Module 02: Networking Fundamentals Exam ECSS

Network Networking( Network, Networking ) is a cluster of computer hardware connected together physically or logica

Network Networking( Network, Networking ) describes the processes involve—gn designing, implementing, upgradirw
managing of networks

networks may differ in many ways. For example: by size, by functions, by the
geographical distance.

LOCAL (LAN) < >( <, > ) WIDE AREA NETWORK (WAN)< >( <, > )METROPOLITAN AREA NETWORK (MAN)

LAN WAN MAN( LAN, WAN, MAN ) - home, office building, school, normalmente privada o de una organización
LAN WAN MAN( LAN, WAN, MAN ) - conects 2 or more LAN over a public network .
LAN WAN MAN( LAN, WAN, MAN ) - LAN are connected using fiber optical

PERSONAL AREA NETWORK (PAN CAN( PAN, CAN )) Room-Size: Bluethooth, RF, NGC, etc

CAMPUS AREA NETWORK (PAN CAN( PAN, CAN )) University

GLOBAL AREA NETWORK (PAN GAN( PAN, GAN )) Combination different computer networks; Unlimited geographical area

Las capas que ENVIAN cosas son:

en TCP/IP - transporte transport( transporte, transport )

en OSI hay dos:

Data Link data link( Data Link, data link ) para LAN,
NETWORK(red) network(red)( NETWORK(red), network(red) )(Red en español) para routear a otras redes
