Implementing a WLAN in a school would require several user groups. These could include: Students Teachers Support Staff (i.e. Councilors) Administration Network Administration In a school environment‚ there are several risks that need to be taken into account. Being wireless in nature‚ it opens up more avenues for an unauthorized person or hacker to access the network as they do not need to be physically connected to the network‚ just be in the vicinity. Users would have to be careful to safeguard

There are a few problems I would anticipate with using this combination of protocols. The first is if there is some sort of failure with the delivery of the sequence of data packets. As UDP is connectionless there isn’t a reliable order that the packets will arrive‚ one would assume this is why they are using stop and wait‚ to try and compensate for this issue. As a result‚ you may get some packets timing out and being resent by the server causing duplicate packets to be sent‚ all while awaiting

History of computing hardware The history of computing hardware is the record of the constant drive to make computer hardware faster‚ cheaper‚ and store more data. Before the development of the general-purpose computer‚ most calculations were done by humans. Tools to help humans calculate were then called "calculating machines"‚ by proprietary names‚ or even as they are now‚ calculators. It was those humans who used the machines who were then called computers; there are pictures of enormous rooms

A hardware description language(HDL) is a language from a class of computer languages‚ specification languages‚ or modeling languages for formal description and design of electronic circuits‚ and most-commonly‚ digital logic. It can describe the circuit’s operation‚ it’s design and organization‚ to verify its operation by simulation. The hardware description language looks much like a programming language such as C++‚ it is a textual description consisting of expressions‚ statements and control

Triple DES uses three individual keys with 56 bits each. The total key length adds up to 168 bits‚ but experts would argue that 112-bits in key strength is more like it. Despite slowly being phased out‚ Triple DES still manages to make a dependable hardware encryption solution for financial services and other industries. 2. RSA RSA is a public-key encryption algorithm and the standard for encrypting data sent over the internet. It also happens to be one of the
