(c) for transferring files from one machine to another

(d)  used to dynamically bind a high-level IP address to a low-level physical hardware address

(e) Used for transmission

Answer: Option b

Explanation:

Devices within a network use the Internet Control Message Protocol (ICMP) to communicate data transmission issues. In accordance with this description of ICMP, one of the main purposes of ICMP is to check whether data is reaching its target at the appropriate time.

Ques 3. Working with the WAN typically entails –

(a) ATM

(b) Satellite

(c) Frame delay

(d) All of these

(e) None of these

Answer: Option d

Explanation:

The WAN is often operated using satellites.
A wide area network (WAN) is a type of data network that connects computers over a large geographic area. Cities, states, and even entire countries can be connected through WANs. Additionally, WANs transmit data at slower rates than LANs do.
 

Ques 4. How many different characters can EBCDIC code?

(a) 8

(b) 16

(c) 64

(d) 256

(e) 512

Answer: Option d

Explanation:

Each letter or number in an EBCDIC file is represented by an 8-bit binary number (a string of eight 0s or 1s). There are 256 different characters that can be used, including alphabetic, numeric, and special characters.

Ques 5. Office LANs that are widely dispersed geographically can be linked utilising a corporate – 

(a) LAN

(b) WAN

(c) MAN

(d) DAN

(e) None of the above

Answer: Option b

Explanation:

For tiny geographic areas between 1 and 5 km in size, such as offices, schools, colleges, small companies, or a collection of buildings, local area networks are built. It is heavily utilized in both design and troubleshooting. Greater geographic coverage is provided by MAN than by LAN, including cities and districts. It might alternatively be thought of as an improved LAN network. MAN is made to connect a city or two villages through the network because LAN only covers a small portion of it.  WAN encompasses a wider range, from a state to a whole nation. As a result, it covers a region of between 100 to several thousand kilometers. Although WAN networks are complex, they are frequently utilized in mobile communications because they can span great distances.

Hence, the correct option is WAN.

Ques 6. There is a software that enables a personal computer to act like a terminal called:

(a) Terminal emulation

(b) Modem

(c) Super high frequency: 3000 MHz to 30000 MHz

(d) Ultra high frequency: 300 MHz to 3000 MHz

(e) None of these

Answer: Option d

Explanation:

Frequencies greater than 300 MHz are transmitted using space wave technology. Therefore, the 300MHz to 3000MHz frequency band is employed for TV transmission.

Ques 8. Which of the following methods is employed in time-to-line (TTL) programming?

(a) A method for best-effort delivery systems to prevent packets from looping indefinitely.

(b) A protocol trick where a lower level protocol takes a message from a higher level protocol and inserts it into the data section of the law level frame.

(c) When an IP gateway splits an IP datagram into smaller pieces for transmission across a network that cannot handle the original datagram size, one of the pieces is created.

(d) All of these

(e) None of these

Answer: Option a

Explanation:

Time-to-line programming is a method for best-effort delivery systems to prevent packets from looping indefinitely. A packet’s or data’s time-to-live (TTL) number indicates how long it should stay on a computer or network before being deleted. Depending on the situation, TTL, or packet lifetime, has many meanings.

Ques 9. Currently, the most popular input method is-

(a) Motherboard

(b) Scanner

(c) Keyboard

(d)  Mouse

Ques 10. Which of the following TCP/IP protocols has the lowest capacity and overhead for file transfers?

(a) TFTP

(b) TELNET

(c) FTP

(d) RARP

(e) None of these

Answer: Option a

Explanation:

A TCP/IP network, such as the Internet, uses the File Transfer Protocol (FTP) as a standard network protocol to exchange and manage files. The client and server applications of FTP have separate control and data connections and are designed on a client-server architecture.
 

Ques 11. Information can be transmitted through a half-duplex communication connection at:

(a) At timed intervals

(b) One direction only

(c) Both ways, but not at once

(d) Both ways at once

(e) None of the above

Answer: Option c

Explanation:

Each station can send and receive in half-duplex mode, but not simultaneously. Both devices can only receive when one is broadcasting and vice versa. When simultaneous communication in both directions is not required, the half-duplex mode is utilized.

(a) Only source address

(b) Only destination address

(c) Source and Destination address

(d) Source or Destination address

(e) None of the above

Answer: Option c

Explanation:

Both a header (20 or 24 bytes long) and contents are included in each IP packet (variable length). Along with other data that are used to route the packet, the header contains the source and destination IP addresses. The information is the content itself, like a list of words or a section of a website.
