QUES: Older operating systems such as TOPS-10, along with CP/M, tracked file length only in units of disk blocks and used Control-Z (SUB) to mark the end of the actual text in the file. For this reason, EOF, or end-of-file, was used colloquially and conventionally as a three-letter acronym for Control-Z instead of SUBstitute. The end-of-text code (ETX), also known as Control-C, was inappropriate for a variety of reasons, while using Z as the control code to end a file is analogous to it ending the alphabet and serves as a very convenient mnemonic aid. A historically common and still prevalent convention uses the ETX code convention to interrupt and halt a program via an input data stream, usually from a keyboard.
What is still the conventional use of the ETX code?

ANS: to interrupt and halt a program via an input data stream, usually from a keyboard

QUES: The Twilight Zone Tower of Terror is the common name for a series of elevator attractions at the Disney's Hollywood Studios park in Orlando, the Disney California Adventure Park park in Anaheim, the Walt Disney Studios Park in Paris and the Tokyo DisneySea park in Tokyo. The central element of this attraction is a simulated free-fall achieved through the use of a high-speed elevator system. For safety reasons, passengers are seated and secured in their seats rather than standing. Unlike most traction elevators, the elevator car and counterweight are joined using a rail system in a continuous loop running through both the top and the bottom of the drop shaft. This allows the drive motor to pull down on the elevator car from underneath, resulting in downward acceleration greater than that of normal gravity. The high-speed drive motor is used to rapidly lift the elevator as well.
What unique feature does this ride provide guests?

ANS: downward acceleration greater than that of normal gravity

QUES: In 2013 and 2014, a Russian/Ukrainian hacking ring known as "Rescator" broke into Target Corporation computers in 2013, stealing roughly 40 million credit cards, and then Home Depot computers in 2014, stealing between 53 and 56 million credit card numbers. Warnings were delivered at both corporations, but ignored; physical security breaches using self checkout machines are believed to have played a large role. "The malware utilized is absolutely unsophisticated and uninteresting," says Jim Walter, director of threat intelligence operations at security technology company McAfee – meaning that the heists could have easily been stopped by existing antivirus software had administrators responded to the warnings. The size of the thefts has resulted in major attention from state and Federal United States authorities and the investigation is ongoing.
What was the main breach? 

ANS: unanswerable

QUES: Apollo was worshipped as Actiacus (/ækˈtaɪ.əkəs/ ak-TY-ə-kəs; Ἄκτιακός, Aktiakos, literally "Actian"), Delphinius (/dɛlˈfɪniəs/ del-FIN-ee-əs; Δελφίνιος, Delphinios, literally "Delphic"), and Pythius (/ˈpɪθiəs/ PITH-ee-əs; Πύθιος, Puthios, from Πυθώ, Pythō, the area around Delphi), after Actium (Ἄκτιον) and Delphi (Δελφοί) respectively, two of his principal places of worship. An etiology in the Homeric hymns associated the epithet "Delphinius" with dolphins. He was worshipped as Acraephius (/əˈkriːfiəs/ ə-KREE-fee-əs; Ἀκραιφιος,[clarification needed] Akraiphios, literally "Acraephian") or Acraephiaeus (/əˌkriːfiˈiːəs/ ə-KREE-fee-EE-əs; Ἀκραιφιαίος, Akraiphiaios, literally "Acraephian") in the Boeotian town of Acraephia (Ἀκραιφία), reputedly founded by his son Acraepheus; and as Smintheus (/ˈsmɪnθjuːs/ SMIN-thews; Σμινθεύς, Smintheus, "Sminthian"—that is, "of the town of Sminthos or Sminthe") near the Troad town of Hamaxitus. The epithet "Smintheus" has historically been confused with σμίνθος, "mouse", in association with Apollo's role as a god of disease. For this he was also known as Parnopius (/pɑːrˈnoʊpiəs/ par-NOH-pee-əs; Παρνόπιος, Parnopios, from πάρνοψ, "locust") and to the Romans as Culicarius (/ˌkjuːlᵻˈkæriəs/ KEW-li-KARR-ee-əs; from Latin culicārius, "of midges").
The epithet Delphinius is associated with what animal?

ANS:
dolphins
