About types of network topology

-



  • Bus Topology –  It is defined by the use of a single main cable which has terminators on both ends. All the other nodes like workstations, peripherals, etc. are connected to this main cable. This type of topology is widely implemented in LANs as it is easy to install and does not cost much. It also does not require much cabling as in the case of some other topologies like star and mesh. The main disadvantage of this topology is that the entire network is dependent on the main cable. In case some problem occurs in the main cable, the whole system gets affected.

  • Star Topology – It is named as star topology as it looks similar to a star whereas all the elements of the network are primarily connected to a central device. This central device is known as hub and can be either of a hub, router or a switch. This central hub also works as a repeater for data flow. A point-to-point connection is laid between the devices and the central hub. Thus, all nodes are connected to each other only by the assistance of this central hub. Installation and wiring is easy of star topology. The functioning of the entire system depends on the central hub.

  • Ring Topology – It is in a shape similar to a ring, in which every node is connected to only two neighbors. The messages move in only one and the same direction in this arrangement. In case any cable or device breaks away from the loop, then it can be a fatal problem for the entire network. Token ring technology is used to implement this type of topology. It can be used for handling high volume of data. All devices are given the same importance in this topology. In case the capacity is increased beyond its comfortable limit then the network starts to compromise on speed.

DATA BACKUP  A  data backup  is the result of copying or archiving files and folders for the purpose of being able to restore them in case of data loss. Data loss can be caused by many things ranging from computer viruses to hardware failures to file corruption to fire, flood, or theft (etc). If you are responsible for business data, a loss may involve critical financial, customer, and company data. If the data is on a personal computer, you could lose financial data and other key files, pictures, music, etc that would be hard to replace. As part of a data backup plan, you should consider the following: What data (files and folders) to backup What compression method to use How often to run your backups What type of backups to run* What kind of media on which to store the backups Where to store the backup data for safekeeping 2. Cryptography Cryptography includes techniques such as microdots, merging words with images, and other ways to hide

DO YOU KNOW ABOUT INTRANET? Intranet Intranet is defined as private network of computers within an organization with its own server and firewall. Moreover we can define Intranet as: Intranet is system in which multiple PCs are networked to be connected to each other. PCs in intranet are not available to the world outside of the intranet. Usually each company or organization has their own Intranet network and members/employees of that company can access the computers in their intranet. Every computer in internet is identified by a unique IP address. Each computer in Intranet is also identified by a IP Address, which is unique among the computers in that Intranet.

A computer security risk is any action that could cause a loss of or damage to computer hardware, software, data, information, or processing capability. types of security risk s ; (a) Malware :       Malware is malicious software, which are programs that act without a user’s knowledge and deliberately /purposely  alter the computer’s operations. Types of Malware : *Computer viruses :  A potentially damaging program that affects, or infects a computer or mobile device negatively by altering the way the computer or device works without the user's knowledge or permission *Worms : P rogram that copies itself repeatedly, for example in memory, using up resources and possibly shutting down the computer, device or network. * Trojan Horses : P rogram that hides within or looks like a legitimate program.  Unlike a virus or worm, a trojan horse does not replicate itself to other computers or device.   (b )  Hardware Theft  poses les
