Communication Systems & Word Processing

What is the difference between analog and digital data transmission methods?

• Analog data transmission is faster than digital data transmission.

• Analog data transmission uses digital signals.

• Analog data transmission uses continuous signals, while digital data transmission uses discrete signals represented by binary code.

• Digital data transmission uses continuous signals.

Explain the role of TCP/IP in network communication protocols.

• TCP/IP plays a crucial role in network communication by providing reliable data delivery and addressing/routing capabilities.

• TCP/IP is only used for wireless communication

• TCP/IP does not handle data delivery

• TCP/IP is primarily responsible for physical network connections

How does SMTP work in email systems?

• SMTP functions by encrypting emails with a secret code that only the recipient can decipher.

• SMTP works by sending physical mail instead of electronic messages.

• SMTP operates by using carrier pigeons to deliver emails.

• SMTP works by transferring email messages between servers using a set of commands and responses to ensure successful delivery.

What are the key features of file management in word processing software?

• Printing, spell-checking, formatting

• Sending emails, creating spreadsheets, editing videos

• Creating animations, inserting images, exporting to PDF

• Functions like saving, opening, renaming, deleting, and organizing files into folders.

Differentiate between WAN and LAN in terms of coverage and speed.

• WAN covers a small geographical area with slower speeds, while LAN covers a larger area with higher speeds.

• WAN covers a large geographical area with high speeds, while LAN covers a smaller area with slower speeds.

• WAN covers a large geographical area with slower speeds, while LAN covers a smaller area with higher speeds.

• WAN covers a small geographical area with high speeds, while LAN covers a larger area with slower speeds.

What is the purpose of modulation in data transmission?

• To decrease the speed of the data transmission

• To change the color of the data being transmitted

• To alter a carrier signal's characteristics to encode information for efficient transmission.

• To increase the weight of the data signal

List and explain the layers of the OSI model.

• Physical Layer, Data Link Layer, Network Layer, Transport Layer, Session Layer, Presentation Layer, Application Layer

• Data Layer, Network Layer, Transport Layer, Presentation Layer, Application Layer

• Physical Layer, Data Layer, Network Layer, Transport Layer, Presentation Layer, Application Layer

• Physical Layer, Data Link Layer, Network Layer, Transport Layer, Presentation Layer, Application Layer, Session Layer

How does POP3 differ from IMAP in email retrieval?

• IMAP downloads emails to the user's device and deletes them from the server, while POP3 syncs emails across devices and keeps them stored on the server.

• IMAP downloads emails to the user's device and deletes them from the server, while POP3 keeps emails stored on the server without syncing.

• POP3 and IMAP both delete emails from the server after downloading them to the user's device.

• POP3 downloads emails to the user's device and deletes them from the server, while IMAP syncs emails across devices and keeps them stored on the server.

What are the advantages of using cloud storage for file management?

• Higher risk of data loss

• Slower access speed

• Limited storage capacity

• The advantages of using cloud storage for file management include easy access from anywhere, automatic backups, reduced need for physical storage devices, scalability, and real-time collaboration.

Discuss the concept of packet switching in network communication.

• Packet switching involves sending data in a continuous stream without any division.

• Packet switching requires a dedicated point-to-point connection for data transmission.

• Packet switching does not involve any error-checking mechanisms during data transfer.

• Packet switching involves breaking data into packets, routing them independently, and reassembling them at the destination.
