Computer network

Computer network technology The subject I will be undergoing in my next year will be Computer Network Technology BSc Hons. This subject looks at all aspects of computer networking in the modern world. This course also gives many computing principles such as systems analysis and database development. I have chosen this course because I have always been interested in computing and have made a few database systems while working in the army. I would like to learn more about network security and I hope

INTRODUCTION: The physical or network topology of a network seriously affects the network price, dependability, throughput, and approach pattern, etc, thus we want to contemplate these multiple criteria having totally different units, at the same time. However, normal ways of planning topology contemplate solely one criterion, e.g., minimizing the specified range of physical links. during this paper, we tend to propose a topology style methodology exploitation "average rank", that is calculated

interconnected through the internet nowadays. The internet is the connection of assorted computer networks through a series of service providers and businesses. In order to create these networks, there needs to be devices known as routers, switches and firewalls. These devices have some very well-known vendors, such as, Cisco and Juniper. Juniper uses an operating system called Junos. Junos OS is a great network operating system because of its modularity and it’s unique and hierarchical configuration

How to Define a Computer Network No matter how it is described or reported “computer network” continue being a difficult phrase to define. Computer IT technicians do not know how to approach to a regular person, and describe the operation of a simple computer networking . In the other hand, and this is also important, “regular normal” people seem not to care how important a computer network is, and what it really means. Maybe is because most of the time the computer network always is “behind the

Introduction Computer network security has never been as critical as it is today. The news is littered with the widespread incidents of hacking and cyber theft in the financial, entertainment, and retail industries, and more recently in our military. A recent survey, conducted by Kaspersky Lab, a leader in endpoint protection solutions, found that 94% of all companies surveyed experienced a cyber security issue (Kaspersky Lab, 2014). Furthermore, a recent study has found that the average cost of

not use the computer system to “snoop” or pry into the affairs of other users by unnecessarily reviewing their files and e-mail. Accessing other computers and networks: A User’s ability to connect to other computer systems through the network or by a modem does not imply a right to connect to those systems or to make use of those systems unless specifically authorized by the operators of those systems. Computer security: Each User is responsible for ensuring that use of outside computers and networks

Introduction Computer network - a system used to link PCs or computer equipment (servers, routers, and other equipment). For data transmission can be used various kinds of electric signals, light signals or electromagnetic radiation. Computer networks can be classified according to various criteria - territorial prevalence, type of network topology, etc. One of the criteria - the type of transmission, the network is divided into wired and wireless. Wi-Fi - a trademark of Wi-Fi Alliance for wireless

COMPUTER NETWORK ADMINISTRATOR A computer network (the "network") is the connection of at least two or more computers for the purpose of sharing data and resources. These resources can include printers, Internet access, file sharing, and electronic mail ("e-mail"). In today 's technological environment, most companies and businesses have some kind of network used on a daily basis. Thus, it is imperative to day-to-day operations that networks run smoothly. Companies employ at least one person

Computer Communications: Bus Network Bus Network, in computer science, a topology (configuration) for a local area network in which all nodes are connected to a main communications line (bus). On a bus network, each node monitors activity on the line. Messages are detected by all nodes but are accepted only by the node(s) to which they are addressed. Because a bus network relies on a common data "highway," a malfunctioning node simply ceases to communicate; it doesn't disrupt operation as
