What does Synchronise mean?
verb (used with object), syn·chro·nized, syn·chro·niz·ing. to cause to indicate the same time, as one timepiece with another: Synchronize your watches. to cause to go on, move, operate, work, etc., at the same rate and exactly together: They synchronized their steps and walked on together.

Why is synchronization needed?
Synchronization control the access the multiple threads to a shared resources. Without synchronization of threads, one thread can modify a shared variable while another thread can update the same shared variable, which leads to significant errors.
Why is synchronization important in communication?
Timing and carrier synchronization is a fundamental requirement for any wireless communication system to work properly. Timing synchronization is the process by which a receiver node determines the correct instants of time at which to sample the incoming signal.
What is the use of synchronization?
To avoid such issues, Java provides us with the synchronized keyword, which acts like a lock to a particular resource. This helps achieve communication between threads such that only one thread accesses the synchronized resource and other threads wait for the resource to become free.
What is race condition in operating systems?
A race condition occurs when a software program depends on the timing of one or more processes to function correctly. If a program relies on threads that run in an unpredictable sequence, a race condition may occur. A simple example is a logic gate that handles boolean values.
What is race condition give an example?
□ A “race condition” arises if two or more threads. access the same variables or objects concurrently. and at least one does updates. □ Example: Suppose t1 and t2 simulatenously execute. the statement x = x + 1; for some static global x.
What is race around condition and how it can be avoided?
When the S and R inputs of an SR flip flop is at logical 1 and then the input is changed to any other condition, then the output becomes unpredictable and this is called the race around condition. If the clock on or high time is less than the propagation delay of the flip flop then racing can be avoided.
What causes race condition?
A race condition occurs when two threads access a shared variable at the same time. The first thread reads the variable, and the second thread reads the same value from the variable.
What is race condition in multithreading and how can we solve it?
an easy way to fix “check and act” race conditions is to synchronized keyword and enforce locking which will make this operation atomic and guarantees that block or method will only be executed by one thread and result of the operation will be visible to all threads once synchronized blocks completed or thread exited …
How do you fix race conditions?
Race conditions can be avoided by proper thread synchronization in critical sections. Thread synchronization can be achieved using a synchronized block of Java code. Thread synchronization can also be achieved using other synchronization constructs like locks or atomic variables like java.
How can I check my race condition?
Using RapiTest to test potential race conditions
- Design and run a multi-threaded test.
- Identify potential race conditions.
- Visualize the interactions between threads.
What is toggle condition?
[′täg·əl kən‚dish·ən] (electronics) Condition of a flip-flop circuit in which the internal state of the flip-flop changes from 0 to 1 or from 1 to 0.
What is AJK flip flop?
The flip flop is a basic building block of sequential logic circuits. It is a circuit that has two stable states and can store one bit of state information. The basic JK Flip Flop has J,K inputs and a clock input and outputs Q and Q (the inverse of Q). …
What is toggling in flip flop?
The T or “toggle” flip-flop changes its output on each clock edge, giving an output which is half the frequency of the signal to the T input. It is useful for constructing binary counters, frequency dividers, and general binary addition devices. It can be made from a J-K flip-flop by tying both of its inputs high.
What does toggling mean?
transitive verb. 1 : to fasten with or as if with a toggle. 2 : to furnish with a toggle. 3 : to switch between two different options for (something, such as a computer setting) usually by pressing a single button or a simple key combination toggle the sound on a computer off and on.
Where are latches used?
Latches are single bit storage elements which are widely used in computing as well as data storage. Latches are used in the circuits like power gating & clock as a storage device. D latches are applicable for asynchronous systems like input or output ports.
What is difference between latches and flip flop?
The difference between a latch and a flip-flop is that a latch is level-triggered (outputs can change as soon as the inputs changes) and Flip-Flop is edge-triggered (only changes state when a control signal goes from high to low or low to high).
What are the different types of latches?
There are basically four main types of latches and flip-flops: SR, D, JK, and T. The major differences in these flip-flop types are the number of inputs they have and how they change state.
