What are the advantages of risc and cisc?
Reduced Instruction Set Computing (RISC) is a CPU design concept that seeks gains in power as a trade-off for simplified instructions. This design philosophy is directly opposed to Complex Instruction Set Computing (CISC), which is the basis of the x86 style processors of the vast majority of home PCs and laptops.
Performance-OrientedThe construction of the RISC processor is such that performance is the priority, rather than raw power. When RISC and CISC were developed, the bottleneck of microprocessors was power, meaning that CISC won out and efficient, performance-oriented chips were used less and less. RISC came back into vogue when the need increased for chips that make efficient use of portable battery power.
Less VersatileSince the instruction set is so simple, that is, one instruction per cycle, RISC processors tend to be better used for simple and repetitive logic operations. CISC processors are truly "general purpose," meaning that they can pipeline multiple instructions at once without a preference for simpler or more complex applications. RISC processors need to be programmed in a very particular fashion.
SimplerThe performance orientation of the RISC architecture is due to its simple and efficient instruction set. This simplicity means that RISC processors are easier to design and inexpensive to produce, making them ideal for purpose-built and cheap computing machines that execute repetitive instructions.
Long Instruction StringsRISC processors can be adapted to run CISC style instruction strings, but they are incredibly inefficient at doing so. Since a RISC processor can only handle one instruction string at a time, code needs to be more compartmentalised and, therefore, more complicated.If it is an older laptop more than likely you won't be able to upgrade.
If it is a newer laptop, you can likely easily upgrade the processor.
To upgrade:
first dissassemble the laptop to the point you have access to the system board. A manual for dissassembly can often be fetched from the manufacturer's website. After you dissassemble the system to the system board, you will take off the heatsink or other cooling device, if applicable. A metal device covering a CPU, and often other components, and takes the head from it and to somewhere else. In a laptop, it often is a device covering the CPU, video card or other devices, and has a metal bar atop it going to where the fan is. To remove a heatsink or other cooling device from the top of a CPU, it is recommended you unscrew the screws holding it on in the 1-2-3 order indicated on top of the screws, if the numbers are present. Then, remove the processor. There will likely be a switch or lever, which can be easily moved to unsecure and resecure the CPU into the socket.
After the CPU is replaced, be sure to coat the top of it with a little thermal material, which helps transfer the heat from the CPU to the heatsink or other cooling device.
Note:
It is recommended you wear clothes which aren't too baggy, and have an anti-static mat to stand on while performing the operation, an anti-static bag to place components in while performing the operation, and perform the operation in a workplace with very little static electricity.
What is the temporary high-speed holding area between a secondary storagedevice and the CPU?
Disk Caching
Is clock speed measured in gigabytes?
Not really :-)
CPUs are measured in terms of instructions per second or calculations per second. At the lowest machine level, computer instructions will take 1 or more clock cycles to execute; because these machine instructions are variable, many people focus on the clock speed as an indication of processor performance.
That is why processors are often talked about in frequency terms (i.e. megahertz or gigahertz), but this is not strictly speaking a measurement of processor speed -- but it is closely related.
Megabytes and gigabytes are used to measure memory or disk size.
What retail system was made possible by microprocessors?
Just-in-time-delivery is made possible by microprocessors.
What are the chemical components of a microprocessor?
Some of the chemical components of a microprocessor is sand and silicon. The microprocessor is also made up of phosphorus and boron.
The other competitors were focused mainly on the lower-end market, where existing motherboards could be upgraded and existing stock could be used to make new, cheap products. Contrary to popular belief, it had nothing to do with patents, as AMD later used the same slot connector for Slot A, just rotated 180 degrees. There were also third-party chipsets for the Pentium II and later, so motherboards could easily have been created that supported both Intel processors and it's competitors.
Processor capacity refers to the maximum performance capability of a computer's CPU, often measured in terms of its clock speed (GHz), the number of cores, and the ability to handle multiple threads. It determines how efficiently the processor can execute tasks, process data, and run applications simultaneously. Higher processor capacity generally leads to improved performance, allowing for faster processing and better multitasking. However, the actual performance also depends on other factors like system architecture, memory, and software optimization.
