...Address Class Historical Significance of the address classes: Class A: the first of the address classes, which is responsible for the value ranges of IP from 0-126 and also has 16,177,214 hosts. It also has 256 networks and the most significant bits are 0000. Class B: The second of the address classes, which is responsible for the value ranges of IP from 128-191. It also has 65,534 hosts and 65,536 networks. The most significant bits are 1000 and it is also a common class among most IP addresses. Class C: the third of the address classes, which is responsible for the value ranges of IP from 192-223 the most significant bits are 1100. It only has 254 hosts but it also has 16,177,216 networks since a lot of people have their IP addresses starting with Class D: the fourth of the address classes, which is responsible for the value ranges of IP from 224-239. Its most significant bits are 1110, and it does not have any networks or hosts because this class is rarely considered since the start of IP addresses don’t often start with 224 and above. Class E: the fifth of the address classes, which is responsible for the value ranges of IP from 240 and above. The significant bits of this class are 1111 and just as Class D does not have any hosts or networks, the same is with this class since IP addresses do not go above 192 usually. Address space A: the value range is from 0-126 so that......

...circuit-switching network is the telephone system, which links together wire segments to create a single unbroken line for each telephone call. Packet switching: Refers to protocols in which messages are divided into packets before they are sent. Each packet is then transmitted individually and can even follow different routes to its destination. Leased line: A permanent telephone connection between two points set up by a telecommunications common carrier. Typically, leased lines are used by businesses to connect geographically distant offices. Time-division multiplexing:  a type of multiplexing that combines data streams by assigning each stream a different time slot in a set. TDM repeatedly transmits a fixed sequence of time slots over a single transmission channel. T-carrier system: the name of the combination of different physical line standards(DSO, DSI, DS3 and others), plus circuits switches that use time division multiplexing (TDM) features, that together allowed the phone company to create digital circuits from end to end and create leased line services for customers. DSO: Digital Signal level 0. One of the physical line standards in the T-carrier system, as originally created by the companies of bell system in the united states. DSO runs at 64 Kbps DS1: same as above DS1 runs runs at 1.544 Mbps, with a 193-bit frame, 24 DSO channels, and an 8-Kbps overhead channel.

...increase the overall security, by reducing the attack surface that is available. One of the most vulnerable settings that can be granted to a user is local administrative access. By adding the user account to the local Administrators group, the user is granted ultimate control over their desktop. The user can perform almost any action, even if the network is configured to deny this access. Actions that a user can perform, due to them having local administrative access, include, but are not limited to, the following: remove their computer from the domain, modify any registry setting. modify permissions on any folder or file, modify any system setting, including settings that are in files in the System folder, install any application, uninstall applications, security patches, or service packs, access any website allowed by firewall, and download and install ActiveX controls, Web applications, or other malicious applications downloaded from the Internet. Although there is a need to have users running as administrator to allow certain applications to function, this type of access is very hazardous and endangers the desktop and the entire network to potential security breaches and attacks. It is essential that the local Administrator password is also reset. This is due to the fact that the user may have had administrative privileges before removing them from the local Administrators group, therefore they could have reset the Administrator account password to something they......

Network System Admin phone. The original iPhone had a 3.5 inch screen at 320 X480 and 163ppi, a quad-band 2G edge data radio, 802.1b.g Wi-Fi, Bluetooth 2.0 EDR, and a 2 megapixel camera. the iPhone was powered by an ARM-based Samsung 1176 Z-S processor and power VR MBX lite 3D graphics, 128 megabytes of random access memory(RAM), as well as four or eight gigabytes of NAND flash storage, and also could sync to iTunes. The iPhone software was very impressive, Apple used a full version of Safari, based on the exact same web kit HTML rendering engine that powered the desktop version on the Mac. Apple also created the best mobile YouTube and maps implementation ever seen on mobile. Unfortunately the original iPhone didn’t have CDMA and EVDO rev A network compatibility. That meant it couldn’t work on two of the U.S. big four carriers, Verizon and Sprint. This actually didn’t matter; because the original iPhone was exclusive to AT&T. In addition to no hardware keyboard or stylus, the iPhone also didn’t have a removable user replaceable battery, which didn’t please existing power users of the time. By 2012 Apple had released five more iPhones, 3G, 3GS, 4, 4S, and the 5. All these models offered a lot of upgrades from the first iPhone, bigger screen, more memory, better resolution, offered a white model instead of the normal black that everyone was accustomed to, not only did the phone have a camera it also had a camera on the front of the phone which no other smart phone was......

...LOCAL AREA NETWORK TECHNOLOGY Local area network technology is the technology used to make local area network to support data communication by connecting terminals, computers and printers within a small limited geographical area. Examples of LAN Technology include; Token Ring, Fibre Distributed Data Interface (FDDI) and ARCNET. Local Area Network is a data communication network connecting Terminals, Computers and Printers within a building or other geographically limited area. These devices can be connected through wired cables or wireless link. It is also a communication network for computers within a building or small group of buildings. It may be configured as; 1. A bus, a main channel to which nodes or secondary channels are connected in a branching structure. 2. A ring in which each computer is connected to two neighbouring computers to form a closed circuit. 3. A star in which each computer is linked directly to a central computer and indirectly to one another. Each of these has an advantage though a bus configuration has become the most. ETHERNET Ethernet is a standard communications protocol embedded in software and hardware devices, intended for building a local area network (LAN). It was designed by Bob Metcalfe in 1973, and through the efforts of Digital, Intel and Xerox (for which Metcalfe worked), "DIX" Ethernet became the standard model for LANs worldwide EVOLUTOIN OF ETHERNET Ethernet evolved to include higher bandwidth, improved media...

...of Samsung’s credit card business. As an outsider with deep inside knowledge, Choi took care to fit into the culture and as a result saw none of the assimilation problems that dogged many of his senior-level colleagues. He did not speak positions and, in implementing what they have learned, become important change agents. Squarely in this tradition is Samsung’s regional specialist program, arguably the company’s most important globalization effort. Each year for more than two decades, Samsung has sent some 200 talented young employees through an intensive 12week language-training course followed by one full year abroad. For the first six months, their only job is to become fluent in the language and culture and to build networks by making friends and exploring the country. In the second six months, they carry out one independent project of their choice. Initially sent mainly to developed countries, in the past 10 years they’ve gone English with his Korean colleagues. He showed full respect to subordinates older than he was. He generally behaved as other Korean employees of Samsung did. His advice to his fellow senior-level recruits is to do the same. Choi points to one of his successful protégés, whom he helped Samsung recruit in part because he knew the man would steep himself in Korean culture and be game, for instance, to eat kimchi and drink Korean wine at the dinner party given in his honor on his first day. Still, Choi is clear about......
