आपने शायद देखा है कि आपके इलेक्ट्रॉनिक्स किसी भी एक समय में आप का उपयोग करने के लिए उत्तरोत्तर गर्म हो जाएंगे। कुछ उपकरणों में ओवरहिटिंग से बचाने के लिए शीतलन तंत्र या पंखे होते हैं। लेकिन फ्लैश ड्राइव गर्म क्यों होते हैं?
फ्लैश ड्राइव लगातार और भारी उपयोग के माध्यम से गर्म हो जाते हैं, इसके धातु के घटकों को गर्म करने के कारण, और ड्राइव या होस्ट डिवाइस की विफलता के कारण।
USB ड्राइव के उपयोग के साथ थोड़ा गर्म होना असामान्य नहीं है, चाहे वह कुछ मिनटों या घंटों का हो। वास्तव में, यह वैज्ञानिक रूप से अपेक्षित है। USB ड्राइव का उपयोग अपने और होस्ट डिवाइस (यानी आपके कंप्यूटर) के बीच सूचना को संग्रहीत करने और स्थानांतरित करने के लिए किया जाता है। दोनों के बीच निरंतर स्थानांतरण गर्मी का कारण बनता है क्योंकि यह डेटा को स्थानांतरित करने के लिए ऊर्जा लेता है। दोहराए जाने वाले उपयोग के माध्यम से, अतिरिक्त ऊर्जा का उपयोग किया जाता है और गर्मी में तब्दील हो जाता है।
अधिकांश अन्य घटकों की तुलना में धातु को अवशोषित करना बेहतर होता है जो फ्लैश ड्राइव बनाते हैं। जैसा कि आप कल्पना कर सकते हैं, धातु यूएसबी ड्राइव अक्सर प्लास्टिक या लकड़ी के ड्राइव की तुलना में गर्म हो जाते हैं। धातु शरीर को संभालने के लिए कभी भी गर्म नहीं होना चाहिए।
हालाँकि, कुछ चीज़ें USB को ज़्यादा गरम कर सकती हैं और संभावित रूप से नुकसान पहुँचा सकती हैं। एक ठीक से काम करने वाली ड्राइव को ज़्यादा गरम नहीं करना चाहिए, लेकिन अगर यह जिस बंदरगाह से जुड़ा है वह दोषपूर्ण है, तो इसे बहुत अधिक शक्ति प्राप्त हो सकती है। अतिरिक्त शक्ति, जैसा कि ऊपर उल्लेख किया गया है, गर्मी में स्थानांतरित किया जाता है और संभवतः आपको या ड्राइव को जला सकता है। यह विशेष रूप से धातु कनेक्टर के साथ सच है, इसलिए ध्यान रखें।
इसके अलावा, यदि आपका ड्राइव बहुत गर्म हो रहा है, तो यह भी संभव है कि एक आंतरिक घटक विफल हो गया है और बहुत अधिक बिजली यूएसबी से गुजर रही है।
यदि आपकी ड्राइव आपको जलाने के लिए पर्याप्त गर्म है, तो कपड़े या पोथोल्डर्स के मोटे टुकड़े का उपयोग करके इसे कंप्यूटर से सावधानीपूर्वक हटा दें। इसे ठंडा होने दें और दूसरे ड्राइव के साथ पोर्ट का परीक्षण करें। यदि यह गर्म होता है, तो आपके पास एक दोषपूर्ण यूएसबी पोर्ट होने की संभावना है। यदि नहीं, तो आप सुनिश्चित कर सकते हैं कि गलती बहुत गर्म ड्राइव के साथ है।
यहां टूटी हुई फ्लैश ड्राइव डेटा रिकवरी के बारे में जानें और यहां टूटी या दूषित यूएसबी ड्राइव से डेटा कैसे पुनर्प्राप्त करें।
अपने USB ड्राइव को मध्यम तापमान पर रखना महत्वपूर्ण है क्योंकि इसके आंतरिक घटक तापमान के लिए अतिसंवेदनशील होते हैं। यदि वे अधिक आर्द्रता और तापमान (या तो बहुत गर्म या बहुत ठंडा) के संपर्क में आते हैं, तो मेमोरी और कंट्रोलर चिप्स खराब हो सकते हैं और पूरी तरह से दूषित हो सकते हैं। गर्मी के लिए लंबे समय तक जोखिम विशेष रूप से आपके ड्राइव को बहुत जल्दी मार देगा। अपनी कार या बाहर जैसे चर वातावरण में अपनी ड्राइव को छोड़ने से बचें।

Use a USB-USB Cable to Transfer Files from PC to PC Without Internet
If you don't want to use a third-party program to transfer files offline, another way is taking the USB-USB cable for help. To do so, you need a USB-to-USB bridging cable or USB networking cable as shown below.
