Can a laptop be charged via USB port?
Nothing prevents the design of a netbook which can draw power from a USB host, similar to the way many smart phones or tablet computers do.
However, most PC, laptop or netbook devices are designed as USB host devices, providing (limited) power to and managing communications with USB peripheral devices such as flash memory sticks, digital cameras, keyboards and some-such.
Ports of Auckland provides a full range of cargo-handling and logistics services at two seaports - one on the east coast adjacent to the Auckland central business district, the other on the west coast in Onehunga - and a strategically located inland port at Wiri, South Auckland.
By value of trade handled, it are New Zealand's most significant port. In 2009, it handled cargo the equivalent to 15% of the country's total GDP - twice as much as any other New Zealand port. It is the country's largest import port,
Ports of Auckland operates in three locations in the Auckland region - New Zealand's economic hub.
It's Auckland seaport is New Zealand's largest container port, handling more than 840,000 20-foot equivalent container units (TEU) per annum. Its total container volumes represent 49% of the North Island container trade and 36% of New Zealand's total container trade.
Ports of Auckland's General Wharves handle 2.7 million tonnes of bulk and breakbulk (non-containerised) cargo each year, including 67% of the total vehicle imports to New Zealand.
The Port provides towage, pilotage and linesman services on the Waitemata and Manukau Harbours, where it services upwards of 1,600 ship calls each year - on average four to five ships a day.

A network card, network adapter, network interface card or NIC is a piece of computer hardware designed to allow computers to communicate over a computer network. It is an OSI model layer 2 item because it has a MAC address. Every network card has a unique 48-bit serial number called a MAC address, which is written to ROM carried on the card. Every computer on a network must have a card with a unique MAC address. The IEEE is responsible for assigning MAC addresses to the vendors of network interface cards. No two cards ever manufactured should share the same address. Whereas network cards used to be expansion cards to plug into a computer bus, most newer computers have a network interface built into the motherboard A separate network card is not required unless multiple interfaces are needed or some other type of network is used. The card implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as ethernet or token ring. This provides a base for a full network protocol stack, allowing communication among small groups of computers on the same LAN and large-scale network communications through routable protocols, such as IP. There are four techniques used for transfer of data, the NIC may use one or more of these techniques. * Polling is where the microprocessor examines the status of the peripheral under program control. * Programmed I/O is where the microprocessor alerts the designated peripheral by applying its address to the system's address bus. * Interrupt-driven I/O is where the peripheral alerts the microprocessor that its ready to transfer data. * DMA is where the intelligent peripheral assumes control of the system bus to access memory directly. This removes load from the CPU but requires a separate processor on the card. A network card typically has a twisted pair, BNC, or AUI socket where the network cable is connected, and a few LEDs to inform the user of whether the network is active, and whether or not there is data being transmitted on it. The Network Cards are typically available in 10/100/1000 Mbit/s. This means they can support a transfer rate of 10 or 100 or 1000 Mbit/s.
What functionality is lost if the power connector from the CPU fan has only three pins?
PWM (pulse width modulation, which controls fan speed in order to reduce the overall noise in a system.
How many songs can be stored on a 500 gigabyte external hard drive?
According to Western Digital, you can fit up to 125,000 mp3s on a 500 GB drive.
It really depends on the file size of each song you have though. This varies depending on song quality and length and encoding.
What is software embedded into hardware?
Perhaps you're thinking of a BIOS or something like it? This is instruction written onto special chips that give directions on settings and variables to the OS.
How does a computer virus attack to your computer?
Computer viruses are mysterious and grab our attention. On the one hand, viruses show us how vulnerable we are. A properly engineered virus can have an amazing effect on the worldwide Internet. On the other hand, they show how sophisticated and interconnected human beings have become.
When you listen to the news, you hear about many different forms of electronic infection. The most common are:
Viruses - A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs).
E-mail viruses - An e-mail virus moves around in e-mail messages and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.
Worms - A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.
Trojan horses - A Trojan horse is simply a computer program. The program claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your HDD). Trojan horses have no way to replicate automatically.

Can you connect and use the CD-ROM on your PC to watch a movie on a television?
short answer: yes! you might have to buy a new video card and TV - but once you have the right hardware, you can make it work.
