The Difference Between

Both of these forms of communication are a means of transmitting data. The difference is in the format that the data is transmitted.

Asynchronous communications is the method of communications most widely used for PC communication and is commonly used for e-mail applications, Internet access, and asynchronous PC-to-PC communications. Through asynchronous communications, data is transmitted one byte at a time with each byte containing one start bit, eight data bits, and one stop bit, thus yielding a total of ten bits. With asynchronous communications, there is a high amount of overhead because every byte sent contains two extra bits (the start and stop bits) and therefore a substantial loss of performance.

Synchronous communications is the more efficient method of communications. CQ's connectivity solutions communicate through the synchronous method of communications.

Through synchronous communications, data is transmitted as frames of large data blocks rather than bulky individual bytes. One advantage of synchronous is that control information is easily inserted at the beginning and end of each block to ensure constant timing, or synchronization. Another advantage of synchronous is that it is more efficient than asynchronous. For example, a 56 Kbps dial-up synchronous line can carry 7000 bytes per second (56000/8) compared to a 56 Kbps dial-up asynchronous line which can only carry 5600 bytes per second (56000/10). When transmitting large amounts of information, this translates into a significant increase in speed and performance.

To see this work you can work out the efficiency rates and time that it takes to send each message

Asynchronous would be worked out as follows

To get the efficiency of it you

get assuming the message is being send over a 100mb line and 70 bytes to send and 300 characters

then it is

70*8 = 560 (the 8 is for the 8 bits to make up each byte)

the 70*2 (the start and stop bit) =140

= 700

then to

get 560*100/700= 80

that means that 80% efficient

To get the time

Asynchronous

300 *(1+7+1+1) =3000

take this and divide it by the size of the line in this case 100mb

so that is then

3000/100=30

that means that it would take 30 seconds to send

for

synchronous efficiency

Then

70*8= 560

then 4 bytes = 4*8 (the over head bits) = 32

560+32=592

560*100/592=94.5

then that's 94.5% efficient

and for the time then it is just

300+4*8=2342/100=23.42

that's then 23.42 seconds

this shows you which is faster and more efficient in each case

240 used 133MHz SDRAM memory, max 1GB - 2 slots. No SATA. 100MHz bus and USB 1.0

270 uses PC2700 or PC3200 (333 or 400MHz DDR), max 4GB - 4 slots (only 2 if SFF), has SATA, 8xAGP, and USB 2.0

3 Ways are much better, but it depends on what you are after. Stock car, stock speaker holes, 3 ways are better. Totally custom, multiple speaker holes, 1 or 2 ways are better.

reason being. as far as sound and music you have 3 dimensions High Low and Mid, a 3 way wraps all 3 into 1 self contains speaker, but its tightly contained, tiny tweeters, and not much bass.

If you have the space to play a 1 way is best. because you have a speaker that is designed for each signal. subs for your bass, and tweeters for your high voice and instruments, and your mids to bring them both together. if everything is separated you can aim your sounds where you want them, like tweeters, subs don't really matter that's why they are typically in the trunk and not mounted under the seats. so if you are just updating the speakers in you car just go three way, they are easy to install and typically replace your stockers fairly easy, instead of adding a bunch of other stuff to your car. I typically do 4 3 ways, 2 front 2 in the rear deck under the glass, and a single sub in the trunk(like a 10), and no amp. if I put an amp its a 4 channel and its going to my 3ways, and my sub will probably be taken out. it depends on what brand you're using, sony-ok pioneer-better, the German stuff like blaukpunct or Bose- much better, it just depends on the sound you are looking for. I rather hear the voices over the bass. so it sounds like the artist is sitting right next to you.

and obviously the more expensive the speaker, the better it will sound.

Internet with capital 'I' refers to the Internet as in the world wide web, and what most people think of when you say internet.

