What is Thunderbolt 4?

Image
Thunderbolt™ technology is a cable   connection interface developed by Intel over the past decade. F eatures:       Thunderbolt™ ports pr o vide high bandwidth to connect high   speed devices.   Thunderbolt™ cables help ensure a high   quality connection between your device and your computer.   Thunderbolt™ accessories easily extend your computer's capabilities with docking options and peripherals.   Advantages of Thunderbolt 4   While all ports serve the basic purpose of connecting input or output devices to computers, Thunderbolt 4 ports have multiple significant advantages.   Flexibility There are ports that power your device, ports that transfer data from your device to your computer, and ports that transfer video signals from your computer to an external monitor. Thunderbolt ™ ports do all three things. It provides high speed data transmission,outputs video signals, and can simultaneously power compatible devices (inc...

What is a USB hub and what it can do

Image
A  USB   hub  is a n adapter with several extra USB ports.  Due to  the limited number of USB port   on computer , it' s inconvenient for PC users to achieve  different kinds of work simultaneously .  With a USB hub ,   it' s easy to expand the connectivity for a single USB port .                                                     (Picture Source:  Best Type-C 15 in 1 USB Hub ) Tpes of USB hubs There are two main types of USB hubs, powered and non-powered. Powered USB hubs usually create their own power from an electric powered socket. Powered hubs are excellent if you are connecting USB devices that operate upon higher voltages, such as printers, scanners, and large external hard drives. That means the number of devices you connect with will not count up...

Why are USB hubs mostly 4, 7, and 10 ports?

Image
USB hubs   are  undoubtedly one of the most popular  peripherals out there, but while we're enjoying their convenience, have we ever wondered why USB hubs are 4 , 7 ,   and 10  port s the most common? USB hub uses a star topology to extend multiple USB ports. The core of a USB hub is a master control chip (also known as a bridge chip), which allocates resources from a USB port (upstream port) on a PC to the USB port (downstream port) extended by the USB hub through software and hardware algorithms. You  may have noticed that USB hubs on the market almost always have 4 , 7 , or 10  USB ports. In theory, a  single USB hub bridging chip can be extended t o   4  USB ports .W hy isn't there a hub with 8 or 12 USB ports? The reason goes back to the USB hub topology. Since a hub bridge chip can only expand 4  USB ports, to expand more USB, you have to use more bridge chips at the same time.   Take the 7-port s  USB...

I ntroduction of USB     USB ( Universal Serial Bus )  is a Serial Bus standard, but also a technical specification of the input and output interface. It is widely used in information and communication products such as personal computers and mobile devices, as well as photography equipment, digital TV (set-top box), game consoles and other related fields.   D evelopment H istory of  USB USB 1.0    USB 1.0 was introduced in 1996 with a speed of just 1.5Mb/s(bits per second);  In 1998, it was upgraded to USB 1.1, and the speed was greatly increased to 12Mb/s.   USB 2.0   USB2.0 evolved from USB1.1 and has a transmission rate of 480Mbps, or 60MB/s, which is enough to meet the speed requirements of most peripherals.     USB 3.0    The USB 3.0   Promoter Group, composed of Intel, Microsoft, HP, Texas Instruments, NEC, ST-NXP and other industry   giants , announced that the new generation of  USB 3.0 st...
