...Introduction: Voice over IP or VoIP is a relatively new modern way of digital voice communication that relies on many communication protocols, technologies, methodologies, and transmission techniques. The distinctive feature of VoIP is that communication happens over the internet. VoIP is a revolutionary technology that has the potential to compete with the world’s telephone systems. Some engineers have indicated that the creation of VoIP is basically a clever “reinvention of the wheel” that relates to telephone communication. Contrary to the misconception that VoIP induces, it does not deal only with voice transmission. VoIP technology can be considered a medium of transmission also for fax, SMS, voice messaging applications that are transmitted via the Internet rather than the PSTN or public switched telephone network. Some may refer to VoIP as IP telephone but these two terms are actually different since IP telephone has to do with digital telephony systems that use IP protocols for voice communication, while VoIP is actually a subset of IP telephone that transports phone calls and other type of digital information. VoIP has a relatively short history since it began spreading in 1994 as a way of communication developed by some Israeli people. Later in 1995, the first VoIP company launched on the market, "Vocaltec". By releasing an internet phone software that could be added to a computer and its peripherals while using the internet, Vocaltec's software made it possible...

...THE ART OF CYBER WAR — ASYMMETRIC PAYOFFS LEAD TO MORE SPENDING ON PROTECTION 151 As Physical Security Converges With IT Security and Becomes More Network-Based, Can Cisco Compete? Cisco recently introduced new video surveillance IP cameras and monitoring software targeted for small businesses. As corporate security technology and services become increasingly network-delivered and database-driven, the physical security market presents a compelling incremental growth opportunity for Cisco that we believe can exceed the billion dollar annual revenue threshold in the next 35 years. The physical security industry has been undergoing a paradigm shift toward convergence, whereby previously disjointed functions of IT security and physical security are experiencing greater formal cooperation. Organizations continue to implement more IP-based video surveillance cameras and building access controls both to upgrade capabilities and to reduce operational costs. Deploying IP-based security upgrades capabilities and reduces operational costs. Through the IP network a security system can assign priority to data and automatically discover new nodes such as IP cameras and control sensors, eliminating the time and effort of manual provisioning. Shifting building access controls from isolated networks to existing IP networks that house data, voice, and video can improve incident detection and assessment, authenticating both the user and device to provide efficient integrity checks. • Video...

...加拿大机械工程： 加拿大作为资源型发达国家，毗邻美国，机械工程专业在各种领域（如石油、天然气、木材、航空航天、能源、汽车等）都有颇多涉及，机械工程师一直高居各类人才需求的前5位。而作为这一行业的从业人员，毕业生需要在加拿大各省或地方的专业工程师协会登记，并经审核后获得由工程师协会颁发的专业资格证书。无论选择在国外发展还是回国效力，在发达国家积累的同行业工作经验都将是留学生的宝贵财富。 机械工程是以有关的自然科学和技术科学为理论基础，结合生产实践中的技术经验，研究和解决在开发、设计、制造、安装、运用和修理各种机械中的全部理论和实际问题的应用学科。 机械工程的服务领域广阔而多面，凡是使用机械、工具，以至能源和材料生产的部门，无不需要机械工程的服务。 【机械工程职业前景 】 就业方向：毕业生可在有关企业、科研单位、国家机关和高等院校从事机电产品设计、制造、管理、营销、科研和教学等工作。机械工程师主要在专业顾问公司、电力行业、生产及加工行业、运输行业工作。 【其雇主类型如下】 ¬ 专业服务机构(26.7%) ¬ 运输工具生产行业(11.9%) ¬ 机械制造行业(8.4%) ¬ 金属加工业(7.0%) ¬ 建筑行业(4.3%) ¬ 电力行业(4.2%) ¬ 其他制造行业(3.9%) 工程类专业作为留学热门专业，良好的就业环境和优厚的收入水平一直是这个专业的两大亮点。 【2012薪酬】 加拿大大学与雇主协会（National Association of Colleges and Employers）公布了今年春季毕业的毕业生的起薪，据统计，本科毕业生的起薪达到了55,000 左右，比去年提高了3.5%。而机械工程类专业毕业的学生遥遥领先于其他专业（如商科和管理类）达到了66,000 元，比去年上升了3.8%。 加拿大化学工程： 化学工程不同于化学专业，而且比化学专业更复杂。化学工程是将化学知识应用到了商业领域，结合了化学、工程、和生物化学三个领域的知识。化学工程专业的学生学习内容包括分子结构，设计化学反应过程（包括制造石油、食品、制药等化学过程），还需要了解原料在工厂里通过什么样的化学反应最后生成产品，也需要了解环保方面的知识，防止潜在的环境污染与生化危险。化工专业并不是一个容易学习的专业，但是就业前景不错。造纸厂、化肥厂、制药公司、塑料制品厂、石油制造行业都需要化工专业毕业生。就业：市场需求很大，化工在工程类专业中需求量排第3位，也是工程类专业中收入最高的专业。毕业生还可以选择其他的工程专业，进行深造，或者可以进入法学院和医学院学习。 加拿大化学工程专业2011年排名： 1. 多伦多大学 2. 麦吉尔大学 3. UBC 4. 麦克马斯特大学 5. 皇后大学 6. 阿尔伯塔大学 7. 滑铁卢大学 8. 卡尔加里大学 9. 曼尼托巴大学 10. 渥太华大学 加拿大材料工程： 材料是用于制造有用物件的物质。材料科技是电子、信息、通讯、航天、机械及光电产业的基础。因此，材料被称为「工业之母」。根据材料的组成结构，可分成金属材料、无机非金属材料、高分子材料和复合材料；根据材料的性能特征，可分成结构材料和功能材料。当今，人们把材料、信息、能源作为现代文明的三大支柱。新材料技术更成为三大高新技术之一。 ...
