Consider the following pushdown automata (pda) where s is the starting state and f is the favorable state:

(s, a, aa) ? (s, a); (s, a, ? ) ? (s, a); (s, b, a) ? (f, ? ); (f, b, a) ? (f, ? ); (f, a, a) ? (f, ? )

give the computation of the pda (give the state, input string still to be read, and top of the stack symbol (a, b, ? ) on the string aaabba, abbaaa, and baba. determine which of the strings are accepted by the pda.
determine the language accepted by the pda.

Design a pos circuit that displays the letters a through j on a seven-segment indicator. the circuit has four inputs w, x, y, and z which represent the last 4 bits of the uppercase ascii code for the letter to be displayed. thus, if wxyz = 0001 then "a" will be displayed. (any answer with 22 or fewer gates and inverters, not counting any for the inputs, is acceptable)

You have just been hired as an information security engineer for a large, multi-international corporation. unfortunately, your company has suffered multiple security breaches that have threatened customers' trust in the fact that their confidential data and financial assets are private and secured. credit-card information was compromised by an attack that infiltrated the network through a vulnerable wireless connection within the organization. the other breach was an inside job where personal data was stolen because of weak access-control policies within the organization that allowed an unauthorized individual access to valuable data. your job is to develop a risk-management policy that addresses the two security breaches and how to mitigate these risks.requirementswrite a brief description of the case study. it requires two to three pages, based upon the apa style of writing. use transition words; a thesis statement; an introduction, body, and conclusion; and a reference page with at least two references. use a double-spaced, arial font, size 12.
