SATA: SATA, Standing for Serial Advanced Technology Attachment, is a type of cable in which the hard-drive connects to the motherboard. The SATA cable makes use of point-to-point architecture in which the hard-drive can communicate with the motherboard. IDE: Standing for integrated device electronics, the IDE cable acts as an interface between the bus data paths which can be found on the motherboard and the hard-drive. EIDE: EIDE, standing for Enhanced Integrated Device electronics, is an enhanced version of the IDE, in which there are faster data transfers. The EIDE can be as up to 2x faster than IDE. Master/slave: USB: The USB port can be found on all computers. It is the interface in which a USB device or USB cable can connect to …show more content…
Serial data connection occurs one bit at a time. Devices such as modems use serial ports in order to exchange data. RAM: RAM, meaning random access memory, is a type of storage which can be found on computers. The RAM is used to store the data of the programs which are currently open. For example, if you had a set of values in a program which is currently open, then those values would be stored in RAM storage. The RAM communicates with other components through the memory bus. The RAM memory is also volatile, which means that it loses its data once the PC has been turned off. ROM: ROM, standing for read only memory, is a type of storage which can be found in the computer. The function of ROM is to act as a storage device for the instructions that the computer needs when it boots up. This means that the ROM is used every time the computer boots up. The ROM is also non-volatile, meaning that the ROM retains its data when the computer has turned off. The ROM chip can be found on the motherboard. The ROM communicates with other components through two data pathways; the address bus and the data …show more content…
Its function is to provide data to the CPU at a much faster rate, compared to RAM or from the Hard drive. If the cache size is bigger, then the performance is better as more data can be stored which is quickly accessible to the CPU. The cache stores things such as instructions that the CPU needs quickly. It is much quicker than RAM as it is found closer to the CPU. The Cache communicates with other components, such as the CPU throughout a data pathway, called the “backside-bus”. This pathway allows for very fast data transmission. The function of the network card is to enable to allow the computer to connect to a network, such as a home network. The network interface contains the circuitry required to connect to a network either wirelessly or wired. The network interface card communicates with other components using an Ethernet cable or wirelessly. A video card, or graphics card, possesses processing power in order to render high quality 3d graphics, and outputs images to be displayed. The graphics card has its own processor, which can process or render graphics quickly and efficiently. The graphics card outputs images to be displayed by monitors through various connections, such as HDMI. The graphics card receives data from various components in the computer through data routes, known as
This memory is assists in allowing the computer to simultaneously read and write data at the same time. Simply put, RAM is the most common form of memory that is utilized by computers as well as other devices. There are specific types of RAM that include dynamic random access memory and static random access memory, or DRAM and SRAM respectively. These two RAM are very different in terms of how they allow data to be read and written. Dynamic random access memory is often considered the most frequent type found in computers. Static random access memory is also found in computer, and is usually referred to as the faster of the two types due to the fact that refreshing of this form of memory is not needed whereas with dynamic random access memory it is. The term RAM is often used to describe what the computer uses to function. It is the main memory or primary memory whereby all processes and software run. Since it is random access memory, it is only available at the time a certain process is needed and is not stored anywhere on the computer specifically (2007). This is what makes random access memory often confusing to understand particular since computers also have what is known as read only
Inside the CPU are registers, arithmetic and logic units (ALU), a floating-point unit (FPU), control circuitry and cache memory. Registers are circuits designed to hold data so that it can be processed in some way by an ALU or the FPU. Cache memory is extremely fast, but small relative to the main memory. Cache memory is used to store the current set of working data and code. So when the processor needs to read the next bit of data or code, usually it can retrieve it much faster from the cache. On occasions when it must recall data from the (slower) main memory, the CPU is forced to wait instead of getting on with other operations.
BIOS stands for Basic Input Output System and is a small chip located on all motherboards. BIOS contains the information to It manages the data between the computer's operating system and attached devices such as the hard disk, keyboard , mouse , and printer .
