Yes, Jeff did a great job and performed as I expected him to. He was very welcoming when I joined CapTech. Any questions I went to him with he was able to answer and if he wasn’t he made sure to point me in the right direction to get an answer.

The network administrator (or "network admin") is usually the level of technical/network staff in an organization and will rarely be involved with direct user support. The network administrator will concentrate on the overall integrity of the network, server deployment, security, and ensuring that the network connectivity throughout a company's LAN/WAN infrastructure is on par with technical considerations at the network level of an organization's hierarchy. Network administrators are considered tier 3 support personnel that only work on break/fix issues that could not be resolved at the tier 1 (helpdesk) or tier 2 (desktop/network technician) levels. Depending on the company, the Network Administrator may also design and deploy networks.

Network, Systems, Database, and Application Administrators: Those individuals responsible for the maintenance of systems and networks. It is their responsibility to implement defensive mitigations during and after an incident, and to clean up affected systems. A firewall/IPS administrator might be responsible for closing the entry or egress points being used by the

Computer Support Specialists can fall under many different categories with the common factors being that they give advice and help to end users and organizations on computers, equipment, software, computer access, and networks. The main emphasis is that we will be working with end users to ensure that they are capable of doing their job on a networked system. As a computer support specialist you will have to be trained for operating systems, software, networks and hardware in order to be capable of assisting end users to a solution or so that you can explain the situation to a higher level to get the proper support for the situation.

As the IT Industry has recorded prodigious growth over the past ten years, the role of the Chief Information Officer (CIO) has become a daunting job because of the heaping business and technological responsibilities assigned to the organizations. CIO’s are enforced to successfully ensure the firms Information Systems (IS) investments as they frequently regulate with its decisive business goals, while also planning and maintaining IT infrastructure that will meet the firms present and forthcoming information processing needs. Many CIO’s are finding it strikingly difficult to balance the key roles of technician and business person successfully. This paper also describes the responsibilities and challenges that should be maintained and faced by the CIO (Robert C Beatty, Kirk P. Arnett & Chang Lui, 2005).

These applications involve a wide range of features considering its complexity. Main features electronic medical records, telehealth, telemedicine, mHealth, eLearning and interoperability.

Despite recent progress in information technology, health care institutions are constantly confronted with the need to adapt to the resulting new processes of information management and use.[1] Nusing information systems(INSs) are promoted as a technology supporting collaboration and improving health care decision making at the point- of –care and ultimately health care outcomes. An NIS contains data collection and intetration functionality for nurses and could be used as a part of an electronic health record(EHR) or in conjunction with an electronic medical record(EMR). NISs have the potential to increase nursing documentation completeness readability, and availability. NISs also provide the means to decrease double

In order to perform a variance analysis report Jenkins calculated the actual revenues and expenses and found the difference which was $296,610 in profits. Then Jenkins did the same with budgeted values and found the budgeted profits to be $606,350. The variance amount in turn is $309,960 under budget. Also, the variance amount for revenues is $32,100. This number is favorable due to the fact that they made more than what they had budgeted for. But on the contrary, the variance amount for expenses was $342,060, which was unfavorable because they spent far more than what they had budgeted for.

Convergence – In the telecommunications industry, convergence refers to the integration of voice, internet, broadcasting, and other telephony servers into one mega-industry from their traditionally separate industries. Companies such as Telstra are an excellent example of this, as Telstra now offers an abundance of products such as, Fixed Phone, Mobile Phone, Dialup Internet, Broadband Internet, Wireless Internet, TV, Music, Tickets, and more. Incentives are given to “bundle” services with the one particular provider, which can have advantages and disadvantages.

In the early 1990s, the Florida Department of Management Services (DMS) had built up a large information systems network that served state government agencies in 10 regional sites and connected these to the data center in Tallahassee. The network was based on the use of the proprietary Systems Network Architecture (SNA) from IBM and a mainframe at the data center that housed most of the applications.

After two labs focusing purely on the Linux side of systems administration and network services, this third lab puts Windows into the spotlight and how it deals with configuring services as compared to the previous RHEL-based configurations. Many of the same tasks which were completed using a RHEL 7 virtual machine in lab 2, such as setting up DHCP and DNS, are repeated in this lab on a Windows 2012 Datacenter virtual machine. This is done not only to show the differences in service administration, but also to indirectly teach students the steps as well as precautions that need to be taken when integrating in different enterprise server operating system families which very well could be running the same network services, such as in the case of this lab. Instead of merely just installing the same services and letting the clients make decisions on what data to receive from who, this lab also presents the challenge of making these two very different operating systems work together when the time comes to configure the DNS server on the Windows VM. A major point I took away from this is that while the Microsoft and ISC implementation of a DNS server can be seen as widely different, the integration of the two is very smooth and easy due to both of them still following the base rules of the DNS protocol as well as framework found in the numerous RFC’s which describe it. Active Directory, which is also installed on the server, was review at this point from multiple different
