Computer Hardware

non volatile memory is memory that doesn't wipe after the computer shuts down e.g: Flash memory.

for connecting 4 computers you would need a "hub"(en.wikipedia.org/wiki/Network_hub), and a cat5 cable to connect each computer to the "hub". each computer would also need a "network card"(en.wikipedia.org/wiki/Network_card), alot of modern computers come with a network card integrated so you may not need to purchase it separately.

Simply because the speed technology updates these days could leave your computer floundering with old components. In general it would be cheaper to upgrade things like the RAM, hard-drive or video card. However - if you needed to upgrade lots of components, it's likely to be cheaper to buy a new machine.

The voltage which charges the capacitor can only hold peak voltage. It can only use the energy stored in the capacitor if it uses faster than the power supply can replenish it causes a ripple.

Some of the advantages of RAID O is that it is a very simple design, it's easy to implement, I/O performance is greatly improved and the data is broken down into blocks which means each block is written to a separate disk drive.

Heat sinks are very important components in computers. The purpose of heat sinks in computers is to keep the computer from overheating. The heat sink removes heat from the processor, keeping the processor cool.

10 GB = 1024 x 10 Megabytes

10240 Megabytes = 10240 x 1024 KB = 10485760

Yes you can.

They will work fine. These statements "they are not designed to do this and would not do it well" WRONG and "Performance would be terrible and the drives would fail much sooner" also WRONG. U320 drives are backwards compatible and should work without issue on a U160 controller, the performance will be the same as a U160 drive and will not affect the drive's MTBF.

The drives will work fine !! The performance of the drives is NOT impacted at all --> they still rotate at the same speed; the seek times aren't any different; etc. The ONLY difference is that the interface speed is different (Ultra 160 vs Ultra 320). ... and it certainly has NO impact on the reliability of the drives !! [r.e. "... the drives would fail much sooner ..."].

... in fact, unless you're using an array which could support a sustained transfer rate higher than Ultra 160 speeds, the ONLY time there would be any difference in performance (compared to an Ultra 320 controller) will be in transfers to/from the drive's buffers => a very low % of disk operations.

Bottom line: Buy the disks you listed. They'll work just fine :-)

Long long time ago a character was only one byte. Now (unicode) a character is 2 or 4 bytes, but usually we use a variable-length encoding called utf-8.

A sheltered port is a harbor.

P1 motherboards are "Socket 7", it should be written on the CPU socket. Also, they only have PCI and ISA expansion slots, AGP and PCI-E Video cards slots never appear on a P1 motherboard. The ram slots may be either 72-pin or 168-pin 'Dimm' slots (on desktop motehrboards, laptop boars could have either of these or 144-pin So-Dimm.

A lot! Honestly, with some good quality, anywhere from 2,500-10,000

RS232 is for point to point communication where as RS 485 is for multidpoint communication, Voltage level and speed differ

Hi frnds,,

There are few points which v can discuss on these are

1) Ya first main important point is RS232 is point to point communication n RS485 is multidrope communication which means ...

on RS232 u can not connect more than two device...

RS485 u can connect upto I think max 128 device theorically..(its depends on noise level as well as on distance and burd rate also)

Practicall as max 32...

2)Voltage level of RS232 is

-3 to -25 for 1

+3 to +25V for 0

while RS485 is based on differential voltage (0-5v) diff is 240mV for 1 and -240mV for 0.

3)distance limitation is 100meter for RS232 and 1Km for RS485,

4)noise immunity is high for RS485 as it is balance protocol and differencial protocol..

5)Software point of view u need to set transmit enable line in RS485 rest of the software is same...

6)pin for 232 is (Rx Tx and GND) while in case of RS485 it is (A(+) and B(-)) no need to transmit GND..signal

Since you were able to ask that question on the Internet I am assuming you already have access. If you want to hook up a wireless network then you need a router and a wireless network card in your system. The cable that you currently have to get on the internet will go into the router then another cable will come out of the router to the internet. The router will come with software for you to load. It is really not as hard a process as people think. You will set up a password on your wireless internet so only the people you want to get on it will be able to.

A heat sink works on the principle of thermal transfer.

The heat sink transfers heat from the chip to the air, wicking heat away.

Is known as the socket. This is embedded in and wired to the motherboard. The socket provides various currents for different parts of the processor and allows the transfer of data to and from the CPU. Different processors use different socket design, as some require different power phases and data pipelines.

It is a number used in a certain format simply to let network aware applications differ one service to the other. Common syntax is : url:logical port number.

example :

80 - http service

The visual output seen on a computer screen. The audio output heard from a computer's speakers.

Some systems still have a dedicated audio card, this is that makes the outputs for sound work.

These days most computers don't have specific specific audio cards, most motherboards (even cheap ones) are sophisticated enough to offer Dolby 5.1 via an optical SPDIF socket. So there's no need for an audio card.

It's a storage device.

from what I've seen, there are many different types of coaxial cables and they all have different transmission rates. From the old days, (90's), TV had a transmission rate of about 768kbits/s, which is now irrelevant because there are cables that can go up to 200Mbits/s (According to what I have gathered here)

It all depends on your motherboard and case. I can have 8 drives in my case, but with my motherboard I can only have 8 SATA connections. So if you want an optical drive you have to sacrifice a HDD. However with HDD's being as cheap as they are you shouldn't need too many.

It varies from computer to computer.. It's sometimes infrared and sometimes iron sight.

Drivers. Drivers is like a middle-ground between software and hardware. It takes input from software and translates them into instructions the hardware can understand.

Firmware is the software that the hardware is already programmed. Firmware is what allows hardware to "think" for itself.
