Computer Hardware

Computer hardware is a general term used to refer to all the physical parts of a computer. Internal hardware devices include hard drives and motherboards, while external hardware devices include monitors, mice, keyboards, and printers.

Can you remove a Dell computer from a Dell docking station when power on?

For the Latitude C series laptops, the answer is no. You might succeed once or twice, but do it often enough, and you *will* screw up your computer.

Parts of computer hardware and their definitions?

Motherboard: a big circuit board where everything is connected.

Hard Drive: a form of digital storage where magnetic disk platters inside the drive (usually 2 or 3) spin at 5,400RPM, 7,000RPM or 10,000RPM (WD Velociraptor) and is constantly being written on and read by a magnetic drive head. They are connected to the motherboard via SATA (Serial Advanced Technology Attachment) cables. Older drives use IDE (Integrated Drive Electronics) cables.

CPU/Processor: A chip consisting of many electronic components (mainly transistors) and is connected to the motherboard. This is basically the brain of the whole computer.

RAM: Stands for Random Access Memory. Data is temporarily stored here to calculate things.

BIOS: Stands for Basic Input/Output System. This is a very basic chip which communicates with the software/OS to work.

Case: a box for the hardware to go in.

Graphics card: Is connected to your motherboard's PCIe or AGP slot. AGP is older.

Fans: cools various parts of the computer.

Optical drive: a laser reads CDs and DVDs in these drives. They spin the discs to read them. DVDs hold more than CDs.

What exactly does a motherboards rating 5338001066 MHz mean?

It depends on what it's referring to. It could be Front Side Bus, memory, or either bridge. You'll need to be more specific in what you're talking about. What it means by mhz is megahertz or million cycles per second (one hertz is 1 wavelength of ac electricity or basically one cycle). If it's your FSB, it's slow. (1066 MHz is 1.066 GHz and anything above that is standard today.) If it's memory speed, it's not that bad (at least the 1066 MHz isn't) but could be better. From the look of how you wrote it, it's probably the different speeds of RAM your computer can handle.

What is the difference between 2.66 dual core and 64bit dual core?

The difference between 2.66 dual core processor, and 64-bit dual core processor, is really two different processor specifications. 2.66 is actually 2.66Ghz, which is the clock speed of the processor. The clock speed tells you how many times the processor can execute instructions per second. A dual core processor is a processor with two cores on one die. This can be thought of as having two processors in one. The bit specification of a processor tells you how many binary instructions a processor can execute per clock cycle. Most processors today are 32-bit (32 binary instructions per clock cycle) or 64-bit (64 binary instructions per clock cycle). More RAM can be used with a 64-bit processor. A 32-bit processor is limited to addressing 4 Gigabytes of RAM, while a 64-bit process can address (theoretically) 16 Exabytes of RAM.

What are the advantages of Ethernet over Coax?

Using coax, you just do one long cable run, rather than with twisted pair where you do an individual run for each computer/terminal.

Problem? coax's max is 10 Mbit/s, and every computer has to take turns accessing the coax.

Using 10 Mbit/s twisted-pair, each computer has its own, dedicated connection to the hub/switch/router, so you're not slowed down when more than one comptuer wants access.

What are the pros and cons of a modular and non modular power supply?

Modular power supplies are generally far better then a non-modular, but there are a few drawbacks.

Pros.

Getting rid of the spaghetti kludge of cables coming of the back of older power supplies, many of which you may never use.

Only using the cables one needs reduces clutter and cleans up air flow inside a system which allows it to run cooler.

Modular power supplies are usually of a better quality and there for more reliable. NOT ALWAYS, check.

Cons.

I suppose a connection of cable rather then a straight path could increase resistance on the line and therefor cause more heat or a poorer electrical connection.

Loss of cables could be a major issue. Likely costly or difficult to replace.

Can you get your ip number from your computers model number?

NO an IP is assigned by a router or modem for determining the computer address for access to a network if you mean findinng out what your ip address is type whats my ip address in google

Computer not booting it is getting power as the lights are on and no beeps?

Process of elimination.

Something is keeping that computer from doing its job, some part of it is broken or has come loose, here is what you do to find out which.

Pull them out. One by one until it does beep, or gives you video.

So with the machine unplugged, open it up and unplug the hard drive. Now plug it in and give it a go. Still no video, no beeps? Well it wasn't the hard disk then. Unplug it and go in and plug the hard disk back in & try pulling out some RAM. Still no video no beeps? Put the RAM back in & try the video card.

Keep going this way, removing a piece, trying the computer, and putting it back in until you find some piece somewhere which makes it behave differently. Chances are at some point you will start getting video and/or beeps and you'll know who the culprit was.

What allows the processor to communicate with peripherals?

The key for any hardware piece to work with others is the SOFTWARE. That is why anything you buy for your computer (graphics cards, hard drives, etc.) it comes with software (or the driver) to help the computer recognize it and use it for the function its meant to be used for. I hope this is what you were looking for.

When you power up a computer by turning on the power on switch this is called a boot. If your computer is already on and you restart it this is called a boot?

If the computer is off the boot is called a cold boot or initial startup.

If the computer is on the boot is called a warm boot or restart.

What is the singnificance of CLIST in mainframes?

A "CLIST" could be thought of as a SCRIPT file for Windows machines. It's a set of instructions that are interpreted and executed when the CLIST is run.

What is an output device that uses a automatic manufacturing process?

An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form.

Where can I find forget password so I can click on it?

From the wording of your question I assume that you do not want the computer to remember the password for a specific web site any more. If that's the case, just clear the cookies.

What is a wireless world?

Its WI-Fi which is using internet without like computer or laptop for example people use Wi-Fi in phones,IPods,Pads,and Ect.

What is the main function of a traditional modem?

The main function of a traditional modem is to allow communications across different types of networks. This can include over phone lines, cable, or fiber optics.

What does someone add to image tags to enhance usability if they are using a graphical navigation system?

Alt tag would be very essential in this case and if backed up with title attribute it will enhance the usability more. The alt tag should be descriptive to the graphical element as alternative text to the image in case it was not rendered successfully or a delay occur; while the title attribute should be describing the image link in the navigation system.

Title attribute is very effective for search engines as its read as regular content. Using alt and title attributes are very beneficial for people with disabilities and increase keywords density for search engine as well.



The combination of both attributes in your navigation system shall increase it's usability if these two attributes were described professionally without any marketing jargon or abusing to their functionality.

What do you mean by an ideal computer?

computer is an electronic device capable of manipulating data so that useful information can be generated.

How many type of connector's used in computers?

  • USB
  • COM1 and COM2 (serial) Port
  • Parallel Port (for Printers)
  • Speaker
  • Mic
  • Video Port (Monitor Port)
  • Lan Port

Do usb condenser microphones need phantom power?

Unless they have a battery built in, if it's a pro condenser microphone with an XLR cable and it doesn't have a special funky power supply just for it, turn on the 48V phantom power. It won't work otherwise. Dynamic mics will ignore phantom power generally.
