Mouse without Borders - This is a Garage product from Microsoft that allows a single keyboard and mouse to operate up to four different computers. Barrier – A Creative Commons fork of Synergy's 1.9 branch.
In computing, a memory barrier, also known as a membar, memory fence or fence instruction, is a type of barrier instruction that causes a central processing unit (CPU) or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction. This typically means that operations issued prior to the ...
The cursor for the Windows Command Prompt (appearing as an underscore at the end of the line). In most command-line interfaces or text editors, the text cursor, also known as a caret, [4] is an underscore, a solid rectangle, or a vertical line, which may be flashing or steady, indicating where text will be placed when entered (the insertion point).
In operating systems, write barrier is a mechanism for enforcing a particular ordering in a sequence of writes to a storage system in a computer system. For example, a write barrier in a file system is a mechanism (program logic) that ensures that in-memory file system state is written out to persistent storage in the correct order. [1] [2] [3]
Snap!'s blocks are divided into eight groups: Motion, Looks, Sound, Pen, Control, Sensing, Operators, and Variables. The layout of these groups in the block group selector is shown in the table below. The central area can show scripts, costumes/backdrops, or sounds associated with the selected sprite. What that area shows depends on the ...
Most locking designs block the execution of the thread requesting the lock until it is allowed to access the locked resource. With a spinlock, the thread simply waits ("spins") until the lock becomes available. This is efficient if threads are blocked for a short time, because it avoids the overhead of operating system process re-scheduling.
Wait-freedom is the strongest non-blocking guarantee of progress, combining guaranteed system-wide throughput with starvation-freedom.An algorithm is wait-free if every operation has a bound on the number of steps the algorithm will take before the operation completes. [15]
An obstacle (also called a barrier, impediment, or stumbling block) is an object, thing, action or situation that causes an obstruction. [1] A obstacle blocks or hinders our way forward. Different types of obstacles include physical, economic , biopsychosocial , cultural, political, technological and military.
