Question 1 Report
What is the function of firewall?
Answer Details
A firewall is a type of cybersecurity tool that helps protect a computer or network from unauthorized access or malicious activity from the internet. Think of a firewall as a security guard that stands at the entrance to your network, examining all incoming and outgoing traffic. It examines each packet of data to see if it meets certain criteria, such as the source and destination of the data, and the type of data being transmitted. If the packet meets the criteria, it's allowed to pass through the firewall and reach its destination. If it doesn't meet the criteria, the firewall blocks the packet, preventing it from entering your network. A firewall can help prevent attacks like hacking, malware infections, and other cyber threats that could compromise your data or network. Firewalls can also be configured to filter out certain types of traffic or limit access to certain resources, providing an additional layer of protection for your network. In summary, a firewall is a vital cybersecurity tool that acts as a barrier between your network and the internet, helping to keep your data and devices safe from cyber threats.

Answer Details
If the order of operation on two or more files is similar, then the operation will be sequential. Sequential operation means that the files will be processed one after the other in the same order as specified. For example, if we have two files A and B, and we want to perform the operations 'read', 'process', and 'write' on them in the order A->B, then the program will first read file A, process it, write the result, then move on to file B, read it, process it, and write the result. On the other hand, if the order of operation is not similar, the operation may be more complex or combinational. In that case, the files may be processed in a different order or simultaneously, which may require more complex programming logic. Therefore, having a similar order of operation on multiple files simplifies the programming and makes it more straightforward.

Question 21 Report
Which program translates programs to a simpler language that the computer can execute.
Answer Details
The program that translates programs to a simpler language that the computer can execute is called a compiler. A compiler is a program that takes the source code of a program written in a high-level programming language and translates it into machine code or executable code that the computer can understand and execute. The process of compiling involves several steps, including lexical analysis, syntax analysis, semantic analysis, code optimization, and code generation. When a programmer writes a program in a high-level programming language such as Java or Python, the code is not directly executable by the computer. Instead, the code must be translated into machine code, which is a low-level language that the computer can understand and execute. This is where the compiler comes in. The compiler takes the source code written in the high-level programming language and converts it into machine code that can be executed by the computer. The advantage of using a compiler is that the resulting executable code is usually faster and more efficient than code interpreted by an interpreter, which we will discuss next. Additionally, since the code is already translated into machine code, it can be executed multiple times without the need for further translation, making it faster to execute. Overall, a compiler is a program that translates high-level programming code into machine code that a computer can execute, allowing programmers to write code in a more human-readable language and then have it translated into a language that the computer can understand and execute.

Question 36 Report
A 2-input gate that can be used to pass a digital waveform unchanged at certain times and inverted at other times is ___________
Answer Details
The 2-input gate that can be used to pass a digital waveform unchanged at certain times and inverted at other times is the XOR (exclusive OR) gate. An XOR gate has two input signals and one output signal. The output is HIGH (1) if the two input signals are different, and LOW (0) if the two input signals are the same. In other words, an XOR gate produces an output signal that is the "exclusive or" of its two input signals. When one of the input signals is held at a constant logic level (either HIGH or LOW), the XOR gate can be used to pass the other input signal unchanged or inverted, depending on the value of the constant signal. If the constant signal is HIGH, the output signal will be inverted; if the constant signal is LOW, the output signal will be unchanged. This property of the XOR gate makes it useful in digital electronics for a variety of applications, such as data encryption, error detection and correction, and clock synchronization.
Question 37 Report

Answer Details
The domain name of a website is also its IP address. Every device that connects to the internet, including websites, is assigned a unique Internet Protocol (IP) address, which is a numerical label. However, remembering a long string of numbers is difficult, so domain names were created to serve as more memorable and recognizable names for websites. When you type a domain name into your web browser's address bar, your browser sends a request to a Domain Name System (DNS) server, which translates the domain name into its corresponding IP address. The IP address is then used to locate the website's server on the internet and retrieve the website's content, which is then displayed in your browser. So, while the domain name is what we typically use to identify a website, it ultimately maps to its underlying IP address, which is used to connect to the website's server and retrieve its content.
Question 38 Report
