Therefore, Microsoft Word is categorized as a word processing application.

An application program relies on an operating system to provide essential services and resources for its execution. The operating system manages hardware resources, provides a user interface, and ensures the smooth execution of programs. Without an operating system, an application program would not have access to necessary system resources and would not be able to function properly. Therefore, it is true that an application program needs an operating system to function.

The computer system suddenly changing its screen saver and not responding to user commands suggests a potential issue with the software. Since the user recently went online and downloaded some software, the first thing she should check is whether she accidentally downloaded a computer virus. Viruses can cause various issues with computer systems, including changing settings and rendering the system unresponsive. Therefore, it is important to investigate this possibility before considering other factors such as power failure, processor removal, or room temperature.

Bill Gates and Paul Allen founded Microsoft together. They started the company in 1975 and played crucial roles in its early development. Bill Gates served as the CEO and Paul Allen as the executive vice president. They worked together to create and market software products, most notably the MS-DOS operating system, which became the foundation for Microsoft's success. Their partnership and innovative ideas laid the groundwork for Microsoft's growth into one of the world's largest and most influential technology companies.

Charles Babbage is the correct answer because he was the one who theorized the Difference Engine and also built the Analytical Engine. Babbage was a British mathematician and inventor who is often considered the "father of the computer." He designed the Difference Engine, which was a mechanical calculator capable of performing mathematical calculations. Although the Difference Engine was never fully built during Babbage's lifetime, his ideas and designs laid the foundation for modern computers. Babbage also designed the Analytical Engine, which was a more advanced machine capable of general-purpose computation and is considered a precursor to modern computers.

The correct answer is Central Processing Unit. The CPU is the primary component of a computer that performs most of the processing inside the computer. It carries out instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations. It is often referred to as the "brain" of the computer, as it executes instructions and coordinates the activities of all the other hardware components.

The motherboard is recognized as the main circuit board in a computer. It is responsible for connecting and providing power to all the other components of the computer, such as the CPU, graphics card, sound card, and power supply unit. It acts as a central hub, allowing all the components to communicate with each other and work together to perform various tasks. Without a motherboard, the computer would not be able to function properly.

A CPU (Central Processing Unit) is the main component of a computer that performs most of the processing inside the computer. It is responsible for executing instructions and performing calculations. The motherboard is the main circuit board of a computer, which houses various components including the CPU. Therefore, the CPU is most likely to be found on a motherboard.

The correct answer is .doc because Microsoft Word documents typically have a file extension of .doc. This extension is used to identify and open Word documents in the Microsoft Word application.

On June 29th of 2007, Apple released the iPhone. This revolutionary device marked a significant milestone in the history of smartphones, combining a mobile phone, an iPod, and an internet communication device into one compact device. The iPhone introduced a touch screen interface, a sleek design, and various innovative features that revolutionized the way people interacted with their mobile devices.

A network in computer terms refers to a group of computers working together. This means that multiple computers are connected and able to share resources, communicate, and collaborate with each other. This allows for the sharing of data, files, and devices such as printers. Networks can be local, such as a home or office network, or they can be global, such as the internet.

The correct answer is "All the physical components of the computer." Computer hardware refers to all the tangible and physical parts of a computer system, such as the motherboard, CPU, memory, hard drive, graphics card, etc. It does not include peripherals like printers or input devices, but rather focuses on the internal components that make up the computer system.

Steve Jobs and Steve Wozniak founded Apple Computers. They started the company in 1976 and played key roles in developing and marketing the first Apple computers, such as the Apple I and Apple II. Jobs was responsible for the business side of the company, while Wozniak focused on the technical aspects. Their collaboration and innovative ideas laid the foundation for the success of Apple Computers, which eventually became one of the most valuable and influential technology companies in the world.

A notebook computer is a better choice for portability compared to a desktop computer or a mainframe. Unlike a desktop computer, which is bulky and requires a dedicated workspace, a notebook computer is compact and lightweight, allowing users to easily carry it around. Additionally, a mainframe is a large and powerful computer system designed for handling complex tasks and serving multiple users simultaneously, but it is not designed for portability. Therefore, a notebook computer is the most suitable option when considering portability.

An operating system is the correct answer because it is the software that manages computer hardware and software resources and provides common services for computer programs. It supports the user's interaction with the computer by handling tasks such as memory management, file management, and device management. The operating system acts as an intermediary between the user and the computer hardware, allowing the user to effectively utilize the computer's resources and run applications.

A firewall is a security measure used to protect computer systems from unauthorized access and potential threats. It acts as a barrier between a trusted internal network and an external network, such as the internet, by monitoring and controlling incoming and outgoing network traffic. It helps prevent malicious attacks, such as hacking attempts, viruses, and malware, by filtering and blocking unauthorized connections and suspicious activities. By doing so, a firewall helps maintain the integrity and confidentiality of computer systems and the data they contain.

Encryption is the correct answer because it is the process of changing the format of information in such a way that it becomes unreadable and can only be accessed by authorized individuals who possess the key to decrypt it. Encryption is commonly used to protect sensitive data and ensure its privacy and security during storage or transmission.

Topology is the correct answer because it refers to the arrangement or configuration of the various components of a computer network. It describes the physical or logical layout of the network, including the connections between devices and the way data flows within the network. The term "lay-out" is not commonly used in the context of computer networks, "format" is more related to the structure or organization of data, "topography" refers to the physical features of a landscape, and "map" is a visual representation of a network but does not specifically describe how it is laid out.
