Explanation of Solution
Security threats:
Security threat is a thing that can cause damage to the organization, IT systems and networks. For example, if the details of a bank account can be accessed by any intruder without the permission of an appropriate user for misusing their details is called as “threat”.
Explanation for elements that are given in “Figure 10-6”:
- If important data is involved in system then security measures have to be taken seriously to protect the data.
- Creating strong password for particular site and multiple passwords for different account is to keep hackers from accessing accounts more easily.
- Sending data via email or IM is not secure because hackers can easily hack those information using history logs.
- HTTPS is a hypertext transfer protocol for secure transformation or communication over the web.
- Removing high value of asset from computer is a way to keep our system safely.
- Hacker knows the information through browsing history, temporary files, and cookies of the system. So, clear all the visited files to prevent the system.
- Updating antivirus software is an essential thing to keep the system from threat.
- Security concern is an important for every worker so that everyone is on the same page when it comes to privacy.
- Following the guidelines of the company in order to reduce the chance of a threat.
- Business initiatives must consider this protection activity that would ensure the organization-wide.
IDS:
Intrusion detection system (IDS) is an application software or device which is used to monitor the networks or activities of the system for unauthorized access and threats to produce the caution reports to authorized user...

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:

- Programming Problems 9.28 Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1.
