6. Computer viruses and
their effects
Viruses, worms and Trojans are software programs that have been written by individuals to disrupt or interfere
with your computer files.
Viruses – Programs that can corrupt your software programs, disrupting the way they work—even how
your computer functions
Worms – Specific types of viruses that spread copies of themselves to other computer systems
(usually via network connections). Unlike “typical” viruses, worms do not generally infest your programs or
operating systems, but greatly increase network or web traffic as they spread.
Trojans – Specific types of viruses that seem harmless but can damage your computer files
(like the mythical Trojan Horse). Unlike a “true” virus, Trojans can't reproduce themselves, nor can they
infect your programs.

10. Understanding a Small Business Network
Solution
A small business network solution from HI-TECH provides a secure foundation that consists of switches,
routers, and HI-TECH services
Network switches connect multiple devices, including computers and printers, on the same network.
The design makes it easy to add applications to your network without major upgrades. They keep your
small business computer network accessible and secure.
You can also add voice and conferencing technologies to a our small business network solution to
enhance collaboration, reduce communications costs, simplify messaging, and more.

11. CAMPUS NETWORK
Whatever their size or security needs, enterprises today can enjoy the benefits of a
virtualized campus network with many closed user groups, all on a single physical
network.
As the demands placed on campus networks have grown in complexity, so has the need
for scalable solutions to separate groups of network users and resources into logical
partitions
Virtualization of the network provides multiple solutions for centralizing
services and security policies while preserving the high-availability, manageability,
security, and scalability benefits of the existing campus design.
To be effective, these solutions must address the three primary aspects of network virtualization; access
control, path isolation, and services edge.
Challenge:
Varying levels of access privileges within an enterprise
Regulatory compliance
Network simplification for very large enterprises
Network consolidation

12. Vertical
Manufacturing:-
Production plants (robots, automation of production environment, and so on), administration, sales, video
surveillance.
Finance:-
Trading floors, administration, mergers.
Government :-
Shared buildings and facilities supporting different departments. In some countries the law mandates
separate networks between such departments.
Healthcare :-
General trend toward hotel service with medical treatment. Separation among medical staff, magnetic
resonance imaging (MRI) and other technical equipment, Internet access for patients, media services such
as radio and television for patients. and other technical equipment, Internet access for patients, media
services such as radio and television for patients.
Commercial Real Estate:-
Multi-business Campus Some resources are shared among groups. Multiple companies on the same
campus where different buildings belong to different groups, but all rely on the same core and Internet
access. Building automation is administered by the owner and spans across all buildings.

13. Retail :-
Kiosks, public wireless LAN (PWLAN) in branches, RF identification,
WLAN devices (for example, older WLAN barcode readers that do not
support any WLAN security).

14. LARGE OFFICE
A large office design is one step closer to a campus design.
In addition to supporting more users, a large office might also need higher LAN switching capability if
supporting a server farm (DMZ).
Support for some of these services requires the use of appliance devices if higher throughput is required.
To meet these requirements, a distribution layeris added to the small office or medium office topology by
introducing a Layer 2/Layer 3 switch to provide the required LAN switching capabilities, port density, and
flexibility to support additional appliances.

15. The Design should also consider.
Overview:
Voice, data, video network infrastructure cabling. (I.e. Security alerts and
surveillance, CCTV and CATV)
Security:
Don’t forget security !!
Cooling:
Network and server equipment create abundant heat and also tend to shutdown when over-heated.
Wireless:
The wireless standard that you select should depend on whether you’re running a thin or fat client.
Fiber Backbone:
Fiber backbones can create options for high bandwidth & long cabling distances between office locations
at rates that are quite competitive.
Scability& Availability:
The design has to be highly Scalable & should also ensure zero down time.

16. MULTIPLE BRANCH CONNECTIVITY
Based on the number of users in the branch, three design models can be used, each ofwhich offers a
certain amount of scalability.
The choice of models is affected by requirements such as high availability, because some of the interfaces
on the edge router do not support Ether Channels.
If a server farm must be supported in the branch, the design must support the required port density to
connect the small server farms and to meet the additional DMZ requirements.
High availability, scalability, and advanced services add to the cost of the infrastructure. Layer 2 and Layer
3 switches do provide some alternatives to which software images can be used to keep the cost low while
still providing high availability and scalability.
Also, the infrastructure can be reused to migrate to advanced services if required without having to
redesign.
The requirement are different for different-sized branch offices. Based on the discussions above, the
following lists the basis for LAN design at the branches:
Number of users ,Cost High, availability ,Scalability Security
