INTRODUCTION:
SECTION 1: DICUSS THE BENEFITS AND CONSTRAINTS OF DIFFERENT NETWORK TYPES AND
STANDARDS:
1. Network
Definition: A network is a collection of computers, servers, mainframes, network devices,
peripherals, or other devices that are linked to facilitate data exchange. The Internet, which links
millions of people worldwide, is an example of a network. The image on the right shows an
example of a home network with many PCs and other network devices all connected.
2. Types of network:
2.1. MAN
Definition: A metropolitan area network (MAN) is a computer network that connects computers
within a metropolitan area, which can be a single large city, a collection of cities and towns, or
any given large area with multiple buildings. A MAN is larger than a LAN but smaller than a wide
area network (WAN)
Advantages:
• It can send data in both directions simultaneously
• It increases data transmission speed while improving data handling efficiency
• It allows for the cost-effective use of shared resources such as printers.
Disadvantages:
• These networks must be set up by knowledgeable technicians and network administrators.
• The deployment and administration expenses of this network are greater than those of a local
area network.
•This network is difficult to administer since it is comprised of several local area networks.
2.2. WAN
Definition: A wide area network (also known as WAN) is a big information network that is not
restricted to a single place. Through a WAN provider, WANs may permit communication,
information exchange, and much more between devices all over the world.
Advantages:
• Increase efficiency.
• Share information over a wide area.
• Protect your privacy.
