In some cases, mini twists are so small that the hair may appear loose rather than twisted. THE GOOD: Mini twists last longer — anywhere from three to six weeks — than larger twists. Because they are so small, they tend not to frizz and age as quickly. This is great news for those who want to leave their natural hair alone for several weeks at a time. Not only do mini twists last longer, they also allow for more versatility in styling. Because they are so small, it is much easier to achieve a range of styles than with larger twists. A lot of the styles can mimic those on loose natural hair. minitwist1 (In 2013) THE NOT SO GREAT: Mini twists can take hours to a day or two to install or take down. This can be a challenge if you have to be somewhere or you just do not have the time or patience. In terms of helping with patience, watching a few movies or television shows can help pass the time. When it comes to needing to be somewhere, some naturals prefer to start...

...Name: Shelly (Yiru) Shi Year: 10th Title: Speak Author: Laurie Halse Anderson The book, “Speak” by Laurie Hales Anderson is about Melinda has a deep secret in her heart which she was raped by a boy named Andy. It is too shameful and secretive for her to talk. I have a friend who was raped by her half brother, but she chose to talk to the Elders eventually. There is an old saying in Chinese that “you should turn on the light in your heart by yourself. Thus nobody can save you except you at the first time”. I feel for her because as for me sometimes when I feel that something’s are hard for other people to understand I tend not to talk about because nobody can understand. For Melinda, sex is one of the most important things in a woman’s life. Nobody wanted to ask her what happened at first time when her best friend Rachel or her mom saw her weird behavior, but also her fear and struggling in her deep heart. She needs somebody to push her, to help her in a gentle way, like Mr. Freeman did. Even though, I didn’t meet any of these things in my life, it doesn’t mean it won’t happen in somewhere else in the whole world. Before I read the book, I thought if someone doesn’t want to talk, it just because they are introverted by nature. I always adopt a nonchalant attitude towards things of no personal interest (which is a Chinese old saying). But I realize that there would be lots of people that we need to focus on. Maybe they are sadness ladies, upset students or even autistic...

...The Benefits of Twisted Pair Cable Introduction to Networking October 29, 2013 Ocper Inc. is a small company that has no one dedicated to information technology or networking on the staff, and there are 20 Windows peer-to-peer client computers all connected via coax cabling. The president has indicated that the company plans to double in size over the next two years, but she is weary of drastically changing the computing environment. This is my first assignment, but I feel that I have a very good plan to help give them a faster, more secure, and efficient network. The first change that I would recommend would be to move away from a peer-to-peer network to a client/server network. I would explain that there are many advantages to switching to a client/server network such as (Dean, 2009): * User logon accounts and passwords for anyone on a server-based network can be assigned in one place. * Access to multiple shared resources (such as data files or printers) can be centrally granted to a single user or groups of users. * Problems on the network can be monitored, diagnosed, and often fixed from one location. * Servers are optimized to handle heavy processing loads and dedicated to handling requests from clients, enabling faster response time. * Because of their efficient processing and larger disk storage, servers can connect more than a handful of computers on a network. The advantages of a client/server far outweigh any possible disadvantages. ...

...select two backbone configurations and discuss which one you think is the better option for networks of today. Indicate why you think that planning an enterprise-level backbone can be such a challenging process. I think before going into details, we should understand what is backbone. After a lot of research, I came up this definition; a backbone is a means of connecting two or more LANs. It provides a transmission channel for packets being transmitted from one LAN to another. After connection to a backbone, a LAN may remain distinct or be merged with another. Backbone networks can be applied to a single building environment as well as to campus environments, where the backbone is used to connect LANs in different buildings. Parallel backbone: I think parallel back is the best worth it for any company. The additional cost of setting up a parallel backbone can be well worth the money. The design of this type of backbone consists of using two cables routed between the routers and switches. While there are additional initial costs of installing a parallel backbone, the benefits can quickly outweigh these costs. However if company wants to save some money, they can use distribute network. It consists of a number of connectivity devices connected to a series of central connectivity devices, such as hubs, switches, or routers, in a hierarchy. This kind of topology allows for simple expansion and limited capital outlay for growth, because more layers of devices can be added...

...The Benefits of Twisted Pair The Benefits of Twisted Pair The current topology appears to be a bus topology. Everything is connected via coaxial cable and is referred to as passive, meaning that each computer on the network “listens” for data to pass by with its name. While this type of topology will suffice for small networks, it is not ideal for the current network at Ocper, inc. Another downside of the current topology is lag. While the network is small you may not notice the lag, or just assume the network is supposed to run this slow. Using coaxial cable as a network data path limits the amount of bandwidth available as well as the ability for two-way data flow. My recommendation would be to convert to twisted pair cabling. The twisted pair cable will allow you a larger bandwidth which in turn allows more computers to send more data across the network. Twisted pair will also allow two-way data flow, allowing for data to pass back and forth more effectively by “sharing” the bandwidth. For these reasons, twisted pair will allow you to transfer vital information back and forth across the network much more quickly, making the customer wait less. I would also recommend changing the topology to a star-wired Bus. A star-wired bus will allow you to isolate segments of your network and span it over greater distances. Isolating a segment of the network will allow you to place different security precautions...

