  we set up a static IP for the server, then added the DHCP service to it, we set up the start IP address on each exit node, we set the IP setting to DHCP, and it automatically assigned each node its own IP we added a default gateway IP (being the server's IP), allowing us access the "web" from the computers in the network the HTTP automatically worked DNS - Domain name system the domain name system translates domain names such as google.com to its IP address, this is needed as websites are found using IP addresses and not their domain name DHCP - dynamic host configuration protocol DHCP automatically assigns network parameters such as IP, and the default gateway to computers within the network HTTP - hyper-text transfer protocol HTTP is a set of rules for sending and receiving data between the client and server

Details The Digital Strategy is a cross-government strategy which sets out a coherent articulation of the government’s ambitious agenda for digital policy. The strategy focuses on 6 key areas: Digital foundations: an update on the Plan for Digital Regulation and the supply-side offer to the digital economy. This includes a focus on: digital infrastructure, data, regulation and digital markets, and security. Ideas and intellectual property: consolidation of the government’s work to support the innovation ecosystem, including in universities and the private sector. This builds on the Innovation Strategy with a specific focus on digital technology. Digital skills and talent: highlights the UK government’s work to reform and improve our skills and talent provision for the digital economy. This includes: strengthening the digital education pipeline, increasing awareness of the pathways into digital occupations, work to develop an enhanced digital skills base, growing people’s ...

 The impact of unsafe or inappropriate use of digital technology and mitigation techniques to reduce impact Psychological impacts Cyber bullying bullying that happens online, through any method of online communication, and include sending personal embarrassing info, being rude/mean, sending threats, etc cyber bullying can harm the online reputation of a person, it is... permanent - as stuff posted online is permanently put onto the internet, the effect on a persons reputation can be permanent, and affect the rest of their lives hard to notice - people may not overhear the bullying as it is online persistent - due to the easy access we have to the internet, cyber bullies can reach people almost 24/7 form the safety of their own home emotional impacts - cyber bullying can lead victims to feel humiliated, isolated angry, and powerless due to vulnerabilities that the bully may expose, among other reasons mental health impacts - cyber bullying can lead to anxiety, depression, low self e...

Physical impacts Posture Back pain is usually due to poor postures when using digital tech, smartphones and computers are used consistently every day putting unnecessary strain on the muscles and ligaments of the spine and neck. people using devices tend to hunch their shoulders, this creates bad posture and leads to nerve pain, headaches, and arthritis, especially as people use computers for many hours in a day Eye strain CVS (computer vision syndrome) is the term used for people such as office workers who spend long periods of time in front of the computer, CVS includes headaches difficulties with focusing itchy, burning watery eyes, dry eyes, double/ blurred vision sensitivity to light Repetitive strain injury RSI is pain felt in the nerves, muscles and tendons caused by repetitive movement and overuse (eg OSU! players), it can affect the forearms, elbows, wrists, hands, neck, and shoulders Display screen equipment (DSE) workstation checklist (hse.gov.uk)

Networks MAC : medium access control PAN: personal area network WAN: wide area network LAN: local area network MAN: metropolitan area network - across a town Network typologies a physical topology is the physical arrangement of nodes/end points/hosts/clients/devices in a network, a logical topology defines how the devices communicate across the physical topology A network wired in star topology can behave logically as a bus network by using a bus protocol and appropriate physical switching (though you probably should not do this) Switch vs hub Switch: faster, more reliable, and more secure data, uses "access tables" to isolate each connected nodes location Hub: connected nodes are not isolated, so all traffic goes to all nodes, slower, less secure and less reliable STAR vs MESH star: all nodes connected to a central node, usually a switch, these are fast, reliable and cheaper, with good security, however have one critical point a failure, meaning if the switch breaks, the ne...

  Switching is the process where data is transferred from one device to another Packet switching is connectionless, this means no session or channel is established prior when transferring data each packet gets split up and sent to the destination independently, they take different paths so they will not arrive in the correct order once the packets have reached their destination, they will be reassemble in correct order, 

1. Discuss physicological impacts of cyber bullying Cyber bullying can affect people in many different ways, depending on the person, they may just not pay attention to it, while others may be deeply affected by it, causing them physicological stress, depression, anxiety, and in some cases can cause eating disorders, self harm, and suicidal thoughts 2. Explain how the unsafe or inappropriate use of digital technology can cause a reduction in physical activity If an individual overuses technology, then this can reduce the amount of physical activity they do as they spent less time outside in general, this can lead to many health problems such as obesity, general poor health, etc. 3. Describe how digital technology in the bedroom can disrupt sleep patterns Most digital display screens emit blue light, this tricks our brains into thinking it is day time, say we stay awake for longer 4. Explain how digital technology can impact society through changing behaviors use of digital technology c...
