    About Cisco

    Approach to Quality
    Cisco's approach to quality can be condensed down to one phrase: "ensuring our customer success". The information contained in this section will help you to gain a better understanding of Cisco's Business Management System, which allows us to accomplish that success. Cisco's Business Management System is made up of two parts; the Quality Management System and the Environmental Management System.

    Cisco Fun Facts
    Cisco Systems, Inc. is an American multinational technology conglomerate headquartered in San Jose, California, in the center of Silicon Valley, that develops, manufactures and sells networking hardware, telecommunications equipment and other high-technology services and products. Through its numerous acquired subsidiaries, such as OpenDNS, WebEx, Jabber and Jasper, Cisco specializes into specific tech markets, such as Internet of Things (IoT), domain security and energy management.

    Cisco is the largest networking company in the world. The stock was added to the Dow Jones Industrial Average on June 8, 2009, and is also included in the S&P 500 Index, the Russell 1000 Index, NASDAQ-100 Index and the Russell 1000 Growth Stock Index.

    Cisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists, who pioneered the concept of a local area network (LAN) being used to connect geographically disparate computers over a multiprotocol router system. By the time the company went public in 1990, when it was listed on the NASDAQ, Cisco had a market capitalization of $224 million. Cisco was the most valuable company in the world by 2000, with a more than $500 billion market capitalization

    Title: Computer Memory/RAM: An Essential Guide

    Introduction:

    Computer memory, also known as RAM (Random Access Memory), is a crucial component in any computer system. With technological advancements and new software requiring more memory than ever before, having enough RAM is essential for your computer to operate smoothly and efficiently.

    In this guide, we'll cover everything you need to know about computer memory, including the different types of RAM, how it works, how much you need, and what to look for when purchasing memory modules to upgrade your desktop or laptop.

    Types of RAM:

    There are two main types of RAM in use today - DDR3 and DDR4. DDR3 has been the standard for many years but is being steadily phased out in favor of the newer DDR4 memory. Key differences include:

    • DDR4 has higher bandwidth, meaning it can transfer more data within a given time period.
    • DDR4 uses less power and generates less heat.
    • DDR4 modules have higher density - you can fit more memory capacity onto a single module.

    For most people looking to upgrade a computer in 2023, DDR4 is the best choice.

    How Does RAM Work?

    RAM stores data that the computer's processor needs to access quickly to function smoothly. Unlike storage drives, the data in RAM is temporary rather than permanent. The more RAM your system has, the more data can be loaded from storage into memory so the processor can work on it faster.

    Having insufficient RAM means the computer has to constantly swap data back and forth from the storage drive which significantly slows down performance. Upgrading your RAM allows more applications and background processes to stay running in memory at once.

    How Much RAM Do You Need?

    How much RAM you need depends on what you use your computer for. Basic web browsing and office work can get by on 4GB, but optimal performance for gaming or creative work like photo/video editing generally requires at least 8-16GB.

    For professional media creation or running multiple intensive applications at once, 32GB or more may be necessary. Check your existing RAM usage to determine if an upgrade is needed.

    What to Look for When Buying RAM:

    When purchasing RAM to upgrade your computer, there are a few key specifications to keep in mind:

    • Type - Make sure to get DDR4 SoDIMM RAM for laptops or DDR4 DIMM for desktops.
    • Speed - Faster RAM (measured in MHz) provides better performance, but make sure it is compatible with your system. For Intel processors, look for DDR4-2666 or higher.
    • Capacity - Determine how much RAM you need based on your usage and budget. 8GB or 16GB modules are common choices for most users.
    • Brand - Stick with major reputable brands like Corsair, Kingston, Crucial for reliability.

    Following these guidelines will ensure you get the right type of high-quality RAM to maximize your computer's performance. Investing in enough memory goes a long way!

    Upgrading your computer's RAM is one of the easiest and most cost-effective ways to significantly improve performance. Understanding the differences between DDR3 and DDR4 or DDR5 memory, checking your current usage, and purchasing a reputable high-speed module with sufficient capacity will allow you to multitask efficiently and get the most out of your system. Be sure to add enough RAM to meet your needs today and into the future.




    Random Access Memory, or RAM is the physical hardware inside a computer that temporarily stores data, serving as the computers working memory.
    Additional Memory / RAM allows a computer to work with more information at the same time, which will increase the performance of the entire system.

    Points to help make memory more understandable;
    What type of memory form factor are most common?
      There are two main types of memory, SODIMM (laptops) and DIMM (desktops)
    Speed and generation of memory.
      Remember your motherboard is only compatible with specific types, speeds and generations of memory.
      an example: DDR5 4800 MHz
    Memory size.
      With today's programs, games and web browsing, the more memory you have the better. In today's environment, the standard is around 8 GB, but more is always better!
      Please check your motherboard manual to confirm how much memory your board will handle.
    Storage using memory!
      There is a new type of storage called Solid State Drives or SSD's which is incredibly fast and reliable as there are no moving parts. SD Cards (SD/Flash) are memory based storage typically used for camera's, cell phones, and camcorders.

    The computer arrived yesterday! I am downloading files from my old computer for the moment, but wanted to thank you for the speedy delivery. I can't wait to set up the computer. I appreciate your communication and am impressed with the fast delivery. Thank you. Sincerely, Mary Mary
