What are the advantages and disadvantages of online information sharing?
Advantages of File Sharing In a file sharing environment, a large number of users can access a program as though it were on their local machines, when actually the program resides on a single file server. This is a great benefit to small workstations, where disk space is at a premium. A user can have access to a much larger program repertoire than could fit on a private disk. By having a resource reside physically on a single server, then distributed throughout the network, you can greatly simplify administration. First, you reduce the number of copies of various programs that need to be maintained on the network. Second, you reduce the problems involved in performing backups for a number of machines dispersed over a wide geographical area. By keeping files in a single location, this task becomes comparable to backing up a single machine. Centralizing files on a few file servers not only simplifies administration, it helps maintain consistency of shared data files. When changes are made to a shared file, they become available to all users immediately. Disadvantages of File Sharing 1) Security Problems- explicit programming required
2) Integrity Problems- rules needed to be programmed explicitly
3) Concurrent access anomalies- multiple access of same file in case of multiple user system
4) Data Isolation- related data required by different programs of same application may resides in diff isolated files
5) Unanticipated queries- handling sudden queries can be difficult
6) Data redundancy
7) Data inconsistency
8) Duplication of data
9) No standardized control over organization of files
10) No standardized control over structure of files

It should be easy to tell. Basically, just look around the outside of the computer. If you see and apple, then it's a Mac. If you see something like "Dell", it's a PC
Can you enter the CMOS setup after the computer system has booted up?
Generally, no, you cannot enter the CMOS setup after you have booted. But it depends on the exact computer and if there is a separate CMOS configuration tool. In fact, the IBM AT was like that, and it required a separate setup program that ran after the computer booted. Some of the modern computers will let you change certain CMOS settings on the fly if you install a utility their utility for doing that.
What is streaming an audio file?
That term is used when you receive data on the computer while you use it, as opposed to downloading a complete file and THEN using it. For example, when you listen to online radio, you don't need to download a complete MP3 (or similar) file first, to listen to it.
What are two types of PATA data cables?
Under parallel ata, two types of ribbon cable are used. The 80-conductor ide cable has 40 pins and 80 wires Forty wires are used for communication and data, and an additional 40 ground wires reduce crosstalk on the cable. An older 40-conducror cable has 40 wires and 40 pins. the two types of cables are PATA and IDE cables which come in a 80-conductor IDE cable and a 40-conductor cable

Should i put my computer in hibernate or standby mode?
Well its hard to asess because ethier or, could work. Personally i leave my computer in standby mode most of the time. But there are some times that you will need to shut down and it is a healthly choice to shut down the computer every now and then like maybe every second day? Now another thing is, if you are an IT student that needs to run from class to class evry hour i'd suggest just leaving it in standby mode because it takes way too long to boot up after you shut down.

When did schools begin to put computers into classrooms?
by 1989 nearly every school district across America had computers in the classrooms. But computer usage began prior to 1975. Colleges used mainframes to do statistical problems with and simple administrative jobs.
A software fault is a possibly recoverable error that occurred because of a programming error. Such faults are usually detected by hardware, and sent to the appropriate software handler for processing. For example, a division by zero error will generate a DIVBYZERO fault, which will be sent to the software's try-catch block (or coding equivalent), or will eventually filter up to the operating system, at which point the program will cease execution. In Windows, this is generally manifested as a "General Protection Fault," or the "we're sorry, this program has encountered an error and must close" box. If the fault is caught by the software, it can correct the condition and try again.
This is in contrast to a hardware fault, which indicates a malfunctioning device. Usually, only an operating system can see these faults (no application can directly touch hardware in a modern operating system). In some causes, a significant hardware fault will cause the operating system to fail entirely, and shutdown, stop with an onscreen message (the so-called Blue Screen of Death), or reboot. For example, a RAM chip goes bad during use, or a hard drive fails.
How you can make a computer better?

