1.How is a monitor’s screen size measured? It is measured diagonally across from one corner to the other.
2.Dot pitch is the distance between a dot and the closest dot of the same color (red, green or blue) on a color CRT.
3.Resolution is the degree of sharpness of a computer generated image measured by the number of dots per linear inch in a hard-copy, or the number of pixels across and down on a screen.
4.A Pixel is the smallest element of an image that can be individually processed.
5.CRT stands for cathode-ray tube. It is a vacuum tube in which a hot cathode emits electrons that are accelerated as a beam through a high voltage positive terminal, focused or deflected electro statically or electromagnetically to allow to show on a screen.
6.LCD means liquid-crystal display. It displays readings continuously on liquid crystal film sealed between glass plates that change optical properties when voltage is applied.
7.Plasma is a translucent greenish type of quartz.
8.DMA is direct memory access. It is a technique of transferring to and from external storage.
9.Solid state is transistor or crystal that can control current without moving parts, heated filaments, or vacuum gaps.
10.Clock cycle is the transition from 0 to 5 volts and back.
11.Serial port is a connector on a computer to which you can attach a serial line connected to peripherals that communicate using a serial protocol.
12.Parallel port is an interface in a computer system where data is transferred on more than one wire.
13.A PC card is a small removable circuit board that houses a device like a disk drive especially for laptops.
14.CD-R means Compact Disk Recordable. You can write information on it but cannot erase or modify it.
15.CD-RW stands for Compact Disk Rewritable. Data can be written multiple times.
16.Duty Cycle is the proportion of time of when a system or device is operated. It can be expressed as a percentage.
17.Kilobytes are about 1000 bytes.
18.Megabytes are about a million bytes.
19.Gigabytes are one billion bytes.
20.Terabytes are one trillion bytes.
21.USB (Universal Serial Bus) is a plug in interface connecting a computer and an add on device.
22.AGP (Accelerated Graphics Port) is an interface that enables 3-D graphics to display faster on ordinary personal computers.
23.System Bus connects the CPU to main memory on the motherboard.
24.PCI (Peripheral Component Interconnect) bus is an interconnection system between a microprocessor and hooked up devices where expansion slots are close for high-speed operation. Intel designed it.
25.ISA (Industry Standard Architecture) bus is a standard interconnection that allows 16 bits at a time to flow between the motherboard circuitry and an expansion slot card and its associated devices.
26.NiCd (Nickel Cadmium) is a type of rechargeable battery used for portable computers.
27.NiMH (Nickel Metal Hydride) are rechargeable lithium batteries.
They are all correct if that is what you are asking.

I am trying to compare these data storage types and get best storage ammount for cost.
Floppy discs, dvd-rw, cd- rw, Hard drives – 2.5” format, Hard drives - 3.5” format, SSD (Solid State Drives), Flash drives and Tapes, and wondered if anyone knows of a magazine article or table somewhere that shows this.
I am trying to compare the ammount of storage that you can get for your money - to say that you cannot compare them is nonsense, negative and pointless.
If you are just going to be dissmissive and glib you are not answering a question.
Well there’s tables for each one, not all of them. Just go to newegg.com, click at the top bar on computer hardware and it will give you a drop-down list. Select what you want (Hard Drives for instance) and you get a HUGE display of all they sell and the side bar lets you narrow it down. All PC components are listed in the drop-down menu. tigerdirect.com has a sidebar menu instead on the left.
Overall - can it host servers for games and other applications?
If Not - what is a good server i can buy
No, it’s a NAS, not a PC.
Edit: You’d need to buy a whole other PC to run the game servers you want.
One response so farOk this is the situation, i’m going start software engineering and network engineering however presently i do a bit of graphics as well, i’m thinking of upgrading my current computer setup and i need to store files and programs in a seperate machine for 1) Safety 2) Clearing up space on the working machine 3) Sharing, My question is, Should i buy a server or NAS? Can you also explain what makes the difference?
A server is a complete computer with shared drives or directories. An NAS is a drive (or drives) shared on the network with minimal additional firmware. You could always turn an old computer into an NAS by running FreeNAS (http://www.freenas.org/index.php?option=com_openwiki&Itemid=30&id=sug:en ) and adding a TB or ten of storage to it. That’s about the cheapest way. (Even a 5 year old computer is probably faster than your LAN if it has a Gigabyte NIC.)
We use both - NASs mainly for off-line storage (we have a few million tifs - if they’re more than a year old they go to a huge NAS), backup, etc. Files in daily use sit on servers. At home we have 2 large drives, each attached to a computer by USB, and they’re shared to the LAN.
For safety, all data is backed up to at least 2 flash drives whenever it’s changed. (Karen’s Replicator, and making sure the flash drives are plugged in, takes care of that. http://www.karenware.com/powertools/ptreplicator.asp )
2 responses so farI have XP on IDE drive and want to use new SATA drive for storage. After install it shows up in Device Manager as working properly, but ‘My Computer’ only shows c:\ drive. Is there a way I can get around re-installing windows just to get a raid controller?
Thanks. Formatting right now. Do I still need a raid controller though?
If its a brand new drive, you need for format it and assign it a drive letter before it will show up. You can do all that in Control Panel => Admin Tools => Computer Management.

IBM today unveiled new software that will enable businesses and governments to extract new business information from sensors to determine the whereabouts and conditions of millions of<strong> </strong>returnable shipping containers used to transport goods around the world. Using the software, massive amounts of sensor data can be gathered in real-time, providing supply chain transparency and reducing inventory costs by as much as 40 percent.
