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.

Businesses?

Title: SAN/NAS integrated storage system.

Today in all the corporate environment, the companies tend to either use SAN i.e.
Storage Area Network or NAS i.e. Network Attached Storage in order to store huge
mass of data.
Storage Area Network is defined as a specialized, higher speed network which aims
at providing block level network access to store data. SANs are majorly made of
hosts, switches, storage elements and many storage devices which are interlinked by
using several technology methods, topologies and protocols in any organization. SAN
is not easy to maintain and the cost involved in it is very high which cannot be easily
maintained by any small business organisations (Seagate, 2019).

On the contrary, Network Attached Storage is defined as one of the delicate storage
for file which helps several users and dissimilar client devices to extract required
data from a centralized disk capacity. In addition to this, users on LAN i.e. Local Area
Network access the shared storage with the help of a verified and standard Ethernet
connection. The devises related to NAS do not use any keyboard or display system
and they are typically managed and controlled by browser based utility. Every NAS
depends on the LAN and is denoted by a different and unique IP location.
Furthermore, it can also be noted that NAS works as private cloud in any company or
professional workplace. The advantages for such type of network is that it is faster,
not so expensive and serves all the advantages of a public cloud on site which
provides full control (Tanaka et al., 2007).
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.

CYBER Technology in Automation, Control, and Intelligent Systems (CYBER) (pp. 72-

Title: NTFS File System

There are different types of file which are widely used by modern operating system.
One of the majorly used file system is NTFS i.e. New Technology File System. NTFS is
a standard structure of file used by the windows NT operating system. The main aim
of such network is to extract and store huge mass of files on the hard disk.
Additionally, NTFS also announced several enhancements which include innovative
and modern structures of data which helps in increasing the performance, enhance
metadata and further add developments such as security access control, disk space
operation and file system journaling (Melton et al., 2017).
The NTFS swapped the OS/2 higher performance file system i.e. HPFS and the
Windows 95 file allocation table i.e. FAT which are commonly used in MS-DOS and
initial versions of Operating system. The innovative and modern advantage of NTFS
involves a fault tolerance system which itself repairs the error that take place in hard
drive without any error messages or information. NTFS also holds summarized
transaction records which aims at keeping the track record of error in hard drives.
Such quality is an advantage for improving files in case if hard drive damages and
avoids hard disk failures (Fisher, 2019).
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.