This PC data transfer cable works great for transferring files and folders (do not transfer programs) when upgrading from an older Windows 10/8/7 computer to a newer one. Both Windows 32-bit and 64-bit versions are supported. You can buy a USB transfer cable on amazon for $54.45.
Now, let's learn how to transfer files from PC to PC without internet via the USB transfer cable.
Step 1. Boot both the PCs. Wait till both of them finishes the startup process and are ready to be used.
Step 2. Insert one end of the cable into the USB port of your PC 1, and the other end into the USB port of PC 2. Wait till both the PCs recognize the USB cable. This should also start an installation wizard.
Step 3. Choose the installation type by selecting the "USB Super link adapter." Then, click "Next" to continue.
Step 4. Select "High-Speed Data Bridge" from the "Mode" drop-down menu.
Step 5. Click on the"Start"menu and select "Run...". Type devmgmt.msc and hit "Enter".
Step 6. Click on the little plus sign to expand "System Devices." Check to make sure your USB cable is listed as "Hi-Speed USB Bridge Cable." Your cable may use a slightly different name, depending on the manufacturer.
Step 7. Insert the installation disk that was packaged with the USB cable into your CD/DVD-ROM drive. Follow the guided prompts to install the data transfer software. Repeat this step for the other computer to install the same software.
Step 8. Launch the program on both computers. You should see a two-sided window. On its left side, it will show your computer, and on its right side, it will show the remote computer or the new computer where you want to transfer the data.
Step 9. Select the drive/partition as per your preference. Drag the folders and files you want to transfer and drop them to the desired location. Disconnect the cable when the transfer is done.
As you can see, this method has three obvious disadvantages:
This method is very complicated and extremely difficult to operate.
A USB-to-USB bridging cable is expensive. It's more expensive than buying third-party PC data transfer software.
The USB cable doesn't support migrating applications, only files, and folders.
So, to avoid these inconvenience, we highly recommend you try EaseUS Todo PCTrans to transfer files without internet in a much simpler way. It takes only two steps to complete the transfer - creating the file image on source PC and restoring the image on the target PC.
Wrap It Up
This article covers the two most useful solutions to transfer files from PC to PC or move files from laptop to laptop without internet. After reading the content and making a comparison, we believe that it's better for you to do it with an easy and reliable PC transfer program instead of the complicate USB cable. Additionally, if the data is not very large, you can use an external hard drive to copy and paste files from one computer to another offline.

Online transfer is the counterpart of offline transfer, which is also the actual needs of most people. You can transfer files from one PC to another or transfer files from one laptop to another wirelessly in a few ways. The how-article - transfer files from PC to PC in Windows 10 shows you the two easiest ways to migrate data from PC to PC by using a 1-click PC data transfer tool and Windows 10 Nearby sharing feature.
RS-232C, EIA RS-232, or simply RS-232, refers to the same standard
defined by the Electronic Industries Association in 1969 for serial
communication.
DTE and DCE
DTE stands for Data Terminal Equipment. A computer is a DTE. DCE stands for Data Communication Equipment. A modem is a DCE.
DTE normally comes with a Male Connector, while DCE comes with a
Female Connector. However, that is not always true. Use the simple way
below to confirm: Measure Pin 3 and Pin 5 of a DB-9 Connector with a
Volt Meter, if you get a voltage of -3V to -15V, then it is a DTE
device. If the voltage is on Pin 2, then it is a DCE device.
Note: The result for a DB-25 Connector is reversed (Please refer to DB-9 to DB-25 conversion table below).

