Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun.

• Kepler’s three laws of planetary motion can be stated as follows:

(1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci.

(2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.

(3) The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun.

Word and WordPad can save documents as ASCII text and HTML, but this approach can lead to problems. NotePad should launch with a new document open.

From the File pull-down menu, Select "Save As," save the file to the Desktop, and name the file using the ".html" extension (e.g., "home.html").

RAM stands for Random Access Memory.

AutoSys is an automated job control system for scheduling, monitoring, and reporting. These jobs can reside on any AutoSys-configured machine that is attached to a network.

However, in real business, you need to fire jobs not just based on scheduled time, but also based on events (like an arrival of a file), and, based on the success or failure of other jobs. Autosys is a total job scheduling solution that allows you to define these events, dependencies, time schedules, alerts, etc, making it a complete data center automation tool.

One of two sublayers of the data link layer of OSI reference model, as defined by the IEEE 802 standard. This sublayer is responsible for maintaining the link between computers when they are sending data across the physical network connection

• An Interpreter is a program that reads in as input a source program, along with data for the program, and translates the source program step by step.

The Java interpreter decodes each lines bytecode and runs a series of machine instructions for that bytecode. The JVM takes the byte code and generates machine code. The byte code is compiled to machine code, and the machine code is executed.

A data structure is a specialized format for organizing and storing data. General data structure types include the array, the file, the record, the table, the tree, and so on. Any data structure is designed to organize data to suit a specific purpose so that it can be accessed and worked with in appropriate ways.

Linear data structure: A linear data structure traverses the data elements sequentially, in which only one data element can directly be reached.

Ex: Arrays, Linked Lists, Stack, Queue, Any type of List all are linear.

Trees like Binary Tree, B Tree or B+ Tree are examples of non linear data structure.

It is the protocol the routers in neighboring autonomous systems use to identify the set of networks that can be reached within or via each autonomous system.
