Answer:
Software that is embedded in hardware.
Explanation:
It is permanent software programmed into a read-only memory.
A local server means that you have a server setup on your current machine. A remote server is ran on a different machine
Answer:
Data modeling occurs at three levels—physical, logical, and conceptual.
- A physical model is a schema or framework for how data is physically stored in a database.
- A conceptual model identifies the high-level, user view of data.
- A logical data model sits between the physical and conceptual levels and allows for the logical representation of data to be separate from its physical storage.
Answer:
15.7 ; 78.5
Explanation:
Mechanical advantage of a screw = Circumference / pitch
Circumference = pi × d
Where :
pi = 3.142, D = diameter
Therefore ;
Circumference = 3.142 × (1/4) = 0.785 in
Pitch = 1/TPI
TPI (thread per inch) = 20
Pitch = 1/ 20 = 0.05
Mechanical advantage = 0.785 / 0.05 = 15.7
Resistance force if effort force is 5lb
Mechanical advantage = Fr / Fe
Fe = effort force, Fr = resistance force
15.7 = Fr / 5
Fr = 15.7 × 5 = 78.5 lbs
Explanation:
Step one
The maximum size of data field in each fragment = 480
(because there are 20 bytes IP header) Thus the number of required
fragments 
thus the number of required fragment is 4
Step two
Each fragment will have identification number 291. each fragment except the last one will be of size 500 bytes (including IP header). the offset of the fragments will be 0, 60, 120, 180. each of the first 3 fragments will have
flag = 1; the last fragment will have flag =0
