The ROM chip contains the BIOS, which tells your computer how tostart●Power-on self test (POST) - At startup, a sequence that tests all computer componentsfor proper operations.●Firmware - The instructions on the ROM chip●Virtual Memory - In computer concepts, the capability of an operating system totemporarily store data on a storage medium until it can be "swapped" into RAM.●Swap File - Data that cannot fit in RAM and uses an area of the hard disk called virtualmemory. (AKA paging file)●Input Device - Communicates instructions and commands to a computer. Common inputdevices are keyboard, mouse, stylus, scanner, microphone and game controller.Touchscreen●Output device - Conveys information from the computer to the use. Common outputdevices include displays, speakers, headphones, projectors, and printers.

Which of the following types of RAM needs to be constantly recharged to retain the contents? What type of hard drive has no moving parts, making it fast and durable? Which of the following factors can affect processor performance of a CPU? What determines the speed at which data travels? Where on a computer is the operating system generally stored? Which of these is an optical medium of storage? Which of the following devices is the easiest to upgrade, such as by adding RAM? What is the recommended solution if a computer performs slowly? Freeing up disk space and increasing RAM capacity improves a computer’s performance. When a CPU executes instructions as it converts input into output, it does so with _____. the control unit and the arithmetic logic unit What does an operating system provide so you can interact with a device? Which of the following features is a way to make a computer do what you want it to do? One way to make a computer do what you want it to do is to use a menu. In Windows, you use _____ to reorder, move, and navigate between folders. File Explorer or file manager A file manager is used for all of the following except ____. You can use a file manager to reorder, move, or navigate between folders. When does the boot process start? when you turn on your computer What is the most common type of volatile memory? Which of the following terms refers to the area of the hard drive used for virtual memory? Which of the following statements is true about the Clipboard? It is temporary storage that holds a selection until you paste it into a document or folder. What is the main purpose of an operating system? The operating system is responsible for coordinating the resources and activities on a computer. It is a go-between for you and the computer. It also manages interactions between hardware and software. Finally, it directs internal components. Which of the following can you run to find and remove unnecessary files? Where can you pin frequently used apps for easy access? Operating systems allow you to make adjustments such as pinning frequently used apps to the taskbar for easy access. How is an executable file different from a data file? Unlike a data file, you cannot open and read an executable file.

Which types of RAM needs to be constantly recharged to retain the contents?Each DRAM cell has a charge or lack of charge held in an electrical capacitor. This data must be constantly refreshed with an electronic charge every few milliseconds to compensate for leaks from the capacitator.
Which type of memory is permanently?5. ROM. Read-only memory (ROM) is another type of primary internal memory, but unlike RAM, ROM is non-volatile and stores data permanently. It does not depend on the device to be turned on in order to save data.
Which type of memory is permanently installed in your computer and attached to the motherboard?2) ROM Computer Memory
It is a very fast type of computer memory which is usually installed close to the CPU on the motherboard. ROM is a type of non-volatile memory, which means that the data stored in ROM persists in the memory even when it receives no power – for example when the computer is turned off.
What is the most common type of storage device for transferring?USB flash drives are small (roughly the size of a pack of gum), portable storage devices that are most commonly used for transferring files from one computer to another. No installation is required and no additional software is needed to transfer files to or from a USB flash drive.
