Purchasing software network licenses is relatively appear in purchasing individual licenses.
More Productivity
Shared Internet access means no one needs to wait to use the Internet or email.
Increased access to communication channels
You can communicate with others in the network using the email or Instant Messenger software.
More Efficient Patching of Software
Software updates needs only be installed once.
DISADVANTAGES OF COMPUTER NETWORK
Network Failure
Some of the organization's activities depend on the network to be up and running.
Server Failure
Server faults may prevent you from using some application, some from accessing your computer.
Hacker Prone
Your system is open to hackers, especially if it is connected to the Internet at all times.
Prone to Virus
Network are vulnerable to virus attack. A virus introduced in one work station can spread.
Location/Distance Problems
Resources, such as printer, might be located too far from your table.
TYPES OF MEDIA NETWORK
WIRED NETWORK
- is a common type of wired configuration. Most wired networks use Ethernet cables to transfer data between connected PCs. In a small wired network, a single router may be used to connect all the computers. Larger networks often involve multiple routers or switches that connect to each other.
WIRELESS NETWORK
- is a network set up by using radio signal frequency to communicate among computers and other network devices. Sometimes it's also referred to as WiFi network or LAN. This network is getting popular nowadays due to easy to setup feature and no cabling involved.

- PAN ( Personal Area Network )
- LAN (Local Area Network )
- MAN ( Metropolitan Area Network)
- WAN ( Wide Area Network )
- PAN ( Personal Area Network ) - is a computer network for interconnecting devices centered on an individual person's work space. A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants.
- LAN ( Local Area Network ) - is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LAN's over any distance via telephone lines and radio waves.
- MAN ( Metropolitan Area Network ) - is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).
- WAN ( Wide Area Network ) - is a communications network that spans a large geographic area such as across cities, states, or countries. They can be private to connect parts of a business or they can be more public to connect smaller networks together.
