If you have any further questions, don’t hesitate to get in touch.

Computer networks

What is a computer network?

A computer network is a group of computers – and potentially other hardware – that have been connected together for the purpose of sharing resources. One of the most common is Local Area Network, or LAN. Computer networks allow employees to:

  • Communicate via email, video calls, instant messaging and more
  • Share files across the network
  • Collaborate on work projects
  • Share devices such as printers, photocopiers and scanners
  • What are the benefits of a computer network?

    There are many benefits of having a computer network, including:
  • Increased security if the network is properly secured
  • Lower costs via shared internet connection and software applications
  • Resource sharing for copiers, printers and scanners
  • What is network security?

    Network security is concerned with protecting files and directories in a computer network against hacking, misuse and unauthorised changes to the system. This includes:
  • ID and password management
  • Firewalls
  • Encryption of confidential data
  • Backing-up confidential data
  • Regular reviews of the performance of internal systems
  • Cyber security and computer viruses

    What is cyber security?

    Cyber security is the protection of IT equipment – including computers, programs and data – from virtual theft and damage. It manages hardware, software and information, protecting them from any malicious activity.

    What is a computer virus?

    A computer virus is a type of malicious software program that can seriously disrupt an organisation’s IT. In turn, it can lead to loss of data, disruption to work and reputational damage. Viruses enter by attaching themselves to programs, files or documents, lying dormant before executing their malicious code when a certain action is performed. This means viruses can lie undetected for some time.

    What are the different types of computer virus?

    There are many types of computer virus that users need to look out for. Ten of the worst types include:
  • Web scripting virus
  • Boot sector virus
  • Polymorphic virus
  • File infector
  • Macro virus
  • Browser hijacker
  • Direct action virus
  • Multipartite virus
  • Fat virus
  • Memory resident virus
  • What does a computer virus do?

    A computer virus will attach itself to a software program in your computer and will likely damage programs, delete files, slow the performance of your computer down or reformat the hard drive. Viruses can have serious implications for organisations so it’s crucial you take steps to protect your IT suite

    What should I do if my computer has a virus?

    If your computer has a virus, you should:
  • Back up any important files on your computer
  • Disconnect from the internet
  • Delete any temporary files
  • Download malware scanners
  • Run a scan
  • If happy, restart your computer
  • If you suspect something serious has happened, contact your IT department or your managed IT provider.


    What is virtualisation?

    Virtualisation is the process of creating a virtual version of something, rather than an actual, physical version. Examples of virtualisation systems are virtual computer hardware platforms, storage devices, and computer network resources. Things that can be virtualised include memory, desktop infrastructure, storage and networks.

    What are the benefits of virtualisation?

    The main benefit of virtualisation is the ability to run multiple operating systems on one physical server, reducing costs and lengthening hardware refresh cycles. Fewer server and storage resources mean that virtualisation is more environmentally friendly, and it can also help with disaster recovery.

    Wireless networks

    What is a wireless network?

    A wireless network is a network of computers that makes use of wireless data connections between network points. Wireless networks are not configured using wires, allowing for devices to stay connected even when roaming.

    IT outsourcing & managed services

    What is IT outsourcing?

    IT outsourcing is when a business employs a third party – such as TechBrain – to take responsibility for the management of part or all of their IT, usually for cost or efficiency reasons. Such services typically include:
  • Help desk support
  • On-site support
  • Network administration
  • IT consulting and strategy
  • Why outsource IT?

    Outsourcing IT can help you to:
  • Reduce costs
  • Improve operational efficiency
  • Free up time so key individuals can focus on customers and generating revenue
  • Keep up-to-date with the latest technology
  • How much does IT support cost?

    The cost of IT support depends on the type of support package you take out, but IT support providers typically charge by the hour (usually starting from around $120), or charge a fixed price per month based on the number of devices supported. Some IT providers over-promise yet under-deliver when it comes to IT provisions, so it’s important that cost is a consideration when reviewing your IT support.

    Why is IT support important?

    IT support is critical for all organisations. It helps companies to:
  • Operate efficiently
  • Maximise productivity
  • Reduce costs
  • Improve physical and virtual security
  • Who needs IT support?

    Any organisation that relies on IT to operate needs to invest in maintaining and updating their IT so that they operate efficiently. When individuals do not have the skills to do this in-house, they are advised to outsource to an organisation that is made up of experienced and well-trained professionals. These professionals can ensure that the organisation’s productivity is high and IT environment is low risk in terms of viruses and cyber attacks.
