Simple IT & AI Knowledge for Small Businesses

IT support helps businesses keep their computers, software, email, internet, printers and networks working properly. It can include fixing technical problems, setting up new devices, improving Wi-Fi, supporting Microsoft 365, helping with security and giving advice before buying new technology.

A server is a computer or system that provides services to other devices in a business. It may store files, run business software, manage users, host databases or help staff access shared resources. Some businesses use physical servers in the office, while others use cloud-based services instead.

Cloud storage allows files to be stored online instead of only on one computer. Services such as OneDrive, SharePoint and Google Drive help staff access files from different devices, share documents and reduce the risk of losing data if a laptop is damaged or replaced.

A business network connects computers, printers, phones, servers and other devices so they can communicate with each other and access the internet. A good network helps staff work efficiently, share resources and stay connected securely.

The internet is the external service that connects your business to websites, email and cloud services. Wi-Fi is the wireless connection inside your building that allows devices to connect to your router or network. You can have working Wi-Fi but poor internet, or good internet service but weak Wi-Fi coverage.

Microsoft 365 is a cloud-based business productivity platform that includes tools such as Outlook, Word, Excel, Teams, OneDrive and SharePoint. It helps businesses manage email, documents, meetings, collaboration and file storage in one connected system.

Business email uses your company domain, such as yourname@yourbusiness.co.uk, which looks more professional and builds trust. It also gives better control over users, security, access, backups and company data compared with personal email accounts.

OneDrive is mainly for personal work files. SharePoint is used for shared company files and team document libraries. Teams is used for messaging, meetings and collaboration. Together, they help businesses store, share and work on documents securely.

Use strong passwords, enable multi-factor authentication, avoid clicking suspicious links, check sender addresses carefully, do not open unexpected attachments and report phishing emails. Businesses should also review mailbox access and remove accounts that are no longer needed.

Phishing is a scam where criminals send fake emails, messages or websites to trick people into sharing passwords, bank details or business information. Phishing messages often look urgent and may pretend to be from banks, suppliers, Microsoft, delivery companies or senior managers.

Multi-factor authentication, also called MFA, adds an extra security step when logging in. For example, after entering a password, the user may need to approve a sign-in on a phone app or enter a code. MFA makes it harder for attackers to access accounts even if a password is stolen.

Weak passwords are easier for attackers to guess or steal. Strong passwords should be long, unique and not reused across different services. Businesses should consider using a password manager and enabling MFA on important accounts.

Look for unusual sender addresses, poor spelling, unexpected attachments, urgent requests, payment changes, login links and messages asking for passwords. If unsure, do not click the link. Contact the sender using a known phone number or email address.

Cyber Essentials is a UK security framework that helps businesses improve basic cyber protection. Readiness means reviewing areas such as firewalls, secure settings, access control, malware protection and software updates before applying for certification or improving internal security.

Backups protect your business from data loss caused by accidental deletion, device failure, cyber attacks, theft or damage. A good backup plan helps restore important files and reduces downtime when something goes wrong.

Cloud backup stores data online with a backup provider, while local backup stores data on a physical device such as an external drive or local server. Many businesses use both for extra protection. Cloud backup is useful for recovery from theft, fire or hardware failure.

Stop using the device or folder where possible, check recycle bin or version history, check cloud backup, and avoid overwriting data. If the files are important, ask an IT professional before attempting recovery.

Only collect the data you need, keep it secure, restrict access, delete it when no longer needed and avoid sharing personal information unnecessarily. Staff should understand how to handle customer and business data safely.

AI, or artificial intelligence, refers to software that can assist with tasks such as writing, summarising, analysing information, answering questions, creating ideas and automating repetitive work. AI can support productivity, but it should be used carefully with human review.

Small businesses can use AI to draft emails, summarise documents, create marketing ideas, prepare checklists, improve customer service scripts and organise information. However, staff should check accuracy and avoid entering confidential or sensitive data into tools that are not approved.

AI can help write professional emails, improve grammar, summarise long documents, create FAQs, draft customer replies and prepare meeting notes. It can save time, but final responses should always be reviewed by a person before sending.

Do not share passwords, bank details, private customer data, medical information, confidential contracts, internal security details or sensitive business information unless your business has approved the tool and understands how the data is handled.

AI can make mistakes, misunderstand context or produce information that sounds correct but is inaccurate. Human review helps ensure the final output is accurate, appropriate, professional and safe to use.

New laptops usually offer the latest warranty, battery life and performance. Refurbished laptops can be more cost-effective and suitable for many business tasks if they are properly checked before supply. The best option depends on workload, budget, warranty needs and expected lifespan.

Consider processor, memory, storage, warranty, operating system, screen size, ports, security features and whether the device is suitable for your business software. For business use, avoid choosing only by the lowest price.

Servers, switches, routers and access points should be chosen based on business size, users, security needs, applications and future growth. Poorly selected equipment can cause slow performance, weak Wi-Fi, downtime and unnecessary replacement costs.

Ask for advice before buying if the equipment is for business-critical work, multiple staff, Microsoft 365, networking, Wi-Fi, backup, security, POS systems or servers. Professional advice can help avoid compatibility issues and wasted spending.
