Further, current trends in total health care expenditure are expected to reach 20% of the Gross Domestic Product (GDP) in 2022, which is a big threat to the W lenges [1, 2]: demographic peak of baby boomers, US economy. Moreover, the overall health care expenditures in increase of life expectancy leading to aging

As Chief Information Officer (CIO) of a small but growing firm, the organization is outgrowing the current architectural centralized telecommunication structure along with the computer networks. The task at hand is to protect the valuable information, but remain flexible enough for employees to perform their daily duties. The enhancements need to address security aspects such as remote data access, enterprise mobility, and internal communications such as email. When accommodating a growing organization

intertwined, as you have to be able to work in a team of specialists, programmers, and be able to direct them on what they have to do. [6] An additional career choice would be a networking technician. They help a company to install wide area networks, and local area networks data communication equipment. A networking technician also helps to fix and analyze problems reported by the players of the MMO game. To ensure that customer satisfaction is sufficient enough, technicians usually help to maintain

policies and physical security to derail these problems. The second domain is the workstation domain. The threats to this would be similar to the first domain because if a user does something malicious on that workstation, it would affect a larger area of the domain. Another problem is that workstations run programs that are susceptible to bugs and crashes. If

1. Case Study It’s a project on WAN network design for a company which is five year old and have multiple branches. It’s a IT& Electronics company located in Auckland named eServe. I am working for this company from last six months as a IT technician. The company have multiple branches in other cities as well. They provide software and hardware related services to their clients and mainly concern with apple (Mac Book, iMac, phone) products. The company have three branches in wellington, Christchurch

Bridge: Bridge is a simple device that aids in interconnecting similar LAN's between local area networks that use identical protocols for the physical and data link layers in accordance with the IEEE 802.3 standards. As the devices connected to the bridge use the same protocols, the amount of processing required is minimal. Nowadays, routers are used more commonly to interconnect LAN’s as bridges are Layer 2 devices and pose almost no security while the router is a Layer 3 device and offers better

RS-422: RS-422 ,also known as TIA/EIA-422 is a technical standard originated by Electronic Industries Alliance that specifies electrical characteristics of a digital signaling circuit.It is the physical interface used for uni-directional or bi-directional communication of OBC of PNSS-1 with different units i-e DHU(data handling unit),MGT,earth sensor,sun sensor,magnetorquer,magnetometer and with reaction wheels.It is serial communication standard which provides asynchronous communication capabilities
