Year 315 (CCCXV) was a common year starting on Saturday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Constantinus and Licinianus (or, less frequently, year 1068 Ab urbe condita). The denomination 315 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number.
Acer often refers to:
- Acer (plant), the genus of trees and shrubs commonly known as maples
- Acer Inc., a computer company in Taiwan

Celeron is a series of IA-32 and x86-64 computer microprocessors targeted at low-cost personal computers, manufactured by Intel from 1998 until 2023.
The first Celeron-branded CPU was introduced on April 15, 1998, and was based on the Pentium II. Celeron-branded processors released from 2009 to 2023 are compatible with IA-32 software. They typically offer less performance per clock speed compared to flagship Intel CPU lines, such as the Pentium or Core brands. They often have less cache or intentionally disabled advanced features, with variable impact on performance. While some Celeron designs have achieved strong performance for their segment, the majority of the Celeron line has exhibited noticeably degraded performance. This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron range.
In September 2022, Intel announced that the Celeron brand, along with Pentium, were to be replaced with the new "Intel Processor" branding for low-end processors in laptops from 2023 onwards. This applied to desktops using Celeron processors as well, and was discontinued around the same time laptops stopped using Celeron processors in favor of "Intel Processor" processors in 2023.
Then, Intel released the N100 CPU, an evolution of the mobile Celeron, in 2023. The Celeron had two cores, but the N100 has four cores. The maximum operating clock is 3.40GHz, the TDP is 6W. The maximum RAM capacity is 16GB.
Chromebook (sometimes stylized in lowercase as chromebook) is a line of laptops, desktops, tablets and all-in-one computers that run ChromeOS, a proprietary operating system developed by Google.
Chromebooks are optimised for web access. They also run Android apps, Linux applications, and Progressive web apps which do not require an Internet connection. They are manufactured and offered by various OEMs.
The first Chromebooks shipped on June 15, 2011. As of 2020, Chromebook's market share is 10.8%, placing it above the Mac platform; it has mainly found success in education markets.
Since 2021, all Chromebooks receive 10 years of regular automatic updates with security patches from Google, previously it was 8 years. Chromebooks can be repurposed with other operating systems and/or used for other purposes if required.
Intel Corporation is an American multinational corporation and technology company headquartered in Santa Clara, California, and incorporated in Delaware. Intel designs, manufactures, and sells computer components such as CPUs and related products for business and consumer markets. It is considered one of the world's largest semiconductor chip manufacturers by revenue and ranked in the Fortune 500 list of the largest United States corporations by revenue for nearly a decade, from 2007 to 2016 fiscal years, until it was removed from the ranking in 2018. In 2020, it was reinstated and ranked 45th, being the 7th-largest technology company in the ranking.
Intel supplies microprocessors for most manufacturers of computer systems, and is one of the developers of the x86 series of instruction sets found in most personal computers (PCs). It also manufactures chipsets, network interface controllers, flash memory, graphics processing units (GPUs), field-programmable gate arrays (FPGAs), and other devices related to communications and computing. Intel has a strong presence in the high-performance general-purpose and gaming PC market with its Intel Core line of CPUs, whose high-end models are among the fastest consumer CPUs, as well as its Intel Arc series of GPUs. The Open Source Technology Center at Intel hosts PowerTOP and LatencyTOP, and supports other open source projects such as Wayland, Mesa, Threading Building Blocks (TBB), and Xen.
Intel was founded on July 18, 1968, by semiconductor pioneers Gordon Moore (of Moore's law) and Robert Noyce, along with investor Arthur Rock, and is associated with the executive leadership and vision of Andrew Grove. The company was a key component of the rise of Silicon Valley as a high-tech center, as well as being an early developer of SRAM and DRAM memory chips, which represented the majority of its business until 1981. Although Intel created the world's first commercial microprocessor chip—the Intel 4004—in 1971, it was not until the success of the PC in the early 1990s that this became its primary business.
During the 1990s, the partnership between Microsoft Windows and Intel, known as "Wintel", became instrumental in shaping the PC landscape and solidified Intel's position on the market. As a result, Intel invested heavily in new microprocessor designs in the mid to late 1990s, fostering the rapid growth of the computer industry. During this period, it became the dominant supplier of PC microprocessors, with a market share of 90%, and was known for aggressive and anti-competitive tactics in defense of its market position, particularly against AMD, as well as a struggle with Microsoft for control over the direction of the PC industry.
Since the 2000s and especially since the late 2010s, Intel has faced increasing competition, which has led to a reduction in Intel's dominance and market share in the PC market. Nevertheless, with a 68.4% market share as of 2023, Intel still leads the x86 market by a wide margin. In addition, Intel's ability to design and manufacture its own chips is considered a rarity in the semiconductor industry, as most chip designers do not have their own production facilities and instead rely on contract manufacturers (e.g. TSMC, Foxconn and Samsung), as AMD and Nvidia do.
A sleeve (Old English: slīef, a word allied to slip, cf. Dutch sloof) is the part of a garment that covers the arm, or through which the arm passes or slips.
The sleeve is a characteristic of fashion seen in almost every country and time period, across a myriad of styles of dress. Styles vary from close-fitting to the arm, to relatively unfitted and wide sleeves, some with extremely wide cuffs. Long, hanging sleeves have been used variously as a type of pocket, from which the phrase "to have up one's sleeve" (to have something concealed ready to produce) comes. There are many other proverbial and metaphorical expressions associated with the sleeve, such as "to wear one's heart upon one's sleeve", and "to laugh in one's sleeve".
Early Western medieval sleeves were cut straight, and underarm triangle-shaped gussets were used to provide ease of movement. In the 14th century, the rounded sleeve cap was invented, allowing a more fitted sleeve to be inserted, with ease around the sleeve head and a wider cut at the back allowing for wider movement. Throughout the 19th century and particularly during the Victorian era in Western culture, the sleeves on women's dress at times became extremely wide, rounded or otherwise gathered and 'puffy', necessitating the need for sleeve supports worn inside a garment to support the shape of the sleeve. Various early styles of Western sleeve are still found in types of academic dress.
Sleeve length varies in modern times from barely over the shoulder (cap sleeve) to floor-length (as seen in the Japanese furisode). Most contemporary shirt sleeves end somewhere between the mid-upper arm and the wrist.
