Describe the three essential components of a computer that make up the Von Neumann architecture.
How do these components work together to produce a machine that can be programmed to complete
different tasks? (COME BACK TO THIS QUESTION) - CORRECT ANSWER-Input/Output devices
allow the user to communicate with the computer by entering commands and then viewing the results.
In what units are CPU speeds measured, and what does this measurement unit refer to? If one
computer has a 2GHz Celeron processor and another has a 2GHz AMD Athlon processor, does that imply
they will be able to execute the same program in the same amount of time? Explain. - CORRECT
,ANSWER-CPU speed is generally measured in gigahertz (GHz), which indicates how many billions of
basic instructions a CPU can execute in a second.
TRUE or FALSE? In order to be classified as a "computer," a device must have a keyboard and display
screen? - CORRECT ANSWER-False
TRUE or FALSE? A bus is a collection of wires that carry information as electrical signals between the
hardware components of a computer. - CORRECT ANSWER-True
TRUE or FALSE? A bit is a unit of data that corresponds to one of two potential values (commonly
written as 0 and 1). - CORRECT ANSWER-True
TRUE or FALSE? A kilobyte of storage is 2^10 = 1,024 bytes, where a byte is a collection of 8 bits. -
CORRECT ANSWER-True
TRUE or FALSE? A hard drive is classified as volatile memory, because it requires a constant power
supply in order to retain its information. - CORRECT ANSWER-False. Only RAM and Cache are.
TRUE or FALSE? Keyboards and mice are examples of computer input devices. - CORRECT ANSWER-
True
TRUE or FALSE? A directory is a collection of files that are organized together and labeled with a
common name. - CORRECT ANSWER-True
TRUE or FALSE? The World Wide Web was developed in the early 1970s, shortly after the creation of the
Internet. - CORRECT ANSWER-False
TRUE or FALSE? A Web browser is an example of applications software. - CORRECT ANSWER-True
Describe the difference between hardware and software and identify two examples of each. - CORRECT
ANSWER-Hardware -- refers to the physical components of the computer
example: the monitor, keyboard, hard drive, etc.
, Software -- refers to the programs that execute (i.e.,run) on the computer
example: carrying out tasks such as word processing or accessing the Web, Windows, Mac OS
Memory
stores information for the computer to process, as well as programs, or instructions specifying the steps
necessary to complete specific tasks.
Central Processing Unit (CPU)
is the component that carries out programmatic steps in order to process data.
Modern computers integrate several different types of memory, such as cache, RAM, hard drive, and
flash drive. Why are different types of memory used, as opposed to the exclusive use of a particular
technology? What would be the drawbacks, for example, of using only cache memory, or only hard
drive? - CORRECT ANSWER-Different types of memory are used because they have different
characteristics which have different benefits.
RAM and Cache are expensive and volatile. However, they are very fast and are good to use when you
need to pull up things quickly.
Hard drive is slow compared to RAM and Cache, however, it is inexpensive and not volatile, so it can be
used by people with various backgrounds. It is good to store things that you don't really need to pull up
Computer memory is usually grouped in bytes, which consist of 8 bits each. How many different values
can be represented using a byte? How many different values can be represented using two bytes? -
CORRECT ANSWER-One byte (8 bits) can represent 256 different values. Two bytes (16 bits) can
represent 65,536 different values.
The Intel Core i9 is an example of a processor, or CPU, as are the Intel i5 and AMD Ryzen 7. List the two
main tasks that the CPU performs in controlling the computer's workings and provide a short
explanation of each. - CORRECT ANSWER-The CPU is responsible for two key tasks:
(1) fetching program instructions from memory, and (2) executing those instructions.
