We know that memory is one of the most critical resources in our computer, but how does it really work? In this video, we’ll look at the fundamentals of memory operation and learn about memory transfer rates, throughput speeds, latency, read-only memory, and the differences between single-sided and double-sided memory.
It’s one of the worst sounds in the world; a hard drive mechanism that’s gone bad. It’s even worse when it’s the sound of YOUR hard drive that decided to up and die. Unfortunately, one of my hard drives recently decided to bite the dust, but I thought I’d use the untimely demise of my hardware to provide you with some insight on what you (or your clients) might expect to hear when a hard drive starts going south.
A CompTIA A+ professional is required to understand the details behind selecting, installing, and troubleshooting a personal computer CPU. In this module, we’ll discuss the decision making process for CPU selection, CPU installation techniques, and some tips and tricks for troubleshooting potential CPU problems.
The history of the modern CPU is a mix of technical prognostication, very smart people, and a drive to expand on our vision of the future. In this module, we’ll follow the path of CPU technology from the origin of the Pentium through the latest in processing technologies from Intel and AMD.
The configurations of CPUs onto a motherboard consist of a diverse set of slots, sockets, and connections. In this video, we’ll highlight some of these sockets types and show how a pin grid array processor fits into the zero insertion force sockets of today’s motherboards.
Modern technological advancements in CPU manufacturing have resulted in amazing increases in processing speed, but they’ve also introduced more complex computing architectures. In this module, we’ll discuss advanced features and technologies that have been integrated into today’s most popular CPUs.
The CPU is the heart and soul of the personal computer, but how does it really work? In this module, we’ll outline the basic structure of the central processing unit, and you’ll learn how the front side bus and system clock work together to enable the raw processing power of the CPU.
