Computer Hardware

CPUs usually weight between 100-200 grams.

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.

Aaaa

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.

In the case of a desktop computer a power supply that in turn plugs into a household outlet provides power to the internal components of the computer. In the case of a laptop or tablet a battery provides power.

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).

traffic signal, sign etc

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's a track (a section of a magnetic disk, or a section of any given storage device that emulates a magnetic disk that uses the the LBA/CHS[Cylinder, Head, Sector]) that the computing device dedicates to store parity data (data to aid in error verification/correction for data that is stored on the disk).

Peripherals are external devices that are attached, either by a cable or wifi, to the computer. Examples of peripherals are a keyboard, monitor, mouse, printer, external hard drive, and so on, all of whom are attached externally to the computer's tower and motherboard.

BIOS configuration data is stored in CMOS memory. That is where all the basic hardware settings are kept. CMOS has traditionally been volatile memory, so a battery is required. Newer BIOSes often use NVRAM.

A 'Hertz' is a cycle of once a second.

A megaHertz is a million cycles per second.

IBM stands for International Business Machines. They are located in Armonk, NY, and were the first to create the PC standard. Then other companies begin to copy the PC standard. That was ruled as legal in the lawsuit between IBM and Tandy Corporation (who then owned Radio Shack). The fact that someone asked this shows that IBM no longer dominates the PC world, when they are the ones who we should thank for PC compatibles.

A keypad is an input device.

The cloud is a server usually somewhere in the world. When you upload files to the "Cloud" you are sending them to a secure server where they are stored safely until you call upon them. This helps free up device storage and makes the files accessible from anywhere with a internet connection.

No, just let monitor go to sleep unless you will be away for more than a couple days. Many computer experts say it is better for you to leave it on then reboot daily.

No, processor size depends on manufacturer and model. Quad-core basically means that a processor can execute 4 different things at once, and is more closely related to processing capability and not size.

The thickness of a processor is normally referred to the die thickness (very small measurements) while the form factor refers to how it physically will connect to the motherboard and thus more representative of overall shape.

An x-ray machine would be an input device in terms of data collection because it gets its data from the patient. It would also be an output device because it gives an image that a doctor can use. And yes, x-ray machines do broadcast radiation through a patient. But that is part of the process of collecting the data and not the primary intention.

Atlantic, gulf ports , and Mississippi River.

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