Different Types Of Computers

RAM: RAM stands for Random Access Memory. It is a bit like a person's short-term memory. RAM is volatile so data only exists only when the computer is turned on, and is used by the operating system and other applications.

RAM (Random Accesses Memory): RAM is used by CPU when a computer is running to store the information that it needs to be used very quickly but it does not store any information permanently.

Your hard drives are what store all of your data, ranging from your operating system to your documents, music, and movies. If the RAM is your computer's short-term memory, your hard drive is the long-term memory. It stores the things you want to keep around for a while.

Level 3 or L3 cache is dedicated memory that works hand-in-hand with L1 and L2 cache to increase computer performance. L1, L2 and L3 cache are computer processing unit CPU caches, verses other kinds of caches in the system such as hard disk cache. CPU cache accommodates the needs of the microprocessor by anticipating data requirements so that processing instructions are delivered without interruption. CPU cache is quicker than random access memory (RAM), and is intended to stop bottlenecks in performance.

Random Access Memory (RAM) - the storage of data and instructions inside the primary storage is temporary. It disappears from the RAM as soon as the power to the computer is

Cache memory is the fastest memory outside of the CPU, runs at 10-30 ns per access.

a File or space on the hard drive where data from RAM is "swapped" in order to preserve space.

CPU : This is the central processing unit, better known as the processor. This is the heart of the PC where calculations are madeRAM: RAM stands for random access memory. This part in the PC grabs the file from the hard drive and stores on its non permanent memory so that you can have multiple windows open such as word and be able to access this data faster. The more RAM the faster and more apps you can open and the bigger the files the ram can hold. However, if you are using word and your pc crashes and you haven’t saved the file to the hard drive. The work that you have done will be lost due to that RAM does not hold on to files. GPU(Graphics card): The graphics

5. This chapter describes the concepts behind how a CPU reads the contents from RAM. Which of

The CPU is housed in the motherboard is considered the heart of the computer, it controls everything. CPU stands for central processing unit; it is one of the main components of a computer. The CPU or more commonly known as the processor is electronic circuitry which follows the instructions of the hardware and software on the computer, it effectively is a very efficient calculator carrying out arithmetic, logical, control and input/output operations.

CPU requirements: CPU is a stands for central processing unit .it is the main part of computer.CPU is the brain of the database

Important features to consider before purchasing a PC is the power (speed, RAM capacity), expandability, ports, ergonomics, compatibility (with hardware and software), footprint, support, warranty, and cost.

This information and instructions for the CPU are stored in Random Access Memory (RAM). This memory is the next hardware component for a bare bones PC referred to as the main memory. The CPU has direct access to any instructions for programs to be executed that are in the main memory and only in the main memory. The main memory is volatile which means it can only store data or instructions when the computer is powered on. The device that stores data when the PC is powered off is the hard drive. It is the computers primary method of storage. Another way it stores memory is through the floppy drive. This form of memory is removable.

Next we need to configure a reliable computer system for my friend that has a small, at home travel agency. With this system I would also recommend buying an already made system, and perhaps doing a few upgrades. Dell has the OptiPlex 3020 Micro which is a descent system for an at home business. It comes with an Intel Pentium G3240T Processor which is dual-core with HD Graphics. This dual-core processor has plenty of horsepower to work with for a small business, so there is really no need in upgrading this to a quad-core processor. It will allow you to answer e-mails while running Word, Excel, and PowerPoint, along with the Web browser. It also comes with 4 gigabytes of RAM, and there is

RAM is similar in behavior to a person’s short-term memory while Hard Disk is comparable to a person’s long-term memory. Short-term memory focuses on the task at hand , but it can only store enough information at a time, hence when it fills-up it will try to take information from the long-term memory bank. Computers also work in the same manner, If RAM fills up, the processor continually fetch and overlay existing data in RAM with new. Unlike Hard Disks, the RAM never runs out of memory.