Internet with a lowercase 'i' refers to a bunch of small LANS connected together to form some kind of host-to-host packet delivery service. So basically Internet capital I refers to inter-networking at the global level. Whereas internet with a lowercase 'i' refers to it on a much smaller level.

.org stand for organisation

.com is comercial Above is the begining idea. Now .com is KING. It for everythings Wikipedia is your friend:

.org was one of the original top-level domains, established in January 1985, originally intended for use by organizations that did not meet the requirements for other gTLDs. Now anyone can register a .org domain. .org was the domain commonly recommended for use by individuals, although .name and .info are now alternatives. From http://en.wikipedia.org/wiki/.org

See also http://en.wikipedia.org/wiki/.com

Functionally, there is no difference, and as both are unrestricted either can be used for anything the owner chooses, although .com is by far the more popular.

3G is the current generation of mobile telecommunication standards. It allows simultaneous use of speech and data services and offers data rates of up to 14 Mbps downlink and 5 Mbps uplink.

4G is the fourth and the next generation of mobile telecommunication standards. Its infrastructure will be only packet-based (all-IP). 4G will probably combine 3G, GSM, Wi-Fi, Bluetooth, and VoIP.

There is no difference between LAN and Ethernet cables. These cables are used to relay internet service to electronic devices equipped to utilize the internet service.

0.25 litres is 250 millilitres, 25 millilitres = 0.025 litres.

In the 8085 microprocessor, the MOV instruction copies data between two registers, or between a register and memory. The MVI instruction differs only in that the source data is contained in the byte immediately following the opcode byte.

From Bose 10/25/2011: The AWRCC1 is Graphite Black, the AWRCC2 is White. That's the ONLY difference! The last digit or letter tends to represent the color. The rest refer to the model and features.

Norton Antivirus is Symantec's full version antivirus program. Norton Security Scan is offered by Symantec & Google and is a free version of Norton's popular antivirus, however, it does not include real-time scanning. Norton Security Scan does receive free Virus Definition updates and will scan & remove any existing viruses on your computer, however, you still will not have any real-time protection.

89S52 have 8KB ROM and 256bytes RAM also it supports SPI program downloading but 89C51 have 4Kb ROM, 128bytes RAM and it wont support Serial program downloading.

An email is a text document which is sent to your Internet Service Provider server when you press the 'send' button. There it sits for a little while, from a few microseconds to an hour or so, whenever the mail server batch process outgoing email. This document is transmitted as a single file, including attachments, to another server, the recipients Internet Service Provider incoming mail server, by way of servers which forward all mail to the closest address available. The message then resides on the incoming server until downloaded by the recipient.

Instant text messaging is a series of data packets, sent as the 'send' key is activated, which are routed which ever way is available, to another computer. However, many ISP text servers are operated in a batch processing fashion, so the text messages may sit in the outgoing server for a second or two.

On line chat is a conversation between two or more people at computer keyboards, which is made up of data packets sent for every line, return key press, or other interrupt, and without delay, to each computer that is logged into the chat session. So, each packet that a computer sends out might be cloned into several hundred packets, to allow all the logged on users, even the 'lurkers', to receive a person's words.

Email is fast, text messaging is faster, and on-line chat is fastest.

This is quite a complicated question! In many ways, Vista is an improvement - DVDs are handled much better (XP doesn't really understand writing DVDs), navigation in explorer is better, finding applications is easier, multiple screen handling is better, wireless networking is better, finding applications is much quicker - press start and type the name and the application you want will pop-up instantly. With all these (and other) improvements, there is little that compels one to use Vista over XP; this is quite common with newer operating systems. When XP was released, it was a year or two before "killer" applications were released that were XP only (Photoshop CS was one such). Against Vista is the hardware requirements; 1 Gigabyte is too small to use comfortably. This is generally the case, XPs hardware requirement is much greater than Windows 98.

Mains supply provides alternative current while battery provides direct current.

lcd coz in sunlight amoled is useless.......super amoled is best of two.

