Magnetic Disk vs. Optical Disk vs. SSD: An In-Depth Comparison
On February 5, 2023 In Computer Architecture
In this blog post, we will explore the differences between magnetic disks, optical disks, and solid-state drives (SSD). We will compare them on important features such as access speed, storage density, and longevity to help you make an informed decision which one is the right choice for you. We’ll start with a brief introduction
Hard Disk vs Floppy Disk: A Comparison
On February 3, 2023 In Computer Architecture
Hard disks and floppy disks are two types of storage devices used in computers. Hard disks use magnetic media to store data, while floppy disks use laser technology to encode information onto an aluminum foil-coated diskette. While hard disks are still widely used, floppy disks are an outdated technology. In this post, we’ll compare
Raid 1 vs Raid 10: Exploring the Difference
On February 2, 2023 In Computer Architecture
RAID 1 and RAID 10 are both data storage techniques that use two or more hard drives to store information in a redundant fashion. There are distinct advantages and disadvantages to each approach. In this blog post, we will look at how these different types of Redundant Arrays of Independent Disks (RAID) work, compare
An Introduction to Memory Registers
On January 31, 2023 In Computer Architecture
Memory registers are fundamental components of memory used in computers and other digital devices. Each type of register has its own unique purpose in helping to create efficient operations within a computer system. In this blog post, we will explore each type of memory register as well as the advantages and disadvantages associated with
An Introduction to Semiconductor Main Memory
On January 24, 2023 In Computer Architecture
Semiconductor main memory is an integral part of the modern computing system. It enables us to store and retrieve data in a fast and efficient manner, providing quick access to information that would otherwise be unavailable or take too long to obtain. In this blog post, we will explore different types of semiconductor main
Understanding Locality of Reference and its Implications
On January 22, 2023 In Computer Architecture
Locality of reference describes a property of computer systems where the access patterns of a program or system tend to cluster around locations and over a short period of time. This behavior can be exploited by computer systems to optimize memory and cache usage, resulting in improved performance. Locality of reference can have significant impacts
Physical Cache vs. Virtual Cache vs. Virtual Memory: Understand How Caching Solutions Work and Where They Differ
On January 18, 2023 In Computer Architecture
Physical cache refers to memory that is physically located on a computer or device, such as CPU cache or disk cache. A virtual cache usually refers to a cache that uses virtual addresses instead of physical addresses for mapping into RAM. The difference is that a physical address needs to be translated into a
What is the Purpose of Cache Memory and How Does It Work?
On January 14, 2023 In Computer Architecture
Cache memory is an important component of modern computer systems, as it enables data to be accessed quickly and efficiently. This article will explain the purpose of cache memory, how it works, its benefits and types as well as when it should be used rather than main memory. With this knowledge in hand, you
How PCI-Express and PCI work: An Introduction
On January 13, 2023 In Computer Architecture
Peripheral Component Interconnect (PCI) was developed by Intel as a processor-independent bus. PCI is completely in the public domain and became established as a standard for high-speed connections of peripheral devices to the motherboard. Because of its versatility, it has increasingly been used in server systems in the 1990s. PCI Express (PCIe) is a
From the Computer Bus to Point-to-Point Interconnect: An Overview of Bus Interconnection Structures
On January 6, 2023 In Computer Architecture
A bus in computer architecture is a medium for transmitting information between devices. In a typical computer, you have a central processing unit, system memory, and some I/O devices that need to communicate with each other. Busses connect all of these components together as a shared transmission medium. This means a signal sent by