RS-232 Connections
A straight-through cable is used to connect a DTE (e.g. computer) to a
DCE (e.g. modem), all signals in one side connected to the
corresponding signals in the other side in a one-to-one basis. A
crossover (null-modem) cable is used to connect two DTE directly,
without a modem in between. They cross transmit and receive data signals
between the two sides and there are many variations on how the other
control signals are wired, below is one of them:

RS-232 Signals
RS-232 Logic Waveform (8N1)The graphic above illustrates a typical RS-232 logic waveform (Data
format: 1 Start bit, 8 Data bits, No Parity, 1 Stop bit). The data
transmission starts with a Start bit, followed by the data bits (LSB
sent first and MSB sent last), and ends with a "Stop" bit.
The voltage of Logic "1" (Mark) is between -3VDC to -15VDC, while the Logic "0" (Space) is between +3VDC to +15VDC.
RS-232 connects the Ground of 2 different devices together, which is
the so-called "Unbalanced" connection. An unbalanced connection is more
susceptible to noise, and has a distance limitation of 50 ft (which is
around 15 meters).
Step 2: Learn about the Protocol
A protocol is one or a few sets of hardware and software rules agreed
to by all communication parties for exchanging data correctly and
efficiently.
Synchronous and Asynchronous Communications
Synchronous Communication requires the sender and receiver to share
the same clock. The sender provides a timing signal to the receiver so
that the receiver knows when to "read" the data. Synchronous
Communication generally has higher data rates and greater error-checking
capability. A printer is a form of Synchronous Communication.
Asynchronous Communication has no timing signal or clock. Instead, it
inserts Start / Stop bits into each byte of data to "synchronize" the
communication. As it uses less wires for communication (no clock
signals), Asynchronous Communication is simpler and more cost-effective.
RS-232 / RS-485 / RS-422 / TTL are the forms of Asynchronous
Communications.
Drilling Down: Bits and Bytes
Internal computer communications consists of digital electronics,
represented by only two conditions: ON or OFF. We represent these with
two numbers: 0 and 1, which in the binary system is termed a Bit.
A Byte consists of 8 bits, which represents decimal number 0 to 255,
or Hexadecimal number 0 to FF. As described above, a byte is the basic
unit of Asynchronous communications.
Baud rate, Data bits, Parity, and Stop bit
The baud rate is the communication speed that measures the number of
bit transfers per second. For example, 19200 baud is 19200 bits per
second.
Data bits are a measurement of the actual data bits in a
communication packet. For example, the above graphic shows eight (8)
data bits in a communication packet. A communication packet refers to a
single byte transfer, including Start / Stop bits, Data bits and Parity.
If you are transferring a standard ASCII code (0 to 127), 7 data bits
are enough. If it is an extended ASCII code (128 to 255), then 8 data
bits are required.
Parity is a simple way to error-check. There are Even, Odd, Mark and
Space indicators. You can also use no parity. For Even and Odd parity,
the serial port sets the parity bit (the last bit after the data bit) to
a value to ensure that the data packet has an Even or Odd number of
logic-high bits. For example, if the data is 10010010, for Even parity,
the serial port sets the parity bit as 1 to keep the number of
logic-high bits Even. For Odd parity, the parity bit is 0 so that the
number of logic-high bits is Odd. Mark parity simply sets the parity bit
to logic-high and Space sets the parity bit to logic-low, so that the
receiving party can determine if the data is corrupted.
Stop bits are used to signal the end of a communication packet. This
also helps to synchronize different clocks on the serial devices.
Handshaking (Flow Control)
Handshaking is also called "Flow Control". The main purpose of
Handshaking is to prevent receiver overloading. By using Handshaking
signals, receivers will be able to tell the sending device to pause data
transmission if the receiver is overloaded. There are three types of
handshaking: Software handshaking, Hardware handshaking and Both.
Software handshaking uses two control characters: XON and XOFF. The
receiver sends these control characters to pause transmitter during
communication. XON is decimal 17 and XOFF is decimal 19 in the ASCII
chart. The drawback of Software handshaking is that these two control
characters can not be used in data. This is quite important when you are
transmitting Binary data as you might need to use these two codes in
your data.
