Synchronous Transfer Synchronous transmission is the data transfer in units of data frames. Frame synchronization signals in the form of characters or bit combinations can be used. The transmitter or receiver provides a clock signal dedicated to synchronization. In short-distance high-speed large file transfer, the clock signal can be transmitted by a dedicated clock line. When the computer network adopts the synchronous transmission method, the clock synchronization signal is often embedded in the data signal frame to achieve clock synchronization between the receiver and the transmitter. In digital communication, synchronization is very important. When the transmitter transmits data information to the receiver through the transmission medium, for example, each time a character data signal is sent, the receiver must recognize the start bit and end bit of the character data signal. To correctly read each bit of the data signal of the character at the appropriate time, this is the basic synchronization problem between the receiver and the transmitter. When sengding data signals in data frames, to ensure the integrity and accuracy of the transmitted signal, in addition to requiring the receiver to be able to recognize the start and end of the signal corresponding to each character , to ensure that the reading starts and ends at the correct time Retrieving the signal means maintaining the integrity of the transmitted signal. It is also required to keep the clock and the transmitter at the same frequency to ensure that the number of signal units reads per unit time is the same, that is, to ensure the accuracy of the transmitted signal. Therefore, when transferring data signals in data frames, the transmitter is required to take the following two measures for the transmitted signals: ①Add a start signal and a stop signal different from the data signal before and after the corresponding signal of each frame of data; ② Add a clock synchronization signal before the data signal of each frame to control the clock synchronization of the receiver. Asynchronous Transmission Asynchronous transmission is the transmission of data in units of characters, using character synchronization signals in the form of bits. The transmitter and receiver have independent clocks , and neither side provides clock synchronization signals to the other side. The sender and receiver of the asynchronous transmission do not need to coordinate before the data can be transmitted: the sender can move data at any time, and the receiver must be ready to receive data at any time. The asynchronous transmission mode is generally adopted between the computer host and the input and output devices. Such as a keyboard, a typical RS-232 serial port : the sender can send a character at any time . The Advantages and Disadvantages of Asynchronous and Synchronous Data Transmission 1. Asynchronous transmission is the character-oriented transmission, while the synchronous transmission is bit-oriented. 2. The unit of asynchronous transmission is character and the unit of synchronous transmission is a frame. 3. Asynchronous transmission seizes the opportunity of re-synchronization through the start and stops codes of character start and end, while synchronous transmission extracts synchronization information from the data. 4. The asynchronous transmission has lower requirements on timing, and synchronous transmission often coordinates timing through a specific clock line. 5. Asynchronous transmission is less efficient than synchronous transmission. To Sum Up Both asynchronous transmission and synchronous transmission have the above basic synchronization problem: character synchronization or frame synchronization signals are generally used to identify the start and end of transmitting character signals or data frame signals. The main difference between the two is whether one of the transmitter or receiver sends a clock synchronization signal to the other party.

