What is 192.168.0.1?

192.168.0.1 is a common Internet Protocol (IP) address for many wireless home routers, used to access administrative functions.

Just as someone needs your mailing address if they want to send you a letter, your computer needs what's called an Internet Protocol (IP) address to send and receive messages across the internet. This IP address is a unique string of numbers, in a specific pattern, separated by periods. One common one is 192.168.0.1, baffling many everyday internet users.

Back in 1996, two groups, the Internet Engineering Task Force and the Internet Assigned Numbers Authority, had to pick a handful of addresses for use in closed networks, not public ones. One was 192.168.0.1. The form is called "dot-decimal," meaning 192.168.0.1 is a decimal conversion of 11000000.10101000 in binary code, with all those 1s and 0s corresponding to the size of the address (i.e., how many individual addresses it can support). The first digits, 192.168, identify the computer network address while the last two digits signify the actual computer ("host") address. For in-the-weeds reasons, the last two digits vary (eg., 0.0 or 1.0), so sometimes 192.168.0.1 is referred to as 192.168.x.y.

So … what does all this mean? This part is pretty simple. Typing in 192.168.0.1 is an easy way to access the administrative functions of your router, the device that connects your computer to the internet. This is useful if you need to troubleshoot a network problem, or, say, change the password of your router.

the Battle of 192.168.0.1 was just horrific. lost so many friends there.

If you're using a Netgear router, simply enter http://www.routerlogin.net in the address bar of your browser or navigate to 192.168.0.1. The username is almost always "admin," and the password will either be "password" or "1234" if you're using an older device.

If you're having issues with your wireless connection or password, knowing the numbers 192.168.0.1 will come in handy—only if your router uses that address. If technology really isn't your thing, your computer-savvy friend will probably recommend that you type in 192.168.0.1 or some variation of it.

IT folks sometimes use 192.168.0.1 in memes to poke fun of the computer-illiterate or make other inside jokes that are sometimes over our language-loving heads here at Dictionary.com.

Note

This is not meant to be a formal definition of 192.168.0.1 like most terms we define on Dictionary.com, but is rather an informal word summary that hopefully touches upon the key aspects of the meaning and usage of 192.168.0.1 that will help our users expand their word mastery.

Where to Use USB-A Jack

The term USB stands for Universal Serial Bus, as the name implies it is universal form of communication which is even now supported by all hardware and software that has USB host. This works through Asynchronous Serial Protocol, meaning there is no clock shared between the sender and receiver. Every device that we connect to USB port works though this protocol. If a Microcontroller or Microprocessor supports USB host then we can connect any USB device like Keyboard, mouse, camera, printer, MP3 player etc to exchange information between this device and the host (uP or uC). It can also be used to transfer data between two Microcontrollers and Microprocessor, if you project requires you to do so. Few popular microcontrollers that support USB host are Arduino USB host, UMFT120DC, Arm Cortex M4 etc..

So if your project requires you to establish an USB connection, then this jack can be connected to the device and wired to your uP or uC.

How to use USB-A Jack

The USB Jack has only three pins and hence is relatively simple to use. Out of the four pin two pins (pin 1 and Pin 4) are used to provide the Vcc and Ground. The supply voltage of Vcc is +5V and is usually provided from the Microcontroller itself. The ground pin is connected to the ground of microcontroller.

The remaining two pins are the D+ and the D-. These pins should be connected to the D+ and D- pins of the host respectively. They also require a pull-down resistor of value 15K each for the data to transfer. A sample connection set-up is shown below.

USB-A Jack Circuit Connections

Based on the microcontroller you are using there are a tons of library that are available to work with USB protocol, use one of them and you should be all set to use USB peripherals with your project.

Applications

  • Interface Keyboard or mouse with MCU
  • Serial Bus connections
  • Portable and pluggable devices
  • Small distance, high speed communication

Difference Between USB 1.0 And USB 2.0

usbUSB 1.0 vs 2.0

The Universal Serial Bus or USB has become the most used port in computers today. It currently exists in two versions. 1.0 which was the original standard of USB, and 2.0 which is the improved version for newer devices. To the end user, the difference between these two devices is purely in its speed. USB 1.0 devices can only achieve a maximum speed of 12Mbps while 2.0 devices can theoretically achieve up to 40 times that at 480Mbps. The real world speeds are lower for both standards since there are other factors that can affect its total throughput.

Originally intended for much slower devices, the initial USB implementation did not provide any option for high speed data transmission. Devices like mice, keyboards, game controllers, and a few others, which were the devices that USB was for, usually transmitted only a very small amount of data to function properly. But as USB became more popular, more devices also began to switch to USB because of the growing popularity of the USB port and the relative ease of plugging in devices. High speed devices like thumb drives proliferated quickly, and digital cameras and camcorders began to sport a USB cable for connecting to computers, but the hindrance of very slow connection speeds became quite apparent rather quickly.

The 12Mbps speed of 1.0 devices is already an upgrade to the very first standard which only allowed 1.5Mbps connections. USB 1.0 devices can either be a low speed device which runs at 1.5mbps or a full speed device at 12Mbps. A connecting device must identify whether it's a low or full speed device at its initialization. USB 2.0 adds the high speed connection to the previous two, and it is in high speed that you can get the 480Mbps theoretical throughput.

Because USB 1.0 can only recognize low speed and full speed devices, USB 2.0 must create a workaround in order to retain backwards compatibility with the older standard. A 2.0 device identifies itself as a full speed device at first then negotiates with the controller via a series of chirps. Once the controller identifies the device as a high speed device, the connection is then reset to and high speed signalling is used.

Summary:
1.USB 2.0 is the upgrade of 1.0
2.USB 2.0 is much faster compared to 1.0
3.USB 1.0 has two modes of operation while 2.0 adds another one
4.USB 2.0 devices needs to connect as a 1.0 device and negotiate for a 2.0 connection
