Technology and information technology in particular, can now provide help in many ways that were not possible in the past. However, as more and more information and business and personal transactions are delivered or managed online, so it is increasingly important to ensure that users are not disadvantaged by the technology. Indeed, there is legislation that now requires organizations to provide both physical and virtual access so that no special needs group is disadvantaged.
Yourproject should be a response to one of theissuesidentified on the next page, and should take advantage of some of your design and technical skills and should help a specific group or organization, for example, by raising awareness, increasing membership or activity, raising funds, or providing services, developing new products or interfaces, or training programs for users or their supporters or some combination of these. Interfaces to computer programs, or other IT tools are areas where there are many opportunities for small projects. It may also be possible for you to consider ways of developing these or exploiting new technological developments such as mobile computing, wireless communication, digital imaging, new media, or electronic business processes in appropriate ways. You should develop an application or website prototype that will allow users to benefit from your project.
You are invited to propose a project that will help a small organization, group of users, or people who support your users. For example, there are a large number of organizations that provide support or advice to people, attached to local or national health, educational or community establishments. You will need to do some research on your chosen organization or user group, but you are not required or expected to contact them directly.
One of the project criteria is to decide the scope of the project. You may decide to limit your project to a specific local organization, a specific group of users, or a national organization. You must identify a specific area where such a project development would be useful and feasible and justify your choice.
You are required to submit a Project Proposal and Project Initiation Document (PID). You will get feedback on your initial proposals during the sessions during the taught module, and you will then be expected to work these up into a full Project Plan, with illustrative supporting material. In addition to your PID, you will be asked to submit a small “look and feel” prototype or walkthrough, and slides for boardroom presentation that describe the business case for your deliverables.
Any proposal will need to be constrained within a small budget for startup funds and development costs of a nominal (virtual) £100K. It is expected that theproject, will be up and running within 6 months, and result in some sustainable benefit to the chosen users or organization within one year. It is expected that these startup funds, possibly with further funds from other identified sources, will enable any new long-term venture to become self-supporting after an initial period of up to 12 months. If you decide that your project will require additional funding beyond the £100K, you will need to show how this money might be raised and spent, and how it could be recovered over a two-year period. You can apply for further funding.
(a) Changing UK demographics
“The population of the UK is ageing. Over the last 25 years the percentage of the population aged 65 and over increased. This trend is projected to continue. By 2034, 23 per cent of the population is projected to be aged 65 and over compared to 18 per cent aged under 16. The fastest population increase has been in the number of those aged 85 and over.
As people get older, many suffer from impairment in sensory, cognitive or motor skills – for example, from impaired hearing and vision, reduced dexterity or cognitive abilities, dementia or Alzheimer, and many other medical or psychological conditions that require specific support. In the current economic climate, a growing elderly population is also likely to experience, social isolation, and reduced access to local shops, libraries, health and social services.
(b) Graduate employment opportunities
In 2018-2019 there were 2.38 million students studying at UK higher education institutions, following a steady increase over the past decade. Identify a project to help these graduates find appropriate employment.
(e) Brexit
Will there be a smooth transition for the UK economy after Brexit. Will Brexit create the next UK recession or is there a way of benefiting from this and creating a time of prosperity for the UK. Could you develop some ideas to help the economy grow over the next few years.
(f) Student research funding and scholarships. Identify a project to create funding opportunities to carry out research at universities taking into consideration venture capitalists and innovative ideas.
(g) Volunteering and charity work – you may have further ideas which you are free to suggest
(h) Economic Recovery projects post COVID pandemic – Identify a project to get the nations economy back on track

Lists. Trace the following c++ program showing all output in the order that it appears on the output device (presumably the screen). If anything happens that makes it impossible to accomplish an operation or the results of doing so are unpredictable, describe what happens and abort at that point.
For this program assume that the following functions (methods) are fully defined and implemnted in the appropriate header and implementation files for the List class.
– construct that creates an empty list
– empty that returns true if the list is empty, false otherwise
– insert (a,b) that inserts an integer a into the list at position b
– erase(a) that removes the integer at position a in the list
– overloading the output operator << to enable it to display all elements of a list in sequence so cout< – overloading the assignment operator so assigning one list to another creates a deep copy of the list. CODE BELOW #include
using namespace std;
#include “List.h”
int main(void)

There are 4 parts for the project. The question may be long to read but it’s not a heavy work because there are many examples and explanations for the each parts.
