You need to design a data storage scheme for Hayseed Heaven library data system. There are several hundred thousand large data r

ecords. You expect frequent insertions/deletions as well as frequent queries, involving multiple attributes. There is no requirement for printing the file in order. You may assume the initial file is available sorted. The queries are in real time and primarily occur on the ISBN number, title, and author fields. There are occasional queries on the publisher and subject fields of the record. You may make reasonable assumptions about hardware availability. The entire system is archived monthly. What do you propose and why

Answer:

Make use of hash tables

Explanation:

The appropriate thing to use for this should be a hash table.

A Hash Table can be described as a data structure which stores data in an associative manner. In a hash table, data is stored in an array format, where each data value has its own unique index value. Access of data becomes very fast if we know the index of the desired data. So we can perform Hashing on ISBN Number since its unique and based on the Hash Function w ecan store the Information record.

There is no requirement for printing the file in order - HashTables dont store the data in order of insertions, so no problems with that

It becomes a data structure in which insertion and search operations are very fast irrespective of the size of the data. So Querying books details can be fast and searching will take less time.

It can also be pointed out that it wont be too expensive for Hardware implemtation as HashTables stores data based on Hash Functions and memory consumption is also optimal which reduces memory wastages.

Answer:

The algorithm:

Input days

sum = 0

for i = 1 to days

   input text

   sum = sum + text

end for

average = sum/days

print average

The program in pascal:

var days, sum, text, i:integer;

var average : real;

Begin

    write ('Days: '); readln(days);

    sum:=0;

    for i := 1 to days do begin

         write ('Text: ');  readln(text);  

         sum:=sum+text;

    end;

    average := (sum/days);

    writeln ('The average text is' , average);

End.

Explanation:

This declares all variables

var days, sum, text, i:integer;

var average : real;

This begins the program

Begin

This gets the number of days from the user

    write ('Days: '); readln(days);

Initialize sum to 0

    sum:=0;

This iterates through the days

    for i := 1 to days do begin

This gets the text for each day

         write ('Text: ');   readln(text);  

This sums up the texts

         sum:=sum+text;

End loop

    end;

Calculate average

    average := (sum/days);

Print average

    writeln ('The average text is' , average);

End program

End.

What are the modes of operation of WLANs?
Nimfa-mama [501]

Answer:

WLAN's or Wireless LAN Units have 2 main modes of operation

Explanation:

The Two Main modes of Operation are the following

<u>Infrastructure Mode:</u> in this mode the main WLAN unit becomes the main connection point in which all devices are connected to and the main unit provides an internet connection to all the devices connected to it.

<u>Ad Hoc Mode:</u> in this mode devices transfer data from one another back and forth without permission from a base unit.

Some WLAN units will also include 2 extra modes of operation called Bridge and Wireless Distribution System (WDS).

<u>Bridge Mode:</u> this mode allows the base unit to act as an intermediary and bridge two different connection points. Such as bridging a wired connection with a wireless one.

<u>WDS Mode:</u> this mode uses various access points to wirelessly interconnect devices to the internet using repeaters to transmit connections. It can provide internet to both wired and wireless clients.
