UNIT III 8086 MICROPROCESSOR INTERFACING 3.1 Introduction This unit explains how to design and implement an 8086 based microcomputer system. To design an 8086 based system‚ it is necessary to know how to interface the 8086 microprocessor with memory and input and output devices. Due to the mismatch in the speed between the microprocessor and other devices‚ a set of latches and buffers are required to interface the microprocessor with other devices. In this unit‚ you will learn about the way in

ABSTRACT Communication generally and mass communication especially are concerned generally with who says what‚ to whom‚ in what channel and with what effect (Lasswell‚ 1948)‚ the sender/source‚ message‚ encoder‚ channel‚ decoder‚ receiver and feedback loop (Schramm‚ 1948). These two foundational mass communication theorists posit that communication is always intended to have an effect on the recipient and the society. Often it’s goal is to provoke change in the mind‚ environment

Presentation on Stuart Hall’s “Encoding/decoding” Hall‚ Stuart. “Encoding/decoding.” Culture‚ Media‚ Language. Ed. Stuart Hall et al. New York: Routledge‚ 1980. 128-138. Hall begins by pointing out that traditional research on communication has been critcised for being too linear by interpreting communication as a mere “circulation circuit” (128). He asserts that a better approach‚ conceptualised by Marx‚ is one which encompasses additional distinctive aspects of communication so that the

2008 differs from server 2003 with its new features like RODC‚ WDS‚32and 64bit‚and group policy editor. Some of the advantages of 64-bit architecture is more process address space‚ easily memory-mapped files over 4GB‚ and programs such as encoders‚ decoders‚ and encryption software benefit from 64-bit. Some of the new features of server 2008 are server core‚ PowerShell‚ and virtualization. Server core is a minimal installation option provides an environment for running the server roles. Some of the

NETWORK SECURITY WITH RFID SYSTEM AND CRYPTOGRAPHY ABSTRACT: Wireless communication is very common and widely applicable technique in communication field. In these field new techniques invented that is called RFID technique‚ in which object having RFID tags on them are being accessed in radio frequency region. Cryptography (method involves the both process “encryption” and “decryption”) is widely used in network system’s security. It is also the ancient method of encoding

RISC and CISC What is RISC RISC‚ or Reduced Instruction Set Computer. is a type of microprocessor architecture that utilizes a small‚ highlyoptimized set of instructions‚ rather than a more specialized set of instructions often found in other types of architectures. Every instruction in a single clock after fetch and decode. Smaller‚ less energy consumption. Sun Sparc‚ IBM Power series both have RISC RISC allows branch prediction and Pipelining because they require fixed length instructions