...NT1310 07/08/2013 Assignment 4 Contrast of Copper and Fiber Optics: Copper has been used in electric wiring since the invention of the electromagnet and the telegraph in the 1820s. The invention of the telephone in 1876 created further demand for copper wire as an electrical conductor. Copper wires in a cable may be bare or they may be plated to reduce oxidation with a thin layer of another metal, most often tin but sometimes gold or silver. Plating may lengthen wire life and makes soldering easier. Twisted pair and coaxial cables are made to reject electromagnetic interference, prevent radiation of signals, and to provide transmission lines with defined characteristics. Shielded cables are encased in foil or wire mesh. Fiber optic cable is one of the fastest-growing transmission mediums for both new cabling installations and upgrades, including backbone, horizontal, and even desktop applications. Fiber offers a number of advantages over copper. Fiber optics, though used extensively in the modern world, is a fairly simple, and relatively old, technology. Guiding of light by refraction, the principle that makes fiber optics possible, was first demonstrated by Daniel Colladon and Jacques Babinet in Paris in the early 1840s. John Tyndall included a demonstration of it in his public lectures in London, 12 years later. Unpigmented human hairs have also been shown to act as an optical fiber Below I explain how Fiber Optics is now the best solution...

...telephone communications. Category 2 cables are also not defined by ANSI/TIA-568. They are capable of data transmission up to 4 MHz with a maximum bandwidth of 4 Mbps. These cables contain four pairs of copper wire. In addition to telephone networks, category 2 cables were frequently used on ARCnet, Apple LocalTalk networks, and 4 Mbps token ring networks. It is not recommended for Ethernet networks. Category 3 cables are recognized by ANSI/TIA-568. These cables consist of four twisted pairs of copper with three twists per foot. Cat 3 cable can be used in 10BASE-T networks and transmit data speeds up to 10 Mbps reliably but can suffer from more EMI than Cat 5. Early PoE specifications support Cat 3 cable. Category 3 cables are still used in telephone wiring, but most structured cable installations are now using Cat 5e or Cat 6 cable. Category 4 cables were initially recognized by ANSI/TIA-568-B and were not recognized by ANSI/TIA-568-C. Cat 4 cables consist of four twisted pairs...

The software can be for the end user which is known as the application software or it can be a Systems application software. 2. Unshielded twisted-pair: UTP, is also known as Category 5, and or Category 6. Consisting of 2 twisted pair of copper wire. UTP is the main type of cable used in LAN topography. 3. Shielded Twisted-Pair: Is similar to UTP, the main difference is that it is has an additional layer of shielding, this shield helps in preventing EMI, and other interference. STP is great application when a cable is being applied near power lines, metal pipes and is not in protected by plenum or conduit. 4. Fiber Optic Cable: Is a great long distance cable. There is Single mode, in which laser is transmitted and there is multimode, in which LED is transmitted. Both fiber cables are use to cover great distances up to allow data to traverse the fiber optic cable near the speed of light. 5.

...In a proper IT infrastructure, it consists of seven total domains. Each domain’s overview consists of risks, threats, and the vulnerabilities that will be found in today’s society. Here I will explain three of the IT infrastructure domains affected by the “Internal Use Only” data classification standard. The first domain is the User Domain. The user domains consist of the Acceptable use policy. This is the guidelines that each user must follow within an organization. If any of these rules are violated, the employee can be terminated. The AUP consist of all the asset of the Richman Investment Company. It is the responsibility for the company to have all employees’ sign a legal document that ensure all assets will be kept confidential. The user domain structure is the weakest link of any infrastructure and has several risks associated with it. There is lack of awareness, and it can be controlled by conducting security awareness training. Another risk is user apathy toward policies, and it can be controlled by implementing acceptable use policies and updating staff manuals and handbooks. The second domain is the workstation domain. A workstation consists of desktops, PDAs or smartphones, or laptops. All employees must have the proper rights and access to be efficient at their job. This tasks falls into the job description of the IT professionals to assign rights and grant access where needed. A few of the following risks are things that may occur within a workstation domain...

The American National Standards Institute is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide. For example, standards ensure that people who own cameras can find the film they need for that camera anywhere around the globe. ANSI accredits standards that are developed by representatives of standards developing organizations, government agencies, consumer groups, companies, and others. These standards ensure that the characteristics and performance of products are consistent, that people use the same definitions and terms, and that products are tested the same way. ANSI also accredits organizations that carry out product or personnel certification in accordance with requirements defined in international standards. 2.

...Wired Media Wired transmission lines are physical systems that are used to transmit certain physical quantities. They consist of a collection of a set of conductors made up of good conductors of electricity, like copper and aluminum, and a wire. Some transmission lines used are t-1, t-3, OC lines, DSL, dial-up, and cable lines. A T-1 line is a copper or fiber optic telephone line that can carry more data than traditional dial-up lines. These lines were originally made with twisted copper. T-1 lines are still being made, but the standard is slowly being upgraded to fiber optic lines. T-1 lines can transmit 1.544 Mbps. They connect geographically separate offices through a private voice and/or data connection. It is very useful for small businesses and commercial buildings with more than 8 lines. Getting a T-1 line is costly (around $1,500 a month), however it could save money for companies who have many phone lines. T-3 lines are a collection of about 28 T-1 lines that can transmit data at 44.736 Mbps. Obviously they are faster than T-1 lines, because they have a collection of 28 T-1 lines. They are used for longer distances than T-1 as well. Similar to T-1 lines, they are used to connect geographically separate offices through a private voice and/or data connection. They cost upwards of $3,000 a month to operate so not all small businesses can afford to have a T-3 line. Optical Carrier lines (OC lines), are a part of the Synchronous Optical Network (SONET). OC-1 is...
