Online scheduling is the useage of competitive analysis (or online algorithms) on scheduling problems. Online algorithms is characterized by making decision "online", which means a point in the time axe. In this point of time, we can not see the future jobs or tasks, whereas we only know the jobs or tasks before or at this point of time. In contrast, in offline scheduling problems, there is no the conception of "point of time". We are lords of the world. We stay outside the real world and can see the past and future (jobs or tasks). TThis aspect is called "offline". Since we can see the past and the future, we know the total knowledge of the problem before we make decision (not depending the time). Even use the simpliest method, such as enumeration, then we can obtain the optimal solution. Nontheless, by not knowing the future knowledge of problem, we must make decision. Then we use a critierion to meaure the performance of online algorithm, called competitive ratio. This is a conception like approximation ratio, compering the objective value obtained by online algorithm and that of offline (optimal) algorithm. Offline scheduling is concerned of the classical scheduling problems. Not introducing the conception of "online". Offline scheduling problem is scheduling problem.
what are the different between online and offline Data Processing
Online means you are on the site. Offline means you aren't. Online= Logged on-Offline=Logged off
online is were you are conected to a server and offline is were you are not
researh about accessing help online/offline
Online.
You need to right click where it says you are offline it will give you a list of options. Such as appear offline and appear online.
it is online and offline
well offline that you cant do unless you cant connect to a wifi. online you can do but you have to select it
At specific times you define
no if online yes if offline
you need to be connected to be in offline mode. obviously.
Because your offline and you haven't logged in.
