What are some of the advantages and disadvantages of using an independent news source?
PROS ARE:
that you wrote them and the information is all yours.
that it won't go public if you don't want it to be out there.
you can keep it for yourslef, as in self profit.
you can share it with the people you want to share it with.
you wont have to be interigated.
etc.
CONS ARE:
you can get the information stolen if it's not copy written.
people can make it globle if you're not carful.
people can get envious and try to destroy it.
What is anatomy of computer system?
any computer system essentially has 3 parts namely input device,centra
What are the disadvantages of zigbee?
The main advantages of ZigBee are:
- Power saving, as a result of the short working period, low power consumption of communication, and standby mode
- Reliability: Collision avoidance is adopted, with a special time slot allocated for those communications that need fixed bandwidth so that competition and conflict are avoided when transmitting data. The MAC layer adopts completely confirmed data transmission, that is, every data packet sent must wait for the confirmation from the receiver
- Low cost of the modules, and the ZigBee protocol is patent fee free
- Short time delay, typically 30 ms for device searching, 15 ms for standby to activation, and 15 ms for channel access of active devices
- Large network capacity: One ZigBee network contains one master device and maximum 254 slave devices. There can be as many as 100 ZigBee networks within one area
- Safety: ZigBee provides a data integrity check and authentication function. AES-128 is adopted and at the same time each application can flexibly determine its safety property.
The main disadvantages of ZigBee include short range, low complexity, and low data speed. Due to their high cost, GSM and GPRS are normally used in concentrators to transmit data to the main station, or in high end multi-function meters. ZigBee is used mainly in the concentrators, data collectors, repeaters, and meters installed in the urban distribution AMR systems and prepayment systems. Because of the good real time capability of RF, meters are often equipped with a remote control function.
What is it called to process of copying a file from the Web to your computer?
Downloading is copying a file from the Web to your computer.
Which computing technology sse1 sse2 sse3 or sse4 better supports data-mining applications?
Which computing technology (SSE1 SSE2 SEE3 or SSE4) better supports data-mining applications
What does the computing term backward compatibility mean?
The computing term "backward compatibility" refers to the ability of a model, software, or other computer object that can work properly with earlier models and versions. Many PDF files for example are compatible with earlier versions of PDF reader.
When was Symposium on Theory of Computing created?
Symposium on Theory of Computing was created in 1969.
Which RAID in computers is the fastest?
RAID 0 is generally the fastest RAID level. It uses two hard drives at the same time, with each drive sending and receiving different data. The data is usually "striped."
Why does Microsoft make the crappiest computers on earth?
Microsoft does not make personal computers. They make the software/Operating System that allows your computer to operate. Companies like Dell, HP, ASUS, Acer, Sony, etc. make the actual physical computers (Hardware). And Microsoft's Operating system is what makes them work; which is called Windows. There are different versions of Windows, the most Current are: XP, Vista, Windows 7, and soon to come is Windows 8.
Macs are different because Apple makes the physical computer and the operating system which allows the computer to run. Apple computer's personal computers are know as MACs'. And the Operating system is called OSX. There are different types of OSX, such as: Snow Leopard and Lion. The notion that Apple makes their own Computers and Operating system is one of their major selling points "Everything just works" (STEVE JOBS).
Another not so common, but FREE and underrated Operating System is known as Linux. Similar to OSX and Windows, LINUX has different Distributions (versions) such as Ubuntu, OpenSUSE, Fedora, and Slackware. Linux can be run on any computer, and has the most variety of the three companies we just talked about.
What approach opens an application program and then creates a document?
documentation-centric approach
1. Introduce yourself, and who you represent. Complement something nice you see around you in their yard or house.
That would depend on the network topology chosen and the type of network connectivity devices employed.
In a properly constructed, switched and/or routed network the answer would be NO.
If hubs or repeaters are used to connect devices and/or network segments, then yes.
In a bus or ring topology, the answer is yes. Whether anything is done with the frame is a different matter and depends on whether you consider the network adaptor to be integral to the computer.
What percent of computer users worldwide use Microsoft?
Some reports have quoted the figure 91.46% of computer uses, but this figure does not include Apple Macs.
Why is it so important to back up the contents of a disk?
If you don't back up discs you are taking a massive risk in data protection. You could lose all your work and potentially your hard drive (if you don't back that up). This can be really bad. I know for a fact. I had a computer studies assignment that required me to use a disc for protection. It went corrupt. 10 minutes before the assignment was due. It was not pretty at all.
What are features of fourth generation computers?
They use a device called Microprocessor. They are smaller in size.
They are cheaper and faster.
They are very easy to handle.
Examples: IBM 4300, ICL 2900.
What is the difference between a column constraint and a table constraint?
column constraint is for a single column. table constraint is for an entire table.
Not too old at all. It's much better than watching television.
