Hyper-Threading (HT) technology

Intel’s Hyper-Threading (HT) technology enables a single CPU to accept and calculate two independent sets of instructions simultaneously, thereby simulating two CPUs. The technology was designed so that single CPUs can compete better with true multi-CPU systems but without the cost involved. In an HT environment, only one CPU is present, but the operating system …

CPU Speeds and Cores

Whereas Hyper-Threading (HT) technology simulates multiple CPUs, multicore CPUs physically contain two or more actual processor cores in one CPU package. These newer CPUs can have 2, 4, 6, or even 8 cores, each acting as a single entity but in some cases sharing the CPU cache . This enables more-efficient processing of data. Not …

CPU Cache

CPU cache is a special high-speed memory that reduces the time the CPU takes to access data. By using high-speed static RAM (SRAM) and because the cache is often located directly on the CPU , CPU cache can be faster than accessing information from dynamic RAM (DRAM) modules. However, it will be limited in storage …

32-Bit vs. 64-Bit Processing

Almost all of today’s PC-based CPUs are 64-bit; it’s a type of CPU architecture that incorporates registers that are 64 bits wide. These registers, or temporary storage areas, allow the CPU to work with and process 64-bit data types and provide support for address space in the terabytes. 64-bit CPUs have been available for PCs …

Troubleshooting a CPU

The most common issue with a CPU is when it isn’t installed properly or securely. This could possibly cause a complete failure when trying to turnon the system. This failure could be accompanied by a series of beeps from the POST. If this happens, always check the power first, just in case.Another possibility is that …

Installing a CPU

As with most computer components, installing a CPU is easy. But you must be careful because it can be easily damaged. Take it slow and employ proper safety measures. Let’s break it down into some simple steps: Select a CPU If you build a new computer, the CPU needs to be compatible with the motherboard …

What is a motherboard ?

One of the major replaceable components in computer is the system board, also known as the motherboard. The motherboard is the big green board connected to the computer case. It is the motherboard that holds RAM, processor, and a number of other components in place.

CPU Sockets

The CPU Sockets are the electrical interface between the CPU and the motherboard. It attaches directly to the motherboard and houses the CPU. It also physically supports the CPU and heat sink and enables easy replacement of the CPU. The socket is made of either plastic or metal and uses metal contacts for connectivity to …

What is a CPU?

The central processing unit, or CPU, is quite often referred to as the “brain” of the computer. A typical CPU today runs between 2 and 3.5 GHz or higher, uses multiple cores, and some can easily process 100 billion operations per second.

inside the PC

Most of the processing and storage devices show up “inside the PC.” the following are the major elements will find inside the system housing, or case : Processor/CPU The processor (also known as the central processing unit, or CPU) is the “brains of the organization,” so to speak. It is designed to do very few …
