I guessed D, taking it right now, sorry if it's wrong
Explanation:
Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file
Answer:
C. External Data
Explanation:
On the External Data tab, you can find import and export commands located in Access.
Connection to the gigabit ethernet network must be done with Cat6 Cable. Using the wireless ethernet router as the network device and connecting the cable to the printer must be done with Cat5e Cable.
We can arrive at this answer because:
- The Cat6 Cable will be responsible for establishing a bridge between the gigabyte Ethernet and the network device, allowing data delivery to be made between the two systems.
- This connection must be made with a wireless device, to keep it more stabilized and it needs, mainly, for the notebook to receive the internet signal. This will be done using the wireless ethernet router.
- The printer needs a softer, less rigid connection, so a Cat5e cable will be a convenient option.
In this case, we can see that using these devices will allow Lori to have a more stable and efficient connection to meet her needs.
