1. Give one reason why data is represented in binary in a computer [1]
2. How many bits in a byte? [1]
3. How many bytes are there in a MB? Include your working.
Answer:
1) Computers use voltages and since voltages changes often, no specific voltage is set for each number in the decimal system. For this reason, binary is measured as a two-state system i.e. on or off. Also, to keep calculations simple and convert into binary online, computers use the binary number system
2) 8 bits
3) 1000000 bytes

Create an 80x86 program that define an array of doubleword numbers then read two values, first one indicates how many actual numbers will be in the array, and an integer n. The program should display all of the numbers in the array that are greater than the number n.
The program requires user to read a specified number of values beyond a set limit from a given array. The program which performs this task is written in python 3 thus :
from random import randint
#import the randomint module
import random
#import the random module
double_list = [randint(11, 99) for p in range(0, 10)]
#randomly selects a list of 10 double integer values
def rand_num(lis, n_values , n):
#initialize a function named rand_num which takes in 3 parameters
filter = [val for val in lis if val > n]
#filters the variables to contain those only greater than the specified limit
arr_ = random.sample(filter, n_values)
#using the sample function, select the stated number of values from the filtered list
return arr_
#return the selected values
n_values = int(input('Enter number of values : '))
#prompts user for the length of array
n = int(input('Enter limit : '))
#prompts user for the limit of the values to be included in the array
print(rand_num(double_list, n_values, n))
#A sample run of the program is given and output attached.

Answer:
50,000 seconds
Explanation:
First multiply 500GB into 1000.(*1GB is equal to 1000MB so were going to multiply it so that we can get the exact MB) and we will get 500,000 MB. Then let's divide it by 10.(*since 10MB can be transfer in just one second.) and we will get 50,000 SECONDS.

Why is it important to know the measurement of the component of the computer?
what is the full meaning of the following acronyms:ARPANET, BOOTP, GSM, GUI, EOM, EULA, CTSS.
Answer:
ARPANET: Advanced Research Projects Agency Network
BOOTP: Bootstrap Protocol
GSM: Global System for Mobiles
GUI: graphical user interface
EOM: Enterprise Output Management
EULA: end-user license agreement
CTSS: The Compatible Time Sharing System
Explanation:
BEFORE GOING FOWARD KNOW THAT I DO NOT OWN THESE TEXTS.
GSM= a standard developed by the European Telecommunications Standards Institute to describe the protocols for second-generation digital cellular networks used by mobile devices such as mobile phones and tablets.
ARPANET=the first public packet-switched computer network. It was first used in 1969 and finally decommissioned in 1989. ... Many of the protocols used by computer networks today were developed for ARPANET, and it is considered the forerunner of the modern internet.
BOOTP= is an internet protocol that lets a network user automatically be configured to receive an IP address and have an operating system booted without user involvement.
GUI= A graphics-based operating system interface that uses icons, menus and a mouse (to click on the icon or pull down the menus) to manage interaction with the system.
EOM= refers to the process by which enterprise organizations manage, format and distribute data created from operational applications.
EULA= An end-user license agreement (EULA) is a license that gives a user the right to use a software application in some manner. EULAs are designed to enforce specific software use limitations, such as only using the software on one computer.
CTSS=services for children who require varying therapeutic and rehabilitative levels of intervention to address conditions of mental illness or emotional disturbance that impair and interfere with development and functioning. overcome deficits or maladaptive skills acquired over the course of a psychiatric illness.

We have noted that there can be no input queuing if the switching fabric is n times faster than the input line rates, assuming n input lines all have the same rate. Explain why this is the case.
Consider the given data:
Assume packet length=n
Maximum queuing delay= (n–1)D
All packets are of the same length, n packets arrive at the same time to the n input ports, and all n packets want to be forwarded to different output ports.
a) The maximum delay for a packet for the memory = (n-1)D
b) The maximum delay for a packet for the bus = (n-1)D
c) The maximum delay for a packet for the crossbar switching fabrics= 0

The program which would help Eva convert a Lisp file into machine code by interpreting only a single line of code at a time is: A. interpreters
Interpreters can be defined as computer software programs that are designed to translate (interpret) a programming language (code) into machine code, especially by interpreting only a single line of code at a time.
Hence, an interpreter executes the instructions that are written in a programming language (code) one after the other (instruction by instruction), before it translate (interpret) the next line of code.
On the other hand, a compiler takes the entire program (code) and interprets them.
In conclusion, an interpreter can help Eva convert a Lisp file into machine code by interpreting only a single line of code at a time.

What is short lists?Every camera shot that needs to be recorded in a scene for a video production is listed in detail on a shot list.
A shot list, created by the director and cinematographer during pre-production, is a thorough list of each shot that must be taken on a particular shoot day. Its main objective is to deconstruct a scene into detailed phases that can be used as a guide for your day of shooting.
A shot list is a breakdown of each shot of each scene and the order in which you plan to shoot them, whereas a storyboard shows your cinematographer and production designer your vision for each specific scene.
