تعريف
network management
<networking> The process of controlling a network so as to
maximise its efficiency and productivity. ISO's model
divides network management into five categories: {fault
management}, accounting management, {configuration
management}, security management and {performance
management}.
Fault management is the process of identifying and locating
faults in the network. This could include discovering the
existence of the problem, identifying the source, and possibly
repairing (or at least isolating the rest of the network from)
the problem.
Configuration management is the process of identifying,
tracking and modifying the setup of devices on the network.
This category is extremely important for devices that come
with numerous custom settings (e.g. routers and {file
servers}).
Security management is the process of controlling (granting,
limiting, restricting or denying) access to the network and
resources thereon. This could include setting up and managing
access lists in routers (creating "firewalls" to keep
intruders out), creating and maintaining password access to
critical network resources, identifying the points of entry
used by intruders and closing them.
Performance Management is the process of measuring the
performance of various network components. This also includes
taking measures to optimise the network for maximum system
performance (periodically measuring of the use of network
resources).

ويكيبيديا
1G
1G refers to the first generation of cellular network (wireless) technology. These are mobile telecommunications standards that were introduced in the 1980s and were superseded by 2G. The main difference between these two mobile cellular generations is that the audio transmissions of 1G networks were analog, while 2G networks were entirely digital.
There were many different 1G cellular standards developed and used in different countries, but the most widely adopted globally were the Nordic Mobile Telephone (NMT) and Advanced Mobile Phone System (AMPS) systems. The inherent advantages of digital technology over that of analog meant that 2G networks went on to eventually completely replace them. Many 1G networks were switched off in developed economies by 2000, but in some places networks continued to operate into the 2010s.
