Explain how arrays are stored in memory? Show how arr [5] is stored in the memory. Assume each memory location is one byte long
Black_prince [1.1K]

Explanation:

Array is collection of similar data types it is a linear data structure.Array stores elements in a contiguous memory location.

We have an array arr[5]  of size 5 and it is of integer type.Suppose the starting address of the array is 2000 and each memory location is one byte long.As we know that the size of integer is 2 or 4 bytes we take it 2 bytes.

If the starting address is 2000 that is of index 0 then the address of index 1 is 2000+2=2002.

address of index 2=2004.

address of index 3=2006.

address of index 4=2008.

Since size of int is 2 bytes hence we add two memory location.

suppose one packet switches between a sending host and a receiving host. the transmission rates between the sending host and the
ICE Princess25 [194]

The total end-to-end delay to send the packet length is L/R1 + L/R2. When using store-and-forward packet switches, the end-to-end delay is calculated as d = N × L/R.

<h3>How can you determine a packet's end-to-end delay?</h3>
  • When using store-and-forward packet switches, the end-to-end delay for sending a single packet of length L across N connections, each with a transmission rate R, is d = N × L/R. (Queuing, propagation delay, and processing time are all ignored).
  • The amount of time it takes a packet to travel from source to destination across a network is known as one-way delay (OWD).
  • It is a term that is commonly used in IP network monitoring. It differs from round-trip time (RTT) in that it only measures the journey from source to destination in one direction.
  • Propagation delay is the amount of time it takes for one bit to travel from the sender to the receiver end of a link.
  • Propagation delay is defined mathematically as the distance between sender and receiver. Propagation delay ∝ 1 / transmission speed.

About n processes are time-sharing the CPU, each requiring T ms of CPU time to complete. The context switching overhead is S ms.
Genrish500 [490]

Answer:

(a) Q = (M-(1-n)S)/n

(b)    

When M = 450,

       Q = 82

       % CPU time wasted = 8.889%

When M = 90,

       Q = 10

       % CPU time wasted = 44.44%

When M = 50,

       Q = 2

       % CPU time wasted = 80%

Explanation:

Given  Data:

n = process

T = ms time

Context switch time overhead = S

and M is total overhead

See attached file for the calculation.