A port is a point at which you can attach leads from devices to the
Inside of a standard desktop hard drive you will find one to four of the magnetic disks or as some call them platters. These platters are each 3.5 inches in diameter, different sizes are used depending on the device, such as the laptop version which is 2.5 inches, and in mobile devices some platter can be as little as 1 inch. The platters are coated in a magnetically sensitive material and stacked millimeters apart on a spindle. Also inside the drive is a motor that spins the spindle and platters at speeds of: 4,200, 5,400, 7,200, 10,000, and 15,000 RPM (Revolutions per Minute). The speed at which the platters spin is the primary factor in how fast the data can be read. Data is read or written on the disk in a series of bits, either a “0” or “1”. The bits are represented by the orientation of particles in the magneticall...
Ans: RAM is abreviated as Random Access Memory, is the main memory of computer in which the running programe is stored temporarily , it losts its memory when computer is turned off. While Cache memory is a special memory used to decrease the average time taken by RAM to access the programe. Cache memory is smaller memory as compared to RAM but it is much faster then RAM.
Random Access Memory (RAM) is where things currently in use are stored (7). RAM is volatile, things are only stored there temporarily and only when the power is on. If the power was turned off everything stored in the RAM would be lost unless saved to the hard
As the speed of the processors increase, it becomes difficult for the RAM to handle it. Dynamic RAM is used to reduce size and cost, which is a lot faster, but on the other hand expensive. “The temporary storage of` files on the microprocessor, is known as cache memory.” It may also be referred to as high speed memory and is controlled by a cache` controller that identifies which data & command would be required for the subsequent process & accordingly `loads it into the cache.
Encoding is the process of placing information into memory. Storage is the process of retaining information in memory. Getting information out of memory is called retrieval. Out of the three, the most important is Encoding, because you must pay attention to the information that you want to place into your memory. It is the starting point, although there are three levels known within this beginning step.
When using computer terms, it is very confusing trying to refer to different parts. Computers are basically broken down into two groups so help organize parts. Hardware is the term used to refer to items that you can physically touch and move with your hands (Dais interview). Software is the term used when referring to items you cannot touch like programs and applications.
Examples of internal system components include the central processing unit (CPU), the central chip that executes commands given to it. This central processing unit is often referred to as the “brain” of the computer because of its function. Random access memory (RAM), often simply referred to as memory, is a short-term storage device that holds instructions that are awaiting execution by the central processing unit. The amount of RAM installed in computer systems has increased over the years; common sizes today are 4, 8, and 16 gigabytes. Computer systems also have long-term storage, such as hard disk drives (HDDs), solid-state drives (SSDs), and external storage devices like USB flash drives, Secure Digital (SD) cards, and optical drives for media like DVDs and CDs.
According to the dictionary, Memory is defined as a device that is used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. Computers represent information in binary code, written as sequences of 0s and 1s. Each binary digit (or "bit") may be stored by any physical system that can be in either of two stable states, to represent 0 and 1. Such a system is called bistable. This could be an on-off switch, an electrical capacitor that can store or lose a charge, a magnet with its polarity up or down, or a surface that can have a pit or not. Today capacitors and transistors, functioning as tiny electrical switches, are used for temporary storage, and either disks or tape with a magnetic coating, or plastic discs with patterns of pits are used for long-term storage.(Dictionary.com 20014)
The motherboard is the most important part of your computer. It is also one of the most compared, critiqued, and reviewed pieces of hardware. Often, on the internet, you'll find reviews and debates over which board is best or which chipset is best. The chipset controls the system and its capabilities. It is the hub of all data transfer. It is a series of chips on the motherboard, easily identified as the largest chips on the board with the exception of the CPU. Chip s...
A motherboard is a much larger topic to discuss. The motherboard sometimes referred to as the mainboard, system board, planar board or logic board is the main printed circuit board in computers. It is a large board generally made of silicon that holds basically all of the crucial electronic components of the system. Components such as the CPU, memory, optical drives, video card, sound card and connections for other peripherals are fixed on the motherboard. Motherboards vary greatly as far as what components they are compatible with. Each mother board only supports one type of (CPU).
There are four types of memory. These are the RAM, ROM, EEPROM and the Bootstrap loader. The RAM, also known as Random Access Memory, is the temporary space where the processor places the data while it is being used. This allows the computer to find the information that is being requested quickly without having to search the hard drive space. Once the information has been processed, and stored onto a permanent storage device, it is cleared out of the RAM. The RAM also houses the operating system while in
