...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...

...NT1330 Mr. Ajero Assignment 1 September 14, 2015 DNS – Domain Name System DNS is a hierarchical representation of all the IT devices and their sub-domains in a (company) network. So, in case you see an address like mail.subdomain.company.com, you can easily recognize the name of the system (mail), name of the sub-domain (sub-domain), name of the company (company) and the name of the primary domain (.com). DHCP – Dynamic Host Control Protocol A DHCP server automatically assigns the IP addresses for a device. Any device, before communicating with any other device in the network needs an IP address. These IP addresses are given to the network devices dynamically by a DHCP server (IP addresses ought to be within a certain range and the range is already specified). The IP addresses assigned this way are not permanent – they are actually leased for a certain amount of time to the devices (till they log-out of the network, for example). I believe that two hosts should be sufficient. Using a DHCP Relay Agent would greatly reduce the time necessary for me to set up the name allocation and resolution. If I were to do this manually on a static IP Address, I would have to put a stop to it at 25 machines as it would waste valuable time with trying to get to the other pieces of equipment my client owns. Regardless of if I was getting paid by the hour, I would need extra time for future maintenance and upgrades References DNS and DCHP explanation/definition:...

...EN1330 Client-Server Networking 2 Unit 1. Assignment 1 9/25/2014 A Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resources connected to the internet or a private network. It associates various information with domain names assigned to each of the participating entitles. It translates easily memorized domain names to the numerical IP addresses needed for the purpose of locating computer services and devices worldwide. The best way that I have been able to explain it, it works like a phone book for the internet by translating hostnames into IP addresses. But unlike a phone book, the DNS can easily be updated and quickly. The internet maintains two principal namespaces, the domain name hierarchy and the Internet Protocol address spaces. A DNS name server is a server that stores the DNS records for a domain name, such as (A or AAA) records, name server records, and mail exchanger records. A DNS name server responds with answers to queries against its database. The Dynamic Host Configuration Protocol is a Standardized networking protocol used in Internet Protocol networks for dynamically distributing network configuration parameters, such as IP addresses for interface and services. With DHCP computers request IP addresses and networking parameters automatically from a DHCP server, reducing the need for a network administrator or a user to configure these settings manually. DHCP is used by computers for requesting Internet...

...At ADSD, the database administrator (DBA) is responsible for the performance, integrity and security of the container databases including the root, the PDB seed and the user-developed pluggable databases. The DBAs should also be intrinsically involved in the planning, development, testing and deployment of the database consolidation initiative. 1.4.2.6.1 Responsibilities • Installation, configuration, upgrades, and consolidation: Although system administrators are typically responsible for the hardware and operating system on a given server, installation and configuration of the database software is typically done by the DBA. The DBA should possess knowledge of the hardware prerequisites and requirements for a high-performing database server. The DBA installs the database software and configures it for the purpose it is intended for use. As new releases and patches are developed, the DBA decides on the appropriate patches, tests them on a test server that replicates the production server and then installs them on the production server. If a new server is commissioned to replace an old one, then the DBA migrates the database from the old server into the newly commissioned server. Automating server provisioning is the responsibility of the DBA also. With automated provisioning, consistency in the installed and configured servers is maintained. Additionally, several servers can be commissioned at the same time instead of one at a time if done manually. Hence, automated provisioning...
