How to quickly detect and judge whether the USB flash drive is infected with the virus under Win7 Ultimate system?

 Nowadays, USB disks are used more and more widely, not only can store and copy data, but also install systems, but various problems will also occur during use. USB disk poisoning is a more serious problem, so how to detect Is there a virus in USB disk? Let's take the Win7 flagship system as an example to tell you about it.

How to quickly detect and judge whether the USB flash drive is infected
Step by Step  

method:

　　1. The original folder stored in the USB  disk suddenly disappeared. This may be caused by a pseudo-folder U disk virus.

　　2. Right-click the letter of the USB disk, and commands such as "AutoPlay", "Brower" or "Open" have been added to the menu.

　　3. All files in the USB disk have become .exe format files and cannot be opened normally.

　　4. After the USB disk is plugged into the computer, it will take a long time to be recognized by the win7 system computer.

　　5. When double-clicking the USB disk under win7 system, the  USB disk directory cannot be opened, even if it is opened, other disk directories are opened.

　　6. There are a lot of files with strange names in the USB disk directory for no reason.

　　7. Folders cannot be copied to the USB disk. Even if they are copied, they cannot be opened. Perhaps the folder is infected and replaced with a virus after being hidden. What you are copying is actually a virus program.

　　The above is about the method of quickly detecting and judging whether the USB flash drive is poisoned under the Win7 Ultimate system. In order to prevent the virus from the USB flash drive from spreading freely, if the above signs are found using the USB flash drive, take precautions.

Defination of the essential properties of operating systems

Define the essential properties of the following types of operating sys-tems: Batch Interactive Time sharing Real time Network Parallel Distributed Clustered Handheld ANSWERS: a. Batch processing:- Jobs with similar needs are batched together and run through the computer as a group by an operator or automatic job sequencer. Performance is increased by attempting to keep CPU and I/O devices busy at all times through buffering, off-line operation, spooling, and multi-programming. Batch is good for executing large jobs that need little interaction; it can be submitted and picked up later. b. Interactive System:- This system is composed of many short transactions where the results of the next transaction may be unpredictable. Response time needs to be short (seconds) since the user submits and waits for the result. c. Time sharing:- This systems uses CPU scheduling and multipro-gramming to provide economical interactive use of a system. The CPU switches rapidl

What is a Fair lock in multithreading?

Photo by João Jesus from Pexels In Java, there is a class ReentrantLock that is used for implementing Fair lock. This class accepts optional parameter fairness. When fairness is set to true, the RenentrantLock will give access to the longest waiting thread. The most popular use of Fair lock is in avoiding thread starvation. Since longest waiting threads are always given priority in case of contention, no thread can starve. The downside of Fair lock is the low throughput of the program. Since low priority or slow threads are getting locks multiple times, it leads to slower execution of a program. The only exception to a Fair lock is tryLock() method of ReentrantLock. This method does not honor the value of the fairness parameter.

How do clustered systems differ from multiprocessor systems? What is required for two machines belonging to a cluster to cooperate to provide a highly available service?

How do clustered systems differ from multiprocessor systems? What is required for two machines belonging to a cluster to cooperate to provide a highly available service? Answer: Clustered systems are typically constructed by combining multiple computers into a single system to perform a computational task distributed across the cluster. Multiprocessor systems on the other hand could be a single physical entity comprising of multiple CPUs. A clustered system is less tightly coupled than a multiprocessor system. Clustered systems communicate using messages, while processors in a multiprocessor system could communicate using shared memory. In order for two machines to provide a highly available service, the state on the two machines should be replicated and should be consistently updated. When one of the machines fails, the other could then take‐over the functionality of the failed machine. Some computer systems do not provide a privileged mode of operation in hardware.
