Visual Basic

Posted on

Wanna know how to make a program that can do anything you can imagine?  Try Visual Basic!  Visual Basic is one of the great beginner programming languages a person new to coding could start off with.  To start coding in Visual Basic all you need is some experience in basic math, common sense, a good memory and a lot of imagination. 

            Visual Basic was originally invented by Microsoft to make windows form and console applications for use by developers to run simple tasks like self-extractors or file deletion console applications.  Now it can do things like make games and advanced programs like Office Word or Powerpoint. 

            Visual Basic’s code is based off of the Binary number system of 1’s and 0’s called machine code (The most basic of all coding).  It then takes it and converts all the 1’s and 0’s into understandable variables and lines of words and punctuation.  An example of the Binary that Visual Basic or any languages are based off of is:    

1          =          0000

2          =          0001

3          =          0010

4          =          0011

5          =          0100

6          =          0101

7          =          0110

8          =          0111

9          =          1000

And on and on and on until you get a pattern that makes up words!

Ulrich Zwingli

Posted on

          Uldrich Zwingli was an early Swiss reformer in the 16th century AD.  His main goal was to remove all the pressure provided by the Catholic Church from the common people.  The main reason these early reformers like Zwingli or Martin Luther came about was all the restrictions the Catholic Church provided that restricted people from doing simple things like owning their own copy of the Bible. 

            This restriction included all the bans on sinning, different laws about having kids and more.  However, what really made many of these reformers mad was the fact that the pope was selling these little pieces of paper that got “rid” of all your sins.   These “Miracle” papers where called indulgences and the profits where used to use build a GIANT cathedral for the pope and his people only.  The reformers hated this because it gave people a false sense of relief from bad stuff they did and all the money went to a bad cause.

            Ulrich was an interesting reformer because he did not put himself out there about his beliefs Except about his belief that everyone should be able to read and own their own copies of the Bible (At that time only the church leaders owned copies of the Bible.  This got him into trouble later when he started getting more famous for his small rebellions.  His followers started getting angry when he was not “putting in his all” during the reformations.  The followers had had enough of his weak dedication to the reformation.  Therefore, all the followers decided to form a group of hardcore rebels called the Anabaptists they took the early reformers ideas even farther and they ended up getting themselves in much more trouble even than some of the famous reformers. 

            Some remaining examples of Anabaptists are the Amish and Mennonite religious groups.  One way the Anabaptists took it to far was they baptized there children before they where eight days old which caused a lot of early deaths that could have been prevented.  Some of the lasting changes to the Catholic Church was that the church was no longer allowed to use Organs for music, also the priests where now aloud to get married freely without shame and being shunned.

            There you have all about the latter part of the early reformation and Ulrich Zwingli and his followers.  That part in time was very important to western civilization because it allowed people to warship the bible in the way and amount they wanted without being shamed or even killed by the church.  One thing that allowed the people to get copies of the Bible was the new invention of the Gutenburg Printing Press.  Without that they might never have gotten the Bible out there.

           

 

Computer Parts

Posted on

            Most computers contain several key components including: A Graphics Processing Unit (GPU), A motherboard (or MoBo), A CPU (Central Processing Unit), Some RAM (Random Access Memory), A Hard Disk Drive (HDD) A chipset (Basic Integrated operating system or BIOS), and A Power Supply Unit (or PSU).  All these parts come together to form a complete computer now of course there are some other parts that can be added like expansion cards, extra ram or hard drives, but for the most part those are the main parts.  Now lets go over each one individualy: 

            The Motherboard is the main part of a computer like the home base.  it brings all the parts of a computer together and connects them electrically.  It holds everything except the power supply and hard drive(s).  The motherboard also constains the chipset which is a tiny storage device chich conatins a BIOS(basic integrated operating system) that allows you to control the computer without a hard drive and also allows you to perform functions like overlcokcing the CPU and Graphics card, Aswell as configuring a new operating system.                                   Image

            Next is the CPU, the CPU is the brain of any computer.  A CPU consists of over a 100 billion transistors operating with a 1 or 0 binary code.  The CPU makes all the calculations that go on inside a computer.Image

            Now there is the RAM (Random Access Memory) RAM is used as temporary solid storage while a program is running to store temporary files concerning the project.  The more Gigabytes of RAM you have the more programs you can run at once.  RAM clears itself when the program is shut down but it is completely wiped when you shut off your computer to clear the OS (Operating System) files off. Image

             Next, there is the ALMIGHTY GRAPHICS CARD!  The graphics card is the piece of hardware that displays pixels and movement on your desktop or in a game. The better the graphics card you have the more graphical capability you have.  Some graphics cards can go from under $50 to over $3000 depending on the amount of graphic cores and amount of GDDR5 Video RAM.

            Now, there is the hard drive, a hard drive is the main source of storgae for a computer as the RAM is wiped every time there is no power.  The most common type of hard drive is the HDD or hard “disk” drive.  The disk drive had a disk that spins at 7200 RPMs standard.  The newer type of hard drive that is becoming more and more popular is the SSD, which uses conductor chips instead of magnetic disks.  This type of hard drive is very hard to break unlike the HDD which can break from a small drop.  SSD’s also has a much faster Data transfer rate when compared to a standard HDD.

Image

              Next is the PSU (Power Supply Unit) this is piece of hardware that powers all the parts of a computer.  It has many different electrical components inside including transistors and a small ICB (Integrated Circuit Board) to hold everything together.  Most PSUs have a fan for cooling the transistors and ICB that is on the top of the box.  The final component of a PSU is the wire harness, which comes out the side and has tons of different connectors for each piece of hardware.

Image

              Finally, we have expansion cards that might add more of a type of port or more slots for RAM chips or graphics cards.  The one below is a expansion card which adds more of the new USB 3.0 via a PCI Express mini slot on the motherboard.

            Now to round up I will show you the back of a computer with labeled ports so you know which ports are which.  I hope you enjoyed learning what different parts of computers do.Image