*Part 1. The first part of this project requires that you implement a class that will be used to simulate a disk drive. The disk drive will have numberofblocks many blocks where each block has blocksize many bytes. The interface for the class Sdisk should include :
Class Sdisk
{
public :
Sdisk(string diskname, int numberofblocks, int blocksize);
int getblock(int blocknumber, string& buffer);
int putblock(int blocknumber, string buffer);
int getnumberofblocks(); // accessor function
int getblocksize(); // accessor function
private :
string diskname; // file name of software-disk
int numberofblocks; // number of blocks on disk
int blocksize; // block size in bytes
};
An explanation of the member functions follows :
-figure 0 (what I attached below)
IMPLEMENTATION GUIDELINES : It is essential that your software satisfies the specifications. These will be the only functions (in your system) which physically access the Sdisk. NOTE that you must also write drivers to test and demonstrate your program.
*Part 2. The second part of this project requires that you implement a simple file system. In particular, you are going to write the software which which will handle dynamic file management. This part of the project will require you to implement the class Filesys along with member functions. In the description below, FAT refers to the File Allocation Table and ROOT refers to the Root Directory. The interface for the class should include :
Class Filesys: public Sdisk
{
Public :
Filesys(string diskname, int numberofblocks, int blocksize);
int fsclose();
int fssynch();
int newfile(string file);
int rmfile(string file);
int getfirstblock(string file);
int addblock(string file, string block);
int delblock(string file, int blocknumber);
int readblock(string file, int blocknumber, string& buffer);
int writeblock(string file, int blocknumber, string buffer);
int nextblock(string file, int blocknumber);
Private :
int rootsize; // maximum number of entries in ROOT
int fatsize; // number of blocks occupied by FAT
vector filename; // filenames in ROOT
vector firstblock; // firstblocks in ROOT
vector fat; // FAT
};
An explanation of the member functions follows :
-figure 1 (what I attached below)
-figure 2 (what I attached below)
The FAT is an array of block numbers indexed one entry for every block. Every file in the file system is made up of blocks, and the component blocks are maintained as linked lists within the FAT. FAT[0], the entry for the first block of the FAT, is used as a pointer to the first free (unused) block in the file system. Consider the following FAT for a file system with 16 blocks.
-figure 3 (what I attached below)
*Part 3. The third part of this project requires that you implement a simple shell that uses your file system. This part of the project will require you to implement the class Shell along with member functions. The interface for the class should include :
class Shell: public Filesys
{
Public :
Shell(string filename, int blocksize, int numberofblocks);
int dir();// lists all files
int add(string file);// add a new file using input from the keyboard
int del(string file);// deletes the file
int type(string file);//lists the contents of file
int copy(string file1, string file2);//copies file1 to file2
};
An explanation of the member functions follows :
IMPLEMENTATION GUIDELINES :
See the figure 4 (what I attached below) for the ls function of Filesys.
See the figure 5 (what I attached below) for dir function of Shell.
See the figure 6 (what I attached below) for main program of Shell.
*Part 4. In this part of the project, you are going to create a database system with a single table which uses the file system from Project II. The input file will consist of records associated with Art History. The data file you will use as input consists of records with the following format: The data (180 records) is in date.txt file (what I attached below)
In the data file, an asterisk is also used to delimit each field and the last character of each record is an asterisk. The width of any record is never greater than 120 bytes. Therefore you can block the data accordingly. This part of the project will require you to implement the following class:
Class Table : Public Filesys
{
Public :
Table(string diskname,int blocksize,int numberofblocks, string flatfile, string indexfile);
int Build_Table(string input_file);
int Search(string value);
Private :
string flatfile;
string indexfile;
int IndexSearch(string value);
};
The member functions are specified as follows :
See the figure 7 (what I attached below) for the main program of Shell which includes a search command.
The vast majority of the population associates Blockchain with cryptocurrency Bitcoin; however, there are many other uses of blockchain; such as Litecoin, Ether, and other currencies. In this discussion, please describe at least two cryptocurrencies with applicable examples. Discuss some similarities and differences. Lastly, discuss if you have any experience using any cryptocurrencies.
Please make your initial post and two response posts substantive. A substantive post will do at least two of the following:
At least one scholarly source should be used in the initial discussion thread. Be sure to use information from your readings and other sources from the UC Library. Use proper citations and references in your post.
Find a peer-reviewed scholarly journal article discussing electronic innovation and the government. Complete a review of the article by writing a 4-page overview of the article. This will be a detailed summary of the journal article, including concepts discussed and findings. Additionally, find one other source (it does not have to be a peer-reviewed journal article) that substantiates the findings in the article you are reviewing.
System architecture is the descriptive representation of the system’s component functions and the communication flows between those components.
My definition immediately raises some important questions.
• What are “components”?
• Which functions are relevant?
• What is a communication flow?
