AP CSP Final Exam
What is the great reason behind why virtual records is represented in computers in binary? -
ANSIt's easier, inexpensive, and extra reliable to construct machines and gadgets that only
must distinguish between binary states.
What is the 4-bit binary quantity for the decimal wide variety Ten (10)? - ANS1010
What is the minimum number of bits you would want to encode the 26 letters of the alphabet
plus a area - a total of 27 characters? - ANS5 bits
Number systems with one of a kind bases such as binary (base-2), octal (base-eight), decimal
(base-10), and hexadecimal (base-16), are all used to view and constitute digital facts.
Which of the following is NOT actual about representing digital statistics? - ANSWhen records is
huge enough computers transfer to using decimal illustration rather than binary, because you
may constitute large numbers with fewer digits.
Consider the following 3 binary numbers:
01010
010000
1110
Which of the following lists the numbers so as from least to finest? - ANS01010
1110
010000
A middle faculty is increasing to open a high college subsequent yr, doubling the full variety of
college students. The school keeps a database in which each scholar's unique ID variety is
stored as an 8 bit number referred to as studentID. Before the arrival of the brand new college
students almost every eight bit variety has already been assigned to a pupil. Of the alternatives
supplied under, that's the smallest change to the manner studentID is represented essential to
make sure every incoming student gets a completely unique ID? - ANSAdd a chunk to
studentID to double the wide variety of IDs that the database can constitute.
A person clicks on a website, and it begins to load straight away, but it takes a long term to load
absolutely and pics seem slowly, separately. Which of the following is tested through this case?
- ANSLow bandwidth, low latency
, eight bits is sufficient to represent 256 one of a kind numbers. How many general bits do you
want to symbolize 512 (two times as many) numbers? - ANS9 bits
ASCII is a person-encoding scheme that makes use of a numeric price to represent each
character. For instance, the uppercase letter "G" is represented by way of the decimal (base 10)
price 71. A partial list of characters and their corresponding ASCII values are proven inside the
table underneath. (See Code.Org Unit 1 Ch 1 Assessment Question 9)
ASCII characters also can be represented by binary numbers. According to ASCII character
encoding, which of the following letters is represented through the eight-bit binary fee: 0100
0010 - ANSASCII Character: B
Two students have evolved a protocol in which they send four-bit messages to each other. They
determine to alter their protocol to begin sending 8-bit messages instead. How many greater
values may be represented in an 8-bit message than a four-bit message? - ANS2⁴ = sixteen
instances as many values
Which of the following statements are proper about routers and routing on the Internet. Choose
two solutions. - ANSA packet journeying between two computers on the Internet may be
rerouted typically along the way or maybe lost or "dropped".
Routers act independently and direction packets as they see suit.
The numerous protocols in use at the net are said to operate in layers in which the protocol(s) at
each layer remedy one trouble related to networked verbal exchange, and higher layers are built
on pinnacle of, and depend on, the lower layers to do their jobs.
From the listing provided pick out the two (2) answers that efficaciously describe which net
protocol is predicated on the alternative. For example: if protocol A is predicated on protocol B,
it way that A is a higher degree protocol than B, and as a consequence protocol B ought to exist
and work properly so as for protocol A to do its activity.
Select two solutions. - ANSHTTP is based on TCP/IP
DNS is based on TCP/IP
A school starts offevolved tracking which web sites each pc within the school is journeying with
the aid of tracking the packets leaving the college. A sample of the statistics they've
accumulated seems beneath:
IP Address Time URL
