Study Notes
- Search engines use web crawlers to collect details of web pages and store them in a database called the Index.
- Search results are displayed in order of popularity, with sponsored links placed at the top based on how much a company pays.
- Users can enhance their search queries using operators like quotes for exact words, minus sign to exclude words, and OR for multiple keywords.
- Emails are stored on servers and forwarded to recipients, allowing for asynchronous communication between senders and receivers.
- Advantages of email include high/low priority settings, address book features, while disadvantages include junk email (spam) and potential security risks like phishing.
- Email protocols like SMTP, POP3, and IMAP allow for sending and receiving emails on different devices and software.
- Packet switching is the process of breaking internet data into packets for efficient transmission, with packet headers containing vital information for reassembly.
- Transmission modes include simplex (one-way), duplex (two-way), and half-duplex (take turns) for devices on a network to communicate.
- VoIP utilizes packet switching to encode and decode audio/video data in packets for efficient transmission over the internet.
- Wired transmission methods include serial (one bit at a time) and parallel (multiple bits at once) transmission for data transfer over different distances.
