(religion, spiritualism, and occult)The Ram is a popular alternate name for the sign Aries.
What does it mean when you dream about a ram?
The ram is the symbol of the first sign of the zodiac, Aries. It is characterized by energy, aggression, and impulsiveness. In a dream, a ram may suggest that the dreamer rams headlong into situations that should be approached with more tact and consideration.

RAM
(Random Access Memory) The main memory in a computer, smartphone or tablet. RAM is the temporary workspace where instructions are executed and data are processed. What makes RAM "random access" is its capability of reading and writing any single byte. This "byte addressability" differs from storage devices such as hard drives and solid state drives (SSDs) that read and write many bytes (sectors or pages) at one time. In addition, RAM is used as a temporary space for the software, while storage is permanent until deleted by the user. To learn how RAM is used, look at the memory examples in computer. Also see memory, memory module and future memory chips.RAM Is Mostly DRAM
The most common type of RAM is dynamic RAM (DRAM). When a computer data sheet states 8GB of memory or 8GB RAM, it refers to DRAM (see dynamic RAM). Higher-speed SRAM is also used as an internal staging area (see static RAM).
Memory Is Often Not RAM!
A smartphone or tablet's specification of 16, 32, 64 or 128GB of memory does not refer to RAM; rather it is the unit's flash memory capacity for storing apps and data. The amount of internal RAM in a mobile device (typically 2GB to 6GB) is published on a tech specs Web page (see storage vs. memory).

| This magnetic drum was the memory in the IBM 650 computer in the mid-1950s. About 18 inches long, it held the equivalent of 20,000 bytes (20KB). That much RAM today would fit inside this letter "o" with plenty of room to spare. (Image courtesy of the Hagley Museum and Library.) |

| Core Memory - 1960s |

| In 1967, this 30-inch-high Dataram core memory module provided a whopping 16KB for a Data General minicomputer. Women in third-world countries were hired to string the cores together using a microscope. See core storage and early memory. |

| Compared to the Dataram example above, two thousand times as much RAM is available in two memory modules. |
Ram
the male of the sheep; the sire. The best rams for standardizing the breed are used as sires, and the remainder are castrated and bred for wool and meat.
Rams reach sexual maturity at four or five months, even earlier in early-maturing breeds. From that time on, the young males are separated from the young and mature ewes. Rams are put to stud from one-and-a-half to seven or eight years of age. The progeny of each sire numbers in the hundreds and with artificial insemination can number thousands; therefore, correct selection has great importance in the reproduction of the herd. The sire should be typical for the breed, of a strong constitution with no physical defects, healthy, energetic, and capable of transmitting these valuable qualities to the offspring. Lambs of the best parents are chosen to be raised as sires. They are culled at birth, at the age of three-and-a-half or four months, and again at one year of age. At the age of one-and-a-half, the ram is paired with 50 or 100 ewes and is evaluated according to the quality of the offspring.
The ram is put to stud three or four times a day. During the mating season (45 days), with artificial insemination, the sperm of one ram can usually fertilize 200 to 500 ewes, and on the most advanced farms, up to 3,000. Under penned conditions, one ram can service for 60 to 100 ewes; unpenned, one ram can service 20 to 30. The younger rams have a lighter stud load. The quality of the sperm is systematically tested. Rams must be kept under stud conditions. During the mating season, the feed for sires should be higher than average (but obesity must not be allowed). Rations should be rich in protein, vitamins, and minerals. The best feed for rams is leguminous hay, root plants, silage, oats, barley, and millet. Breeding rams are kept in a separate group. They must have five or six hours of exercise each day.
