Architecture Interview Questions

Latches do not have clock signal as input, while flip flops do.

LATCH: The latches are nothing but most basic types of flip-flops. the latches are level sensitive whereas flip-flops are edge sensitive. Thus the change of state in a latch will occur even for a...

in JK flip flop when both inputs are high (J & K) the output switches between 1 and 0 (toggle condition) continuously. this is known as race around condition.

after applying the clock the output must be changed only once, but it change continuously until the clock remains 1. this condition is called as race around condition. it can be eliminated by J-K master slave configuration.

Bus contention is when more than one device tries to drive data line at the same time. If one device is trying to drive it high and other tries to drive low then, we call it bus contention. Methods to...

we can avoid contention by using -
1 local memory
2 dual- port memory

Virtual Memory is same as Logical Memory, it is logical representation of memory reserved and can be controlled by programmer. Operating System introduces virtual memory concept which in-powers progra...

Design Patterns Design patterns are recognized solutions to common problems defined originally by the Gang of Four programmers. Design patterns are used throughout the ASP.NET Framework. The various ...

Because the files don't need to be compiled

You can use Windows Installer or latest versions of Install Shield.

MSI installers are Microsoft recommended for installations, and its advantages are silent/ network installations, automatic repair of deleted components/ files, and alleviated user rights during installations.

Embedding resource is the way using which we can deploy the image file or javascript file as the part of assembly. These files can then be easily accessed without having to worry about deployment issu...

The ability to make the file or image accessible from your server control’s assembly.
By this way, We can put related javascript/image all togather to avoid deployment problem

SOA is used so that a particular functional module can be treated as a separate service. Any other module can access that service. So a bigger application consituting many modules does not have to think about integration, it's all about accessing the service

Caching is the mechanism that allows frequently requested pages to be stored in the primary memory for faster retrieval. It helps to reduce network traffic.

Cache is used to store the values of the oftenly used values. It will store the value in cache memory and when ever we want that values we can get the required value from the cache if we stored the value in the cache.

The keyboard itself sends a binary signal to the keyboard driver of the OS, which then interprets the signal from  the keyboard as the OS sees fit - in Windows, these values are generally stored as 2-byte ANSI Unicode values based on the language code page in use.

Not exactly, the keys from the keyboard are not directly converted to ASCII values, keyboard generated a specific key code for every key pressed which is not the ASCII equivalent of that key. This key...

Through logic gates one can convert the ASCII value to corresponding binary value.
You can prepare a look up table (of say 4 inputs and 4 outputs), then make a K-map to reduce the binary expression relating the inputs and outputs. Than make the logic gate corresponding to the binary expression.

there must a kind of shift register that converts the hexadecimal representation character of ascii value to series of ones and zeros

Hello,

I found this interesting article on Pipelining...go through it...good info.

http://www.mozilla.org/projects/netlib/http/pipelining-faq.html

One of the Architectural goal of the interface is to create rules/contract for defining of what needs to be done in the component/implementation and most of the time you end up creating for specific l...

I believe this depends on the kind of interface and component you are designing.
If you indend to share your interface among different assemblies then it makes sense to place the interface in a client assembly.

DMA(direct memory acesses) it is used to transfer the data from the memory to i/o devices or vice versa without the intervention of processor.         &nbs...

I think this is about hardware architecture, so DMA stands for Direct Memory Access -- transferring the content of the memory to a I/O device (or back) without using the processor. 
Sending network packets, palying music etc

Some cases we may need to set this event to true. In those cases we need to handle the events within the postback check.

It will set a value to false or true which tells whether the ASP.NET pages are automatically connected to the event handling functions or not.By default it will be set to False.If it is set to true handlers will be executed twice.

Managed code it that which must be care by any intermediate manager. for eg. in dot net it is a interpreater based language. Allocation of memory is done by CLR. Garbage collection also plays a valuable role to manage the memory. and other featuers like security etc are also taking care by CLR.

Hai,

   Managed Code that is executed under the control of CLR  which uses .net BCL in it.FileStream Class is present in System.IO namespace so that it also falls under Managed Code.