Hardware handshaking makes use of actual hardware lines, such as RTS / CTS, DTR / DSR, and DCD / RI (for modem).
In DTE / DCE communication, RTS (Request to Send) is an output on the
DTE and input on the DCE. CTS (Clear to Send) is the answering signal
coming from the DCE. Before sending a data, the DTE asks permission by
setting its RTS output to high. No data will be sent until the DCE
grants permission by using the CTS line. The DTE uses the DTR (Data
Terminal Ready) signal to indicate it is ready to accept information,
whereas the DCE uses the DSR signal for the same purpose. DTR/DSR are
normally ON or OFF for the whole connection session (e.g. Off-hook),
while RTS/CTS are ON or OFF for each data transmission. DCD (Data
Carrier Ready) is used by the modem when a connection has been
established with remote equipment, while RI (Ring Indicator) is used by
the modem to indicate a ring signal from telephone line.
Data formats (Binary, Hex, Dec, Oct, and ASCII)
Serial devices use Binary for communication, which consists of just two unique numbers: 0 and 1.
Binary is the Base-2 numbering system. One byte of data consists of 8
binary digits, from 0000 0000 to 1111 1111. Hexadecimal is the base-16
system, which consists of 16 numbers: 0 to 9 and the letters A to F
(decimal number 15).
The Hexadecimal numbering system is useful because it can represent
every byte as two consecutive hexadecimal digits, and it is easier for
humans to read Hexadecimal numbers than Binary numbers. Most of the
manufacturers use Hexadecimal in their protocol documentation. It is
simple to convert a value from Hexadecimal to Binary. Just translate
each Hexadecimal digit into its 4-bit binary equivalent. E.g.
Hexadecimal number F3 equals Binary number 1111 0011.
Decimal refers to numbers in base 10, which is the numbering system
we use most in everyday life. It's not as easy as Hexadecimal and Octal
to converter Decimal to Binary number, but it is easier for us to
understand Decimal.
Octal refers to the base-8 numbering system, which uses just eight
unique symbols (0 to 7). Programmers often use Octal format because it
is relatively easy for people to read and can easily be translated into
binary format: each Octal digit represents 3 binary digits. E.g. Octal
number 73 equals to Binary number 111 011.
ASCII (American Standard Code for Information Interchange) is a
character encoding based on the English alphabet. ASCII codes (both
readable and unreadable) are widely used in communications, such as
Modem communications. Letters A to Z and numbers 0 to 9 are readable
ASCII codes. Some ASCII codes are unreadable, such as the control codes:
XON and XOFF, which are used in Software flow control.
Checksum
Many serial protocols use checksum (additional bytes added at the end
of the data string) to check the data integrity, as errors might occur
during data transmission. There are many types of checksum, from the
simplest uses of it in Modula or BCC to sophisticated CRC calculation.
Using Modula as an example, we learn that before data transmission, the
sender adds all command bytes together then mod it by 255 (decimal) to
get an additional byte. This is to be added at the end of the command
string. When the receiver receives the command string, it will first
check the added byte to see whether data remain unchanged or not. If
that is the case, it will accept the data, and if not, it will ask the
sender to resend the data.
Examples of protocol commands
A protocol command is a data string sent from one serial device (e.g.
a Computer) to another (i.e. a Modem). Here are some examples:
ASCII command example: ATI1 to query Modem manufacturer's information. (Note: are the control codes of Carriage Return and Line Feed).
Convert the command string above to Hexadecimal and it becomes: 41 54 49 31 0D 0A
Convert the command string above to Decimal and it becomes: 065 084 073 049 013 010
Convert the command string above to Octal and it becomes: 101 124 111 061 015 012
Convert the command string above to Binary and it becomes: 01000001 01010100 01001001 00110001 00001101 00001010
Step 3: Control your RS232 devices by using 232Analyzer
232Analyzer is an Advanced Serial Port Protocol Analyzer software,
which allows you to control / debug, monitor / sniff serial devices
(RS-232 / RS-485 / RS-422 / TTL) right from your PC. 232Analyzer is a
shareware, the FREE version has some limitation but is more than enough
to test and control your serial devices. Click here to download a FREE copy.
