This change to lazy evaluation saves execution time for large ranges which may never be fully referenced and memory usage for large ranges where only one or a few elements are needed at any time. In Python 2.x is possible to use a function called xrange() which returns an object that generates the numbers in the range on demand.
Delta time or delta timing is a concept used amongst programmers in relation to hardware and network responsiveness. [1] In graphics programming, the term is usually used for variably updating scenery based on the elapsed time since the game last updated, [2] (i.e. the previous "frame") which will vary depending on the speed of the computer, and how much work needs to be done in the program at ...
The scheduler is given the information needed to implement priority inheritance or other mechanisms to avoid starvation. Busy-waiting itself can be made much less wasteful by using a delay function (e.g., sleep()) found in most operating systems. This puts a thread to sleep for a specified time, during which the thread will waste no CPU time.
The time delay is usually measured in slots, which are fixed-length periods (or slices) of time on the network. In a binary exponential backoff algorithm (i.e. one where b = 2), after c collisions, each retransmission is delayed by a random number of slot times between 0 and 2 c − 1. After the first collision, each sender will wait 0 or 1 ...
JIT causes a slight to noticeable delay in the initial execution of an application, due to the time taken to load and compile the input code. Sometimes this delay is called "startup time delay" or "warm-up time". In general, the more optimization JIT performs, the better the code it will generate, but the initial delay will also increase.
The round-trip time or ping time is the time from the start of the transmission from the sending node until a response (for example an ACK packet or ping ICMP response) is received at the same node. It is affected by packet delivery time as well as the data processing delay, which depends on the load on the responding node. If the sent data ...
At the same time, Carol's application layer will not send a response until it gets all of the data. If Carol is using delayed ACKs, her socket layer will not send an ACK until the timeout is reached. If the application is transmitting data in smaller chunks and expecting periodic acknowledgment replies, this negative interaction can occur.
Time to live (TTL) or hop limit is a mechanism which limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded or revalidated.
