The electricity that people use is generally produced and supplied by companies. Load shedding
results when people are demanding more electricity than a company has to give. To resolve the situation, that company may have to deny certain users electricity at certain times. Load shedding
is sometimes referred to as rolling blackouts. This can be a bit deceiving since blackouts are generally unplanned.
Many people take electricity for granted. This is often because people think electricity is unlimited. In many parts of the world, especially in developing countries, this is not true.
Providing electricity involves converting some type of resource into energy that can be used to produce the needed electricity. For example, coal or hydropower
may be used. Companies involved in this process usually have a limited capacity, meaning they can only produce so much. There are also instances when the resources used to produce the electrical power are limited or unavailable.
Load shedding
occurs when consumers demand levels of supply that exceed their providers' capacities. When these types of threats are looming, people are often warned to conserve electricity and limit their consumption. This strategy often proves ineffective, so the providers must resort to more drastic measures.
A blackout is usually an uncontrolled power outage. If excessive demands are left unresolved, this will be the result. Blackouts, however, can be problematic. Since consumers have no indication of when a blackout will occur, they can be unduly inconvenienced. For providers, blackouts can result in damaged networks.
Load shedding
is a controlled alternative response to excessive demand. To ease the burden on themselves and their consumers, providers may begin to ration electricity. Instead of allowing a blackout to occur, which could cause many people to be without power for an unknown amount of time, providers may shut down the flow themselves.
This is usually part of a plan. The providers decide how to best distribute the electricity so the burden of the shortage can be spread across their networks. Load shedding
often involves schedules that determine which areas will be denied power and at what times it will happen.
Load shedding
is referred to as rolling blackouts for this reason. First, the flow of electricity is cut in one area for a predetermined amount of time. Then, supplies are reconnected in that area and disconnected elsewhere. In many cases people in the affected areas, especially the businesses such as supermarkets that are dependent on power, are notified in advance.

How do you configure the gateway of those in the network lan?
When configuring a gateway within a network, usually one will want to enable DHCP to allow the gateway to give out automatic IP information which includes, IP (Internet Protocol Address), Subnet Mask,Default Gateway and DNS address's. When talking on a home user level, a gateway is a router and vice versa, they are one and the same. If talking about a business environment then the router can be configured to route computers to the gateway in stead of having the router do DHCP it will just route all it's traffic to the gateway by using a static IP that would be the address of the gateway. In this configuration you would need to configure all the computers to each use a unique IP address usually in the form of 192.168.x.x (were x is a number)
