The correct answer is to check that all cables are correctly attached and the power source is switched on. This is because if the computer is not turning on, it is likely due to a power issue. By checking that all cables are properly connected and ensuring that the power source is switched on, you can troubleshoot and potentially resolve the problem. This step is important before seeking technical support or trying other methods.

The given answer, 1 024 GB, is correct because a terabyte (TB) is equal to 1 024 gigabytes (GB). The prefix "tera-" in the metric system denotes a factor of 10^12, which means that one terabyte is equal to 1 024 multiplied by 1 024 megabytes, resulting in 1 048 576 megabytes. Since there are 1 024 megabytes in a gigabyte, one terabyte is equal to 1 024 gigabytes.

The options provided in the question are all types of computer network configurations, except for "Book." A star network configuration connects all devices to a central hub, a bus network configuration connects devices in a linear manner using a common communication line, and a ring network configuration connects devices in a circular loop. However, "Book" does not represent any recognized computer network configuration, making it the correct answer.

An external hard drive is a data storage device that can store approximately 1 TB of data and allows you to take it to another location. Unlike a USB or CD-RW, an external hard drive offers a larger storage capacity, making it suitable for storing a significant amount of data. Additionally, it is portable and can be easily disconnected from one computer and connected to another, providing convenience and flexibility for transferring data between different locations. A floppy disk, on the other hand, has a much smaller storage capacity and is not commonly used anymore due to its limited capabilities.

Random Access Memory (RAM) is a type of computer memory that allows data to be stored and retrieved in any order, regardless of the physical location of the data. It is called "random access" because the computer can access any memory cell directly, without having to go through the cells in sequence. This makes RAM much faster than other types of memory. Therefore, the correct answer is Random Access Memory.

The higher the number of RAM a computer has, the more software applications it can have active at the same time. RAM (Random Access Memory) is a type of computer memory that is used to store data that is actively being used by the computer. When a computer runs multiple software applications simultaneously, it requires more RAM to store the data and instructions for each application. Therefore, having a higher amount of RAM allows the computer to handle a larger number of active software applications efficiently.

Modems are not considered to be consumables because they are not typically used up or depleted during normal computer usage. Consumables are items that are regularly replaced or replenished, such as CD-Rs, floppy disks, and cartridges, which can be used only a limited number of times before they need to be replaced. Modems, on the other hand, are hardware devices that facilitate internet connectivity and do not require regular replacement or replenishment.

BIOS stands for Basic Input/Output System. It is a firmware that is built into a computer's motherboard. BIOS is responsible for initializing and testing hardware components during the boot-up process. It also provides a bridge between the operating system and the hardware, allowing the operating system to communicate with the hardware devices.

VGA input is not an item of external computer hardware because it is a type of video input port that allows the computer to connect to an external display device, such as a monitor or projector. It is not a physical device itself, but rather a port that is used to connect other external hardware. Keyboard, printer, and USB are all physical devices that can be connected to a computer externally.

Correct lighting is a workplace health and safety standard that should be followed when operating computer hardware. Adequate lighting is important to prevent eye strain and fatigue, which can result in decreased productivity and increased risk of accidents. Proper lighting can also help reduce glare on computer screens, minimizing the risk of vision problems. Therefore, ensuring that the workspace is well-lit is essential for maintaining a safe and healthy working environment when using computer hardware.

The correct answer is "Start the computer by pressing the power button." This is because a cold start refers to starting the computer from a completely powered off state, which requires pressing the power button to initiate the booting process. Restarting the computer, starting it from hibernation status, or starting it from sleep status do not involve a cold start as the computer is already in a powered on or semi-powered state.

The correct answer is RAM of the computer. When using Microsoft Word, the open/edited document that you are viewing on your screen is held in the RAM (Random Access Memory) of the computer. RAM is a type of computer memory that allows data to be stored and accessed quickly by the computer's processor. It is a temporary storage location where the computer can read and write data while it is being used. The document is not permanently saved until you choose to save it to a storage device such as a USB or the computer's hard drive.

The correct answer is "Interconnected Networks." The Internet is a global network of interconnected computer networks that allows communication and sharing of information between various devices and systems worldwide. It is not an abbreviation for "Installed Networks" or "Individual Networks."

The correct answer is "Data entered, processed, stored, printed." This sequence accurately describes the flow of computer processing stages. First, data is entered into the computer system. Then, the entered data is processed, which involves performing calculations, executing instructions, or manipulating the data in some way. After processing, the data is stored in memory or on a storage device for future use. Finally, the stored data can be printed or displayed as output for the user to view.

The correct answer is Printers, Speakers and Microphone. These items are all examples of peripherals. Peripherals are devices that are connected to a computer system to enhance its functionality or provide additional features. Printers are used to produce physical copies of documents, speakers are used for audio output, and microphones are used for audio input.

Cloud storage is considered to be software because it refers to the online storage services that allow users to store and access data over the internet. It involves the use of software applications and platforms that enable data to be stored and retrieved from remote servers rather than local hardware devices. Cloud storage software provides a virtual storage environment where users can store, manage, and access their data from anywhere with an internet connection. Therefore, it is categorized as software rather than hardware or peripheral devices.

Firewalls are not typically considered to be virus protection devices. Firewalls are hardware or software systems that monitor and control network traffic based on predetermined security rules. They act as a barrier between a trusted internal network and an untrusted external network, filtering out unauthorized access and potential threats. While firewalls can provide some level of protection against viruses by blocking malicious traffic, their primary function is to control network traffic, not to detect or remove viruses. Therefore, the correct answer is either hardware or software, as firewalls can be implemented using either.

You would not need to check to see if the monitor is switched on because the issue is with the keyboard, not the monitor. The monitor being switched on or off does not affect the functionality of the keyboard.

The correct statement is "Ensure that the computer operator can be seated ergonomically." This statement is correct because it emphasizes the importance of providing a comfortable and safe working environment for the computer operator. Ergonomics is the practice of designing and arranging equipment and furniture in a way that promotes efficiency, comfort, and reduces the risk of injury. Ensuring that the computer operator can be seated ergonomically helps prevent musculoskeletal disorders and promotes productivity.

An integrated package is cheaper than a software suite because it does not have separate components that can be installed and used individually. Unlike a software suite, which includes a range of software with advanced features, an integrated package typically does not include spreadsheets and email. This means that users do not have to pay for additional components or features that they may not need or use, resulting in a lower cost overall.
