ECESATUSB1 This Expresscard Power Esata Port Controller Card
1 Port ExpressCard Power eSATA Controller Adapter Card StarTech ID: ECESATUSB1 This ExpressCard Power eSATA port controller card can be installed in an available ExpressCard 34/54 mm slot to provide a powered eSATA connection, and also alternatively provide either external SATA (data only) or USB 2.0 connectivity from one uniquely designed port if using with standard eSATA or USB devices. An ideal solution for using an eSATA SSD Flash drive on your laptop, the power eSATA card delivers both a high speed eSATA connection and power from the combined USB port. A versatile connectivity solution, the card features built-in port multiplier support, allowing multi-drive eSATA storage enclosures to be connected to the host computer using a single eSATA cable. Taking advantage of the transfer speed of eSATA connection and the 5V power output of the USB 2.0 port, the ExpressCard Power eSATA adapter is the perfect answer for connecting compatible mobile drive enclosures, similar to the built-in power eSATA port provided by the following laptop computers: Toshiba: Satellite E105, A350, Satellite Pro P300; Qosmio G50, X305, Portege A600, M750, R500, R600; and Tecra M10, R10, A10. Dell: Studio 15, 17; Latitude E6400, E6500; Precision M2400, M4400, M6400, M6400 Covet. Applications Connects to eSATA SSD Flash drives, such as OCZ Throttle, Kangaru e-Flash drives and Ridata Racer series flash drives Provides connectivity between Notebooks and PCs with ExpressCard slots to external drive enclosures with Power eSATA (eSATA+USB) port, or with regular eSATA -
Computer Bus Characteristics
Upendra Sharma (upsharma.in) Computer Bus A bus, in computing, is a set of physical connections (cables, printed circuits, etc.) which can be shared by multiple hardware components in order to communicate with one another. The purpose of buses is to reduce the number of "pathways" needed for communication between the components, by carrying out all communications over a single data channel. This is why the metaphor of a "data highway" is sometimes used. If only two hardware components communicate over the line, it is called a hardware port (such as a serial port or parallel port). Characteristics A bus is characterised by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel. The term "width" is used to refer to the number of bits that a bus can transmit at once. Additionally, the bus speed is also defined by its frequency (expressed in Hertz), the number of data packets sent or received per second. Each time that data is sent or received is called a cycle. This way, it is possible to find the maximum transfer speed of the bus, the amount of data which it can transport per unit of time, by multiplying its width by its frequency. A bus with a width of 16 bits and a frequency of 133 MHz, therefore, has a transfer speed equal to: Upendra Sharma (upsharma.in) Types of Buses In reality, each bus is generally constituted of 50 to 100 distinct physical lines, divided into three subassemblies: The address bus (sometimes called the memory bus) transports memory addresses which the processor wants to access in order to read or write data. -
In This Video We Are Going to See How a Personal Computer Hardware Is Organised the PC Was Designed with an Open Architecture
In this video we are going to see how a personal computer hardware is organised The PC was designed with an open architecture. This means that it uses standard modular components. We can add, replace, update or swap them easily and the computer will identify and handle the new devices automatically. The main component of a computer system is the motherboard or main board. It is a printed circuit board (PCB) that holds the main components of the computer and the electronics needed to communicate between them and to expand the system. We could say that it is the central nervous system of the computer. A motherboard provides the electrical connections by which the other components of the system communicate. Unlike a backplane, it also contains the central processing unit and hosts other subsystems and devices The form factor is the specification of a motherboard – the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc. In the IBM PC compatible industry, standard form factors ensure that parts are interchangeable across competing vendors and generations of technology, while in enterprise computing, form factors ensure that server modules fit into existing rack mount systems. Traditionally, the most significant specification is for that of the motherboard, which generally dictates the overall size of the case. The most used form factor for IBM PC compatible motherboards is ATX (Advanced Technology Extended) and its derivatives. For small form factor mainboards mini ITX is the de facto standard. A power supply unit (PSU) converts mains AC to low- voltage regulated DC power for the internal components of a computer. -

Test-Drive Form That Follows Will Give You a Written Record to Reference at Your Own Pace in Your Own Home
56 Would You Buy a Car Without Test-Driving It? realize it isn’t such a big deal, and then continue learning more about the computer before you make your investment. It’s empowering to know that this is nothing more than a research expedition. No obligation, no financial outlay, no decision making. If you don’t want to go back, there is always the option of mail order or purchasing from the store by phone so you never have to reenter the place. And remember, if the salesperson you are dealing with really doesn’t appeal to you, give him the brushoff, let him get out of sight, smile sweetly at another salesperson, and watch her come running. Initially the computer store can sometimes add to any confusion you might have, especially after you get home and try to remember all you saw. The Test-Drive Form that follows will give you a written record to reference at your own pace in your own home. Copy these pages to bring with you to the store. If it’s easier, rip the pages out to make the copies. Test-Drive form 1. Store: Salesperson: Note the address and phone number of the store and the name of the salesperson you spoke with. 2. Brand & Model of Computer: Include any numbers that follow the brand name—this will indicate the model. For example: Dell Dimension 966. 3. Cost: Note the basic cost and any additional costs. For example: $499 plus $50 for RAM upgrade = $549. sYsTeM iNforMaTioN 4. Computer Case: h Standard h Tower Is the computer case a standard model or a tower model that will go on the floor?
