Week 1
The text discusses examples of traditional mass storage such as magnetic disk and
solid-state drives. While these still underpin most mass storage, in corporate
environments they are often accessed via Network Attached Storage (NAS) or Storage
Area Network (SAN) technologies. Find and summarise ONE resource that describes
EITHER NAS or SAN storage technologies. The resource, and your summary, must
focus on either NAS or SAN, NOT BOTH.
Title and Reference:
Chosen topic: Network Attached Storage (NAS)
Bednarz, A. (2019). What is a SAN and how does it differ from NAS?. [online] Network
World. Available at: https://www.networkworld.com/article/3256312/what-is-a-san-and-

from-nas.html
Summary:
This resource provides a detailed description of Storage Area Network (SAN) which
helps in providing block level network access to storage. The resource also helps in
understanding that there are different components of SAN such as storage elements,
storage devices, switches and hosts. The resources also helps in understanding the
wide range of topologies, protocols and technologies. The resources also provides in-
depth discussion about the usage of the SAN and most of the associated switches. The
reason behind selecting this resource is it provides a detailed explanation of the use of
this service in commercial establishment. This resource also helps in understanding the
wide range of protocols which are considered in SAN such as the Fibre Channel, Hyper
SCSI and the Ethernet. The working principles of SAN is the key point of this SAN. The
other key information which was mentioned in this resources is the association of the
SAN fabric with SAN. The association with the Fibre Channel switching technology with
SAN is written in this paper in a detailed manner. The resource was very much useful
to understand the tape libraries and disk based services. It can be said that SAN is very
much beneficial to understand how each server associated with SAN gets access to
the shared devices. The role of the SAN volume controller was also stated in the paper
in a professional manner.

Week 2
Operating systems use file managers to interact with mass storage devices.
However, the way in which data is stored and retrieved is dictated by the file system.
There are many types of file systems used by modern operating systems. Find and
summarise ONE resource that describes ONE such file system that is NOT FAT,
FAT32 or ExFAT. The resource, and your summary, must focus on A SINGLE file
system.
Title and Reference:
Chosen topic: New Technology File System
TechRepublic. (2019). News, Tips, and Advice for Technology Professionals -
TechRepublic. [online] Available at: https://www.techrepublic.com/article/file-
systems-101-ntfs/ [Accessed 29 May 2019].

Summary:
This resource is about the New Technology File System which are increasingly used
in storing and retrieving of the files on a hard disk. The use of NTFS is very much
useful to keep the track of the file clusters. It can be said that the information about a
file cluster can be retrieved in a useful manner using a NTFS. The main reason
behind selecting this resources is it helps in identifying the advanced specifications of
the NTFS. The resources also stated that more than 16 billion bytes in size can also
be accessed from NTFS. The main point of discussion of this paper is it helps
identifying the file compression ability of NTFS. The resources also stated that long
file names are supported by NTFS. The resources was also very much useful to
understand the data security provided by NTFS on both the fixed as well as the
removable disks. The main point of discussion of this resource is the detailed
description of the Master File Table (MFT). This resource helps in understanding the
usefulness of the NTFS in terms of efficiency and storage. The other key information
of this resource is it helps in identifying different qualities of NTFS such as scalability
issues, journaling issues, transactions, and encryption techniques, reparse points
and interoperability. The resources was very much important to understand each of
the internal as well as the external features of NTFS such as ability of managing
metafiles and file compression abilities of NFTS.

Week 3
The National Broadband Network (NBN) is currently being rolled-out across Australia
and there is a mix of technologies that are being used to deliver Internet services (for
example, FTTN, FTTC, FTTP, HFC, fixed wireless and satellite). Find and
summarise ONE resource that describes ONE of these delivery technologies. The
resource, and your summary, must focus on A SINGLE technology.

Code, Security and Server Stuff. (2019). Telstra promised Fibre to the house (FTTP)
when I had FTTN and this is what happened.. [online] Available at:

Summary:
Chosen topic: FTTN
This resources is about the usefulness of FTTN which are widely used in most of the
global commercial establishments such as Telstra can be understood from this
resource. The resource can be very much useful to understand the usability of FTTN.
The usefulness of the FTTN by the consumers of Telstra Corporation was discussed
in this resource in an organized manner. The reliability of the FTN was discussed in a
detailed manner in this resource. The limitation of the FTTN was discussed in this
resource as well. This resources was very much useful to understand and identify the
advantages as well as the limitation of FTTN. The key point of discussion of this
resources is the download speed of FTTN. Based on the discussion of this paper it
can be said that the download speed of FTTM is decreasing each day. The main
point of discussion of this paper is the detailed conversation between a consumers of
Telstra with an operator of Telstar.
The other key information which can be identified from this resources is the
advantages as well as the benefits of using FTTN. The resources highlight that the
upload speed of FTTN is 400Mbps and the download speed of FTTN is 1000 Mbps.
The resources were very much useful to understand that the installation of the FTTN
usually takes day to one week time.
