A computer is an electronic device that processes information based on input and instruction. The devices can be programmed to execute a wide range of tasks, from browsing the internet to word processing. The primary components of a computer are the central processing unit (CPU) and random-access memory (RAM), which work together to perform calculations and store data.
What are the different types of computers?
There are several types of computers, including desktops, laptops, tablets, and smartphones. Each of these devices is designed for a specific purpose and comes with its unique set of features.
What is operating system software?
The operating system is the software that powers your computer. It manages the hardware resources, software applications, and other system components allowing users to operate the device. Some popular operating systems include Windows, macOS, and Linux.
Section 2: Computer Security
What is computer security, and why is it important?
Computer security refers to the measures taken to protect your computer against unauthorized use, attacks, and viruses. With the increase in online activities ranging from e-commerce to social media, it’s essential to safeguard your device and data from malicious actors.
How can I protect my computer from malware?
One way to protect your computer from malware is to install antivirus software. Other preventative measures include keeping your operating system up to date, using strong passwords, avoiding suspicious email attachments, and exercising caution when browsing the internet.
