One of the most important characteristics of a computer is its capability of storing information in its memory long enough to process it. 1__________________________________.
The memory of the first computers was made up of a kind of grid of fine vertical and horizontal wires. At each intersection where the wires crossed there was a small ferrite ring called a core and therefore we use the name “core memory”. 2__________________________________. There is one problem, however, with semiconductor memory: when power is removed, information in the memory is lost, unlike core memory which is capable of retaining information during a power failure.
3__________________________________. A magnetic bubble memory can store information at a greater density than existing memories, which makes it very suitable. 4__________________________________.

The Stage Model of Memory
1. Sensory memory is the earliest stage of memory. During this stage, sensory information from the environment is stored for a very brief period of time, generally for no longer than a half-second for visual information and 3 or 4 seconds for auditory information. We attend to only certain aspects of this sensory memory, allowing some of this information to pass into the next stage - short-term memory.
2. Short-term memory, also known as active memory, is the information we are currently aware of or thinking about. In Freudian psychology, this memory would be referred to as the conscious mind. Paying attention to sensory memories generates the information in short-term memory. Most of the information stored in active memory will be kept for approximately 20 to 30 seconds. The amount of information that can be stored in short-term memory can vary. An often cited figure is plus or minus seven items. While many of our short-term memories are quickly forgotten, attending to this information allows it to continue on the next stage - long-term memory.
3. Long-term memory refers to the continuing storage of information. In Freudian psychology, long-term memory would be call the preconscious and unconscious. This information is largely outside of our awareness, but can be called into working memory to be used when needed. Some of this information is fairly easy to recall, while other memories are much more difficult to access. The ability to access and retrieve information from long-term memory allows us to actually use these memories to make decisions, interact with others and solve problems.

A computer system is a collection of components that work together to process data. The purpose of a computer system is to make it as easy as possible for you to use a computer to solve problems. 1___________________________________. The hardware elements are the mechanical devices in the system, the machinery and the electronics that perform physical functions. 2___________________________________. Documentation includes the manuals and listings that tell you how to use the hardware and software.
3__________________________________. Usually, a computer system requires three basic hardware items: the computer, which performs all data processing; a terminal device, used like a typewriter for two-way communication between the user and the system; and a storage medium for storing programs and data. 4__________________________________.

Peripheral devices are categorized as input/output (I/O) devices since the functions they perform provide information (input) to the computer, accept information (output) from the computer, or do both. 1__________________________________. Terminals and storage devices are input/output devices because they perform both input and output operations.
2_________________________________. These programs include operations, functions, and routines that make it easier for you to use the hardware to solve problems and produce results. 3___________________________________. Others perform difficult or lengthy mathematical calculations. 4_____________________________________.

A disk is a data storage medium consisting of a flat, circular, magnetic surface on which information can be recorded. 1_________________________________. These already contain information and programs, and are ready to use.
2______________________________. But these disks must be formatted before they can be used.
3______________________________. This means you can read from but not write to the disk, making it impossible to write accidentally over information. 4_______________________________.

Power dividers serve a multitude of circuit and system applications, from amplifiers to radar receivers. The power divider is housed in a hermetic enclosure with stainless-steel female SMA connectors. As these stripline power dividers feature such small physical dimensions, more than 20 power dividers can be fabricated from a single substrate. Unit-to-unit amplitude tracking is specified as better than ±0.6 dB, while standard unit-to-unit phase tracking is better than ±6 deg. at 18 GHz.
Insertion loss (in excess of expected power-division losses) is less than 2.0 dB.
The four-way power divider boasts amplitude balance of better than ±0.4 dB. Phase balance is better than ±5 deg. Designed to handle input power levels to 1 W CW, the power divider supports wide-dynamic-range signal processing.
