Teacher: Now, understand the problem? Solve this instance: Context: In consumer electronics, a remote control is a component of an electronic device such as a television set, DVD player, or other home appliance, used to operate the device wirelessly from a short distance. Remote control is primarily a convenience feature for the consumer, and can allow operation of devices that are out of convenient reach for direct operation of controls. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside or when a Digital Light Processing projector that is mounted on a high ceiling is controlled by a person from the floor level., Arithmetic or arithmetics (from the Greek  "arithmos", "number") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between themaddition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms "arithmetic" and "higher arithmetic" were used until the beginning of the 20th century as synonyms for "number theory" and are sometimes still used to refer to a wider part of number theory., The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a "network of networks" that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing., In computing, a file system or filesystem is used to control how data is stored and retrieved. Without a file system, information placed in a storage medium would be one large body of data with no way to tell where one piece of information stops and the next begins. By separating the data into pieces and giving each piece a name, the information is easily isolated and identified. Taking its name from the way paper-based information systems are named, each group of data is called a "file". The structure and logic rules used to manage the groups of information and their names is called a "file system"., An access control list ( ACL ) , with respect to a computer file system , is a list of permissions attached to an object . An ACL specifies which users or system processes are granted access to objects , as well as what operations are allowed on given objects . Each entry in a typical ACL specifies a subject and an operation . For instance , if a file object has an ACL that contains ( Alice : read , write ; Bob : read ) , this would give Alice permission to read and write the file and Bob to only read it ., The bit is a basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a . The term "bit" is a portmanteau of binary digit. In information theory, the bit is equivalent to the unit "shannon", named after Claude Shannon., A control system manages, commands, directs or regulates the behaviour of other devices or systems. It can range from a home heating controller using a thermostat controlling a domestic boiler to large Industrial control systems which are used for controlling processes or machines. , A smartphone is a mobile phone (also known as cell phones or cell mobiles) with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use. Smartphones, which are usually pocket-sized, typically combine the features of a mobile phone, such as the abilities to place and receive voice calls and create and receive text messages, with those of other popular digital mobile devices like personal digital assistants (PDAs), such as an event calendar, media player, video games, GPS navigation, digital camera and digital video camera. Smartphones can access the Internet and can run a variety of third-party software components ("apps" from Google Play, Apple App Store, etc). They typically have a color display with a graphical user interface that covers more than 76% of the front surface. The display is almost always a touchscreen and sometimes additionally a touch-enabled keyboard like the Priv/Passport BlackBerrys, which enables the user to use a virtual keyboard to type words and numbers and press onscreen icons to activate "app" features., A microwave oven (commonly referred to as a microwave) is a kitchen appliance that heats and cooks food by exposing it to microwave radiation in the electromagnetic spectrum. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer of a homogeneous, high water content food item; food is more evenly heated throughout (except in heterogeneous, dense objects) than generally occurs in other cooking techniques., A personal computer (PC) is a multi-purpose electronic computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by a person using a graphical user interface such as Windows. The versatility of a personal computer is greatly enhanced by the use of peripheral devices such as a keyboard, monitor, printer, mouse, speakers, and an external hard drive., A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers., A mobile device (or handheld computer) is a small computing device, typically, small enough to hold and operate in the hand and having an operating system capable of running mobile apps. These may provide a diverse range of functions. Typically, the device will have a display screen with a small numeric or alphanumeric keyboard or a touchscreen providing a virtual keyboard and buttons (icons) on-screen. Many such devices can connect to the Internet and interconnect with other devices such as car entertainment systems or headsets via Wi-Fi, Bluetooth or near field communication (NFC). Integrated cameras, digital media players, mobile phone and GPS capabilities are common. Power is typically provided by a lithium battery. , Computing is any goal-oriented activity requiring, benefiting from, or creating a mathematical sequence of steps known as an algorithm  e.g. through computers. Computing includes designing, developing and building hardware and software systems; processing, structuring, and managing various kinds of information; doing scientific research on and with computers; making computer systems behave intelligently; and creating and using communications and entertainment media. The field of computing includes computer engineering, software engineering, computer science, information systems, and information technology., Subject: access control list, Relation: part_of, Options: (A) algebra (B) building (C) cell (D) computer (E) computer science (F) design (G) digital media (H) electromagnetic spectrum (I) electronic (J) electronics (K) engineering (L) event (M) file system (N) google (O) government (P) hand (Q) information theory (R) internet (S) internet protocol (T) internet protocol suite (U) kitchen (V) logic (W) mathematics (X) may (Y) medium (Z) name ([) navigation (\) number theory (]) operating system (^) person (_) software (`) system (a) technology (b) text (c) the unit (d) top (e) uniform (f) variety (g) world wide web
