Abstract

Currently, Mobile phone and desktops are becoming more and more advanced day by day. These systems provide wide variety of multimedia application. Multimedia communication system should provide good quality of service. Multimedia includes continuous data such as audio, video and discrete data such as text, graphics. The challenge of multimedia communication system is to deal with this continuous and discrete data over digital network. The elements as well as types of multimedia networks used in multimedia system are described in this paper.

Abstract

IEEE 802.11ac standard introduces gigabit data rates to 802.11 wireless networking. The maximum data rates with 802.11ac will be ten times faster than with the 802.11n standard. Among the wireless technologies for 2.4GHz and 5GHz unlicensed bands, WiFi has significantly transformed our networking culture at home, office, and public places to the extent that its presence has become a necessity. On the other hand, such presence has transformed adjacent technologies like cellular communications and smart grid by its off-loading capacity and low-power capability respectively. To fulfill the new demands, IEEE and the WiFi industry are delivering the 802.11ac that has astonishing maximum raw data rate of 6.9Gbps with the fairest techniques to coexist with other users of the unlicensed band. These data rates will significantly enhance Wi-Fi usages such as wireless display and sync-and-go. In this paper we mentioned analysis of 802.11ac and its techniques.

Abstract

To accommodate the information security growth and hacker's improved strategies and tools, intrusion detection systems (IDSs) are required to be allocated across the network. Organizations require security systems that are flexible and adaptable in order to combat increasing threats from software vulnerabilities, virus attacks and other malicious code, in addition to internal attacks. To meet organizational objectives and requirements the intrusion detection systems must be effective. This paper gives an overview of Intrusion Detection Systems ability to detect the intrusions in computer systems after a thorough comparative theoretical study. Different security threats are made on the networks and are caused by the intruders who either misuse the assigned privileges or access the systems via internet. Paper also highlights the mechanism of data recovery from corrupted processes, which can be incorporated in any Intrusion detection system.
