This may include Bluetooth enabled devices or infra-red enabled devices. Dear Readers, Welcome to Computer Network multiple choice questions and answers with explanation. The following image shows both types of cable. This cable contains only two pairs (4 wires). In the UTP (Unshielded twisted-pair) cable, all pairs are wrapped in a single plastic sheath. The twisted-pair cable was primarily developed for computer networks. A single-core coaxial cable uses a single central metal (usually copper) conductor, while a multi-core coaxial cable uses multiple thin strands of metal wires. The larger the AWG size, the smaller the diameter of the core wire. This cable uses an LED as the light source and transmits 850 or 1300 nano-meter wavelengths of light. The following image shows both types of twisted-pair cable. Each pair has one solid color and one stripped color wire. It is used to measure the size of the core. 09910182087 9818558059. Server : A computer that facilities the sharing of data, software and hardware resources on the network. ... With fiber optic backbone across its networks and state-of-the-art distribution set ups, … Interactive multicast implies that TV programs are sent only over transmitters where there are viewers and that only the most popular programs are … There are no servers in peer networks. This is the outer layer of the coaxial cable. The distribution of bandwidth between different subbands is illustrated in FIG. Be it enacted by Parliament in … However, it is obvious that if there are too many simultaneous users, the flow is insufficient. Since the STP cable contains more materials, it is more expensive than the UTP cable. The weakness of this technique is that the frequency multiplexing is not the best use of bandwidth and does not really allow the integration of different services transiting the CATV. The maximum segment length for both cables is 100 meters or 328 feet. The following standards have been proposed as access techniques to allow users time multiplexing on a common band: • MCNS-DOCSIS (Multimedia Cable Network System-Data Over Cable Service Interoperability Specification), used primarily in North America but adopted by some European cable operators. The TIA/EIA specifies standards for the twisted-pair cable. Another solution to obtain a broadband distribution network is to use the wiring of cable operators, when it exists. It can be used both for telephone speech and Internet connections. This cable is thinner, easier to handle and install than the RG-8 cable. LAN Cable: Local Area Network(LAN) cable is also called as Ethernet or data cable. PAN may include wireless computer keyboard and mouse, Bluetooth enabled headphones, wireless printers and TV remotes. "basic service tier" means a package of free-to-air channels provided by a cable operator, for a single price to the subscribers of the area in which his cable television network is providing service and such channels are receivable for viewing by the subscribers on the receiver set of a type existing immediately before the commencement of the Cable Television Networks (Regulation) Amendment Act, 2002 … 2. Because it is of high bandwidth, and consequence high data rate, First standards were released in 1991, known as TIA/EIA 568. 729 (E) – In exercise of the powers conferred by sub-section (1) of section 22 of the Cable Television Networks (Regulation) Ordinance, 1994 (Ordinance No.9 of 1994) the Central Government makes the following Rules namely: 1. Use these shapes for drawing CATV system design floor plans, network topology diagrams, wiring diagrams and cabling layout schemes in the ConceptDraw PRO diagramming and vector drawing software. This shield is built from the same metal that is used to build the core. It reflects light from one endpoint to another. mail us ComputerNetworkingNotes@gmail.com. This cable contains a conductor, insulator, braiding, and sheath. This cable was used to connect a system with the backbone-cable. The Best Live TV Streaming Services for 2021. • IEEE 802.14, which uses ATM technology. In the next part of this article, we will understand the types of connectors that are used to connect cables with networking devices. Fiber Optics. Information on the act, its objectives, short title and commencement is given. The jacket protects the cable from physical damage. CHAPTER II . IP Address : … This cable carries multiple beams of light. About us; Careers; News; Investors; Locate DEN; MY ACCOUNT. They are still used even their use in computer networks has been completely discontinued. Features:  It transmits data only in one direction. Network cables are the transmission media to transfer data from one device to another. Used in the earliest computer networks. This tutorial explains the types of network cables used in computer networks in detail. Networking Tutorials Since both the core and the braided-shield use the same metal, without this layer, they will touch each other and create a short-circuit in the wire. From these specifications, only a few were used in computer networks. Types of Computer Network with computer network tutorial, introduction, features, types of computer network, components, cables and connectors, Router, Intranet, Modem, Uses Of Computer Network, Hub, Software and Hardware, Security, Client/Server network, Disadvantages, Advantages, LAN, PAN, MAN, WAN etc. REGULATION OF CABLE TELEVISION NETWORK. CHAPTER I . Because of multiple beams, this cable carries much more data than the SMF cable. Coaxial cables have been in use for the last four decades. The STP provides more noise and EMI resistant than the UTP cable. THE CABLE TELEVISION NETWORKS (REGULATION) ACT, 1995 . Regulation Of Cable Television Network: 3: Cable television network not to be operated except after registration: 4: Registration as cable operator: 5: Programme code: 6: Advertisement code: 7: Maintenance of register: 8: ... An Act to regulate the operation of cable television networks in the country and for matters connected therewith or incidental thereto. At the beginning of computer networking, when there were no dedicated media cables available for computer networks, network administrators began using coaxial cables to build computer networks. In each and every corner of the country people talk about it. • IEEE 802.14, which uses ATM technology. For example, Piconet is Bluetooth-enabled Personal Area Network which may contain up to 8 devices connecte… In Cable TV networks coaxial cables are used. They were in use even before computer networks came into existence. Back to Gazette Notification. Get detailed information about the Cable Television Networks (Regulation) Amendment Act, 2011 which includes amendments in sections 2, 3, 4 and 4A of the Cable Television Networks (Regulation) Act, 1995. The core is wrapped in the cladding; the cladding is wrapped in the buffer, and the buffer is wrapped in the jacket. The vector stencils library "Cable TV" is included in the Electric and Telecom Plans solution from the Building … Network Interface Unit (NIU) : A Network interface unit is an interpreter that helps in establishing communication between the server and the client. Coaxial cables are no longer used to build any type of computer network. This type of modem requires a determined frequency corresponding to the selected sub-band for the Internet connection. Every two wires are twisted around each other to form pair. The 550-750 MHz band from the headend to serve the user terminal. The following table lists them. In the STP (Shielded twisted-pair) cable, each pair is wrapped with an additional metal shield, then all pairs are wrapped in a single outer plastic sheath. Network Cable Types and Specifications, We do not accept any kind of Guest Post. Coaxial Cable – Write Short Note on Coaxial Cable. Based on conductor a coaxial cable can be categorized into two types; single-core coaxial cable and multi-core coaxial cable. Cladding reflects light back to the core. Be it enacted by Parliament in the Forty … INTRODUCTION Cable Television is the talk of the day. Coaxial cable mainly uses radio frequencies in transmission. The band of 50-550 MHz is reserved for analogue TV channels. The TIA/EIA 568 divides the twisted-pair cable into several categories. This cable consists of color-coded pairs of insulated copper wires. It can be used both for telephone speech and Internet connections. It also uses a fire-resistant plastic sheath.
