Computer Hardware

If the computer is recently purchased, look for an "EnergyStar" in the manual, or during the bootscreen of the computer. This ensures that the computer consumes a low amount of energy when compared to the possible amount of energy any given computer can consume.

Also, in the manual look for the RoHS symbol, this company's acronym stands for "the restriction of the use of certain hazardous substances in electrical and electronic equipment".

No you can not plug a PCI card into a PCI-Express slot. PCI and PCI-Express slots are physically of different size and differ in connectivity. - Neeraj Sharma True, you cannot directly connect a PCI card to a PCI Express slot, partly because the physical slot design is different, but also because PCI and PCI Express handle data in completely different manners. There are however, adapters available that will enable you to connect a PCI card to a PCI Express slot through an interface that "translates" PCI signals to signals that PCI Express can read. They are available in single PCI to PCIe configurations, but those require a bit of extra space within the chassis if your computer. You need to make sure you have the required space available. There are also adapters available that include a PCIe card with a serial(?) port to which you connect a cable that attaches to an expansion box that accepts multiple PCI cards. One example can be found here:

Of course, you should remember that using one of these means you are pumping four PCI card's worth of information through a single PCIe slot. You need to do your homework before just randomly plugging four cards into an adapter like that. A combination of Firewire and USB cards may not be a problem, whereas combining video and sound cards could present problems. Due diligence is certainly called for! For a better understanding of my edit to this answer, you may want to read the discussion area.

The biggest disadvantage is the same with any removable data storage, that it might get lost. But more than that pen drives have relatively small storage capacity. They hold out better against CD's because they are re-writable but still, in the end it actually depends on you, the purpose and if you prefer the portability of pen drives over other storage options, like an external hard drive. Or if you chose pen drives over cloud storage because you don't always have access to the internet

Yes, it is possible to protect your hard drive using the lock command. E.g.

Lock sys: on - this will lock your partition Lock sys: off - this will unlock it.

If you wish to lock a drive other than your main partition simply substitute Sys: for the drive name.

I have a question for you: How do you turn ON write protection on your hard drive to begin with? As far as I know you can't. Hard drives were designed to be written on. You can't install an operating system on it without writing to the disk.

The only way to prevent someone from saving something would be through the operating system's security management. Before you can disable what you think is write protection, you need to understand what is protecting it to begin with.

Simple! Click Start Button > Type: Create and format hard disk partitions > Enter > Right click on your drive (the one that's write protected) > Click Offline > Right click again > Click Online. Voila! tnt4real!

Some hard drives have a jumper on them for write protect. You need to check the jumper settings

I just had this issue with one of my external hard drives. It's an internal drive that I installed into an external case and connects to my computer via FireWire. I knew it couldn't be a jumper setting, because the drive has not been removed from the case since it was put in there. I did NOT turn "ON" write protection at any time. I've been writing to this disc with no problems (daily) up until today. I tried copying a file to it, it popped up a message saying that can not write to disk, disk is write protected. I did nothing to cause this. No settings, attributes, etc. After looking around a bit with no luck (not even from here). I tried a couple of my own things. Found I could not change attributes (cause disk is write protected).

I finally unplugged the drive from the firewire port and waited a few minutes. Plugged it back in and let the computer "find" the drive again, and all is well.

The write protect is in your bios. You select "enable" write protect and it will ask you for a password. Note: not all bios versions offer this option.

I'm considering cleaning up my hard drive of all unwanted ware, especially spyware, and then turning on "write protect" for my hard drive to keep the stuff out. I'll be using a flash pen to surf with which can be cleaned much faster than a hard drive full of stuff and zillions of places for things to hide.

The post above said you turn on this feature in the bios. Can you elaborate on this as to how it's done? I have a Thinkpad r40 and can't seem to find anything on how to do it at ibm or google.

Thanks in advance...

I just had the same thing happen. Hard drive said write protected. Not even a floppy at boot would work. Then I realized when I hit delete for setup, both the hard drive and floppy were flipped to write protect in the bios.

I had the same thing happen to an old P III 800mhz computer; "write protected" message. After reading this I looked in CMOS for a setting for hard drive write protect, I have never heard of this as a bios option (floppy write protect yes, but not harddrive), did NOT find a setting for write protect for either floppy or hard, but I went ahead and did a reset CMOS to optimal setting anyway, booted and all was right with the world!

Thank you for the helpful info. I had tried everything, including fdisk/MBR, cloning to new hard drive, trying to do new install of OS on fresh drive... all failed, thought motherboard or IDE subsystem was hosed. Resetting CMOS WORKED.

