Ohio House Bill Number 110, passed in July 2021, included several new provisions for K-12 computer science education. The law requires the Ohio Department of Education to update the Ohio Learning Standards and Model Curriculum for Computer Science within one year of the effective date of HB 110 (Ohio Revised Code 3301.079(A)(4).
DRAM (dynamic random access memory) is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function. DRAM is a common type of random access memory (RAM) that is used in PCs, workstations and servers. Random access allows the PC processor to access any part of the memory directly ...
Ohio’s Standards in Computer Science are fully aligned to Ohio’s five-year strategic plan for education, Each Child, Our Future. The strategic plan acknowledges a major education policy shift around technology. A student’s ability to use technology strategically is now identified as foundational and just as important as mathematics and ...

Memory is fundamental in the operation of a computer. When combined with a CPU, the ability to run sets of instructions (programs) and store working data becomes possible. Random-access memory (RAM) is a well-known type of memory and is so-called because of its ability to access any location in memory with roughly the same time delay. Dynamic rando...
Invented by Robert Dennard in 1966 at IBM, DRAM works much differently than other types of memory. The fundamental storage cell within DRAM is composed of two elements: a transistor and a capacitor. When a bit needs to be put in memory, the transistor is used to charge or discharge the capacitor. A charged capacitor represents a logic high, or '1',...
DRAM can come in different forms depending on the application. Figure 2 shows a DIMM (dual inline memory module) that contains multiple onboard DRAM chips. This DIMM contains 1 GB of memory, but notice the “2Rx8” printed on the sticker. The 2R means that this module is of rank 2, while the x8 (pronounced “by eight”) denotes the output width of the ...
In this article, we examined the basic principle of operation behind dynamic random access memory, or DRAM. DRAM is extremely common in personal computers and is a basic component that any computer needs to work properly. DRAM works by using the presence or absence of charge on a capacitor to store data. Since a single DRAM cell is composed of only...
Jul 25, 2024 · The 2017 Ohio Learning Standards for Technology define what students need to know and be able to do to succeed in a technological world. Revised from the 2003 Ohio Technology Academic Content Standards, the 2017 standards incorporate three key technology disciplines: Information and Communications Technology. Society and Technology.
A schematic drawing depicting the cross-section of the original one-transistor, one-capacitor NMOS DRAM cell. It was patented in 1968. The cryptanalytic machine code-named "Aquarius" used at Bletchley Park during World War II incorporated a hard-wired dynamic memory. Paper tape was read and the characters on it "were remembered in a dynamic ...

Aug 22, 2022 · Humans like to work with numbers in the decimal (base 10) system (with ten different digits ranging from 0 through 9). Computers, on the other hand, work using an entirely different number system called binary based on just two numbers, zero (0) and one (1). In the decimal system, the columns of numbers correspond to ones, tens, hundreds ...
