"Disk Defragmentation" overview
Disk Defragmentation Programs Determine the location of fragmented files and folders locally.
When a volume contains a lot of fragment files and folders, Windows accesses their time to grow because it needs some additional disk drive readings to collect different parts of the file and folders. Because the available space on the volume is zero, it is slow to create a new file and folder. Then Windows must save the new files and folders to different locations on the volume.
Disk Defragmentation Moves the fragmentation of each file or folder to a location on the volume so that each file or folder occupies separate, continuous spaces on the disk drive. This allows your system to access your files and folders more effectively and save new files and folders. By merging files and folders, the disk fragmentation process also combines the available space, reduces the possibility of new files into fragments.
Finding, the process of merged files and folder fragments is called fragmentation. The time spent by fragmentation depends on multiple factors, including the size of the volume, the number of files, the number of pieces, and the available local system resources. Analyze the volume before fragmentation of files and folders, you can find all debris files and folders. Then, you can see how much the shard files and folders saved on the volume and decide whether to sharpen the volume.
The disk defragmentation program can defragment file system formatted using the file allocation table (FAT32, and NTFS file system.
Why is a fragmentation in a volume
Fragments are started when the user creates and deletes files and folders, install new software or download files from the Internet. Computers do not have to save the entire file or folder in a space, but save these files and folders in the first available space of the volume. Most new files are stored in the shards in the volume when most of the space in the volume is used as a store and folder. When the file or folder is deleted, the remaining space will be randomly populated when the new file is stored.
The more fragments in the volume, the lower the computer's file input / output system performance.
Message queue overview
Message queues are the foundation of the message application in the Windows 2000 operating system and a development tool for creating a distributed, loosening message communication application. Applications developed for message queues can send messages to queues, which are used to ensure that messages can reach the temporary storage location of the target. These applications can communicate through different kinds of networks, or with offline computer. Message queues provide guaranteed messaging, valid route, security, transaction support, and priority-based messaging. Software products with these functions typically call messages in the industry, store forwarding software or intermediates for messages.
With message queues, end users can communicate between disconnected networks and computers regardless of the current state of the network and computers. System administrators can efficiently manage large complex computers and message queue networks with message queues. Through the message queue, MIS decision makers can get a more reliable communication and use network resources more effectively. Developers can only focus on business rules without having to care about network issues because the message queue can effectively provide reliable network communication.
System administrators responsible for installing and managing infrastructure and creating software developers who create message applications should be particularly interested in messages. This document is written for system administrators, so only the infrastructure and functional problems provided by message queues are discussed without discussing how to develop applications.
