1)
less repeted code -- code can be writen once and used many times
allows for recursion -- subroutines can call themselfs
creates more maintainable code -- allows for only 1 point to be changed to edit the whole program
2)
avoid un-reputable websites
use https only
keep backups so systems with viruses can be wiped without lossing anything
don't click on links in emails
3)
protocol -- http
domain name -- loveapug.org.uk
4)
it can be slow to query
duplicate data takes up extra space
5)
it is faster to run
it provides lower level hardware access
6)
the set real numbers
7)
no side effects or global state meaning any server can run a function to get the same output
because everything is a function, a program can be executed accross many servers at once
8)
NO
9)
lifetime
packet id
10)
the data can be checked if it matches the checksum, which can tell the system if there was an error in transmition. It will be calculated from the data on the senders side, and will be attached to the packet
11)
sjeydchdj
12)
the key must be the same length as the input, the key must not repeat
13)
2
14)
all the lines of data are sent using a shared clock, and are recvied at the same time
15)
bt: O(log n)
bs: O(n^2)
ls: 0(n)
ms: O(nlog n)
16)
sending many lines of data at once, to achieve a faster speed
17)
you only need 1 wire
18)
B
19)
to tell the other end of the signal to start reading data
20)
to tell the other end of the signal to stop reading data
21)
to manage system reasores
to provide a simple programming interface for programmers
22)
