Web 2.0:
Web that interacts with users
Semantic web/Web 3.0:

Main collection protocol:
The arrangement that is made about how computers can communicate. This is defined in the
protocols TCP/IP, which allows communication between computers on networks like the
internet.
Key issues that arise from this:
- Each computer with access to the internet must have a unique address (IP address)
- All providers of information on the internet need to be found through an address
(domain names – via Domain Name System)
- All information sent is divided into small packets of data, these must follow their own
route and go through many intermediate stations. Only after arrival the packets are
joined again.
e.g. a picture isn’t transmitted as a single image over the internet, but in many small
packets and through many routes.
Domain Name System:
System that converts illogical and hard-to-remember IP address numbers into recognizable
names.
Backbone:
Refers to national and international networks whereby local area networks can be linked. You
can say it’s the spine to which more linked networks are attached and by this they get access to
the internet. (e.g. highway)
LAN:
Local Area Network, a network that links computers and other devices connected to the
internet together inside companies. This way they can share printers, access to files etc.
Server:
A computer that provides data to other computers.

Peer-to-peer network (P2P):
Network based on equality of the various connected computers, each connected device can
connect data with any other device. There is no hierarchy in this system.
Bandwidth:
The amount of MB’s (data) that can be transported per unit of time.
Software:
Also called programming, is another word for computer programs. Apps are also
included under software. Software can be divided into two groups:
1. System software - Makes sure your device or network works
2. Applications software - Allows you to do certain tasks, writing texts, photo editing etc.
Key concepts of software types:
- Commercial software - Developed by a single person or company. Any software or program
that is designed and developed for licensing or sale to end users or that serves a
commercial purpose.
- Freeware and shareware - Forms of ndistribution and use of the software. With
freeware, the software is always free to use and with shareware sometimes you have
to pay for long or repeated use.
- Open-source software - The entire source code is freely available. The difference with
freeware is that with open source software the actual program code may also be modified
or improved by anyone.
-
- Cripple ware - The software is free but there are parts blocked or the functionality is limited.
For an additional fee you get the full package. The difference with freeware or shareware is
that the parts that are blocked are often essential.
- Malware - Malware is the generic term for malicious or damaging software such as viruses.
