CS and IP. Here, a brief introduction and how to start working is given..

What is Python? Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together.

Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Networking and Open Standards Computer Networking: Hub, Switch, Repeater, Gateway — and their functions Types of network: Star, Bus, Tree Network Protocols: Unit 2: String class and methods: Web application development: Grouping Records: Displaying Data From Multiple Tables: IT Applications Front-end Interface: Back-end Database: Introduction and its purpose, exploring the requirement of tables and its essential attributes.

Front-End and Database Connectivity: Introduction, requirement and benefits Demonstration and development of appropriate Front-end interface and Back-end Database for e-Governance, e-Business and e-Learning applications Impact of ICT on society: Social, environmental and Economic benefits.

Evaluation of Practical Examination 1. Problem Solving using Java Student is required to solve programming problems based on all concepts covered in theory throughout the year and maintain a record of these in the practical file.

Student will be asked to write four queries based on one or two tables during final practical examination to be conducted at the end of the academic session 3. Practical Record File A practical record file is required to be created during the entire academic session.

Recall when you throw a stone in a pond, circular waves are generated and spread outwards.

Similarly, radio waves are generated by the transmitter and spread in all the directions. Relatively inexpensive than wired media. It offers ease of communication over difficult terrain The transmission can be interfered by motors or other electrical equipment Permission from concerned authorities is required for use of radio wave transmission Less secure mode of transmission Micro waves have a frequency range of MHz 0.

This range has some overlapping portion 0. Microwaves travel in straight lines and cannot penetrate any solid object.

Therefore for long distance microwave communication, high towers are built and microwave antennas are put on their tops.As the data goes from one point to another point on the Internet, for example, it may pass through several points along the way, giving other users the opportunity to access, and even alter it. A strong password is the one which is easy to.

An RJ connecter is used to connect this cable to a computer. Operators are symbols that manipulate, combine or compare variables. LANs c. Since there is no compilation step, the edit-test-debug cycle is incredibly fast.

The main characteristic of the while loop is that it can be used in both cases i. These waves are easy to build but have a major drawback- they do not pass through solid objects try standing between your remote control and your television and see if it still works.
