Answer:
Charles Babbage (1791-1871), computer pioneer, designed two classes of engine, Difference Engines, and Analytical Engines. Difference engines are so called because of the mathematical principle on which they are based, namely, the method of finite differences.
Explanation:
D prevent the formation of rust
To convert binary fraction to decimal fraction, we first write the given
.1011 (base 2)
The process of conversion is to break down to its decimal constituent,
.1011 (base 2) = (1*2^-1)+(0*2^-2)+(1*2^-3)+(1*2^-4)
.1011 (base 2) = 0.5 + 0 + 0.125 + 0.0625
.1011 (base 2) = 0.6875 (base 10)
<em>ANSWER: 0.6875 (base 10)</em>
Answer:
The Session layer (Layer 5)
Explanation:
The OSI (Open Systems Interconnection) seven-layer model is a reference model that explains how devices (or applications) communicate over the network. The model consists basically of seven different layers which are;
i. Layer 1 or the physical layer
ii. Layer 2 or the data-link layer
iii. Layer 3 or the network layer
iv. Layer 4 or the transport layer
v. Layer 5 or the Session layer
vi. Layer 6 or the presentation layer
vii. Layer 7 or the application layer.
Out of the seven layers, the session layer (layer 5) keeps track of a system's connections to send the right response to the right computer by setting up, coordinating and managing these connections. It controls, establishes and maintains the connection between multiple computers or applications on a computer.
