Answer:
usable capacity = 10 GB
Number of cylinders = 256
Block size = 4 KB
(1)Bytes in each cylinder = (10*230)/(256) = (10*222) = 40 MegaBytes
(2)Number of Blocks in each cylinder = (10*222)/(212) = 10K
(3)capacity of one track = 40 MegaBytes/(10*2) = 2 MB
Rotation speed = 3840 RPM
Number of rotations per second = 3840/60 = 64
Transfer rate = (2*64) = 128 MB/sec

Explanation:
The following code is written in Java. It creates the abstract dollar class that has two instance variables for the dollars and the coins that are passed as arguments. The test output can be seen in the picture attached below.
class Dollar {
int dollars;
double coin;
private Dollar(int dollar, int coin) {
this.dollars = dollar;
this.coin = Double.valueOf(coin) / 100;
}
}

Answer:
Wired equivalent privacy standard has the significant disadvantages as, it is uses the static encryption keys. Wired equivalent privacy are the security and the privacy protocol which are used for designing the wireless local area network. And the static encryption key are used to set up the router for encrypting the packet in the device. The main disadvantage is that it enables the MAC address and it is easily detectable by the hackers.
Answer: A) systems analysis phase of the SDLC.
Explanation:
In accordance with system development life cycle(SDLC) , analysis phase is the stage where all the requirement and materials for the system are collected and ordered.The requirements are in the form of input and output which are extracted and documented to provide clear vision of outcome.
- Other options are incorrect because design phase is for designing the format ans structure of system through input components. Planning and selection stage is making scheme through opting correct requirement for system.
- Implementation and operation phase is the stage of implementing the components on system structure to make them perform their respective tasks. Logic modelling level is defining inputs , components, outputs in logical manner so that they provide desired result operating.
- Thus, the correct operation is option(A).
