Computers, Software and Networked Systems

Hardware, software and networks are elements of a digital system. A computer may have a central processing unit, a hard disk, a keyboard, mouse, screen, and many other components. A peripheral device is a digital component that can be connected to a digital system.

Hardware Logic

Hardware logic is a different type of logic from other logic. Almost all computers have a power supply that is not involved in data processing but is used to power the data processing circuits. A computer may output information to a computer monitor audio amplifier which is not involved in the computational processes.

Analog and Digital Signals

A signal is an electrical current that is used to carry data from one system to another. The signal is a function that tells something. It refers to any time-varying voltage that is an electrical wave.

Software for Control of a Computer System

Hardware is only one part of a computer system, and there is also a controller embedded into it. Software that runs on top of the hardware makes use of the firmware to interface with the hardware.

Open Verification Library for Design Validation

The design validation process can be done through assertion verification where an assertion monitor is used to continuously check the validity of design specifications while the design is being simulation. The open verification library has assertion monitors. Hardware is generated from a design description.

Verilog and VHDL: A Hardware Description Language for FPGAs

Verilog and VHDL are the most popular hardware description languages. They are used in conjunction with the digital devices that are specifically designed to facilitate the creation of custom circuits. Hardware description languages allow you to describe a circuit using words and symbols, and then development software can convert that description into configuration data that is loaded into the FPGA in order to implement the desired function.

A Generalization of the Glyph

An image is a two-dimensional array of rows and columns. Digital image is made up of elements and elements. A digital image's elements are most often described by a glyph.

Understanding Computer Hardware Components

The same core components will be found in both laptops and desktop PCs, despite the design differences. Without hardware, computers wouldn't be able to run the essential software that makes them useful. The virtual programs that run on your computer are called software.

A power supply unit is more than just a power source for your computer. The point where power enters your system from an external source and is allocated to individual component hardware is called the "point of power". Without the right wattage PSU your system will fail to work, because not all power supplies are made equally.

Mobile Wallet: A Threat to Consumers

In May of 2011, the company launched a product called Google Wallet. The application could potentially be used to store information other cards, such as driver's licenses and health care cards, according to the vice president of commerce at the internet giant. Visa is researching or developing a digital wallet product.

Mobile wallet uses several technologies, including mobile apps, mobile hardware devices, near-field communication and security methods to create a secure and user friendly payment experience. Retailers are experimenting with using devices such as beacon to send relevant information to consumers. Mobile wallet is also being used with beacon.

They use low-energy, short-range, low-energy Bluetooth transmitters to send out notifications to mobile devices. Consumers may be told to redeem coupons, earn points or pick up items. When a consumer walks into a store, the store's beacon will communicate with the consumer's phone and highlight specials, discounts or coupons.

Concerns about customer data security are one reason for the gradual adoption of mobile wallet. Apple Pay and Google Wallet use tokenization, which masks credit card information and is transaction-specific to prevent hackers from gaining access to consumers' personal data. The random sequence acts as a substitute for the actual PAN while the data is in the retailer's systems.

Swords: a word for words in flash memory

straps are "swords" to indicate status with logic levels, such as read by the BIOS for configuration of RAM and may be hard-coded in flash memory.
