You will see three kinds of computers in offices: desktops, laptops and tablets. They all do similar work, but each suits a different situation. Knowing the difference helps you feel at home anywhere.

The three types

• Desktop — separate monitor, keyboard and mouse. It stays on one table. Strong and cheaper for the work it does.
• Laptop — everything joined into one folding unit. You can carry it to meetings or home.
• Tablet — a flat touch screen with no keyboard. You tap with your finger. Light and easy to carry.

When offices use each

• Desktop — for staff who sit at one desk all day, like accounts or data entry.
• Laptop — for people who move around, attend meetings, or work from home sometimes.
• Tablet — for quick tasks like showing a presentation, reading, or signing on screen.

Common ports (the slots you plug things into)

• USB — for pen drives, mouse, keyboard and charging cables.
• HDMI — to connect a bigger screen or a projector.
• Charger port — where you plug in the power cable to charge a laptop.
