Extract of sample "Operating Systems"

Operating Systems The two sections that important for this discussion are the Linux I/O and Windows I/O. The Linux I/O service mainly offers the tools used for program profiling and monitoring the performance of the computer CPU. Disk scheduling in Linux allows the execution of many program processes at the same time. The Linux Page Cache aids in fast data access and transmission. This is because during an I/O operation, such as disk read information, the operating system kernel checks for data in the page cache to facilitate fast reading of the data.
The advancements in the Linux I/O services is the optimization of disk scheduling through the use of multilevel queues and priority scheduling to enable the execution of many program processes. Setting these commands provides an end user with the robust set of tools to manage file operation and process execution within an operating system. The Linux I/O services will change society a great deal since the optimization of disk scheduling and page cache services are essential for quick program execution, therefore saving time. It is also important for performing read/write services on a computer hard disk (memory) through satisfying fast mapping of data (Bovet, Daniel & Marco 599).
The Windows I/O concept offers subjects that describe the applications that control the input and output services that assist in data access from and data writing to the computer hard disk (memory). One basic I/O facility utilized by window operating system is the Asynchronous and Synchronous I/O, which both offer necessary operations for facilitating communication and fast processing of information within a system. In a synchronous I/O operation, programs are placed on a wait state while in an asynchronous I/O operation; program or process execution request can be interrupted to enable the execution of another program (Russinovich, Mark, David & Alex Ch. 7).
The advancements made in the basic windows I/O operations include the optimization of processing efficiency. This mechanism majorly entails the processing of large data or information within the shortest time possible without having to interrupt other prior made I/O requests made by a system user. Uninterrupted program execution ensures there is no loss of data or delay of displaying outputs during the I/O operations.

...? Operating Systems Design of a backup program in batch file running on MS DOS This project involves the development of an automatic back up program in batch file for MS DOS operating system and for Bash Shell. The program will interact with the user in a dialogue and request for the directory name as an option for back up location. It is a fully documented program with a bat extension. In the user interaction, it checks if the user back up directory is available, then proceeds with the backup process (Cavanagh, 2002). In the absence of the backup directory, it asks the user for an alternative directory. This program is in the complicity level three since it is able to create a batch file to run the automatic back up process... . The...

...Investigation of How Memory Is Implemented In a Modern Operating System Such As WindowsXP Microsoft Corporation recommends that computers running Windows XP have at least 128 megabytes (MB) of Random Access Memory (RAM) installed. For this memory size, Windows XP has shown itself to be consistently superior to previous versions of Windows. Performance only gets better with additional resources, particularly when you run memory-intensive multimedia applications. Many users will want to expand their computer's memory to take advantage of multimedia applications and to achieve even better performance. In general, adding memory is the easiest and most effective way to improve a computer's performance....
