RAM Random Access Memory
TASK 1. Read the article about RAM. Fill in the gaps with appropriate phrases (click the gap to get the list of options) RAM - Random Access MemoryRAM (pronounced ramm) 1. is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is found in servers, PCs, tablets, smartphones and other devices, such as printers.There are two main types of RAM:DRAM (Dynamic Random Access Memory)SRAM (Static Random Access Memory)DRAM (Dynamic Random Access Memory) – The term dynamic indicates that the memory 2. must be constantly refreshed or it will lose its contents. DRAM is typically used for the main memory in computing devices. If a PC or smartphone is advertised as having 4-GB RAM or 16-GB RAM, those numbers refer to the DRAM, or main memory, in the device.More specifically, most of the DRAM used in modern systems is synchronous DRAM, or SDRAM. Manufacturers also sometimes use the acronym DDR (or DDR2, DDR3, DDR4, etc.) to describe the type of SDRAM used by a PC or server. DDR stands for 3. double data rate , and it refers to how much data the memory can transfer in one clock cycle.In general, the more RAM a device has,4. the faster it will perform .SRAM (Static Random Access Memory) – While DRAM is typically used for main memory, today SRAM is more often used for system cache. SRAM is said to be static because 5. it doesn't need to be refreshed , unlike dynamic RAM, which needs to be refreshed thousands of times per second. As a result, SRAM is faster than DRAM. However, both types of RAM are volatile, meaning that they lose their contents when the power is turned off. TASK 2. Read about the difference between memory, RAM and Storage, put the verbs in brackets into the correct tense formand answer the questions in TASK 3.NB! Do not use short forms! The Difference Between Memory, RAM and StorageSometimes, people get confused (confuse) about the difference between memory and storage, in part because both can be measured (measure) in megabytes (MB), gigabytes (GB) and terabytes (TB).In common usage, the term RAM is synonymous with main memory. This is where a computing system stores data that it is actively using. Storage systems, such as hard drives, network storage devices or cloud storage, are where a system saves (save) data that it will need (need) to access later.Computing systems can retrieve data from RAM very quickly, but when a device powers (power) down, all the data that was (be) in memory goes (go) away. Many people have had (have) the experience of losing a document they have been working on after an unexpected power outage or system crash. In these cases, the data is (be) lost because it is (be) stored in system memory, which is volatile.By contrast, storage is slower, but it can retain data when the device is powered down. So, for example, if a document has been saved (save) to a hard drive prior to a power outage or system crash, the user will still be able (still to retrieve it when the system is back up and running.Storage is usually less expensive than RAM on a per-gigabyte basis. As a result, most PCs and smartphones have many times more gigabytes of storage than gigabytes of RAM.The Form Factors of RAMFor the most part, RAM comes (come) in two sizes: DIMM (Dual In-Line Memory Module), which is found (find) in desktops and servers, and SO-DIMM (Small Outline DIMM), which is found (find) in laptops and other small form factor computers.Though the two RAM form factors use (use) the same technology and functionally work in exactly the same way, you cannot mix them. You can’t just jam a DIMM stick into a SO-DIMM slot, and vice versa (the pins and slots do not line (line) up!).When you are buying RAM, the first thing to figure out is its form factor. Nothing else matters if the stick does not fit (not TASK 3. Read the article in TASK 2 and answer the questions. Q1: What are the memory measurement units?Q2: What is the reason for losing data in case of a power outage or system crash?Q3: What should be done in order to protect the data from being lost in case of unexpected system shutdown? (Your suggestion)Q4: What is the difference between DIMM and SO-DIMM RAMs? TASK 4. Find synonyms for the words and phrases in the table below. The synonyms can be found from both TASK 1 and TASK 2. costly producer bewildered to get something back sudden to squeeze likely to change previous to mean abbreviation TASK 5. How Does the RAM Work? Google for how the RAM operates and try to explain it in your own words (write at least three sentences).