Checksum calculation
232Analyzer comes with a Checksum calculator, which allows you to
calculate the complicated checksum byte in seconds, here is an example:
Suppose that you are controlling a projector, and the projector
protocol uses xOR to get the additional checksum byte, the command
string to turn ON the projector is: "1A 2B 3C" plus the Checksum byte.
Use the following procedures to calculate the Checksum byte:
Select Hex as an operands format
Select xOr as an operator
Key in the command string and append a comma (,) after each byte of command code: e.g. 1A,2B,3C,
Click on the "Calculate" button and you will get the result of 0D (0 is omitted)
Select COM port and Setup communication formats
From the above toolbar example, the COM port connected to the
projector has been set as: COM port: 5, Baud Rate: 19,200 bps, Data bit:
8, Parity: Even, Stop bit: 1.
Note: After you have set up the correct communication formats (they
must match with the projector's COM port settings), click on the
"Connect" button on the left to activate the COM port.
Flow control settings
Flow control can be set from the window above. Either Software (XON /
XOFF), Hardware (RTS / CTS), Both (Software + Hardware), or None can be
selected.
Control your RS232 devices
Control / Monitor Line States
232Analyzer allows you to control / monitor line states of your COM ports.
Line states of RTS and DTR will be toggled when the respective LED
is clicked, you can use a voltage-meter to verify the changes, you
should get +6V to +15V when the line state is ON, and -6V to -15V when
the line state is OFF.
Other line states can be monitored through the Virtual Ds, such as RX, TX, DSR, CTS, DCD and RI.
Send / Receive commands
Use the above example to control a projector (turn ON the projector),
key in the complete command string "1A,2B,3C,0D," into the
Send_Command_Pane as shown above, and then click on the "Send" button...
Notes:
In the FREE version, Hex mode is not available. You can use Decimal format to send out the command string: "26,43,60,13,"
You can use any RS-232 device for testing, as long as you know the protocol commands.

Best 1TB USB Drive
Capacity: 1TB | Interface: USB 3.1
If you are looking in the premium territory of the best USB flash drives, then the Samsung T3 is worth taking a look at. Not only does it offer absurdly high read speeds of up to 450Mbps thanks to Samsung's own 3D V-NAND technology, but it also comes with a three-year warranty and has a USB Type C connector.
Note that it is much bigger than a traditional flash drive and it does cost about five times a traditional hard drive of a similar capacity. In comparison, a 1TB SSD like the Samsung EVO 850 costs just £240. It comes with V-NAND like the Samsung Portable T1 and it does boast speeds of 530Mbps and 520Mbps in read/write mode respectively.

Small and unobtrusive
Capacity: 32GB | Interface: USB 3.0
If you don't want a USB stick jutting out the side of your laptop or tablet while you use it or having one is simple not ideal – for example, when you’re using it while traveling, then a low-profile USB stick is an excellent choice. Take the SanDisk Ultra Fit CZ43. It’s small and light enough to easily carry around. And, when it's plugged into your laptop, it doesn't stick out much from the body, making it more secure when you’re using it on the go.
That’s not all; it’s also very cheap, at around £10 for the 32GB version, with 64GB and 128GB versions also available. It's not quite as fast as many of the best USB flash drives we mentioned here, but if you want a small form factor USB stick, it's worth the trade-off.
How to choose your USB pendrive?
It's not worth looking for memory sticks smaller than 64GB simply because the price difference you pay for two or four times the storage is tiny.
Make sure you include delivery price when doing the numbers as quite often you end up paying more for the postage than the drive itself, particularly for low cost models.
USB 2.0 is sufficient for smaller capacities but not for bigger ones where write speeds can get sluggish. Larger pendrives (128GB or more) often come only with a USB 3.0 connector.
If you plan on moving files to and from portable devices (tablets or smartphones), consider a memory stick with a microUSB connector and a full-size USB one.
Avoid buying your memory sticks from vendors with little feedback on auction websites as these drives might turn out to be fake. All the vendors listed are tried and trusted ones.
Above 128GB, you might want to consider a SSD if you want ruggedness, portability, versatility and better performance without the cost.
Note that the capacities are likely to be lower than stated when they are formatted and mounted on an operating system.
