What is the difference between plus R and -R DVD?
Types of recordable CD and DVD media If your computer has an internal or external recordable optical drive supported by Apple, you can "burn" (record) your favorite music, applications, documents, digital photos and video, and other digital files to recordable CD and DVD discs. You can create your own music CDs and play them on a standard audio player, or create DVDs with movies and slideshows and play them on a DVD player. There are several types of recordable CD and DVD media: DVD-R discs hold about 4.7 GB of information. You can burn files on a DVD-R disc using the Apple SuperDrive. DVD-R discs are not reusable; you can burn files on them only once. DVD-RW (DVD-Rewritable) discs hold about 4.7 GB of information on each side. If you have an Apple SuperDrive, you can read information on these discs, but you can't burn files on them using Mac OS X. DVD-RW discs are reusable: you can burn files on them, erase them, and then burn again (if you have an application that is compatible). CD-RW (CD-Rewritable) discs come in normal and high-speed formats. You can burn files on CD-RW discs using the Combo drive (or another supported CD burner). CD-RW discs are reusable: you can burn files on them, erase them, and then burn again. CD-R (CD-Recordable) discs come in two types. One holds 74 minutes of audio, or about 650 MB of information. The other holds 80 minutes of audio, or about 700 MB of information. You can burn CD-R discs using the Combo drive (or another supported CD burner). For recording audio CDs, it is best to use CD-R discs because most standard audio CD players cannot read CD-RW discs. For longer-term storage and reliability, use CD-R discs. You can't burn anything on a CD-ROM or DVD-ROM disc.

What is role of system analyst and who is system analyst explain function of system analyst?
The role of system analyst : System analyst is the person who is responsible for the analysis of the system. He is the person who is responsible to deal with the customers and gather his requirements. He gathers the information about the key requirements of customer by asking questions, writing down the answers, organizing mock interview with the customers etc. He prepares the analysis model to achieve three primary objectives.
(1) To describe what the customer requires.
(2) To establish a basis for creation of software design.
(3) To define a set of requirements that can be validated once the software is built.
He collaborates a set of requirements that can be established during earlier requirement engineering tasks and build model that depict user scenarios, functional activities , problem classes and their relationships, system and classes behaviour and flow of data as it transformed. In early stages he focuses on what and not how.He decides what objects must system manipulate, what function must the system performs, what behaviour does the system exhibit, what interfaces are defined and what constraints to apply. If customer is precisely unsure of what he wants then analyzer decides to apply specific approach to accomplish function and performance.
The pure definition of a Systems Analyst is a programmer or consultant who designs and manages the development of business applications. Typically, systems analysts are more involved in design issues than in day-to-day coding. However, systems analyst is a somewhat arbitrary title, so different companies define the role differently.
Typical Position Description:
*Gather and analyze organizational data for developing information systems.
*Study existing business procedures and computer programs
to determine how both could be better organized and structured for the betterment of the organization.
*Study technological and business trends to be able to recommend changes to technology and business process to take advantage of advances in both.
*Design and guide the implementation of business computed-based information systems.
*Prepare and present reports to management as needed.
Typical Duties
1. Analyze existing business operations and existing information systems (computerized or not).
2. Study trends in technology.
3. Study trends in business and be aware of competitors' exploitation of technology.
4. Propose alternative solutions to business problems and select preferred solution. Justify selection.
5. Recommend technology products (hardware and software) for purchase.
6. Design new systems including process flow, user interface, reports, and security procedures.
7. Prepare training material for users of new system.
8. Supervise implementation of new system.
Most Desired Skills and Qualities
1. Excellent communication abilities (oral and written).
2. Problem solving.

Faster access time, greater cost per bit; greater capacity, smaller cost per bit; greater
capacity, slower access time.
As a general rule (but there are exceptions) the greater the capacity of a memory the longer the access time. For a higher cost the access time of a given capacity memory can usually be shortened some.
As a general rule (but there are exceptions) the greater the capacity of a memory the total memory cost increases, but the memory cost per bit decreases.
How many bits in 20 mega bytes?