If you download Windows SteadyState you have the option to limit who has access to what. You also have the option to lock your HDD. Everything you save will be undone the next time you boot. Here is the link to the download for you.

Just copy and paste that website into your browser. Also this is made by Microsoft and is free.

A game console is not an input or output device, the things that can connect to the consoles are the I/O devices.. not the actual system.

There is a type of DVD called DVD-RAM. It is rewritable, and supports up to 100,000 rewrites, as opposed to 1,000, for the +rw, and -rw standard. It also has greater error correction ability. DVD-RAM can act like a slow hard drive, in that you can write files directly to the disk, as well as delete individual files.

I myself have not seen many DVD drives that support DVD-ram, most likely because the media is expensive, not widley avalible, and exceeds the need of the average user.

FireWire (technically known as an IEEE 1394 interface), introduced by Apple in 1995, allows a fast connection for peripherals such as video cameras. It is similar to a USB connector. The original version is now known as FireWire 400. FireWire 800 was introduced to give faster transfer speeds and supporting longer cable lengths without loss of signal. The connectors for the 400 and 800 versions are not interchangeable but converters are available which will allow FireWire 400 equipment to be connected to the FireWire 800 port at the slower connection speed.

Yes. Go in to your 'start' menu by clicking 'start,' bottom left; click 'connect to,' and choose how you want to connect--wirelessly, or with a cord for better throughput. For wireless, you can alternately go to the icons at the bottom right of your desktop and click or Rclick on the wireless icon there for options like 'connect' and others, which will then ask you to choose a wireless signal from a list.

In the worst case, your wireless program is not turned on, and you should have an option for this in Rclick.

The most recent HughesNet actress (as of late 2009) is Kimberley Joseph.

She was also in Cold Feet and also made some appearances in Lost.

Unfortunately, many organizations are controlled by the financial world and somehow those people seem to think that everyone should be using Microsoft products.

The reality is, most varieties of UNIX provide more flexibility and power for real-time applications, as well as low level controls.

Information in the BIOS (Basic Input Output System) includes things such as power settings, installed memory, hardware details, clock settings, Access to various functions such as "wake on LAN". The initial function of the BIOS is to identify, test, and initialize system devices such as the video display card, hard disk, floppy disk and other hardware. This is to prepare the machine into a known state, so that software stored on compatible media can be loaded, executed, and given control of the PC

Computer input devices are anything that allows a user to control a computer or inputs information into a computer. These devices may include your mouse, keyboard, or gaming controller. They may also include devices such as your microphone or camera.

You do get a slightly faster connection with Ethernet over USB. This can range from 1% to 5%. The main advantage is not necessarily speed but stability. Ethernet is a much more stable connection. I highly recommend connecting via Ethernet. If your computer does not have an ethernet connection, you can purchase a card for around $20 and install it.

It doesn't matter when dealing with a residential broadband connection. USB is around 11mbps and your internet is anywhere up to 3mbps. Its all a matter of what hardware you have to utilize.

I prefer cat-5.

Neither. A computer contains both input and output devices. Many modern input and output devices contain embedded computers, that interface between the main computer and the actual input or output hardware of the device.

Inventory management is a critical component of many businesses and having the right equipment and software can make or break the job. The materials required to track inventory can include computers, UPC scanners, radio frequency identification tags and other wireless methods for tracking. Another important component needed is an IT person to train employees in how to use the software.

It depends on what kind of motherboard you're talking about. Generally speaking there are AMD based motherboards which will be used with AMD processors, and there are Intel motherboards that are to be used with Intel processors. For example, Asus is a motherboard manufacturer which offers both AMD as well as Intel motherboards. All other motherboard manufacturers usually offer both Intel & AMD.

A CD will store 700MB of data

It all depends on the type of disk

IDE stands for Integrated Drive Electronics - It's a type of interface to connect IDE hard drives to the motherboard. IDE connections use the wide gray 40/80pin cables.

IDE connections are being replaced by the faster SATA (Serial Advanced Technology Attachment) which has a smaller 7pin cable and can hot swapped as well.

That is called a Local Area Network (or LAN for short)

It is wired internet, it uses just a basic cable to give computers internet connections if they have what is called an Ethernet port. It is also generally faster than Wi-Fi or 3G which are a couple wireless forms of internet.

Plotter is a special type of printer used to print graphical output on paper. It interprets computer commands and makes line drawings on paper using multicolored automated pen. The potter is capable of producing graphs, drawing, charts, maps, illustrations etc.
