Background:

The conflict takes place in Ukraine, Black sea and Russian Federation. It started on 26 February 2014 and is still ongoing. The leaders are Vladimir Putin for Russia, Petro Poroshenko for Ukraine.

What happened?

Many Ukrainians got angry with their formal president, Viktor Yanukovych. This action led to Ukrainian revolution (February 2014). Then series of changes happened in Ukraine’s political system. After the revolution, Russia refused to recognize and accept the new government that was created during the revolution.

Pro-Russian argument:

Russia’s main argument states that their only need is legitimately protect that region due to majority of Russian speaking people. Russia also says that the real reason is to protect the citizens of Russia in the Ukrainian area, especially the Crimea area and cities like Luhansk, Mariupol, Donetsk.

Pro-Ukrainian argument:

Very few people do not blame Russia for what is happening in Crimea and in Eastern Ukraine. Over 70% support keeping Ukraine united. Very few people in Ukraine see the issue of Russian language in Ukraine as needing urgent changes and also Ukrainians do not trust Russian officials.

Crimea must be reunited with Russia:

Historically, Crimea is Russian. Ethnically Crimea is nearly 60% Russian, 20% Ukrainian, who are mainly pro-Russian. Politically, Crimean people are stuck with Ukraine and most of them would like see Crimea as a part of Russia. If there was a democratic voting about the Crimea, the majority of people would definitely vote for joining with Russia.

Donetsk and Luhansk:

Even though those states are self-proclaimed, they should definitely not be called terrorist organizations. Luhansk and Donetsk are now recognized as self-proclaimed states and majority of citizens wants to see those two states joined with Russia, therefore there is no reason this should not happen. They have right to exist, unfortunately Ukraine consider them as terrorist and separatists due to their need to separate and cooperate with Russia.
Joining with Russia would benefit Russia and Ukraine equally, because the politics and economics are very problematic.

Sanctions:

United States and European Union put sanctions on Russian individuals and businesses. During the crisis the scope of the sanctions increased. Russian government responded in calmly did not fight against them, only put few sanctions back on USA and some european countries. These sanctions are not fair at all because they only create problem and do not solve the conflict.

USB is the most universal connection to connect devices into computer such as digital cameras, printers, scanners and external HDD. USB is supported by the most popular operating systems, so it is called cross platform technology. Development started in 1994 by a group of seven companies;  Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel.

First USB that was widely used was called USB 1.1. It was released in September 1998. Speed was 12 Mbit/s and was intended for higher-speed devices like disk drives. 1.5 Mbit/s rate was much lower and was used for devices such as joysticks or gamepads. iMac played major role at popularizing the USB.

USB 2.0 was released in year 2000 and immediately became official standard. USB 2.0 had backwards compatibility with its predecessor USB 1.1. This means that if you have newer USB 2.0 port, USB 1.1 devices can still be plugged in and will work perfectly. USB 2.0 support plug and play capabilities for most of the multimedia and storage devices. Speed is 480 Mbit/s which is 40-times more than in the previous USB 1.1.

In year 2000 was also released USB flash drive, a rewritable plug and play storage device that was first sold by IBM and Trek Technology companies.

USB 3.0 is the latest version. Its super speed data transfer rate is up to 4.8 gigabits per second. It also offers backward compatibility with USB 2.0 and ports. If you plug USB 3.0 into USB 2.0 port, the super speed will not work because it requires and USB 3.0 in order to reach the super speed. First devices to support USB 3.0 were released in 2010.

Next generation of USB called USB 3.1 was released in year 2013. The main improvement was boost of data transfer of up to 10 gigabits per second. Also new improvements and features were added like improved data encoding and efficiency, doubling the speed of generation 1 standard. To make it clear. 50 gigabyte Blu-Ray disc could be transferred with USB 3.1 in just 38 seconds.

Development of similar USB 3.1 has started in year 2014 and is called USB Type-C. It is a new small reversible-plug connector for USB devices. Type-C is supposed to be future-proof, comparing to Apple’s Lighting and Thunderbolt, it has the same idea. Type-C devices also has its power currents of 1.5 A and 3.0 A over the 5 V power bus in addition to baseline 900 mA. Type-C cables are meant to be active, electronically marked cables which contain a chip with an ID function based on the configuration data channel. This new type of USB is meant to be very popular in the close future.
