CPU (Central Processing Unit) which is the brains of the computer where most calculations take place. In terms of computing power‚ processor is the most important element of a computer system. Without it‚ a computer cannot even boot up or running. The performance of processors determines the speed and the performance of the notebook as well. Whether a computer system can run smooth or not is also depend on the performance of processor. Most of the processors of notebooks can be divided into two

for upstream and downstream data transmission on the same conductors‚ which is also an example of frequency duplex. Where frequency-division multiplexing is used as to allow multiple users to share a physical communications channel‚ it is called frequency-division multiple access (FDMA). FDMA is the traditional way of separating radio signals from different transmitters. In the 1860s and 70s‚ several inventors attempted FDM under the names of Acoustic telegraphy and Harmonic telegraphy. Practical FDM was only achieved in

ISO-OSI 7-Layer Network Architecture This lecture introduces the ISO-OSI layered architecture of Networks. According to the ISO standards‚ networks have been divided into 7 layers depending on the complexity of the functionality each of these layers provide. The detailed description of each of these layers is given in the notes below. We will first list the layers as defined by the standard in the increasing order of function complexity: 1. Physical Layer 2. Data Link Layer 3. Network Layer 4.
