IT-management overhead in reference to DNS and DHCP In order to address the issue of when is it cost effective to employ the use of DHCP for a computer network we first have to get a brief understanding of the terms DNS and DHCP. Domain Name Servers (DNS) for short is like a phone directory for the internet. They translate domain names into IP (Internet Protocol) addresses. Domain names are easier for people to remember, computers access the internet based on IP addresses. Dynamic Host Configuration Protocol (DHCP) is a network protocol that allows a server to automatically assign an IP address to a computer. Now that we have defined these two terms it is possible to analyze the cost effectiveness of a DHCP server. To manually configure a computer workstation with an IP address is not difficult. On the other hand to manually configure tens, hundreds, or thousands of workstations would be too time consuming, it also increases the chance of duplicating IP addresses, misconfiguring the subnet mask or other network protocols. It is in these instances that DHCP is not only a handy tool it is a needed tool for network administrators to perform their job. There are three main instances to manually assign addresses. 1) When there are no configured DHCP servers on the network and the network has multiple network segments. 2) When you are configuring a computer as a DHCP server, you assign that computer a static IP address. 3) When you configure computers as important network servers such as domain controllers, or DNS servers; you manually assign the IP address to these computers. By understanding that time is money the three main reasons to manually assign addresses it is easy to determine when to employ DHCP. The use of DHCP is not necessarily needed for a small network of 2 to 10 computers but it would allow a company the room to grow their network as needed.

...Unit 1 Assignment 1 1. Describe the role of software for computers: Computer software tells the hardware what to do. Without any software, the hardware would be worthless. Think of the software as a subject in school, and the hardware as you or your brain. Without any learning, you can't do anything. One you have learned some math, and then you are able to solve math problems. This learning is usually accomplished through downloads or CD's that are loaded into the computer. At the very basic level, computer software contains specific instructions for how to accomplish a specific task. These instructions tell the hardware exactly what to do, and how to do it 2. Identify the hardware associate with a computer: the physical components that make up a computer system. There are many different kinds of hardware that can be installed inside, and connected to the outside, of a computer. Here are some common individual computer hardware components that you'll often find inside a modern computer case: Motherboard, Central Processing Unit (CPU), Random Access Memory (RAM), Power Supply Video Card, Hard Drive (HDD), Solid-State Drive (SSD), Optical Drive (e.g. BD/DVD/CD drive) Card Reader (SD/SDHC, CF), etc. Here is some common hardware that you might find connected to the outside of a computer: Monitor, Keyboard, and Mouse 3.

...Unit 1 Assignment 1 Integrated Circuit Technology A motherboard is the backbone of the personal computer, it transfers information and power to all the other components. The motherboard is the largest board inside of the computer that contains the basic input and output system that allows every component to communicate with one another. Attached to the motherboard is a chip comprised with dozens of pins called the central processing unit. Along with the CPU attached to the motherboard is the dual-inline memory modules a part of the random access memory. RAM is the most common type of memory used another type is ROM, read only memory, which stores data onto metal disc within the device. The operating system manages the hardware resources and provides a place to run programs. The last components of the personal computer are the tower and the human interface devices. The tower holds all the components that make up the computer except for the HID which are located outside of the computers tower. The main purpose of the HID’s are to help us interact with the computer, a few examples are the keyboard, mouse, monitor, video camera and speakers. You put together the Motherboard, CPU, RAM, ROM, OS, Tower, HID’s add a power supply and you have a basic personal computer.

You can identify hypertension if your blood pressure is higher than 140 over 90 mmHg. While having hypertension you could also develop some other conditions such as kidney disease. Even though hypertension itself does not cause symptoms, it does lead into long-term complications caused by blood vessels becoming narrower. To be able to reduce Hypertension and get better, we would need to cut down, restrictions such as salt restriction; moderation of alcohol and other diet changes that have affect your condition you have now. There are several drugs that may be used for treatment. Hypertension will affect your heart, so your blood pressure should be normal… when you follow the restrictions. Diabetes Is also called diabetes mellitus, what it does is describes a group of metabolic diseases in where you have high blood glucose, which is high blood sugar.