1 Bit is the smallest recordable state ( Zero or One / ON or Off / High or Low ) 1 Byte is 8 Bits which can represent a number upto 256 ( 2**8) or a character 1 KiloBytes (KB) is 2**10 Bytes == 1024 Bytes //// "Slang" as One Thousand 1 MegaBytes (MB) is 2**20 Bytes = 2**10 * 2**10 Bytes 1,045,876 Bytes //// "Slang" as One Million 1 GigaByte (GB) is 2**30 == 1,073,741,824 //// "Slang" as One Billion So 20 Gigabytes is 20 * 2**30 Bytes 1 TeraByte (GB) is 2**40 == 1,099,511,627,776 //// "Slang" as One Trillion From the above, you can see why a 32 bit operating system can address upto 4 GB of memory (2**32 4GB if your computer has 4GB of RAM and a 32 bit OS, it will not be able to address it all since some of that address is used by video cards and other devices. This is why most PCs have either 3GB (or less) with a 32 bit OS or MORE & MORE ( 4+GB with 64 Bit OS)
KB - Kilo Byte
MB - Mega Byte
GB - Giga Byte
TB - Tera Byte
while you may think kilo is 1000 and mega is 1 million... giga is 1 billion... and so on; it actually is not. a Kilo byte is actually 2^10 Byte which is 1024 Bytes.
Kilo Byte = 2^10 Bytes = 1024 Bytes
Mega Byte = 2^20 Bytes = 1048576 Bytes
Giga Bytes = 2^ 30 Bytes = 1073741824 Bytes
and so on... close enough right?
3200 Mb equals to how many gigabytes?
32000000 Bytes / 1024 = 31250 KBytes 31250 KBytes / 1024 = 30.5 MBytes
30.5 MBytes / 1024 = 0.02978515625 ... Gigabytes
How many terabytes are in one petabyte?
There are 1000 terabytes (TB) in a petabyte (PB). There is an older definition based on multiples of 1024 instead of 1000, but this was changed, and tebibytes and pebibyte are the ones based on multiples of 1024.
Computer Manufactures consider it being 1000. But the OS will say 1024 (due to the binary numbering).
Here is the memory ladder according to computer manufactures
- 8 bits= 1 Byte
- 1000 bytes= 1 Kilobyte
- 1000 Kilobytes= 1 Megabyte
- 1000 Megabytes= 1 Gigabyte
- 1000 Gigabytes= 1 Terabyte
- 1000 Terabytes= 1 Petabyte
- 1000 Petabytes= 1 Exabyte
- 1000 Exabytes= 1 Zettabyte
- 1000 Zettabytes= 1 Yottabyte
Here it is according to binary prefix and the older numbering system:
- 8 bits= 1 Byte
- 1024 bytes= 1 Kilobyte
- 1024 Kilobytes= 1 Megabyte (1 048 576 bytes)
- 1024 Megabytes= 1 Gigabyte (1 073 741 824 bytes)
- 1024 Gigabytes= 1 Terabyte
- 1024 Terabytes= 1 Petabyte
- 1024 Petabytes= 1 Exabyte
- 1024 Exabytes= 1 Zettabyte
- 1024 Zettabytes= 1 Yottabyte
How do you transfer filesfolder from one drive to another drive?
The best way to do it is to right click the original file and select "copy." Then proceed to "My Computer" locate the second drive and open it. Once it is opened right click any empty space and select "Paste." Good luck!
What Difference between electronic and electrical devices?
what exactly is the difference between electrical devices and electronic devices?
The answer lies in how devices manipulate electricity to do their work. Electrical devices take the energy of electric current and transform it in simple ways into some other form of energy - most likely light, heat, or motion. The heating elements in a toaster turn electrical energy into heat so you can burn your toast. And the motor in your vacuum cleaner turns electrical energy into motion that drives a pump that sucks the burnt toast crumbs out of your carpet.
In contrast, electronic devices do much more. Instead of just converting electrical energy into heat, light, or motion, electronic devices are designed to manipulate the electrical current itself to coax it into doing interesting and useful things.
That very first electronic device invented in 1883 by Thomas Edison manipulated the electric current passing through a light bulb in a way that let Edison create a device that could monitor the voltage being provided to an electrical circuit and automatically increase or decrease the voltage if it became too low or too high.
One of the most common things that electronic devices do is manipulate electric current in a way that adds meaningful information to the current. For example, audio electronic devices add sound information to an electric current so that you can listen to music or talk on a cellphone. And video devices add images to an electric current so you can watch great movies until you know every line by heart.
