Perangkat keras komputer adalah semua bagian fisik komputer, dandibedakan dengan data yang berada di dalamnya atau yang beroperasi didalamnya, dan dibedakan dengan perangkat lunak (software) yang menyediakaninstruksi untuk perangkat keras dalam menyelesaikan tugasnya. Hardware dalam bahasa Indonesia disebut juga dengan nama “perangkatkeras” yaitu salah satu komponen dari sebuah komputer yang sifat alatnya bisa dilihat dan diraba secara langsung atau yang berbentuk nyata, yang berfungsiuntuk mendukung proses komputerisasi. Hardware dapat bekerja berdasarkan perintah yang telah ditentukan atau disebut juga dengan istilah “instruction set”. Adanya perintah yang dapat dimengerti oleh hardware, maka hardware tersebutdapat melakukan berbagai kegiatan yang telah ditentukan oleh pemberi perintah.

Perangkat keras komputer adalah semua bagian fisik komputer, dan dibedakan dengan datayang berbeda di dalamnya atau yang beroperasi di dalamnya, dan dibedakan dengan perangkat lunak ( software) yang menyediakan instruksi untuk perangkat keras dalam menyelesaikan tugasnya. Hardware dalam bahasa Indonesia disebut juga dengan nama " Perangkat keras " Yaitu salah satu komponen dari sebuah komputer yang sifat alatnya bisa dilihat dan dapat di raba secara langsung atau yang berbentuk nyata, yang berfungsi untuk mendukung proses komputerisasi. Hardware dapat bekerja berdasarkan perintah yang telah ditentukan atau disebut juga dengan istilah " Instruction set". Adanya perintah yang dapat dimengerti oleh hardware,, maka hardware tersebut dapat melakukan berbagai kegiatan yang telah ditentukan oleh pemberi perintah. Secara fisik, komputer terdiri dari dari beberapa komponen yang merupakan suatu sistem. Sistem adalah komponen- komponen yang saling bekerja sama membentuk suatu kesatuan. Apabila salah satu komponen tidak berfungsi, akan mengakibatkan tidak berfungsi nya proses proses yang ada dalam komputer dengan baik. Komponen komputer ini termasuk dalam kategori elemen perangkat keras ( hardware). Berdasarkan fungsinya, perangkat keras komputer dibagi menjadi:input device ( unit masukan) ; proses device ( unit pemrosesan) ; output device ( unit keluaran) ; backing storage ( unit penyimpanan) ; dan Porifera( unit tambahan).

Background: Cloud storage is generally used to provide on-demand services with sufficient scalability in an efficient network environment, and various encryption algorithms are typically applied to protect the data in the cloud. However, it is non-trivial to obtain the original data after encryption and efficient methods are needed to access the original data. Methods: In this paper, we propose a new user-controlled and efficient encrypted data sharing model in cloud storage. It preprocesses user data to ensure the confidentiality and integrity based on triple encryption scheme of CP-ABE ciphertext access control mechanism and integrity verification. Moreover, it adopts secondary screening program to achieve efficient ciphertext retrieval by using distributed Lucene technology and fine-grained decision tree. In this way, when a trustworthy third party is introduced, the security and reliability of data sharing can be guaranteed. To provide data security and efficient retrieval, we also combine active user with active system. Results: Experimental results show that the proposed model can ensure data security in cloud storage services platform as well as enhance the operational performance of data sharing. Conclusion: The proposed security sharing mechanism works well in an actual cloud storage environment.

Background: With the growing demand of image processing and the use of Digital Signal Processors (DSP), the efficiency of the Multipliers and Accumulators has become a bottleneck to get through. We revised a few patents on an Application Specific Instruction Set Processor (ASIP), where the design considerations are proposed for application-specific computing in an efficient way to enhance the throughput. Objective: The study aims to develop and analyze a computationally efficient method to optimize the speed performance of MAC. Methods: The work presented here proposes the design of an Application Specific Instruction Set Processor, exploiting a Multiplier Accumulator integrated as the dedicated hardware. This MAC is optimized for high-speed performance and is the application-specific part of the processor; here it can be the DSP block of an image processor while a 16-bit Reduced Instruction Set Computer (RISC) processor core gives the flexibility to the design for any computing. The design was emulated on a Xilinx Field Programmable Gate Array (FPGA) and tested for various real-time computing. Results: The synthesis of the hardware logic on FPGA tools gave the operating frequencies of the legacy methods and the proposed method, the simulation of the logic verified the functionality. Conclusion: With the proposed method, a significant improvement of 16% increase in throughput has been observed for 256 steps iterations of multiplier and accumulators on an 8-bit sample data. Such an improvement can help in reducing the computation time in many digital signal processing applications where multiplication and addition are done iteratively.
