kobe bryant


Kobe Bean Bryant (born August 23, 1978(1978-08-23)), frequently referred to simply as Kobe, is an American All-Star shooting guard who plays for the Los Angeles Lakers in the National Basketball Association (NBA). Bryant enjoyed a successful high school basketball career and made instant headlines when he decided to go directly into the NBA upon graduation. Bryant and then-teammate Shaquille O'Neal led the Lakers to three consecutive NBA championships from 2000 to 2002. After O'Neal's departure following the 2003–04 season, Bryant became the cornerstone of the Lakers franchise. He led the NBA in scoring during the 2005–06 and 2006–07 seasons. In 2006, Bryant scored a career high 81 points against the Toronto Raptors, the second highest number of points scored in a single game in NBA history, second only to Wilt Chamberlain's 100 point performance.

optic fiber


An optical fiber (or fibre) is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss,

inranet

An intranet is a private computer network that uses Internet technologies to securely share any part of an organization's information or operational systems with its employees. Sometimes the term refers only to the organization's internal website, but often it is a more extensive part of the organization's computer infrastructure and private websites are an important component and focal point of internal communication and collaboration.

network hub


A network hub or repeater hub is a device for connecting multiple twisted pair or fibercoptictEthernet devices together and thus making them act as a single network segment.

hdtv


High-definition television (or HDTV) is a digital television broadcasting system with higher resolution than traditional television systems (standard-definition TV, or SDTV). HDTV is digitally broadcast; the earliest implementations used analog broadcasting, but today digital television (DTV) signals are used, requiring less bandwidth due to digital video compression.

ip protocol

The Internet Protocol (IP) is a protocol used for communicating data across a packet-switched internetwork using the Internet Protocol Suite, also referred to as TCP/IP.
IP is the primary protocol in the Internet Layer of the Internet Protocol Suite and has the task of delivering distinguished protocol datagrams (packets) from the source host to the destination host solely based on their addresses. For this purpose the Internet Protocol defines addressing methods and structures for datagram encapsulation.

netbios

NetBIOS (pronounced / ˈnɛtbaɪ.ɒs/) is an acronym for Network Basic Input/Output System. It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol.

cpu


A central processing unit (CPU) or processor is an electronic circuit that can execute computer programs. This topic has been in use in the computer industry at least since the early 1960s (Weik 1961). The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation has remained much the same.

coxial cable


Coaxial cable, or coax, is an electrical cable with an inner conductor surrounded by a tubular insulating layer typically of a flexible material with a high dielectric constant, all of which are surrounded by a conductive layer (typically of fine woven wire for flexibility, or of a thin metallic foil), and finally covered with a thin insulating layer on the outside.

network switch


A network switch is a computer networking device that connects network segments.
The term commonly refers to a Network bridge that processes and routes data at the Data link layer (layer 2) of the OSI model. Switches that additionally process data at the Network layer(layer 3 and above) are often referred to as Layer 3 switches or Multilayer switches.

network card


A network card, network adapter, network interface controller (NIC), network interface card, or LAN adapter is a computer hardware component designed to allow computers to communicate over a computer network. It is both an OSI layer 1 (physical layer) and layer 2 (data link layer) device, as it provides physical access to a networking medium and provides a low-level addressing system through the use of MAC addresses. It allows users to connect to each other either by using cables or wirelessly.

modem


Modem (from modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used over any means of transmitting analog signals, from driven diodes to radio.

analogue signals


An analog or analogue signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e analogous to another time varying signal. It differs from a digital signal in that small fluctuations in the signal are meaningful. Analog is usually thought of in an electrical context; however, mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.

wifi






Wi-Fi (pronounced is a trademark of the Wi-Fi Alliance for certified products based on the standards. This certification warrants interoperability between different wireless devices.

Internet


The Internet is a global system of interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP). It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies.

lan


A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN).
Most LANs connect workstations and personal computers.

diego armando maradona


Diego Armando Maradona (born 30 October 1960 in Lanús, Buenos Aires) is a former Argentine football player, and current coach of the Argentine national side. He finished first in an internet vote for the FIFA Player of the Century award, and shared the award with Pelé.
Over the course of his professional club career Maradona played for Argentinos Juniors, Boca Juniors, Barcelona, and, most distinguishedly, Napoli. In his international career, playing for Argentina, he earned 91 caps and scored 34 goals. He played in four FIFA World Cup tournaments, including the 1986 World Cup where he captained Argentina and led them to their victory over West Germany in the final, winning the Golden Ball award as the tournament's best player. In that same tournament's quarter-final round he scored two remarkable goals in a 2-1 victory over England which instantly cemented his fame. The first goal was an unpenalized handball known as the "Hand of God", while the second goal was a spectacular 60-metre weave through six England players, commonly referred to as "The Goal of the Century".
