Software: Software is a group of instructions and related documentation that informs a computer “what to do or how to perform a task”. Software is divided into two following categories. System software Application software System software: It is used to control and manage the basic computer operations and it is referred as “system software”. It includes the following program types: Operating Systems: It is used to control the internal operations of the computer’s hardware, managing computer devices and allowing users to perform data manipulations from storage devices, etc. Utility Programs: It is used to perform a special task that improves the computer’s operation. Programs like data backup, virus scanners and file compression are the examples. Software Development Tools: Tools that help the programmer to create, test and modify software are referred as Software development tools. Application Software: Application software or applications are referred as productivity programs; because, they allow users to complete their task. Examples: Document creation, databases , etc. This software is designed to do a specific task. It might be simple or complex that depends on the application used.

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

⚫ 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…
