L&T Emsys Interview Question Bank continued from Part 1… Q : Which is the basic gate used for TTL logic? A : The basic gate used for TTL logic is NAND gate. Q : What is pipelining? A : Pipelining is the process of en-queuing the next process to be executed while the current process is…
Let us now look at the questions asked in the recent times of interviews of L&T Emsys, a division of L&T Technology Services that deals with embedded systems and software development (and thus, the name L&T Emsys). It is an ECE core company which was incorporated in February 2001 and has three development centres in Mysore,…
Cisco Systems Interview Question Bank continued from Part 3… Q : What is the function of ALE in 8085? A : ALE stands for Address Latch Enable. In 8085 microprocessor, there are 16 address lines for 16 bit memory location. Of these 16 bits, higher order 8 bits are dedicated only for carrying the memory…

Cisco Systems Interview Question Bank continued from Part 2… Q : What is the sliding window concept in protocols? A : The sliding window is an abstract concept that defines the range of sequence numbers that are the concern of the sender and receiver. According to this concept, sender has its own concerned set of…

Cisco Systems Interview Question Bank continued from Part 1… Q : What is PAT? Give one real-life application of it. A : PAT (Port Address Translation) is an extension to NAT that allows multiple devices connected on a LAN to be mapped onto a single public IP address. PAT aims to conserve IP addresses. For example,…
