19. IEEE 802 is: a study of standards of the Institute of Electrical and Electronics Engineers (IEEE), which acts on Computer Networks, and according to its own definition of local area networks (LAN, in English LAN) and networks metropolitan area (MAN in English). The name is also used to refer to IEEE 802 standards proposed, and some of which are well known: Ethernet (IEEE 802.3) or Wi-Fi (IEEE 802.11), Bluetooth is even trying to standardize on the 802.15 (IEEE 802.15 .)
It focuses on defining the lower levels (according to the OSI reference model or any other model), namely subdivides the second level, liaison, in two sublevels, the logical link, included in 802.2, and access medium. The rest of the standards set out both the physical level, as the media access sublayer.
20. is Token Ring: Token Ring network is an architecture developed by IBM in the 1970s with a logical topology and technical ring token passing access. Token Ring is included in the IEEE 802.5 standard. Obsolete by the popularity of Ethernet and now is used in network designs.
The IEEE 802.5
The IEEE 802.5 is a standard by the Institute of Electrical and Electronics Engineers (IEEE), and defines a local area network LAN in ring configuration (Ring), with token-passing method (Token) and medium access control. The speed of its standard is 4 or 16 Mbps
The design of a Token Ring network was attributed to E. E. Newhall in 1969. International Business Machines (IBM) first published its Token Ring topology in March [1982], when the company filed papers for the IEEE 802 project. IBM Token Ring announced a product in 1984 and in 1985 it became a standard ANSI / IEEE.
It is almost identical and fully compatible with the network of IBM token ring. In fact, the IEEE 802.5 specification was modeled after the token ring, and still shading the development. In addition, the IBM token ring specifies a star, with all end stations attached to a device that is called multistation access unit (MSAU). In contrast, IEEE 802.5 does not specify a topology, although virtually all IEEE 802.5 implemented based on a star, and also specifies a type of media, while token ring networks using IBM's information field size routing.
The IEEE 802.5 frame supports two basic types: tokens and command frames and data. The Token is a pattern that circulates around the ring in one direction of movement. When a station wants to transmit and Token passes through it, take it. It can only remain in his possession a certain time (10 ms). Have a length of 3 bytes and consists of a start delimiter, an access control byte and an end delimiter. As for the Frames of commands and data may vary in size depending on the size of the field of information. The data frames have information for higher protocols, while command frames contain control information.
20. which is LAN: A local area network, local network or LAN (local area network of English) is the interconnection of several computers and peripherals. Its extension is physically limited to a building or a neighborhood of 200 meters, or relays could reach a field distance of 1 kilometer. Its wider application is the interconnection of PCs and workstations in offices, factories, etc.
The term local network includes both hardware and software necessary to interconnect the various devices and information processing.
21: it's WAN networks are spread over a large geographic area. Contains a collection of machines dedicated to running user programs (hosts). These are connected by the network that carries messages from one host to another. These host LAN access to the subnet of the WAN by a Reuter. Therefore tend to be point to point networks
The subnet has several elements:
- Lines of communication: Move bits from one machine to another.
- Switching elements: specialized machines that connect two or more transmission lines. Are often called on walkers or Reuters.
Each host is then connected to a LAN which is the treadmill that is responsible for sending the information for the subnet.
A WAN contains numerous wires connected on a pair of walkers. If two walkers who do not share cable wish to communicate, they must do so through at intermediate walkers. The complete packet is received in each of the intermediates and stored there until the required output line is free.
You can set WAN systems or satellite radio ground where each walker is in an antenna that can send and receive information. By their nature, satellite networks will broadcast.
Today the Internet provides high speed WAN, and the need for private networks WAN has been drastically reduced while using VPN encryption and other techniques that network dedicated to continually rise.
Normally the WAN is a peer to peer network, ie packet switched network. WAN networks may use satellite communication systems or radio. It was the advent of laptops and PDAs that brought the concept of wireless networks.
22. which is the Mac: In computer networks the MAC address (English acronym for Media Access Control or media access control) is a 48-bit identifier (hexadecimal six blocks) that uniquely corresponds to an Ethernet network. Also known as the physical address as to identify network devices. It is individual, each device has its own specific MAC address and configured by the IEEE (the last 24 bits) and the manufacturer (the first 24 bits) using the OUI. Most of the protocols that work at Layer 2 of the OSI model using one of three numbering handled by the IEEE: MAC-48, EUI-48 and EUI-64 which have been designed to be globally unique identifiers. Not all communications protocols use MAC addresses, and not all protocols require globally unique identifiers.

38. is WPAN: Wireless Personal Area Networks, Wireless Personal Area Network or Personal Area Network or Personal Area Network is a network of computers for communication between different devices (as computers, internet access points, cell phones, PDAs, devices audio, printers) near the access point. These networks are usually a few meters and personal use as well as outside it.
39. is runnig Wi-Fi (pronounced in Spanish / wɪfɪ / and English / waɪfaɪ /) is a trademark of the Wi-Fi Alliance (formerly WECA: Wireless Ethernet Compatibility Alliance), the trade organization that adopts this test and certify teams to meet standards related to 802.11 wireless local area networks.
40. that is TCP / IP: Transmission Control Protocol (Spanish Transmission Control Protocol) or TCP is one of fundamental Internet protocols. It was created between 1973 and 1974 by Vint Cerf and Robert Kahn.
Many programs within a data network comprised of computers can use TCP to establish connections between them through which can send a data flow. The protocol guarantees that data will be delivered to its destination without errors and in the same order they were transmitted. It also provides a mechanism for distinguishing different applications within a single machine, through the concept of port.
TCP supports many of the most popular Internet applications, including HTTP, SMTP, SSH and FTP.

In multimode fiber optic cables.
ANSI/TIA/EIA-598 describes the color coding system used
47. which describes ANSI/TIA/EIA-598 color coding system used in fiber optic cables large (up to a couple dozen of fibers).
48: it is multimode: Optical fiber is a medium of transmission commonly used in data networks, a very fine line of transparent material, glass or plastics, which sent pulses of light representing the data to transmit. The light beam is completely confined and is spread through the fiber core at an angle of reflection above the critical angle of total reflection, according to Snell's law. The light source may be laser or LED.
The fibers are widely used in telecommunications, as they allow large amounts of data sent at a great distance, with speeds similar to radio or cable. They are the ultimate means of transmission to be immune to electromagnetic interference, are also used for local networks, where they need to take advantage of fiber optics over other means of transmission.
49. which is single mode:
Fiber is classified according to their type of construction and method of propagation of light rays, in addition to their transmission capacity (bandwidth) and easy to attach to the rig connections.
 
A single-mode fiber is an optical fiber in which only one mode of light propagates. Is achieved by reducing the diameter of fiber core to a size (8.3 to 10 microns) that allows only one mode of propagation, it is transmitted straight. The distance ranges from 2.3 km to 100 km up and use center with high-intensity laser cannon. Unlike multimode fiber, singlemode fiber can reach great distances and transmit high bit rates.
Mono-mode fiber uses a simpler system. It only allows one mode of propagation. A single beam of direct light and more intense, and therefore more bandwidth and greater distances.
