Question 4 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 5 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 14 Report
When an input signal 1 is applied to a NOT gate, the output is ..................
Answer Details
When an input signal of 1 is applied to a NOT gate, the output will be 0. A NOT gate, also known as an inverter, is a digital logic gate that has one input and one output. The output of a NOT gate is the opposite of the input; if the input is high (1), the output will be low (0), and if the input is low (0), the output will be high (1). In other words, the NOT gate "inverts" the input signal. So, when a 1 is input to a NOT gate, the gate will invert it to 0 and produce that as the output signal. Similarly, when a 0 is input to a NOT gate, the gate will invert it to 1 and output that as the result.
Question 15 Report
The java interpreter translates a java program from ____________ to machine language.
Answer Details
The Java interpreter translates a Java program from its original form, which is a high-level programming language, into a special type of code called "bytecode." Bytecode is a low-level code that is specific to the Java Virtual Machine (JVM), which is a software layer that sits between the Java program and the computer's hardware. When a Java program is compiled, it is translated into bytecode rather than machine language. Bytecode is a form of binary code that is designed to be portable across different platforms, meaning that it can run on any computer that has a JVM installed, regardless of the specific hardware or operating system. So, to summarize, the Java interpreter translates a Java program from a high-level programming language into bytecode, which is a low-level binary code that is specific to the JVM. The bytecode can then be executed by the JVM on any computer that has it installed.

Question 19 Report
What type of errors occurs when the program is asked to implement an impossible task such as dividing a number by zero?
Answer Details
Dividing a number by zero is an impossible mathematical operation, which leads to a type of error called an "Arithmetic error". When a program encounters such an operation, it is unable to perform the calculation, and it generates an error message to indicate the issue. Arithmetic errors are a type of runtime error because they occur during the execution of the program, rather than during the compilation or writing of the code (syntax errors). Logical errors are different from arithmetic errors because they occur when the program's logic is flawed, leading to incorrect results. So, in summary, dividing by zero results in an arithmetic error because it is a mathematical impossibility that cannot be computed.

Question 27 Report
Storage which retains data after power cut off is called.
Answer Details
The type of storage that retains data even when the power is turned off is called non-volatile storage. Non-volatile storage is different from volatile storage, which loses all data when the power is turned off. To help you understand the difference, imagine that you have two types of memory: a whiteboard and a notebook. The whiteboard is like volatile memory because anything you write on it will disappear as soon as you erase it or turn off the lights. On the other hand, the notebook is like non-volatile memory because anything you write in it will remain there until you deliberately erase or destroy it. Similarly, non-volatile storage, such as hard drives, solid-state drives (SSDs), and flash drives, can retain data even when the power is turned off. This is because the data is stored using physical means that do not require an electrical charge to be maintained. In contrast, volatile storage, such as RAM, loses all data when the power is turned off because the data is stored using electrical charges that require a constant supply of power to be maintained. Overall, non-volatile storage is essential for long-term data storage because it can retain data even in the absence of power, whereas volatile storage is useful for short-term storage of data that does not need to be preserved beyond the current session or power cycle.
Question 28 Report
In the files, if order of operation on two or more files are similar, then operation will be
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 29 Report
________ is the process of dividing the disk into tracks and sectors

Question 40 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.