File synchronization is the process of ensuring that computer files in two or more locations are updated by certain rules. About file synchronization In one-way file synchronization , the updated files are copied from the "source" location to one or more "target" locations, but no files are copied back to the source location. In two-way file synchronization, updated files are copied in both directions, usually to keep the two locations the same. Nowadays, general file synchronization usually refers to two-way file synchronization. The general file synchronization system has the following functions: Encryption to ensure security, especially when compressing any data sent through the network when synchronizing via the Internet. Conflict detection modifies the location of the file on two sources instead of on one source. Undetected conflicts may result in overwriting the copy of the file with the latest version, resulting in data loss. For conflict detection, the synchronization software needs to keep a database of synchronized files. Distributed conflict detection can use the version vector to copy the data or application files in use or exclusively locked database files, "open file support" can ensure data integrity; Especially supports the use of intermediate storage devices to synchronize two computers. Most synchronization programs can be used in this way, but providing specific support for this can reduce the amount of data stored on the device;The ability to preview any changes before the change; The ability to view the differences in individual files; Backups between operating systems and Transmission between network computers; At present, more and more people have multiple intelligent terminal devices, which greatly facilitates people's work and life. The popularization of intelligent terminal equipment brings convenience to people but also brings new challenges to people's file management. How to ensure data consistency among multiple devices and how to efficiently synchronize files have become the focus of attention. When we want to process some work files when we get home, file synchronization can play a great role, and we can process work things at home just like in a company. Methods of file synchronization Tools used for file synchronization are, for example, Raysync, FreeFileSync, Syncthing, Dropbox, FileGee, GoodSync, etc. Let's look at a few of these methods! Raysync Enterprise-level Reliability Raysync can transfer large files on a full-bandwidth basis, which allows organizations to transfer files intact over any distance and network environment Mass-scale Synchronization It leverages the architecture to synchronize millions of small files or petabytes-sized files, and supports multiple concurrent sessions, clusters and 10 Gigabit transmission speed. Efficient Synchronization Efficient identification of file update status to avoid retransmission of the same file and reduce unnecessary synchronization Flexible Configuration Support Multiple Operations: one-way and two-way synchronization, timed synchronization, encrypted or unencrypted, keep modification time, transfer only source files, synchronized deletion, etc. Syncthing The biggest feature is the use of P2P distributed technology similar to Resilio Sync , which allows multiple devices to synchronize files with each other in real-time without a central server. The function is very close to Resilio Sync / BT Sync, but it says It seems to be a server software or cloud storage service application used to build network disks. Compared to server tools such as Seafile and NextCloud, Syncthing is actually more like a file/folder synchronization tool. Dropbox It is a free network file synchronization tool. It is an online storage service operated by Dropbox. It synchronizes files on the Internet through cloud computing. Users can store and share files and folders. Dropbox provides free and paid services. Dropbox's paid services include Dropbox Pro and Dropbox for Business. There is client software under different operating systems, and there are web clients. Realizing the safe synchronization of files can reduce the time spent on file backup and storage for freelancers and independent employees. The version backtracking function provides unparalleled convenience for some misoperations or version comparison. So that workers can focus more on work instead of documents. For enterprises, file synchronization is more convenient for managers to understand and control the progress of the entire project.

What is the file synchronization service? File synchronization is a method of keeping files that are stored in several different physical locations up to date. It has grown increasingly important as enterprises use the cloud as a means for collaboration. It is also commonly used for backup and for mobile access to files. File syncing software is used to store copies of on-premises data to another device or to the cloud. The files are typically available to be accessed via a Web-based portal. Some examples of file sync software include Raysync, Box, Syncplicity, and Dropbox. There are two types of file sync: One-way synchronization pushes files from your source platform to the destination system. On the other hand, two-way synchronization pushes and pulls files in both directions, from both systems. In one-way sync, files are copied only from a primary location to a secondary location in one direction, but no files are ever copied back to the primary location. Replication and Backup are one-way sync methods in ViceVersa. In two-way sync, ViceVersa copies files in both directions, keeping the two locations in sync with each other. Synchronization and Consolidation are two-way sync methods in ViceVersa. How file synchronization works and how to implement it? How you implement file synchronization will depend on your needs. And there are several file syncing techniques you can use. These can include using a hosted system, using a third-party tool, and creating your own sync system for instance. The best file-syncing solutions provide a simple solution to copy and back up your files from different devices, whether you are at work, at home, or on the go. In addition to storing and syncing data, most syncing solutions also come with additional tools not just for managing your saved data but also for managing user access and permissions, to allow for file sharing and collaboration with stored files. In this artile, we feature what we think are the best file-syncing solutions currently available. GoodSync GoodSync is an established company that provides file synchronization and backup software services. Set up is easy, and just requires you to install the software, select target files and folders, then set up automation functions for backups and syncing. And that's pretty much it. The simplicity of use hides the fact that this is a powerful solution that comes in a couple of different forms. One is GoodSync ServerOS which provides backups and synchronization for Windows and Linux servers. The other is the GoodSync File Server, which allows specified files and folders to be backed up and synced to a private cloud, with various rules and automation options available to ensure everything is easily managed. Resilio Sync Resilio Sync has an interesting background story: it was spun out of BitTorrent Inc, which means that it has peer-to-peer technology as part of its DNA. P2P is a tried and trusted protocol that is particularly useful for sending large files swiftly. It is one of the very few services that is compatible with Linux as well as a slew of Network Attached Storage solutions . Unlike most of what we’ve covered here, Resilio Sync is not a cloud-based file syncing solution. Instead, it relies on devices connected in peer-to-peer mode for the syncing process. There’s a free version and a paid offering which links all your devices, has a one-time send feature, a selective sync feature and the ability to add folders to all your devices automatically. You will need to install this on all devices that you want to sync between. Raysync File sync means that a local folder is designated as a synchronized folder. By creating, copying, pasting, modifying, and deleting files in the synchronized folder, the system will automatically update the changed files synchronously, so that the local files in the synchronized folder are always consistent with the folder stored in the cloud. Raysync file synchronization function, through the core technologies independently researched and developed, such as high-speed engine technology and high-speed transfer protocol technology, establishes a data synchronization solution in line with the business scenarios of enterprise users. Tutorial of Raysync file synchronization: 1. Select the files to be synchronized, and click to create the sync folder task. 2.

