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

In the early days‚ someone probably denounced cable by saying‚ “Television is like water‚ and no one will ever pay for something they can get for free.” Still‚ people subscribed. Cable provided a tremendous service for those who couldn’t receive signals by local affiliates. It rapidly became part of the television landscape. Fifty years later‚ the television world is littered with cable conglomerates that now compete with satellite companies by offering hundreds of digital channels and consumer-friendly

Benefits of Twisted Pair Cable The first change I would suggest would be to setup a client/server network in which all 20 computers are connected to the main the computer. In this case‚ we would add another computer to use as the main workstation and central server so we would actually have 21 computers. We could just connect them all with cat 5 cables since there are only 20 clients but if the company could afford it‚ I would advise them to go with fiber optic cables to reduce noise and interference

TELPHONY 6E 10Gbps GAGBIT ETHERNET/HIG END WORK STATION Exercise 4.1.5 Exercise 4.1.6 Coaxial cable conducts electrical signal using an inner conductor (usually a solid copper‚ stranded copper or copper plated steel wire) surrounded by an insulating layer and all enclosed by a shield‚ typically one to four layers of woven metallic braid and metallic tape. The cable is protected by an outer insulating jacket. Normally‚ the shield is kept at ground potential and a voltage is

cable modem: ABSTRACT Cable modems are devices that allow high-speed access to information at a distant server may it be Internet server or video on demand server‚ via a cable television network. While similar to the traditional (analog) dialup modems‚ a cable modem is significantly more powerful‚ capable of delivering data approximately 500 times faster. During the early to mid - 1990s‚ the two-way interactive communication capability of the existing cable network infrastructure was realized

let’s talk about the wiring (Dean‚ 2010). I would suggest switching from the coaxial cable to an unshielded twisted pair preferably Cat 5. This cable is a very inexpensive alternative and has the capabilities of being used on your existing phone systems as well. As far as speed goes you will be losing a little bit of the transfer speed‚ but it won’t be that noticeable. Cat 5 is much cheaper than the coaxial and it is more flexible. By switching to Cat 5 you will be saving the companies resources

Shielded Twisted- pair: It’s a type of cable that consists of several conducting cores twisted together in pairs surrounded by a shield inside the jacket.

ISDN vs. Cable Modems 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
