Multiprogrammingrefers to the concurrent execution of multiple programs on a single CPU. The CPU switches rapidly between programs, providing the illusion that they're all running simultaneously. The main benefi
Essentially, liveness is the ability of concurrent applications to execute threads on time – without delays and locks. However, it is not possible all the time in Java Concurrency. When two or more threads try to access the same resource, it creates thread contention. As a result, the Java...
Lock manager.This crucial component of the DBMS manages concurrent access to the same data. Locks are required to ensure multiple users aren't trying to modify the same data simultaneously. Log manager.The DBMS records all changes made to data managed by the DBMS. The record of changes is kn...
Concurrent monitoring is now supported in the Serial Monitor. Concurrent monitoring allows you to monitor multiple ports at the same time side by side. Press the plus button to open another Serial Monitor and get started. You can now view properties from base classes modified in an Unreal Blue...
Concurrent programming is not equivalent to parallel execution, despite the fact that these two terms are often being used interchangeably. Illustration of concurrency without parallelism Concurrency is a property which more than one operation can be run simultaneously but it doesn’t mean it will be...
Like many Java developers, the first time I heard about lambda expressions it piqued my interest. Also like many others, I was disappointed when it was set back. However, it is better late than never. Java 8 is a giant step forward for the Java language. Writing this book has forced me...
and watchOS 11. Widgets on Apple Watch now support interactivity and animations, and widgets on iPhone and iPad allow for accenting specific parts of a widget to make them stand out when the Home Screen is tinted. The Smart Stack in watchOS 11 is even smarter with the ability to add relev...
Root causes for failures are found by carefully tracing execution that leads to failureRoot causes are found by postulating a race that fits the behavior and methodically reviewing the code for possible causes Once identified, finding a fix for a bug is generally assuredThe root cause for a rac...
Replication delays, network issues or conflicts in concurrent updates can cause data schema and data profiling anomalies, such as null counts, type changes and skew. Data loss While data replication is often used for data backup and disaster recovery, not all replication strategies provide real-...
