| math. | Bartlett's test of second order interaction | 바틀렛의 이차교호작용 검정 |
| comp., MS | bits per second | 비트/초 (The number of bits transmitted every second, used as a measure of the speed at which a device, such as a modem, can transfer data) |
| comp., MS | characters per second | 초당 문자 수 (A measure of the rate at which a device, such as a disk drive, can transfer data. In serial communications, the speed of a modem in bits per second can generally be divided by 10 for a rough determination of the number of characters per second transmitted) |
| math. | error of second kind | 베타오류, 제2종 오류 |
| comp., MS | frames per second | 초당 프레임 (The number of video frames displayed per second. Higher frame rates generally produce smoother movement in the picture) |
| comp., MS | kilobits per second | 초당 킬로비트 (Data transfer speed, as through a modem or on a network, measured in multiples of 1,024 bits per second) |
| comp., MS | kilobytes per second | 초당 킬로바이트 (Data transfer speed, as on a network, measured in multiples of 1,024 bytes per second) |

| math. | second kind model | 임의효과확률효과모형 |
| math. | second law of Laplace | 가우스분포 |
| math. | second law of Laplace | 정규분포 |
| math. | second law of Laplace | 라플라스-가우스분포 |
| comp., MS | second-level domain | 두 번째 수준 도메인 (A domain name that is rooted hierarchically at the second tier of the domain namespace directly beneath the top-level domain name such as .com and .org. When DNS is used on the Internet, second-level domains are names such as microsoft.com that are registered and delegated to individual organizations and businesses according to their top-level classification. The organization then assumes further responsibility for parenting management and growth of its name into additional subdomains) |
