Communications _____ define the rules and data formats for exchanging information in a computer network Technologies Protocols Media Web. Coaxial cable is widely used for Cable television systems Office buildings Work-sites for local area networks All of them are true. Interplanetary radio wave is a: Wired technology Wireless technology Exotic technology All of them are false. The next generation of the protocol with a much enlarged addressing capability is IPv4 IPv5 IPv6 IPv7. Network programming is basically: Process programming Socket programming Range programming Virtual programming. Terrestrial microwave is a: Wired technology Wireless technology Exotic technology All of them are false. When all nodes are connected to a special central node is called: Start network Bus network Ring network Mesh network. When each node is connected to its left and right neighbour node, such that all nodes are connected and that each node can reach each other node by traversing nodes left- or rightwards is called: Start network Bus network Ring network Mesh network. Which of these devices is NOT a network hardware component: Interface cards (NICs) Hubs USBs Bridges. A bridge can be: Local Wireless Remote All of them are true. To make a network cable you have to put the wires in the following order, from left to right: White orange, orange, white green, blue, white blue, green, brown, white brown White orange, orange, white green, blue, white blue, green, white brown, brown White orange, orange, white green, white blue, blue, green, white brown, brown Orange, white orange, white green, blue, white blue, green, white brown, brown. Networks may be classified according to a wide variety of characteristics such as: The medium used transport the data Communications protocol used Scale, topology, and organizational scope All of them are true. ________ is a piece of computer hardware designed to allow computers to physically access a networking medium Interface card (NICs) Hubs Switch Bridge. A _______ is an electronic device that receives a signal, cleans it of unnecessary noise, regenerates it, and retransmits it at a higher power level, or to the other side of an obstruction, so that the signal can cover longer distances without degradation Switch Repeater Router Bridge. Coaxial is a: Wired technology Wireless technology Exotic technology All of them are false. _______ is a family of connection less protocols used in LANs RJ45 Infrared Ethernet Internet. A switch is distinct from a _________ in that it only forwards the frames to the ports involved in the communication rather than all ports connected Repeater Router Hub Bridge. In most twisted pair Ethernet configurations, repeaters are required for cable that runs longer than: 10 meters 50 meters 100 meters 150 meters. Switches work on: (REVISAR) Layer 2 of the OSI Model Layer 3 of the OSI Model Layer 4 of the OSI Model Layer 5 of the OSI Model. A _______ is an internet working device that forwards packets between networksby processing information found in the datagram or packet: Switch Repeater Router Bridge. Synchronous Optical NETworking (SONET) and Synchronous Digital Hierarchy (SDH) are standardized multiplexing protocols that transfer multiple digital bit streams over optical fiber using Lasers Waves Bits Packages. WAN is bigger than MAN CAN LAN All of them are true. Computer networks can be classified in: Wired technologies and Wireless technologies Wired protocols and Wireless protocols Only Wired technologies Only Wireless technologies. When each node is connected to an arbitrary number of neighbours in such a way that there is a least one traversal from any node to any other, is called: Start network Bus network Ring network Mesh network. When all nodes are connected to a common medium along this medium, is called: Start network Bus network Ring network Mesh network. ATM is a switching technique for telecommunication networks that: Uses asynchronous time-division multiplexing and encodes data into small, fixed-sized cells Just uses asynchronous time-division multiplexing Just encodes data into small, fixed-sized cells Uses synchronous time-division multiplexing and encodes data into small, fixed-sized cells.
