each incoming student receives a unique ID? - (answer)Add a bit to pccID to double the number
of IDs that the database can represent.
Number systems with different bases such as binary (base-2) and decimal (base-10) are all used
to view and represent digital data.
Which of the following is NOT true about representing digital data? - (answer)Some large
numbers cannot be represented in binary and can only be represented in decimal.
Which of the following RGB values represent the color below? (Magenta) - (answer)255, 0, 255
A computer program uses 4 bits to represent nonnegative integers. Which of the following
statements describe a possible result when the program uses this number representation?
I. The operation 4 + 8 will result in an overflow error.
II. The operation 7 + 10 will result in an overflow error.
III. The operation 12 + 3 will result in an overflow error. - (answer)II only
,Which of the following explains a benefit of using open standards and protocols for Internet
communication? - (answer)Open standards and protocols allow different manufacturers and
developers to build hardware and software that can communicate with hardware and software on
the rest of the network.
Which of the following is a true statement about Internet communication? - (answer)Every
device connected to the Internet is assigned an Internet protocol (IP) address.
A computer program uses 5 bits to represent nonnegative integers. Which of the following
statements describe a possible result when the program uses this number representation?
I. The operation 10 + 8 will result in an overflow error.
II. The operation 16 * 2 will result in an overflow error.
III. The operation 20 + 18 will result in an overflow error. - (answer)II and III only
The following figures represent different ways of configuring a network of physically linked
computers labeled P, Q, R, and S. A line between two computers indicates that the computers can
communicate directly with each other. In which configuration is it NOT possible to have
redundant routing between computers P and S? - (answer)The one that has a single path going
from P to R to Q to S
, Which of the following statements are true about routers and routing on the Internet. Choose two
answers. - (answer)Routers act independently and route packets as they see fit.
A packet traveling between two computers on the Internet may be rerouted many times along the
way or even lost or "dropped".
