The correct answer for this question is 'Vint Cerf' because he is one of the key contributors to the development of TCP/IP protocol. Vint Cerf, along with Robert Kahn, is widely recognized as the co-inventor of TCP/IP, which is the foundational protocol of the internet.
The correct answer is '4' because HTML has a total of 6 heading elements, numbered from h1 to h6. However, the question is asking specifically for the number of headings, which excludes the h1 and h2 elements. Therefore, the correct answer is '4'.
The correct answer is 'A. An electronic automated machine that can solve problems involving words and numbers' because it accurately describes the main function and capabilities of a modern digital computer. Digital computers are designed to process both numerical and textual information, making them versatile problem-solving tools. This definition captures the essence of what a modern digital computer is and how it operates.
The correct answer is 'A. Digital' because computers operate using digital technology, which processes data in binary code (0s and 1s). This distinguishes them from analog devices, which process data in continuous wave forms. Therefore, in today's world, most computers are digital in nature.
The correct answer is 'A. Memory or disk space' because a worm virus continues to replicate and spread throughout a system until it consumes all available memory or disk space. Once the system runs out of memory or disk space, the worm virus is unable to continue replicating and spreading, effectively terminating its activity. This makes memory or disk space the limiting factor that ultimately stops the worm virus from causing further damage.
The correct answer is 'A. RAM' because Random Access Memory (RAM) serves as a temporary storage location for data that the CPU needs to access quickly. It acts as a buffer between the CPU and the main memory by holding frequently accessed data and instructions, allowing for faster processing speeds. This makes RAM an essential component in optimizing the performance of a computer system.
The correct answer for this question is 'Single line spacing' because in Microsoft Word, pressing Ctrl1 is a shortcut for applying single line spacing to the selected text. This command helps to quickly adjust the spacing between lines in a document without having to navigate through the menu options.
The correct answer for this question is 'Vint Cerf' because he is widely recognized as one of the founding fathers of the internet and played a crucial role in the development of TCP/IP protocols, which are the foundation of modern computer networking. His contributions have had a lasting impact on the field of networking, earning him the title of the father of computer networking.
The correct answer is '4 bits' because a nibble is a unit of digital information that consists of 4 bits. This means that there are 16 possible combinations (2^4) that can be represented by a nibble.
The correct answer is 'A. Arithmetic Logic Unit' because the ALU is a fundamental component of a computer's central processing unit (CPU) responsible for performing arithmetic and logical operations on data. It is the part of the CPU that carries out calculations and makes decisions based on those calculations, making it a crucial component for the overall functioning of the computer.
