Note: This document does not contain a complete
solution. You would need to elaborate within this document.
Include your name in
your file name and above.
You may use this document
to construct your answer, but it is only a guide. Since the key points to be described
are in this document, you may simply add your answers to it. Please submit your
answers in MS-word. The response to each question is expected to be one to two
pages in single spaced 11-12 point font. Drawings can be in Power Point, an
image file, or as a pdf document. They can be submitted as separate files, or embedded
in an MS word file.
Q1: Describe the major components of a desktop
or laptop personal computer that is not more than 3 years old. There should be four categories. Each
category has many components. Some components, such as the CPU could have sub-components.
A1: The
4 major computer components are listed below.
(A) Hardware Components:
· CPU: describe what the CPU is and describe its
3 major sub-components:
o
Sub-component
1
o
Sub-component
2
o
Sub-component
3
· Memory/storage: describe what memory/storage
is and describe the following major types:
o
RAM
o
ROM
o
Flash
o
Cache
o
DMA
o
Hard
disk drive (HD)
o
Solid
state drive (SSD)
· Other hardware components such as the monitor,
a keyboard, etc. No need to give a description of each subcomponent, just
provide a list of them.
(B) Software Components: describe each of the
following types of software components:
· OS
· Applications
· Drivers
· Utilities, system services
(C) Communication Components: describe each of
the following types of communication components:
· Communication Hardware components:
o
Layer 1:
e.g. twisted pair, copper cable, optical fiber, etc.
o
Layer 2:
e.g. Ehternet switch, WiFi switch, etc.
o
System,
devices: e.g. routers, gateway, GPS, cell phones
· Communication Software components:
o
Layer 2:
e.g. WiFi, Ethernet, DSL, Cable,
o
Layer 3:
IP
o
Layer 4:
TCP, UDP, etc.
o
Application
layer: HTTP, XML, SOAP, RPC, etc.
(D) Data Components: describe each of the
following types of data components:
· File system
· Data at rest
· Data in transition
· Types of media: e.g. voice, video, data, fax,
image, etc.
· Encryption, compression
· Data encoding: analog to digital (A/D),
digital to analog (D/A)
Q2: Draw
the layout of the following components: CPU, cache, ROM, RAM, DMA, and I/O
modules. Use the line to show the interaction between every two components. For
example there is a line between the CPU and cache and another line between the CPU
and ROM. You can’t draw a line in the middle with all components hanging from
the line. No other components should be included in this answer. No need to
provide any additional descriptions.
A2: Below
is a drawing of the components. You need to draw a line between any two
components that share an interface. Your response can be embedded in your MS
Word document or submitted as a separate file.
You can copy and paste the drawing into a PPT file and add the lines
for the interfaces. Or, you could copy and paste it into image editing software
such as Photoshop and edit it. Another approach is to print it out, manually
add lines to it, and then take a photo and submit it as an image file.
Interfaces hints:
· The CPU has an interface to all components up
to the I/O modules, but not to individual I/O devices.
· The I/O modules are where the software
interacts with the I/O devices.
· The CPU moves data to/from RAM and the I/O
modules.
· The CPU moves data from ROM.
· Only the CPU has access to Cache.
· DMA moves data to/from the I/O modules and to/from
RAM.
