<span>Slow shutter speeds allow more light into the camera sensor and are used for low-light and night photography, while fast shutter speeds help to freeze motion. Examples of shutter speeds: 1/15 (1/15th of a second), 1/30, 1/60, 1/125. Aperture – a hole within a lens, through which light travels into the camera body.
Hope this helps : )

Let us examine the given answers.
a) Google yourself regularly, and monitor what your friends post.
Verdict: This answer is correct, but it is also necessary to look for yourself on other search engines.
b) Google yourself once a year
Verdict: Once a year is better than doing nothing, but more than once a year is preferable.
c) Google yourself every five years.
Verdict: The time interval is too long. Your reputation could easily be damaged, or your identity could be stolen in less than 5 years.
d) Delete all your accounts and start fresh.
Verdict: This will not solve the problem of having your reputation damaged, or having your identity stolen. Information on the web is preserved ins storage vaults for long periods of time.
Answer:
Google yourself regularly, and monitor what your friends post. Also, search for your name on other search engines.
Answer:
The best answer is "A"
Explanation:
With non-static interface methods, helper methods can now be declared directly in interfaces rather than in separate classes.
Answer:
Explanation:
In data communications, a protocol is <em>connectionless </em>if it describes communication between two devices in a network without first establishing or verifying establishment of some link (connection) between the two devices. In a connectionless protocol, data are exchanged between processes or devices without a prior check of whether the processes are ready to transmit data or not. In this type of protocol, there's no verification put in place to remember if these processes were or are in communication. Connectionless protocols are also called stateless protocols. Because connectionless protocol cannot be relied upon due to its lack of delivery-assurance policy, it is sometimes referred to as <em>unreliable protocol</em>. In other words, delivery of data packets is not guaranteed. An example of a connectionless protocol is the UDP (User Datagram Protocol).
However, if the protocol defines some checks to ascertain that there is first a connection between two communicating processes before beginning transmission, then, the protocol is <em>connection-oriented. </em>An example of this is the TCP (Transmission Control Protocol). Connection-oriented protocols are reliable since they ensure connection be made between processes before transmitting data packets.
A typical application of a connectionless/unreliable protocol is in the streaming of real time videos or voice communication where packets of data could be dropped and not resent.
An example of the connection-oriented/reliable protocol is analogous to making a telephone call where data packets (voice messages) are not sent until the receiver on the other end makes a connection.
