1.0 Introduction Of Computer Network And Communication
A Computer network or data network is a telecommunications network that allows Computer to exchange data. In computer network, networked computing devices pass data to each other along data connections.The information could be stored on device,generated live outside the networkor could be generated by a process on another piece of information.The best-known computer network is the internet.A study of computer networks branches into many areas as we go up from fundamentals to the advanced levels.
2.0 Mobile Computing
Mobile computing is human-computer interaction by which a computer is expected to be transported during normal usage.Mobile computing involves mobile communication,mobile hardware, and mobile software.It may form a wireless personal network or a piconet.There are three different classes of mobile computing such a portable computers,Mobile phones and wearable computers.Many types of mobile computers have been introduced since the 1990s including the smartphone , tablet computer and ultra-mobile PC.

3.0 Internet Technology And Services
Voices over Internet Protocol (VoIP) is a methodology and group of technologies for the delivery of voice communication and multimedia sessions over Internet Protocol (IP) networks, such as the internet . VoIP converts anolog voice signals into digital data packets and supports real-time,two-way transmission of conversations using Internet Protocol (IP). In addiction to IP , VoIP uses the real-time protocol (RTP) to help ensure that packets get delivered in a timely way.Early providers of voice over IP services offered business models and technical solutions that mirrored the architecture of the legacy telephone network. Second-generation providers,such as skype.VoIP is available on many smartphones,personal computers and on internet access devices.Calls and SMS text Message may be sent over 3G OR Wi-Fi
A Blog (WEB LOG) is a discussion or information site published on the World Wide Web and consisting of discrete entries(post) typically displayed in reverse chronological order.Blog were usually the work of a single individual , occasionally of a small group, and often covered a single subject . Many blogs fuction as personal online diaries:others function more as online brand advertising of a particular individual or company. Allowing visitors to leave comments and even message each other is an important contribution to the popularity of many blogs.Most blogs are primarily textual,although some focus on art(art blogs) , photograpghs(photoblogs),videos(video blogs or “vlogs”),music (MP3 blogs) and audia(podcasts).
4.0 Types Of Network
A personal area network (PAN) is a computer network used for data transmission among devices such as computers , telephones and personal digital assistants. PAN are used for communication among the personal devices themselves(intrapersonal communication) or for connection to a higher level network and the internet. PAN can be constructed with cables or be wireless.You can use these networks to transfer files including email and calendar appointments.digital photos and music.
A virtual private network (VPN) extends a private network across a public network,such as the internet.It enables a computer to send and receive data across shared or public networks as if it is directly connected to the private network. A virtual private network connection across the internet is similar to a wide area network (WAN)link between sites.VPNs securely connect geographically disparate offices of an organization,creating one cohesive network.Besides that,VPN technology is also used by internet users to connect to proxy servers for the purpose of protecting personal identity and location.
A wireless local area network (WLAN) links two or more devices using some wireless distribution method and usually providing a connection through an access point to the wider internet.This gives users the ability to move around within a local coverage area and still be connected to the network.Most modern WLANs marketed under the Wi-Fi brand name.It have become popular in the home due to ease of installation and in commercial complexes offering wireless access to their customers:often for free.
Worldwide Interoperabilty For Microwave Access ( WiPAX) is a communications technology that uses radio spectrum to transmit tens of megabits per second in a bandwidth between digital devices such as laptop computers.The forum describes WiMAX as “a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL. Similar to WiFi, WiMAX brings with it the ability to transmit over far greater distances and to handle much more data
During the process of completing S07 assessment, I learned and obtained a lot of information about the current and future development in network and communication.with the types of network available nowdays,works can be done easier.With the Network that is getting better , Information can be found faster. I would like to thank my ICT teacher , which is Pn Khamdani , my friends and lastly my brother that helped and provided more information .
