Linux Mint Final Review






OS: LINUX MINT

PROGRAMMER/ ORGANIZATION: Clement Lafebvre, Jamie Boo Birse, Kendall Weaver,and Community.

PURPOSE:"The purpose of Linux Mint is to produce a modern, elegant and comfortable operating system which is both powerful and easy to use."




Today, we will be testing two different OS (Operating System),  Windows 7 and Linux Mint.
Where we will be comparing Linux mint to Windows 7 in performance, ease of use, visual, and compatibility with different programs.





Scale: 1-10, 1 being really bad and 10 being good as windows 7.



CRITERIA



PERFORMANCE: 8
 The reason for this score is more the simple use of resources that the operating system utilities. Many users never reported the over use of computer resources, like the CPU rarely was at 100% load when using multiple generic applications such as browsers, music players and movies. The operating system only used about 328 MB on average on any given time when idling. The startup time wasn't anything fancy, specially since we boot up from a CD but if we had actually installed Linux Mint on a hard drive, then the boot up time would have been dropped down to about 30-45 seconds.


EASE OF USE: 6
Being able to boot right into the operating system and log onto the desktop is a great touch. We were able to find very common thing such as calculator, libraries, control panel, personal preferences, and system files. But the system is made for much more experienced users, there were things that didn't have much explanation for a newbie such as the console commands and certain things that can be only done through the console center.


VISUAL:9
we gave it 9 on visual because was a bright and clear interface. there weren't many pre-loaded apps and it because of that it was easy to find what your looking for. In this category I actually like better than windows seven because there were less preloaded apps. it is  much more minimalistic and has a cleaner look and feel to it.


COMPATIBILITY: 9
We tried to use a numerous amount of programs that a typical windows user would be using for everyday tasks such as Word, Internet explorer, Firefox, and Google Chrome and we couldn't forget the gaming side of PC, tried CS;S. To our surprise, they all worked amazingly great and speedy except for internet explorer which felt buggy and funny. Even thought you can't always native install a windows program and run it, we found many useful and easy to use programs that allowed us to install Windows applications and run them with ease.


OVERALL: 8
For trying out a new Operating system, Linux Mint wasn't that hard to get used to, it wasn't too complicated but it wasn't too easy; just right. Yes, we did have some complications figuring out some Administrator tools but besides that, everything was very easy to understand and follow through just like you would on a Windows computer. Linux is meant for users who want to be more in control of what their system does. The developers did a great job letting the end user have full control as to how their system will look, feel and function. With a couple lines of code, you can modify your system to your very own personality and work potential. The easy installation of programs that your average joe would use on a Windows 7 computer, means that a person can fire up Linux Mint and with a couple of tutorials and understanding, be able to be in full control of their computer, something  a Windows computer takes more effort to do.

we feel that linux mint could appeal to a wider audience if they work harder to further increase the capabilities of software that the general public utilizes in their everyday work.





Installation / Start Up Time

The boot up time for Linux mint was about 45 seconds, sometimes longer.


You will be prompt to choose a language for the installation process.


It will then ask you if you have the required space needed for the installation and if you are installed to the internet.


It will then ask you if you want to fully format the disk and or save the current files saved on the hard drive before the actual installation.


You will then select the location for the installation, the default located seems to work best but you are able to install in other places.


Next, it will ask for time zone you would like to use.


Now, you choose the language and layout preference for your keyboard options.


Now you are able to add a layer of security to your system by creating a username and a password for that specific account/ computer.

You should be all done now, ENJOY! ;D

The Evolution of the Cellular Device





Contacting a friend, teach or parent is just a matter of a couple buttons presses now a days but if you go back a decade, things were a lot more different than today.
History: 

"In essence, a cell phone is a radio. One of the most interesting things about a cell phone is that it is actually a radio -- an extremely sophisticated radio, but a radio nonetheless."

The telephone was brought to life by Alexander Graham Bell 1876, changing the way people could communicate. The idea of telephones being wireless comes from the creation of the radio by Nikolai Tesla in the 1880's.

The early wireless telephones were really big, and to give you an ideal of how big we are talking about, you would have needed to fit the components needed to get the phone working in the passenger seat of a vehicle, or in this case, in the back of a car.

.



Purpose: Communications with people near and far, across both land and sea.



Technology:

Signal from cellular devices get sent to radio towers that transmit the signal between your cellular device and the satellite that then transmits the signal to the end user.

For you to be able to talk to the person at the end of the other line, the signal first needs to be transmitted to and back from that person. For this to occur, the signal must first travel through what is called a Channel. A Channel is like a gateway or a one-way tunnel for the signal to travel through. As  like any other tunnel, only a certain number of cars; in this case, signals, can go through the channel at any given time. As more and more people were able to afford a cellphone, this caused one issue, not my users could be on the same channel that the signal was being transmitted on.

This lead to the creation of Cells, which are allowed about 800 frequencies per channel. This meant that about 56 persons could talk simultaneously on the same channel.

When one Channel gets full, the cellphone will transfer the signal to another frequency. Now when you drive down the road and talk on the phone, you're call never gets interrupted because of one magical thing called Cells. Throughout the United States and the world, there are Radio Towers spread out to have a coverage area. When you move away from one Radio Tower, your signal gets moved from Cell to Cell. Allowing continuous talk.

Better upgrades later, a cellular device could transmit its signal across more than 1,664 channels or more!
