IPv4 is the main TCP/IP protocol in the internetwork layer of the TCP/IP reference model. It supports a connectionless service between hosts in an interne

4.3 Programming and abstraction

In the early 1990s programming an application for the internet was a tough proposition. I remember that I once had an application which required a very simple form of communication with another application located at a remote computer. I used a technology known as Winsocks which required me to carry out some pretty arcane code development just to send a simple test message to another computer and to receive a reply from that computer.

As noted in the Introduction, much of the debate about difference and diversity in health and social care has focused on issues of ‘race’ and ethnicity. It is perhaps the area that first comes to mind when there is discussion about issues of communication and difference in care services, but it is also an area where the arguments are most complex and contentious.

As you saw in Section 1, ‘racial’ or ethnic diversity has often been constructed as a ‘problem’ for health and so

In our society we tend to expect not to have to face the likelihood of death until our 70s at least, but one group of people who are having to face the prospect of death at a relatively young age are those diagnosed as HIV-positive. Controversy surrounds the issue of whether those at risk of contracting the virus should have the blood test which might give them that death sentence. At the time of writing there is no clear evidence that any treatment can improve the prognosis, even if taken at
