Abstract—
GSM bears numerous security vulnerabilities.
Although GSM’s architecture is designed in such a way to
provide various security features like authentication, data/
signaling confidentiality, and secrecy of a user yet the GSM
channel is susceptible to replay, interleaving and man-in-themiddle
attacks.
The GSM speech service is secure up to the point where speech
enters the core network. However to achieve end-to-end security
it is desired that the GSM subscriber, not the network operator
controls the encryption on ....etc

Supernetting and Classless Addressing



Supernetting

Classes A and B are almost depleted.
Class C addresses are still available.

What if a company needs a network larger than 254 hosts?

! Give the company several consecutive blocks
of C addresses and treat these as a single supernetwork


Rules:

The number of blocks must be a power of 2

The blocks must be contiguous in the address
space (no gaps between the blocks).

The third byt ....etc

Abstract
This paper presents a novel parallel addressingscheme for voltage-programmed active-matrix organic lightemittingdiode (OLED) displays which provides high precisionrecovery of the threshold voltage shift. As a result, the uniformityover the panel is significantly improved. In addition, a new pixelcircuit is presented that is capable of providing a predictablyhigher current as the pixel ages, so as to compensate for the OLEDluminance degradation.Index Terms—Active-matrix organic light-emitting diode(AMOLED), hydrogenated amorp ....etc

IP Addresses:Classful Addressing
RULE:
If a protocol uses N bits to define an address, the address space is 2N because each bit can have two different values (0 and 1)and N bits can have 2N values
Network Addresses
The network address is the first address
The network address defines the network to the rest of the Internet
Given the network address, we can find the class of the address, the block, and the range of the addresses in the block
In classful addressing, the network address (the first address i ....etc

Understanding IP Addressing


Understanding IP Addressing:

Everything You Ever Wanted To Know
The Internet continues to grow at a phenomenal rate. This is reflected in
the tremendous popularity of the World Wide Web (WWW), the opportunities
that businesses see in reaching customers from virtual storefronts,
and the emergence of new ways of doing business. It is clear that expanding
business and public awareness will continue to increase demand for access

Efficient Addressing


How to Make Routing Scale



Flat (Ethernet) versus Hierarchical (Internet) Addresses
-All hosts attached to same network have same network address
Problem: inefficient use of Hierarchical Address Space
-class C with 2 hosts (2/255 = 0.78% efficient)
- class B with 256 hosts (256/65535 = 0.39% efficient)
Problem: still Too Many Networks
- routing tables do not scale
-Big tables make routers expensive
-route p ....etc
