foremost, a business spread across different Regions would run effectively
through a network topology. A network topology
is the arrangement of a network, including its nodes and connecting
lines. There are two ways of defining network geometry: the physical topology
and the logical (or signal) topology. The physical topology of a network is the
actual geometric layout of workstations. There are several common physical
topologies, as described below and as shown in the illustration.
The key to
fast and efficient telecommunications is networks. Effy Oz states that in the
context of data communications, a network is a combination of devices (at least
two computers) connected to each other through one of the communication
channels called multiplexers.
For a business with multiple offices in different towns and
provinces (regions), it would be recommended to create a networking
infrastructure such as a Wide Area Network (WAN). This network crosses
organizational boundries and reaches outside the immediate environment. WANs
can be private or public. The internet is widely known as an example of a
public WAN, whilst private LAN may use dedicated lines. It is a known fact that
many organizations cannot afford to maintain the private LAN. Value-added
networks (VANs) such as Tymnet and Sprintnet provide enhanced network services
such as protocol conversion and error detection and correction. This type of
network fulfils the organizational needs for reliable data communications while
relieving the organization of providing its own network management and
enhancement. Wide area network protocols are significantly more complex than

The technologies involved in communication tend to be
complex. You certainly don’t need to understand them for your ICT course.
However, there are aspects of digital communications that you need to be aware
of. These relate primarily to the two types of network and the ways of connecting to
the internet. Let’s look at these two briefly:
Internal networks –
Usually referred to as a local area network (LAN),
this involves linking a number of hardware items (input and output devices plus
computer processing) together within an office or building. The aim of a LAN is
to be able to share hardware facilities such as printers or scanners,
software applications and data. This type of network is invaluable in the
office environment where colleagues need to have access to common data or
programmes. Organisations even take it further by saving more money by
investing in one central printing machine which can like a number of computers
and laptops as opposed to
External networks – Often you need to communicate with someone outside your internal network,
in this case you will need to be part of a wide area network (WAN). The
internet is the ultimate WAN – it is a vast network of networks.
ICT is categorized
in four components necessary for business. These four components are as
Telecommunication infrastructure such as telephone lines, wireless and satellite
Computer technology such as hardware and software.
Content infrastructure, where information can be collected, stored and made
Human Intervention to store, retrieve and manipulate information.
These joined together are recognized as components of an
In my organization, ICT is used in a form of telephones,
cellular phones, Microsoft Outlook for sending and receiving emails, scheduling
of meetings and setting up reminders for meetings. Systems such as SAP to
manage finances and human resources related matter, i.e. capturing data in real
time. Usage of media platforms such as Twitter and facebook is used in my organization
to log customer queries and updates, and also to keep customers abreast about
services offered and also how to access those services.
That said, I would recommend the Wide Area Networks as it
will enable various offices to access and share information without hindering
any service delivery. There will no delayed communication as information will
be shared instantly.
