Question
Chapter 9, Problem 1CTQ
Program Plan Intro
- OS is the term that acts as an interface between the hardware and the user.
- OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files.
Windows OS tools:
- Firewall
- It monitors and controls the traffic on network in the system.
- It acts as a barrier between the system and unauthorized users.
- Antivirus software
- It is used for identifying, preventing and deleting the errors in the system.
- Spyware
- It helps the unauthorized users like hacker to get access to the system.
- Malware detection software
- It is used for identifying, preventing and deleting the malware present in the system.
- Automatic updating
- It helps in updating the software without including the user permission.
Explanation of Solution
Security concerns related to built-in OS tools:
“Yes” the built-in OS tools include the security concerns.
Reason:
Window...
Explanation of Solution
Alternatives:
- Encryption
- Encryption is the term used to define the process which helps protect the unauthorized access to data.
- The data is hidden using some mathematical
algorithms. - It helps to protect data during transmission of data over a network and the data stored in
databases are protected.
- Authentication
- Authentication sequence or digital signatures are used in securing many financial transactions...
Explanation of Solution
Disability of Windows tool:

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:

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.
