local exchange carriers (local exchange carrier) and arises from the Telecommunications Act of 1996, which was intended to promote competition between both long-distance and local phone service providers, to compete with the incumbent Regional Bell Operation Companies (RBOC). MSO (Multiple System Operator) is the industry term for "Cable Company.” Each cable
Comcast also has worries about retransmission fees as a broadband provider, and a content provider. Even though the company has challenges the company has been able to grow its moderating cable distribution and cable network business. At the same time Comcast is trying to reinvent a broadcasting business that is declining. Comcast has expanded its business to invest in General Electric’s NBCU. Comcast is looking at five areas to pursue new strategies.
Unit 1 IP Addresses Classes and Special-Use IP Address Space Network IDs used to be divided into classes, and these classes are Class A, B, and C. These classes were allowed to have a range of addresses depending subnet we are using. This class-based system would work well for a while, but with the rapid growth of the Internet it became evident that this addressing scheme had to be changed in order to support the many networks that were being created (CompTIA Network, Ch.7, 2009). This 32-bit IP addressing system is subdivided into two portions: the network address space and the host address space in IPv4. Class A were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero. The first octet (the left-most eight bits) is used to define the network ID.

These classes were allowed to have a range of addresses. This class-based system would work well for a while, but the rapid growth of the Internet it becomes evident that this addressing scheme had to be changed in order to support the many networks that were being created. A class full system would be created and still used the IP addressing fundament of a classless system. This 32-bit IP addressing system is subdivided into two portions; the network address space are the host address space. Class A addresses were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero.
