What does a linker program do?
Answer Details
A linker program is a software tool that links different parts of a computer program together. Think of a computer program as a puzzle with many pieces. The linker takes all those pieces and puts them together to make the complete program. The linker performs tasks such as combining object files, resolving symbol references, and creating the final executable file. The linker program takes care of the following tasks: 1. Linking the program with other programs needed for its execution. For example, if a program uses a library like the C standard library, the linker will link the program with that library so that the program can use its functions. 2. Relocating the program to execute from a specific memory area allocated to it. This means that the linker will place the program in a specific area of the computer's memory so that it can be executed. 3. Interfacing the program with the entities generating its input data. This means that the linker will make sure that the program can receive data from other parts of the system, such as user input or data from a file. In summary, the linker program is responsible for putting all the pieces of a computer program together so that it can be executed correctly.

Question 13 Report
The Domain name of a website is also its__________
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 18 Report
The first commuters were programed using _________
Answer Details
The first commuters were programmed using machine language. Machine language is the lowest-level programming language that can be used to write computer programs. It consists of binary code, which is a sequence of 1's and 0's that the computer can understand and execute directly. The first computers, such as the ENIAC, did not have high-level programming languages like we have today, such as Python or Java. Instead, they had to be programmed using machine language. This meant that the programmers had to manually enter long sequences of binary code to perform even the simplest tasks on the computer. As computers advanced, higher-level programming languages were developed to make programming easier and more accessible to non-experts. These higher-level languages are often compiled into machine language, which the computer can then execute. But in the early days of computing, programmers had no choice but to write code directly in machine language.
Question 19 Report
How many different values can a bit have?
Answer Details
A bit is the smallest unit of digital information in computing, and it can have two possible values: 0 or 1. This is because a bit is used to represent a binary digit, which can be either on or off, true or false, or high or low. So, the answer is 2. To give an example, imagine a light switch that can either be turned on or off. We can use a bit to represent the state of the switch, where 0 represents the switch being off, and 1 represents the switch being on. In this case, a single bit is enough to represent the two possible states of the switch. Similarly, in computing, a single bit is enough to represent two possible states of any digital information.

Question 21 Report
_______ is the process of finding errors and fixing them within a program.
Answer Details
The process of finding errors and fixing them within a program is called debugging. When a program is being developed, it may contain errors, also known as bugs, that prevent it from functioning properly. Debugging is the process of identifying and fixing these errors. Debugging can involve a number of techniques, such as analyzing error messages, reviewing code, and stepping through the program line by line to find where errors occur. Once an error is identified, the programmer can make changes to the code to correct the issue. Compiling is the process of translating source code into machine code, which can then be executed. Execution is the process of running a program. Scanning, in the context of programming, typically refers to the process of analyzing code for security vulnerabilities rather than identifying and fixing errors. In summary, debugging is the process of identifying and fixing errors in a program, whereas compiling, executing, and scanning are different processes that serve different purposes in the development and operation of a program.

Question 27 Report
___________ booting is done by turning on the computer at first instance.
Answer Details
"Cold" booting is done by turning on the computer at first instance. Booting is the process of starting a computer, and it can be done in two ways: cold booting and warm booting. A cold boot occurs when a computer is turned on after being completely shut down. This is the first time the computer is starting up and all components are starting from a completely powered-off state. This type of booting is often necessary when there are problems with the operating system or software and a restart does not resolve the issue. A warm boot, on the other hand, occurs when a computer is restarted without first being shut down. This type of booting is usually faster than a cold boot because some components remain powered on and do not need to be restarted from a completely powered-off state. The options "hot," "spicy," and "cool" are not relevant to booting a computer.
Question 28 Report
What is considered the brain of the computer?
Answer Details
