#1) Which is faster, a hi-speed usb port or a superspeed usb port?
Answer: superspeed usb port. USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS) that can transfer data at up to 5 Gbit/s thats 625 MB/s.
A computer uses unallocated space also know as free space to keep a file that has been deleted in its disk until a new file takes it spot and overwrites it.
Answer:
Synchronous data transmission is a data transfer method in which a continuous stream of data signals is accompanied by timing signals (generated by an electronic clock) to ensure that the transmitter and the receiver are in step (synchronized) with one another. The data is sent in blocks (called frames or packets) spaced by fixed time intervals.
Answer:
Option b is the correct answer for the above question.
Explanation:
Thrashing occurs when the virtual memory of the computer is more used. It is because the system does not have more memory. That's why the virtual memory is busy in the paging or other work of the operating system and there is no memory left for the other useful work of the system and then Thrashing occurs.
The question statement states the same which is described above and this is the cause when thrashing occurs. Hence the b option is correct. while other is not because--
- Option "a" states about spooling but spooling is a concept of copy the data.
- Option C states about an interrupt but it is a concept to stop the work of CPU when any input is coming from the outside.
- Option D states about a pooling signal which is an operation of computers.
A feature that preserves open apps and data while allowing another user to log in to his or her own session of the same computer is: switch user.
<h3>What is a computer?</h3>
A computer is an electronic device that is designed and developed to receive data from an end user in its raw form (input) and processes these data into an output that could be used for other purposes.
Generally, all computers are designed and developed with a feature called switch user, so as to preserve open software applications and data while allowing another user to log in to his or her own session of the same computer simultaneously.
