1. Wireless LAN: Wireless LAN (WLAN) stands for wireless local area network also referred as LAWN. LAWN stands for local area wireless network, is one in which user can connect to a local area network through a wireless connection using radio signals. This LAN provides wireless communication over a short distance area using radio or infrared signals. This can be build using any different wireless network protocols, most commonly either Wi-Fi or Bluetooth. The pros and cons of wireless LAN is as following
in Pakistan: Wireless networks are computer networks that does not uses cable/wire but work with wireless data connection between network nodes. Wireless network play an important role in education system of Pakistan. Wireless networking use radio waves instead of wires. For Example: cell phone networks, WLAN, laptop to internet etc are wireless networks. Wireless technology makes our life easy; it is no doubt if we say that it occupying
attackers. It is also a tool of hacker to break into, steal or destroy your computer. Spyware is a kind of software that is specifically designed to infect your computer and spy on you. Spam is incredibly annoying when you're bombarded with emails and ads that you have no interest in whatsoever (Jessica Drew 2014). 2. Computer hacking situation. Computer are becoming more and more useful in our activities. Nowadays almost people has this modern device and internet connection. Student need computer for
combine in an ad hoc manner within the pervasive network. As such, trust models must be developed in order to ensure tighter security. Other disadvantages of pervasive computing include frequent line connections that are broken, slow connections, very expensive operating costs, host bandwidths that are limited in nature and location-dependent data. All of these instances can impede the security of pervasive computing because they result in multiple system vulnerabilities. One more disadvantages is that

programming, the central unit will act on certain circuits related power signals picked up by the field elements concerned. [2] 2.5. Advantages and Disadvantages. Here, in this chapter, advantages and disadvantages will be defined. Let's start with advantages first. Next will be exposed the main of them: a) Energy saving: It is the biggest advantage, because when you can program all the devices you do not need to be spending all day. This is seen especially in the heating system
________________________________________ 1.1 DISTRIBUTED COMPUTING Distributed computing is a field of computer science that studies distributed systems. A distributed system consists of multiple autonomous computers that communicate through a computer network. The computers interact with each other in order to achieve a common goal. A computer program that runs in a distributed system is called a distributed program, and distributed programming is the process of writing such programs. Distributed computing
