CONNECTIONS SCSI The Small Computer System Interface (SCSI) is standard that enables up to seven devices (such as scanners, disk drives CD - ROM players and their peripherals) to be connected to a computer. All current Macintoshes have SCSI built in whereas for PCs the interface has to be installed.Modern SCSI drivers enable data transfer that is as high as 20 to 40 megabits per second but they can be difficult to set up since the cabling used to sensitive to length and resistance.
CONNECTIONS MCI The Media Control Interface (MCI) is a unified, command driven method for software to talk to related multimedia peripheral devices.Any hardware device can be connected to a computer running Window.Using appropriate drivers it is possible to control the device using codes or simple command strings.
E-mail. 3. Elektron pochta.
Electronic mail (email or e-mail) is a method of transmitting and receiving messages using electronic devices. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence e- + mail). Email is a ubiquitous and very widely used communication medium; in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries.
Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need to connect, typically to a mail server or a webmail interface to send or receive messages or download it.
Originally an ASCII text-only communications medium, Internet email was extended by Multipurpose Internet Mail Extensions (MIME) to carry text in other character sets and multimedia content attachments. International email, with internationalized email addresses using UTF-8, is standardized but not widely adopted.[1]
