Desktop computer weight?

Hello, I am just going to tell you that there are many different types of computers, which range from different sizes, and weights, to get a accurate answer if I were you I would go to a local Store, as of (Walmart) and see if they let you look at the computer to see if you like it, and maybe from that day you will learn a little more about a computers weight.

Hope this helped,

Is a monitoran output or input devise why?

A monitor is first and foremost an Output Device because it displays information already held in the computer. Touchscreen monitors that allow you to input information or to use navigational features such as menus, icons and so on are also Input Devices. Another example of a device that is both an input and output device is a joystick with Force Feedback technology.

Is a USB an input or output device?

A USB Flash drive is considered a storage medium. Data can be both read, stored, and sent to / from a USB Flash drive, but it does not in itself input or output any data.

Where is the cheapest webcam?

To find and possibly purchase a cheap laptop webcam, one can consult Amazon or any other general online mall. Stores, be it online or physical, concrete stores, will most likely carry any item. A cheap laptop webcam is no exception.

Why is the touchscreen considered as an output and input device at the same time?

It is considered an output, because you can view results on the display. It is an input, because when you touch the screen, you are executing commands or inputting data into the computer, much like you would've typed on a keyboard or clicked on a mouse.

Is modem input or output devices?

Both. Modem stands for

MOdulator DEModulater.

Modulator comes from modulation which is the process of converting analogue data to digital for transmission and Demodulator from Demodulation, converting digital signals to analogue.

Digital data-discrete or non-continuous data

Analogue data- continuous or non-discrete data

Is a video cable an input or output device?

A TV displays information to you, so it is an output device.

Of course, some televisions have advanced ways for the user to interact with them, such as buying pay-per-view channels using only the TV remote. These types of televisions can also be considered input devices, as you are sending information to your cable company.

How do you connect a laptop to a TV?

First, u need to get a cord that fits Your TV an your laptop. I used an HDMI cable. if you turn on ur laptop and put it to the right input (VGA) it may say no signal. All you have to do is select safe mode with networking on the laptop. The only bap problem about this is if you wanna listen to music yyou cant. Im currently trying to find that out.

How do you determine if a problem is hardware or software?

Hardware problems usually mean that the computer itself is having difficulties, such as physical damage to the devices within your desktop.

Software problems are usually errors caused by malfunctions with programs that run on the computer and not the computer itself, such as a bug in programming or heavily fragmented files.

How many minutes of video time on 1 GB memory stick?

Someone else: "13 minutes."

It depends on the resolution of the video you are uploading. If you're going for Red Cam HD full resolution at 4k then a 64G card will only hold about 4min. If you do slow motion at this resolution, ie. more frames per second, like the Phantom camera's 1000 frames per second, it's going to fill a whole teradrive in about 2-4 seconds and take about 10 minutes to get from the camera to the computer to the viewing screen via fiber-optiic cables just to get processed. If you're going for something smaller like 640x480 pixels non-HD then the 1BG card is going to last a lot longer. Probley about 20 min?

What are the four possible configurations for a PATA drive installed in a system?

Primary Master

Primary Slave

Secondary Master

Secondary Slave

Primary or Secondary will depend on which cable are you using to connect the drive.

Master or Slave will depend on the drive's jumper configuration.

What is the importance of the computers fan?

Basically what a computer fan do is pull the heat from the heatsink that is connectted to the CPU and escorts it out of the computer,, because if the CPU gets to hot then the computer just stop working.

What does SCSI stand for?

SCSI stands for Small Computer System Interface. It is a set of standards used by computer engineers to physically connect and transfer data between computers and other devices.

How is text stored in a computer?

In a computer, everything is stored in ones and zeros. A single one or zero is called a bit, and a group of 8 bits is called a byte. One byte can be represented as 8 binary numerals, like this: 10011101 Which equals the number 157. It can also be represented in hexadecimal, like this: 9D One byte can store any number between 0 and 255 (00 and FF in hex). In a computer, every text character has a specific number that represents that letter. So, when it sees a particular hex number, it translates that into the text and displays it.

