The Intel 8086 and subsequent processors in the x86 series have an HLT (halt) instruction, opcode F4, which stops instruction execution and places the processor in a HALT state. An enabled interrupt, a debug exception, the BINIT signal, the INIT signal, or the RESET signal resumes execution, which means the processor can always be restarted. [15]
For example, in FreeBSD the ATA/CAM stack controls the timeouts, and is set to progressively increase the timeouts as they occur. Thus, if a desktop disk without TLER starts delaying a response to a sector read, FreeBSD will retry the read with successively longer timeouts to prevent prematurely dropping the disk out of the array.
For example, Windows NT/XP/Vista uses a multilevel feedback queue, a combination of fixed-priority preemptive scheduling, round-robin, and first in, first out algorithms. In this system, threads can dynamically increase or decrease in priority depending on if it has been serviced already, or if it has been waiting extensively.
Code cleanup can also refer to the removal of all computer programming from source code, or the act of removing temporary files after a program has finished executing. For instance, in a web browser such as Chrome browser or Maxthon , code must be written in order to clean up files such as cookies and storage. [ 6 ]
In computing, a process that is blocked is waiting for some event, such as a resource becoming available or the completion of an I/O operation. [1] Once the event occurs for which the process is waiting ("is blocked on"), the process is advanced from blocked state to an imminent one, such as runnable.
The taskkill command on Microsoft Windows. In Microsoft's command-line interpreter Windows PowerShell, kill is a predefined command alias for the Stop-Process cmdlet. Microsoft Windows XP, Vista and 7 include the command taskkill [5] to terminate processes. The usual syntax for this command is taskkill /im "IMAGENAME".
The installed disks and their associated volumes and/or partitions can be viewed using these commands: list disk list volume list partition The sel command will select them. The command clean will perform a "quick" disk wipe, and clean all zeroes out the entire partition/disk.
A more common use case is the invocation of badblocks as part of e2fsck when passing the option "-c" to scan for bad blocks and prevent data from being stored on these blocks. This is done by adding the list of found bad blocks to the bad block inode to prevent the affected sectors from being allocated to a file or directory.
