Explanation:
Answer:
The answer is "2".
Explanation:
In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:
Given values:
Bandwidth = 64 kbps
Data frames = 512 bytes
Propagation Time (tp ) =270 ms
Change Bandwidth kbps to bps:
1 kb= 1024 bytes
calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps
1 bytes = 8 bits
512 bytes = 512 × 8 = 4096 bits
Frame length = 4096 bits
Formula
Transmission time (Tt) = Frame length /Bandwidth
Window size = 1+2a
where a = Propagation time/Transmission time
Calculate Transmission time:
Transmission time (Tt) = 4096 / 65536
Transmission time (Tt)= 625 m.sec
Calculate Window size:
Window size = 1+2(270/625)
Window size
= 1+2(0.432)
Window size
= 1+0.864
Window size = 1.864
Window size
= 2
The area that holds all the instructions the computer needs to start up when it is powered on is b) ROM
Further Explanation:
RAM and ROM are the types of memory. RAM is the active memory. The data can be read and written from RAM. While ROM is read only which meas that data or instructions on ROM cannot be changed.
The files or instructions that are needed to start up a computer are usually unchangeable as they always have to be the same. These type of instructions are stored in ROM. When he computer is turned on, the instructions needed to start the computer are loaded into the main memory from the ROM.
Hence, ROM is the correct answer.
