Information is created when data is processed, organized, and given meaning. For example, taking the average of the numbers in the list would turn the data into meaningful information.
Question 8 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 9 Report
In any software package, which of the following versions represents a major improvement on the previous version?
Answer Details
In any software package, a new version number that increases the whole number before the decimal point represents a major improvement on the previous version. Therefore, the versions that represent a major improvement on the previous version is 2.0.
In software development, version numbers are used to identify different releases or iterations of a program. A new version number is typically assigned when significant changes or improvements are made to the software. The first number before the decimal point in a version number is known as the major version number. When this number increases, it indicates that there has been a significant change or improvement in the software that warrants a new release.
The second number after the decimal point is the minor version number, which typically represents smaller changes or bug fixes. Therefore, 2.0 is a major releases that represent significant improvements over the previous version, while 1.0, 1.5 and 2.5 are minor releases that represent smaller changes or bug fixes.
In summary, a new software version number that increases the major version number before the decimal point represents a major improvement on the previous version, indicating that significant changes or improvements have been made to the software.
Question 10 Report

Answer Details
The tier in which the database resides along with the query processing language is called the data tier. In software architecture, the data tier is one of the three layers of a typical multi-tier architecture, with the other two being the presentation tier (dealing with the user interface) and the application tier (containing the business logic). The data tier is responsible for managing the storage and retrieval of data, as well as the processing of queries that operate on that data. The data tier typically consists of one or more database management systems (DBMS), which are specialized software systems designed to manage large amounts of structured data. The DBMS provides a structured way to store data and a language for querying and manipulating that data, such as SQL (Structured Query Language). In summary, the data tier is the layer in a multi-tier software architecture where the database resides, and where queries are processed using a specialized query language like SQL. It is responsible for managing the storage and retrieval of data in an efficient and secure manner.
Question 11 Report
For what does WAN stand?
Answer Details
WAN stands for Wide Area Network. A network is a collection of devices (like computers, printers, and servers) that are connected together to communicate and share resources. A WAN is a type of network that covers a large geographic area, such as a city, a country, or even the whole world. Unlike a Local Area Network (LAN), which is limited to a small area like a home or office building, a WAN connects devices over a larger distance using a variety of technologies such as telephone lines, fiber optic cables, and satellite links. WANs are used by organizations to connect their different offices and branches in different locations, and to provide access to the internet or cloud-based services. For example, a company with offices in New York and London might use a WAN to connect the two locations and allow employees to share data and resources.
Question 12 Report
What is the full form of TCP?
Answer Details
The full form of TCP is Transmission Control Protocol. TCP is a communication protocol that is used to send and receive data over the internet. It is one of the main protocols in the Internet Protocol Suite (commonly referred to as TCP/IP), which is the set of rules and standards that govern how data is transmitted on the internet. TCP provides a reliable, ordered, and error-checked delivery of data between applications running on different devices. It breaks down the data into small packets, and each packet is numbered and tracked to ensure that it arrives at its destination in the correct order and without errors. If a packet is lost or damaged during transmission, TCP detects the error and retransmits the missing or damaged packet. TCP is widely used for sending and receiving data between web servers and web browsers, and for many other applications that require reliable and error-free data transmission over the internet.

Question 14 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 15 Report
________ is the process of dividing the disk into tracks and sectors
Answer Details
The process of dividing a disk into tracks and sectors is called "formatting". Formatting prepares a new disk for use by creating a file system that can store and organize data. Tracks are circular paths on the disk, and sectors are small sections within each track. By dividing the disk into tracks and sectors, formatting allows the operating system to efficiently read and write data to the disk. Think of it like drawing lines on a blank piece of paper to create a grid. The grid allows you to organize your content and write in an orderly manner. Similarly, formatting divides the disk into a grid-like structure that the computer can use to organize and store data.

Question 17 Report
Which of the memories must be refreshed many times per second?
Answer Details
Out of the given options, Dynamic RAM (DRAM) must be refreshed many times per second. DRAM is a type of computer memory that stores data in a capacitor within each memory cell. The capacitor can hold a charge, representing either a 0 or 1, but it gradually leaks over time, meaning that the data will eventually fade away. To prevent this data loss, the memory controller sends a refresh command to the DRAM chip many times per second. This refresh command recharges the capacitors in the memory cells to maintain the data stored in them. In contrast, Static RAM (SRAM) does not require refreshing, as it uses a different type of storage element that does not leak charge like a capacitor. EPROM and ROM are non-volatile memory types, meaning that they retain data even without power, and do not require refreshing.
Question 18 Report
What is the shortcut key to "undo" last action on a Microsoft word page?
Answer Details
The shortcut key to "undo" the last action on a Microsoft Word page is "Ctrl + Z". When you perform an action on a Word page, such as typing, deleting, formatting or copying text, you can undo that action by using the "Ctrl + Z" keyboard shortcut. This will revert the page to the state it was in before the action was performed. For example, if you accidentally delete a sentence, you can press "Ctrl + Z" to undo the deletion and restore the sentence. The "Ctrl + Z" shortcut is a very useful and commonly used feature in Microsoft Word as it allows you to quickly correct mistakes without having to manually undo each action. It can be used multiple times to undo several actions in a row. If you want to redo an action that was previously undone, you can use the "Ctrl + Y" keyboard shortcut. In summary, the "Ctrl + Z" keyboard shortcut is used to undo the last action performed on a Microsoft Word page, allowing you to easily correct mistakes and restore the previous state of the page.

Question 30 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.

___________ 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 39 Report
Which of these is not a job of the operating system
Answer Details
The job of the operating system that is not listed among the options is "Handling HTTP requests for Web pages." The operating system is the most important software that runs on a computer, providing an interface between the user and the computer hardware. It performs various functions to ensure that the computer system operates smoothly and efficiently. One of the key jobs of the operating system is to manage the computer's resources, such as allocating memory to programs that are running on the computer. The operating system is responsible for managing the computer's memory, ensuring that each program has enough memory to run efficiently, and preventing one program from using another program's memory. Another important job of the operating system is to provide security by preventing unauthorised access to files and data on the computer. It controls access to the computer's resources and ensures that only authorised users have access to the files and data that belong to them. However, handling HTTP requests for web pages is not a job of the operating system. Instead, this task is handled by web servers that run on top of the operating system. Web servers receive requests from clients, such as web browsers, and serve web pages to them over the internet. In summary, while the operating system performs many important tasks, such as managing resources and providing security, handling HTTP requests for web pages is not one of its jobs.
