nexus9112 [7]

Answer:

D. Fault tolerance

Explanation:

  • Fault Tolerance basically refers to the feature or capability of a  system to keeps on working and performing its operations without interruption in case of a failure.
  • This failure can be the failure of one or more of its components.
  • This is beneficial as the system does not stop working or fail completely.
  • It provides copies of the same system or backup components which can be used when the existing system fails and prevents the loss of information and services.
  • Accessibility  refers to provide equal services for everyone who uses a system. So its not a correct option.
  • Moore’s law states that the computing speed and power will double every two years so its not a correct option as well.
  • Anti virus is a software to identify, prevent and remove viruses and malware so it is not a correct option as well.

baherus [9]

Answer:

1. Where,

2. From

Explanation:

In SQL query language when working on a database, a user can use certain clauses to carry out some functions.

Hence, The WHERE clause allows us to select only those rows in the result relation of the FROM clause that satisfy a specified predicate.

This is because the "Where clause" selects the rows on a particular condition. While the "From clause" gives the relation which involves the operation.

Given a floating-point formal with a k-bit exponent and an n-bit (fraction, write formulas for the exponent E, significant M, th
ANEK [815]

Answer:

A) Describe the number 7.0 bit

The exponential value ( E ) = 2

while the significand value ( M ) = 1.112  ≈ 7/4

fractional value ( F )  = 0.112

And, numeric value of the quantity ( V )  = 7

The exponent bits will be represented  as :  100----01.

while The fraction bits will be represented  as : 1100---0.

<u>B) The largest odd integer that can be represented exactly </u>

The integer will have its exponential value ( E ) = n

hence the significand value ( M )

=  1.11------12 = 2 - 2-n

also the fractional value ( F ) =  

0.11------12 = 1 – 2-n

Also, Value, V = 2n+1 – 1

The exponent bits  will be represented  as follows:  n + 2k-1 – 1.

while The bit representation for the fraction will be as follows: 11---11.

<u>C) The reciprocal of the smallest positive normalized value </u>

The numerical value of the equity ( V ) = 22k-1-2

The exponential value ( E )  = 2k-1 – 2

While the significand value ( M )  = 1

also the fractional value ( F ) = 0

Hence The bit representation of the exponent will be represented as : 11---------101.

while The bit representation of the fraction will be represented as : 00-----00.

Explanation:

E = integer value of exponent

M = significand value

F = fractional value

V = numeric value of quantity

A) Describe the number 7.0 bit

The exponential value ( E ) = 2

while the significand value ( M ) = 1.112  ≈ 7/4

fractional value ( F )  = 0.112

You want to upgrade a server by installing an external SCSI tape drive. The system currently has a SCSI card and an internal SCS
jeka94

Answer:

You should disable termination on the Small Computer System Interface (SCSI) controller card.

Explanation:

SCSI is an acronym for Small Computer System Interface, which is also generally referred to as host bus adapter (HBA). The SCSI is typically a chip that controls the communication between the operating system (OS), storage devices such as hard disk drives and the host computer system. Also, it helps with the interpretation of the electrical signals between the Small Computer System Interface (SCSI) bus and the input-output bus for storage devices.

In this scenario, you want to upgrade a server by installing an external SCSI tape drive. The system currently has a Small Computer System Interface (SCSI) card and an internal SCSI hard drive. At bootup, the system fails to recognize the new tape drive. To solve this problem, you should disable termination on the SCSI controller card so that only the external SCSI tape drive will be active and the SCSI won't be detected.
