Q207.Which of the following device is used to connect similar LAN with same protocols?
Correct Answer: C
A network Bridge is used to connect two similar local area networks (LANs) that utilize identical network protocols to filter and segment traffic.
Q208.Which of following item is not usually in Local Area Network (LAN)?
Correct Answer: B
Standard local area networks (LANs) connect computers directly using cables and network interface cards (NICs); a modem (used for wide-area connection to ISPs) is not a basic requirement of a local network loop.
Q209.C language was developed by Dennis M. Ritchie in _____?
Correct Answer: A
Dennis Ritchie invented the C programming language in 1972 at AT&T Bell Laboratories to assist in rewriting the UNIX operating system.
Q210.Assembly language is one step higher than _____?
Correct Answer: C
Assembly language is a low-level programming language that is exactly one conceptual step above raw binary machine language.
Q211.Switch operates at _____ of OSI model.
Correct Answer: B

Q214.A compiled C language program file typically has which extension?
Correct Answer: A
C compilers generate machine-language object files, typically saved with a .obj (or .o) extension, before linking.
Q215.If you want to receive data transmission speed of 100 Mbps in a building, then which of the following transmission medium you will use ______?
Correct Answer: A
Unshielded Twisted Pair (UTP) Category 5/5e ethernet cabling is standard for high-speed local data transfers up to 100 Mbps within buildings.
Q216.If you want to display one of the cheapest and most affective network architecture in a building then which of the following network architecture you will apply?
Correct Answer: C
Peer-to-peer (P2P) network architectures do not require an expensive dedicated central server, making them cheap and effective for small offices.
Q217.Consider a laser printer task on a network. This printer cannot be taken away from one process to another process in the middle of printing job. This scenario is called _____?
Correct Answer: B
A non-preemptive resource is one that cannot be forcibly taken away from its current process until it is voluntarily released.
Q218.If you want to perform mathematical calculations whose value is an integer and is greater than 66.000 then which of the following data type you will use for storing numbers?
Correct Answer: C
Because standard short integers cannot exceed 32,767 in 16-bit encoding, you must use standard/long integers (None of these).
Q219.If you you use Star Topology in your office, then which of the following is the main advantage of using this topology?
Correct Answer: A
The primary advantage of a Star network topology is fault isolation; because each device is wired to the central hub independently, a single computer crash doesn't disable other computers.
Q220.If you have to connect various computers of a University then, which of the following network topologies will you use?
Correct Answer: A
Local Area Network (LAN) technologies are used to interconnect computers within localized bounds such as university campuses, buildings, or schools.
