WPAN ( wireless personal area network )

Explanation:

a.PAN ( personal area network )

This network is limited to the work place of a single person. Hence, the name given as personal area network. The devices connected by PAN belong to the range supported by the technology used to implemented the personal area network.

The devices present in this type of work place are connected to each other through PAN. PAN can connect computer, mobile and other technological devices which support PAN.

The data is transferred among these devices through PAN.

Both wireless and wired networks can be used to implement PAN. Wired PAN is achieved by using USB. Wireless PAN uses various technologies which are discussed below.

b.WPAN ( wireless personal area network )

The wireless PAN covers only short distance and hence requires low power.

The distance can range from few centimetres to few meters.

IEEE 802 has described the technologies and standards for each type of network. This network is implemented mainly by technologies such as Bluetooth, wireless USB, IrDA.

1.Bluetooth uses radio waves of short waves. Devices like keyboard, mobile phones, personal digital assistant ( PDA ) use this technology to communicate.

WPAN implemented using Bluetooth is known as piconet. It can connect up to 8 devices. Among them, one is the master device while rest devices become the slaves.

The range of such a network varies from 10 meters to 100 meters.

2.IrDA stands for Infrared Data Association. This technology uses infrared light. Examples using this technology include printers and scanners.

Plugging in

i.Devices supporting WPAN can only communicate with each other when they are within the supported range or distance from each other.

ii.In addition, these devices should have the capability to block devices which will cause unnecessary interference or are not authorized to gain information.

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
