When you are discussing the memory capacity of a memory module, the capacity is specified in
Memory module capacities are typically specified in an a-by-b format. Under this format, the capacity of the device (in bytes) is derived by multiplying the two numbers and then dividing by eight (or nine for memory modules with parity chips). How many devices can a single USB hub support?
The universal serial bus (USB) is a high-speed serial interface that has been developed to provide a fast, flexible method of attaching up to 127 peripheral devices to the computer. USB peripherals can be daisy chained or networked together using connection hubs that enable the bus to branch out through additional port connections.
You are helping a nontechnical user over the telephone and you need to have the user plug in the SVGA monitor. How would you describe the connector and number of pins in the SVGA connector?
A.15-pin, 3-row, D-shell
The monitor is attached to the video adapter card in the system unit via a signal cable or cables. The signal cable permits the monitor to be positioned away from the system unit if desired. With CRT monitors, the signal cable is permanently attached to the monitor and plugs into the video adapter card using a 3-row, 15-pin, D-shell connector.
How is information stored in the system’s BIOS updated?
C.By electronically flashing the BIOS with new information
When the microprocessor is upgraded, the BIOS should be flashed with the latest compatibility firmware. If the BIOS does not possess the flash option and does not support the new microprocessor, a new BIOS chip that does support it must be obtained. If not, typically the entire system board will need to be upgraded.
Which one of the following types of memory can be used to permanently store data and instructions?
ROM devices store information permanently and are used to hold programs and
