Knowledge in Computer Architecture
Instruction Set & Addressing
The addressing mode specifies a rule for interpreting or modifying the address field of the instruction before the operand is actually executed. The 8086 memory addressing modes provide flexible access to memory, allowing you to easily access variables, arrays, records, pointers, and other complex data types.

Noise Performance of Various Modulation Schemes
Why modulation is used in communication? In modulation technique, the message signal frequency is raised to a range so that it is more useful for transmission. ... In signal transmission, the signals from various sources are transmitted through a common channel simultaneously by using multiplexers.
Information Theory & Coding
nformation theory studies the quantification, storage, and communication of information. It was originally proposed by Claude Shannon in 1948 to find fundamental limits on signal processing and communication operations such as data compression, in a landmark paper titled "A Mathematical Theory of Communication".
Architecture of Micro controllers
Microcontroller. A microcontroller is essentially a small computer on a chip. Like any computer, it has memory, and can be programmed to do calculations, receive input, and generate output. Unlike a PC, it incorporates memory, a CPU, peripherals and I/O interfaces into a single chip.
Models of Computation
A model describes how units of computations, memories, and communications are organized. The computational complexity of an algorithm can be measured given a model of computation.
NP Copmleteness and Approximation Algorithms
In computational complexity theory, a problem is NP-complete when it can be solved by a restricted class of brute force search algorithms and it can be used to simulate any other problem with a similar algorithm. ... If any NP-complete problem has a polynomial time algorithm, all problems in NP do.
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.
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.
