Answer:
C. Symptoms of malware mutation
Explanation:
They are signs that could indicate that ones system is infected by virus.
Such signs includes:
1.Slow booting or startup.
2.Low space storage.
3.Blue screen of death.
4.Slow Internet performance.
5.Sending of spam messages.
6.Disabled security.
7.Browsing error.
8.Pop-up messages.
9.Renaming of files.
10.Loss of certain files, music, messages, etc.
Answer:
The advantage of the simulated link strategy are:
- It is easily able to provide the practical feedback to the customers and users while designing the whole system. It also determine the efficiency and the correctness of the design in the stimulated link strategy.
- In the stimulated link strategy, the sharing and delivering of the data and information is done efficiently without any occurrence of error and interrupt. It is also high flexible technique.
The disadvantage of the simulated link strategy are:
- The simulated link strategy is flexible but it is not standardization and also it required more good concept.
- This technique is expensive and it is not readily available as it always require validation process.
Use the following rules:
- The sum of currents that enter and exit a node (junction) is always zero. So if you have 3 wires that connect, through one flows 2A, the other 3A, then the third must deliver 5A (taking the direction into account!)
- The sum of voltages across different components should always add up. So if you have a battery of 10V with two unknown resistors, and over one of the resistors is 4V, you know the other one has the remaining 6V.
- With resistors, V=I*R must hold.
With these basic rules you should get a long way!
Most computers have three types of ports: serial, parallel, and USB. A serial port is a type of interface that connects a device to the system unit by transmitting data only one bit at a time. Serial ports usually connect devices that do not require fast data transmission rates, such as a mouse, keyboard, or modem.
Answer:
Lossy image formats will remove data during compression as a trade off for lower storage occupation. Lossless data formats will not remove data during compression, resulting in higher quality but also higher storage occupation.
Graphic Artists will almost always use lossless due to it delivering the highest quality image possible.
