Dynamic Programming
Dynamic Programming is mainly an optimization over plain recursion. Wherever we see a recursive solution that has repeated calls for same inputs, we can optimize it using Dynamic Programming. The idea is to simply store the results of subproblems, so that we do not have to re-compute them when needed later.

ISO-OSI 7-Layer Network Architecture
The International Standards Organization (ISO) developed the Open Systems Interconnection (OSI) model. It divides network communication into seven layers. ... Layers 5-7, called the the upper layers, contain application-level data. Networks operate on one basic principle: "pass it on."
Routing in Internet
Internet routing is the process of transmitting and routing IP packets over the Internet between two or more nodes. ... It utilizes IP-based networks, but mainly those which are publicly accessible such as that of ISPs.
Network Security
Network security is any activity designed to protect the usability and integrity of your network and data. It includes both hardware and software technologies. Effective network security manages access to the network. It targets a variety of threats and stops them from entering or spreading on your network.
Computer Graphics-Video display devices
Here we learn about some of the concepts of Computer Graphics : Video display devices Cathode Ray Tube (CRT) Horizontal deflection and vertical deflection direct the electron beam to any point on the screen Intensity knob: regulates the flow of electrons by controlling the voltage at the control grid (high voltage reduces the electron density and thus brightness) Accelerating voltage from positive coating inside screen (anode screen) or an accelerating anode Image maintenance

Computer graphics-Refresh buffer or frame buffer
Here we learn about some of the concepts of Computer Graphics : *Raster Scan Displays *Refresh buffer or frame buffer: This memory area holds the set of intensity values for all the screen points. Stored intensity values then retrieved from refresh buffer and “painted” on the screen one row (scan line) at a time *Random Scan Displays Random scan displays have higher resolution than raster systems. Vector displays product smooth line drawing. A raster system produces jagged lines that are plotted as discrete points sets.
Computer graphics-Raster Scan Systems
Here we learn about some of the concepts of Computer Graphics : Raster Scan Systems Video Controller Some of operations can be performed by the Video Controller: Refreshing operation Transformation (Areas of the screen can be enlarged, reduces, or moved during the refresh cycles) Random Scan Systems

BCA-Computer Graphics-Introduction
Here we learn about some of the concepts of Computer Graphics : Introduction Input Devices Keyboard,mouse,joystick,scanners,digital camera, bar code reader, touch Sreeen,Speech input device (microphone) Output Devices Monitor , Speaker, Printers ( different types) What’s available for input… Often used for applications with occasional use, for example Bank ATMs, Information Kiosks, etc. No extra hardware - used for input and for output Can be precise to 1 pixel Good for menu choice - not so good for other functions Intuitive to use
