A virus is a program that can cause harm to computer operations. Unlike Fortran and C-language, which are programming languages used to write computer programs, a virus is specifically designed to disrupt or damage the normal functioning of a computer system. Viruses can infect files, spread across networks, and perform malicious activities, such as deleting files, corrupting data, or stealing sensitive information. Therefore, a virus is the correct answer as it poses a direct threat to computer operations.

The number 100101 is an example of a binary number because it consists of only two digits, 0 and 1, which are the building blocks of the binary numeral system. In binary, each digit represents a power of 2, and the number is calculated by adding up the values of the digits.

Charles Babbage is considered the father of modern computer because of his significant contributions to the development of early computers. He designed the Analytical Engine, which is considered the first general-purpose computer concept. Babbage's ideas and designs laid the foundation for the modern computer, including concepts such as input, output, storage, and processing. Although he was unable to complete the construction of the Analytical Engine during his lifetime, his work greatly influenced future generations and paved the way for the computers we use today.

RAM stands for Random Access Memory. It is a type of computer memory that allows data to be read from or written to in any order, regardless of the physical location of the data. This means that the computer can access any piece of data stored in RAM directly, without having to search through the entire memory. RAM is a volatile memory, which means that its contents are lost when the computer is turned off or restarted. It is used by the computer's operating system and applications to store data that is being actively used, providing fast and temporary storage for the computer's processes.

Computers use the binary language for processing data. Binary is a base-2 number system that uses only two digits, 0 and 1, to represent information. In computers, data is stored and processed in binary format, which is represented using electrical signals or digital codes. This binary language allows computers to perform calculations, execute instructions, and store and retrieve data efficiently.

The correct answer is "hypertext transfer protocol". HTTP stands for Hypertext Transfer Protocol, which is the underlying protocol used for transferring data over the internet. It is the foundation of any data exchange on the Web and allows for the retrieval of resources such as HTML documents, images, videos, etc. It defines how messages are formatted and transmitted, as well as how servers and clients should respond to various commands.

A byte consists of 8 bits. In computing, a bit is the basic unit of information and can have a value of either 0 or 1. A byte is a unit of storage that can represent a single character of text or a small amount of numerical data. It is composed of 8 bits, allowing for a total of 256 different possible combinations of 0s and 1s. Therefore, the correct answer is 8.

A supercomputer is the fastest type of computer that can perform complex operations at very high speed. It is designed to handle large-scale calculations and simulations, making it ideal for scientific research, weather forecasting, and other computationally intensive tasks. Supercomputers typically have multiple processors working together in parallel to achieve their high processing speeds. They are used in various fields where massive amounts of data need to be processed quickly, such as in physics, chemistry, and engineering.

The correct answer is Five. This is because computers have evolved through five distinct generations. Each generation is characterized by technological advancements and changes in hardware and software. The first generation used vacuum tubes, the second generation used transistors, the third generation used integrated circuits, the fourth generation used microprocessors, and the fifth generation is marked by the development of artificial intelligence and advanced computing technologies.

The correct answer is "five". The question is asking about the generation of modern digital computers. The five generations of computers are based on the advancements in technology and hardware. The first generation used vacuum tubes, the second used transistors, the third used integrated circuits, the fourth used microprocessors, and the fifth generation is characterized by the use of artificial intelligence and parallel processing. Therefore, modern digital computers are considered to be under the fifth generation.

The correct answer is 1 million bytes. A gigabyte is a unit of digital information storage that is equal to 1,000,000 bytes. It is commonly used to measure the capacity of computer storage devices and the size of digital files.

Debugging is the process of identifying and fixing errors or bugs in a program. It involves analyzing the code, identifying the cause of the error, and making the necessary corrections to ensure the program runs correctly. Debugging is an essential step in software development as it helps to ensure the program functions as intended and produces the expected output.

Primary memory is available in the form of silicon chips because silicon is the most commonly used material for manufacturing integrated circuits, including memory chips. Silicon has excellent electrical properties, making it ideal for creating transistors and other components that are essential for storing and retrieving data in primary memory. Additionally, silicon is abundant and relatively inexpensive, making it a cost-effective choice for mass production of memory chips.

The internal hard disk is the correct answer because it is a crucial component of a computer system that stores all the data, software, and operating system. It is responsible for the long-term storage of files and programs, allowing the computer to access and retrieve data quickly. Without an internal hard disk, a computer would not be able to function properly or store any data. The mouse and monitor are peripheral devices that enhance the user's interaction with the computer, but they are not as essential or widely used as the internal hard disk.

The correct answer is Ctrl+Home or Ctrl+End. These keyboard shortcuts are commonly used to quickly move the cursor to the beginning or end of a document. Ctrl+Home moves the cursor to the start of the document, while Ctrl+End moves it to the end. These shortcuts are often used in word processing programs and text editors to navigate through large documents efficiently.

ROM (Read-Only Memory) is a type of memory that retains its data even when the power supply is turned off. Non-volatile memory refers to a type of memory that retains its data even without a power supply, making it the correct answer for the question. Volatile memory, on the other hand, requires a continuous power supply to retain its data. Dynamic and static are types of RAM (Random Access Memory) and are not relevant to the question.

The period of First generation computers starts from 1940-1956. This is because the first generation of computers, also known as vacuum tube computers, were developed during this time. These computers used vacuum tubes for circuitry and magnetic drums for memory. They were large, expensive, and consumed a lot of power. Examples of first-generation computers include ENIAC and UNIVAC. The period of 1940-1956 marks the beginning and end of this era of computer development.

Moore's First Law refers to the observation made by Gordon Moore, co-founder of Intel, that the number of transistors on a microchip doubles approximately every two years, leading to a rapid improvement in computer hardware performance. This law has been a guiding principle in the technology industry, highlighting the exponential growth and advancement in computing power over time.

Gary Kildall is credited with inventing BIOS (Basic Input/Output System). BIOS is a firmware that initializes the hardware components of a computer during the booting process. Kildall developed the CP/M operating system, which was widely used in early personal computers. He also created the first BIOS, known as the CP/M BIOS, which allowed CP/M to run on different hardware platforms. His contributions to the development of BIOS laid the foundation for modern computer systems and their compatibility with various hardware configurations.

The given IP address 192.168.900.1 is not a valid IP address because each segment of an IP address should be between 0 and 255. In this case, the third segment is 900 which is outside the valid range.
