The Bits and Bytes of Computer Networking Questions and Answers Rated A TCP/IP Five Layer Model ✔✔Physical layer , Data link Layer, network Layer, Transport Layer, Application Layer OSI Model... (7 layers) ✔✔The seven layers Physical, Data link Layer, Network layer, Transport Layer, Session Layer, Presentation Layer, Application Layer Internetwork ✔✔The loose collection of networks called "the Internet" is the short form of which of the following words? a. internetwork c. interarpanet b. internexus d. interconnect Protocal (Network) ✔✔code of correct conduct Defined set of standards that computers must follow in order to communicate properly Computer Networking ✔✔The sharing of information or services between computers using wireless or cable transmission media Physical Layer (Layer 1) ✔✔Represents the physical devices that interconnect computers. Specifies how signals are sent over connections. Data Link Layer (Layer 2) ✔✔The second layer in the OSI model and TCPIP Model. This layer bridges the networking media with the Network layer. Its primary function is to divide the data it receives from the Network layer into frames that can then be transmitted by the Physical layer. Network Layer (Layer 3) ✔✔-responsible for adding routing and addressing info to the data -accepts the segment from the transport layer and adds info, creating a packet (includes source/destination IP) -responsible for providing routing/delivery info, but not guaranteed delivery -manages error detection and node data traffic (i.e, traffic control) Client ✔✔A computer that requests data stored on a server. Server ✔✔A computer that awaits and responds to requests for data. Transport Layer ✔✔The fourth layer of the OSI model. In this layer protocols ensure that data are transferred from point A to point B reliably and without errors. this layer services include flow control, acknowledgment, error correction, segmentation, reassembly, and sequencing. Session Layer (Layer 5) ✔✔OSI Layer: Responsible for managing and controlling the synchronization of data between applications. Performs connections between apps. Presentation Layer (Layer 6) ✔✔OSI Layer: Converts data intended for or received from the application layer into other formats. For example graphics, text, and sound/video data. Also handles encryption. Application Layer ✔✔The seventh layer of the OSI model. Fifth Layer of the TCP Model. Application layer protocols enable software programs to negotiate formatting, procedural, security, synchronization, and other requirements with the network. Cat5 cable Category 5 ✔✔- Networking twisted pair cabling standard used to support 100 Mbps and 2 Gbps Ethernet connection speeds. CAT5e Category 5e ✔✔- Networking twisted pair cabling standard used to support 100 Mbps and 2 Gbps Ethernet connection speeds. - Provides additional protection from EMI. Replaced CAT5 CAT6 (category 6) ✔✔Twisted-pair cables capable of carrying up to 1000Mbps (1 gigabit) of data up to a length of 100 meters Crosstalk ✔✔occurs when the signals of one wire affect the signals on an adjacent wire Copper cable ✔✔Characteristic features of Category 5 (CAT5) cabling. RJ-45 connector 100 Mbps Ethernet fiber-optic cable ✔✔Cable that uses light guided through thin glass tubes, instead of electrical signals, to transmit data. It is very fast but also expensive. hub ✔✔A device that uses its ports to connect de [Show More]
