Android is a mobile operating system developed by Google. This system is used by several smartphones, such as Motorola Droid, Samsung Galaxy, and Google itself through a device called Nexus. The Android operating system (OS) is based on the open Linux kernel. Unlike the iPhone OS, Android is open source, which means developers can modify and customize the OS for each phone. Therefore, different Android-based phones may have different UI graphical user interfaces even though they use the same OS.

Android phones usually come with some built-in apps and also support third-party programs. Developers can create programs for Android using the free Android SDK (Software Developer Kit). The Android program is written in Java and runs through Google's "Davlik" virtual machine, which is optimized for mobile devices. Users can download Android "apps" from Android Market Online.

Since some manufacturers make Android-based phones, it's not always easy to know if the phone is running an Android operating system. If you are not sure what the system is using the phone operation, you can often find the information system by selecting "About" in the Settings menu. The name "Android" comes from the term android, which refers to a robot designed to look and act like a human.

The most popular smartphone manufacturer is Samsung, Samsung is the most successful Smartphone manufacturer today, devices like the Samsung Galaxy "S" series and the "Note" series are touted as the most advanced smartphones on earth today.

Android is developed privately by Google until the latest changes and updates are ready for release, and information about the source code also begins to be disclosed to the public. This source code will only run without modification to certain devices, usually on the Nexus series. There is a separate binary provided by the manufacturer for Android to operate.

As the development of Android, there are now many available Apps that can be obtained easily. Millions of apps are now scattered and can be used for everyday user activity. We can easily download the apps in the Google Play Store. However, if Android users do not have the Google Play Store App then one alternative is to use APKs. One of them is by using androidapksbox.com updated daily. But the download speed of the storage server is classified as less quickly. So it can be improved. The addition of bandwidth also needs to be done.

• Bandwidth is the magnitude of the transmission line through which information or data passes.
• Thus, bandwidth determines how much data can be transmitted per unit of time (usually time units of seconds).
• Bandwidth can be analyzed as the magnitude of a highway, while the data are the cars that run on it. Usually bandwidth is unified Mbps (Megabit per second).

In other words, the wider the size of the road, the more smooth the car traffic as more cars can pass over it. So also with bandwidth, the greater the bandwidth, the greater the volume of data that can pass in the communication channel.

Often the problem is when your internet suddenly slows. Actually, what happened? Suppose your bandwidth is 7.2 Mbps, but suddenly it sounds like 1 Mbps. This does not mean the bandwidth or channel you are using turns narrow.

Actually, the channel you use remains the same, the magnitude, the capacity, remains the same. But the portion of the channel you can use is smaller. This is because there are other users who use the same channel, so you have to share the channel. The term is a contention ratio, a term that describes the number of subscribers sharing a pipeline or bandwidth.