Synchronization time can be set according to specific requirements, for example, you can set synchronization every 1 second; You can also set synchronization at a certain point in time, such as 10 am every day. Now, file sync only once is also available in sync schedule setting. Conclusion Good tools can effectively improve the efficiency of the transfer, file syncing in time can be fast and accurate to convey information, but also as a backup channel. Raysync has excellent features in file synchronization, which is a software for data transfer and file synchronization.

There was a time when everyone was used to working in an office or at home-basically in one place. However, with the advent of smartphones, laptops, tablets, and other smart devices, the workplace has transcended boundaries. The only thing that can prevent you from working from almost anywhere now is the inability to access work data. File synchronization is a technology designed to solve this problem by accessing data across multiple systems and platforms. File synchronization refers to the process of updating data files across multiple devices in real-time. More than one person can work on the same file or project in different locations, even if they are miles apart. There are two types of file synchronization processes: one-way and two-way file synchronization. In one-way file synchronization, data files are updated from a single source to multiple target locations and platforms. But no data is stored back to the source. In two-way file synchronization, various locations and platforms work together, and two-way communication is established between each pair in the system. Most people confuse file synchronization and backup, but the two are completely different processes. One of them cannot replace the other, and in most cases, you need to rely on both of them. In file synchronization, the same data is updated across multiple locations and platforms. It allows the team to work on one project without having to be in one place. The concept behind this is that every time a file is saved on a device, it will be uploaded to the server online. Then the system connected to the network constantly checks for file updates and downloads files when newer versions are available. On the other hand, backup is primarily a way for companies to protect data by copying information from one location to another. For example, you can copy the contents of a laptop to an external drive. The backup data will not be accessed by anyone for any collaborative work but is kept in one place so that it can be used to restore the system in the event of any crash. Backup is only to protect data assets and ensure business continuity without any major troubles. File synchronization is indeed the gospel of working on multiple devices at the same time. People can use file synchronization to collaborate completely flexibly without relying on the inconvenient back and forth e-mails. File synchronization and file backup: what is the difference?

In this digital age with advanced technology, people always hope to share files and move data quickly through the flexible movement of the mouse. From server to server, from the test environment to quality assurance, from one data center to another. In fact, despite the use of a hybrid cloud environment, the efficiency and security of file sharing still worry enterprises. Even if an accurate plan is designed, it is always possible that the value of files will be devalued due to transfer efficiency problems, and data leakage will be caused by the uncontrollable transfer. File-sharing with only one click This sounds very simple, but in practice, you will find that a large number of components and IT technologies based on file-sharing are needed. Speed is thr top technology Speed is the basis of mining the value of file sharing.

The globalization trend of enterprises is becoming more and more obvious, and there are more and more cross-regional and transnational groups. The structure of these groups is characterized by dispersion, which may be headquartered in Beijing, China, and its branches in the United States, Australia, France, and other places. Headquarters needs to synchronize documents such as publicity materials, R&D data, and design manuscripts to all branches. Nowadays, many enterprises try to use FTP to solve the problem of file synchronization. However, there is a problem in using FTP to synchronize enterprise files, that is, enterprises need to arrange manpower to upload files regularly and then arrange others to download them, which wastes manpower and time. Free synchronization tools are also the choice of many companies, but they need certain operation and maintenance capabilities. This type of file synchronization software is prone to errors in the use process, and troubleshooting errors is a labor-consuming and time-consuming project. In addition, this kind of file synchronization software still has certain security risks, and the security of enterprise core data assets should not be underestimated.
