ICT in the Workplace and Computer Types

ICT in the Workplace

• ICT is important in almost every job imaginable
• Workers need to be able to source, process, and present data accurately and quickly
• Workers need to choose and use the correct ICT tools for the job

The Computer

• A computer's power depends on the CPU speed and performance, memory size, storage amount and type, and graphics card.
• A powerful PC can process more data, execute more tasks, and run more programs faster than a less powerful one.
• Computers process information in a cycle: take input, process it, produce output and store it.
• Computers communicate with other computers.

Types of Computers

• Laptops/Notebooks: Small, portable computers ideal for work and entertainment. They use miniaturized parts for lower power consumption.
• Tablets: Portable computers with touch or pen-sensitive screens made for quick, small-scale computing. They have special operating systems and long battery life.
• Smartphones: Perfect examples of digital convergence combining many device features on one device. A smartphone includes operating systems, large screens, and built-in data modems (3G, HSDPA, 4G/LTE).
• Desktops: Multi-purpose electronic devices.
• Servers: Computers that provide services or resources to other computers. They are more powerful than client computers.
• Dedicated Devices (e.g., ATMs, GPS): Designed for one specific task and aren’t considered computers

Protecting Your Information

• Hardware theft is about more than the replacement cost.
• Data stored on the computer may not have backups.
• Information may be sensitive or private.
• Portable devices are easily lost or stolen
• Companies sometimes disable USB ports to protect data.
• Social engineering tricks try to manipulate people.
• Ways to protect hardware from theft: record serial numbers, use ultraviolet markers, install hidden security software, use cable locks, and lockable cabinets.

Power Settings

• Computers should conserve power and 'sleep' or hibernate when not used.
• Setting up power plans helps manage computer power use.
• UPS (Uninterruptible Power Supplies) protect against power surges/spikes/outages.

The Role and Value of ICT in the Workplace

• Workers can work wherever they have access to a computer or the internet.
• Communication becomes easier and more effective.
• Vast amounts of data can be stored and processed for better decisions.
• ICT helps workers adapt to changing trends.
• ICT makes some jobs easier or safer (e.g., performing repetitive actions).
• ICT can empower smaller companies to compete globally.
• ICT also has some downsides

CAT (Computer Applications Technology) and Its Value

• CAT is a valuable subject, teaching students how to use computers to solve problems.
• Students learn to use computers for studying and research.
• Students get familiar with various software packages.

Additional Points

• Phablets: Devices that are between tablets and smartphones. They have larger screens than phones.
• Hybrid laptops/tablets: Laptops that can transform into tablet form.
• Memorandum/Memo on Teams: This refers to a written activity.
