ABSTRACT:
Embedded system encompasses a variety of hardware and software components, which perform specific functions in host systems. Embedded systems have become increasingly digital with a non-digital periphery and therefore, both hardware and software co-design is relevant. Majority of computers are used in such systems to distinguish them from standard main frames, workstations and pcâ„¢s. Advances in microelectronics have made possible applications that would have been impossible without an embedded syst ....etc

Deadlock
A deadlock is a situation wherein two or more competing actions are waiting for the other to finish, and thus neither ever does.
Example : “When two trains approach each other at a crossing, both shall come to a full stop and neither shall start up again until the other has gone.”
Deadlock Examples
A deadlock refers to a specific condition when two or more processes are waiting for each other to release a resource, or more than two processes are waiting for resources in a circular chain.

Todayâ„¢s mobile professionals need to stay in regular contact with important sources of information such as the Internet, email, corporate networks and remote databases. As demand for Wide Area Networking (WAN) connectivity continues to grow, users and organizations are seeking ways to make it more efficient and productive. One of the most promising new technologies for this purpose is General Packet Radio Service (GPRS). GPRS is a packet-switching data network that is overlaid on the existing cellular voice network, using the same radio ....etc

ABSTRACT
lwIP is an implementation of the TCP/IP protocol stack.. Interest for connecting small devices to existing network infrastructure such as global internet is steadily increasing. Such devices often has very limited CPU and memory resources and may not able to run an instance of TCP/IP protocol suite.
The focus of the lwIP stack is to reduce memory usage and code size, making lwIP suitable for use in small clients with very limited resources such as embedded systems. In order to reduce processing and memory deman ....etc

Virtual memory
¢ Virtual memory is an illusion of a memory that is larger than the real memory
“ Only some parts of a process are loaded in memory, other parts are stored in a disk area called swap space and loaded only when needed
“ It is implemented using noncontiguous memory allocation
* The memory management unit (MMU) performs address translation.
“ The virtual memory handler (VM handler) is that part of the kernel which manages virtual memory

ABSTRACT
Virtual storage access method (VSAM) is an IBM disk file storage
access method, first used in the OS/VS2 operating system, later used
throughout the Multiple Virtual Storage (MVS) architecture and now in
z/OS. Originally a record-oriented filesystem, VSAM comprises four
data set organizations: Key Sequenced Data Set (KSDS), Relative
Record Data Set (RRDS),Entry Sequenced Data Set (ESDS) and Linear
Data Set (LDS). The KSDS, RRDS and ESDS organizations contain
records, while the LDS organization ( ....etc

INTEGRATED GUIDED MISSILE DEFENCE PROGRAMME (IGMDP)
ABSTRACT
IGMDP “ INTEGRATED GUIDED MISSILE DEFENSE PROGRAMME

The Integrated Guided Missile Defense System (IGMDP) is the most advanced technology in the field of ballistic war faring. Perfectly pin pointing enemy missiles and striking them airborne forms the essence of this technology. Precision and accuracy are the most inevitable factors that have to be ensured here. This system makes use of several stages comprising of different equipments and the integra ....etc

Chapter 1. Introduction
By combining the C programming languageâ„¢s liberal approach to memory
handling with specific Linux filesystem permissions, this operating system
can be manipulated to grant unrestricted privilege to unprivileged accounts
or users. A variety of exploit that relies upon these two factors is commonly
known as a buffer overflow, or stack smashing vulnerability. Stack smashing
plays an important role in high profile computer security incidents. In order
to secure modern Linux systems, it is nec ....etc

1.0 Introduction
Telecom store is the first point to step in for a mobile connection. This store is an
inventory for all kinds of products. Store maintains different kinds of product
models in the inventory such as handsets, SIMs, accessories etc. The
management of this store is an extremely important aspect of making sure that
customers receive what they need and when they need it. It is very important to
maintain track of Telecom equipment in the store to prevent disaster.
Customers can walk in a retail store and place ord ....etc

In computer science dynamic memory allocation is the allocation of memory storage for use in a computer program during the runtime of that program. It is a way of distributing ownership of limited memory resources among many pieces of data and code. A dynamically allocated object remains allocated until it is deallocated explicitly, either by the programmer or by a garbage collector this is notably different from automatic and static memory allocation. It is said that such an object has dynamic lifetime.

The problem of fulfilling an allocati ....etc
