10+ Accenture Interview Questions and Answers

Flip-flops and latches are sequential logic circuits used to store and manipulate binary data.

• Flip-flops are edge-triggered devices, while latches are level-sensitive devices.

• Flip-flops have separate clock and data inputs, while latches have a single input for both clock and data.

• Flip-flops are used in synchronous circuits, while latches are used in asynchronous circuits.

• Flip-flops are more complex and require more circuitry compared to latches.

• Example of a flip-flop: D flip-...read more

BFS and DFS are two popular graph traversal algorithms. BFS explores the graph level by level while DFS explores the graph depth by depth.

• BFS uses a queue data structure while DFS uses a stack or recursion.

• BFS is guaranteed to find the shortest path between two nodes while DFS may not.

• BFS is better suited for finding the shortest path, while DFS is better suited for finding all possible paths or cycles.

• BFS has a higher memory requirement than DFS.

• Examples of BFS include findi...read more

Paging is a memory management technique used by OS to store and retrieve data from secondary storage.

• It divides the memory into fixed-size pages and stores data in these pages.

• It allows efficient use of memory by swapping out less frequently used pages to disk.

• It reduces fragmentation and improves memory utilization.

• Examples include Windows Virtual Memory and Linux Swap Space.

Flip flops are clocked storage elements that store data based on clock signal, while latches are level-sensitive storage elements that store data based on enable signal.

• Flip flops are edge-triggered, while latches are level-triggered.

• Flip flops have two stable states (0 and 1), while latches have only one stable state.

• Flip flops are used in synchronous circuits, while latches are used in asynchronous circuits.

TCP is a communication protocol that allows for reliable and ordered data transmission over a network. A network is a collection of interconnected devices that can communicate with each other. An IP address is a unique identifier assigned to each device on a network. A MAC address is a hardware address assigned to network interfaces for communication within a network.

• TCP stands for Transmission Control Protocol and is responsible for establishing and maintaining a connection ...read more

Computer networking involves connecting multiple devices to share resources and information. Different types of network topologies include bus, star, ring, mesh, and hybrid.

• Bus Topology: All devices are connected to a single cable, like a bus route.

• Star Topology: All devices are connected to a central hub, like a star.

• Ring Topology: Each device is connected to two other devices, forming a ring.

• Mesh Topology: Every device is connected to every other device.

• Hybrid Topology: Com...read more

C program to store employee id and name using array of strings

• Declare an array of strings to store employee id and name

• Use scanf to input employee id and name

• Print the stored employee id and name using printf

To reverse an array of strings, iterate through half of the array and swap elements from start and end.

• Iterate through half of the array

• Swap elements from start and end of the array

Address lines are used to specify a memory location, while data lines are used to transfer data to and from that location in a microprocessor.

• Address lines are used to select a specific memory location in RAM or ROM.

• Data lines are used to transfer data between the microprocessor and memory or I/O devices.

• For example, in an 8-bit microprocessor, there may be 16 address lines and 8 data lines.

• The number of address and data lines determines the maximum amount of memory that can ...read more

malloc and calloc are functions in C programming used for dynamic memory allocation, with the main difference being how they initialize memory.

• malloc() allocates uninitialized memory, while calloc() allocates zero-initialized memory

• malloc() takes a single argument for the number of bytes to allocate, while calloc() takes two arguments for the number of elements and size of each element

• Example: int *ptr = (int*)malloc(5 * sizeof(int)); vs int *ptr = (int*)calloc(5, sizeof(int)...read more

TCP is connection-oriented, reliable, and slower, while UDP is connectionless, unreliable, and faster.

• TCP is connection-oriented, meaning a connection must be established before data can be transmitted.

• TCP is reliable, as it ensures that all data is received in the correct order without errors.

• UDP is connectionless, meaning data can be sent without establishing a connection first.

• UDP is unreliable, as it does not guarantee delivery of data or ensure the order of delivery.

• TCP ...read more