TFT (Thin Film Transistor) which is a type of display technology for LCD has better sunlight visibility than AMOLED. However, Super-AMOLED (which is lot better than AMOLED) comes to very close to LCD in terms of sunlight visibility.

Television advertising has proven to be highly substantial for a number of reasons. One of the main ones being that you can't "X" out a television Ad. You can switch you're TV to a new channel, but there still remains the chance that a commercial could be playing on that channel as well. The internet makes it much more accesible to get rid of and ignore ads than TV. While you might channel surf, the likeliness of you turning off the tube to avoid advertisement is extremely rare. Another factor is the volume of ads. Typically on webpages you're presented with an ad or two, usually heading or drawing up the side of the page with the ocassional pop up. With TV, commercials are on literally every few minutes. TV can reach audiences on a more interactive, personal level. They show numerous scenarios of people engaged in every day life and activites, giving the viewer something to relate too. Internet lacks this appeal, and its advertising suffer because of it. These obvious advantages give TV a much higher edge when it comes to advertising.

But as technology grows, people can fast forward through commercials with the new DVRS. If the internet somehow comes up with a better marketing campaign, it might just flip around sooner than expected.

There are quite some differences between an optical mouse and a laser mouse.

One of the most noticeable differences is the type of rays coming out of the mouse. Now,we all know that from an optical mouse there is (usually) a red light coming out and on the other hand, the laser mouse does not produce such light. It produces an invisible laser beam which is harmless to humans.

Also,they say,that laser mouses are much more precise than the previous generation mouses, 'thus making them much more valuable.

And finally, you can use laser mouses on almost all surfaces (except glass, mirrors and air) which is quite useful in many situations.

Of course,there are many people questioning which is better - the laser mouse or the optical mouse,but one thing is for certain - they may look the same,but they are definitely not the same thing.

Answer: Unlike Plasma TV screens DLP and LCD last much are longer, and are considered to both have superior image quality. LCD screens tend to have slightly better contrast, with a larger range of black and white color shades. DLP, however, still has faster refresh rates than LCD (although LCD has been vastly improved in this area over the last two years). This can have implications if you are really into high-action motion (sports, action movies), because movement may seem a little blurred with LCD at times. Also, you'll want to remember that in order for you to get the best color out of your LCD, you have to sit right in front of it. LCD TVs also have a slightly shorter lifespan than DLPs, with only 45,000 to 60,000 hours compared to 75,000 hours or more. As far as price goes, LCD and DLP are still more expensive than Plasma, but like all things in time, their price has been coming down. And right now, DLP is slightly more expensive than LCD, but not by much. DLP, in our eyes, is the best investment, at least for the next few years.

The biggest difference is that DLP is a projection technology. Most TVs do not use projection screens.

Yes: Desktops have standardardized formfactors for their peripherals whereas laptops have different formfacters for each company. Also, the components are larger, there is more room for new components within the case, and more expansion ports in a desktop computer.

As for Segmentation in Computer Architecture logic, it's a meaningful unit of information eg procedures, large data structures etc. In segmentation every segment is in its own logical memory. # it has higher hit ratio # meaningful protection of segments # simplified sharing of code via dynamic linking # dynamic data structures OR Segmentation is one of the most common ways to achieve memory-protection; another common one is paging. Segmentation means that a part or parts of the memory will be sealed off from the currently running process computing, through the use of hardware-register. If the data that is about to be read or written to be outside the permitted address-space of that process, a segmentation-fault will result. Segmentation is a memory-management scheme that supports this user view of memory. A logical address space is actually a collection of segments. Each segment has a name and a length. The address specifies both the segment name and the offset within the segment. The user therefore specifies each address by 2 parameter: a segment name and an offset.

A simple machine performs a task using energy. Is does so in a fully automated fashion. A mechanism is mechanical, and often requires input from the user.

There are more than two types of user interface.

There is a mouse

a keyboard

voice command

gesture command
