Computer Hardware

There are four pins in a USB port.

The positive, negative and Data positive, data negative.

There are a number of different avenues and types of data that can be entered into a computer system. Assuming you are simply talking about naming five different interface devices the list might contain the following:

Keyboard

Mouse

Touch Pad

Touch Screen

Microphone

Data Storage Medium such as a flash drive, hard drive, etc.

Video Camera

etc.

== == Actually, 1 gigabyte should be 1,024 megabytes. But either way, the previous answers stand. Not nearly as big.

no.

no 1GB is 1,000MB. 1.5GB equates to 1500MB, which is much more than 10MB. So no, it isn't anywhere near as big.

A Central Processing Unit is the main processor in a computer that processes all the logic statements put to it.

It is responsible for all the processing of the computer unless there is another process that does the job like a Graphics Processing Unit or Physics Processing Unit.

If you turn off your computer for 12 hours a day you could save 87.50 in one year. So if you work in an office and 10 employees do this you could save 1000 dollars a year

Look at it this way,

Say a application needs something computed by the CPU. That application says to the CPU, "I'm going to send you 500 pieces of data, so I need a space in the memory that is 500 pieces of data big." So the CPU takes a look at the memory. Initially there is room for 10,000 pieces of data, but because there are other processes already running the first 1 - 2,000 pieces are already taken up. The CPU says to himself from piece 2,000 to 2,500 is were all new data is going to go.

The physical memory is the address from 2,000 to 2,500.

Now the application doesn't realize that there are other processes that the CPU is taking care of. All it sees is the data 1- 500 pieces stored in the memory. This is logical memory.

When the application wants to run a piece of data of the 1-500, its says to the CPU run the piece 130. In reality 130 is not even a space in the memory that the CPU has set out for the application. Because remember it was originally 2,000-2500 that was set aside for the application. Piece 130 according to the applications logical memory is in reality piece 2130 in the physical memory. So when the CPU is receiving instructions from the application it has to translate the logical memory in to the physical memory and then back into the logical when replying to the application.

I use Wondershare DVD Slideshow to create slideshows. It's a free, easy-to-use and powerful. There are many attractive transition effect provided for choice, and you can add background music, add text or subtitles.

Since 1 megabit 1mb = 1,048,576 bits

1024 kilobits = 1mb

2048 kilobits = 2mb

If you meant kiloBytes KB (which is 1/8 kilobits)

256 KiloBytes = 2mb

i.e. a download speed of 2 megabits/sec = 256 kiloBytes/sec = 1 megaByte every 4 seconds.

USB version 1.1( sometimes called Basic speed USB or Orginal USB) allows for two speesd,1.5 Mbps and 12 Mbps. USB version 2.0 (sometimes called hi-speed USB or USB2) allows for up to 480Mbps.

A microphone is a device with an electrical output. An acoustic wave is the input. Its only function is to 'capture' sounds and convert them into an electrical signal for processing by the computer.

Wifi is a standard wireless network protocol. There are many different versions, 802.11a 802.11b all the way up to 802.11g (and now theyve skipped several letters & gone straight to 802.11n). A "wifi card" would be an addon card which adds wifi functionality to a computer... The phrase "wifi card" is also sometimes incorrectly used for USB wifi interfaces, even though they arent technically a card.

The generic phrase "PC card" could refer to any of a number of different types of cards. However, it is most often used to refer to PCMCIA type cards, which are addon cards specifically designed for use in notebooks. PCMCIA cards are about the size of a credit card (albeit much thicker) and slide into the PCMCIA slot on a notebook computer. This is preferrable to USB in that PCMCIA cards insert fully (or near fully) into the body of the computer, as opposed to USB addons which usually protrude from the machine & must be removed for travel.

So most likely the phrase "Wifi PC card" refers to a PCMCIA 802.11 wireless network card.

No one person has been given credit for inventing input devices. These have changed over the years, but have always been necessary for getting information into computers.

Replace the power supply. Power supplies are pretty inexpensive and usually range $40-$60 for 400watts. Recommend you replace this as soon as possible. NOTE: the power supply is one of the four components which require a fan as it builds up alot of heat. The other three are processor, video card, and the case itself.

In one GigaByte, or GB, there are 1,000 Mega Bites, or MBs. More acurately, a computer can only count by 2's (base 2). A person counts by tens. One, ten, one hundred, one thousand etc. A computer counts by twos. One, two, four, eight, 16,32,64,128,256,512, 1024. 1024 is so close to 1000 that most people refere to 1K as 1000 when actually it is 1024. there are 1024Mbytes in 1 Gbyte. 1G =1024M, 1M=1024K, 1Kbyte=1024bytes. There are 1000*1000*1000bytes in 1Gbyte(1,000,000,000bytes in 1gigabyte), or more acuratly (1024*1024*1024) or 1,073,741,824bytes in a gigabyte. There are 1024MBytes in 1GB

Because it is an external device connected to the computer that translates user input into output on the screen.

• Sharing system resources requires operating system to ensure that an incorrect program cannot cause other programs to execute incorrectly.
• Provide hardware support to differentiate between at least two modes of operations.
• user mode - Execution done on behalf of a user.
• Monitor mode - Execution done on behalf of operating system.
• Mode bit is added to computer hardware to indicate the current mode : monitor (0) or user (1).

That really depends on what you expect to do. If you only need to run office applications, chat and send email and save a few thousand pictures you will probably do really well with 500GB. If you need to back up other systems on your network or get into serious video editing, you will run out of space fairly quickly.

standard RCA cable harness (the red white and yellow cables) are likely to be used for a DVD Player, you could also use a tv tuner and coaxile cable if you use and RF modulator. ---- Actually this question is referring to question 20, Chapter 10, Guide to Managing & Maintaining Your PC, Sixth Edition by Jean Andrews. The answer is referenced on p438. The answer is the blue port(Line-in) which is also used for Music Synthesizers, a microphone, CD Player or other external device producing sound.

A FD (flashdrive) is a portable data storage device that uses flash memory. A USB port is a port for a USB cable or anything that has USB capabilities, to plug into. For example, a FD normally plugs into a USB port.

Electric currents flowing at higher rates than the material can withstand.

PCI- E, AGP and PCI are the different slots on your motherboard that the graphics card can go into, and different GPUs fit in one of these slots. PCI - E is the fastest port at the moment, so AGP and PCI video cards are declining. All computers have quite a few PCI ports but most modern motherboards have PCI - E ports and not AGP. If you are buying a GPU, you will need to check what ports your motherboard has, so you know it is compatible. SLI is nVidia's dual graphics card system, and only selected motherboards support this. An SLI compatible video card can be used together with another SLI compatible video card in an SLI compatible motherboard.
