Different ways to store data

 Different ways data can be stored 

 

Data can be stored in many ways, the key ones being: 

  • USB – A USB stores data using a flash memory, which means the ones and zeros of your data are stored on transistors.  


Pros: 

    • Inexpensive 
    • Easy to use 
    • Portable  

  • Don’t require an internet connection 


Cons: 

    • As it’s physical, could be lost 
    • Connectivity – A single person can use a USB at a time 

 

  • Solid state drive – A solid state drive (SSD) stores data permanently inside an integrated circuit, typically using flash memory. Although USB’s use flash memory, SSD’s provide a more advanced version designed to handle the daily demands of computers.  


Pros: 

    • SSD’s are faster than hard drives 
    • Power and energy efficient, this is as it has no moving parts. 
    • Durable 

 

Cons: 

    • Expensive  
    • Slow 
    • Limited storage

    • Tape Drive – These are not typically used as much in the modern world, yet they were definitely popular in the past. The data on a tape drive is stored on a magnetic tape. A tape drive records data on a loop of flexible celluloid like material that can be read and erased. 

 

Pros: 

    • Cheap 
    • Durable 
    • Energy-efficient 
    • More scalable 

Cons: 

    • Slow 
    • Old 
    • Not random access (like hard drives for example) 

 

 

  • DVD – Data is stored on the disk in the form of microscopic data pits and lands. The pits are etched into a reflective layer of recording material.  

 

Pros: 

    • Large storage capacity 
    • Portable 
    • High data stability 

 

Cons: 

    • Tough to vary data 
    • There is no single standard on DVD 
    • It uses digital compression

Topologies

 Topologies What is a network topology? A network topology is the arrangement of the elements, such as links and nodes, of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks and computer networks.  Network topology examples Point to point topology -      This is arguably the most basic topology as it only consists of 2 nodes and a connection between them. So for example, if you were to configure a router in London, to connect and use resources on a network in Manchester, you would want to make sure that you had a link between them that supports your needs.  Star topology - A star topology is a centralised topology consisting of multiple nodes and a central hub/switch. It is also a design where all devices are connected to a central hub or switch, and messages are passed to the central core that, in turn, passes the

Emerging technologies allowing adaptability and future proofing

  Emerging technologies allowing adaptability and future proofing Machine Learning Machine Learning is a field of study in artificial intelligence concerned with the development and study of statistical algorithms that can learn from data and generalise to unseen data, and thus perform tasks without explicit instructions. Advances in the field of deep learning have allowed neural networks to surpass many previous approaches in performance.   Artificial Intelligence (AI) Artificial Intelligence is a set of technologies that enable computers to perform a variety of advanced functions, including the ability to see, understand and translate spoken and written language, analyse data, make recommendations and more.   Internet of things (IoT) The internet of things refers to a network of physical devices, appliances and other physical objects that are embedded with sensors, software and netw...
