Why mobile phones are implementing hybrid SIM (the second slot can be either be used for second SIM or memory card) while simple dual SIM is better?
I think it may be due to cost factor albeit should save only a fraction for the manufacturer. It also saves the manufacturer from providing another slot in the phone’s body and in the phone’s mother board - which may be a good idea for phones that are water resistant contributing more for saving cost. That said, it could be that the manufacturers “assume” customers may see it as a “cool” feature with hybrid sim slot. But, just like most of the customers, I hate this idea of hybrid slot. It really limits the end user of his flexibility in using the mobile. If manufacturers really need to impress customers why not Dual Sim with Hybrid slot PLUS a micro SD card slot? I’d call that as flexibility and “cool”. I prefer saving all the media in my sd card slot rather than the phone’s internal memory for one simple reason - security. I usually upgrade my phone every two years(if I’m that patient), and when I exchange I just remove the sd card and put it on my new mobile. Saves me a lot of time and retains the folder structure. Moreover, I can rest assured that no one can extract any data from my old mobile that I trade(even after format - using file recovery softwares). On the other hand, having a dual sim enables my to use data from one slot and voice from the second. “JIO”- what else. I’d just use Jio purely for data and use Airtel for calls. I had to reconsider lot of good phones just for this one reason - hybrid sim slot. Hope the manufacturers listen.
Is it possible to use the internet through a USB port from a router?
Yes, under three conditions:The router’s OS kernel supports USB network devicesThe specific USB network device you wish to use is supported by the OSThe router supports using those devices as a WAN connection.There are several devices that do this, most notably the entire Cradlepoint product line, as well as several devices from other manufacturers. You can get a USB511 LTE modem for next to nothing on eBay and the like, get a SIM card from your carrier, and use that as a backup link.
Will the Oculus Quest have expandable storage (such as micro SD)?
As far as I know, it doesn’t (someone correct me if I’m wrong) and that presents a problem. 64Gb is not a lot when it comes to gaming - or VR experiences - so we are going to have to be creative in what we load on to it.The way I see Oculus Quest is that it is a breakthrough in terms of concept as a standalone, 6DOF, HMD with hand-controllers but there will be compromises in terms of battery life (they aren’t saying yet), recharge time, and storage. As with all first-gen tech, we’ll have to live with that.But from everything I’ve seen, it’s still a lot better than what we have.
What do you think of XD memory cards. Most of my other equipment uses SD .?
This camera I like uses XD but some people who offered me advice said they were unreliable and easily corrupted. Any personal experience or comments highly appreciated.
Handgun concealment in single DIN stereo box under stereo ideas/questions on set up/ new gun??? Chl holder?
I have an xterra and I'm wanting a new stereo, something with Bluetooth/disc changer/sd slot/and USB port. Well my oem stereo is double DIN but I'm thinking of getting a single DIN stero with a single DIN box underneath it to store my gun. Right now my carry is a kelteck p40 subcompact but like any gun owner I'm always in the lookout for something else. Does anyone have any advice on a specific stereo/single DIN box/handgun that could fit in a single SIN box. All my handguns are 40s but I'm wanting a 45 or 9 mil something good for conceal carry and I often go in areas that are notorious for hogs so that's something to consider.
I know how to program with Python. Do I need to learn basic electronics and circuits before I buy a Raspberry Pi?
I purchased several Raspberry PI computers, simply to use them as micro-servers.Consider that I can download a complete Ubuntu image, compiled for the ARM architecture of the PI, install it and boot it up. I don’t have to know anything about circuitry to do that.After I installed Ruby-on-Rails, I built a lawn watering system that controlled the 5 sprinkler valves on my home system. Only then did I have to do some research and build a little ‘pull-up’ circuit to convert each of the 3-volt signals from the PI to 5-volt signals necessary to control the relays controlling the valves.It is certainly true that I could use more hardware expertise if I wished to build something more complex, but the Raspberry PI is capable of acting like a small headless web-server without much knowledge of hardware.
What is the difference between USB and SD card?
Q: What is the difference between USB and SD card?Between the two cards? The interconnect and the physical design, that’s about it.Both USB and Secure Digital are digital interconnect standards. USB is a standard for a low-voltage differential serial bus originally designed to replace a variety of PC interfaces for things like keyboard, mice, etc. But over time it became even more “universal”, and now supports storage, including flash memory cards. The standard covers software, chips, cabling, connectors, and power conventions.Secure Digital is a bus that can run at 1-bit, 4-bits, or 8-bit wide, depending on implementation and generation, designed originally, along with a physical card format, as a memory card standard for portable devices. But over time it became more capable, with support for I/O devices added.So a USB thumb drive is logically a memory controller chip with USB bus interface, built to the USB standards so that all modern computers understand it without extra software. This chip is attached to one or more banks of NAND flash memory. It’s true that some thumb drives may put the flash memory and the controller in the same physical package, to save money. A USB thumb drive is designed to plug into a USB jack on a PC, tablet, printer, etc… outside of the device, in lieu of a USB cable.An SD memory card is extremely similar, only with of course a controller chip that understands the SD interface rather than the USB interface. A USB card is designed to go mostly or all the way inside a device: a camera, a phone or tablet, a printer, a PC, etc.The difference between a full SD card and a micro SD card is package size, that’s about it. As for Class 10 vs Class 4, that’s the minimum guaranteed write speed. When you’re recording video, it’s important to ensure your card is fast enough to keep up. A Class 10 card will always support 10MB/s (80Mb/s) writes, a Class 4 card will always support 4MB/s (32Mb/s) writes.
What is USB 2.0 and USB 3.0 ?
USB 3.0 AND USB 2.0 MEANING:USB 3.O :USB 3.0 is the latest revision of the Universal Serial Bus standard released in 2008. This new standard offers increased transfer rates up to 4.8 Gbps, increased maximum bus power, improved power management, and new connectors and cables that facilitate the higher transfer speeds and additional power. Implementation of the technology began in 2009 initially with USB 3.0 adapters (PCIe and Express Card) to allow installation of the new 3.0 ports into current computer systems. Hubs followed allowing additional 3.0 expansion. PC computers and laptops have slowly been implementing the new standard since 2010, but the new 3.0 ports are expected to be in the majority of all new computers by 2012 when the popular manufacturers make it a standard.USB 3.0 cables and devices are also required to achieve the fast USB 3.0 transfer speeds. Currently the majority of 3.0 devices include external hard drives, hard drive docks and flash drives. Additional devices like memory card readers, display adapters, and transfer cables launched in 2011, with more products expected in 2012 and later.USB 2.0:USB 2.0 is a Universal serial bus (USB) standard, released in April 2000. Almost all devices with USB capabilities, and nearly all USB cables, support at least USB 2.0.USB 2.0 is often referred to as Hi-Speed USB.Devices that adhere to the USB 2.0 standard have the ability to transmit data at a maximum speed of 480 Mbps. This is faster than the older USB 1.1 standard and much slower than the newer USB 3.0 standard.MORE DETAILS AND SOURCE IS HERE USB 2.0 VS USB 3.0