This is an overly simplified description. To learn more, read up on bits, bytes, ascii codes and data storage protocols.

Where is the mic in your PC?

What type of expansion slot is always used for high speed 3D graphics video cards?

PCI express x16

Is the absolute fastest at the moment.

If you want to be crazy buy a motherboard that supports ATI crossfire or nVIDIA SLI, where upto 4 Cards can be ran at the same time.

Give you a diagram of the 3 components of CPU?

The CPU is comprised of three main parts:

ALU (Arithmetic Logic Unit): Does the actual logical comparisons that need to be processed.

Control Unit: Can execute or store the results coming out of the ALU.

Registers: Stores the data that is to be executed next.
THE alu and the control unit or memory and the ALU.

The Control Unit and the Arithmetic - logic Unit (ALU).

1)hard disk

2)processor

3)motherboard

4)ROM-random acces memory

5)ROM-read only memory

6)varius ports

7)floppy drive

8)varius resistors

9)cables

10)bios

What occurs during a power-on self test?

The Power On Self Test is the series of operations that an electronic device performs after it has been switched on. These steps are very much dependant on the device and the manufacturer and are different in every type of electronic device.

How many instructions can an modern CPU process per second?

no

-----

How about a real answer?A modern processor, say, the i7 3770k, is capable of processing 3.5 Instructions per CYCLE. And it runs at 3.5GHz, or 3,500,000,000 Cycles per Second. This becomes:

3.5 *3.5 Ghz= 12,250,000,000 Instructions per Second. And now I need to put my head on ice! You cold word this as 12.25GIPS, or 12.25 Giga-Instructions per Second. Of course, GIPS isn't a real abbreviation, so use what you want to!

You can also go by GFLOPS, or Giga Floating Point Operations Per Second, a more common measurement.

That same i7 3770k is capable of something like 150GFLOPS, or 150,000,000,000 Floating Point Operations per Second.

Amazing!

How many pins does IDE standard connector have?

It depends, ones for hard drive are i think, about 40 pins, an less for the floppy IDE cable Desktop hard drives have "40" pin connectors; however, the actual number of pins is 39. There is one pin missing in the upper row, middle. I believe the reason for this is so the ribbon won't be connected upside down, it can only go one way.

Can pen drive be used as a graphics card?

No it can not you will need to buy a graphics card there is no other way besides On board Graphics

Which one is best lcd or tft?

TFT, which stands for Thin Film Transistor, is not really different from LCD. TFT, comes from the family of the LCD technology. It is a variant of LCD, it is a modern version of the LCD technology. TFT, has a very well improved image quality and makes use of active matrix addressing.
HI I ASKD DIS SAME QUES TO D PERSON WHO ASSMBLD MY PC.....HE SAID V USE DESE WRD INTERCHANGEABLY......BOTH MEAN D SAME!! DATS WAT HE SAID

A liquid crystal display (commonly abbreviated LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It is prized by engineers because it uses very small amounts of electric power, and is therefore suitable for use in battery-powered electronic devices. I think in this whenver the person see the movie or image other than 90 degree it looks blackish images

TFT-LCD (Thin Film Transistor-Liquid Crystal Display) is a variant of Liquid Crystal Display (LCD) which uses Thin-Film Transistor (TFT) technology to improve image quality. TFT LCD is one type of active matrix LCD, though it is usually synonymous with LCD. It is used in both flat panel displays and projectors. In computing, TFT monitors are rapidly displacing competing CRT technology, and are commonly available in sizes from 12 to 30 inches. As of 2006, they have also made inroads on the television market.In this the picture quality can be improved to some extent whenever the person see the image or movie other than 90 it doesnt look like blakish as compare to lcd
TFT (Thin Film Transistor) is a type of LCD display. Since one is a subset of the other, it is not possible to list differences between them.
