What is difference between symmetric and asymmetric compression?
Wiki User
∙ 13y ago
A data compression technique that takes about the same amount of time to compress as it does to decompress.
asymmetric compressionA data compression technique that typically takes more time to compress than it does to decompress. Some asymmetric compression methods take longer to decompress, which would be suited for backup files that are constantly being compressed and rarely decompressed.

How does asymmetric encryption provide confidentiality?
Asymmetric encryption can provide confidentiality in two ways:1) messages encrypted using the public key of the recipient can only be decrypted using the private key of the recipient - which only the recipient should possess.2) It can be used as part of a negotiation process between two users to establish a temporary shared key through a process such as the following:User A sends a challenge message to user B which is encrypted with user B's public key to initiate secure communications.User B decrypts the message and sends the correct response back to user A encrypted with user A's public keyThe two users are now authenticated to each otherAt this point A can send a proposed symmetric key to B encrypted with B's private keyAll further communications are encrypted via the shared symmetric keyIn this second scenario, the asymmetric encryption only facilitates the establishment of confidentiality via the eventually shared symmetric key by securing the initial negotiations.
What is the difference between MPEG JPEG and?
1. JPEG stands for joint photographic expert group and MPEG stands for motion picture expert group. 2. JPEG is used for picture compression and MPEG is used for video compression. 3. JPEG typically achieves 10:1 compression with little perceptible loss in image quality, whereas compression ratio in MPEG is 30:1 for general video using H.263 and 50:1 for general video using H.264/MPEG4. 4. JPEG and MPEG both uses lossy compression.

Difference between symmetrical and assymetrical data of statistics?
Asymmetric is the opposite of symmetric
What is the difference between symmetric and asymmetric information?
Symmetric means the same each side, assymetric is different each side.
What is the Difference between symmetric and asymmetric design?
Symmetric means that the design of the image is balanced and both sides are equal. An asymmetric image is when the design does not repeat itself so if you fold it in half the designs will not meet in the same areas.
Describe the differences between symmetric and asymmetric multiprocessing?
use/ application
Difference between asymmetric and symmetric multiprocessing and simple multiprocessors?
A symmetric multiprocessing (SMP) system is one in which each processor runs an identical copy of the operating system on each processor. In an asymmetric multiprocessing, system, each processor is assigned a specific tasks. An example of this would be a master- slave relationship between one processor and “the rest”.
Difference between symmetric and asymmetric key cryptography?
Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key. This eliminates the need of having to give someone the secret key (as with symmetric encryption) and risk having it compromised. The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric. If you do a quick search on the differences between symmetric and asymmetric you can find many more explanations. This just a quick overview.

What is the difference between compression and tension?
the difference is that compression is like pushing something together and tension is like pulling something appart
Difference between symmetric and asymmetric processors?
in assymetric processor the operating system typically sets aside one or more processors for its exclusive use while in symetric processors are used to get higher levels of performance, any processor here can run any type of thread, they communicate with each other through shared memory
