Consider that a list of record or a table is stored in the memory and you wish to find some information in that particular list. E.g. the list comprises three fields as displayed below:
Assume that we want to find the age and ID number of Ravi. If we use conventional RAM, it is essential to give the exact physical address of entry associated to Ravi in the instruction access entry such as:
READ ROW 3
Another alternative idea is that we explore the whole list by means of the Name field as an address in instruction like:
READ NAME = RAVI
Again with serial access memory this option may be implemented simply but it's a very slow process. An associative memory assists at this point and concurrently examines all the entries in the list and returns the desired list very rapidly. SIMD array computers have been developed with associative memory. This memory is content addressable memory by which it's meant that multiple memory words are accessible concurrently. The parallel accessing feature support parallel search and parallel compare too. This ability can be used in numerous applications like:
The inherent parallelism characteristic of this memory has huge advantages and impact in parallel computer architecture. The associative memory is expensive compared to RAM. The array processor built with associative memory is termed as Associative array processor. In this section we explain a number of categories of associative array processor. Kinds of associative processors are based on organisation of associative memory. So first we discuss about associative memory organisation.
What are conversion routines? Non-standard conversions from present format to sap internal format and vice-versa are executed with so known as conversion routines.
How many responses does a computer expect to receive when it broadcast an ARP request? Why? An ARP (Address Resolution Protocol) request message is put in a hardware frame and
Floating point Arithmetic pipelines Floating point computations are the finest candidates for pipelining. Take the instance of addition of two floating point numbers. Following

Hashed strings can often be deciphered by 'brute forcing'. Bad news, eh? Yes, and particularly if your encrypted passwords/usernames are floating around in an unprotected file some
A shell is a program that presents an interface to several operating system functions and services. The shell is so called because it is an outer layer of interface among the user
Address 192.5.48.3 belongs to? Address 192.5.48.3 belongs to class C.
The aim of this project is for you to construct a fully working compiler for a small simple programming language, SPL. The compiler will read in SPL source code and produce ANSI C
What is the use of fork and exec system calls? Fork is a system call by which a new process is formed. Exec is also a system call, which is used after a fork by one of the two
