One reason for the deadlock was that the technical development of weapons gave a massive advantage to defenders. The development of bolt action, breach loading rifles greatly increased the fire power of infantry; a regular British soldier in 1914 was trained to fire 15 rounds per minute.
Why did using trench warfare cause a stalemate?
The war had reached a stalemate, a state where both sides are so evenly balanced that neither can breakthrough against the enemy. The advances in Technology played a big role in creating the stalemate through strong defensive weaponry such as Machine Guns and Artillery, this caused ‘trench warfare’ (BOOK 48).
What broke the deadlock of trench warfare?
In their search for a weapon that could break the stalemate on the western front, generals turned to a frightening new weapon – poisonous gas. On 22 April 1915 near Ypres, the Germans released chlorine gas from cylinders and allowed the wind to blow the thick, green vapour across to the Allied trenches.
Why did the soldiers put down wooden boards in the bottom of the trenches?
In the trench itself, the bottom was covered with wooden boards called duckboards. These were meant to protect the soldiers’ feet from the water in the trenches to try and prevent Trench Foot.
How were dead bodies used in the trenches?
How did soldiers use dead bodies in the trenches? Many men killed in the trenches were buried almost where they fell. If a trench subsided, or new trenches or dugouts were needed, large numbers of decomposing bodies would be found just below the surface. …
Which technology helped bring trench warfare to a stalemate?
The difficulties of successfully taking an enemy’s trenches defended with machine guns and lined with barbed wire meant that the war on the western front lapsed into stalemate.
What key invention finally helped end the stalemate in the trenches?
French Materiel captured by the Germans in 1915 on the Argonne front. Gas attacks were increasingly common as the war drug on. Soldiers were not the only ones who needed protection! Near the end of the war, the first effective tanks helped to break the stalemate.
How was the deadlock broken in ww1?
The nature of warfare on the western front meant that trenches were dug. this meant that a stalemate situation led to no movement in that area, it was a deadlock. Both Britain and Germany were keen to develop weapons to break the deadlock. These machine gun, artillery,tanks and gas were used to break the deadlock.
Did tanks end stalemate?
The tank was invented to break the stalemate of trench warfare on World War I’s European battlefields. Artillery and machine guns, plentiful on both sides, were particularly effective against the main form of offense—the infantryman.
How was trench warfare broken?
The combination of wire and firepower was the cause of most failed attacks in trench warfare and their very high casualties. Liddell Hart identified barbed wire and the machine gun as the elements that had to be broken to regain a mobile battlefield.
What factors contributed to the stalemate?
This stage further develops students’ understanding of the causes of stalemate during the First World War by exploring four causes of stalemate: The Trench system, the effective use of a machine gun as a defensive weapon, the difficulty crossing No-man’s land and the use of railways to mobilise/transfer troops.
Why was it difficult to gain an advantage over the enemy in trench warfare?
Why was it difficult to gain an advantage over the enemy in trench warfare? Too many soldiers died of disease in the trenches. The machine gun made it nearly impossible for troops to advance. No weapons were used.
What is a deadlock in war?
Definition of deadlock
1 : a state of inaction or neutralization resulting from the opposition of equally powerful uncompromising persons or factions : standstill the deadlock was broken with a key compromise. 2 : a tie score.
What is deadlock explain?
A deadlock is a situation in which two computer programs sharing the same resource are effectively preventing each other from accessing the resource, resulting in both programs ceasing to function. The earliest computer operating systems ran only one program at a time.
Why does deadlock occur?
Deadlock occurs when a set of processes are in a wait state, because each process is waiting for a resource that is held by some other waiting process. Therefore, all deadlocks involve conflicting resource needs by two or more processes.
What is deadlock how do you prevent it?
Deadlock can be prevented by eliminating any of the four necessary conditions, which are mutual exclusion, hold and wait, no preemption, and circular wait. Mutual exclusion, hold and wait and no preemption cannot be violated practically. Circular wait can be feasibly eliminated by assigning a priority to each resource.
What are the 4 conditions of deadlock?
The four necessary conditions for a deadlock situation are mutual exclusion, no preemption, hold and wait and circular set.
Why is deadlock state more critical than starvation?
deadlock state is more critical than starvation because-
deadlock is said to happen when the there is a limited resource but there are multiple processes in the CPU who are competing against each other to get that limited resource.
What is starvation OS?
Starvation is the problem that occurs when high priority processes keep executing and low priority processes get blocked for indefinite time. In heavily loaded computer system, a steady stream of higher-priority processes can prevent a low-priority process from ever getting the CPU.
What is deadlock in Java?
Deadlock in Java is a condition where two or more threads are blocked forever, waiting for each other. This usually happens when multiple threads need the same locks but obtain them in different orders. Multithreaded Programming in Java suffers from the deadlock situation because of the synchronized keyword.
What happens if we start a thread twice?
After starting a thread, it can never be started again. If you does so, an IllegalThreadStateException is thrown. In such case, thread will run once but for second time, it will throw exception.
How do you create a thread pool in Java?
To use thread pools, we first create a object of ExecutorService and pass a set of tasks to it. ThreadPoolExecutor class allows to set the core and maximum pool size. The runnables that are run by a particular thread are executed sequentially. Method Description newFixedThreadPool(int) Creates a fixed size thread pool.
What code can create deadlock?
Deadlock occurs when multiple threads need the same locks but obtain them in different order. A Java multithreaded program may suffer from the deadlock condition because the synchronized keyword causes the executing thread to block while waiting for the lock, or monitor, associated with the specified object.
What is starvation in Java?
Starvation describes a situation where a thread is unable to gain regular access to shared resources and is unable to make progress. This happens when shared resources are made unavailable for long periods by “greedy” threads.
What is a thread in Java?
A thread is a thread of execution in a program. The Java Virtual Machine allows an application to have multiple threads of execution running concurrently. Every thread has a priority. Threads with higher priority are executed in preference to threads with lower priority.
What is volatile keyword in Java?
The volatile modifier is used to let the JVM know that a thread accessing the variable must always merge its own private copy of the variable with the master copy in the memory. Accessing a volatile variable synchronizes all the cached copied of the variables in the main memory.
What does volatile do in C++?
The volatile qualifier is applied to a variable when we declare it. It is used to tell the compiler, that the value may change at any time.
What is multithreading How does Java support multithreading?
Multithreading is a Java feature that allows concurrent execution of two or more parts of a program for maximum utilization of CPU. Each part of such program is called a thread. So, threads are light-weight processes within a process.
How do you use yield in Java?
A yield() method is a static method of Thread class and it can stop the currently executing thread and will give a chance to other waiting threads of the same priority. If in case there are no waiting threads or if all the waiting threads have low priority then the same thread will continue its execution.
How do you yield in Python?
yield in Python can be used like the return statement in a function. When done so, the function instead of returning the output, it returns a generator that can be iterated upon. You can then iterate through the generator to extract items. Iterating is done using a for loop or simply using the next() function.
What is thread yield C#?
Causes the calling thread to yield execution to another thread that is ready to run on the current processor. The operating system selects the thread to yield to. public: static bool Yield(); C# Copy.