Keep in mind that the distinction between electric and electronic devices is a bit blurry. What used to be simple electrical devices now often include some electronic components in them. For example, your toaster may contain an electronic thermostat that attempts to keep the heat at just the right temperature to make perfect toast.
And even the most complicated electronic devices have simple electrical components in them. For example, although your TV set's remote control is a pretty complicated little electronic device, it contains batteries, which are simple electrical devices.

*You will get option share this folder
* At the bottom you have also option for the permission.
Users, computers, and groups (collectively known as "security principals") that are stored in Active Directory are assigned Security Identifiers (SIDS), which are unique alphanumeric numeric strings that map to a single object in the domain. SIDS consist of a domain-wide SID concatenated with a monotonically-increasing relative identifier (RID) that is allocated by each Windows 2000 domain controller in the domain. Each Windows 2000 domain controller is assigned a pool of RIDs by the RID flexible single-master operations (FSMO) owner in each Active Directory domain. The RID FSMO is responsible for issuing a unique RID pool to each domain controller in its domain.
What is the difference between raw data and information?
On TI data is referring to the minimum capacity of storage that is represented by a bit, so you can have for minimum 1 bit of information or what is the same, the possibility of represent only two values 0,1 that is the base of the binary code or the machine language.
For an instance you can have 2 megabytes of data but in this moment is only data that can't be used right away as knowledge because it haven't be processed by applying intelligence of any kind that give us meaning for an event or that describe an entity; It`s only then when it became in information an let's remember that data is storage as megabytes and when it's information you storage in bits.
So it's different to have 2 megabytes(of data) than 2 megabits(of information).
What is the most common protocol for computer networking?
ip - internet protocol.
The Internet uses many layered protocols. The two protocols used the most are tcp/ip (tcp protocol on top of ip) and udp/ip (udp protocol on top of ip). Web browsers use tcp/ip. Email uses tcp/ip. Many web applications and games use udp/ip for broadcasting video, audio, and for multiplayer games.
ip runs within/on yet many other base protocols. The most common protocol inside homes and business is ethernet. tcp/ip can run on ethernet and many other base protocols.
Analogy: Think of shipping and boxes as protocols and packets. You might ship something in a box to another country. The address system on the box could be part of the ip protocol. Your box goes in a UPS truck (a bigger box - think ethernet packet holding your ip packet) with other boxes then goes to a distribution center (a router), then maybe into a container and on a ship (a different box - say FIOS fiber protocols). So tcp within ip within ethernet is like ups package within container on a container ship.
In networks the containers can but don't always get bigger as you get onto the backbone - they tend instead to get faster. An ethernet packet might contain 2 different ip packets each which might have 2 tcp packets. More often it is a 1 to 1 relationship.
1 byte = 8 bits
1 megabyte = 1 million bytes = 8 million bits
That's the rounded, popular version.
To be perfectly technical and accurate about it, "One megabyte" refers to
a unit of data communication or storage that consists of 1,048,576 bytes,
which is 8,388,608 bits. The reason is that the count of digital storage
capacity and addressability is always a power of 2 .
What is the diff between MB and KB?
A MB(Megabyte) is a thousand KB(Kilobytes). So: 1 MB=1000KB it starts from bits: 8 bits=1 byte 1000 bytes=1 KB 1000KB=1MB and 1000MB=1GB (GigaByte)
Computer storage devices include any hardware that stores data. The most common type of storage device is a hard drive. The computer's primary hard drive stores the operating system, applications, and files and folders for users of the computer.
While the hard drive is the most known of all storage devices, other common types exist as well. Flash memory devices, such as USB drives and iPod nanos are popular ways to store data in a small, portable format. Other types of flash memory, such as compact flash and SD cards, are popular ways to store digital camera images.
External hard drives which use USB and Firewire sockets are common too. These types of drives are often used for video and photo storage, backing up internal hard drives, or for simply adding extra storage. Tape drives are another type of storage device. They are an older technology and use reels of tape to store data. They are typically used for backing up data.
Storage device hierarchy is comprised of the settings that determine the order that the storage devices are accessed. While that has traditionally been determined by the cable positions and jumpers on the drives, this is now a CMOS setting as well. The reason for that is because there are so many different types of storage devices, and any of them can be bootable. So without such a CMOS setting, there is no way for the bootloader and OS to know the order of the drives.
