IC3 Gs3 Computer Fundamentals

The brain of the computer is the CPU (Central Processing Unit). It is responsible for executing instructions, performing calculations, and managing the flow of data within the computer system. The CPU acts as the control center and performs the majority of the processing tasks, making it the most important component in a computer. RAM (Random Access Memory) and ROM (Read-Only Memory) are types of memory used by the computer, while BIOS (Basic Input/Output System) is responsible for initializing hardware components during the boot-up process. However, none of these components function as the brain of the computer like the CPU does.

The keys across the top of the keyboard, F1-F12, are called function keys. These keys are typically programmed to perform specific functions within a software program or operating system. They are commonly used for tasks such as opening help menus, navigating through documents or web pages, adjusting screen brightness or volume, and activating special features or shortcuts.

The given options are all components of a computer system. RAM stands for Random Access Memory, which is a type of computer memory that is used to store data that is being actively used by the computer. CPU stands for Central Processing Unit, which is the main component of a computer that performs most of the processing inside the computer. Motherboard is the main circuit board of a computer, which connects and allows communication between all the other components. "Main Computer" is not a specific hardware component, but rather a term used to refer to the entire computer system. Therefore, the correct answer is Motherboard.

Function keys are the keys on a keyboard that are programmable to perform specific tasks or commands. These keys are typically labeled as F1, F2, F3, and so on, and can be customized to execute various functions depending on the software or program being used. They are commonly used for shortcuts, such as opening a help menu, saving a document, or refreshing a webpage.

A server is a computer that is specifically designed to provide resources and data to other computers or devices on a network. It acts as a central hub, allowing multiple users to access and share information stored on the server. This can include files, databases, applications, and other resources. By designating a server, organizations can efficiently manage and distribute resources, improving collaboration and productivity among users. Therefore, the statement "A server is a computer that has been designated to share resources and data" is true.

ROM stands for Read Only Memory. ROM is a type of computer memory that is non-volatile, meaning the data stored in it is not lost when the power is turned off. It is called "Read Only" because the data stored in ROM can only be read and cannot be modified or erased. ROM is commonly used to store firmware, which contains the instructions that are permanently programmed into a device.

The biggest advantage of using a notebook is portability. Notebooks are compact and lightweight, making them easy to carry around. This allows users to work or study on the go, whether it's in a coffee shop, library, or while traveling. Portability enables flexibility and convenience, as users can access their files and applications wherever they are. Additionally, notebooks often have long battery life, further enhancing their portability by eliminating the need for constant charging.

A virtual storage system allows users to store data remotely, typically in a cloud-based environment. This means that the storage system can be located at a location such as your ISP (Internet Service Provider), where you can access and store data from anywhere in the world. This flexibility and accessibility are key features of virtual storage systems, making the statement true.

The correct answer includes examples of storage devices such as a hard drive, DVD-ROM, and flash drive. These devices are all capable of storing data and information for later retrieval. A hard drive is a permanent storage device found in computers, while a DVD-ROM is a removable storage device that can be used to read data from DVDs. A flash drive, also known as a USB drive, is a portable storage device that can be easily connected to different devices to transfer and store data.

DOS stands for Disk Operating System. It is a computer operating system that was widely used in the 1980s and 1990s. DOS primarily operated on IBM PC compatible systems and was known for its command-line interface. It was responsible for managing the computer's disk storage and executing applications. DOS played a significant role in the early development of personal computers and laid the foundation for modern operating systems.

Supercomputers are typically used for scientific and engineering tasks, as they have the capability to process large amounts of data and perform complex calculations. They are also used for forecasting weather and animation, as these tasks require immense computational power. Additionally, supercomputers often have specialized software programs that are designed to optimize their performance and cater to their specific tasks. Therefore, the correct answer is "All of the above".

The correct answer is MHZ, which stands for megahertz. Megahertz is a unit used to measure the speed of a processor. It represents one million cycles per second. This measurement is commonly used to compare the processing power of different computer systems.

RAM, or Random Access Memory, is considered volatile because it loses all data stored in it when the computer is shut down or reset. Unlike other types of memory, such as hard drives or solid-state drives, RAM does not retain its contents when power is removed. This is because RAM relies on electrical currents to store and retrieve data, and without power, these currents are disrupted and the data is lost. Therefore, RAM is temporary and meant for short-term storage while the computer is powered on.

A CD (Compact Disk) can usually store up to 700 Mb of information. This is a standard capacity for CDs and allows for the storage of various types of data, such as music, videos, documents, and software. The high storage capacity of a CD makes it a popular choice for distributing and archiving large amounts of data.