What is the most appropriate type of network for connecting computers in a single building?
he United Kingdom of Great Britain and Northern Ireland[note 7] (commonly known as the United Kingdom, the UK or Britain) is a sovereign state located off the northwestern coast of continental Europe. It is an island country,[10][11] spanning an archipelago including Great Britain, the northeastern part of the island of Ireland, and many small islands. Northern Ireland is the only part of the UK with a land border, sharing it with the Republic of Ireland.[12][13] Apart from this land border, the UK is surrounded by the Atlantic Ocean, the North Sea, the English Channel and the Irish Sea. The largest island, Great Britain, is linked to France by the Channel Tunnel.
The United Kingdom is a constitutional monarchy and unitary state consisting of four countries: England, Northern Ireland, Scotland and Wales.[14] It is governed by a parliamentary system with its seat of government in London, the capital, but with three devolved national administrations of varying powers[15][16] in Belfast, Cardiff and Edinburgh, the capitals of Northern Ireland, Wales and Scotland respectively. The Channel Island bailiwicks of Jersey and Guernsey, and the Isle of Man are Crown Dependencies, which means they are constitutionally tied to the British monarch but are not part of the UK.[17] The UK has fourteen overseas territories,[18] all remnants of the British Empire, which at its height in 1922 encompassed almost a quarter of the world's land surface, the largest empire in history. British influence can still be observed in the language, culture and legal systems of many of its former colonies.
The UK is a developed country, with the world's sixth largest economy by nominal GDP[19] and the sixth largest by purchasing power parity.[20] It was the world's first industrialised country[21] and the world's foremost power during the 19th and early 20th centuries,[22] but the economic and social cost of two world wars and the decline of its empire in the latter half of the 20th century diminished its leading role in global affairs. The UK nevertheless remains a major power with strong economic, cultural, military, scientific and political influence. It is a recognised nuclear weapons state and has the fourth highest defence spending in the world.[citation needed] It is a Member State of the European Union, a permanent member of the United Nations Security Council, and is a member of the Commonwealth of Nations, G8, G20, NATO, OECD, and the World Trade Organization.
hope this helped you :)
How do you fix CD-ROM problems?
If you're unable to open the drive, use a small paper clip to insert it in a very small hole in the front panel of the CD-ROM drive. Use a small paperclip and insert it in the hole. You will feel a sprocket type of wheel. Once you feel that you can push the wheel, do so, the tray will open slightly. You can then pull out the tray entirely using your fingers. If the drive was working properly and is no longer reading, most likely the drive is bad or corruption of the CD-ROM drivers. To eliminate the damaged drive, go to Driverguide, find the drivers for CD-Rom's and reinstall them, you may already have the divers on a CD which came with the computer. There's no charge for signing up. If that doesn't work, you can swap another CD-ROM from an older computer or purchase one at a local computer parts store. "Best Buy" stores usually has very good prices or try EBay. It's very simple to exchange. Open the case, look for the 4 small screws, 2 on each side of the case. Make sure you have the settings correct on the CD-ROM drive. Look at the back of the drive once you pull it out. You'll see 3 settings marked as CS, MA or SL. MA is Master drive, SL is the Slave drive, CS is sometimes used a s Auto, however, it is best to move the "Jumper" ( a very small 2 pin connector, usually black in color, sometimes it varies) it looks like a small square that connects 2 pins. Place this jumper in the same position as the former CD drive. Make sure that the IDE connector cable, Grey in color, is connected the same way. The grey cable has a RED line on one side, meaning PIN#1 which is the pin closest to the power supply cable. Note-make sure the power supply cable is also attached to the 4 pin connector. This may also be your problem if you recently removed or made changes to the cables or jumpers. The RED side of the grey cable needs to be the side which goes into pin#1. If you have 2 devices both connected as Master or Slave, your drives will not function. 1 drive must be Master, the other Slave. Both devices must also be aligned with the RED line on the grey cable connected to PIN#1 on both devices.