How do you study microprocessor effectively?
with brain..writing on paper and just doing practice..this subject is to remember the commands so should be carefully start with basics so that can understand well when going through concepts .....and never try to remember just seeing it try to keep it on paper so that u can remember well..........
ALL THE BEST
What is the capacity of Intel CPUs?
CPU's or central processing units do not actually store data. There is a minimal amount of data on board but the storage takes place on the hard and solid state drives.
Method of processing that uses multiple processors simultaneously to execute a program?
Parallel Processing
Function of north bridge and south bridge?
North Bridge: CPU, Memory, GPU
South Bridge: I/O devices, keyboard, mice, NIC card
Excuse the previous answer as it was completely incorrect - CPU stands for Central Processing Unit.
The ADC 0804 A/D Converter is an 8bit A/D converter that uses successive approximation to convert the analog inputs to the digital output. The basic block diagram of the function of the successive approximation A/D Converter is shown in the figure above. The ADC0804 has four major sections namely the Comparator, the control logic, the digital counter and a 256R ladder D/A converter. For any analog input, the control logic will trigger the digital counter to start incrementing from zero count and these digital values are converted to analog form through a 256R ladder network. This 256R network consists of a number of resistors of fixed incremental resistance that produce a representative staircase type waveform based on the output of the digital counter. The output of the ladder network then enters the comparator which has the role of comparing the input analog to the analog output of the D/A Converter. When the staircase wave form exceeds the input voltage, the comparator sends a signal to the control logic to stop counting. The value of the digital counter at the time when the comparator sends the 'stop count' signal is the digital representation of the input voltage.
Is touch screen input or output?
Both. There's a touch panel that is used to feed information in to the device (input) and a screen underneath the touch panel to display stuff (output). This makes it to be both input and output.
How is the speed of a computer mesured?
The speed of a computer mouse is measured in dots per inch. If this number is high, the faster will be your mouse. Usually a computer mouse with 400 to 800 dpi will give you good experience.
Your answer is good ID3415191556
but I (SWARNIM)will like to add that, speed of mouse is measured in unit known asMICKEY.Less than 1mb. There is 1024kb in a meg. 736kb is far less than 1mb.
What came after the Intel Pentium 4?
The Intel Pentium D, Core Duos (and Solos), Core 2 Duos (and Quads), Pentium Dual-Cores, and the Core i7.
What is the difference between a CPU and a GPU?
The difference between a CPU and a GPU is that a CPU stands for central processing unit: (computer science) the part of a computer (a microprocessor chip) that does most of the data processing; "the CPU and the memory from the CPU and the memory form the central part of a computer to which the peripherals are attached". GPU stands for a graphics processing unit (also occasionally called visual processing unit or VPU) is a specialized processor that offloads #D graphics rendering from the microprocessor. It is used in embedded systems, mobile phones, personal computers, workstations, and game consoles.
An index register has the function of receiving, storing, and outputting instruction-changing codes in a computer. The index register is in a computer's CPU.
What is the clock in a microprocessor?
The clock is the amount of GHZ the processor can handle.
For example, the clock of a Core2Duo is of 2.4GHZ.
Overclocking means increasing the GHZ's the processor can handle but you will need a lot of cooling since the fan is not designed to handle such high GHZ's the people want.
How does the CPU interact with input devices?
On the most basic level, the keyboard is a collection of momentary switches. Each time you press a key down, you close one of these contacts. When you lift the key, the contact opens again. The electrical contacts are read and interpreted in the keyboard. Circuit logic within then determines which key was pressed or released. Finally, translation logic converts this information into a useable format which is then sent down the keyboard's wire (and/or wireless channel) and into the keyboard's connected bus. While in the old days keyboards had a dedicated low-bandwidth bus for this purpose, most keyboards these day employ the Universal Serial Bus, which defines how keyboards are supposed to operate. Either way, the computer receives the information from the keyboard through the bus which tells it what you just typed.
Maximum hard disk capacity a processor can address?