...Unit 1 Assignment 1 Cell Phones use voice and data communications. It uses the voice at a lot less these days because people rarely call one another anymore. Data is used for the applications which people use more of these days. So they use a mixture of both but mainly data. Also some phone now use Wi-Fi calling so people can use data networks to call people. Landlines use voice communication. Unlike data voice can work during a black-out because it doesn’t get its power from the same and everything in your house. It’s also a cheaper technology which also makes it cheaper. SMS/Text Messaging uses data. It’s part of the reason I said Cell Phones use both. And it can only be sent over 2G and above because 1G is voice only. Fax Machines use voice. It uses the same jack and RJ-11 like landlines do. It can be used on data but traditional fax use the voice network. The fax is sent it immediately gets digitized the put back in analog form once its sent. Pagers use data. It’s almost like SMS in the is send data (words over the networks). It’s an older technology. VOIP phone use data. It’s similar to Wi-Fi calling. It breaks up in to packets and is sent over the air waves. If you used a VOIP phone you could probably hear it sounding choppy that’s because those packets were dropped for some reason or another. Skype and face time also use data. Without internet connection these applications can’t be used. The main reason these applications exist it to provide an alternative...

...Tina Nunez NT1330 Unit 1. Assignment 1 Windows 2008 Network Services Domain name system (DNS) is a naming service used on any device that can connect to the internet. It translates fully qualified domain names of websites into IP addresses for the device. There are DNS records such as address (A, AAAA) records, name server (NS) records and mail exchanger (MX) records stored in the DNS server. Regardless of how many hosts, the DNS is a system that is very important. Dynamic host configuration protocol (DHCP) is a networking protocol that allows the dynamic (automatic) distribution of IP addresses to hosts on a network. If DHCP is enabled, the hosts will each receive a leased IP address that is chosen by the DHCP server from a scope chosen by the network administrators. Sometimes the administrators can reserve IP addresses if needed. Depending on the amount of hosts, it could determine if the IT management wants to use DHCP. If the company is very small, it may not be worth the effort to set up a DHCP server. It can still work but static (manual) IP addresses would be simple to configure because there would be very few devices compared to a large company. Some of the vital devices will usually use static IP addresses anyway such as any servers. If there is a very large company, it would be extremely beneficial to use DHCP. All of the devices can automatically pick up an IP as soon as they connect to the network and the network administrators do not have to go to each and...

...Unit 1 Assignment 1 AP2530 Hypertension Hypertension is just a fancy medical term for high blood pressure or HBP. When your heart beats, it creates pressure that pushes blood through a network of tube-shaped arteries and veins around your body. When we measure this pressure it is referred to as “blood pressure”. This pressure is the result of two forces from the heart. The first force occurs as blood pumps out of the heart and into the arteries. This is the top number in the reading called the systolic pressure. The second force is created as the heart rests and refills with blood between beats, and is called the diastolic pressure. The average person will have a blood pressure reading of about 120/80. Any reading where the numbers are higher than that is considered to be high. The arteries in your body are made of muscle and a semi-flexible tissue that stretches like elastic when the heart pumps blood through them. The more forcefully that blood pumps, the more your arteries have to stretch to allow blood to flow easily, and when the force of the blood flow is to high on a regular basis, the tissue that makes up the walls of your arteries gets stretched out. When left untreated this creates problems and damage over time. The overstretching creates weak places in the blood vessels, making them more likely to rupture or break. Also, the overstretching can cause tiny tears in the blood vessels that leave scar tissue on the walls of arteries and veins. These tears and the...

...Unit 1 Assignment 1 Scientific inquiry is a process of developing an explanation of a question by testing, investigating and collecting data that will either support the idea of what's going on. A problem in the world can be a scientific inquiry because you might have a question about it, so you are basically digging for information about the problem going on and you try to find results by using the internet, books or any source to get your answers. There will be results maybe through testing or charts will appear from studies to support the answers. A non-scientific inquiry is one that does not use a systematic collection of evidence or one that tries to find answers to questions about things other than the natural world/universe, such as beliefs. An example of everyday assumption is gender or stereotyping of what you see that what you assume this more like expectations. If women are mowing the lawn there is going to be a man that will approach you and tell you how to do things properly or what to wear in order to for you to cut the grass right. The answers will come to you without seeking them, just because she is a women it doesn’t mean that she don’t know what’s she doing it is just an assumption because of her gender.

It is also described as having a feeling of fellowship with others, as a result of sharing common attitudes, interests, and goals. Community groups are created for a lot of different reasons some more critical than others. Since communities are so close knit people start groups for several reasons, the most common is just to know one another and be familiar with who you live by. Some people start neighborhood watches, borrow things from one another or just simply look out for each other when the other is not at home. What Makes a Good Community? In my personal opinion a Good Community takes time to form. Just like anything school, work, etc... You’re taking different people from different places, ethnicities, and backgrounds and putting them all together in once specific place. So it takes time for everyone to gel, but in all it takes patience, understanding and just being courteous and respectful. Challenges There are a lot of challenges you face when your living somewhere whether it’s a bigger or smaller community, it may possibly be easier to get know everyone in a smaller community than a bigger one. For instance some communities or neighborhoods are outside the county that means that the city does not fund the neighborhoods street lights, therefore the community have...
