Unit 1 Assignment 1

Cell phones – Cell phones use data networks to communicate over radio frequencies. The frequencies that they use are also shared with television, Bluetooth, and Wi-Fi.
Landline phones – Landline phones use voice networks only because they do not need as much speed as anything else. Normal house phones use approximately 10 MB/s which is all that voice networks handle.
SMS/Text messaging – Text messaging uses data networks because they can also be sending media like pictures and video. The other reason that I believe that text messaging uses data networking is because it is faster.
Fax machines – Fax machines use voice because they only transmit exactly what is on the paper. It is not being transformed into little packets and sent over the internet to another place; it is just sent from one place to another through the phone line.
Pagers – Pagers use the same as cell phones and that is data networks because it is wireless, and does not have to be plugged into anything. Pagers are not that common due to the cell phone industry growing swiftly.
VOIP – VOIP as it says in the name of it uses a data network. It uses IP for talking so that the communication is more secure and not many people can tap in as easily as people can over regular phones.
Skype/Facetime – Skype and facetime both use data networks to communicate because you are sharing video with somebody else. You are also receiving video, and video cannot be shared over a voice…...

...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 7. Assignment 1. Refraction, Reflection and Optics Refraction: The most common real life example used when discussing refraction is a straw in water. When a straw is placed in a glass of water and viewed from the side, it appears to be broken or bent. This is due to the difference in the refractive indices of air and water. Since water is denser than air, the straw appears to bend as the light it reflects is slowed by the density of the water. This phenomenon also makes submerged objects, such as fish look closer to the surface than they actually are. Another common example is a rainbow, where sunlight is refracted by raindrops. Sunlight consists of a mixture of different wavelengths, or colors, of light, with blue, for example, having a shorter wavelength than red. When this light passes through raindrops, the shorter wavelengths are bent more than the longer ones, splitting the light into its different colors. Reflection: Pretty much everything you see could be considered reflection. The fact we can see is due to light reflecting off of objects and into our eyes. A good example, I guess, is the moon. When it glows at night that is just light from the sun reflecting onto the Moon's surface, and bouncing back, giving it that glow. Degradation of signal strength in fiber-optic transmission. The main factors that affect this is number of connectors, splicing, Quality of Fiber / connectors, also not using an Attenuator according to the distance, or using dirty......

...Unit 1 Exercise 1 Local Exchange When you send an email from New York to Japan, that email,is sent from your home to the local exchange point over the access network. Once it is in the local exchange it is then sent to aggregating points in different cities and counties over the regional network. Then it is aggregated and transported over the long-haul network so that it reaches the launching point at the country shoreline where it is then sent over the ocean network to Japan. Once there, the email is sent back over the long-haul or regional network to the local exchange and then on to the individual receiving the email. This occurs using mostly fiber optics so the speeds at which all this takes is at the speed of light which is approximately 127,000 miler per second. understand how to interface with the local exchange you must first understand the different networks that comprise it. The first network, being the access network. The access network is the network that connects the individual user or business with the telecommunications system. This is made up of a series of fiber-optic and copper cabling and passive and active equipment that connects you to the local exchange. The central office at the local exchange contains the switching equipment to direct your telephone, data , video, etc. to where it needs to go. The access network is very important to the local exchange since it’s the part that reaches the end user, who is you, and connects them. The metro network,......

It’s a two-way that carries full duplex conversations. Cell phones have evolve from 1G, which carries information similar to the way fixed line phones transmit voice from subscriber to central office to 4G network for fast access of the internet. It uses both voice and data networks. (woodward, 2012) Landline phones – Initially landline phones started as a device to transmit voice. While it didn’t seem like a good choice to transmit data, however, for many years it was subscribers’ only choice for transmitting data. SMS/Text messaging –The short messaging services (SMS) still works on voice networks. It is the mechanism of sending short messages over mobile networks. The message from the sending mobile is stored in a central SMS center which then forwards it to the destination. SMS can be no longer than 160 characters. (http://www.wirelessdevnet.com) Fax Machine – short for facsimile machine is a device that can send or receive pictures or text over a telephone line. It works by digitizing the image into grids of dots. The dot is either black or white representing on or off.
