Big Data, Privacy & Cybercrime

Image
During the previous lessons i have learned a lot about data and protection and cyber crime and how to prevent it from happening. To protect one from cyber crime you must make sure to have different passwords for different accounts and not to click on any links or emails that are not from the people you know. If you do become hacked or your information is leaked you can become a victim of identity theft and your money and information will be stolen. Currently I do not check for fishing and accidentally click bad links while also using the same password often so i will try to stop doing those things.

History of Computers

Image
Early computers have been around for years and have been helping humans with mathematical calculations since the early 1500,s. The first electronic computers were built in order to stay on top during times of war and the first computer was made to decipher codes form the nazi party and later stronger computers were made in order to calculate missile strikes and other various attacks. Computers were made in order to help with large calculations humans could not due quickly. One new fact i learned is that computers were started in the 1500,s. The 2nd new fact i have learned is that the eniac was 40 feet wide. The 3rd fact is that the computer was used to calculate missile strikes. 

Computer Data Storage and Binary

Image
A computer turns analog inputs into data and converts it into a code of zeros and ones so the computer can read the data.  A bit is a small electrical device that can be either 1 or zero and it is a micro transistors that holds a electrical charge. 8 bits are 1 byte. For every bit they are either a 1 or on or a zero which is off which means a number in the number system and it is 2 squared for every 1. Learning the way to turn bits from 1 and 0 to numbers is very difficult

Analog vs. Digital Data and the Python int command

Image
The int command allows numbers to be round down to the next denominator. Analog uses waves of electricity to be able to work and record or hold data and digital uses binary information to record or use data that can effect the code. a modem allows regulation for the internet and makes sure that the internet is up and running and able to transfer data from the internet in zeros and ones. Learning all the new info was quite hard since their is a lot to remember.

Python input command and variables

Image
The new python command I learned to use was the input command. The input command allows us to be able to store information to be used later and can be assigned a name that will be used later in the command. It can also be used as ways to get variables to certain questions and can be used to record the data of the answers. the difficulties I faced were the naming of the programs since they cant be separated and can't have certain symbols. I think that learning how to use the input command was fun and was very entertaining.

Getting started with python

Image
The new python command learned is print. The command is one that allows any user to be able to print any text by using print("enter anything"). it is very useful for having words display or making things out of text. I have used this before in a different unit so their was no difficulties in using the print command. I was able to make a little doodle with the print command which is something I have not done before. The python command is very similar to other things which makes it very accessible.      

python programming

My name is christian mendoza and i will be writing reflections on what i learned during my python programming class. I mostly just use my phone or playstation not really using my laptop. I use things like Twitter and other social medias.I learned how to code from hour of code but i don't have much experience. I hope to learn to be able to fully code using python.
