Computer Hardware

A "serial to parallel" converter converts a serial data connection to a parallel data connection. For example, in computer storage, there are controller chipsets that convert SATA (Serial ATA) to PATA (Parallel ATA, also called IDE or EIDE).

The bios should just go to your last saved settings if you just close out of it.

A 4-pin fan header is a PWM (pulse-width modulation) fan header. As opposed to a traditional 3-pin, a 4-pin is more sophisticated in the way it controls fan speed. The 3-pin fans use DC (power) control. Unfortunately if you have a fan that has LED lighting with a 3-pin header the lights will dim with along with the decrease in fan speed, and vice versa. The fourth pin allows digital (PWM) control without having to power down or power up the entire fan itself.

It is the monitor that can show output. The printer also shows an output on paper.

CPUs usually weight between 100-200 grams.

The page of text is first scanned and then an Optical Character Recognition (OCR) software program is used to convert the scanned text file into a machine-encoded text file that the user can edit and make changes to. So the device is a scanner, usually a flat-bed scanner, or a hand-held scanner, or a printer that has an inbuilt scanner.

eee

The port is a USB (Universal Serial Bus).

The USB port is hardware.

1.05 x 1024 = 1075.2 MB

A "diskette" or "floppy disk" is neither as they are removable magnetic storage media. However, if you refer to the drives that read from them or write to them, then those drives are considered hardware.

it is a touchscreen item

A USB stick is both an input and an output device. Data can be written to the stick, and can be extracted from the stick.

1. Can the device be physically connected to the computer.

2. Does the device come with driver software to enable it to 'talk' to the computer.

3. Is the cost of the device prohibitive for the amount of use it will get.

4. Are replacement sundry items (inks etc) reasonably prices.

The silicon is a semiconductor and can be doped to control its conductivity and create the junctions needed to make diodes and transistors. These diodes and transistors can act as switches and logic gates in properly designed circuits. Silicon can also be easily oxidized to become a robust waterproof insulator to passivate and protect the circuits and components beneath it.

The aluminium and/or copper are just good conductors used to "wire" the silicon components together and provide pads that can be used to attach wires or metal beads so that the chip can be connected to external circuits.

This is a PnP (Plug & Play) device! You don't need any drivers or software to use it. I have used this kit many times and it's been a life-saver in several occasions. It is well worth the price. Definitely a must-have tool for any IT or computer tech.

Aaaa

The Compaq Presario CQ5210F has only one legacy PCI slot,but it has three PCI Express slots (1 x16 and 2 X1)

Composite Video (RCA jack plug, or F-pin)

S-Video (Super-Video)

Component Video.

DVI (Digital Visual Interface)

HDMI (High Definition Multimedia Interface)

USB 3.1 (C) can deliver a power output of up to 100 watts (20 volts and 5 amps).

wireless. but it depends on the power of the controller for each device.
