...1. Why we need Computers and what’s its importance? 1.1 Computers help us in saving our work without losing any data. Computer memory is technically any type of electronic storage. And without this electronic storage, the computer has no benefit from startup to shut down, and all processes in between, a computer relies on several types of memory in order to function. There are two types of memory that we use in the computer: Primary and Secondary memories. Primary memory which is the main storage stores all the data that we use in the computer, such as Hard disk drive. And the secondary data is the data that stores programs, such as: RAM (Random Access Memory). The difference between them that the secondary memory is deleted after the computer was turned off while the primary memory remains without losing any data. The computer stores the data in form of binary numbers. For example, letters are converted to...

...1. What is data? Data is often information set of values mainly in text or electronic strings of 0’s and 1’s formatted in a special way to suit the data system or operating software used which manipulates the data into a set of instructions that exist in many forms in paper or electronic bits and bytes that are saved in electronic memory. 2. Write a list of the kinds of data that we can save, store, organise and return and retrieve with music technology. There are many kinds of data that can be used in music technology and comes in different formats like .WAV .AIFF which are uncompressed audio formats used as samples or loop files within DAW software, Also MIDI formats are used for generating powerful sounds from a basic control signal that can be put directly into a digital sound environment, all these sounds can be arranged, edited and organised well within music technology software today. 3....

...Window Server 2008-DCHP Server Role This paper is designed to explain the equipment, installation, and configurations of the DHCP Server Role for Windows Server 2008. In order to fully understand how DHCP Server Roles operate within the network, you first have to know why, when, and where the DHCP Server Role will be used. What is a server role? A set of software programs that when installed and configured properly, allows a computer to perform specialized functions for numerous clients or other computers within a network. They describe the main function, or use of a computer. A certain computer can be created to perform a clear-cut function that’s greatly used in an enterprise, or perform many roles if it’s not used too much. They provide aid to client’s throughout an organization, that’s directed by other computers, like websites, printers, or files. They usually include their own databases that queues client’s and computer requests. As soon as the server role is installed and configured correctly, it functions automatically and begins immediately. Once a role has been established, the role can perform a service, and that service is the functionality of a role. When you install a role, you can choose which services that role will provide for users or computers. Choosing a DNS Server will only provide one service, but something like Remote Desktop has many services that can be installed. The server role that we want to discuss in further detail is the DHCP Server Role. So...

...To choose an appropriate system, we should determine which system meets the needs of our practice as well as legal and regulatory requirements of our jurisdiction. We should also determine how the chosen system will work in concert with other electronic records systems. We must know the compatibility requirements as may be prescribed by the health authorities, health facilities or clinics. To facilitate this choice, there are various professional resources, including technology providers, consultants Information Technology, provincial, territorial or national medical associations and local technical support programs for doctors. Colleagues who have implemented an EHR system can also provide useful information. Some organizations of a province or territory have a list of pre-approved suppliers that facilitates the selection process and can also offer subsidies to offset part or all of the costs of acquisition and implementation. The system vendor will likely require that we sign a license to use the software, which is a legal agreement governing the use and distribution of EHR software protected by copyright. Although they give to a physician or group of physicians to use the software, user licenses also impose certain obligations and restrictions on the use of the product. Before signing such agreements, we should know the clauses. By implementing an electronic file system in a medical office, internal policies must be established to deal with issues such as data integrity, consent...

...NT1330-Unit 2 Exercise 1 DNS Scenario Dear junior IT, Thank you for contacting me regarding your questions, and trust that I will do my best to help you. From what I understand, you work at two branch offices, and have been given the responsibility of discovering where to place an Active-Directory Integrated DNS server. You also have some question of what type DNS server would best meet your company’s needs. First let’s begin with the smaller branch supporting perhaps five user/workstations, with an unusually slow network. The question with such a small branch isn’t really about what kind of DNS server you need, but do you need a DNS server at all. If there is a very high level of file/data sharing, then yes perhaps you could benefit from a server, but configured in a secondary zone, such as an ADI. However, if there is not enough file/data sharing to really warrant the presence of the server, an ADI server could potentially slow down an already sluggish system. Now let’s move on to the second, much larger branch supporting around thirty users. You stated that this branch has a much better network connectivity than its smaller counterpart. In this case, I would recommend a DNS server set up in the primary zone. The primary zone is the primary source of information within this zone. I would also further suggest moving your servers from the smaller branch to your larger branch. All files from the smaller branch could be accessed via a “VPN” remote link. This would allow...

