New technology devices are often referred to as gadgets because the term "gadget" typically refers to small, innovative, and often electronic devices that are designed to perform specific functions or tasks. These devices are usually portable and user-friendly, making them popular among consumers. The term "goods" is too broad and does not specifically refer to technology devices. "Tweaks" suggests small modifications or adjustments, which does not accurately describe new technology devices. Therefore, "gadgets" is the most appropriate term to describe new technology devices.

The correct answer is "bugs". The word "bugs" is often used to refer to glitches or errors in computer programs. Therefore, the statement "I didn't like this new computer program is full of bugs" implies that the program has a lot of issues or malfunctions, which is why the person did not like it.

The term "software" refers to programs that are installed on a computer. This includes applications such as games and Ms Office, as well as other programs that perform various tasks on the computer. Hardware, on the other hand, refers to the physical components of the computer system. Therefore, the correct answer is software as it accurately describes the programs installed on a computer.

A processor, or CPU, is responsible for interpreting and executing commands from the computer's hardware or software. It performs calculations, manages data flow, and controls the overall operation of the computer. This makes it the central component that drives the computer's functionality, earning it the metaphorical title of the "brain" of the computer. Therefore, the statement that a CPU is considered to be the "brain" of the computer is true.

The statement "The first computers were built to perform calculations" is true. The earliest computers, such as the ENIAC, were specifically designed to perform complex mathematical calculations. These machines were developed during the mid-20th century and were primarily used for scientific and military purposes. They were massive in size and relied on vacuum tubes and punched cards for processing and input/output operations. Over time, computers evolved to handle various tasks beyond calculations, such as data storage, communication, and multimedia processing. However, their initial purpose was indeed to perform calculations.

A router is a device that is connected to a modem and receives the Internet signal from it. It then spreads the signal to several computers either through a serial cable or through Wi-Fi. A router acts as a central hub that allows multiple devices to connect to the Internet and communicate with each other within a local network.

The iMac and MacBook are not products of Microsoft, IBM, or Google. These two products are actually developed and manufactured by Apple Inc. Therefore, the correct answer is "None of the above".

Personal computers started to become popular in people's households from the 1980s. This was mainly due to the introduction of affordable and user-friendly computers like the Apple II and IBM PC. These computers offered individuals the opportunity to have a computer at home for personal use, leading to a rise in computer ownership among households during that time. As technology advanced and prices continued to drop, personal computers became even more prevalent in households worldwide.

MS Windows is not an example of computer hardware because it is an operating system software that runs on computer hardware. The other options listed - keyboard, printer, and monitor - are all examples of computer hardware as they are physical components that can be connected to a computer.

The given statement is true. IBM built one of the first modern computers called the Mark 1 in 1944. This computer was a massive machine that operated continuously for 15 years.

Many new mobile devices use a touch interface instead of a real keypad. This means that instead of physical buttons, the user interacts with the device by touching the screen. A touch interface allows for a more intuitive and user-friendly experience, as it is easier to navigate and interact with the device using gestures and taps on the screen. It also allows for more flexibility, as the interface can adapt and change based on the specific needs and preferences of the user.

To prevent your computer from being infected by viruses, it is important to take multiple precautions. Making frequent backups ensures that even if your computer gets infected, you can still retrieve your important data. Installing a virus scanner helps in detecting and removing viruses from your system. Avoiding the download of questionable files reduces the risk of downloading files that may contain viruses. Therefore, all of the above options are necessary to effectively prevent virus infections on your computer.

A computer virus is a malicious software program that is designed by programmers to copy itself and attach itself to other files. This means that all of the given options are correct as they accurately describe the characteristics and behavior of a computer virus.

A hard drive is a type of storage drive that is commonly used to store files on a computer. It is the primary storage device for all software on a PC. Hard drives are non-volatile, meaning they retain data even when the computer is turned off. They provide a large amount of storage space and are typically installed inside the computer's casing.

The correct answer is Central Processing Unit (CPU). The CPU is responsible for interpreting and executing commands from the computer's hardware or software. It is considered the brain of the computer, as it performs all the necessary calculations and operations to run programs and perform tasks. The CPU interacts with other components of the computer, such as the motherboard and sound card, but it is specifically responsible for processing instructions and data.

The term "broadband" refers to high-speed internet access, and in the context of the question, it specifically refers to high-speed internet in mobile locations. This means that users can access the internet at fast speeds using their mobile devices, allowing them to browse websites, stream videos, and download files quickly and efficiently. "Interface" and "4G" are not relevant in this context as they do not specifically refer to high-speed internet in mobile locations.

Tim Berners-Lee is credited with inventing the Internet. In 1989, he proposed the concept of the World Wide Web, which allowed information to be shared and accessed over the Internet. Berners-Lee developed the necessary technologies, such as HTML, HTTP, and URLs, that are still used today. His invention revolutionized communication and information sharing on a global scale, making the Internet accessible to the general public.

Bill Gates became famous for creating a popular operating system. He co-founded Microsoft and played a key role in the development of the operating system known as MS-DOS, which became widely used and established Microsoft as a major player in the technology industry. Gates' contributions to the field of operating systems have had a significant impact on the way computers are used today.

A sound card is a part of a computer that sends audio/sound information to speakers or headphones. It is responsible for processing and converting digital audio signals into analog signals that can be played through speakers or headphones. Without a sound card, computer users would not be able to listen to audio files as the computer would not be able to produce sound output.

A video card is a piece of hardware that processes and sends graphical information to the screen. It is essential for generating images, especially in computer games where a large number of images need to be rendered. The quality of the images depends on the quality of the video card. A sound card, on the other hand, is responsible for processing and producing audio, not graphical information. Picture card and disk card are not commonly used terms in relation to computer hardware.

Charles Babbage is not credited with inventing the first computer known as the difference machine in 1822. While Babbage did design and conceptualize the difference machine, it was never fully constructed during his lifetime. The first fully functional computer, known as the Analytical Engine, was also designed by Babbage but was never built. Therefore, the statement that the difference machine became very popular in many people's households is false.

Henry Edward Roberts is known as the "Father of the PC" because he was the inventor of the Altair 8800, the world's first personal computer. The Altair 8800 was a groundbreaking device that sparked the personal computer revolution and paved the way for the development of modern PCs. Roberts' creation laid the foundation for the future of computing and revolutionized the way people interact with technology.
