Personal computer (PC)

A personal computer is a microcomputer designed for a single usertechtarget.com. Early PCs were largely confined to specialised workplaces, but by the 1980s advances in microprocessor technology meant that individuals could buy a small computer for word processing and other taskstechtarget.com. Modern PCs run an operating system and support a wide range of software, making them suitable for everything from spreadsheets and word processing to creative work, gaming and scientific researchtechtarget.com. They can be desktops, laptops, tablets or even smartphones, but the common thread is that they store and process data for the usertechtarget.com. Recent innovation has introduced AI PCs, which include a CPU, a GPU and a dedicated neural processing unit (NPU) so they can run machine learning models locallytechtarget.com. These systems integrate AI assistants such as Microsoft’s Copilot and include features like real time translation, intelligent video editing and enhanced battery efficiencytechtarget.com.

Example uses and learning activities

A general purpose PC is the workhorse of a classroom or office. Students might use it to draft essays, analyse data in a spreadsheet or design graphics for a presentation. Specialist software can transform a PC into a music studio or a programming environment. Many teachers now explore AI tools by running local language models on AI ready PCs, showing pupils how generative AI can summarise long texts or create images without sending sensitive data to cloud servers. An effective classroom activity involves pairing learners with tasks such as creating a short report, editing a photo and experimenting with an offline AI assistant to see how adding a neural processing unit changes performance and battery life. Discuss the results and encourage pupils to compare them with older PCs that lack AI hardware.

Server

A server is either a computer program or a physical machine that delivers services to client computerstechtarget.com. In a network the server hosts resources such as files, websites and applications and responds to requests from clientstechtarget.com. Servers can be dedicated machines housed in data centres or virtual machines running on cloud infrastructuretechtarget.com. They differ from desktop PCs because they are built for reliability: they often contain multiple CPU sockets, error correcting memory, redundant power supplies and network interfacestechtarget.com. Many organisations balance local servers with cloud servers; the former offer full control and can run mission critical applications on site, while the latter provide scalability without the need for physical racks and coolingtechtarget.com.

Example uses and learning activities

Servers sit at the heart of modern digital services. In education, a school may run its own file server to store coursework or a web server to host its intranet. A cloud server might deliver virtual learning environments accessible from home. To introduce students to server concepts, set up a small web server using a low cost computer such as a Raspberry Pi and have learners build a simple website. Ask them to compare the performance and control offered by hosting the site locally with the convenience of using a hosted service. More advanced students can experiment with virtual machines and learn how hypervisors partition hardware resources among multiple serverstechtarget.com.

Laptop

A laptop (also called a notebook) is a battery or AC powered personal computer that is smaller than a briefcase and easy to transporttechtarget.com. It can be used in temporary spaces, airports, classrooms, coffee shops, and can convert to a desktop by connecting to a docking station for monitors and peripheralstechtarget.com. Key characteristics include portability, screen resolution, processing power, memory and input portstechtarget.com. Modern laptops often include touch sensitive displays or convertible designs that fold into tabletstechtarget.com, and battery life remains a critical factortechtarget.com.

Example uses and learning activities

Laptops are indispensable to lecturers and students alike because they combine portability with the capabilities of a desktop computer. Pupils can take notes during lectures, collaborate on shared documents in the library and work on coding assignments while travelling. An engaging classroom exercise is to have students plan and execute a field project that relies solely on a laptop: for instance, designing a survey, collecting data in the community, then returning to class to analyse the results. Encourage them to consider battery life, the ergonomics of working without a full sized keyboard and the benefits of docking stations when they are back at their desks.

Tablet

A tablet is a wireless, portable personal computer with a touchscreen interfacetechtarget.com. Tablets sit between laptops and smartphones, offering a larger display than a phone but greater mobility than most laptopstechtarget.com. Users interact primarily via touch, though external keyboards and mice can be attachedtechtarget.com. Tablets generally have more storage and longer battery life than smartphonestechtarget.com and support Wi Fi and cellular networks for connectivitytechtarget.com. Many models automatically rotate the display thanks to built in accelerometerstechtarget.com.

Example uses and learning activities

Tablets are versatile educational tools. They work well for reading digital textbooks, annotating PDFs with a stylus and accessing video lectures. Creative subjects can leverage drawing and music apps, and language students can practise pronunciation with interactive exercises. A practical activity for younger learners involves using a tablet to document a science experiment: pupils can photograph each stage, record observations using a note taking app and assemble a digital lab report. Encourage them to adjust screen rotation to portrait for reading and landscape for video playback, and to experiment with connecting a keyboard when typing longer documents.

Smartphone

A smartphone is a cellular phone with an integrated computer that runs an operating system, provides web browsing and can run applicationstechtarget.com. These devices are used by consumers and professionals alike because they provide access to a wide range of apps and computing functionstechtarget.com. Typical uses include email, messaging, social media, health and wellness tracking, mobile payments and connecting to wearablestechtarget.com. Key features such as internet access, app stores, embedded memory, multitasking and a touchscreen make smartphones powerful tools for work and playtechtarget.com. Their portability and ubiquitous connectivity were especially valuable during remote learning periods and have been enhanced by 5G networkstechtarget.com.
