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.

What are three advantages to serial ATA installation?
In asking this I can safely assume that you have at least a rudimentary understanding of the workings of a computer.
Serial ATA (more commonly referred to as SATA, or the newer SATA2 standard) is a new standard connection for computer storage devices such as hard drives and DVD drives, that replaces the older IDE system of connection.
SATA holds a few advantages over IDE, the first and most important of which is speed. SATA devices have a faster data transfer rate than IDE had. SATA 2 is twice as fast as SATA.
SATA devices use a new connection method. Gone are the old IDE Ribbon cables, and molex plugs, SATA now has some much thinner and smaller data and power cables. Because the plugs are physically a lot smaller, it means more sockets for SATA data points can be fitted onto a motherboard.
Because the cabling is much simpler going straight from the motherboard to the drive, the need to set individual drives to be slave or master drive has gone, which means no more messing with small fiddly jumpers!
One of the great benefits is that SATA devices ate "hot swappable", which means even if a drive is powered up, it can still be unplugged and removed, and you can plug SATA drives into powered up systems with no adverse effects. This is great if you run multiple drives in an array or raid.
Finally the cost is usually cheaper than a comparable IDE device these days.
State 4 forms of output and four types of output devices?

Can you install an operating system to an external hard drive and install it internally afterward?
yes you can and i know because i did it this will only work if your computer supports SATA drives 1. buy a vantec external hard drive 2. use the SATA plug that comes with it to plug it in 3. restart your computer to enter the setup 4. install onto your hard drive CAUTION make sure you dont overwrite your computer hard drive then your done you can then remove the HD from the case with a screwdriver and install it into your computer
How is a computer's date and time updated without power?
Most computers have a small battery that lasts for a period of time, even if not plugged in. That power source is used for a number of items, including updating your date and time stamp.
How to add more memory to a 2 yr.old computer?
Depends on whether you mean storage space or RAM. For storage space: Buy either an internal or external hard drive.
Install onto your computer
Save files to it. For more RAM Find out the type of RAM currently in your PC (Often shown on the ram sticks themselves)
Buy a set of RAM sticks of a larger memory size, making sure its the same type as in step one.
Either take out old RAM and clip in new, or if spare sockets available leave old RAM in and install new as well.
Does a computer power cord plugged into the wall but not the computer use electricity?
No, if it is a desktop power cord - which is no more than a few wires (no internal components). Yes, if you're talking about a laptop - most laptop power cords have a LED built in that will take power, beyond the necessary "no load" power used by the step down transformer and DC rectifying circuit.
If you only have one audio output port then you are stuck.
Most modern motherboards have 6 audio output ports. It's actually called 5.1, with the sub-woofer the .1 port. So you get front left and right, rear left and right, center, and the sub-woofer port.
If you only have 1 port then you need to get a 2.1 speaker system.
A modem is used to connect a computer to the telephone. This was traditionally used a lot as an Internet connection, although currently it is getting more common to use other technologies, like ADSL.
Where would you place components of a computer when trying to repair a computer?
It depends which component you are trying to replace, but almost all of the components are installed upon the motherboard, the CPU often below the heatsink (fan); the ram is in sticks and the psu is at the back, off the motherboard.
Is a server an end device or an intermediary device?
A server Is an end device.
A server, is innately is either a source or destination device, which is, by definition an end device
Where can you buy a Foxconn motherboard?
One can purchase a Foxconn motherboard online at a variety of different websites. One can purchase a Foxconn motherboard at websites such as Amazon and eBay.
Why iPhone not charging in usb port of kia cerato coup?
Your iPhone is not charging in USB port of Kia Cerato Coup because the USB port is faulty.
Given a page size of 2M and 1G of virtual memory, the minimum size of an entry in the process page table is 11 bits, excluding status flags, and there will be 2,048 (64K) entries in the process page table, but see the discussion below for other, probably more useful answers.
The answer depends on the size of physical memory, and on whether or not the page table requires a full base address or not. First of all, a page size of 2mb is not standard - a typical page is 1K to 4K, 4K being using in the Intel processors, but this answer assumes a 2mb page size.
Lets assume the base address in the page table does not require a full base address - a usual configuration. That means the base address is 11 bits. (232 = 1,073,741,824 = 1G. 221 = 2,097,152 = 2M. 32 - 21 = 11) That means the base table field is 11 bits (211 = 2048. However, page table entries are usually rounded up to the nearest byte, 16 bits, so 216 = 65,536 = 64K. This also give room for status and access control bits.
However, the question did not specify the size of physical memory, so the above answer assumed the virtual memory was the same as physical memory, not a usual configuration.
Lets assume a 64GB physical memory size, since you seem to be talking about very large processors. 236 = 68,719,476,736 = 64T. 215 = 32,767 = 32K. 36 - 21 = 15. 15 bits per entry, rounded up to the nearest byte, is still 64K bytes, so we are still talking about 64K.
Although your question did not include status bits, and 1 bit is not enough for a reasonable implementation, and most architectures also use a factor of 2 for their hardware page table, in order to minimize complexity, so we are talking about 128K.
Last, you asked "minimum size". Most processor include a length attribute to the page table, so 64K (128K) is the maximum, and it could be smaller, depending on actual virtual pool size.
Port 447 is assigned to the service:

Which are the random access devices?
In reference to your PC; RAM, CD, DVD, Floppy Disks, Hard Disk Drives, Flash Drives...
Any device from which you can retrieve the last byte stored at any time without having to read any other data stored prior to it.
Tape Drives are not Random Access. In order to reach the last byte stored on the tape, you must read all the bytes stored before it.
Will Ati Radeon HD 5770 work on Optiplex 745?
Yep, that should be working fine. Just connect the 5770 to a PCI slot on the motherboard, and connect the power PCI power cable from the graphics card to the PSU (Power Supply Unit).
Who are the hosts of the Stuff you should know podcast?
Chuck (Charles) Bryant and Josh Clark. This is my favorite podcast!!!
This is a ratio question.
Simply put, both new sides will remain in proportion to each other.
To find the new length of a side,
new length divided by old length multiplied by old width = new width
i.e. 7/11 x 8.5 = 5.4 inches
What colour pen should you write in for the best memory results?
In my opinion, it would be red. i would say black so that you could not flip right pass it without seeing it
How is black edition amd processors different form other amd processors?
AMD BE or Black Edition CPU's are exactly the same as the non-BE version with one difference. Black Edition CPU's have a unlocked multiplier allowing for easier overclocking, IE clocking a 3.2 ghz CPU to run at 3.8ghz for example.
