What is supply chain management system?
North Transportation:
North Transportation is one of the best Supply chain management is the handling of the entire production flow of a good or service, starting from the raw components all the way to delivering the final product to the consumer.
What is the meaning of non-alphanumeric character?
Any character which is not A-Z or 0-9.
Examples of non-alphanumeric characters:
!"£$%^&*()
What does the term record mean in relation to databases?
Record is more a term related to databases than to spreadsheets. However, as you can do some database work using a spreadsheet, then it can be a term used in a spreadsheet. A record in a database is a row of related data, such as the name, age, address and phone number of a person. If it is done in a spreadsheet, with each set of data on a separate row, it can be regarded as being a record.
Electronic machine that accepts data and processes it into information?
By definition a Computer because it "Computes" and "Processes" data.
A component that expands a computer's input storage or output capabilities is referred to as a?
It is main memory (CACHE, RD RAM, D RAM, SD RAM) which expands the system's capabilities.
Greater the capacity of main memory larger the data which is to be processed is kept here, easier is for processr to reach and execute insructions and better the performance is.
Explain why you would format a floppy disk?
Theoretically - it erases all the data on the disc - However...
On a floppy disk, there is a 'reference track' which holds details of each file on the disc (name, start point, size and end point) When you format a disc - the computer ONLY erases the details on this track. Without the reference track information, there is no way for the computer to locate a file.
209752 bytes is equal to how many MB?
Each MB has 1024KB. So 87576KB/1024 gives you 85.5MB.

Violation of intellectual property rights dates back to the early 17th century, before copyright law even existed: when anyone outside the stationers' guild published materials (publishing being exclusive to stationers by royal charter), they were labeled as pirates.
In regard to software piracy, only the final, compiled program was protected by copyright until 1980, when a clear definition for "computer software" was added to US copyright law. Prior to that, source code could be shared without violating copyright.
That being said, illegal sharing of software began almost immediately as the Bulletin Board System grew, starting in the late 1970s; users would download software directly from a BBS, or even just use the BBS to connect with others willing to mail floppy disks. Little action was taken in part because money wasn't changing hands, but also because the software companies knew the BBSs were too poor to bother suing.
What are the stages of information processing cycle?
Again, after processing the data, computer can also store the data into an storage device for future use.
Phase output and storage, are optional. Both of them can be required and vice-versa, as the generated information can also be directly used by another processing cycle where this generated information will be treated as data to be processed.
How many mb is equal to 1.65 gb?
One gigabyte is equal to 1024 megabytes, so 1.65gb would be 1689.6mb.
What layer of the OSI model provides the interface between the user and the data network?
The Transport layer is responsible for taking a message that is too long and breaking it into smaller segments to send out. The reverse is also true, when the information is received the Transport layer is responsible for taking a series of short segments and putting them together again. Hope this helps.
Which is better 16GB or 512MB?
16 GB (gigabytes) is better than 512 MB (megabytes). 512 megabytes is half of one gigabyte.
What are the advantages of a DVD-RW?
I agree that DVD drives hold much more data than their CD cousins. The CD can hold up to only 700 megabytes, which is small by modern standards while a single-layer DVD can hold up to 4.7 gigabytes and a dual-layer can hold up to 8.5 gigabytes. So, in regard to space, the DVD definitely is the king.
Now as to the advantage of the discs with the -RW designation, whether it is the CD-RW or DVD-RW, it means that the disc can be written, erased, and re-written again with different data. This makes such discs very handy for use as "slave discs" for porting data from place to place or for use as backups. Being able to reuse the discs also helps one's budget since the discs do not need to be tossed away after a single burn session. They can be rewritten (at least in theory) up to 1000 times each.
Why is the system called binary?
binary number system used in computers because computer can understand only binary language as it starts from 0and 1. which makes computer easier.
What is the use and need of protocols in computer net work?
Network Protocol are needed because the message or data send by our network have to reached on destination through different networks of different structure and different platform. so network protocols are performing to duty to make our sended data compatible to that new networks, which come in the way to destination.

What does a Laboratory Information Management System or LIMS do?
A Laboratory Information Management System is defined as a computer program that helps to run a laboratory's environment. These systems are dynamic as each lab requires a different information management system depending on the function of the lab.
Databases tend to get split up into a variety of diffrent catagoies based on their application and requirements. All of these diffrent catagories naturally get nifty buzz words to help classify them and make distinctions in features more apparent. The most popular buzz work (well, acronymn anyway) is OLTP or Online Transaction Proccessing. Other classifications include Descision Support Systems (DSS), Data Warehouses, Data Marts, etc.
OLTP databases, as the name implies, handle real time transactions which inherently have some special requirements. If your running a store, for instance, you need to ensure that as people order products they are properly and effiently updating the inventory tables while they are updating the purchases tables, while their updating the customer tables, so on and so forth. OLTP databases must be atomic in nature (an entire transaction either succeeds or fails, there is no middle ground), be consistant (each transaction leaves the affected data in a consistant and correct state), be isolated (no transaction affects the states of other transactions), and be durable (changes resulting from commited transactions are persistant). All of this can be a fairly tall order but is essential to running a successful OLTP database.
Because OLTP databases tend to be the real front line warriors, as far as databases go, they need to be extremely robust and scalable to meet needs as they grow. Whereas an undersized DSS database might force you to go to lunch early an undersized OLTP database will cost you customers. No body is going to order books from an online book store if the OLTP database can't update their shopping cart in less than 15 seconds.
The OLTP feature you tend to hear most often is "row level locking", in which a given record in a table can be locked from updates by any other proccess until the transaction on that record is complete. This is akin to mutex locks in POSIX threading. In fact OLTP shares a number of the same problems programmers do in concurrent programming. Just as you'll find anywhere, when you've got a bunch of diffrent persons or proccesses all grabbing for the same thing at the same time (or at least the potential for that to occur) your going to run into problems and raw performance (getting your hands in and out as quick as possible) is generally one of the solutions.
Several other factors come into place with OLTP databases, and the Oracle10g documentation library even has a whole section dedicated just to OLTP. Find more information in the Oracle10g docs:
When referring to .gif images, the gif stands for Graphic, or Graphics Interchange Format.
How many bytes are in a millibyte?
There are 9.313225746154785e-10 (or 9.313225746154785^-10) millibyte in 1 byte.
The series of instructions that tells the the computer to perform its task?
A program is a sequence of instructions for a computer. Programs are written to tell a computer how to do a specific task.
Divide by 1024 to get how many megabytes, then divide by 1024 to get that many gigabytes.
Approx 0.124 gigabytes.
8 Bits = 1 Byte
1024 Bytes = 1 Kilobyte (kb)
1024 Kilobytes = 1 Megabyte (mb)
1024 Megabytes = 1 Gigabyte (gb)
1024 Gigabytes = 1 Terabyte (tb)
It depends on how long the song is and what quality and compression you have it in. An average 3 - 4 minute song in average quality will be around 3MB or 0.003GB
What are the Specifications of a Macintosh?
