1. You must attach this tracing to your number 1 answer sheet
2. You must use pin to open four sides of this your drawing book to look as if you pinned it on a board before u started tracing.
3. You must use pin to open that A point and B point.
4. The red spots u are seeing is where u will open with pin.

(i) Videoconference:
Videoconferencing allows people in different locations to hold face-to-face meetings without having to move to a single location physically. It is widely used for business meetings, distance education, and medical consultations. Participants can see and hear each other in real-time through video and audio communication, share documents, and collaborate effectively.
(ii) Telepresence:
Telepresence refers to technologies that allow a person to feel as if they were present at a location other than their true location. It often involves sophisticated video conferencing equipment that provides high-definition video and audio, making it seem like participants are in the same room. Telepresence aims to create a more immersive and realistic interaction, enhancing remote communication.
(iii) Teleconference:
Teleconferencing is a telephone meeting among two or more participants involving technology more sophisticated than a simple two-way phone connection. It may involve audio, video, and data sharing. Teleconferencing is used for business meetings, training sessions, and seminars, enabling people to connect and collaborate without the need for physical travel.

(i) Registers are small, fast storage locations within the CPU that temporarily hold data and instructions. They facilitate quick data manipulation and processing by providing immediate access to operands and intermediate results during computation. Common types of registers include the accumulator, data register, address register, and status register.
(ii) The clock in a CPU is an electronic oscillator that generates a consistent signal used to synchronize the operations of the processor. This clock signal determines the speed at which the CPU executes instructions, measured in cycles per second or Hertz (Hz). A higher clock speed typically means a faster CPU, capable of performing more operations per second.
(iii) A bus is a communication system that transfers data between components of a computer. Within the CPU, the bus connects various parts, including the memory, input/output devices, and other peripherals. There are three main types of buses: the data bus (carries the data being processed), the address bus (carries the memory addresses where data is stored), and the control bus (carries control signals to coordinate the actions of the CPU and other components).

(ii) Cybercrime: The internet has facilitated various forms of cybercrime, including hacking, identity theft, online fraud, and cyberbullying. These activities can lead to financial losses, privacy breaches, and psychological harm.
(ii) Addiction: Excessive use of the internet, especially social media, gaming, and streaming services, can lead to internet addiction. This can negatively impact mental health, reduce productivity, and interfere with daily life and responsibilities.
(iii) Misinformation: The internet allows for the rapid spread of misinformation and fake news. This can lead to public confusion, panic, and the spread of false beliefs, impacting societal decision-making and trust in reliable information sources.
(iv) Privacy Concerns: The vast amount of personal data shared online can be misused, leading to privacy invasions. Companies and malicious actors can exploit this data for targeted advertising, surveillance, or malicious activities.