A gigabyte is equal to 1024 megabytes because in the binary system, each unit is multiplied by 1024 instead of 1000. Therefore, when converting from gigabytes to megabytes, we multiply by 1024.

Since the resume is only half a page long in Microsoft Word, it would require a very small amount of memory to store. A kilobyte (KB) is the smallest unit of memory commonly used, and it is sufficient to store a resume of this size. A gigabyte (GB), megabyte (MB), and terabyte (TB) are much larger units of memory and would be excessive for storing a half-page resume.

To access a remote storage system, the correct way is to log on with a valid ID and password. This is because remote storage systems are usually protected and require authentication to ensure only authorized users can access the data. Starting a web browser and navigating to the site may not necessarily grant access to the remote storage system, as it depends on the specific setup. Using an e-mail program or a USB memory key is also unlikely to provide access to the remote storage system, as these methods are typically used for transferring or storing data rather than directly accessing the system.

ROM (Read-Only Memory) is a type of computer memory that retains its stored information even when the power to the system is turned off. This is because ROM is non-volatile memory, meaning it does not require power to maintain its data. Unlike RAM (Random Access Memory) which is volatile and loses its data when power is lost, ROM is designed to store permanent or semi-permanent data that is essential for the system's operation, such as firmware or system instructions. Therefore, ROM is the correct answer as it retains information even when the power is off.

The correct answer is "Storage" because it encompasses all the various media on which a computer system can store software and data. This includes devices such as hard drives, solid-state drives, optical discs, USB flash drives, and network-attached storage. The term "storage" is a more general and inclusive term compared to the other options listed, which only refer to specific types of storage media.

A high density (HD) floppy disk can hold 1.44MB of data. This was the standard storage capacity for HD floppy disks, which were commonly used in the past for storing and transferring files. The other options, 1.88MB and 2GB, are not correct as they do not accurately represent the storage capacity of an HD floppy disk. The option "Any" is also not correct as it is not a valid answer to the question.

A modem is used to connect two computers using telephone lines. It allows for the transmission of data between the two computers by converting the digital signals from one computer into analog signals that can be transmitted over the telephone lines, and then converting the analog signals back into digital signals that can be understood by the receiving computer. This enables communication and data sharing between the two computers over a telephone network.

When purchasing a computer for someone who works with video files, the amount of RAM is an important factor to consider. Video editing and processing require a significant amount of memory to handle large file sizes and perform tasks smoothly. Sufficient RAM allows for faster data transfer and processing, reducing the risk of lag or crashes during video editing. Therefore, considering the amount of RAM is crucial to ensure an efficient and smooth video editing experience.

Closing any files and application programs that are not currently being used is the best way to gain more RAM for processing a newsletter. When files and applications are open, they consume memory resources, and closing them frees up RAM for other tasks. Restarting the computer can also help in freeing up RAM, but it is not the most efficient solution as it may close all running processes and disrupt other ongoing tasks. Therefore, the first two options are the correct ones for gaining more RAM.

The operating system is the software that manages and controls the computer's hardware and software resources. Internet Explorer and Microsoft Word are not operating systems; they are applications that run on an operating system. Microsoft Windows 3.0 and Windows 8, on the other hand, are operating systems that can be used on a computer.

You can use any of the above options to copy pictures from one computer to another. An external hard drive, memory card from a digital camera, or a USB memory key can all be used as removable storage devices to transfer pictures between computers.

All of the options listed (refrigerator, coffee machine, microwave, and entertainment system) can have a computer chip embedded as part of their equipment. These household appliances often have advanced features and functionalities that require the use of a computer chip to control and monitor various operations. For example, a refrigerator may have a computer chip to regulate temperature and control defrost cycles, while an entertainment system may have a computer chip to process audio and video signals. Similarly, a coffee machine and microwave can also have computer chips to control brewing settings and cooking times, respectively. Therefore, any of the above options can have a computer chip embedded in them.

Saving files to a storage device is important for several reasons. Firstly, it helps prevent data loss if the computer is turned off unexpectedly or experiences a power outage. By saving files to a storage device, you ensure that your data is protected and can be easily recovered even if the computer shuts down abruptly. Additionally, saving files to a storage device allows you to store information from the computer's RAM onto the device, freeing up memory and improving the computer's performance. Lastly, saving files to a storage device provides you with a copy of the data, allowing you to access and use it on different devices or in case the original files are accidentally deleted or corrupted.
