ICT Test

ICT- is:

• It is a programmer or computer for getting special information from another compute

• Are the technologies used in the conveying, manipulation and storage of data by electronic means

• Commercial organization

• (TCP/IP) Portal

• Server Optimization and Virtualization 

Data centers include:

• Self-service on demand

• Resource pooling

• Elasticity

• Highly reliable server hardware

• Universal access network

Cloud computing users:

• Self Service department

• Universal gamers

• Resource pooling

• Web Services for connections

• Hackers

An infrastructure where both the data storage and processing happens outside the mobile device:

• Universal access network

• Resource pooling

• Mobile Cloud Computing

• Self service

• Universal work

RSA encoding algorithm:

• Two primes p and q and let n = q, let p, φ(n) = (a-1)(n-1)

• Two primes p and q and let n = p*q, let a, φ(n) = (p-1)(q-1), e*d ≡ mod φ(n). The public key is the pair (n, e), the private key is (n, d)

• Two primes p and q and let n = p/q, let a, φ(n) = (p-2)(q-3), The public key is the pair (n, d), the private key is e.

• Let the number e be such that the numbers e and φ(n) are relatively compaund, and d is multiplicatively proportional to it, that is e/d ≡ mod φ(n).

• Let the number e be such that the numbers e and φ(n) are relatively prime, and d is multiplicatively inverse to it, that is e-d ≡ mod φ(n).

Integrity of information can be divided into:

• Flexible

• Compound

• Sophisticated

• Stable, Unstable

• Static, Dynamic
