1. What are the differences between Multitasking and Multiprocessing?
Multitasking- Enables the processor to do multiple programs simultaneously by fast switching through the programs. Here doesn’t have the involvement of multiple processors.
Multiprocessing- Enables the processor to do multiple programs simultaneously by the use of multiple processors.
2. What the difference between FSB and BSB?
Front Side Bus. Another name for the system bus. The Front Side Bus connects the CPU to main memory. A microprocessor bus that connects the CPU to a Level 2 cache is called Back Side Bus. Typically, a backside bus runs at a faster clock speed than the Front Side Bus.
3. What is packaging a microprocessor? What are the different packaging available?
Packaging is the process of connecting a microprocessor with a computers motherboard. The types of microprocessor packaging are;
a. PGA
b. SPGA
c. SECC
d. LGA
4. What is LGA ?
An LGA socket is the connection point for a central processing unit (CPU. to fit into a motherboard. The LGA stands for Land Grid Array.
5. What is CISC and RISC?
Reduced Instruction Set Computer (RISC. and Complex Instruction Set Computer (CISC. are two philosophies by which computer chips are designed. RISC became a popular technology buzzword in the 1990s, and many processors used in the enterprise business segment were RISC-based.
6. What is Intel Pentium?
The Intel Pentium is a series of microprocessors first developed by the Intel Corporation. These types of processors have been found in many personal computers since 1993.
7. Any difference between Pentium III and IV.
There have been a number of Pentium processor lines starting with the base Pentium in 1993.The of the recent Pentium entries are Pentium III and Pentium 4.
a. In a Pentium III processor, the bus speed is generally 133 MHz (although there were a few with 100 MHz). The lowest bus speed on a Pentium IV is 400 MHz, and there are versions with much higher speeds (topping at 1066 MHz for the “extreme edition”).
b. The Pentium 4s are smaller than the Pentium IIIs
c. Pentium III processors had (for the most part. about 512 KB of cache. Pentium 4 processors, on the other hand, start at 512 KB.
8. What are the differences between Intel Celeron and Pentium family of Processors?
Celeron
According to Build Gaming Computers, Celeron processors are the low-end processor intended for standard home computer use. SciNet reports the best Celeron processor has an L2 Cache of 128kb, a clock speed limit of about 2.0 GHz and runs at a core voltage of 1.75V. These are useful numbers for comparison.
Pentium
The top Pentium processor is the Pentium 4 Prescott. CPU Scorecard reports it has an L2 cache of 1MB (1024kb), a potential 3.0 GHz clock speed and runs at about 1.4V. The lowest performing Pentium 4 processor, the Willamette, has an L2 cache of 256kb, a potential 2.0 GHz clock speed and runs at about 1.7V.
9. What is Hyper Threading? What is the use of it?
A thread of execution, or simply a “thread,” is one series of instructions sent to the CPU. Hyper-threading is a technology developed to help make better use of spare processing cycles. Hyper-threaded processors have a duplicate set of registers, small spaces of high-speed memory storage used to hold the data that is currently needed to execute a thread. When a CPU core is delayed, waiting for data to be retrieved from another place in memory, it can use these duplicate registers to spend the spare computation cycles executing a different thread. The second set of registers will be pre-loaded with the data needed to execute the second thread, so the CPU core can begin work immediately
10. What is Intel Atom processor?
The Intel Atom family of processors are extremely small central processing units (CPU. found mostly in ultraportable devices, such as netbooks, cell phones and tablet PCs, according to Intel. While small and light on energy use, Atom processors can handle the most common tasks, such as email and instant messaging.
11. What is Nehalem Architecture?
Nehalem is Intel’s new microprocessor architecture The Core i7 chips were the first processors ever produced using an architecture called Nehalem.
12. Which is a heavy-duty Microprocessor of Intel?
Intel Xeon.
13. Which is the processor suitable from Intel family of processors for Server and Workstation?
Intel Xeon.
14. What is full name of AMD?
Advanced Micro Devices.
15. What are the latest Processor of Intel and AMD?
For intel it is Intel Core i7 and AMD Opteron 6200 Series processor.
16. Write socket LGA 775 is apt for which type of Intel Processors?
The top of the line for the LGA775 series CPU socket was the Core 2 processor series, with the Core 2 Duo E8600, Core 2 Extreme QX9770 and Core 2 Quad Q9650 being the three top performers
17. Socket 939 is developed by AMD. It supports a maximum of how many bits of computing? What are the the different processors of AMD is suitable for this socket?
AMD Athlon 64, AMD Athlon 64FX and AMD Athlon 64 X2.
30. Which type of socket is needed to connect a dual core processor of Intel?
Socket LGA 775.
18. What is Heat Sink? What is its use? If it is not in the system what will happen?
A heat sink is a component used to lower the temperature of a device.It is most commonly there on the microprocessor. If it is not properly fixed the system, the system will shutdown automatically to prevent further damage to the processor.
19. A CPU fan should be placed in system. Why?
To make the system cool and more functioning.
20. What is Upgrading a microprocessor? Why we have to do it?
Upgrading a microprocessor is just physically replacing a processor with a new one. Before doing so we have to make sure that the processor we want to use for your upgrade is physically compatible with the socket on your computer’s motherboard. We also have to make sure that the motherboard has the internal logic to support the processor.
