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: True
Explanation:Orthogonal instruction set is the set of instruction that can use can use all addressing mode. They have independent working and so instruction can use any register the prefer and this leads to overlapping in instruction and complexity.
When RISC architecture got introduced ,it got more preference due to reduced instruction and less complexity as compared to orthogonal instruction.So it not considered elegant to have more orthogonal instruction.
I believe lightbulbs have different brightness because of there quality parts that make it. The cheaper they are usually the worse quality. That is my theory.
Answer:
Spin button.
Explanation:
Spread sheet applications are softwares used to analyze and manipulate data for clean and easy data presentation.
It is composed of columns or fields and rows or records to make a worksheet of a workbook in the application. Each box on the worksheet is called a cell.
Data can be inputted directly to a cell or with functions and formulas and with the form control feature.
Form control is use to specify the range of input to use in cells for easy data input. The spin button of the form control is used to input data by pressing the up and down arrow key on the keyboard.