...NT1330 Unit 4 Assignment 1. AD Design Replication Scenario AD Design Replication Scenario To whom it may concern: I am the IT Administrator for the company and I have been asked to give my recommendations for the Active Directory Replication Design of the two new Branches. The first I can recommend for you is that all the information that is needed for each new site is correctly documented and added to the Root Active Directory through the Active Directory sites and services. This is done because the Root AD automatically builds the inter-site replication topology based on the information provided about the new site connections. Each new site’s AD will have one each domain controller that is known as the inter-site topology generator and they are assigned to build the topology at their sites. To add two new branch offices we will need to find a strategy to design a replication process. To implement this we will need to use inter-site replication. Inter-site replication is needed when adding domain controllers located in different sites. We will also need a site link (Site link is a logical, transitive connection between two sites that allows replication to occur) protocol of Remote Procedure Call (RPC) over Internet Protocol (IP) which is the preferred choice for the replication process. This allows you to communicate with network services on various computers and also keep data secure when being transmitted by using both encryption and authentication...

...The main purpose of the Lab 1 was to install, configure and test Amazon Web Service Virtual Private Cloud by launching an Ubuntu Linux instance to see if it connects. The lab started with a scenario where I am a newly hired IT guy at Flux Unlimited with my first task to set up and test the company’s network infrastructure using Amazon Web Services to provide the perfect cloud based solution that they need. This starts with setting up of a VPC which is a virtual network dedicated to AWS and it is logically isolated from other virtual networks in the AWS cloud. Next after this is selection of right region with at least two Available Zones (data center) in each region. The AZs in each region helps to provide redundancy in case there is an outage in any of the available AZ. After creating a VPC, a public subnet named FluxPublicSubnet was...

... Be Organised: Check that I have enough time available to devote to the task and will have no distractions in this time. Make sure that I have all learning material at hand and within easy reach of my seat. Be comfortable sitting and have the computer at a comfortable and ergonomic position. Check that wifi connected and have enough 'access' time to complete the task to be worked on. Go to the toilet to eliminate that distraction and make myself a cup of coffee to have while I am reading learning material. 2. Reading: Read the appropriate material at least twice, taking notes to points that I feel will be important to remember. I like to have quiet while I am reading, although this is not essential just a preference. I will read material a number of times until I think I have a good understanding of what is being said. I sometimes read out aloud if I am having trouble understanding something and that is probably why it is a good idea that I am alone. I try to understand a concept before I move onto the next step, rather than flyby the seat of my pants. 3. Minimise distractions: Keep the environment as noise free and distraction free as possible. Allocate the time for studying when there will be less distractions around me, so keeping aware of other peoples comings and goings in the household to be able to use the time home alone whenever I can. Ignore the door and phone as much as possible, to the point of rudeness sometimes. Do not access e-mails until after study time is complete...

...In this project, I learned a lot of things both on the dataset and on data visualization through my contribution to the project. The works in both the first and second stages of the project were divided equally and efficiently among the three group members. For the stage 1 of the project, we first met together to brainstorm all of our ideas, find an interesting dataset to be used for the next parts and divide all the work load equally. One other group member and me contributed to the database design using star schema and the planning of data visualization in the second stage. Furthermore, in the second stage of the project, through a group meeting, we again divided the work equally among the three of us and discussed the visualization types that we are going to use for our data. To make it equals, each member chose one type of visualization method to discuss in the report. In this part, I did the part to whole visualization method, where I used it to visualize two important data of the dataset through a...
