Who invented computer scanners?
The pantelegraph (Italian: pantelegrafo; French: pantélégraphe) was an early form of facsimile machine transmitting over normal telegraph lines developed byGiovanni Caselli, used commercially in the 1860s, that was the first such device to enter practical service. It used electromagnets to drive and synchronize movement of pendulums at the source and the distant location, to scan and reproduce images. It could transmit handwriting, signatures, or drawings within an area of up to 150 x 100mm.
Édouard Belin's Belinograph of 1913, scanned using a photocell and transmitted over ordinary phone lines, formed the basis for the AT&T Wirephoto service. In Europe, services similar to a wirephoto were called a Belino. It was used by news agencies from the 1920s to the mid-1990s, and consisted of a rotating drum with a single photodetector at a standard speed of 60 or 120 rpm (later models up to 240 rpm). They send a linear analog AM signal through standard telephone voice lines to receptors, which synchronously print the proportional intensity on special paper. Color photos were sent as three separated RGB filtered images consecutively, but only for special events due to transmission costs.
When would you disable the serial port?
In the past, both the serial and parallel port were the most common means of data transfer and communication used by PCs. Serial ports were used for devices such as modems, mice, and serial port printers. However, in newer PCs, both the serial and parallel ports have been replaced by the use of USB ports. You should only disable serial port(s) if you are absolutely certain that auxiliary devices such as modems; printers; mice; etc.. are USB based and that your PC has enough USB ports to accommodate all of your auxiliary devices. Note: If at some point in the immediate future, you plan to sell your PC, it might be wise to leave the serial port as is.
What is a hardware components of DBMS?
Hardware components of a DBMS include the server where the database is stored, processors for computing data operations, memory for temporary storage of data, storage devices like hard drives or SSDs for persistent data storage, and network devices for communication between client and server.

List 5 safety precautions for lifting weights?
Resistance training is the best way to build power. Just make sure you don't just train any muscle, but train those muscles that you need in softball. That includes muscles in your arms, shoulders, legs, wrists, as well as your core muscles.
The Generic USB Hub is a HI-SPEED USB device and will function at reduced speed when plugged into a non-HI-SPEED port
A PVR (Personal Video Recorder) is a device used to record and store digital video recordings of television content. It allows users to watch programs at their own convenience and to pause rewind and fast forward their favorite shows. A PVR can also be used to store movies and other digital content.
The main features of a PVR device include:
- Record and store digital video content
- Pause rewind fast forward and search content
- Store movies and other digital content
PVR devices offer users the convenience of being able to watch their favorite shows and movies at any time. They are also great for saving time by skipping commercials and saving space by recording multiple shows at once.
What is the difference between instruction pipelining and arithmetic pipelining?
Arithmetic pipelines differ from instruction pipelines in some important ways. They are generally synchronous. This means that each stage executes in a fixed number of clock cycles. In a synchronous pipeline, moreover, no buffering between stages is provided. Each stage must be ready to accept the data passed from a previous stage when that data is produced.
Another important difference is that an arithmetic pipeline may be nonlinear. The "stages" in this type of pipeline are associated with key processing components such as adders, shifters, etc. Instead of a steady progression through a fixed sequence of stages, a task in a nonlinear pipeline may use more than one stage at a time, or may return to the same stage at several points in processing.
Explain why a particular piece of software will not run on all computers?
Because are all computers the some? NO. if you did it on a Laptop, then put it on a USB and put it in a Apple it doesn't do it the same way.
What is the purpose of the capacitor at the input and output?
In cascade connection, it can be a AC coupling capacitor at both end to isolate the circuit. Isolating DC from input side or DC single to load side if they are at different reference supplies. If pull down to ground, it can be a protective capacitor for overshoot when capacitance is big enough, or can be used for shorting high frequency to ground to restrain pulse jamming when capacitance is small. It's value depends on the application, and it's influence to the circuit like slew rate and some chip's maximum capacitance load should be considered.
Of course they are, they have a computer boards that are programmed for payouts.

What does 'PXE-E61 Media test failure' mean?
It has multiple connotations. If you actually know what PXE is and were planning to use it, it simply means that something is wrong with the network cable, or the router is not turned on.
If you have absolutely no idea what PXE is or why you would want it and just want to know why your computer doesn't start up, it means that either your hard drive has been formatted or died, or that "LAN" was set up as the first boot device in the BIOS. If the BIOS detects that there is no hard drive or it isn't bootable, it will continue through the list of boot devices, including the network. PXE is basically the ability to boot an operating system that is stored on another computer over the network. It is very useful for businesses and power users, but most consumers will never actually use it.
BIOS is checked out when computer is switched on and reports configuration, if set as 1st boot device hard drive at Bios boots here, if Bios is set to another device it boots there, 1st boot sequence is your 1st boot choice, if hard drive is the choice initialization activates a mechanical arm where mounted on its end is a head configuration comprising of magnetic small boxlike shapes the arm and its associated parts directionalises its self over to the outside cylinders on the platter/plate associated with the disc in the hard drive and attempts to read a ring of coded data and locates sector 1 and an area of data where reading executes from MBR (MASTER BOOT RECORD) and tells computer what PARTITION to boot in this case it is drive "C". Since "C" is active partition on after the scan boot reports on 2 "FILE ALLOCATION TABLES" known as FAT and provides size, here is the record recordings of files on hard disc, after reading the 1st FAT, 2nd FAT contains "ROOT DIRECTORY" where 2 hidden system files are located and a "KEY FILE" called "COMMAND.COM" boot process initializes windows start. PARTITIONING can in hard drive takes on other assigned letters "D" "E" "F" ETC. Where no partitioning has occurred next hardware device CD-ROM IS assigned the letter "D", and this can be your 1st BOOT device rather than hard drive, it's optional. A VIRUS can replace MBR with themselves and replace MBR somewhere else.
What is acpi multiprocessor PC?
An ACPI processor helps the computer recognized motherboard, hardware and drivers. It just replaces the old AMP standard.
What are the differences between digital and analog circuits?
Analog circuits operate on a continuous range of voltages. For example, an audio signal may range anywhere from 0V to 1000mV, and an infinite number of places between. Digital circuits operate on only one of two states: "off" or "on", typically represented as 0 and 1. These on and off states are represented by different voltages in different systems. But any given digital signal will have one of only two distinct values. For example, a typical digital signal will dictate that anything below 1.0V is considered "off", and anything above 4.5V is considered "on". Information in digital circuits is represented as either a consecutive stream of these on and off states ("serial") (ex: 10010110) or a set of signals together representing a value ("Parallel") where 8 wires represent 8 bits of a one byte value.
What is the strength of current in each resistor of a series circuit?
The current in each resistor in a series circuit is the same. Kirchoff's Current Law states that the sum of the currents entering a node must add up to zero. The connection between two resistors in a series circuit is a node. The current entering the node from one resistor is equal to the current leaving the node into the next resistor.
