The “AND” operator: The symbol ampersand (&) is used to represent logical operator AND. The AND operator is used as the logical conjunction on two expressions. The AND operator returns true if both its operands are true and false otherwise. The “OR” operator: The symbol “||” is used to represent logical operator OR. The OR operator returns true if one of its operand is true and false if both the operands are false. The logical OR has left-to-right associatively.

Question

Create 6 users: Don, Liz, Shamir, Jose, Kate, and Sal. Create 2 groups: marketing and research. Add Shamir, Jose, and Kate to the marketing group. Add Don, Liz, and Sal to the research group. Create a shared directory for each group. Create two files to put into each directory: spreadsheetJanuary.txt meetingNotes.txt Assign access permissions to the directories: Groups should have Read+Write access Leave owner permissions as they are “Everyone else” should not have any access Submit for grade: Screenshot of /etc/passwd contents showing your new users Screenshot of /etc/group contents showing new groups with their members Screenshot of shared directories you created with files and permissions

Program Plan Intro

The “AND” operator:

The symbol ampersand (&) is used to represent logical operator AND.

The AND operator is used as the logical conjunction on two expressions.

The AND operator returns true if both its operands are true and false otherwise.

The “OR” operator:

The symbol “||” is used to represent logical operator OR.

The OR operator returns true if one of its operand is true and false if both the operands are false.

The logical OR has left-to-right associatively.

⚫ your circuit diagrams for your basic bricks, such as AND, OR, XOR gates and 1 bit multiplexers, ⚫ your circuit diagrams for your extended full adder, designed in Section 1 and ⚫ your circuit diagrams for your 8-bit arithmetical-logical unit, designed in Section 2. 1 An Extended Full Adder In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…
