Differences of communication system in the past and present?
4/17/2010 By: Insha
In the past there was communication devices that we now do not have. In the past there were such things as smoke signals, telegraphs, carrier pigeons, animal sounds and early telephones. plus letters. In the present we have cell phones, telephones, email addresses, fax machines, and more. so that's the differences of the communication system in the past and today the presents of the 21st centuries.
Where can one find out more about an information technology job?
There are various ways to find out more about an information technology job. First of all, think about your direct environment. You probably have an interest in an information technology job for a specific reason. Maybe you know someone in the field? A good way to start is to ask someone like that. This could be a friend, relative or teacher. Such a person might just give you the information that you are looking for. Another way is by reading articles about the field. This could be in magazines and on the internet.

What are the forces used in roller coasters and how do they work?
I always love these questions! When you are on a roller coaster, there are a few things you should realize when it comes to the force. First, is that you start out at rest. This is a good start because we can measure the differences in force from this point. Next, you probably will climb a hill. This creates what is call "gravitational potential energy" (GPE). Next, you hit the top of the hill. This is where your cart will have the most GPE. Next, you go down the hill which transfers the GPE into kinetic energy. The kinetic energy is what moves the cart around the track. If you were to look around at the top of the hill, you may notice this is the highest point of the ride. This is because more energy will have to be given to the cart for it to get up that hill. That would just cost more so it is left out. Those are the main forces that apply during a roller coaster. There is also excess energy given off from friction, sound and from air resistance but it does not really affect the ride. If you have more questions, ask on my profile page.
What channels do you get with a digital converter box if you have no cable?
If you have no cable service you will not get any stations. You will have to get an external antenna and get over the air broadcasts. If you attempt to get cable without service that is a violation of federal law and you can get prison time and a huge fine, be careful.
You should get the major news channels, i.e, CBS, ABC, NBC, etc. Also, the CW, any PBS channels and maybe a couple of other local channels.
Difference between primary server and secondary server?
Primary Means, it is individual there is no dependence, But Secondary will allays depends on Primary, If you want to do Secondary, you should complete primary first, There is no precondition to primary, but for Secondary Primary is the Precondition, first you should do primary, then only you are able to do secondary.
The Electronic Communications Privacy Act (ECPA) of 1986 aims to protect the privacy of electronic communications by prohibiting unauthorized interception or eavesdropping by individuals, businesses, and government entities. It covers various forms of electronic communication, including telephone calls, emails, and other digital transmissions. While it establishes certain protections, there are exceptions, particularly for law enforcement under specific circumstances, allowing them to access communications with appropriate legal processes. Overall, the ECPA seeks to balance privacy rights with the needs of law enforcement and national security.
What carrier offers BT Broadband?

How high do GPS satellites orbit?
24 -Physics for Science and Engineers Tipler and Mosca Page 84
answ2. A constellation of satellites is usually 24 plus a few spares to allow for mishaps.
There is the Navstar GPS set, there is a Russian named Glonass, The Chinese are well through completing their set, and the European Union has made a start on Galileo.
From all of these one may obtain GPS data, and all operate in closely similar manners and frequencies for rather obvious inter-operability reasons.
What tool should be used if a user needs to optimize space on a hard drive?
If you are on Windows XP then use Disk Defragmentor and Disk Cleanup which can both be find in the Start Menu under-- Start -> All Programs -> Accesories -> System Tools. You can also check out programs on the web like a registry cleaner. Registry cleaners are very effective when it comes to speeding up your computer and fixing common errors.
What is the code for the safe in Final Fantasy vii crisis core?
the code is different for each game.
There are 4 rooms that are locked, but you can look into the peepholes.
In each room, you have to count something and jot down the number.
1) On the top level, go to the room with the books and count all the books
that are NOT on the shelf. This includes the books on top of the case.
2) On the bottom level is a room with floating pumpkins, count those.
3) Also on the top level is a room with apples and cans. Count BOTH!
4) Finally, on the bottom level, there is a room with chairs. Count!
Once you have all 4 numbers, place them into the safe to open it up! what if you only have one chair? you just put down 1? dont you count the legs on the chair that you see? or no, its just the chair.? and the pumpkins keep moving and disappearing and reappearing. count them as soon as you look into the key hole?
How much do supercomputers cost?
Traditionally the price of Supercomputers have been at least 10 times the price of standard large mainframe computers of the same time period. The price also varied with the model of Supercomputer in a given line (e.g. economy or standard CPU, quantity of memory, speed grade of memory). Early Supercomputers were high performance uniprocessors or high performance uniprocessors with low performance input/output multiprocessors. Only much later did Supercomputer multiprocessors appear using massive numbers of inexpensive commodity microprocessors. However that factor of 10 in price has generally followed.
Relationship between information system and information technology?
Good question! Information system is a bit personal and is business oriented as it focuses on inference and application of computing in the corporate domain. Whereas, information technology is never limited to a single domain but it focuses on selection, integration as well as deployment of computing in various fields.
Information system requires exceptional management skills along with knowledge of technology, to take strategic decisions. Information technology requires technical knowledge of integrating databases as well as networking deployment and development of websites.
To keep it short, Information system is about the corporate side of technology, whereas Information Technology deals with core technical part.

Difference between Ethernet and RS 485?
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
