connection oriented

connection-oriented:-

connection-oriented describes a means of transmitting data in which the devices at the end points use a preliminary protocol to establish an end-to-end connection before any data is sent. Connection-oriented protocol service is sometimes called a "reliable" network service, because it guarantees that data will arrive in the proper sequence. Transmission Control Protocol (TCP) is a connection-oriented protocol.

For connection-oriented communications, each end point must be able to transmit so that it can communicate. The alternative to connection-oriented transmission is the connection-less approach, in which data is sent from one end point to another without prior arrangement. Connection-less protocols are usually described as stateless because the end points have no protocol-defined way to remember where they are in a "conversation" of message exchanges. Because they can keep track of a conversation, connection-oriented protocols are sometimes described as statefulI.

The Seven-Step Model of Migration

Irrespective of the migration approach adopted, the Seven-step Model of Cloud Migration creates a more rational point of view towards the migration process and offers the ability to imbibe several best practices throughout the journey Step 1: Assess Cloud migration assessments are conducted to understand the complexities in the migration process at the code, design and architectural levels. The investment and the recurring costs are also evaluated along with gauging the tools, test cases, functionalities and other features related to the configuration. Step 2: Isolate The applications to be migrated to the cloud from the internal data center are freed of dependencies pertaining to the environment and the existing system. This step cuts a clearer picture about the complexity of the migration process. Step 3: Map Most organisations hold a detailed mapping of their environment with all the systems and applications. This information can be used to distinguish between the ...

Special Permissions in linux

The setuid permission on an executable file means that the command will run as the user owning the file, not as the user that ran the command. One example is the passwd command: [student@desktopX ~]$ ls -l /usr/bin/passwd -rw s r-xr-x. 1 root root 35504 Jul 16 2010 /usr/bin/passwd In a long listing, you can spot the setuid permissions by a lowercase s where you would normally expect the x (owner execute permissions) to be. If the owner does not have execute permissions, this will be replaced by an uppercase S . The special permission setgid on a directory means that files created in the directory will inherit their group ownership from the directory, rather than inheriting it from the creating user. This is commonly used on group collaborative directories to automatically change a file from the default private group to the shared group, or if files in a directory should be...
