Components of Information Systems
✓ Hardware is a set of devices such as
processor, monitor, keyboard, and
printer.
✓ Software is a set of programs that
enable the hardware to process data.
✓ Database is a collection of related files,
tables, relations, and so on, that stores
data.
✓ Network is a connecting system that
permits the sharing of resources
between computers.
✓ Procedures are the set of instructions
about how to combine the above
components.
✓ People are those individuals who work
with the system or use its output.

5. What is a computer network
▪ A network is a way to get “stuff” between 2 or more “things”
• Examples: Mail, phone system, conversations, railroad system, highways and roads.
▪ Computer Network is a connecting system that permits the sharing of resources between
computers.
6. Computer Networking Models
▪ Models, also called protocol stacks, represented in layers, help to
understand where things go right or wrong.
• Open Systems Interconnection (OSI) Model.
• Transmission Control Protocol/Internet Protocol (TCP/IP) Model
9. Network Topologies
▪ A topology is a way of “laying out” the network. Topologies can be either
physical or logical. There are different types of computer network
topologies. Each topology has its benefits and drawbacks
17. Introduction to Mobile Communication
▪ Marconi invented the wireless telegraph in 1896
▪ Communication by encoding alphanumeric character sin analog signal
• Sent telegraphic signals across the Atlantic Ocean
▪ Communications satellites launched in 1960s
• could only handle 240 voice circuits.
▪ • Advances in wireless technology
• Radio, television, mobile telephone, communication satellites
▪ More recently
• Satellite communications, wireless networking, cellular technology.
20. Network Security
▪ Every individual and organization should ensure maximum security of network and IT infrastructure
▪ Some guidance on Network Security
• Controlling access, ensuring all the users should not get the same access in every available network drive.
• Integrating some critical software like Antivirus.
• Ensuring the security of the specific deployed application.
• The analytical result of specific behaviour.
• Preventing any kind of critical data loss.
• Providing require security in any email communication.
• Firewall protection
22. Network security
▪ Network security is
protection of the access
to files and directories in
a computer network
against hacking, misuse
and unauthorized
changes to the system
