What is the difference between http1.0 and http1.1 version?
salam http 1.0 establishes a TCP connection for each packet http 1.1 uses only one connection for all packets
What is difference between WEP 64 and WEP 128?
The 64 bit WEP key uses a 40 bit (10 Hex character) Encryption and a128 bit WEP key uses a 104 bit (26 Hex Character) Encryption.So the 128 bit WEP key is a higher level of encryption compared to 64 bit WEP.
What is difference between natural key and surrogate key?
Surrogate Key: Surrogate keys are keys that have no "business" meaning and are solely used to identify a record in the table. Such keys are either database generated (example: Identity in SQL Server, Sequence in Oracle, Sequence/Identity in DB2 UDB etc.) or system generated values (like generated via a table in the schema). Natural Key: Keys are natural if the attribute it represents is used for identification independently of the database schema. What this basically means is that the keys are natural if people use them example: Invoice-Numbers, Tax-Ids, SSN etc.
Using foreign key on ER diagram?
Foreign keys isnt drawn at a ER-diagram. The relation drawn between entities is enough to show, that der is at foreign key
Can you explain the key differences between fem and fvm in the context of computational fluid dynamics"?
In computational fluid dynamics, the key difference between Finite Element Method (FEM) and Finite Volume Method (FVM) lies in how they discretize and solve fluid flow equations. FEM divides the domain into smaller elements and uses piecewise polynomial functions to approximate the solution, while FVM divides the domain into control volumes and solves the equations at the center of each volume. FEM is more flexible for complex geometries, while FVM conserves mass and energy better.
