  1. 4. A small text file (up to 4KB) created by a website that is stored in the user's computer either temporarily for that session only or permanently on the hard disk (persistent cookie). Cookies provide a way for the website to recognize you and keep track of your preferences
  2. 6. (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is typically via DSL, cable or FiOS; however, ISPs can deliver service via satellite, dial-up, ISDN, private lines and wireless. Customers are generally billed a fixed rate per month, but other charges may apply.
  3. 7. Machinery and equipment (CPUs, drives, keyboards, printers, scanners, cables, etc.). In operation, a computer is both hardware and software, and one is useless without the other. The hardware design specifies the command format it can follow, and the software instructions in that format tell it what to do.
  4. 8. The fundamental display element of an electronic screen or bitmapped image. Screen resolution is rated by the number of horizontal and vertical pixels; for example, 1024x768 means 1,024 pixels are displayed in each row, and there are 768 rows (lines). Likewise, bitmapped images are sized in pixels: a 350x250 image has 350 pixels across and 250 down.
  5. 9. Th The most widely used hardware interface for attaching peripherals to a computer. There are at least two USB ports on laptops and four on desktop computers, while USB "hubs" provide more connections (see below). After appearing in 1997, USB became the standard for connecting keyboards, mice, printers and hard drives, eventually replacing the PC's serial and parallel ports and the Apple Desktop Bus on Macse address that defines the route to a file on an Internet server
  6. 10. The transmission capacity of an electronic pathway such as a communications line, computer bus or computer channel. Digital bandwidth is the number of pulses per second measured in bits per second (bps). For example, Ethernet transmits at different speeds, including 10 Mbps, 100 Mbps and 1000 Mbps
  7. 11. Instructions for the computer. A series of instructions that performs a particular task is called a "program." The two major software categories are "system software" and "application software."

  1. 1. The primary method for keeping a computer secure from intruders. A firewall allows or blocks traffic into and out of a private network or the user's computer. Firewalls are widely used to give users secure access to the Internet as well as to separate a company's public Web server from its internal network.
  2. 2. To store data locally in order to speed up subsequent retrievals.
  3. 3. An inhouse website that serves employees only, and most medium-sized and large companies have one. Although intranet pages may have links to websites on the Internet, the intranet is not exposed to, or is accessed by, the general public. It provides a standard way to publish company policy, news, schedules, medical and insurance forms and training manuals. The intranet is also a venue for publishing blogs, wikis and social activities such as sports and exercise schedules.
  4. 4. The computing part of the computer. Also called the "processor," it is made up of the control unit and ALU. Today, the CPUs of almost all computers are contained on a single microprocessor chip. In fact, multiple processing units on one chip are commonplace
  5. 5. Pronounced "fishing," it is a scam to steal valuable information such as credit card and social security numbers, user IDs and passwords. Also known as "brand spoofing," an official-looking e-mail is sent to potential victims pretending to be from their bank or retail establishment. E-mails can be sent to people on selected lists or any list, expecting some percentage of recipients will actually have an account with the organization.
  6. 9. The most widely used hardware interface for attaching peripherals to a computer. There are at least two USB ports on laptops and four on desktop computers, while USB "hubs" provide more connections (see below). After appearing in 1997, USB became the standard for connecting keyboards, mice, printers and hard drives, eventually replacing the PC's serial and parallel ports and the Apple Desktop Bus on Macs
  7. 10. A website that contains text entries in reverse chronological order (most recent entry first). Blogs cover everything from the latest news about a topic to personal journals to "ranting and raving." Written by one person or a group of contributors, entries contain commentary, observations and opinions and may include images, audio, video, links to other sites, as well as a search facility for finding past entries.