"not as short" answer: first, you need a computer with a CD-ROM... and of course the movie on a CD as well as the software to watch said movie.
second, you need a video card that that has a 'video out' and a TV with a 'video input'. connect the two using an rca cable - you can get one at any radio shack.
set your video card on your computer to use the video out and set your tv to show the video in.
turn up your computers volume!
you might have to reference the instructions that came with your tv or video card, but as long as you have the in and outs - it can work.
A byte is a standard "block" of data bits that was introduced by IBM and other manufacturers to store one "character" or "symbol" or some other standardized piece of data. A "bit" is the short name for a "binary digit" that can have only two values: 0 or 1.
1 byte is usually defined as 8 bits.
1024 bytes = 1 kilobyte
1024 kilobytes = 1 megabyte
1024 megabytes = 1 gigabyte Note:
All the above definitions have long been in common everyday usage within the computer industry.
Freezes could be anything from a virus to a bad piece of hardware. It could also be a particular computer program crashing in the background and grinding your computer to a hault.
What OS are you running?
What is the computer model?
What video card are you using? - a bad video card can cause this
Don't forget to look at the simplest devices like mice and keyboards. I had a bad keyboard that kept causing freezes. Replaced it and the problem vanished.
Does it simply lock up or do you get an error message?
How long has the computer been running before the freeze?
Although you say odd times, does the freeze occur after running a particular program?
Have you run a full virus and spyware scan?
There are just too many variables to determine what the culprit is. Before answering this question, you need to narrow down the characteristics of the problem for us.
I forgot to add, let me know the details and I'd be happy to try and help out on this issue. Freezes can be very frustrating and hard to diagnose. By replacing the power supply, you removed one of the big causes of freezeups. Now it's down to the strange and archane areas of computer tech support.
Is a USB stick an output device?
A USB drive is a device that stores data and could be considered either an output or input device, though not in the sense of a monitor or speakers being an output device or a keyboard and mouse an input device. The data it contains cannot be directly accessable by the human senses in those same terms.
soft copy is the type of output which is temporary.for eg:computer moniter screen
What are multimedia input device?
a multimedia input device is anything and manything ranging from video cameras, web cams, to ipods and flash drives it is basicly and thing that and store or transmit sound, pictures, or videos to another unit
How do you view a mini sd card on a PC?
You need a card reader. Some PC's have them built in; otherwise, you can buy an SD card reader that plugs into you USB port for about $10. Alternatively, you can put the card into a digital camera and connect the camera to your PC (requires the cord and software that came with the camera).
What must you do to change an inline graphic to a floating graphic?
apply text wrapping to the graphic
Which CPU is manufactured as a multi core processor with one of the cores disabled?
Triple
Edit:
"Triple?" What does this mean? Triple core? There are Rana processors that are shipped as dual-core but have 3 cores on the die. This means that your answer is wrong.
The most common examples are triple-core processors, but not all of them. As for actual examples, Phenom X2-X3 and Athlon X3 processors are famous for having locked cores.
How does a magnitude comparator work?
magnitude comparator is a logic circuit used to compare the two binary numbers in order to determine the relationship between those quantities.
Difference between 40x and 52x CD-r?
The short answer is that 48X and 52X, in terms of media, are really the same thing. The maximum speed of Recordable CDs, according to the Orange Book specifications, is 48X.
The recorder manufacturers are the ones that started marketing their recorders at 52X, this pushed media manufacturers to then market their media as 52X certified.
The reality is you cannot achieve 52X record speeds. The maximum burn speed that we've seen is 47.2X with a full CD. The write speed starts off around 16X to 20X and climbs to about 47X for a full 700Mb CD, and then drops a little during the finalization of the disc.
That's why review sites, like CDFreaks, talk about how long it takes to burn a full disc at 40X or 48X speeds. The combination of the media quality and burn speed influence the overall time to complete the burn. It would be great to have a burner recorder at 48X speed for any size CD because then we could easily figure out the time it will take. Unfortunately, that is not the case, the amount of information on the disc coupled with recorder and media brand contribute to the overall burn time.
And, now, most folks are purchasing combo DVD/CD recorders and these recorders are only certified to burn CDs at 48X or slower. The dedicated CD-R only recorders are going away - everybody is now using these combo DVD/CD recorders so this whole 52X vs. 48X is becoming less important.
How many pins does the enhanced ATX power connector to the motherboard have?
A regular ATX motherboard uses a single 20-pin P1 connector with optional 4-pin auxillary power connector
