A 19-inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is 19 inches (482.6 mm) wide. The 19 inch dimension includes the edges or ears that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers, telecommunications equipment and networking hardware, audiovisual production gear, professional audio equipment, and scientific equipment.
A DIMM is a popular type of memory module used in computers. It is a printed circuit board with one or both sides holding DRAM chips and pins. The vast majority of DIMMs are manufactured in compliance with JEDEC memory standards, although there are proprietary DIMMs. DIMMs come in a variety of speeds and capacities, and are generally one of two lengths: PC, which are 133.35 mm (5.25 in), and laptop (SO-DIMM), which are about half the length at 67.60 mm (2.66 in).
Paper size standards govern the size of sheets of paper used as writing paper, stationery, cards, and for some printed documents.
Brickwork is masonry produced by a bricklayer, using bricks and mortar. Typically, rows of bricks called courses are laid on top of one another to build up a structure such as a brick wall.
A futon is a traditional Japanese style of bedding.
A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Classification systems vary between different countries, and loading gauges may vary across a network, even if the track gauge is uniform.
A bedroom or bedchamber is a room situated within a residential or accommodation unit characterized by its usage for sleeping. A typical western bedroom contains as bedroom furniture one or two beds, a clothes closet, and bedside table and dressing table, both of which usually contain drawers. Except in bungalows, ranch style homes, ground floor apartments, or one-storey motels, bedrooms are usually on one of the floors of a dwelling that is above ground level. Beds range from a crib for an infant; a single or twin bed for a toddler, child, teenager or single adult; to bigger sizes like a full, double, queen, king or California king). Beds and bedrooms are often devised to create barriers to insects and vermin, especially mosquitoes, and to dampen or contain light or noise to aid sleep and privacy.
A mattress is a large, usually rectangular pad for supporting a person lying down, especially for sleeping. It is designed to be used as a bed, or on a bed frame as part of a bed. Mattresses may consist of a quilted or similarly fastened case, usually of heavy cloth, containing materials such as hair, straw, cotton, foam rubber, or a framework of metal springs. Mattresses may also be filled with air or water.
Bedding, also called bedclothes or bed linen, is the materials laid above the mattress of a bed for hygiene, warmth, protection of the mattress, and decorative effect. Bedding is the removable and washable portion of a human sleeping environment. Multiple sets of bedding for each bed are often washed in rotation and/or changed seasonally to improve sleep comfort at varying room temperatures. Most standardized measurements for bedding are rectangular, but there are also some square-shaped sizes, which allows the user to put on bedding without having to consider its lengthwise orientation.
A shoe size is an indication of the fitting size of a shoe for a person.
A unit load device (ULD) is a container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows preloading of cargo, provided the containerised load fits in the aircraft, enabling efficient planning of aircraft weight and balance and reduced labour and time in loading aircraft holds compared with 'bulk-loading' single items of cargo or luggage by hand. Each ULD has its own packing list or manifest so that its contents can be tracked. A loaded aircraft cargo pallet secured with a cargo net also forms a ULD, but its load must be gauged for size in addition to being weighed to ensure aircraft door and hold clearances.
A comforter, also known as a doona in Australian English, or a continental quilt or duvet in British English, is a type of bedding made of two lengths of fabric or covering sewn together and filled with insulative materials for warmth, traditionally down or feathers, wool or cotton batting, silk, or polyester and other down alternative fibers. Like quilts, comforters are generally laid over a top bed sheet and used to cover the body during sleep. Duvets are another form of quilt, traditionally filled with feathers, though since the late 20th century often made of synthetic fibres or down alternatives.
An infant bed is a small bed especially for infants and very young children. Infant beds are a historically recent development intended to contain a child capable of standing. The cage-like design of infant beds restricts the child to the bed. Between one and two years of age, children are able to climb out and are moved to a toddler bed to prevent an injurious fall while escaping the bed.
Since the widespread adoption of reel-to-reel audio tape recording in the 1950s, audio tapes and tape cassettes have been available in many formats. This article describes the length, tape thickness and playing times of some of the most common ones.
A rack unit is a unit of measure defined as 1+3⁄4 inches (44.45 mm). It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed as multiples of rack units. For example, a typical full-size rack cage is 42U high, while equipment is typically 1U, 2U, 3U, or 4U high.
A sofa bed or sofa-bed is a multifunctional furniture typically consisting of a sofa or couch that, underneath its seating cushions, hides a metal frame and thin mattress that can be unfolded or opened up to make a bed. A western-style futon differs from a sofa bed, although sofa beds using futon mattresses are common.
The scale length of a string instrument is the maximum vibrating length of the strings that produce sound, and determines the range of tones that string can produce at a given tension. It is also called string length. On instruments in which strings are not "stopped" or divided in length, it is the actual length of string between the nut and the bridge.
Clothing sizes are the sizes with which garments sold off-the-shelf are labeled. Sizing systems vary based on the country and the type of garment, such as dresses, tops, skirts, and trousers. There are three approaches:
A daybed is an item of furniture used as a bed as well as for lounging, reclining, and seating in a common room. It may be considered a form of multifunctional furniture. Their frames can be made out of wood, metal, or a combination of wood and metal. They are a cross between a chaise longue, a couch, and a bed.
The International L series was introduced by International Harvester in fall 1949 as the replacement for the KB series and were available as everything from light pickup trucks and delivery vehicles to full-size tractor-trailers. Electric wipers, a radio, and a clock were optional. International would continue to produce the line until 1953 when it was replaced by the R series.
