Introduction Coaxial cable: is an electrical cable consisting of a round conducting wire, surrounded by an insulating spacer, surrounded by a cylindrical conducting sheath, usually surrounded by a final insulating layer. It is used as a high-frequency transmission line to carry a high-frequency or broadband signal. Sometimes DC power (called bias) is added to the signal to supply the equipment at the other end, as in direct broadcast satellite receivers. Because the electromagnetic field carrying
Computer Network is normally known as a system of interconnected computers & communication devices that can communicate with one another and share resources. At the most elementary level computer consist of two computers connected with each other by a cable to allow them to share data .A device connected to a network is called a node. A node may be a device such as a computer, a printer, workstation etc. When we are talking about computing network we need to know about history of computer network. Early

Introduction Television broadcasts thousands of programs throughout India. Globally India is the third largest in TV viewership, second to China and the United States of America. Disseminating a lot of information, TV influences individuals’ beliefs and opinions. Being a visible medium, its impact transcended the social and academic background of its viewers in India, better-known for its numerous cultures. TV dominates Print and other Electronic Media. Media consumption habits of city dwellers in
Effects on Data Transmitted through Cable Abstract Attenuation refers to any reduction in the strength of a signal. Attenuation occurs with digital or analog signals. Attenuation is the end result of signals being transmitted extended distances. Attenuation is usually expressed in units called decibels (dBs). The cable type will determine at what point along the length of the cable signal degradation occurs. Repeaters can be inserted along the length of the cable to boost the signal strength which
The History Of Cable Television The 1940's and 1950s Cable Television originated in 1948 as a service to households in mountainous or geographically remote areas where reception of over the air television signals was poor. Antennas were erected on mountaintops or other high points, and homes were wired and connected to these towers to receive the broadcast signals. By 1950, 70 cable systems served 14,000 subscribers nationwide. In late 1950s, when cable operators began to take advantage of
seem unfamiliar to us, we take for granted this value that comes only from local businesses. The friendly service and close relationships is only one of the many benefits of buying services from a local provider. Buying services such as Internet, Cable TV, cellular and telephone from a local provider will guarantee remarkable customer service. Since these local businesses are run by people from the community who genuinely care about the community and the people living in it. Local corporate offices
transmission on Internet: DSL, cable, wireless (wireless), and fiber optics. DSL is an existing copper wire of a phone line to deliver high speed internet access. Cable is to utilize a coaxial cable that connects to a television set. WIFI represents wireless that are used for Internet connection without wire. Fiber optic offers many advantages over conventional copper cable lines. It is able to transmit data much faster over greater distances and because the cable is smaller in diameter and weighs
two years since that report and things have only gotten worse for broadcast media. In fact, according to a lot of new data from a variety of sources, the days of broadcasters seem to be numbered. The graph above illustrates the continued drop in cable-TV subscribers (source: ISI Group / Business Insider), which for the first time may drop below 40m. The question to ask is, “Why?” Are people watching less video? According to Cisco, that is far from the case. The growth of data Cisco’s annual Internet
First Amendment Status of Cable TV v. Broadcast Electronic media content can be viewed differently according to personal opinions, but the First Amendment Rights of the United States Constitution lay the foundation for the legal system that is to be followed. These rights form a guide that help citizens have a stronger grasp on what is and isn’t acceptable within the eye of the law. Narrowing down to electronic media content, there has been a rise of tension involving first amendment rights of content
the decision of what type of cable to be used is also decided. When broken down to its simplest form, all types of cabling provide a medium across which network information can travel. The most popular types of network cabling in use today are Twisted-pair (TP) in both unshielded (UTP), and shielded (STP) varieties, and Fiber-optic cable. While the use of Coaxial cable has declined in the arena of Local Area Networking (LAN), it is still prominently featured by Cable Television firms, providing
ISDN VS. Cable Modem 1.0 Introduction The Internet is a network of networks that interconnects computers around the world, supporting both business and residential users. In 1994, a multimedia Internet application known as the World Wide Web became popular. The higher bandwidth needs of this application have highlighted the limited Internet access speeds available to residential users. Even at 28.8 Kilobits per second (Kbps)—the fastest residential access commonly available at the time of this
the receiver of a message or information. Generally, transmission media in computer communications are divided into two categories i.e. bounded and unbounded media. Bounded media are the physical pathways for broadcast information like fiber optic cable while unbounded media is transmission through air like cell phone signals. The bounded media is also known as wired media because it involves physical links while unbounded media is also known as wireless media. Notably, the quality and characteristics
able to see every other node. A bus topology was one of the first topologies used in that it consists of a single bus (aka: backbone). Typically this is a coaxial cable where nodes can connect via a T' connector which allows the bus to continue to the end of the cable. Due to the nature of this design when the data reaches the end of the cable if it's not properly terminated (which kills the signal) then we can receive what's called bounce back. This ricocheting of the data could severely hinder
but if there was a cable going around the mountain signal will not be lost at all, it will just carry on. The first cable I will talk about is the twisted pair type of media. This is mainly used for Ethernet and telephone networking, so this type of cable would be used inside a LAN mostly. The advantages of this cable would be that it can also be used for Telephone service which means that when you dial someone the pulses of electrical charges will be pulsating through the cable through different
Interactive Cable Archives and Videoconferencing The integration of technology into curriculum and instructional practices in P-12 education has been gaining momentum in classroom reform across the nation (Mowre-Popiel, Pollard, & Pollard, 1994). Interactive and digital technologies are now recognized as tools by which educators can bring unique resources into the classroom (Schutte, 1998; Wise, 2002) and engage students in dynamic, self-constructed learning (Branzburg, 2001). The use of technology
The Combining of Cable TV and the Internet The Telecommunications Act of 1996 opened the way for cable TV (CATV) companies to become full-fledged telecommunications companies, offering two-way voice and data communications services, in addition to television programming. After passage of the Act, the cable companies were eager to expand into the new fields of business that had been opened to them, especially the rapidly growing Internet Service Provider (ISP) business. The biggest hurdle facing
